Roger Smith Posted September 5, 2021 Share Posted September 5, 2021 Toronto has had a weather observatory for over 180 years now, having started up on March 1st, 1840. The New York City Central Park series goes back to 1869. I also link to a weather journal maintained by Alexis Caswell at Providence RI from 1831 to 1860. The material in this thread is being copied over to American Weather Forum from its current location, the Net-weather forum in the UK. There will be one limitation in bringing the material here, namely, a smaller limit on attachment sizes will mean that links to supporting excel files created by myself will not be possible here. For those I may need to post links back to net-weather. I would just post that link in general but I wanted to create a second location where the data were accessible. Eventually I will also have an independent website to host this research. The thread was exclusively about the Toronto weather records for its first year of existence and then added NYC with comparisons to the Toronto data. So most of the second half of the thread is about the NYC data. If you start looking through this thread, at some point you may wonder where the NYC data is, so the answer is that it follows the posting of most of the Toronto data summaries. This is the thread that is now fully copied over to here: https://www.netweather.tv/forum/topic/93113-toronto-180-a-north-american-data-base-of-180-years-now-includes-nyc-1869-2020/#comments ========================================================== this is a link to the Alexis Caswell Providence RI weather journal. https://books.google.ca/books?id=oYY_AAAAcAAJ&printsec=frontcover#v=onepage&q&f=false =========================================================== (introduction to net-weather thread posted there Jan 19, 2020. Note, edited the thread title on Net-weather recently as shown below) Toronto-180 -- a North American data base of 182 years -- now includes NYC 1869-2022 I am now ready to post data from the Toronto-180 project. Toronto City is the current name of the weather station that operated as "Toronto" from 1840 to 2003. The location has always been somewhere around the modern-day University of Toronto campus which is located about 4 kms inland from Lake Ontario and near the northwest perimeter of the extensive central business district of the city (current metropolitan population 4.5 million). From 1840 to about 1880, the weather station was in a rural area on the outskirts of a much smaller community which grew to a population of about 10,000 when it began to surround the farmland where this weather station originally existed. (information added by edit on April 18) ... Although the station may have been near Fort York on the lakeshore briefly in 1840, it appears to have moved to the future site of the University of Toronto within a year or so, and until 1907 it was located where Kings College would eventually be situated, which nowadays is no longer an entity (the U of T has a number of colleges but this one no longer exists). That location was approximately 0.1 km southeast of Hart House in the central portion of the campus (now). Construction of University College nearby in the years 1906 to 1908 created so much dust and other disruption that it was decided to move the weather station, which included a geomagnetism observatory and a telescope, to a quieter location at the northwest margin of the campus, at 315 Bloor Street West, in a building that would later become the headquarters of the Dominion Weather Bureau, an antecedent of the modern day weather agency, Environment Canada (Meteorological Services). That headquarters functioned until 1971 when a new building was opened in suburban North York (Downsview), and the building in question has now become the admissions and bursary offices of the U of T. (original text resumes) It was then (c.1908) moved about 1 km north to the former location of the headquarters of the "Dominion Weather Bureau" which became the Atmospheric Environment Service around 1969 and then Environment Canada in 1976. It was at that time that observations switched from the Imperial system to metric. The weather station was operated as a first-class reporting site for most of the years of its existence and has only recently been downgraded to a climatological station. Around 2003, the instruments were moved away from the former headquarters building (at 315 Bloor St W, next to Varsity Stadium, at the north end of the campus), and placed in a suitable open grassy area near Trinity College about 0.3 km to the southeast. (again edited in, this final location is about midway between the original pre-1907 site and the subsequent 1908-2003 location and all are in similar terrain within a five minute walk of each other). The station name was then changed to "Toronto City." From 2003 to 2017, a separate observation program continued (under the name Toronto) recording only daily precip and snowfall. Meanwhile the Toronto City station recorded temperatures and daily precip, snow depths but no daily snowfall amounts. The purpose of the secondary station (which retained the name of the original) was to record snowfall and it only operated from mid-November to mid-April in most years (2003-17). It ceased to report in the 2017-18 winter season. The author has collected all data available and filled in a few observation gaps (most of them since 2013) from nearest possible locations well within the urban heat island. North York (located 13 km north) was preferred when available. These additional observations have changed some monthly mean temperatures and total precip values from published values slightly, as the practice of Environment Canada was to calculate means from available data unless a significant number of days were missing in which case no means or totals were assigned at all. In some cases, missing data was considerably different from the reported monthly mean and an adjustment was necessary. Most of the missing precipitation was (by luck of the draw) rather minor but one case was found where a heavy rainfall occurred on a missing date. All of these changes are logged in the excel file that is being developed. The temperature adjustments average out to almost zero (most changes to monthly means were of 0.1 or 0.2 C deg). The climate of Toronto is typical of eastern North America with large variations from month to month and day to day. There is a cold winter season that usually sets in around late November or early December and lasts to late February, March or in some cases early April. Snow can fall at any point from October to May (and traces have fallen in June and September). Snowfall is more reliable from early December to mid-March. But rain always falls during the winter season except in the coldest months each decade. Monthly rainfalls are fairly evenly distributed but year to year variations are very large. Monthly temperatures also vary by standard deviations of 3 or 4 C deg. The absolute range of monthly mean temperatures is 12-13 deg in winter and 5-6 deg in summer. A hot and rather humid summer season makes a few appearances in May and early June, then often sets in with a few cooler interludes for most of July and August. September tends to be warm and less humid in most years, and there is often a considerable change to autumnal weather around the equinox. October is either a pleasant "Indian summer" regime or in some years a windy and cool month with mixed wintry showers at times. This thread will document all aspects of the Toronto climate in the same style that I adopted for the CET studies in the historical weather section (over on net-weather). Although it might be appropriate to post it there, it also has climate change implications. Toronto is probably a good proxy for the eastern North American climate in general. Its extremes tend to be of similar magnitude and timing to those experienced in the eastern U.S. and if a month is very warm or very warm at Toronto, chances are high that it will also be that way in Chicago, New York, Washington and Boston (and most points in between). Anomaly patterns in eastern North America tend to have the shape and extent of typical large highs and lows that move through the region on a regular basis. Some details of this correlation are examined in more detail when we get to the NYC portion of this study. There are a few local effects worth noting. A strong cooling lake breeze can blow in during settled periods in the spring, and drop temperatures by 5-10 C deg relative to more inland locations. Some research indicates that the development of a large city with tall buildings closer to the lakeshore can inhibit this lake breeze, and this may be a factor in assessing how cool springs and early summers were in the 19th century. A weather journal taken in Providence RI has evidence of a blistering heat wave in July 1849 (highs of 97 F were noted) that translated to rather subtle warmth at Toronto (highs 85-90), and from experience I would say that in a modern climate setting that difference might have been reduced by several degrees. The urban heat island probably grew fastest for this location around 1900 to 1930. I have assessed its strength overall at a conservative 1.1 C deg averaged over all types of weather, and as large as 4-6 C deg on cool, clear nights. It might seem larger to a casual observer, but rural stations outside the urban heat island are also at a higher elevation and would have a cooler temperature regime than the Toronto city location even without the presence of the large city. Wind speeds over 30 km/hr tend to reduce the urban heat island. Cloud and rainfall also tend to reduce it considerably. Eventually I will publish tables of temperature rankings and supplement those with adjusted temperatures for urban heat island (as the CET managers are doing), taking off 1.1 C from readings since 1981, 1.0 for those 1971-1980, 0.9 for 1961-70, 0.8 for 1951-60, 0.7 for 1941-50, 0.6 for 1931-40, 0.5 for 1921-30, 0.4 for 1911-1920, 0.3 for 1901-1910, and 0.2 for data 1891 to 1900, 0.1 for 1881 to 1890. This should make the urban effect less of an advantage to later years in comparison. The warming since around the 1880s has been considerably larger than 1.1 C and at a faster pace in the early part of the urban development. There would always be a possibility of revising the urban heat island correction. But in general terms, I believe that the modern warming of the climate is about an equal combination of natural variability augmented by the AGW signal, plus the urban heat island. Some ask, isn't the urban heat island part of the AGW signal? Not really, the mixing of greenhouse gases into the free atmosphere is not confined to urban areas although it might largely originate there, whereas the urban heat island is specific to the urban setting and when the surplus heat is dissipated by stronger winds, the net effect on global temperatures is smaller than the AGW signal (by a factor of about 1:10). So you could perhaps say that the urban heat island dissipation cycle is something like 10 per cent of the AGW warming signal. The research file logs all record highs and lows in temperatures, and record high rainfalls and snowfalls. Tables will appear in this thread to summarize all of that. Eventually the research (excel) file can be shared but as the station did not open until March 1st of 1840, the "Toronto-180" project will not be complete until March 1st of this year. So I probably won't publish the file until we pass that point and I can insert values for January 2020 and February 2020 into the tables. (later edit _ as I am now adding some precip data to the excel files, those won't be fully available until May or June 2020, but the work is essentially complete as of April 2020 on the originally proposed Toronto 180 project, and this thread is the record of that). I will start the process with the average monthly temperatures and annual means (unadjusted for urban heat island). This may take an edit or two as it looks orderly on my screen but may not look that orderly on the post. Then I will post some shells of other tables to reserve space before any comments begin to appear. Please refrain from commenting for at least a day or two until I have these posts in place. I will fill them out as quickly as possible in the coming days. Note on metric conversion ... Canada adopted the metric system around 1976, but these files converted on June 1, 1978. Before that date, all of the values shown in the historical data internet files from source (Environment Canada) are exclusively Fahrenheit to Celsius conversion values. Starting on June 1, 1978, new values that do not occur in that conversion protocol appear (for example, max temp June 1 1978 is 22.0, for 72 F the value reported is always 22.2; the first metric rainfall observation was 0.2 mm, whereas the only choices available for Imperial unit conversion were 0.0 and 0.3 mm for 0.01" -- so while it's possible that the conversion started in May with the coincidence of all values happening to conform to conversion protocols, it seems most likely that the switch to metric in recording this station's data came on June 1, 1978.) Work is ongoing to provide all the same data tables for NYC (New York City Central Park), a station that opened near its current location in 1869 in mid-town Manhattan and has a similar parkland setting to the downtown Toronto site. To date all of the same temperature tables except daily records have been posted. Meanwhile the author has finished an excel file for the Toronto data including all precip data and plans to make this available at the end of 2020 once the December 2020 data are inserted into the files here (and there). NYC precip data are coming along too, Don Sutherland of American Weather Forum has kindly assisted me with provision of data sets in excel table format and eventually I will have that ready for sharing with climate researchers. Much of the NYC data can be easily accessed on the NWS New York City home page too. Link to comment Share on other sites More sharing options...
Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 (general comment -- the tables in this thread tend to wrap at higher screen mag settings, you may need to reduce your mag to 80 or 90 per cent to avoid the wrapped appearance, or just take the linked transfer over to the Net-weather version which does not seem to wrap at higher mag settings) ... Mean monthly temperatures (deg C) Note: Toronto began observations March 1, 1840. The values shown for Jan and Feb 1840 are ball-park estimates based on the weather journal of Alexis Caswell at Providence RI that overlaps the Toronto data from 1840 to 1860. January 1840 was quite a cold month by their local standards and February 1840 was milder than average. This allows me to calculate a rough annual average for the year. ___ JAN_ FEB_ MAR_ APR_MAY_ JUN_ JUL_AUG_ SEP_ OCT_NOV_ DEC__ANNUAL_ANNUAL to 0.01 C 1840 -7.0 -3.0 +1.2 6.7 12.4 15.8 19.5 19.0 13.0

This is significant because 1998 at 11.4 (from 11.40) is the warmest year in the records. (The Oct 2022 mean of 11.1 is revised down from the 11.2 shown in the website because 27th had no entry but a check of available data established a likely daily mean of 7.5 C for 27th, so adjusted this to 11.1 C).

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Ranked monthly and annual means As with the CET rankings, will start from coldest at the top to warmest at the bottom. These are the raw data before any corrections for urban heat island, a separate ranking table will be constructed later for the adjusted data. The size of the UHI reduction will be 1.1 C deg by 1980, with data adjusted after 1881 by 0.1 more each decade from that decade (1881-1890) to 1.0 in 1971-1980 then 1.1 to end of series. The table will appear in two parts, Jan to June and July to Dec with annual. Cold ranks are read as "first coldest, second coldest etc" from the top, warm ranks are read from the bottom of the tables (so that 182nd (July-Dec) warmest is coldest, and after Feb 2023 completes the data available for the first half of the year, 183rd warmest will be coldest there. Ranks for March to June 2023 are being added at bottom of part one of table, will be incorporated into table after Jan-Feb 2024 are known.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Annual Maximum and Minimum Temperatures The first two stats will always be in the calendar year. The winter minimum can be in the previous calendar year and refers to the winter season ending in March-April of the stated year. An annual minimum may not be the winter minimum of the winter in which it occurs. ... Temperatures recorded up to June 1, 1978 were in Fahrenheit degrees rounded to nearest whole number. Temperatures recorded after June 1, 1978 were to nearest 0.1 C but the equivalent F reading is shown in the table for continuity purposes.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Daily Temperature Records (January 1 to March 31) All readings taken 1840 to 1977 were in F deg (recorded to nearest whole number) and those taken from 1978 to 2020 were in tenths of degrees Celsius. My protocol for ties is to convert the smaller Celsius portion to F (whole numbers) since we have no indication of the precision of the F readings to 1977. There will be an effort made later to provide the actual C readings for records tied or broken since conversion began. Monthly extremes are shown in bold type.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Note: Precip data section now begins. North American precip monthly data always includes measurements of rainfall, snowfall and precip. For Toronto, snowfall was always converted at 10:1 ratios until 1962 (Apr) when the procedure changed to daily liquid equivalent added to rainfall to get precip totals. Therefore these tables will always add up rain and snow to the precip from 1840 to 1962 except that the values were directly converted and so the individual elements may round off in such a way that precip is not exactly rain plus snow (it was an exact total in the original format of inches -- the EC database converts each element separately to the metric equivalent so their totals may round off differently). An example would be Mar 1846 where 50.0 mm rain plus 5.8 cm snow gives 55.9 mm prec (original values 1.97"R+2.3"S = 2.20P) After 1962 the amounts will not necessarily add up since the snowfall portion was being converted daily to liquid equivalent (after and including Apr 1962). Since snowfall was no longer separately tabulated after 2017, the procedure recently has been for a snowfall estimate based on snow on ground reports and nearby location snowfall reports, as part of total precipitation back to the 10:1 method in the absence of anything more definitive being available. Also, there are some gaps in the snowfall data from years 1840 to 1842 and one gap in rainfall records in parts of 1844 and 1845. Months with no data available show up in these tables as "no d" or "no data." Precip values for months with rain but no snow data are shown as >(rain) in the snowfall season and as rain for May to October although May and October precip could still be slightly higher (June to Sept unlikely to be different for those months which are in the 1840s only). Such months with reported zero rainfall have prec "unk." __ Trace amounts of rain or snow are less than 0.1" -- it is possible that a month with several traces had a total of 0.1" or higher but the procedure was always to add the traces to a total of trace no matter how many occasions there may have been. In my ranking tables, trace is counted as a higher amount than zero. In general in all the precip tables, from 2003 to 2017 two stations were operational. Starting July 2003 the former "Toronto" station ceased operation and a new "Toronto City" (which had been running for about a year concurrently) took over the temperatures and daily precip. When the winter 2003-04 snowfall season began the old "Toronto" station reappeared. It has daily rainfall and snowfall amounts. This is called "Tor A" in my notes and the new station with the temperatures is called "Tor B." A more detailed explanation of procedures used can be found in the excel file starting from cell HM2004 (down and across to the right for several columns). It was established that Tor A probably read the rain and snow at an early morning hour while Tor B appears to be more calendar-day oriented. The problem in determining which to use for record amounts is that the former Toronto station (before 2003) was probably on that same early morning observation cycle for at least some of the time (I recall it was calendar day when used as a first order station around my one observation stint there in June 1969). So unfortunately the daily rain, snow and precip records are quite likely skewed to somewhat different reporting "days" but not by more than the following overnight period. The protocol was evidently to record at around 0700h and list the results on the preceding date (in other words, Tor B precip and possibly earlier Toronto precip end the following morning, and about three quarters of precip events have ended before midnight so in those cases, there may be no error introduced.)

only month with a radically different precip total after 1962 would be March 1976 when a heavy fall of sleet on 1st-2nd added about 40 mm liquid equivalent that was not directly included in the reported rain or snow for those days. But there is no telling what an observer before the 1962-and-on protocols would have reported in that situation. In fact, there is no really easy way to tell what different amounts the earlier precip totals might have shown, as the observers then might have back-constructed snowfall from liquid equivalent (meaning they were actually using the same system for precip and it would be the snowfall amounts that were changed as a result). There were numerous mixed falls "back in the day" and one wonders how the observers actually came up with the numbers they recorded for rain and snow amounts, did they modify them to equal the melted amount in a rain gauge? I know first-hand the practical problems involved in coming up with accurate rain and snow components for a mixed storm having dealt with a number of them in my observing period. You have perhaps 2.35" of melted l.e., a wet 12" snow pack, so what was the rainfall, and how do you classify periods of ice pellets, sleet or other mixed forms that fell in the event? Thus I saw no point in trying to rank months any other way than the direct from table numbers method. (which will be relevant when I publish the ranking tables.) Since constructing the table, I have estimated rainfalls for non-recorded months Oct 1844 to Mar 1845. In this portion of the table, the values for the months Jan to Mar 1845 would be as follows 1845 ____ 38.1_ 57.7 _ 95.8 __ 53.8 _ 48.3 _102.1___ 58.5 _ 07.1 _ 65.6 Link to comment Share on other sites More sharing options...
Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Precip for May to September 1840 to 2023 Note: All precip is rainfall for June to September (there were two months of June and also of September with trace amounts of snow, those months have an * symbol beside precip values). For May there are a small number of cases with measurable amounts of snow. Some years in the 1840s had missing snowfall data and it is assumed that these had no measured amounts although for each of them a trace amount is assumed (because of cold average temps) so the notation for these missing months in the 1840s is Tr** Sep 1842 was cold enough to have had traces of snow at least. ** These Mays had no snowfall data and could have had at least trace amounts. * These Junes or Septembers had trace amounts of snow ^ At least three days missing from Sep 1840, amount could be larger. > Rainfall only measured 13th to 31st Aug 1844, total could be larger.

The annual rainfall total for 1840 applies to March to December, no data recorded in Jan-Feb 1840. Since all snowfall missing in 1841 and 1842, precip for these years is shown as a rough estimate based on average amounts of snow in similar temperature cases. (e = estimate). The first half of 1842 with the missing snowfall was very mild and only 30 cm was allotted to add to 70 cm later in the year. There are no rain or precip totals for 1844 or 1845 due to substantial missing rainfall data. What does appear suggests these were wet years like 1842 and 1843 had been. (incomp = incomplete).

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Ranking Rainfall by Months -- ranks for precipitation also for June to September 184 years are ranked for Jan to June (1844 and 1845 incomplete data have some estimated monthly values) .. ranks are driest to wettest. The 185th grouping will be March-June 2024 and Jan-Feb 2025. These will be shown after the first half of the year ranking table. The incomplete value for August 1844 is ranked with an adjustment, and is probably within 10-20 ranks. 51.1 mm fell 13th to 31st, and 28 mm estimated for 1-12. The author estimated values for these missing months Oct 1844-Mar 1845, from newly reconstructed weather maps and other clues, and these six months are now placed in the tables in their appropriate locations with asterisks to remind readers that the values are estimates only. The median value (92) has changed to 92nd driest and 92nd wettest after Feb 2024. For both January to June and July to December data with 184 full years, rank reverses after 92: 92nd driest, then 92nd wettest, median is between these. Tied values are listed from earliest (top) to latest (bottom). Trace amounts are grouped as a class higher than 0.0 mm. ... because no measurable snow fell in any June, July, Aug or Sep, these ranks are also the ranks for total precip for those months. (May and Oct are similar but listed separately). Otherwise, precip ranks are shown in later tables, after the snowfall rankings.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Rankings for Snowfall (cms) by months (note to Am Wx readers, this post can wrap on some mobile devices, it appears as planned on a mainframe device. Solution may be to set a smaller level of magnification if it appears to be wrapping) Rankings for Snowfall (cms) by months The years 1840 to 1842 have no snowfall data. Later, the author estimated snowfall amounts for the winter months in those years and added them to known rainfalls to get estimated precipitation. These estimates appear below the columns of the rankings in the tables but are not themselves ranked. This means that we have 181 years available for ranking (1843 to 2023). The table therefore runs from ranks 01-90 (lower half of the snowfall totals) then a median value 91st, and then 90 to 01 (high totals). June and September are not shown, they each had two cases with a trace amount of snow (June 1859 and 1945, September 1918 and 1956). No snowfall has been reported in July or August. Therefore the table shows rankings for eight months (Jan, Feb, Mar, Apr, May, Oct, Nov, Dec). There are numerous cases of zero snowfall in May and October. These occupy the top three quarters or so of the ranks, followed by years with trace amounts then the few measurable amounts. Ties are listed from top to bottom in chronological order. As with the CET or EWP rankings that these tables are meant to duplicate for Toronto, the reader has the task of working out tied rankings, although I do format this table to show the least and most snowy months from the extremes to the median (which is now between the 90th least and 90th most snowy months). Annual and winter snowfall ranks will appear after the next table (monthly precip ranks).

____________________________________________________ Unranked estimates for (March) 1840 to (Dec) 1842 ... these estimated snowfalls using available maps and clues from temps, Providence obs, have been utilized to estimate precip values in these months using the known rainfall amounts (which the author determined are probably not precip but only rainfall). The winter of 1841-42 was very mild with copious amounts of rain, not much snowfall is assigned. Dec 1841 and Mar 1842 are shown as 0.0 because of the very mild and frequently rainy conditions but trace to 5 cm totals are probably within the realm of possibility for either month. Winter 1840-41 was more average by comparison; the available maps do not suggest very stormy conditions but there was little rain and cold enough temperatures with some opportunities evident from maps and temperature ranges on some days, so average amounts are assigned in that winter. The associated excel files show the dates to which these snowfalls are assigned as estimated snowfall entries in the logs. The author gained some confidence from the parallel task of assigning known monthly snowfall totals in the winter of 1844-45 to actual dates from comparing weather maps and events downstream at Providence. These known totals seemed to be about what the maps suggested might have fallen. 1840 ____ Jan n/a ____ Feb n/a ____Mar 10.0 _____ Apr Tr ______ May Tr ______ Oct Tr ____ Nov 9.0 _____ Dec 30.0 1841 ____ Jan 35.0 ___ Feb 35.0 ___Mar 20.0 _____ Apr Tr ______ May Tr ______ Oct Tr ____ Nov 15.0 ____ Dec 0.0 1842 ____ Jan 10.0 ___ Feb 10.0 ___Mar 10.0 _____ Apr 0.0 _____ May Tr _________ Tr _____ Nov 7.0 ______ Dec 35.0 ___________________________________________________________________________________________________________ Link to comment Share on other sites More sharing options...
Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Monthly precipitation (mm) rankings Monthly precipitation (mm) rankings The monthly precip values from 1843 to 1962 are based on 10:1 ratios for snowfall (10 cm snow = 10 mm precip). From 1963 to 2017 they are based on rainfall plus liquid equivalent of snowfall which continued to average close to 10:1 but varied from year to year in a range of about 8:1 to 12:1. Since Nov 2017 the snowfalls have been estimated and are once again combined with rainfall at the 10:1 ratio. June to September in this table is identical to the rankings for rainfall as there was no measurable snow in those months. Values for precip from March 1840 to December 1842 (where snow may have fallen) are based on estimates of snow and these estimates do not appear in the snowfall ranking tables. The winter of 1841-42 was rainy and quite mild so the snowfall amounts estimated for that winter are low. No additions are made for March or April 1840. The winter of 1840-41 was a more average winter and near average amounts have been added to those months (Nov 1840 to Apr 1841). The last two months of 1842 were rather cold and generous amounts of snow have been added to the rainfalls reported there. No rainfalls were reported from Oct 1844 to Mar 1845. These months appear as in the rainfall rankings, with estimates from weather map and other reconstructions, and these estimates are now ranked and appear in positions consistent with these estimates. August 1844 has only a partial monthly total from data 13th to 31st but this is shown in the table with an estimated value and asterisk with note below the table. Nov 1989 may also have had slightly more precip than shown in the source tables due to a probable data entry error on Nov 20, 1989.

July 2023 entered the table at 44th wettest (98.2 mm). Aug 2023 entered the table at 50th driest (45.9 mm). Sep 2023 entered the table at 7th driest (11.9 mm). Oct 2023 entered the table at 53rd driest (41.8 mm). Nov 2023 entered the table at 60th driest (52.1 mm). Dec 2023 entered the table at 60th wettest (76.9 mm). - ============================================== - notes * Aug 1844 rainfall 13th to 31st (1st to 12th missing est by author at 28.0 +51.1 known for 13-31). ** Nov 1989 has probable data entry error (20th) 10-15 mm more than this may have fallen. _________________________________ The monthly precip values from 1843 to 1962 are based on 10:1 ratios for snowfall (10 cm snow = 10 mm precip). From 1963 to 2017 they are based on rainfall plus liquid equivalent of snowfall which continued to average close to 10:1 but varied from year to year in a range of about 8:1 to 12:1. Since Nov 2017 the snowfalls have been estimated and are once again combined with rainfall at the 10:1 ratio. June to September in this table is identical to the rankings for rainfall as there was no measurable snow in those months. Values for precip from March 1840 to December 1842 (where snow may have fallen) are based on estimates of snow and these estimates do not appear in the snowfall ranking tables. The winter of 1841-42 was rainy and quite mild so the snowfall amounts estimated for that winter are low. No additions are made for March or April 1840. The winter of 1840-41 was a more average winter and near average amounts have been added to those months (Nov 1840 to Apr 1841). The last two months of 1842 were rather cold and generous amounts of snow have been added to the rainfalls reported there. No rainfalls were reported from Oct 1844 to Mar 1845. These months appear as in the rainfall rankings, with estimates from weather map and other reconstructions, and these estimates are now ranked and appear in positions consistent with these estimates. August 1844 has only a partial monthly total from data 13th to 31st but this is shown in the table with an estimated value and asterisk with note below the table. Nov 1989 may also have had slightly more precip than shown in the source tables due to a probable data entry error on Nov 20, 1989.

Dec 2023 entered the table at 60th wettest (76.9 mm). - ============================================== - - ============================================== - notes * Aug 1844 rainfall 13th to 31st (1st to 12th missing), added est 28 mm to known 51.1 mm. ** Nov 1989 has probable data entry error (20th) 10-15 mm more than this may have fallen. r = precip same as rainfall for this month, e = precip adjusted for possible snowfall (1840-42) ^ Oct 1844 estimated from maps and temps to have been a rather wet month (it is known that 12.0" snow fell around 29th-30th) -- tables added to file with estimates show a total of 85.1 mm rain and 115.6 mm precip with the snow added. Now placed at 17th wettest in the table. ^ Nov 1844 estimated from maps and temps to have been near normal (known snowfall of 20.3 cm) and with 36.9 mm estimated rainfall, for a total of 57.2 mm, comes out at 69th driest as shown in the table. ^ Dec 1844 relatively close to average also, with estimated 44.5 mm rainfall but only 10.7 cm snow known to have fallen, total precip would be 55.2 mm -- the month is now shown in the table as tied 66th driest (with 2005). ^ Jan 1845 estimated rainfall 38.1 mm for total (with known 57.7 cm snow) precip of 95.8 mm. This would rank 28th wettest. ^ Feb 1845 estimated rainfall 53.8 mm for total (with known 48.3 cm snow) precip of 102.1 mm. This would rank 12th wettest in the table. ^ Mar 1845 estimated rainfall 58.5 mm for total (with known 7.1 cm snow) precip of 65.6 mm. This would rank 78th wettest. ______________________________ Link to comment Share on other sites More sharing options...
Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Rankings for Annual Rainfall, Snowfall and Precipitation 1840-2023 There are 183 years available for ranking (1840-2022) although 1840 is missing Jan and Feb, and some snowfall values have been estimated to get approximate ranks for precipitation when rainfall is known. There were missing rainfall months in late 1844 and early 1845 so these two years are ranked from the data that are available, as explained in the notes after the table. 144.0 cm snowfall in 1840 appears as 87th heaviest, and is based on temperature correlations with snowfall, so the estimate is not very precise. The winter of 1839-40 is not ranked so the winter of 2022-23 appears in the table. All 2022 elements have been inserted into the table. 2023 elements will be listed at base of table, until winter 2023-24 snowfall total is known, after which, all values will enter and table will expand to 184 ranks. The entries for 1840-1841 and 1841-1842 winter snowfalls are very approximate based on average amounts of snow for the temperature ranges of those winters. While 1841-1842 is shown at 11th place (75 cm) to preserve the actual measured top ten snow-free winters, the amount of snow that was added to rainfalls in the precip section for those approximate rankings amounted to 35 cm for the winter which would rank lowest ahead of 2011-2012 currently the least snowy winter. The year 1842 was also ranked 11th with 80 cm (about half is assigned to December of that year). The rankings for 1841 and winter 1840-41 are closer to average values. The winter of 1842-43 had measured heavy snowfall amounts after January (138.3 cm Jan to May 1843) and the estimates for Nov-Dec 1842 are roughly equivalent in terms of proportions to the rest of the winter season as those were generally cold months and a check of historical weather maps shows potential for similar snowfall rates relative to normal. Since 1840 snowfall is unknown, a placeholder exists for it at the location considered most likely from winter month temperatures. That is located at 87th wettest 144 cm. It is unlikely to be much higher because Feb and Mar were quite mild in the region so most of the snow probably fell in Jan, Nov and Dec. The estimate is there mainly to keep other years in best possible rankings. These tables show two sets of snowfall ranks, calendar year (column 2), and winters (October to May total snowfalls in column 3). There are also rankings for summer rainfall totals (June to August) and extended summer rainfall (May to September) in the last two columns. Column 4 is for total annual precipitation. Once again these rankings run from 01 to 91 (dry or lower totals), a median value 92 both ways then 91 back to 01 (towards the wettest or highest totals).

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Daily Precipitation Records 1840 to 2023 (and Jan 9 2024) In the table, record values are listed by both imperial and metric amounts. The system used for measurement was imperial (inches) to 1978 and metric from (June 1) 1978 to present. The conversions from imperial are to nearest 0.1 mm or cm, the conversions from metric to inches are to nearest .01" (or 0.1" of snow). It would be possible for two measurements to tie from different systems but when this did occur in the data, close contenders were usually separated by some amount (see note b for Jan 26 below). There are a few tied values obtained from the same system of measurement though. There was one tied value even after conversions (Feb 7 snowfall measured as 8.0" in 1861 and 20.3 cm in 2013 could not be separated by conversion). After the daily (calendar day) records, a maximum 2-day snowfall is listed. This is done because a lot of snow events in the region occur overnight and are divided into two daily reports. The protocol is that the total amount shown as a 2-day maximum ends on the date listed. For example, the 9.1" of snow (1887) for Jan 1st below began on Dec 31, 1886. There are cases where the 2-day maximum is also the one-day maximum for the same date, and also cases where the second day total includes no further snowfall on that date, and more numerous examples of very small second-day amounts. An example of that can be seen with the snowfall on Jan 12, 1999 which continues to set a 2-day mark on 13th despite only slight additional snow . The changes of 2-day totals will sometimes reveal that a storm or at least a related snow interval was centered on one day and had additional amounts on both days adjacent. In the case of the latter snowfall, more additional snow had fallen on the 11th so the 2-day value on 12th was greater than the next day. The "notes" section will become busier in the summer and autumn rainfall records as any known links to tropical storms or other well-known events are listed. Some other information will appear under "notes" including, where space permits, some two-day rainfall totals (this will not be a rigorous log of two-day rainfall extremes however). Maximum precipitation is usually either the same day's maximum rainfall or snowfall event, or some combination of rain and snow involving one of them. About 80% of heavy mid-winter snowfalls have no associated rain or sleet, but with the other 20% there can be either small amounts or major mixed falls. Also most of the heavier rainfalls in the winter months occur in mild enough temperatures that they terminate without snow, but it is fairly common for a small additional amount of snow to fall at either end of the rainfall, usually the end portion. See the slight top-up of precip from rain on Jan 16, 1924 as an example of that. As it happens, the first entry (Jan 1, 1932) contains record rainfall and snowfall on the same date. This only happened once again in the data on Nov 6, 1951 (with both records set on same date). However, it is possible for an unrelated (to rain or snow maxima dates) to achieve maximum precipitation. This can happen if (a) enough rain and snow fall to surpass the precip value of the maximum rain or snow even where augmented by the other type, or (b) after 1962 if the snowfall liquid equivalent is either less than some rainfall value, or more than it, despite a straight 10:1 conversion not qualifying as max precipitation which would always be the case 1843 to 1962. Although the max precip for Jan 2nd below was from the record snowfall, it was larger with the liquid equivalent than would have been the case pre-1962, there was 1.0 mm rain added to the 38.0 cm snowfall and the precip was given as 52.0mm meaning that the 38.0 cm snow had l.e. of 51.0 mm. Pre-1962 this would have been recorded as 39.0 mm precip although it has occurred to me that observers back in that era may have derived some snowfalls from melted equivalents after the fact, so the distinction is not as obvious as at first glance. As a hypothetical of what that means, an observer might have been confronted with a large, somewhat melted snowfall, and decided to call the snowfall by a 10:1 ratio of melted precipitation, separating out an estimate for rainfall within the storm. I have the feeling that there was a practice of estimation to some extent because a larger than random portion of snowfalls (in particular before 1900) are either full inches or half inches rather than a spectrum of amounts ending in all tenths of an inch, which seemed to become the case later on (perhaps as observing procedures either improved or were more organized by time and employment -- the site was a first-order weather station for many years up to around 1969 and continued to be run quite rigorously after that, but as to measurement routines in the early part of the record, we have only the indirect clue of the number of events with measurements of whole inches, something that does not seem to occur with rainfall measurements). The author has first-hand experience with difficulties of separating out amounts of rain and snow in heavy mixed storms, for one thing, you tend to get rapid compaction from falling sleet or pellets, and also, the rain gauge can become iced over to some extent requiring frequent maintenance. Whether this was always done in the 19th century remains an unknown. Caswell's Providence Rhode Island record seems to indicate both understanding of these issues, and a diligent attitude towards managing them. The first case of a different date for max precip than either rain or snow was Jan 27 for 1967 (see below). Although neither rain nor snow daily records were broken, there was also sleet in this storm (the famous Chicago blizzard of Jan 26-27) and thus with the new measurement protocols introduced in 1962, the daily report is 0.44" rain, 3.8" snow and 1.59" precip. Two other occasions with similar outcomes were March 1-2 1976 and Apr 2-3 2003. Cases where the maximum daily precip comes from a combination of two non-record rainfall and snowfall amounts are shown in green. Cases where the maximum daily precip remains a value that is preserved due to a smaller than 10:1 snowfall conversion of a new snowfall record or value since 1963 (as for example Jan 28th below) are shown in red. The snowfall record providing this value was broken but not by enough to bring the lower liquid equivalent to a higher value. In theory the older record could have been the still-extant daily rainfall record. Cases where the maximum precip value is an augmented amount of either the record rain or snow are not highlighted and can be deduced from comparing the record value(s) associated. An issue regarding timing of amounts at two stations in operation 2003 to 2017 was unearthed during this stage as reported in the March-April section below. Notes have now been added to clarify status of rainfall records shown in Jan and Feb in the following table ... these notes are labelled (x) and appear after the other notes already shown. See above in the first precip table posted a longer discussion of this subject. (Tor A is the resumed and reduced version of Toronto 1840-2003, which only operated in winter months to record daily snowfalls along with rainfalls. ... ... Tor B is the new "Toronto City" site that began parallel to Toronto in 2002 and took over temperatures with daily precip July 2003. In general terms, from 2003 to 2017 Tor A was used November to March, Tor B was used April to October, but in some cases parts of the April and October data involving snow came from Tor A which then might have closed or opened at mid-month -- a blended record is required for these few cases). Monthly maximum values in each category are identified by bold type (e.g. rainfall for Jan 31, 1843, snowfall Jan 23, 1966). <<< January Daily Precip Records >>> DATE __ Max rain _____ year ___ Max snow ___ year ___ Max precip ___ year___ Max 2d snow (year) __ notes Jan 01__1.16" (29.5 mm) 1932 ___9.0" (22.9 cm) 1932__ 2.06" (52.3 mm) 1932 __ 9.1" (23.1 cm) 1887 Jan 02__1.00" (25.4 mm) 1870 __14.9" (38.0 cm) 1999__ 2.05" (52.0 mm) 1999 __14.9" (38.0 cm) 1999 _ also 2d s 13.0" (1932) Jan 03__0.95" (24.1 mm) 1907 ___6.2" (15.7 cm) 1924__ 0.95" (24.1 mm) 1907 __15.1" (38.4 cm) 1999 Jan 04__1.30" (33.0 mm) 1886 ___4.0" (10.2 cm) 1952__ 1.30" (33.0 mm) 1886 __ 7.2" (18.3 cm) 1924 _ also 1.22" (31.0 mm) r 1993 Jan 05__1.20" (30.5 mm) 1929 ___7.4" (18.8 cm) 1874__ 1.20" (30.5 mm) 1929 __ 7.4" (18.8 cm) 1874 Jan 06__1.90" (48.3 mm) 1841 ___7.5" (19.1 cm) 1950__ 1.90" (48.3 mm) 1841 __ 7.5" (19.1 cm) 1950 Jan 07__1.03" (26.2 mm) 1998 ___6.6" (16.8 cm) 1905__ 1.03" (26.2 mm) 1998 __10.2" (25.9 cm) 1905 Jan 08__1.37" (34.8 mm) 1935 __11.1" (28.2 cm) 1884__ 1.37" (34.8 mm) 1935 __11.1" (28.2 cm) 1884 Jan 09__1.11" (28.2 mm) 2024^___8.0" (20.3 cm) 1887__ 1.23" (31.2 mm) 2024^__15.7" (39.9 cm) 1884 Jan 10__0.94" (23.9 mm) 1843 ___7.0" (17.8 cm) 1865__ 0.94" (23.9 mm) 1843 __11.5" (29.2 cm) 1977 Jan 11__2.18" (55.3 mm) 2020 ___7.5" (19.1 cm) 1923__ 2.18" (55.3 mm) 2020 __ 7.5" (19.1 cm) 1923 Jan 12__1.42" (36.1 mm) 1844 ___8.3" (21.0 cm) 1999__ 1.42" (36.1 mm) 1844 __11.9" (30.4 cm) 1884 __ 2d r 68.1mm 2020 Jan 13__1.67" (42.4 mm) 1937 ___5.4" (13.7 cm) 1976__ 1.67" (42.4 mm) 1937 __ 8.5" (21.6 cm) 1999 Jan 14__1.33" (33.8 mm) 1899 __10.5" (26.6 cm) 1999__ 1.33" (33.8 mm) 1899 __10.7" (27.2 cm) 1999 __ also r 1.22" 30mm 1968** Jan 15__1.76" (44.8 mm) 1995 __11.5" (29.2 cm) 1968__ 1.76" (44.8 mm) 1968 __11.5" (21.6 cm) 1968 __ snow depth 65 cm 1999 Jan 16__1.00" (25.4 mm) 1924 __10.0" (25.4 cm) 1920__ 1.06" (26.9 mm) 1924 __11.5" (21.6 cm) 1968 Jan 17__1.30" (33.0 mm) 2006__ 14.2" (36.2 cm) 2022__ 1.42" (36.2 mm) 2022 __15.9" (39.3 cm) 1864 _ (x) (a) Jan 18__1.36" (34.5 mm) 1929 __10.5" (26.7 cm) 1895__ 1.36" (34.5 mm) 1929 __14.5" (37.0 cm) 1895 (a) Jan 19__0.65" (16.5 mm) 1933 __10.0" (25.4 cm) 1864__ 1.00" (25.4 mm) 1864 __14.0" (35.6 cm) 1920 Jan 20__1.25" (31.8 mm) 1842 __15.0" (38.1 cm) 1867__ 1.25" (31.8 mm) 1842 __15.0" (38.1 cm) 1867 Jan 21__0.53" (13.5 mm) 1895,1993 _6.3" (16.0 cm) 1881_ 0.88" (22.4 mm) 2010 _18.0" (45.7 cm) 1867 _ (x) Jan 22__1.06" (26.9 mm) 1957 __13.2" (33.5 cm) 1902__ 1.46" (37.1 mm) 1957 __15.7" (39.9 cm) 1902 Jan 23__0.76" (19.3 mm) 1898 __15.7" (39.9 cm) 1966__ 1.54" (39.1 mm) 1966 __16.6" (42.2 cm) 1966 Jan 24__1.65" (41.8 mm) 1979 __15.3" (38.9 cm) 1873__ 1.92" (48.8 mm) 1979 __19.5" (49.5 cm) 1873 _ (note b) Jan 25__0.58" (14.7 mm) 1964 ___7.0" (17.8 cm) 1855__ 0.70" (14.7 mm) 1964 __15.3" (38.9 cm) 1873 _ (x) Jan 26__0.82" (20.8 mm) 1849 ___8.0" (20.3 cm) 1895__ 0.82" (20.8 mm) 1849 __11.3" (28.7 cm) 1895 _ (note c) Jan 27__0.76" (19.3 mm) 1994 ___7.6" (19.3 cm) 2004__ 1.59" (40.4 mm) 1967 __11.6" (29.4 cm) 2004 Jan 28__0.44" (11.2 mm) 1975 ___7.9" (20.0 cm) 2019__ 0.60" (15.2 mm) 1871 __ 8.7" (22.1 cm) 1889 _ (note d) Jan 29__0.87" (22.0 mm) 2013 ___6.1" (15.5 cm) 1947__ 0.87" (22.0 mm) 2013 __ 8.3" (21.1 cm) 1947 _ (x) Jan 30__0.64" (16.3 mm) 1969 ___7.5" (19.1 cm) 1956__ 0.75" (19.1 mm) 1956 __ 8.1" (20.6 cm) 1947 Jan 31__2.50" (63.5 mm) 1843___7.1" (17.0 cm) 1982__2.50" (63.5 mm) 1843__12.5" (31.8 cm) 1852 ______________________________\ ^ (Jan 9 2024) _ Previous records: rainfall 0.70" (17.8 mm) 1964 and precip 0.80" (20.3 mm) 1887 (from 20.3 cm snowfall record) ... 1.11" R + 1.2" snow in 2024 = 1.23" precip ** Storm of Jan 14-15 1968 was freezing rain on 14th, heavy snow on 15th, considerable damage done to trees in the vicinity of the Toronto city weather office and the University of Toronto closed for a week due to power outages.

(b) Jan 24 1896 also had a heavy mixed fall of 1.18" (30.0 mm) rain, 5.2" (13.2 cm) snow, 1.70" (43.2 mm) precip. (c) Jan 26 1996 tied rainfall in terms of 20.6 mm vs 20.8 mm in 1849 but conversion was 0.81" vs 0.82". Same applies to the precip value associated. (d) The snowfall record is estimated from snow depth increase of 20 cm similar to other Toronto area reports -- the daily precip was 13.0 mm so the previous snowfall record's precip value (15.2 mm from 1871) continued to be the highest daily precip value. It should be noted in general that snowfalls were not assigned to dates in Jan 1843 (we do have the totals available) so that daily rainfall records on two occasions might have included some snow. The storm on Jan 31, 1843 was a very deep low that produced blizzard conditions in the Midwest and upper Great Lakes regions and strong winds along the U.S. northeast coast. There was a report of some snow with the heavy rain at Albany NY in a newspaper account. (x) 17th _ previous note: The timing issue does not affect this rainfall record substantially. The value is from the Tor A site. The Tor B site reported 23.8 mm plus 9.1 mm the next calendar day. It would appear that the Tor A amount of 33.0 mm may include that second portion but the author suspects that before 2003 the same observing protocols extending rainfall amounts to around 0700h next day were in place, so the data are at least comparable. The previous record of 0.58" (14.7 mm) was in 1929. ... The 2006 precip record was broken by the value recorded in the 2022 snowstorm now shown as the record. (x) For the Jan 29 2013 record, that one is preserved from Tor A data as the Tor B numbers while slightly smaller do not fall below the previous record nor do they suggest a timing issue. On Jan 21 2010 a record amount (22.4 mm) only appears in Tor A data, the event is not marked missing in Tor B but precip is zero. As YYZ , North York and City Centre (Island airport) also had zero and maps indicate no weather systems, this is regarded as spurious data and eliminated from my tables. However the reverse situation applies to Jan 24-25 with substantial rainfalls at the other locations and zero at Tor A. Therefore the totals are preserved and the same amount is shown on those dates instead, pro-rated as to amounts on each day by the same proportions as the nearby stations. It is possible that the record for 25th was broken in 2010 but as the amounts pro-rated were greater on 24th, the assigned amount falls short of the record there. This was the only apparent data entry error spotted in my exhaustive study other than one minor glitch with a November rain-snow combination discussed under November. --------------------------------------------------------------------------- <<< February Daily Precip Records >>> DATE __ Max rain _____ year ___ Max snow ___ year ___ Max precip ___ year___ Max 2d snow (year) __ notes Feb 01__1.08" (27.4 mm) 1968 ___9.8" (24.9 cm) 1908__ 1.08" (27.4 mm) 1968 __10.0" (25.4 cm) 1908 _ (a) Feb 02__1.57" (39.9 mm) 1842 ___6.6" (16.8 cm) 1967__ 1.57" (39.9 mm) 1842 __ 9.8" (24.9 cm) 1908 Feb 03__0.85" (21.6 mm) 1952 ___9.5" (24.1 cm) 1910__ 1.15" (29.2 mm) 1883 __14.5" (36.8 cm) 1910 _ (b) Feb 04__1.12" (28.4 mm) 2006 ___6.0" (15.2 cm) 1932__ 1.28" (32.4 mm) 2006 __ 9.6" (24.4 cm) 1910 _ (c)(x) Feb 05__1.01" (25.8 mm) 1938 __16.0" (40.6 cm) 1863__ 1.60" (40.6 mm) 1863 __17.0" (43.2 cm) 1863 Feb 06__1.44" (36.6 mm) 1897 __10.9" (27.7 cm) 1911__ 1.44" (36.6 mm) 1897 __18.0" (45.7 cm) 1863 _ 1843 psbl 20-30 cm snow Feb 07__0.61" (15.4 mm) 2017 ___8.0" (20.3 cm) 1861*_ 0.81" (20.6 mm) 1933 __11.2" (28.4 cm) 1887 _ (d) (x) Feb 08__1.02" (26.0 mm) 2001 ___7.0" (17.8 cm) 1903__ 1.55" (39.4 mm) 2001 __14.4" (36.5 cm) 2013 Feb 09__1.11" (28.1 mm) 2023 ___7.0" (17.8 cm) 1896__ 1.11" (28.1 mm) 2023 __ 7.1" (18.0 cm) 1903 _ (e) Feb 10__1.14" (29.0 mm) 1943 ___5.7" (14.5 cm) 1959__ 1.15" (29.2 mm) 1981 __ 7.5" (19.1 cm) 1896 _ (f) Feb 11__1.45" (36.8 mm) 2009 ___8.4" (21.4 cm) 1988__ 1.45" (36.8 mm) 2009 __ 8.6" (22.0 cm) 1988 _ (g) Feb 12__0.74" (18.8 mm) 1918 ___7.0" (17.8 cm) 2008__ 0.82" (20.9 mm) 2019 __ 9.8" (25.0 cm) 1988 _ (h) Feb 13__1.71" (43.4 mm) 1855___8.0" (20.3 cm) 1950__ 1.71" (43.4 mm) 1855 __ 8.2" (20.8 cm) 1894 Feb 14__0.80" (20.3 mm) 1949 __18.0" (45.7 cm) 1850__1.80" (45.7 mm) 1850 __18.0" (45.7 cm) 1850 Feb 15__1.62" (41.1 mm) 1857 __10.0" (25.4 cm) 1846__ 1.62" (41.1 mm) 1857 __18.0" (45.7 cm) 1850 Feb 16__0.74" (18.8 mm) 2006 ___9.3" (23.6 cm) 1954__ 1.21" (30.7 mm) 1954 __12.0" (30.5 cm) 1846 _ (x) Feb 17__0.94" (23.8 mm) 1998 __12.0" (30.5 cm) 1871__ 1.41" (35.8 mm) 2022 __12.1" (30.7 cm) 1871 _note Feb 18__0.60" (15.2 mm) 1842 ___9.0" (22.9 cm) 1860__ 0.90" (22.9 mm) 1860 __13.0" (33.0 cm) 1871 Feb 19__0.96" (24.4 mm) 1939 ___8.0" (20.3 cm) 1862__ 1.10" (27.9 mm) 1939 __ 9.0" (22.9 cm) 1860 Feb 20__0.90" (23.0 mm) 2014 __18.0" (45.7 cm) 1846__1.80" (45.7 mm) 1846 __18.0" (45.7 cm) 1846 _ (x) Feb 21__0.80" (20.3 mm) 1976* __11.0" (27.9 cm) 1950__1.10" (27.9 mm) 1950 __22.0" (55.9 cm) 1846 _ * (i) Feb 22__1.35" (34.2 mm) 1990 ___8.1" (20.6 cm) 1900__ 1.35" (34.4 mm) 1990 __14.2" (36.1 cm) 1950 _ (j) Feb 23__1.58" (40.1 mm) 1925 ___9.0" (22.9 cm) 1869__ 1.58" (40.1 mm) 1925 __12.0" (30.5 cm) 1869 Feb 24__1.17" (29.6 mm) 2016 __12.0" (30.5 cm) 1868__ 1.20" (30.6 mm) 2016*__13.0" (33.0 cm) 1868 _* (k) Feb 25__0.98" (24.9 mm) 1926 __13.0" (33.0 cm) 1960__ 2.07" (52.3 mm) 1932 __18.0" (45.7 cm) 1868 _ (L) Feb 26__0.75" (19.0 mm) 2013 ___7.8" (19.8 cm) 1946__ 1.54" (39.0 mm) 2013 __13.5" (34.3 cm) 1960 _ (m) Feb 27__0.84" (21.3 mm) 2013 ___7.0" (17.8 cm) 1873__ 1.01" (52.3 mm) 2013 __ 8.4" (21.3 cm) 1946 _ (m) Feb 28__0.77" (19.6 mm) 1902 __10.0" (25.4 cm) 1900__ 1.00" (25.4 mm) 1900 __14.3" (36.4 cm) 1984 _ (n) Feb 29__0.39" (9.9 mm) 1860 ____9.4" (23.9 cm) 1904__ 1.00" (25.4 mm) 1904 __ 9.6" (24.4 cm) 1984 ________________________________________________________________________ (a) A similar 2d snowfall total of 9.9" (25.0 cm) was reported Jan 31-Feb 1 2008, this one being more evenly distributed (5.4 cm plus 19.8 cm). Liquid equivalent for the entire event was 31.6 mm but the portion on Feb 1st was 19.4 mm. (b) The max precip from Feb 3, 1883 was from a combination of 8.0" snow and 0.35" rain (neither daily records). (c) Max precip Feb 4, 2006, boosted by 4.0 cm snow adding 4.0 mm l.e. to rainfall as shown. (x) The rainfall record is maintained as the Tor A data show very similar outcomes (29.8 mm total precip). The previous rainfall record had been 0.78" (19.8 mm) from 1842. Even with a slight reduction applied the 2006 value remains higher. (d) Snowfalls of 8.0" Feb 7, 1861 and 20.3 cm (as measured Feb 7, 2013) were tied after conversion. The 2013 snowmelt was also listed as 20.3 mm. This was part of a heavy two-day fall (see 2 day entry for 8th). Also, these snowfalls, while ahead of the maximum daily rainfall for precip, lost out to 1933 by .01" with a combined 0.47" rain and 3.4" snow. There had previously been a rainfall of 0.54" in 1914 so this was never a case of an augmented rainfall record being a precip record. Added later _ recently added historical weather maps extending back into the 1840s (wetterzentrale) now give me some basis for allocating Feb 1843 known total snowfall, and it appears that around 6th to 8th there was a promising situation for heavy snow especially on the 7th. The daily records listed may have been topped in 1843. (d-x) The Tor A - Tor B comparison shows very similar outcomes so no changes required here. (e) Two-day rainfall in 2001 Feb 8-9 reached 1.54" (39.2 mm) with an additional 0.52" (13.2 mm). In a three-day period, a total of 24.6 cm snow (7th-8th) followed by 39.2 mm rain (8th-9th) with 10:1 conversion used for the snow in this instance, amounted to 2.51" or 63.8 mm precipitation over three days. This was much of the 105 mm that fell in the month. New rainfall and precip records were set by 1.11" (28.1 mm) rain on 9th 2023, this broke records set in 1863 and 1894. former records were rain 0.63" (16.0 mm) 1863 ___ precip __ 0.90" (22.9 mm) 1894 On Feb 9 the (former record) maximum precip came from 1894 with 0.50" rain and 4.0" snow adding to .90" (22.9 mm). (f) Max precip from 1981 (1.15") just edged ahead of the rainfall derived value from 1943 (1.14"). The record value came from a combination of 17.2 mm rain and 10.0 cm snow with l.e. of 29.2 mm compared to the 29.0 mm derived from the conversion from the 1943 amount. Also there was a rainfall of 0.89" (22.7 mm) on same date in 1965. The author recalls this day as starting with freezing rain, then a milder rain followed by record warmth by the mid-day period (Feb 10 max 54 F 12 C). (g) Until the 1988 snowfall (precip 21.0 mm) the daily precip record had been 0.75" from 0.20" rain and 5.5" snow in 1887. Both of these were eclipsed by the heavier rainfall value in 2009. But until 1988, the 1887 record was the augmented value of the existing daily snowfall record. (g-x) The Tor A rainfall record of 1.45" (36.8 mm) compares to 25.6 mm from Tor A which has a further 7.6 mm on next day. That value of 25.6 mm would still be considerably ahead of the previous record of 0.73" (18.6 mm) from 1876. The two-day rainfall for Tor A, B remains similar (34-36 mm) ... this rainfall probably ended in the late overnight hours. (h) As discussed at various stages of the project, snowfall measurements since autumn 2017 have ceased to exist as anything beyond snow depth at the location as the site known as Tor A ceased to report daily rain and snow. Several possible record snowfalls are not entirely clear from the evidence available. On Feb 12, 2019, what I have to work with is a report of 20.9 mm, an increase in snow depth of 4 cm (by morning of 13th), highest temp 1.6 C, and nearest actual measurements from North York of 4.0 mm rain, 12.0 cm snow and precip of 20.2 mm. At Toronto City Centre (formerly Island A) a precip of 17 mm yielded a snow depth increase of 14 cm. From these clues I have assigned a snowfall of 10 cm for the Toronto (city) data base and 10 mm rain. Neither of these would be a daily record as shown but the combination is similar to the precip record. The snowfall was evidently at least partly melted before a snow depth was taken. (note 17th _ previous precip record 1.24" 1871. The 2022 amount of 1.41" consisted of 0.83" rain and 5.8" snow in a falling temperature transitional situation. Another 0.9" fell on the 18th. ) (i) The rainfall record on Feb 21st was tied in terms of conversion to inches -- 20.3 mm in 1976 and 20.2 mm in 1997 were both 0.80". Also, the 1997 rainfall was a two-day total (from 20th) of 1.39" (35.6 mm). (j) Despite adding 0.2 cm snow and 0.2 mm liquid, the conversion of 34.4 mm stayed in the range of 1.35" due to rounding. Meanwhile in 1922, there had been a heavy mixed fall of .69" rain and 6.1" snow (1.30") which was the precip record until 1990. The snowfall daily record from 1900 also had significant added rainfall (0.35") for a total precip value of 1.16" (29.5 mm). (k) The 30.5 mm precip equivalent from the 1868 record snowfall was edged out by 30.6 mm (also converts to 1.20") when the rainfall in 2016 was added to 1.4 cm snow (equivalent 1.0 mm). There was also a heavy rainfall in 1985 on this date (25 mm, 0.98"). The 2016 value is from Tor B but is unchallenged as Tor A had missing data, check of other locations confirms timing not an issue. (L) The record precip (for the month of Feb as well as 25th) came from a mixed snow, sleet and rain event (1965) that was recorded as 11.8" snow (30.0 cm), 0.25" rain (6.4 mm), 2.07" (52.6 mm) precip. The author measured mostly snow in this same event at a location 50 km west of Toronto (Georgetown, ON) and had 16.6" snow and just .01" rain observed briefly. The Toronto snowfall was in addition to 0.6" (1.5 cm) on 24th. (m) The record precip was based on 19.0 mm rain, 10.0 cm snow but 39.0 mm total liquid (26th 2013). The following day's total was also a combination, of 21.3 mm rain, 4.0 cm snow, and 25.7 mm liquid (1.01"). These are values from Tor B. The raw precip values from Tor A were 17.4 mm and 30.4 mm. Whatever the actual precise values, either location beats the older rainfall and/or precip records by a considerable margin. Feb 27, 1958 had a snow-freezing rain combination that gave a total of 0.81" -- one suspects that had this been in the later "liquid equivalent" era the values might have been higher. (n) The daily snowfall record was 10" (25.4 cm) in 1900 (28th) but 9.6" (24.4 cm) in 1984 added to an earlier fall on 27th to give a heavier total of 14.3". Although nothing further fell on 29th, that two-day total edged out the one-day total from 29th 1904. All snowfalls in 1984 reverted to the 10:1 method just for that one year in an otherwise liquid equivalent era 1963 to 2017. (It may have been the case that all of them were exactly 10:1 although that seems improbable). Because 1900 was not a leap year, a further 7.8" of snow on March 1st shows up there as the two-day record amount that would have fallen into Feb 29th otherwise. The smaller sample size for leap year day apparently caused the record rainfall to be unusually low although the record snowfall for the date does not vary from the trend established. (x) The record values earlier marked with (x) and another letter are discussed under that letter ... for Feb 16, the 2006 maximum rainfall is maintained as both Tor A and Tor B have similar values for the date (Tor A is shown, Tor B has 17.2 mm). (Feb 20) _ The value from TorA (23.0 mm) is used but even Tor B broke the existing record with 15.2 mm (0.60") still ahead of the previous mark, 0.48" from 2002. <<< March Daily Precip Records >>> DATE __ Max rain _____ year ___ Max snow ___ year __ Max precip __ year ____Max 2d snow (year) __ notes Mar 01__0.93" (23.9 mm) 1954 ___8.0" (20.3 cm) 1875__ 1.40" (35.6 mm) 1976 __17.8" (45.2 cm) 1900 _ (a) Mar 02__0.88" (22.4 mm) 1854 ___5.5" (14.0 cm) 1948__ 1.07" (27.2 mm) 1976 __ 9.5" (24.2 cm) 1976 _ (a) Mar 03__0.93" (23.9 mm) 1953 ___8.0" (20.3 cm) 1875__ 1.00" (25.4 mm) 1862 __ 8.0" (20.3 cm) 1875 _ (b) Mar 04__1.19" (30.2 mm) 1974 ___8.0" (20.4 cm) 1985*_ 1.54" (39.1 mm) 1985 __11.9" (30.0 cm) 1985 _ (c) Mar 05__0.68" (17.3 mm) 1899 ___8.9" (22.6 cm) 1917__ 0.94" (23.9 mm) 1851 __10.3" (26.2 cm) 2001 _ (d) Mar 06__1.44" (36.6 mm) 1900 ___8.0" (20.3 cm) 1943__ 1.44" (36.6 mm) 1900 __ 9.0" (22.9 cm) 1943 Mar 07__0.91" (23.0 mm) 2009 ___5.4" (13.7 cm) 1975__ 0.91" (23.0 mm) 2009 __ 9.1" (23.0 cm) 1923 _ (x) Mar 08__0.93" (23.6 mm) 1942,98_12.5" (31.8 cm) 1931__ 1.25" (31.8 mm) 1931 _12.5" (31.8 cm) 1931 _ (e) Mar 09__0.69" (17.5 mm) 1854 ___5.9" (15.0 cm) 1994__ 0.69" (17.5 mm) 1854 __15.5" (39.4 cm) 1931 Mar 10__0.99" (25.1 mm) 2011 __11.7" (29.7 cm) 1949__ 1.17" (29.7 mm) 1949 __12.0" (30.5 cm) 1949 Mar 11__1.06" (26.9 mm) 1936 ___7.9" (20.0 cm) 1941__ 1.15" (29.2 mm) 1871 __11.7" (29.7 cm) 1949 _ (f) Mar 12__1.18" (30.0 mm) 1977 ___8.6" (21.8 cm) 1968__ 1.18" (30.0 mm) 1977 __ 8.6" (21.8 cm) 1968 _ (g) Mar 13__0.85" (21.7 mm) 1852,2010 __9.0" (22.9 cm) 1870_ 1.03" (26.2 mm) 2010 _15.0" (38.1 cm) 1870 _ (h) Mar 14__0.94" (23.9 mm) 1973 ___6.6" (16.8 cm) 1951__ 0.94" (23.9 mm) 1973 __ 9.0" (22.9 cm) 1870 Mar 15__0.95" (24.1 mm) 1899 __10.0" (25.4 cm) 1870__ 1.05" (26.7 mm) 1862 __10.0" (25.4 cm) 1870 _ (i) Mar 16__1.45" (36.8 mm) 1942 __10.0" (25.4 cm) 1870__ 1.45" (36.8 mm) 1942 __20.0" (50.8 cm) 1870 Mar 17__0.96" (24.4 mm) 1919 __10.0" (25.4 cm) 1936__ 1.48" (37.6 mm) 1973 __13.0" (33.0 cm) 1936 _ (j) Mar 18__1.62" (41.1 mm) 1859 ___4.7" (11.9 cm) 1977__ 1.63" (41.3 mm) 1859 __10.0" (25.4 cm) 1936 Mar 19__1.72" (43.7 mm) 1881___8.5" (21.6 cm) 1883__ 1.72" (43.7 mm) 1881 __12.5" (31.8 cm) 1883 Mar 20__0.72" (18.3 mm) 1848, 1980 _9.0" (22.9 cm) 1862,76_0.90" (22.9 mm) 1862,76_9.0" (22.9 cm) 1862,76 (s) Mar 21__1.13" (28.7 mm) 1849 __15.0" (38.1 cm) 1867__ 1.50" (38.1 mm) 1867 __15.5" (39.4 cm) 1876 Mar 22__0.54" (13.7 mm) 1975 ___3.9" (9.9 cm) 2024^___ 0.50" (12.7 mm) 1949 __16.5" (38.1 cm) 1867 _ (x) Mar 23__0.75" (19.0 mm) 2022 __6.2" (15.8 cm) 1883__ 0.77" (19.5 mm) 2022 __ 6.4" (16.3 cm) 1883 _ (note) Mar 24__1.55" (39.4 mm) 1842 ___3.6" (9.2 cm) 1856___ 1.55" (39.4 mm) 1842 __ 6.2" (15.8 cm) 1883 Mar 25__0.95" (24.1 mm) 1930 ___4.8" (12.2 cm) 1955__ 1.40" (35.6 mm) 1930 __ 6.3" (16.1 cm) 1930 Mar 26__1.22" (30.9 mm) 1877 ___9.7" (24.6 cm) 1873__ 1.22" (30.9 mm) 1877 __11.7" (29.7 cm) 1873 Mar 27__0.90" (23.0 mm) 1991 __16.0" (40.6 cm) 1870__1.60" (40.6 mm) 1870 __19.5" (49.5 cm) 1870 _ 9.2" 2d sn1934 Mar 28__1.13" (28.7 mm) 1878 __10.5" (26.7 cm) 1876__ 1.13" (28.7 mm) 1878 __16.5" (41.9 cm) 1870 Mar 29__0.76" (19.4 mm) 2009*___5.7" (14.5 cm) 1876__ 0.76" (19.4 mm) 2009 __16.2" (41.2 cm) 1876 _ * (k) Mar 30__1.10" (27.9 mm) 2019 ___8.5" (21.6 cm) 1922__ 1.40" (35.6 mm) 1922 __ 8.5" (21.6 cm) 1922 _ (L) Mar 31__1.20" (30.5 mm) 1945 ___6.0" (15.2 cm) 1889__ 1.30" (33.0 mm) 1926 __ 9.6" (24.4 cm) 1987 _ (m) __________________________________________________________________________ Notes: (a) March 1st 1976 managed 35.6 mm precip from 17.8 cm snow. The previous mark was from 1954 when the rainfall record was set along with 4.1" snow for 1.34" of precip. Also on March 2nd, 6.4 cm of snow with 0.3 mm rain produced 27.2 mm precip for the daily record. This two-day storm was a prolonged mixture of snow, ice and snow pellets, sleet and some rain that changed to light rain in Toronto by 3rd but continued as heavy mixtures in central Ontario for several more days; when this melted in warmer weather mid-March 1976, there was extensive flooding. Another heavy mixture fell on March 1st 2007 (.52" rain, 4.2" snow, gave 1.17" precip). (b) The max precip on March 3rd came from a mixture of 0.70" rain and 3.0" snow (1.00" or 25.4 mm) in 1862. (c) The Mar 4 snowfall record of 20.4 cm (1985) converts to the same value (0.80") as the previous record measured in inches (1881 - 8.0"). The 1985 snowfall was accompanied by 8.1 mm rain, the total precip was 39.1 mm to ensure a daily record, by the previous 10:1 method the total would have been less than the 1974 rainfall. (d) The Mar 5 precip record came from a mixture of 0.64" (16.3 mm) rain and 3.0" (7.6 cm) snow in 1851. (e) The Mar 8 rainfall records from 1942 and 1998 both have same value despite different measurement systems in place (0.93" as measured in 1942 converts to 23.6 mm as measured in 1998). (f) The Mar 11 precip record was a combination of 1.05" rain (.01" under the eventual record) and 1.0" snow in 1871. (g) The Mar 12 max snowfall in 1968 continued briefly into 13th and amounted to 12.1" (30.7 cm) for a two-day total but that was not enough to displace the competing two-day value from 1870 on 13th. The amount on the 12th did displace the first day portion of that event which had been 6.0" (in 1870). (h) The 1852 record was measured as 0.85" which converts to 21.6 mm. The 2010 tie was measured at 21.7 mm which converts to 0.85" for the tie. The Tor A station normally used in winter months had more than this (26.2 mm) but was not selected for use in March 2010 because the month had zero snowfall. (i) Precip record on Mar 15 was achieved with 0.75" rain and 3.0" snow (1862). (j) Precip record on Mar 17 1973 from 0.94" (23.9 mm) rain and 5.4" (13.7 cm) snow. Rain from 16th of 0.59" (15 mm) made this a two-day rainfall of 1.53" (38.9 mm). This storm caused a major traffic accident north of Toronto in heavy snow squalls. (k) Rainfall record of 20.4 mm in 2009 ties in terms of imperial conversion to 0.80" (which converts to 20.3 mm) in 1902. This also applies to the max precip value for 29th. The 2009 rainfall was a two-day event 28th-29th totalling 32.6 mm (1.28"). Also, see note (x) added below, this event only shows up on 29th for Tor A which had 23.9 mm on 29th. This makes it appear that the "two-day event" from Tor B was all on the calendar date. So the record is either the 32.6 mm two-day total or the 23.9 mm one-day total from Tor A. By either station's measurement, the daily record was set in 2009. (L) The rainfall of 1.10" (2019) is the bulk of precip reported as 1.24" with a slight snow accumulation (being 2019 there was no direct snow measurement). Comparison to North York showed that snowfall was probably about 1-2" so the precip is arbitrarily divided into 1.10" rain and 1.4" snow. The previous record had been 0.85" rain in 1951. In any case the 2019 event was not max precip as the heavy snow on Mar 30, 1922 (8.5") combined with 0.55" rain for a total of 1.40". (m) The max precip from 1926 occurred when 1.00" of rain combined with 3.0" of snow. The 1987 snowfall event was a three-day total (March 30-April 1) of 11.2" (28.4 cm) -- this storm was the trailing edge of an even heavier snowstorm that hit parts of New England. (s) _ added later _ The maximum rainfall of 0.72" in 1848 was tied by conversion of 18.2 mm 1980, however, the metric conversion of 0.72" is 18.3 mm. _ (note Mar 23) _ rainfall record and precip record broken in 2022, mostly rain (19.0 mm) with 0.5 cm snow est in 19.5 mm precip, the previous records were Mar 23__0.49" (12.4 mm) 1926, 2010 and 0.62" (15.8 mm) 1883 (this from snowfall record). (x) An issue was noted after this table was completed. Station "Tor B" that includes daily temperatures and precip only (July 2003-end of data) has a report of only 17.9 mm for the same date (2009). This did not break the existing record of 0.77" (1868). My procedure has been to take any data available from Tor A since they had identified snowfall amounts. Tor A only reported during the snowfall season, so no overlap issues for most rainfall records, only Tor B was available for those months. ... All other 2003-2017 rainfall records are being cross-checked to see if they qualify from both locations. As noted below (April 6 note) Tor A also appears to be reporting amounts from 0800h to 0800h (with reports filed on date of that starting time) so there can be cases where part of a calendar day rain or snow is on the previous day's Tor A report. At this point I can see no way to disentangle the snowfall timing in the few cases where it might affect a record (and the two-day totals are more likely to be unaffected). But for the rainfall maxima that are subject to two reports, each one will receive a qualifying note similar to this one if there is any appreciable difference to the outcome. (Mar 22-23) _ Some doubt exists about the daily rainfall record from Tor A (0.57" 2010) as Tor B has only 3.0 mm on that date and 12.5 mm on 23rd (which ties 1926 for that daily record). This suggests the heavier Tor A rainfall fell largely after midnight. The record before 2010 for March 22nd was only 0.54" (13.7 mm) from 1975. On this basis that 1975 record is used for this summary. In most Marches from 2003 to 2017, Tor A was used for precip but because Tor A reported zero snowfall in March 2010, I went over to Tor B as I usually would do in April of other years. It is also worth noting that the rainfall records for Mar 22-23 are among the lowest of the entire calendar year. A few days in late January match them. (2022 later broke low value). ^ 2024 snowfall record for mar 22 (3.9" 9.9 cm) broke 2.9" (7.1 cm) 1879. Storm total and snow on ground 10.0 cm. Despite confusion about different time intervals 2003-17 for two reporting locations (or systems), Toronto City now appears to be reporting on calendar day basis or at least 06z to 06z as mar 22-23 snowfall ends at 0200 (EDT) of mar 23 (06z) ========================================================= <<< April Daily Precip Records >>> DATE __ Max rain _____ year ___ Max snow ___ year __ Max precip __ year ____Max 2d snow (year) __ notes Apr 01__0.67" (16.9 mm) 2023 ___6.0" (15.2 cm) 1861__ 0.67" (16.9 mm) 2023 __ 7.8" (19.8 cm) 1987 _ (note) Apr 02__0.94" (23.8 mm) 2005 ___5.3" (13.5 cm) 1975__ 1.36" (34.2 mm) 2005 __ 6.0" (15.2 cm) 1861 _ (a) Apr 03__2.35" (59.7 mm) 1850___4.1" (10.4 cm) 1975__ 2.35" (59.7 mm) 1850 __ 9.4" (23.9 cm) 1975 _ (a) (x) Apr 04__1.22" (31.0 mm) 1984 ___4.7" (12.0 cm) 1979__ 1.22" (31.0 mm) 1984 __ 5.4" (13.6 cm) 1996 Apr 05__1.82" (46.2 mm) 1929 ___8.0" (20.3 cm) 1852__ 1.82" (46.2 mm) 1929 __ 8.0" (20.3 cm) 1852 Apr 06__1.06" (26.9 mm) 2017 ___5.5" (14.0 cm) 1886__ 1.06" (26.9 mm) 2017 __ 8.5" (21.6 cm) 1852 _ (b) Apr 07__1.22" (31.0 mm) 1893 ___6.4" (16.3 cm) 1967__ 1.25" (31.7 mm) 1893 __ 7.4" (16.3 cm) 1886 Apr 08__1.52" (38.6 mm) 1991 ___7.5" (19.0 cm) 1979__ 1.52" (38.6 mm) 1991 __ 7.5" (19.0 cm) 1979 Apr 09__1.28" (32.5 mm) 1864 ___4.1" (10.5 cm) 1897__ 1.28" (32.5 mm) 1864 __ 9.1" (23.2 cm) 1979 Apr 10__1.15" (29.2 mm) 1859 ___7.0" (17.8 cm) 1943__ 1.15" (29.2 mm) 1859 __ 7.0" (17.8 cm) 1943 Apr 11__1.61" (40.9 mm) 1922 ___4.0" (10.2 cm) 1940,44_ 1.61" (40.9 mm) 1922__ 7.1" (18.1 cm) 1894,1943 Apr 12__1.84" (46.7 mm) 1951 ___4.7" (11.9 cm) 1932__ 1.84" (46.7 mm) 1951 __ 4.7" (11.9 cm) 1932 Apr 13__0.85" (21.6 mm) 1979 __ 1.5" (3.8 cm) 1864,1962_0.85" (21.6 mm) 1979__ 6.1" (15.5 cm) 1932 Apr 14__1.78" (45.2 mm) 1903 ___2.0" (5.1 cm) 2018 ___1.78" (45.2 mm) 1903 __ 2.0" (5.1 cm) 2018 _ (c) Apr 15__1.37" (34.8 mm) 1954 ___5.5" (14.0 cm) 1893__ 1.43" (36.1 mm) 2018 __ 5.5" (14.0 cm) 1893 _ (c) Apr 16__1.31" (33.4 mm) 1992*___3.4" (8.6 cm) 1943 ___1.31" (33.4 mm) 1992*__ 5.5" (14.0 cm) 1893 _ *(d) Apr 17__1.13" (28.7 mm) 1939 ___4.0" (10.2 cm) 1965__ 1.13" (28.7 mm) 1939 __ 4.0" (10.2 cm) 1965 Apr 18__1.49" (37.8 mm) 1869 ___2.0" (5.0 cm) 2022*___ 1.49" (37.8 mm) 1869 __ 4.0" (10.2 cm) 1965 _*(e) Apr 19__1.16" (29.3 mm) 1963 ___1.8" (4.6 cm) 1857___ 1.16" (29.3 mm) 1963 __ 1.8" ( 4.6 cm) 1857 Apr 20__1.82" (46.2 mm) 1893 ___8.3" (21.1 cm) 1901__ 1.82" (46.2 mm) 1893 __ 8.3" (21.1 cm) 1901 _ (f) Apr 21__1.56" (39.6 mm) 1862 ___4.7" (11.9 cm) 1928__ 1.56" (39.6 mm) 1862 __ 8.3" (21.1 cm) 1901 _ (f) Apr 22__1.12" (28.4 mm) 1977 ___3.5" (8.9 cm) 1867___ 1.12" (28.4 mm) 1977 __ 3.5" ( 8.9 cm) 1867 _ (g) Apr 23__1.08" (27.4 mm) 1866 ___3.0" (7.6 cm) 1963__ 1.08" (27.4 mm) 1866 __ 3.5" ( 8.9 cm) 1867 _ (h) Apr 24__0.86" (21.8 mm) 1886 ___1.3" ( 3.3 cm) 1875__ 0.86" (21.8 mm) 1886 __ 3.0" ( 7.6 cm) 1963 Apr 25__1.42" (36.1 mm) 1842 ___4.0" (10.2 cm) 1976__ 1.42" (36.1 mm) 1842 __ 4.0" (10.2 cm) 1976 _ (i) Apr 26__1.25" (31.8 mm) 1885 ___2.0" ( 5.1 cm) 1854__ 1.25" (31.8 mm) 1855 __ 4.0" (10.2 cm) 1976 Apr 27__1.03" (26.2 mm) 1871 ___0.8" ( 2.0 cm) 1966__ 1.03" (26.2 mm) 1871 __ 2.5" ( 6.4 cm) 1854 (2.2" 1966) Apr 28__1.60" (40.6 mm) 1866 ___0.8" ( 2.0 cm) 1885__ 1.60" (40.6 mm) 1866 __ 0.8" ( 2.0 cm) 1885,1966 Apr 29__1.26" (32.0 mm) 2014 ___3.4" ( 8.6 cm) 1909__ 1.26" (32.0 mm) 2014 __ 3.4" ( 8.6 cm) 1909 _ (j) Apr 30__1.31" (33.3 mm) 1845 ___2.5" ( 6.4 cm) 1908__ 1.31" (33.3 mm) 1845 __ 3.4" ( 8.6 cm) 1909 _ (k) _____________________________________________________________ Notes: (1st) _ 2023 broke records set in 1929, 0.62" rain and 0.63" prec (0.62R + 0.1S) (3rd) _ 2024 rainfall of 56.6 mm would have been a daily record on any other date in April, but fell short of the 1850 daily and April record of 59.7 mm. A 2d total of 64.2 mm 2nd-3rd was an April record. (a) The snowstorm of April 2-3, 1975 was much heavier in some areas north of Toronto where 60 to 80 cm fell over three days into April 4 (Toronto added 0.2" or 0.5 cm then). The storm had some intervals of rain and sleet in Toronto that did not occur further north, where very strong northwest winds during and after the storm drifted snow to considerable heights in Simcoe County and stranded road travelers in emergency shelters for up to five days. The author was living in that region during the storm and was confined to home as the nearby roads kept drifting over and with the strong April sun (after April 4) an arctic-like daily freeze-thaw cycle cemented snow drifts in place for up to ten days. This was definitely a "singularity" and while snowfall numbers in the 2005 event look similar, it had no similar impacts further north. The last of the storm's snow melted around April 19th in the region, ice persisted on local lakes to May 2nd then the entire month of May was hot and dry in contrast to the very cool April (see rankings). In 2005, the same two days produced a total of 19.4 cm along with 33.2 mm of rain, but the snow depths reported never changed from trace amounts. April 2, 2005 was as close as any other day (after Jan 1, 1932) came to setting both rain and snow records (ended up second in snowfall and first in rainfall). note also Apr 2 05 precip 29.8 mm from Tor B. (b) As noted earlier in study, two sets of precip records exist after 2003. The station identified as "Tor B" or Toronto City picked up the temperatures after July 2003. The other location "Tor A" (Toronto) continued to record only precip including rain and snow. This location only reported during the snowfall seasons from 2003-04 to 2016-17. Therefore the author has had to take rainfall data from Tor B for the summer half of the year. In the case of April 6, 2017, Tor B gives us 26.9 mm for a record amount. Tor A provides a similar 2d total of 27.8 mm but most of it is shown on April 5. This leads me to conclude that Tor A measurements took place around 0800h while Tor B runs a calendar day measurement. Also the fairly close Toronto airport (YYZ) location has all of this rainfall event on April 6 (27.8 mm + 0.4 cm snow) and they certainly report their measurements to calendar days. (c) Snowfall April 14-16 2018 during a prolonged spell of mixed precipitation (also rain, sleet, ice pellets) is estimated from snow depth shown as 4 cm by morning 15th and 5 cm morning 16th then 4 cm morning 17th (only Tor A reports exist by this time, Tor B ceased its reports after winter 2016-17). Another clue is reported snowfalls at North York which are 7.6 cm (14th) and 3.2 cm (15th). Snow depths were given as 7 cm after each day. Similar precip values are also reported. Further out of the city, the YYZ location reported 4.2 cm and 3.8 cm with less overall precip (influence of Lake Ontario evident). The author also knows of some weather forum reports supporting 5-10 cm amounts on these dates. Otherwise, the daily record for April 14 would be 1.1" from 2014. The record for the 15th (1893 5.5") was not challenged. Over three days (April 14-16) a total of 89.3 mm precip fell. The precip record for the 15th (1.43") had estimated components of 1.23" rain and 2.0" snow. This edged out the all-rain value from 1954 of 1.37". (d) The maximum rainfall in 1992 (33.4 mm) converted to the measured value of 1.31" also posted on Apr 16th in 1919. That however converts to 33.3 mm in metric, so it's a case of a statistical tie for the imperial measurement. This also applies to the precip as neither of these days had any accompanying snowfall. Also of note on April 16, a second place two-day snowfall of 3.5" from both 1904 and 1947. (e) New daily record 2022 is from estimated value comparing to results measured at YYZ. The actual amount could have been in the range of 5-15 cm and after melting snow on ground was not persistent to next morning (the snow occurred during the evening with temperatures near 1 C). The previous record is 1.5" (3.8 cm) 1947. (f) The heavy snowfall event on Apr 20 1901 was accompanied by heavy rainfall, 0.56" fell on 20th and 0.90" more on Apr 21. The cause was a nearly stationary stacked low in the mid-Atlantic states. No further snow fell but it rained less heavily for three more days before clearing up. The maximum temperature reported on 20th was 38 F (3.3 C), somewhat milder air worked its way into the easterly flow by the next day (52 F). The precip for the day (20th) of 1.39" might have been reported as a heavier amount in the modern protocols but fell short of the all-rain value of 1.82" (1893). ... A snowfall of 1.5" (3.8 cm) on 20th in 1857 completed a two-day value of 3.3" (8.5 cm) that was eclipsed by this one-day snowfall event. The next day, the snowfall record from 1928 was nearly matched by 4.3" on 21st in 1945. (g) A further 0.80" (20.3 mm) rain on Apr 23 1977 brought the two-day total to 1.92" (48.8 mm). (h) Two day rainfall of 1.83" (46.5 mm) in 1847, on 22nd .76" was the maximum until broken by 1977 and on 23rd the amount was 1.07" just .01" below the record value in 1866. (i) The snowfall of 4.0" (10.2 cm) on Apr 25, 1976 was as heavy as 20 cm further north (part of this event at Toronto was rainfall of 0.56" (14.2 mm) on 24th and 0.20" (5.1 mm) on 25th. Precip on 25th was consistent with 10:1 ratios and snow depth reported next morning was 5 cms. As it had turned very warm a week earlier (record highs on several days 16th-19th) deciduous trees had come out into full spring foliage and the heavy wet snow caused many large branches to fall off. It had been near 80 deg F for several days a week earlier. Tree foliation was very rapid in both April 1976 and 1977. By contrast, in both 1966 and 1967 full spring foliation was not observed until late May. (j) Maximum rainfall for Apr 29, 2014 is from Tor B as Tor A had stopped reporting for the winter season two weeks earlier anyway. This new record only edged out 1.16" from 1921 previous record. This will be the last note about rainfalls 2003-2017 until we reach the November records when the two-station situation comes into play again. The practice of terminating the Tor A reports in April means that any snow that might have fallen in May (and same applies to October) can only be deduced indirectly from other local reports. See the May summary for any findings, the monthly precip values all show zero snowfall for May after 2001's trace amount. (k) Another significant snowfall on Apr 30 was 2.0" (5.1 cm) in 1963 which combined with 0.64" rain. This snow continued into May 1st when another 0.7" was recorded (2.7" total but 3.0" fell on May 1, 1875). (x) A separate precip issue for April 3 arises from unusual readings of a relatively small snowfall of 10 cm reported as 40 mm of precip at the newly established (July 2002) parallel "Tor B" station Toronto City (at that time the "Tor A" station continuing on from the longer data set under the name Toronto still had temperature data, slightly at variance with the data shown for Tor B although that too could be partly due to a time of observation issue. The Tor B station has only precip at this point and shows 22.2 mm on 3rd, 13.5 mm on 4th with 6 cm new snow on ground. This leads me to conclude that the heavy sleety snowfall event with the large additional (non-rain-reported) precip was overnight to some extent. In any case, the month's heaviest rainfall (Apr 3, 1850) prevented even the inflated 40 mm precip amount from qualifying as max precip although it might have done so on about half the days in April. ... In part because I also find this very confusing, this is the sequence of events established by the gradual change of observing practices at the general location of the Toronto downtown weather station. (1) mid-2002 : a second location (Toronto City) begins a parallel set of obs with temps and precip but no snowfall. ... I also refer to this location as Tor B. (2) Toronto (the station with data since 1840) continued its full reporting to June 2003. This is "Tor A" in any discussions in these notes. Tor A (Toronto) then dropped temperatures and snowfall which from that point on (July 1, 2003) only appeared with Toronto City (what I also call Tor B). (3) Tor A finally went silent entirely after winter 2016-17, and reported only during the snowfall months from 2003 to 2017. (4) Tor A changed their observation day some time around the split, if not before (an issue I hope to resolve with EC) to what appears to be 0800h-0800h so that if any rainfall event continues overnight, almost all of it falls into one day's report, whereas Tor B reports closer to a calendar day format (could be 0100-2400 local hourlies combined). (5) All of the rainfall records since 2003 are either from Tor A records where snow daily measurements were active, otherwise Tor B (Toronto City) . I considered the issue of having calendar day records for precip but could not be sure that calendar day had been the standard before 2003 for various intervals (including much of the deeper historical record). It is believed by the author that some if not most of the pre-2003 Toronto data were calendar day records but there was probably more adherence to this around the 1940s to 1960s than at other times (because at those times Toronto was a first-order reporting station with more frequent observer measurements) . By calendar day there could be routines such as 0100-2400 local hourly obs, midnight to midnight or 06z to 06z (Toronto is in the eastern time zone, in standard time 06z is 0100h local, in EDST it is 0200h local). These details would not skew the comparison of daily values very much but stretching the day to 0800h does make it "apples and oranges" to the extent that it matters to the non-purist. TOR A (identified as Toronto with navigation available to 1840) ceased operation April 27, 2017 and did not reappear in winter 2017-18 or thereafter. TOR B (identified as Toronto City) continued to the present and can be scrolled back to mid-2002 when it appeared as a full alternative to the existing Toronto. I have only used it since Tor A appeared in mid-2003. As an example of how these two locations display two different reporting days near the end of their overlap, on April 19-20, an apparently overnight rainfall event shows up this way: Date ____________ Tor A ___ Tor B ___ YYZ ____ North York Apr 19 2017 _____19.6 _____ 1.2 _______ 0.6 ______ 0.4 Apr 20 2017 _____ 5.4 _____ 23.3 _____25.0 _____18.4 From that example, one can see that Tor A (the snowfall-precip only alternative) is recording amounts during the next calendar day while Tor B and YYZ are recording totals around midnight. I added North York which is apparently also a "calendar day" reporting station. Currently some work is underway to ensure that daily rainfall records are always from Tor B during the overlap, and some consideration is being given to adjusting calendar day snowfalls which from 2003 to 2017 are shifted into the overnight reporting mode. An issue yet to be addressed is whether any parts of the 1840 to 2003 reporting were similarly offset. (note: often in April and sometimes in either Oct or Nov, one snowfall is preserved from Tor A which has an incomplete monthly log and the procedure here was to take the Tor B precip and change the appropriate portion to snow on a 10:1 basis or by some blending of the data if a different liquid equivalent seemed to be confirmed from the partial Tor A records. Some further small (usually trace) snowfalls were detected from comparison with North York nearby). Link to comment Share on other sites More sharing options...
Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 The format follows the posts above (see preamble two posts back for general details) Since snowfall is limited in May, the max 2-day snow feature is now dropped until November. Every two-day total that is more than just an isolated one-day event can be inferred from the daily records. Two cases that are actual hidden two-day totals are explained in notes. This post will cover May, then June to August in parallel formats since there is only rainfall to track there (and rainfall = precip). This leaves some additional space for notes beside instead of below the text, and that space will be used to track two-day events and also some notable tropical system causes of the record rainfalls where known. In that format, for any given year, "H8" as an example means Hurricane number 8 but implies a post-tropical phase of that system by the time its remnants reach Toronto. After 1950 hurricanes are named so one might encounter for example "1957 H Audrey" (June 28 1957). In each case what is implied is that the circulation of the former hurricane or tropical storm reached the lower Great Lakes and created the rainfall that reached daily record status. You may be quite impressed with the number of cases that show up from August to October, the number in July and July will be relatively small. The author has checked a number of other rainfall events against archived maps (wetterzentrale 1836-2015) and makes a few notes of the types of systems that produced some of the non-tropical-remnant events. The main choices there are frontal wave (passing near or south of Toronto), warm front or cold front, or overhead closed low. Notes will only expand to space below the data tables where necessary for completion. Although every May precip record is now the daily rainfall record, that was not the case on May 1st until 2017 when a rainfall of 0.92" eclipsed the mark set in 1875 from a combined 0.60" rain and 3.0" snow (the largest in May) for 0.90" -- that had been ahead of the existing rainfall record of 0.81" from 1869. As a result, there is no need to list daily precip records for May, they are all the same as the daily rainfall records now. In no case did any of them augment any amount from combined snow although some had traces of snow or measured snow the following day. Leaving out the daily precip for May leaves space for June parallel to May. For June, no snow was reported except for traces on June 1, 1945 and June 3 and 4 of 1859. <<< May Daily Precip Records >>> - - - - - - - - - - - - - - - - - - - - - - <<< June Daily Precip Records >>> DATE __ Max rain (precip)_year___Max snow___year __notes __________ DATE _ Max rain and precip _ year __ notes May 01__0.92" (23.3 mm) 2017 ___3.0" (7.6 cm) 1875__________________Jun 01 __ 1.79" (45.5 mm) 2012 _ Tr snow 1945 May 02__1.55" (39.4 mm) 1992 ___0.6" (1.5 cm) 1909_2d sn 3.1" (7.8 cm) 1875_Jun 02__ 1.20" (30.5 mm) 1947 _ (f) May 03__0.95" (24.2 mm) 1984 ___0.2" (0.5 cm) 1911__________________Jun 03 __ 1.36" (34.5 mm) 1882 _ Tr snow 1859 May 04__1.50" (38.1 mm) 1871 ___1.5" (3.8 cm) 1907__________________Jun 04 __ 0.89" (22.6 mm) 1869 _ Tr snow 1859 May 05__1.41" (35.8 mm) 1868 ___0.3" (0.8 cm) 1891__________________Jun 05 __ 1.51" (38.4 mm) 1885 _ low south May 06__1.85" (47.0 mm) 1861 ___Trace (Tr cm) 1976,89 ______________ Jun 06 __ 1.08" (27.4 mm) 1931 May 07__1.58" (40.1 mm) 1960 ___0.3" (0.8 cm) 1855__________________Jun 07 __ 1.25" (31.7 mm) 2022* May 08__0.94" (23.9 mm) 1860 ___0.6" (1.5 cm) 1855_ 2d r 2.48" (63.0 mm) 1960_Jun 08__1.61" (40.8 mm) 1906 May 09__1.09" (27.7 mm) 1956 ___1.3" (3.3 cm) 1923 (0.4" 1.0 cm 2020) _Jun 09 __ 1.37" (34.8 mm) 1922 May 10__1.24" (31.5 mm) 1841 ___0.2" (0.5 cm) 1923 _________________ Jun 10 __ 1.55" (39.4 mm) 1872 _ fr wave May 11__1.59" (40.4 mm) 1858 ___Trace (Tr cm) 1938, 2020 (2.8 cm YYZ) _Jun 11 __ 2.36" (59.9 mm) 1870 _ stat front s May 12__2.67" (67.8 mm) 2000 ___0.5" (1.2 cm) 1966 _ (a) _____________Jun 12 __ 1.97" (50.1 mm) 2023 ^ May 13__2.22" (56.4 mm) 1868 ___0.1" (0.3 cm) 1912 _R 1868 deep low south Jun 13 __ 1.63" (41.4 mm) 1996 _ (g) May 14__0.91" (23.2 mm) 1929 ___Trace (Tr cm) 1959, 2016 (North York) _ Jun 14 __ 1.28" (32.5 mm) 1926 May 15__2.04" (51.8 mm) 1942 ___ 0.2" (0.5 cm) 1959 _R 1942 frontal trof _ Jun 15 __ 1.80" (45.7 mm) 1879 _ warm front May 16__2.33" (59.2 mm) 1893 ___ 0.1" (0.3 cm) 1884 _R 1893 deep low s.e.

Local rainfalls up to 150 mm (6") reported. The cause was a slow-moving frontal wave separating warm, humid air to south from cool, moist air over Toronto to Lake Huron region. (b) Note applies to previous day (May 16) _ Another very heavy rainfall occurred in 1974 _ 2.31" (58.7 mm) and including previous day 2.56" (65.1 mm). This rainfall caused severe flooding on the Grand River in southwestern Ontario. Also note that while May 16th has the season's last measurable snowfall, May 17th is the first snow-free day with not even a trace amount in the records. The last trace of snow was June 4th in 1859. (c) The three-day record-breaking rainstorm May 19-21 1894 dropped 5.80" (147.3 mm) and is the only time that three consecutive days set rainfall records. The cause was a nearly stationary inverted trough feature over the mountains of PA and NY state with Toronto on the west side of the moisture-laden system. The first of the three records was approached in 1972 (1.20") and the second one in 1996 (1.75"). The third day of this wet spell set the daily record for May almost equalled in 2000 on May 12th. A similar three-day rainfall in September 1878 (11th-13th) of tropical origins dropped 4.83" (122.2 mm) in a similar progression but only the last of these days set a daily record. From September 13 to 15 of 1843, 5.18" (136.7 mm) fell but the first of these was only 0.20" (5.1 mm) so it was essentially a heavy two-day event and also the rainfall record was set in the middle of the three day interval in that case. These three rainstorms combined for almost as much rain as fell in all of the driest year (1874) as ranked previously. (d) May 21-22 2001 had a two day total of 3.08". (e) Although no snow trace was reported at Toronto downtown, on the early morning of May 26 1961 YYZ (Toronto airport) had several hours of mixed rain and snow that was reported as 0.2" (0.5 cm) (for some reason it appears on the 25th in the daily weather although both temps and hourly obs were only consistent with snow from 02-04h LST). This was the latest known measurable snowfall at any Toronto recording site until May 28, 2021. (f) Trace of snow at downtown location is based on video evidence of snow mixing with rain during the day, temp around 7-9 C, no accumulation on the ground ... but 0.2 cm reported at YYZ, their latest measurable snowfall ... amounts of 3-5 cm reported in some higher areas of southwestern and south central Ontario, highest being at around 500-600 meters a.s.l. south of Georgian Bay. (f) From May 29 to 31 of 1889, a total of 1.96" rain fell (49.8 mm). The heaviest daily amount was 24.1 mm (0.95") on the 30th. This was the heavy rain event that created the Johnstown PA flood disaster on May 31 when a dam broke and inundated the town and nearby valley, with a death toll of 2,200 or more. Also on May 31, in 1985, an F-3 tornado hit Barrie north of Toronto and resulted in eight fatalities. A line of thunderstorms swept through most of southern/central Ontario that afternoon and evening but the rainfall at Toronto was only 3.4 mm. Other strong tornadoes hit locations between Orangeville northwest of Toronto, to Peterborough northeast of Toronto. The author was living in Peterborough at that time and estimates about 30 mm of rain fell at his location, with large hail, the tornado track was further south (only an F-1 at that point). --- June notes --- (f) Until 2012 the June 2 (1947) rainfall record was the second consecutive one with 1.59" (40.4 mm) on June 1st (2d total 2.79" (70.9 mm). ^ June 12 2023 replaced record of 1.53" (38.9 mm) 1840 (g) While not setting a daily record, in 2000 this was the middle day of a three-day interval June 12-14 with 2.45" (62.2 mm) (h) June 22-23 1972 rainfall from remnants of H Agnes looping through NY-PA gave total of 1.36" (34.6 mm) (i) While Agnes and 1968 TS Candy (June 25-26 total of 0.99" or 25.2 mm) failed to set records, Audrey's remnants from the Gulf of Mexico set the monthly record. The track was from LA to w TN to central OH and dissipation of the tropical disturbance over Lake Ontario late 28th. With 0.29" on 27th and .01" on 29th, total rainfall for this event was 2.80" (early stages were probably frontal as Audrey ran up a weak frontal boundary already in place.) ... Also on 28th, 2.21" (56.1 mm) rain. ---------- =============================================== ---------- (note: any 2-day rainfalls mentioned in "notes" will start on the previous day and end on the day noted, unless otherwise specified ... also, refer to preamble to May-June section for information about other factors noted as causes of heavy rainfalls especially associated tropical systems. <<< July Daily Precip Records >>> - - - - - - -- - - - - - - <<< August Daily Precip Records >>> DATE _ Max rain (precip)_year___notes ________________ DATE _ Max rain and precip_year___notes July 01_1.30" (33.0 mm) 1842 ________________________ Aug 01_1.44" (36.6 mm) 1969 July 02_0.98" (24.9 mm) 1890 _ 2d 2.14" (54.4 mm)___ Aug 02_1.57" (39.8 mm) 2020 _ prev.1.35" (34.4 mm) 1991 July 03_0.97" (24.6 mm) 1928 ________________________ Aug 03_3.09" (78.5 mm) 1915 _ H1 1915 (e) July 04_1.98" (50.3 mm) 1878 _ fr wave _______________Aug 04_3.45" (87.6 mm) 1878 _ warm front (f) July 05_1.36" (34.5 mm) 1971 ________________________ Aug 05_1.49" (37.8 mm) 1870 _ 2d 2.81" (71.2 mm) in 1995 July 06_2.11" (53.6 mm) 1977 _2d 6-7 2.79" (70.9 mm) _ (a) _ Aug 06_1.67" (42.4 mm) 1968 _ 2d 6th-7th 2.62" (66.5 mm) 1968 July 07_1.52" (38.5 mm) 2013 _2d 7-8 5.33" (135.3 mm)_(a) _ Aug 07_2.29" (58.2 mm) 2018 _ 2d 7th-8th 3.15" (80.1 mm) 2018 July 08_3.81" (96.8 mm) 2013 _ 2nd highest daily amt (any mo)_ Aug 08_3.22" (81.8 mm) 1939 _ warm front July 09_2.42" (61.5 mm) 1960 _ weak frontal trough _____ Aug 09_2.44" (62.0 mm) 1891 _ frontal wave July 10_1.37" (34.7 mm) 2006 ________________________ Aug 10_1.63" (41.4 mm) 1955 July 11_1.73" (43.9 mm) 1937 _________________________Aug 11_2.34" (58.4 mm) 1841 _ 2d 3.59" (90.2 mm) July 12_1.89" (48.0 mm) 1840 ________________________ Aug 12_2.15" (54.6 mm) 1866 _ stalled warm front July 13_1.59" (40.4 mm) 1972 _ (b) ____________________ Aug 13_2.51" (63.8 mm) 1955 _ H Connie July 14_1.27" (32.2 mm) 1996 ________________________ Aug 14_0.99" (25.2 mm) 1995 July 15_1.60" (40.6 mm) 1869 _ warm front ___________ Aug 15_3.68" (93.5 mm) 1905 _ fr wave south (g) July 16_2.45" (62.2 mm) 1941 _ wave on wf ___________ Aug 16_1.31" (33.2 mm) 1919 _ (h) July 17_2.75" (69.9 mm) 1850 _ also 2.35" (59.7 mm) 1866 __Aug 17_1.48" (37.6 mm) 1950 July 18_2.03" (51.6 mm) 1942 _ 2d 3.70" (94.0 mm) ____ Aug 18_1.23" (31.2 mm) 1841 July 19_2.41" (61.1 mm) 2007 _ frontal wave __________ Aug 19_1.25" (31.8 mm) 2005 July 20_1.69" (42.9 mm) 1952 _________________________ Aug 20_1.68" (42.7 mm) 1904 July 21_2.70" (68.6 mm) 1919 _ frontal wave __________ Aug 21_1.95" (49.5 mm) 1918 _ warm front July 22_1.64" (41.7 mm) 1840 ________________________ Aug 22_2.74" (69.6 mm) 1968 _ 2d 2.43" (61.6 mm) 2010 July 23_1.59" (40.4 mm) 1927 _ (c) ____________________ Aug 23_2.25" (57.2 mm) 1975 _ 2d 2.89" (73.9 mm) 1968 July 24_2.00" (50.8 mm) 1841 _ (d) ____________________ Aug 24_1.76" (44.8 mm) 1982 July 25_1.71" (43.4 mm) 1950 _________________________ Aug 25_1.06" (26.9 mm) 1892 _ 2d 1.94" (49.3 mm) 1892 July 26_2.03" (51.6 mm) 1849 _ 2d 2.41" (61.2 mm) 2009 __ Aug 26_2.17" (55.2 mm) 1986 July 27_3.88" (98.6 mm) 1897_heaviest calendar day rain (any mo) __ Aug 27_3.25" (82.6 mm) 1843 _ ( i ) July 28_1.49" (37.8 mm) 1981 _________________________ Aug 28_1.48" (37.6 mm) 1950 ___ July 29_1.86" (47.2 mm) 1852 _________________________ Aug 29_1.41" (35.8 mm) 1893 _ 2d 2.70" (68.6 mm) 1893 July 30_1.34" (34.0 mm) 1905 _________________________ Aug 30_2.39" (60.7 mm) 1970 _ 2d 2.96" (75.2 mm) 1970 July 31_1.78" (45.2 mm) 1977 _________________________ Aug 31_2.19" (55.6 mm) 1901 _ frontal wave south ______________________________________________________________ Notes: (a) Both heavy rainfalls July 6-7 in 1977 and 2013 had similar origins, slow-moving cold fronts in very warm, humid air masses. (b) Three day rainfall total of 3.65" (92.7 mm) 11th-13th 1964. Author was measuring rain at home weather station 40 km west in Georgetown, somewhat heavier totals there (unfortunately records lost in much later move). EC had station in Georgetown also, located about 4 km southeast of the author's home, and their report shows 78.0 mm while at YYZ (airport) in between (18 km west of Toronto downtown) the total was 76.7 mm. Checking the regional grid almost every location (and there used to be quite a few, several dozen) had 70 to 80 mm of rain in this downpour which was thundery but more or less continuous for about three days. The main cause of this prolonged heavy rain was an unseasonably well-defined low pressure area from Colorado that stalled out over the region. At Toronto the amount recorded on 13th was the daily record until 1972. Even this many years later I can still recall the shock value of seeing a five inch rain gauge very close to overflowing. It is worth mentioning though, that despite being in existence for 180 years, Toronto's weather station has never recorded more than 4.0 inches or 100 mm of rain (which is 3.94") in one calendar day ... Hurricane Hazel (Oct 15-16 1954) is known to have produced 6-8 inch rainfalls northwest of the city, and further afield there have been rainfalls in excess of that, so it seems quite likely that one day Toronto (either city or airport) will record a much heavier rainfall. (YYZ had 126.0 mm or 4.96" on July 8, 2013, the date of the downtown location's second heaviest one-day total of 3.81"). The author has had that experience, located 150 km north of Toronto in summer of 1976 there was a stationary thunderstorm complex that dropped over seven inches of rain in six hours -- the author recalls dashing out to empty the nearly full gauge (same one) with a measurement made, then adding the amount left over at the end of the storm. There's probably no reason why such a storm might not one day set up right over downtown Toronto. In the May 12, 2000 event (which was covered by The Weather Network from their studios southwest of Toronto) some local reports suggested amounts near six inches on that date (the record listed above being 2.67") . ... The heaviest one-day rainfall above (July 27, 1897) was closer to 60 mm at several other locations then reporting, so that one seems to have maximized close to the weather station location. (c) Similar amounts to this daily record (July 23, 1927) fell on 15th and 17th, the one on 15th was almost another daily max, the 17th was well behind and ended up in fifth place for the date. This is interesting only because it shows that very similar weather events can fare rather differently on various dates depending on what has to be largely random distribution (being that close together in time at a static point in the seasonal temperature trends). On the other hand, singularities that concern clusters of similar events on nearly similar dates could hold a research significance. For example, the January thaw concept -- about a half century ago, people often talked about the January thaw and expected it to come near the 21st of the month. Some research I have done suggests that this phenomenon has been slowly progressing forward and that it was closer to Jan 18-20 in the 19th century, and may be later than the 21st-24th as identified in the 20th century. The thaw was not something that would come every year but you can see a shift in distribution of temperature, more active storms and rainfalls. As to a cause for that, no very promising concepts other than difficult to quantify paradigms about oscillations in the Pacific, or possibly since the drift is similar long-term to the precession cycle, something of an undiagnosed Sun-background stars resonance that induces a planetary wave. (d) There was very heavy rainfall in the later part of July and early August of 1841. From July 22nd to 31st, a total of 5.15" (130.8 mm) fell, boosting the month to first place for July total rain after a rather average first two weeks. (that total swells to 6.77" starting from the 13th). Then after a dry week to start August 1841, another deluge of 4.59" fell from August 8th to 11th (total within 30 days of 11.36" or 288.5 mm) and after a few more dry days, 1.23" on Aug 18th made it 12.59" ( mm) in just 37 days (Noah had forty). These very heavy rainfalls showed up in 1842 and 1843 as well in somewhat different format and so it may be part of the background situation that led to the historical phenomenon where some residents of the Great Lakes region (perhaps more so on the U.S. side of the lakes) were widely anticipating the end of days and making plans to reach higher ground (the Millerite prophecy for 1843 and 1844). This movement rejected its prophecy in Oct 1844 and converted it to a new paradigm which led to the establishment of the Seventh Day Adventist church. --- August notes --- (e) The two-day rainfall from remnants of H1 (1915) which moved up from the Gulf of Mexico were 4.35" (110.5 mm) Aug 3-4, 1915 ... also, with the new record set previous day in 2020, the 2d total 2nd-3rd was 2.46" (62.6 mm) with an additional (non-record) 22.8 mm on 3rd. (f) The heavy warm frontal rain (August's 2nd highest one-day value) on Aug 4, 1878 added only a slight amount on 5th to reach 3.54" but then another 1.26" fell on Aug 6th making a three-day total of 4.80" (121.9 mm) That was another daily record until 1968 broke it. The two-day amount associated for 1968 (Aug 6-7), a warm front, produced a second record also on 7th (0.95" or 24.1 mm) which fell in 2018. (g) Also in 1986, 3.08" (78.2 mm) fell on Aug 15th, which would have set a record on all but two days in August. This combined with an earlier amount of 0.17" (4.4 mm) for a total 2d rain of 3.25" (82.6 mm); the 1905 record value had no additional amounts on either side and was almost the entire monthly rainfall for August 1905. (h) On Aug 16, 1969 (about a day before H Camille was approaching landfall in MS) air mass thunderstorms west of Toronto dropped amounts of 144 mm (about 5.6") near Milton and Hornby west of the airport and south of Georgetown which also had over 110 mm. The Toronto downtown station had only 0.38" (9.6 mm). Toronto airport had about 30 mm. These appeared to be non-frontal air mass storms that formed near lake breeze boundary and drifted upslope from east to west (the author was on holiday and missed this event by two days). Road damage from flash flooding was evident in the heavy rainfall zone at that time. (i) Aug 27 1992, (1.55") 39.4 mm associated with remnants of H Andrew (after second landfall in LA) failed to set a record. Another .34" (8.8 mm) fell on 28th. (total 1.89", 48.2 mm). Also from Aug 26 to 27 2013, 2.37" (60.0 mm) fell, with 39.4 mm on 27th tied with the 1992 value for second place on the day (after 1843). The 3.25" (82.6 mm) combined with 9.77" (248.2 mm) in September (Toronto's wettest month ever) made for a total of 13.02" (330.8 mm) in only 35 days, even wetter than the July-Aug 1841 period of similar length.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 The format follows the posts above (see preamble two posts back for general details) September precip records are also rainfall records since there have only been two days with traces of snow (these are noted below). With a lot of interesting tropical connections and two-day totals, I will present September with a larger space for daily notes. Then it's on to October where we start to pick up measurable snowfall again, still quite a few tropical connections to rainfall amounts. ... Nov and Dec will be in a separate post after this one is finished. <<< September precip records >>> DATE __ Max rain (precip) _ date __ notes _ 01 __ 1.76" (44.7 mm) _ 1899 _ warm frontal wave _ also 1.42" (36.1 mm) 1878, 2d (31st Aug-1st Sep) 2.16" (54.9 mm). _ 02 __ 1.73" (43.9 mm) _ 1930 _ cold front _ also 1.93" (49.0 mm) 1854 1st-2nd _ 03 __ 1.42" (36.0 mm) _ 1981 _ 04 __ 1.37" (34.9 mm) _ 2012 _ 2d (1981) total 2.55" (64.6 mm) _ 4th 1981 (1.13" or 28.6 mm) had been record to 2012 _ 05 __ 1.49" (37.8 mm) _ 1910, 1918 _ 2d (4-5 1918) 1.89" (47.9 mm) _ 2d (5-6 1910) 2.20" (55.9 mm) _ 06 __ 1.99" (50.5 mm) _ 1853 _ frontal wave _ 07 __ 3.02" (76.6 mm) _ 1996 _ H Fran (from s.e.

Sept 13 1878 was a Friday. As noted in May (notes 21st) this was one of the heaviest three-day rainfalls on record. Also on 13th more recently, unable to match 1878, two other memorable rainstorms. The path of H Frederic (1979) brought the remnant low into NY state and Toronto had 0.94" (23.8 mm) on 13th and another 0.54" (13.8 mm) on 14th, total rainfall 1.48" (37.6 mm). In eastern Ontario amounts closer to six inches fell. This was basically the only rainfall in the month of Sept 1979 which was otherwise very sunny and near normal in temperatures. Then in 1996 an intense low formed over Lake Huron, some dubbed this the "Huronicane" because it brought strong wind gusts in places, but for Toronto, the main event was a rainfall of 1.24" (31.6 mm) with a three-day total rainfall (11th-13th) of 2.20" (56.0 mm). The low was linked by a trough to strong H Hortense off the Carolina coast moving northeast. (b) This record from 2021 replaces 1.87" (47.4 mm) from remnants of Hugo which made landfall in SC and tracked rapidly into the Toronto region maintaining TS intensity to about Peterborough ON where the author was then living, a very small eye feature was observed there at about 2345h local time and rainfalls there were over 50 mm. (c) Rainfall of 2.13" (54.1 mm) on Sept 29-30, 1896, was caused by the merger of Hurricane Four of 1896 with low pressure over the Great Lakes. The hurricane moved north from Georgia after a landfall near Cedar Key, FL. It is known as the Cedar Keys Hurricane and caused considerable damage in the southeast U.S. and mid-Atlantic states. Neither daily amount quite matched the records although the 30th was close at 1.21" (30.7 mm). ----------- ==================================================== ------------ <<< October precip records >>> Snowfall daily records return now, but two-day snowfall will not be relevant until November; any two-day totals in October that are not self-evident from the daily data will be explained in notes. Daily precip records are still entirely rainfall except possibly near the end of the month when a snowfall event in Oct 1844 that we only have as part of a monthly total may have edged out one of the last three snowfall and precip records (as explained in note for Oct 29). There continue to be associations of rainfall records with tropical events especially up to the middle of the month.

(alternative cases for 1844 snowfall discussed in note h below) _________________________________________________________________________________________ (a) There are no weather maps available for 1849, but from Caswell's Providence RI journal, can see that H3 came ashore on the night of Oct 6-7 and dropped 2.5" rain there (storm total). He reported strong winds and thunder but did not use the word hurricane. Elsewhere I was able to discover that H3 had skirted Long Island and hit somewhere near Cape Cod. The Ontario rain was either a later consequence of its inland track or more likely from a separate low already in place there. Temperatures at both Toronto and Providence remained near 50 F (10 C) for several days on either side of the rainfall event indicating a generally cyclonic upper steering pattern. Toronto had received light rainfalls adding up to 0.60" (15.2 mm) for the four previous days and added .03" on the 8th for a total event rainfall of 3.78" (96.0 mm). This was the heaviest October one-day rain until 1954 (15th) and remains the second highest one-day total for the month. (added later) _ The wetterzentrale archives now include maps for the 1840s and late 1830s. Some appear rather rudimentary (the Jan 6-7 1839 storm that hit Ireland looks much underdeveloped compared to other maps I have seen in research articles). So I am taking these only for their tracks and positions, the intensity portion may be very poor in places. The maps more or less match what I had speculated about the set-up for this 1849 event, a coastal hurricane graze capturing an inland cold-core low is suggested. Rather than looping inland it appears this hurricane stalled near Boston and then moved east after the phase. (b) Hurricane Hazel is probably the most notorious weather event of Toronto's considerable weather history. Although the storm was more likely a transitioning tropical storm as it crossed Lake Ontario after a landfall in North Carolina, it is usually referred to as "Hurricane Hazel" in recollections. The fast-moving storm created very strong wind gusts also (over 100 km/hr) and dropped heavier rain a little further west and northwest (8" or 200 mm at Snelgrove, ON northwest of the airport). This caused the Humber River, which enters Lake Ontario a few kms west of downtown, to flood and swept away a residential area causing around 80 fatalities. This event led to flood control "conservation" measures being adopted by Ontario's government. This calendar day rainfall is October's heaviest. In 1943, 1.35" had fallen on the same date followed by 0.67" on 16th (2.02" or 51.3 mm). Those two daily records survived 11 and 71 years respectvely. This rainfall came from a trapped frontal wave associated with strong H9 off the southeast U.S. coast. While that hurricane went on to a landfall in Nova Scotia on Oct 17th, the frontal wave was pulled into the hurricane's circulation after the 16th. (c) The rainfall record for Oct 19 was nearly matched in 1916 (1.70") and a two-day rainfall of 2.33" (59.2 mm) was associated with the approach of remnants of H 14 of the busy 1916 season from the southwest. Oct 20, 1916 was dubbed "black Friday" because of shipwrecks caused by the decaying tropical system on Lake Erie. (d) The heavy snow of Oct 21, 1969 fell mainly between afternoon and midnight; the author has a clear memory of it as he was a student at the university where the weather station is located and spent that evening watching a movie. After an earlier rain-snow mix, the snow accumulated rapidly to the depth stated but quickly melted the next day despite ongoing cold temperatures (it stayed below 4 C all day). This event is marked as heaviest one-day snow for October although it is probable that a heavier amount fell in late October of 1844, the problem being as explained in a later note, the specific date(s) of this 30.2 cm snowfall are not specified. I am hoping that the dusty old manuscripts (which I last saw in a basement storage area in the old weather bureau headquarters around the same time as this 1969 snowstorm) from the 1840s are still preserved somewhere (now most likely to be at the newer Downsview headquarters building library) and might hold clues to this and other questions about snowfall in years from 1840 to 1844. Also on this date (Oct 21) no space to mention as a note above that the 1965 maximum daily rainfall was a cold core low that dropped steady rain for about two days (21st-22nd) amounting to 1.99" (50.5 mm). Also on October 21, 1868, 2.0" (5.1 cm) of snow mixed with some rain fell -- this is one of the heavier daily snowfalls in October so rather unfortunate to lose its place when so many other days had much smaller values. This snow was produced by a cold east to northeast flow around low pressure in WV. (e) Worth noting that on October 26, 2010, a very deep 955 mb low formed over the upper plains and Midwest. The effects of this storm, dubbed the "Chiclone" were moderate for Toronto with 0.25" (6.3 mm) rain and a high of 19.7 C reported. (f) 2-day snowfall total of 3.0" (7.6 cm) in 1865 as non-record 1.0" added to previous day's 2.0" amount. (g) Also note that 1925 snowfall 2d total was 4.0" (10.2 cm) 27th-28th. ... The 2015 rainfall which was largely on the 28th edged out a 1973 record which was part of a long-term heavy rainfall event that was widespread in the region. In the 1973 event, The 28th rainfall (1973) was 1.74" (43.9 mm) followed by 1.34" (34.0 mm), 0.51" (13.0 mm) and 0.71" (18.0 mm) from 29th to 31st. This gave a four-day total of 4.30" (108.9 mm). The cause was a very slow moving low that tracked from about WV to CT in the four day period. Temperatures were constantly around 7 C during this long interval of rainfall. (h) We have the report of 30.2 cm snow in October 1844 and it seems most likely to have fallen around 29th-30th when temperatures were cold enough, and deep low pressure was reported to have moved through New England giving Caswell a soaking rain at about 45 deg F. The distribution of this snowfall for Toronto on a day to day basis is not known. The listed records for 29th to 31st then are all to some extent possibly not the actual highest values. Neither would the monthly maximum of 4.8" (12.1 cm) on 21st, 1969, be likely to have exceeded the unknown 1844 maximum value. The map archives on wetterzentrale were just extended back through the period (to 1836 now), and this confirmed my suspicion that a low pressure system tracking to south of Great Lakes on 29th-30th probably brought most of this monthly total (some smaller parts could have occurred earlier). The 31st looks dry on the map. So the 30.2 cm snowfall was probably something like 20 cm on 29th and 10 cm on 30th in 1844. This explains why the morning of the 31st set the all-time minimum temperature (-9 C) for October. Would suggest anyone using the data assume the daily snowfall records are close to the values just mentioned. Unless almost all this snow fell on the 30th, or unless there were rainfalls associated (we have no rainfall data at all for the month), no daily precip record was likely to have occurred. I have noted the possible alternative snowfall records in the table (green alternative lines). (g) - second 29th note - Rainfall from remnants of H Sandy moving inland over NJ and tracking towards Toronto, on 29th in 2012, remnants reaching the Toronto area by early 31st. As there had been low pressure in the area since the 27th, this turned into a five day rainfall event that was not as heavy as in parts of the eastern U.S., but eventually totalled 61.9 mm or 2.44" -- no daily record was threatened with any of these five amounts.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 <<< November precip records >>> Snowfall and two-day snow records return now, along with precipitation, although almost all the November records continue to be the rainfall records for the dates. This begins to change to more snowfalls and mixed events late in the month and into December. A reminder that 2-day snowfall totals end on the date shown, and begin on the previous date, even if no snow falls on one of the two dates. When two entries appear and both are larger than an associated daily record, it shows that a three-day snowfall sequence occurred. If two entries appear and one is the same as the snowfall, the second larger, it means that snow only fell on the following day in addition. Where three entries appear and the second and third are the same, it means that the main event was preceded by additional snow, but not followed by anything new.

(a) The 1929 rainfall was associated with a strong warm front and the 1911 snow which appears to have been a trough ahead of a massive arctic high over the upper plains states was not accompanied by rain. (b) The 1861 rain was associated with H8 of 1861 which made a landfall in the mid-Atlantic states and continued north across PA into NY state while gradually dissipating. There was also .42" rain on Nov 1st and .20" on 3rd for a three-day total of 3.75" (95.2 mm). There was another heavy rainfall on Nov 2nd in 1907 when 1.81" (46.0 mm) fell. This was from low pressure moving east through the region. The 1951 snowfall was a trough linked to a slowly developing nor'easter which deepened explosively on 3rd. See notes for 6th -- a second winter storm followed after a cold dry interval. (c) Just two days after a record high temperature was set for the month (1st, 1950) a two day snowfall began, accumulating to 5.0" (12.7 cm) by the 4th, mixed with 0.24" rain. The 1985 rainfalls on 3rd and 4th (no typo, they were identical) were caused by slow-moving low pressure to the southwest, somewhat similar to the late October 1973 event, and with another 0.51" (12.4 mm) rain on 2nd, the three-day total was 3.73" (94.7 mm) very similar to the aforementioned Nov 1-3 1861 total. (d) A second storm in early Nov 1951 tracked south of the Great Lakes and brought a heavy two-day mixed fall of 1.94" (49.2 mm) rain and 4.3" (10.9 cm) snow, or 2.37" precip (60.1 mm) over the 6th and 7th. Nov 6th becomes the second day in the data base to record both its record rain and snow on the same day (Jan 1, 1932 was the other). Also there was a record low min and max in the day before the storm began, the max on 5th (30 F) and min on 6th (15 F) are daily records. (e) 1977 rain caused by stalled low over Ohio valley. Very little additional rain on either date adjacent. The 1953 snow developed from low pressure moving northeast through PA and NY. Despite this record snow, the rest of the month turned very mild and set several records. (f) The 1913 record rainfall for Nov 9 was caused by a powerful storm that is more remembered for sinking numerous freighters on Lake Huron with its extreme northerly winds in that region west of Toronto. The deep low (sometimes called the "White Hurricane") originated in Georgia and moved north to western Lake Ontario. It sank a number of large freighters on Lake Huron with a death toll over 250, and brought destructive northwest winds to Cleveland OH together with heavy lake effect snowfall. The temperature in Toronto fell from 16 C before the storm's arrival to -1 C in its dying phases when some snow was added to the rainfall to boost the precipitation record. With rain that had already fallen on 8th, the total rainfall was 2.17" (55.0 mm). ... ... ... ... ... ... This is a time of year for celebrated storms, see note for Nov 11 ("Armistice Day" storm) and also on Nov 10, 1975, into Nov 11th, the "Edmund Fitzgerald" storm struck Lake Superior. The effects in southern Ontario were mainly strong southerly winds and warm temperatures with some rain, not of record value (a temperature record had been set on Nov 8, 1975). ... The 1921 snow event (6.4" or 16.2 cm) was caused by a low moving east across OH and PA. (g) The 1962 rainfall was produced by a low that moved out of the Gulf of Mexico into Georgia then north to become a closed low in PA. The 1898 snowfall event lasted parts of three days (9th-11th) and totalled 10.0" (25.4 cm). The low tracked from the south central U.S. to the lower Great Lakes and turned east. There was no associated rainfall. Other than the partly unknown Oct 1844 storm, this was the earliest ten inch snowfall event of any season. It came in an otherwise rather warm year especially for the era. (h) The 1940 "Armistice Day" storm on Nov 11 takes its name from the U.S. name given for their version of Remembrance Day. It was a dangerous blizzard in Minnesota and took the lives of a number of hunters unaware of the sudden weather changes about to hit them. The wikipedia article on this storm states that it began in the Pacific northwest and was there responsible for the end of the Tacoma Narrows bridge on Nov 7, 1940. The storm reached Iowa by the 10th and slowly deepened to 970 mbs, moved northeast across Lake Superior, and unleashed a raging blizzard on western Lake Superior and surrounding states. At Toronto, there was a two day rainfall of 1.94" (49.3 mm), a maximum temperature of 15 C on Nov 11th then cold southwest winds raced in with flurries and lake effect squalls in snow belt areas. Some minor snowfalls hit Toronto about three days later in the colder pattern that followed the storm. The article goes on to state that 146 people died as a result, about half of them stranded hunters who froze to death, and another significant number in capsized vessels on Lake Michigan. ... Until the 2019 snowfall record, 1933 (4.8") (12.2 cm) held it and this snow was followed by record cold temperatures on 15th and 16th. The 2019 storm was immediately followed by new record cold values (-12 C). (i) The 1881 rainfall event was fairly standard (low pressure moving towards Ontario from the plains states). From this point on, if later November and December rainfall events are of this sort, I won't note the details. ... The 1959 snowfall occurred in the opening stages of a three-day wet period that turned to rain on the 13th and 14th (a total of 0.69" or 17.0 cm). ... (j) From Nov 12th to 13th 1925, first day of nearly equal amounts failed to break the 1881 mark on 12th and produced a 2d total of 2.07" (52.6 mm). This was associated with low pressure tracking northeast to the south of Lake Ontario and temperatures were in the 7-9 C range for the entire duration. The 1997 snowfall on Nov 13th was produced by low pressure tracking from the Midwest to the northeastern states. It was a heavy wet snow (almost equalling the 1925 rainfall's precip value at 23.0 mm) but no rain was recorded. A further 4.4 cm on 14th and 1.6 cm on 15th gave a three day total snowfall of 9.8" or 24.8 cm. The snow remained on the ground until rain on the 20th melted it slowly. This length of snow cover in November is unusual for Toronto. This storm eclipsed the previous daily record of 3.7" (9.4 cm) from 1900. (k) The 1871 rainfall event was associated with a strong low that approached from the west and tracked into western New York. The rain started to mix with snow at the end of the day (14th) and turned to snow on 15th (a total of 2.2" (5.6 cm) snow was added). (L) The 2018 snowfall record for 15th (5.0") is estimated (as mentioned, from autumn 2017 onward, no daily snowfall data measured, only snow depth from station "Tor B" is available. The evidence includes 11.3 mm precip on a near-freezing day, similar outcome at North York with all snow given, 10.6 cm and 14.5 mm precip equivalent, similar partial snow depths by next morning (somewhat milder with rain, some melt likely). If this value of 5.0" is too high then 4.4" (11.2 cm) on Nov 15, 1881 was the previous record. (m) The heavy 1869 rainfall ended with a topping of 3.0" snow to augment its precipitation record status. The heavy 1932 snowfall was caused by an inverted trough tracking slowly east to the south of the Great Lakes. (n) The 1868 heavy rainfall came from a slow-moving low in WI slowly losing energy to a developing coastal. It was not quite cold enough for snow (temperatures were steady near 5 C). The 2002 2d snowfall noted had daily components of 12.6 cm and 9.8 cm, and beat out the 2d total for 1920 which added nothing from the previous day. Nor did the 1932 event continue after 15th-16th. The 1920 snowfall was caused by a strong coastal low. The 2002 event followed a similar track. (o) The 1851 rainfall (20th) came from a low somewhere around Ohio that slowly fed energy into a developing coastal low. Caswell's Providence journal remarks that skies clouded up progressively on this same date and then 2" of rain fell there on the 21st. Although the archived weather map has rather vague details south of the Great Lakes it is probable there was a considerably stronger low present than the map depicts for Nov 20 1851. ... The 1986 snowfall came from a coastal low forming from an inland low tracking east to south of L Erie. (p) The 1950 snowfall (Nov 24) was associated with an unusual strong northward moving low that energized a weaker low already in place and dropping light snow late 23rd, then brought even heavier snowfalls to parts of the inland northeast and Ohio valley states. Small amounts of rain were recorded to boost the precip slightly. It appears that the snow became light on the 25th and mixed with rain, then turned back to all snow on the 26th. Somewhat heavier amounts were reported inland west of Toronto through the 25th-26th. The annual Canadian football championship (Grey Cup) was played during the aftermath of this storm and is known as the "Mud Bowl." In 1962 the game was also played in Toronto and that time had to be suspended for a later finish because of dense fog -- the "Fog Bowl." A third event in late November 1965 was badly affected by very strong winds. It was around then that talk began about building a domed stadium (which is where the football team now plays). ... The 1877 rain was part of a three-day deluge with a similar map (slow moving low pressure areas to south) as the earlier Nov 2-4 1985 event displayed. The 1877 total was 2.15" (54.6 mm) from 24th to 26th. (q) Despite adding .08" to the precip from additional snow, the 1895 rainfall lost out to 1987 which had very similar numbers, 29.4 mm of rain and 3.0 cm of snow which had 4.0 mm liquid equivalent for a precipitation total of 1.31" (33.4 mm), compared to 1.26" (32.0 mm) in 1895. (r) The heavy rain in 1993 on Nov 27th eclipsed a record of 1.42" (36.1 mm) set in 1850. That event continued into 28th with a further 0.60" (15.2 mm) for a total of 2.02" (51.3 mm). ... The 1873 snowfall was caused by low pressure tracking from Lake Michigan to south of Lake Ontario. The week before this snowstorm added six inches (15 cm) and it was generally cold so there may have been as much as 25-30 cm snow on the ground after the 27th snowfall. Temperatures then dropped to record low values (minimum 1 F or -17 F on 28th). The snowfall event hides another similar fall in 1876 when 8.7" (22.1 cm) fell 26th-27th. Also 7.2" (18.3 cm) fell on these same two days in 1902. Also, in 1889, a two-day snowfall of 8.5" (21.5 cm) was recorded from 27th to 28th. This was accompanied by 0.85" (21.5 mm) rain on the 27th. The combination of that rain with 5.5" of the snowfall gave a daily precip of 1.40" (35.6 mm) which was not quite up to the level of the 1850 rainfall value. <<< December Precip Records >>> DATE__Max rain ___ date ___ Max snow ___ date ___ Max precip ___ date ____ Max 2d snow (year) __ notes _ 01 __ 1.05" (26.7 mm) 2006 _ 11.0" (27.9 cm) 1875 ___ 1.10" (27.9 mm) 1875 ___ 12.6" (32.0 cm) 1875 _ (a) _ 02 __ 1.28" (32.5 mm) 1848 __ 5.8" (14.7 cm) 1856 ___ 1.28" (32.5 mm) 1848 ___ 11.0" (27.9 cm) 1875 _ 03 __ 1.81" (46.0 mm) 1841 _ 11.0" (27.9 cm) 1890 ___ 1.81" (46.0 mm) 1841 ___ 11.0" (27.9 cm) 1890 _ (b) _ 04 __ 0.77" (19.5 mm) 1887 __ 6.0" (15.2 cm) 1898 ___ 0.77" (19.5 mm) 1887 ___ 11.1" (28.2 cm) 1890 _ 05 __ 1.95" (49.5 mm) 1870 _10.0" (25.4 cm) 1898 ___ 1.95" (49.5 mm) 1870 ___16.0" (40.6 cm) 1898 _ (c) _ 06 __ 1.25" (31.7 mm) 1962 __ 3.7" ( 9.5 cm) 1906 ___ 1.25" (31.7 mm) 1962 ___ 10.1" (25.7 cm) 1898 _ (d) _ 07 __ 0.79" (20.0 mm) 2004 __ 3.0" ( 7.6 cm) 1868 ___ 0.79" (20.0 mm) 2004 ____ 3.7" (9.5 cm) 1906 __ (e) _ 08 __ 1.12" (28.4 mm) 1866 __ 9.7" (24.6 cm) 1977 ___ 1.13" (28.7 mm) 1866 ____ 9.7" (24.6 cm) 1977 __ (f) _ 09 __ 1.75" (44.5 mm) 1841 __ 4.0" (10.2 cm) 1864 ___ 1.75" (44.5 mm) 1841 ___ 10.2" (25.9 cm) 1977 _ 10 __ 1.13" (28.7 mm) 1966 __ 8.7" (22.0 cm) 1992 ___ 1.21" (30.7 mm) 1966 ____ 8.8" (22.2 cm) 1992 _ 11 __ 1.20" (30.5 mm) 1899 _ 19.0" (48.3 cm) 1944___ 1.90" (48.3 mm) 1944 ___ 19.0" (48.3 cm) 1944 _ (g) _ 12 __ 1.39" (35.3 mm) 1972 __ 5.7" (14.5 cm) 1963 ___ 1.64" (41.7mm) 1972 ___ 22.5" (57.2 cm) 1944 _ (h) _ 13 __ 1.10" (27.9 mm) 1909 __ 7.0" (17.8 cm) 1873 ___ 1.10" (27.9 mm) 1909 ____ 8.3" (21.0 cm) 1873 _ 14 __ 1.07" (27.2 mm) 1897 _ 11.2" (28.5 cm) 2013 ___ 1.24" (31.5 mm) 1901 ___ 11.2" (28.5 cm) 2013 _ (i) _ 15 __ 1.41" (35.8 mm) 1869 __ 7.2" (18.3 cm) 1972 ___ 1.57" (39.8 mm) 2022 ___ 11.5" (29.3 cm) 2013 _(X) _ 16 __ 0.77" (19.6 mm) 1996 __ 9.8" (25.0 cm) 2007 ___ 1.00" (25.4 mm) 2007 ___ 13.3" (33.8 cm) 2007 _(j) _ 17 __ 0.90" (22.9 mm) 1921 __ 6.5" (16.5 cm) 1876 ___ 0.90" (22.9 mm) 1921 ____ 9.8" (25.0 cm) 2007 _ 18 __ 0.71" (18.0 mm) 1977 __ 7.1" (18.0 cm) 1979 ___0.71" (18.0 mm) 1977,79 _ 10.5" (26.7 cm) 1876 _ (k) _ 19 __ 1.27" (32.2 mm) 1860 __ 8.0" (20.3 cm) 1973 ___ 1.27" (32.2 mm) 1860 ___ 9.9" (25.0 cm) 1982 _ 20 __ 0.84" (21.3 mm) 1949 __ 5.7" (14.6 cm) 1951 ___ 0.84" (21.3 mm) 1949 ___ 12.9" (32.7 cm) 1973 _ 21 __ 1.11" (28.2 mm) 1905 _ 10.0" (25.4 cm) 1864 ___ 1.11" (28.2 mm) 1905 ___ 10.0" (25.4 cm) 1864 _ (L) _ 22 __ 0.79" (20.0 mm) 1990 __ 7.1" (18.0 cm) 2004 ___ 0.85" (21.5 mm) 1990 ___ 10.0" (25.4 cm) 1864 _ (m) _ 23 __ 0.87" (22.2 mm) 1996 __ 5.1" (12.9 cm) 1913 ___ 1.14" (29.0 mm) 1907 ___ 12.0" (30.5 cm) 1848 _ (m) (n) _ 24 __ 1.38" (35.0 mm) 1986 __ 7.0" (17.8 cm) 1884 ___ 1.38" (35.0 mm) 1986 ____ 7.0" (17.8 cm) 1884 _ (o) _ 25 __ 1.24" (31.5 mm) 1979 _ 15.0" (38.1 cm) 1872 ___ 1.50" (38.1 mm) 1872 ___ 15.0" (38.1 cm) 1872 _ (p) _ 26 __ 0.86" (21.9 mm) 1875 __ 9.0" (22.9 cm) 1933 ___ 0.96" (24.4 mm) 1875 ___ 23.0" (58.4 cm) 1872 _ (q) _ 27 __ 1.46" (37.1 mm) 1942 __ 6.4" (16.2 cm) 1938 ___ 1.46" (37.1 mm) 1942 ____ 9.0" (22.9 cm) 1933 _ (r) _ 28 __ 0.52" (13.2 mm) 1863 _ 11.3" (28.7 cm) 1968 ___ 1.13" (28.7 mm) 1968 ___ 13.9" (35.3 cm) 1968 _ (s) _ 29 __ 1.34" (34.0 mm) 1940 _ 15.0" (38.1 cm) 1855 ___ 1.50" (38.1 mm) 1855 ___ 15.0" (38.1 cm) 1855 _ (t) _ 30 __ 1.03" (26.2 mm) 1936 __ 6.5" (16.5 cm) 1853,1971_ 1.25" (31.8 mm) 1907 ___ 15.0" (38.1 cm) 1855 _ (u) _ 31 __ 0.99" (25.2 mm) 1906 __ 8.0" (20.3 cm) 1852 ___ 0.99" (25.2 mm) 1906 ___ 10.0" (25.4 cm) 1852 _ (v) ___________________________________________________ Notes: (a) The record snow on Dec 1, 1875 was preceded by record cold on Nov 30th (both the low minimum and low maximum for November occurred on the date). This snow appears to have been largely east-wind lake effect as there was not much organized synoptic scale low pressure in the vicinity (but with the severe cold continuing as high pressure retreated, the maps had a lake effect look to them). The snowfall was nearly beaten in 1979 when 10.6" (27.0 cm) fell. Its precip equivalent was only 16.0 mm. That one was produced by a fairly weak low to the south of the lower lakes and may have been substantially lake enhanced as otherwise the map would suggest 5-10 cm at most. ... ... ... ... The 2006 rainfall was the culmination of a two-day fall of 2.17" (55.1 mm). The Nov 30 portion of this did not quite beat the 1923 daily record. (b) Also on 3rd in 1990, snow changed to rain, 4.3" (11.0 cm) snow turned to an inch (25.4 mm) of rain, the equivalent precip was 1.52" (38.6 mm) indicating the snow was wet (ratio 8.2 : 1 as 4.3" gave 0.52" liquid, 8x.52 = 4.16). In forecasting, 5 to 8 to 1 ratios are considered standard for wet snow, 10:1 is "normal" moisture content snow, and 15:1 or higher is dry snow, 20 to 30 to 1 ratios can be encountered in very cold powder snow situations (usually compaction rates as well as runoff potential will be affected by these ratios). (c) The record rainfall (heaviest of December) on 5th (1870) came from slow-moving low pressure tracking east, temperatures were just high enough (4-6 C) to keep this from changing to snow as the low died out in New York state. The two day snowstorm in 1898 was a deepening low that tracked from the southwest into upstate NY. The previous heavy snowfall around 3rd of 1890 looked similar on the maps but less intense. (d) The record snowfall for the date is rather small compared to most days in December. It was challenged in 2019 with indications of about 3 inches or 7-8 cms (6.6 measured at North York, snow depth increase of 5 cm downtown from 6 mm precip). This may have set a record for the date if measured at more than the 3.7" (9.5 cm) of 1906. That fell mixed with 0.40" (10.2 mm) rain. (e) Before 2004, the maximum daily precip on 7th was from a mixed fall of 0.47" rain and 1.8" snow. (0.64" rain 1848). (f) The snowfall in 1977 (8th) was the second in three days -- a 20 cm fall on the 5th combined with this record daily amount on 8th to give a snow depth of 33 cm which increased again to 41 cm by the 12th. This all melted in a steady rainfall a few days later. About a week after that came mixed falls of sleet, ice pellets and freezing rain. There was a similar snowfall event 8th-9th Dec 1917 (10" or 25.4 cm). (g) The Dec 11-12 1944 "wartime blizzard" caused transportation paralysis as the war effort made it difficult to assemble enough manpower to clear the massive drifts. This low tracked from Missouri to Lake Ontario and produced the heaviest calendar-day snowfall in the records. A two-day fall in December 1872 was half an inch heavier. Meanwhile, the 1992 snowstorm (from a coastal low) continued from 10th into the 11th and dropped a total of 12.5" (31.8 cm). The author was living in Lakefield, 150 kms northeast of Toronto, at that time and recorded 60 cms or almost two feet of snow from this powerful 1992 storm. The snow only remained on the ground about five days before melting. (h) The heavy rainfall on 12th (1972) was accompanied by 2.5" (6.4 cm) of wet snow, with 10:1 ratio used, precip added as it would have before the protocol changed. The author has a recollection of this storm being a lot heavier for snowfall in suburban areas, with the heat island being enough to change the wintry precipitation to rain downtown. A heavy snowfall followed in a few days. (i) The maximum precip on 14th came from a combination of 1.06" (26.9 mm) rain and 1.8" (4.6 cm) snow in 1901. (X) _ The max precip on 15th came from a combination of 1.17" (29.7 mm) rain and 4.0" (10.2 cm) snow in 2022. Previous record the 1897 rain. (j) The 2007 snowfall (which began the previous day) was measured as 25.0 cm (Tor A) and that gave 25.4 mm precip. The observer for Tor B has a similar snow depth but only gives 18.6 mm which does not break the precip mark for the day set with a mixed event in 1927 (when 0.80" fell, mostly rain). As I cannot account for the discrepancy and North York has somewhat less snow but near 10:1 liquid equivalent, I will provide the Tor A precip as a daily maximum. (k) On Dec 18th, the daily maximum rain and snow tied for the record precipitation. (L) The Dec 21st record rainfall from 1905 was just missed by 1.09" (27.7 mm) in 1967 accompanied by record mild temperatures near 14 C. A more memorable rainfall was of the freezing variety in 2013. This storm lasted from 20th to 22nd and fell during temperatures near or below freezing, on top of about 10-15 cm snow pack from the earlier cited snowfall. There was considerable damage done to trees and as a result also to hydro-electric service. This storm was widespread in the lower Great Lakes region. The Tor B daily precip amounts (with Tor A in brackets) from 20th to 22nd were 8.3 mm, 17.1 mm and 14.4 mm (10.9, 20.1, 9.8) for a total of 38.8 mm (40.8 mm at A). Those convert to 0.32" (0.43"), 0.67" (0.79") and 0.57" (0.39") for totals of 1.56" (1.61"). About a third of that accreted to surfaces in the region. No daily records were set but the event was very disruptive with half a million Ontario residents losing power, many for days, in the pre-Christmas period. The 1864 snowfall was from a slow-moving low south of the lower lakes. (m) Dec 22 just edged out previous records for both rain and snow. The rainfall record had been 0.76" (19.3 mm) from 1889 tied in 1931. The snowfall record was 7.0" (17.8 cm) from 1848. A two-day rainfall unspecified by daily components of 1.75" (44.5 mm) fell on 22nd-23rd in 1841. From the maps now available, and comparing with Providence, it would appear that most of this fell on the 23rd where it would be a daily record value if greater than 0.87" (22.0 mm). So the daily rainfall (and precip) records for the 23rd are quite possibly around 1.40" (35.6 mm) from 1841 instead of what is shown in the table (n) Amounts of rain in both 1907 and 1996 equate to 0.87" but 1907 was 0.1 mm lower after conversion, gained its way back into the records by adding 2.7" snow for 1.14" (29.0 mm). (o) The rainfall record from 24th 1986 removed part one of a two-day rainstorm 24th-25th 1979. The amounts were 1.33" (33.8 mm) 24th and 1.24" (31.5 mm) 25th, for a two-day total of 2.57" (65.3 mm), the largest such total in the data series. The cause of the 1979 rainstorm was a slow-moving low from the central plains states moving gradually towards upstate New York. Temperatures were around 5 C for most of the rainfall. The 1986 storm followed a track somewhat further south and was done by the 25th. (p) The 1872 snowstorm on Christmas Day and what is now known as Boxing Day added up to 23" (58.4 cm) the largest two-day total in the data. It appeared to be lake enhanced as the low was a good distance south (in the Carolinas) and the main feature was severe cold (temps below 4 F or -16 C) and moderate east-southeast winds. This Christmas snowstorm must have been long recalled because it was 1901 before another snowfall even managed to reach 2.0" at Toronto. The heaviest snowfalls around 24th-25th include 9.0" (22.9 cm) in 1855, then 6.5" in 1852 and 5.6" in 1975. Other years with substantial snowfalls around Christmas eve into the 25th would include 1909, 1915, 1918, 1923, 1929, 1944, 1951, 1965, 2012, 2013 and 2017. (q) The 1933 snowfall of 9.3" on the 26th came in advance of a two-part cold wave that ended up with the monthly low minimum of -30 C or -22 F by morning of 29th. (r) The rainfall on 27th 1940 came from a nearly stationary frontal system and temperatures remained in the 2-4 C range. Despite that, the precipitation was mostly rain even well outside the city. The event ended with a small amount of snow as the low pressure eventually tracked through New York state into the Maritimes. (s) The 1968 snowfall on 28th was preceded by sleet and mixed forms (no rain was recorded just a very moisture laden 6.6 cm snow that yielded 15.0 mm precipitation on 27th). The cause of this storm was slow-moving low pressure moving east then north through the northeast U.S. to a position near central Lake Ontario. (t) The snowfall event on 29th 1855 was from a low moving east to the south of the Great Lakes. There may have been lake enhancement as it appeared to be about a 4-6 inch type snow producer. Another snowfall of ten inches (25.4 cm) occurred in 1876; this one appeared to be substantially lake effect streamers in cold east-southeast winds although there may have been a more general 2-4 inch type of snowfall from a weak low off to the south. The 1855 storm reached Providence and brought a similar amount of snow there overnight 29th-30th. (u) The 1853 snow came from a low that slowly merged with a powerful coastal storm. There was a three-day total of 12.2" (31.0 cm). The 1971 snow which tied that record was the second day of a total 9.1" (23.2 cm) fall. Of the coastal storm in 1853, Caswell wrote that it had been many years since a storm of such severe winds, snowfall and cold had visited the region, and he recorded a barometric pressure of about 28.70" (below 970 mbs), as well as a level of 16-18" snow "badly drifted" later by strong winds. The second low from the Great Lakes evidently moved through on the night of 30th-31st when he recorded 3-4 inches of additional snowfall. ... The maximum precipitation was neither a snowfall or rainfall record, it came from a combination of 0.93" rain and 3.2" snow in 1907. (v) There have been a number of similar snowfalls over the two days 30th-31st, including the noted 10" (25.4 cm) in 1852, also 9.9" (25.2 cm) the following year, and 7.6" (19.3 cm) in 1948. There have not been many substantial snowfalls around New Years eve in more recent decades. Then we get back to where we started this journey with the 7.0" (17.8 cm) snowfall on Dec 31, 1886 that added 2.1" (5.3 cm) on the first day of 1887. That was the two-day record for the first of January. Also note that 22.5 mm rain on Dec 31, 2022 combined with 9.6 mm on 30th, for a total of 32.1 mm which would have been a record daily amount on either date After interacting with readers and doing more research, these notes may be edited or updated, and new information may come to light. One overwhelming conclusion jumps out at me after looking at so many weather maps over such a long period of time. The northern hemisphere circulation used to feature storm tracks and jet stream positions that were several degrees south of where they are in modern times. It was much more frequent for low pressure to track south of the Great Lakes in the 19th century than in the 20th or 21st centuries. Whether it is a function of map-drawing bias partly based on insufficient data, or a physical reality, the maps often have more of an inverted trough appearance than is common nowadays.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Notable dry spells at Toronto ________________________________________ This will be a summary of dry spells noted in the research. I have collected both the absolute (no measurable precip) dry spells and relatively dry intervals when total precip was below a certain limit, broadly defined as less than .01" per two days for spells of lengths of at least ten days. This means a 10 day dry interval would have no more than .05" in total, a 16 day dry spell .08" etc, but I have included some marginal cases in hotter weather where a slightly higher amount would probably have had no impact on soil moisture. In some wetter months a few dry spells of eight or nine days are included. (.02" is 0.8 mm so in general terms these dry spells have little more than 3 mm precip even if they run to 15 or more days, by the time we reach a month's length, .15" or 4 mm is required, amounts like that are generally rated as driest month in the spring and summer and are never achieved in autumn and winter, but one dry spell in October 1963 ran almost the entire month. Some listings have a qualifying absolute dry interval and a somewhat more marginal extended interval, if combined with warmth, these marginal extensions would either deepen the drought (if occurring before) or extend it (if occurring after or on either side of the dry period). The graph format now introduced makes it easier to compare spells for duration and intensity. This summary lists the dry spells in chronological order within each month, and highlights the more significant of them with reference to longest absolute dry interval (traces are not counted). The spells that begin in one month and end in the next are listed for the month in which the majority of the drought occurred. If there is a dry spell with no precip and no small amounts are mentioned, the reader can assume there was enough precipitation at each end to disqualify any extension of that dry interval. Often the dry intervals take a form of absolute drought with small amounts at each end, but some have an inconvenient small amount, or two or three, in the middle of what would have been experienced as a very long dry interval. The more significant of the two measurements here is probably the length of the dry intervals rather than the absolute dry periods but I tabulate both in a summary. The amount of time that Toronto is in any given dry interval is roughly 1% of the total time elapsed, and ranges from 0.3% in November to January, to 1.5% in May to July. The table after the list will give the reader some overview of whether dry spells are steady state, increasing or decreasing in frequency. I offer my opinion with that table but the results are somewhat inconclusive generally speaking (more of a cyclical outcome than steady state, trends would be difficult to forecast for the next 30-50 years). No intervals with missing rain or snow data are considered (and none are suspected after reviewing maps or the partial information available). Years with missing snow data may be accepted from May to September only (applies to Sept 1840). It is not a factor in determining these dry spells whether precip was rain or snow. Some winter spells were also very cold, many warm season dry spells are also very warm, but not always, there is a type which runs near normal in temperatures and has high pressure dominating but from a western origin so the air mass would be classified cP. When that type warms up in summer it can feel like a warm spell although cool nights may keep temperature anomalies close to zero. However, many of these dry spells feature at least one record high temperature and some are associated with top ten months in the temperature rankings. It is not always the case but in the warm season, Toronto temperatures are inversely correlated with rainfall. In the cold season it tends to be the opposite, although the few dry spells uncovered in the colder months sometimes relate to near normal temperatures (again, due to a western high pressure origin). I have noticed that dry spells in spring are often precursors of later record warmth (for example, dry in second half March 1941 followed by a very warm April). This is a logical pattern if ridges in the upper atmosphere are progressive over two months. Since there are two methods to qualify (ten day absolute dry spell, extended with total below criteria) some extended dry spells have no significant absolute dry intervals longer than five days. See tables below. JANUARY Summary: There are few dry spells in January (35 in 32 different years, even relaxing the criteria by 10%). The frequency is similar to December but lower than all other months. In the table below "EDS" means extended dry spell and "ADS" means absolute dry spell. Amt means total precip amount. If all the mentioned precip falls on one or two consecutive dates, those are mentioned. A few extended dry spells have two significant absolute dry intervals. The length of extended and absolute spells is given whether all days are in the month or not. In one case, Jan-Feb 1877, the same spell is listed twice because it has two absolute dry spells in the two different months. Otherwise, spells that extend from one month to another are listed where the majority of days in the absolute dry spell reside and if not applicable, where the majority of the extended dry spell reside. Any number in brackets beside an interval length shows the number of days within the month and that is only shown when a top three count is involved (again, example Jan and Feb 1877). Notes can include some non-qualifying longer spells that surround the qualifying periods in the table. Longest spells that contain any days in some months may be noted in an adjacent month. Red highlights draw attention to these notes. Only the ADS lengths are compared in this table. The EDS lengths are compared for top ten in a separate table after December. This is because most of them run from one month to another with often nearly equal numbers of days in each, so ranking them by month seems pointless. January and December extended totals are relaxed to allow a reasonable number for testing trends over time.

Considering that no relaxed criteria are applied (absolute dry spells are allowed at 9 days but no higher amounts for extended spells), and the month is shorter, this is more significant an increase than the count itself would indicate. January and February share one extended interval but each have an 11-day ADS within that. One of the February dry spells has the more impressive ADS portion in January (the second of two spells in Jan 1919, but a longer portion of the EDS in Feb).

_____________________________________________________ (a) Also the longest qualifying EDS (marginal could go 50 days 0.26" to Sep 16th before rains began to return to more normal values. The period before this long dry spell was also rather dry, 0.37" July 14-31. Total 0.63" over 68 days. August 1876 is the only entirely dry month, and the 34 day ADS is 8 days longer than the second longest (Sep 2 to 27 of 1908). (b) This 1948 dry spell is listed for August although more of its EDS days are in September, because the longer ADS is entirely in August and for its association with one of August's hottest periods Aug 24-28 1948. (The September portion remained very warm and another record occurred on Sept 17th). (c) This dry spell was always just outside the criteria over various time scales but turned very hot for about a week towards the end of the interval, so it is allowed in like July 1919 as close enough given the degree of heat. The interval within the cited period within the criteria was Aug 10-24 (15 days) with only .06". So this is a genuine entry, but expanded in either direction into just slightly sub-criteria rainfalls. September's warmest temperature was near the end of this interval (2nd, 100F or 38 C). (d) This dry spell was extended despite a marginal outcome from a definite qualifier 17th-28th as .08" rain 16th separated two long dry intervals and the longer of two ADS intervals was in the earlier sub-qualifying stretch (.12" in 21d only .01" above criterion and it was quite warm throughout). SEPTEMBER The frequency of dry spells in September decreases slightly from the August peak with 75 in 71 different years. Length however seems to be similar, quite a few long ADS occur. One of October's ADS entries (1882-1) is equally shared with September (8 days in each month) and this is reflected in the 0.5 counts assigned to both months in the following tables. That EDS is assigned only to October as it added dry days after the ADS ended.

The month picked up 1.25" on the last day after a total of only .13" on 1st and 29th. (b) This 1984 EDS marginal but two qualifying spells on either side of 0.12" rain Sep 25. Merged into one. OCTOBER The frequency of dry spells in October is nearly identical to September with 75 in 69 different years.

That separated 21 and 14 day qualifying intervals. NOVEMBER For November, December and January, the criteria are relaxed to allow nine day dry spells. Tables will compare the numbers of ten day dry spells for a more consistent comparison. Lack of snowfall (and in one winter, rainfall) data eliminate five years from consideration although from the partial data most of the winters appear wet. The frequency of dry spells in November counting all cases noted here declines slightly to 65 in 62 different years -- the count of ten day spells (EDS) is 55 in 52 years.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Summary of Dry Spells 1840 to 2023 _______________________________________ In this table, only EDS or ADS of 10 or more days are counted. The longest EDS in any month must have at least one-third of its days in the named month to count. The first table below counts only dry spells of 10 or more days. From late October through the winter season to early March, the tables on previous page include some additional 9 day spells to provide a larger sample to assess changes over time in those months. These additional spells are tabulated only for ADS (zero precip) over nine days in the third table below. The number of ADS includes only those spells with the majority of days in that month, where equal, the EDS designation determines the ADS determination. Note that in a few cases, an EDS can have two ADS periods in two different months. The three measures of longest ADS are (a) _ any dry spell with any days in the month (b) _ any dry spell with at least one third of its days in the month (c) _ any dry spell (or portion) with all days in the month Sometimes as with January, these are all equal although may involve different cases (January sees a tie between a case that is (b) with another that is (c)).

Asterisks add one (or more) nine-day intervals in the three months that were scanned for them due to the low number of ADS of 10 days or more (Oct 21-31, Nov, Dec, Jan, Feb 1-10). The average number for 18 decades would be 23**... 1840-49 has a missing factor that makes 20 its expected outcome with 25 for all other decades (total 445 similar to actual count of 452, 440 within full decades to 2020) and there are 38 extra 9-day ADS intervals in the winter (so the expected harvest per decade is close to two).

Also not evident in these raw data, the emphasis has shifted from frequent spring dry spells in the coldest portion of the 19th century, to summer and autumn dry spells becoming considerably more dominant in the last third (since around the 1950s). At the same time, it should be noted that it would only take a slight shift in observing tendencies (for example, in one decade an observer who would note traces rather than .01" in marginal situations) and the frequencies could shift to a more (or less) equitable regime. The tendencies for the EDS count (in house on the excel file) shows roughly the same outcome and identifies at least one EDS in every year except 1843 which was the wettest year. The decade by decade count looks fairly similar (at a 1.8 : 1 ratio) to the ADS count. The tendency in the past thirty years has definitely been towards a highly variable autumn precipitation regime, some years dry and others very wet. The overall frequency of November dry spells has increased the most relative to expectations. This indicates a correlation with the upward temperature trend which is especially notable in mid to late November (an extension of the typical autumn weather pattern which quite often runs to spells of 8-10 days of dry or wet weather). Spring drought has decreased about as much as autumn drought has increased. The long-term trends for summer are quite flat and do not show much variation. This is the count of dry spells per decade (once again, * indicates 9-day ADS in winter "relaxed criteria" period). The anomalous dry spells are identified in red highlights.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Monthly temperatures adjusted for Urban Heat Island growth after 1881 As already discussed, Toronto has grown from being a small town with the weather station near the rural boundary, to a large metropolis with the rural boundary now located 30 kms northwest, north and northeast of the weather station, which is in a relatively small mid-city parkland setting close to the northern edge of the complex central business district. From the literature and comparison with available long-term data from rural Ontario locations, the magnitude of the urban heat island for this site is estimated at 1.1 C deg (or 2.0 F deg), and almost all of that was achieved as far back as 1980. Once a city grows past a population of about 3-4 million, additional heating conditions near the centre do not change very much if at all, the further increases take place at intermediate distances from the boundary, and it is also possible that recent moves of the instruments would have counteracted any further urban effects. The greatest rate of growth in the heat island was likely to have occurred from about 1910 to 1950 as Toronto grew from a mid-sized city (at an early stage of industrial and transportation based temperature stressors) to a fairly large city of over one million people with a lot of industry and automobile traffic. The decision is to start modifying the raw temperatures in the 1880s by 0.1 C and to further modify each decade by 0.1 additional to the year 1981 when the total of 1.1 would be achieved. From 1981 to 2020 all values have been reduced by 1.1. This amount is considered conservative and may not totally balance the early stages of the temperature record. There is also a related question of how effective lake breeze cooling might be today as compared to the early almost rural setting when the small town would have had no tall buildings acting as a partial deflection shield for the shallow and easily relocated lake breeze (which in modern times seems to favour inland excursions through less hostile territory west or east of the city). Although there is probably some seasonal variation in the magnitude of the heat island, until any supportable concept emerges for modifying these initial changes, we will go with this basic modification. I also considered making variable adjustments based on rainfall since a wet month is likely to be a cloudy month and therefore less affected. The problem with that would be uncertainty about what percentage of the time the rain took to fall, and the observation that wet months sometimes have one or two cold spells which would counteract the reduced UHI. In general terms, this set of changes should allow us to re-rank the months in a way that will better reflect the actual change in climate regionally, since apart from the urban heat island effect, other locations show very similar trends from year to year. So here's the same table of temperatures as earlier presented adjusted by the stated amounts. The annual values to second decimal also follow the same procedure ... rounding may not always follow.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Seasonal Temperatures adjusted for UHI The same corrections have been applied as used for the monthly temperatures. See the previous post for explanations (the range is 0.1 C reductions starting in decade 1881-90, to 1.1 C from 1981 to present). Adjustments are made to winters that straddle decade shift boundaries (e.g., the first change to 1880-81 was -0.07 rather than -0.1, etc).

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Taking the above data -- temperatures adjusted for UHI -- this chart is a schematic of the timing of the warmest ten seasons in each case. The number zero represents 10 and italic numerals represent ties. Three were tied for tenth warmest spring, two for fourth warmest spring as well as fifth, seventh and tenth warmest summers. Since there are no entries before 1878 (9th warmest spring), the next warmest ranked case for each season is shown for the interval ending 1881 (in blue typeface to make it entirely distinct, the value can be tied with others not shown later in the data, as for example winter 1841-42 which was tied with two others at 26th warmest). Also for winter, 1877-78 was 23rd, not displayed 1879-80 was 21st and 1881-1882 was 18th. Since the chart was first posted in 2020, tied 10th warmest summer (2021), 8th warmest autumn (2021) and 7th warmest winter (2022-23), tied warmest winter (2023-24), have also caused some revisions. Analysis follows the chart ... note 0 = 10th, italics for tied ranks ... and ^ is 11th (winter only, as 10th is tied in all other seasons) note: numbers that appear two-digit (post-1880) are years close together such as "12" for spring, which is for ed by 1st (2010) and 2nd (2012). Except for blue integers, no values in chart are greater than 11th. --- <<< Schematic of the Timing of Warmest Seasons (temperatures adjusted to UHI) >>> --- ______ 1840 1850 1860 1870 1880 1890 1900 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 2020 ______ winter __26___________23_____8__________________3_________^__________________6_1___4_59___71 winter spring __ 20_____________ 9___________________4________0_____0________ 6__ 04_7__3 8____12____ spring summer ___________45______________________9 7___________ 2__3_5___________________1__07_540_summer autumn _________(59)____29 _________9____________2______________3___ 5__________6__ 0_0_417 8 autumn ANALYSIS In the large picture, this distribution is very similar to most other global temperature data sets showing an accelerated tendency to warming since 1998 in particular. Some other intervals do fairly well. The second warmest autumn (1931) was followed by the second warmest winter (1931-32). Hot summers were frequent in the period 1949 to 1959 (and to a nearly similar extent from 1916 to 1921, 1916 misses out slightly by having a rather cold June). The 1970s were more notable for mild winters and warm springs than for anomalous warmth later in the year. The 1980s only managed to score during the springs, and summers other than 1983 and 1987-88 (not in the top ten but in the top 20) were notably cool. The earlier part of the record seldom produced seasons (even after UHI adjustments which gave them what amounted to a 1.1 deg boost relative to the last forty years) of anomalous warmth. But a closer inspection reveals that what tended to happen then was for anomalous warmth to last only through one or possibly two months, making it hard for any season to compete. For example, summer of 1868 had the second warmest adjusted July, a very hot month indeed, but the rest of the summer was rather average, giving the season a relatively modest 43rd place finish. Autumns were notably cold in the first third of the data, and it was not until 1881 that any year cracked the top forty (1865 also shown was the warmest before that, in t59th place). This may argue for the need for a larger UHI boost, but the value derived seems to be backed up by current urban-rural differences which cannot be larger than the assigned value since no rural control site would have a natural tendency to warmer average than central Toronto (meaning that the current urban-rural difference has to be the upper limit for any value chosen). What may be more of the actual cause is natural climate change from 19th to early 20th century when years at least became competitive if not overwhelming the more recent contenders. For example, with autumns, we find that 1900 began the era with top ten potential, and from then to the next entrant (1931) there were several respectable finishes. The tendency for years to produce one or two very warm months not backed up by a third month within a season can still be seen to some extent in the middle of the data set, so that the modern tendency to warm seasons is more of a consistency phenomenon than an absolute warming phenomenon. The two warmest Octobers (1947, 1963) both anchored seasons to finishing T-13th and 11th respectively. I think the most obvious feature of this chart may be the frequency of recent warm seasons but a second prominent aspect is the change from the scarcity before 1900 to the relative abundance that followed. So as I've been saying the modern warming phenomenon seems to be embedded in a longer interval of naturally sourced warming that may be increasingly modified by human activity but is not totally caused by it altogether. Something worth noting is that some very hot summer intervals seem to fall into seasons that finish around 30th to 60th overall, showing that their appearance may be related to a higher variability aspect of the circulation. Summer 1936 (105 F) was ranked T-51st, summer 1911 (103 F) was tied 45th warmest, and summers of 1916, 1948 and 1953 were no warmer than 28th. Those summers produced the highest extreme daily temperatures along with 2011 (101 F) which made the top ten. On the other hand, some top ten summers only barely made it to the average of 35 C for an extreme maximum.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 This is the final post that will be reserved to remain in place with the data sets. It will note ongoing monthly and record daily events moving forward into year 181 of the study. So far, March 2020 has been a relatively mild month with one near-miss on daily records (17.2 C on 9th of March happened to fall against a particularly warm day in March 2000, would have set a record for March 10th or 11th, but not for the 9th). (added Apr 7th _ The month ended up being the adjusted 12th warmest March in the series). Despite that, no new daily records were set, and in fact only three days exceeded 15 C which is fairly low compared to some years. It was the near total absence of late winter cold that led to the month climbing as high as it did. For precip, it was a relatively normal March, 63.9 mm of which I have assigned only 5 cm (equiv to 5 mm precip) as snowfall. While the Toronto City location continues to report, the North York station unfortunately stopped reporting around the time of the lockdown which may mean it is not being monitored. The airport weather station continues to report, and had only about 7 cm of snow. The 5 cm is supported by total increases of snow depth on three occasions of 5 cm, one or two cm at a time. The weakest daily rainfall record (23rd) came within 0.4 mm of being broken but remains 12.5 mm 1926. The tables in the study will be edited to reflect new data but I won't reorganize the ranking tables every month, just indicate the ranks of the new months, until we have a group of twelve new values (after Feb 2021) then all twelve can be inserted into the ranking tables to keep them evenly spaced. Same goes for precipitation. I am just hoping that with the current health crisis the Toronto data will continue to appear, but so far so good. We haven't had any missing days this past winter at all, the worst of the missing day phenomenon took place back around 2012-13. April 2020 turned out rather cool at 6.6 C and after UHI correction (5.5 C) is below the long-term average, only a small amount of snow and near-normal rainfall. May 2020 has started out quite cold and is threatening daily cold records as posted separately below. July 2020 narrowly missed becoming warmest month on record (this is still July 1921). In raw terms summer 2020 ranks 2nd, in adjusted to u.h.i., 4th. Despite these very warm rankings, the highest temperature of summer 2020 was 35.5 (96F) which is barely above the long-term average. And despite having a lot of very warm minimum readings, only one (24 Aug) tied the existing record of 71F. Link to comment Share on other sites More sharing options...
Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Depending on the report posted for today (9th May) there may have been a very unusual all-time daily record minimum established. The record was and is 29F from 1850. Since that was set, the coldest reading on the 9th of May was 32F in 1947. 29 F was the minimum (-1.5 C) for the 8th which came within 2 F deg of the 1842 daily record for that date. Hourly observations at the airport (20 km west of the downtown location) were as low as 26 F with a brisk northwest wind. The air mass is so cold that lake effect snow streamers are showing up on radar, and 6 inches of snow fell in central Vermont overnight as the cold air created a coastal low. A clipper type system may bring a rain-snow mix to the lower Great Lakes tomorrow. Daily snowfall records by this point in May are becoming a mixture of small measured amounts and traces. The cold spell mentioned below in 1923 did come with a snowfall of 1.3" on May 9th (the day before the 27F record min) and 1966 had 0.5" on the 12th. Will be reaching out to (N American) forum members and friends in Toronto to get any reliable downtown snow estimates from the passing snow showers, one report between the airport and downtown already mentioned snow accumulating in heavy showers. Daily low max for the 8th was 41F (1947) and this was missed by just one degree (5.7 C = 42.3 F). Daily low max for the 9th is 43F (1966). This may be challenged today as well. I report all these in F deg because prior to 1976 the daily temperatures were recorded to nearest whole degrees F. Nowadays we see them reported to nearest 0.1 C. Some cases occur where the new reading sets a record against the converted value but as that's from a range, we cannot be sure the record is valid so I count them as ties when the Celsius conversion to F (whole deg) is equal. It has been 97 years since a daily record minimum was established in May (10th 1923 was 27 F). And the 29F is the lowest temperature at the location since May 1926 equalled it. There have been several 30F readings in the intervening century. In the first few decades when there was no large city, minimum readings of 25 F were taken on two different occasions (3rd, 1867 and 6th, 1854). The lowest max in the month was 38 F set on three occasions. The latest into the month was the 11th (1857) so today's reading would have to be under 38 F to be a "benchmark" type of record (latest in season). The most recent low maximum in May was in 1979 although on that same date in 1999 (25th), a reading was taken that was lower than the mark broken by 1979 -- 1979 was 50 F, 1999 was 51 and the previous record was 52 in 1925. This table shows when the most recent all-time daily minimum records were set at Toronto (the change is more due to the urban heat island growth than climate change as shown by the more recently set daily low maximum records ... winter does better because stronger winds are often associated with record lows then, which makes the urban heat island less of an obstacle: JAN __ 1994 FEB __ 1980 (leap year day, 1943 for non-leap years) MAR __ 2007 APR __ 1997 MAY __ 2020 ? (1923) JUN __ 1924 (1992 came within 1 deg) JUL __ 1925 AUG __ 1982 SEP __ 1959 OCT __ 1935 NOV __ 2019 DEC __ 1962 This is partly a matter of timing, a reading of -11 F on 25 December 1980 would have set a daily record on 24th or 26th but missed out on the 25th. _________________ (added on May 10th) It is confirmed that a daily record minimum was set on 9th of May, with -2.1 C converting to 28.2 F or 28 to replace the 29 from 1850. So that is the first May record low minimum at the location since May 10, 1923. The daily maximum of 6.5 narrowly missed tying the record low maximum of 43 from 1966, as 6.5 converts to 43.7 and rounds to 44 F. The station only reports precip and does not separate rain and snow, there was no report of lying snow but that would have been at an early hour before the snow possibly fell. The precip was 1.0 mm. At the airport weather station, where the minimum was -4.7 C, 0.4 cm of snow was reported for the day and that appeared to be all of the precip that fell (so not a mixture there). Have not heard back from my Toronto contacts yet about snow that might have stuck in areas close to the weather station. For the records will probably assign the 1.0 mm precip as 1.0 cm snowfall, not a daily record as there was 1.3" (3.8 cm) in 1923. (added on May 16th) The unusual cold spell continued for several more days and Toronto (downtown) had its latest frosts since 1936 (min 32 F on May 16) with readings of -0.4 and 0.0 on the 12th and 13th. Before the -0.4 C reading on 12th, the latest 31 F or lower reading in the observational record was 30 F on May 21, 1924. On that occasion the next day recorded 32 F. Going back further into periods with ever decreasing UHI barriers to late frost, May 22, 1895 had a 29 F reading which was also the next extension (going back in time) of the frost season then we find 31 F on May 29, 1889 (where I consider the UHI to be just starting up at 0.1 C, possibly 0.5-1.0 for calm, clear nights). Before that the frost season gradually works its way into early June by 1859 (5th was 32 F) although the first instance of a 31 F or lower reading later than 1889 was May 30, 1856 (31F) and the absolute latest values for both sets occurred with the 28F reading on June 10, 1842. June frosts occurred in only 1842,1843 and 1859. After those events, 35F in 1864, 36F in 1869, and 37F in 1945 represent coldest minima in the series. Since 1945 the coldest June minimum was 39 in 1949 and since that, 41 F in 1980. This May 2020 cold spell has now produced six consecutive days with lowest values since the book era (1967) in my research file, where I have noted extremes from the publication (to 1967) and since then (from internet source). With one exception, these have replaced values in both low max and low min categories from the 8th to the 13th. The deepest cold has now departed with near normal temperatures and rainfall more recently. The coldest May in recent decades was 1967 (mean 10.2) with 1907 at 9.0 and all-time 1867 at 8.5. The mean so far this month has been only 7.8 (through 15th which boosted it from 7.4 on 14th). The value for May 1-15 of 1967 was 8.2, the second half of that month remained quite chilly. Model forecasts at present make it appear that May 2020 may finish around 10.5 to 11.0 C. The coldest May since 1967 is 10.9 from 1997. (all the above not adjusted for UHI, 10.9 was reduced to 9.8 for long-term comparison and ranked t-14th coldest, 1967 reduced to 9.3 which ranked 8th coldest). (added on June 2) _ May 2020 warmed up considerably after 20th and even added a new daily maximum record on 26th. This left the monthly average closer to normal although still below especially after UHI adjustment. The new May and spring 2020 averages are edited into the tables above.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 Ranking seasonal precipitation Ranking seasonal precipitation These ranks include some estimates for years between 1840 and 1848, although most of the data exist for those years, some have missing rainfall or snowfall monthly totals. The estimates are based on an examination of weather maps now available, comparison to events at Providence RI, and temperature trends as indicators of precip activity. In most cases the estimated values fall close to long-term normals and so appear in roughly the middle of these tables where a missing tag would appear anyway. Like the EWP tables, dry extremes are at top and wet extremes at bottom. Ranks run from 1st to 91st dry, the median is 92nd driest/wettest and then ranks run from 91st to 1st wettest, in order from top to bottom of the tables. Ties are listed in chronological order and must be inferred by the reader in whichever order required. All four seasons now have 183 ranked values (as of end winter 2022-23). Amounts are in mm and include liquid equivalents of snowfalls (except that all measurable summer precip is rainfall). Winters are Dec, Jan and Feb, springs are Mar, Apr, May, summers are Jun, Jul, Aug, and autumns are Sep, Oct, Nov. ________________________________ DRY Rank __ Winter __ (amt) ____ Spring _ (amt) ___

01 WET ____________________________________ All four seasons are arranged by wettest and driest 91 seasons, and rank 92 is the median value (for 183 years, 92 is both 92nd driest and 92nd wettest). The table began with spring 1840 so that tables expand by one row after each winter season is completed. The next expansion of the table will occur after winter 2023-24; the four seasons in cycle 184 will be listed below until incorporated. The table was re-edited in March 2024, to include the four seasons from spring 2023 to winter 2023-24. Spring 2023 entered table at 254.0 mm, 35th wettest. Summer 2023 entered at 247.3 mm, 58th wettest. Autumn 2023 entered at 105.8 mm, 3rd driest. Winter 2023-2024 entered at 199.2 mm, 79th wettest.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 NYC data section now begins ... Comparisons with NYC (Central Park) 1869-2023 I have obtained the monthly and daily data for NYC (Central Park) which runs from 1869 to Apr 2023. Since very few warm weather records at Toronto have survived from 1840-1868, there is almost total overlap of record highs and high-ranked months. The overlap of cold records and cold months is more impacted by the frequency of appearances of 1840-68 in the Toronto data. As expected there is a good correlation between the two series although specific months show some differences. Many of the record highs at NYC occur either on same day as Toronto or 1-2 days later in warm spells of several days' duration. When not the same years, the NYC records often rank 2-5 in the Toronto daily series for same dates. There are a few occasions when NYC set a record high with no above normal reading associated at Toronto; these cases usually involve a low tracking between the two locations placing NYC in the warm sector. When I come to listing some NYC daily records I will highlight these, but the frequency is only one or two cases each month. The NYC data are collected in F deg. I have converted them to C but using two decimals to preserve the ranking (using one decimal would add numerous ties of months that were separated by 0.1 F deg). The first table offered will be raw mean monthly and annual temps. The second table will adjust those for the New York City urban heat island. Although I believe this heat island is about 1 F deg larger than Toronto, it had probably begun to impact temperatures before 1869, so I have applied the same changes to New York City as to Toronto over the period of record with the proviso that the adjusted values are still perhaps 0.5 C higher than the location would read with no urban effect. But the year to year comparison is set as similar to Toronto (implying a similar increase in urban effect). As a rough test of this assumption, the 1871-80 mean temperature for each station was compared to its 1981-2020 average, and similar increases have been noted. This will be further illustrated with tables of mean decadal temperatures at each location to follow this initial listing of the NYC raw data.

Roger Smith Posted September 5, 2021 Author Share Posted September 5, 2021 The raw data for NYC can now be compared to raw data Toronto (downtown) over the overlapping period 1869-2023. The more extreme values are probably of most interest, so I will start these tables off with top and bottom 20 ranks for NYC and show in brackets the equivalent rank for Toronto. The ranks for 1840-68 assigned for Toronto will be filtered out so (especially relevant to the colder end of the rankings) the ranks shown for Toronto will have the same range as NYC (1-154 for months already recorded in 2022, 1-153 for months not yet recorded ... this table will be edited and maintained going forward). Ties will show up in this format since I plan to show each month in a separate table, the rank numbers will run from warmest as rank = 1 to coldest = rank 153 or 154 but ties for NYC will show up in the ranking column and also in the Toronto equivalent values in brackets. The Toronto actual (also in C) will be shown so that any pattern of differentials can be assessed later. Will start this off with January to March and post three tables in each post going forward. The middle ranks will be added but will post the extreme ends when complete as they will be most interesting to survey. Years clustered around the middle ranks have very small differentials and larger quasi-random differences in ranks are likely to become a feature there. It should be noted that these tables are presented in the opposite order to the Toronto tables which ran from coldest at the top to warmest at the bottom. Partial reason for that is the emphasis on recent warming, which makes warm rankings perhaps more urgent, also with the ability to show tied ranks, I prefer to show them in descending order which is the way most people think about ranks (instead of having two very warm months tied 145th coldest). And there is the factor of more missing Toronto ranks near the bottom of this format, having them near the top would be immediately confusing for the reader. You'll note also this is comparison of raw data (pre - UHI correction) and part of the thinking here is that the NYC urban factor may be reset once this work is finished. Ranks will reverse at the mid-point so that the colder values can be compared in terms of coldest rather than high values of warmest (e.g. coldest will rank 01 not 153,54). In all cases, tied ranks will be shown in chronological order with earlier values higher in the table. Toronto ranks from the opposite side of the median of overlapping ranks will be colour coded, the blue ranks above the median are drawn from colder than average for Toronto and the red ranks below the median are drawn from above average ranks. A brief analysis follows the tables when completed. Thanks to Don Sutherland of the American Weather Forum for assistance with the data procurement and some local knowledge about site conditions and locations for NYC. The station was moved from the margins of the park to a more central location around 1920. I will be trying to assess whether that move left any imprint on the differentials. Just being in the large urban park probably takes a bit of the edge off the urban effect which might be considerably larger for a station that had a similar aspect to Toronto downtown (in a much smaller parkland setting).

ranks is about 10. The spread is not much different in sectors of the data. This shows a fairly high correlation between the two locations. The coldest NYC rank to match with a warm-half Toronto rank is 46th coldest 1988. The warmest NYC rank to correlate with a cold-half Toronto rank is t42nd warmest 1907. Between these about half the cases are cross-median but these are the largest differentials at about 40 ranks (out of 152). For February the correlation was even closer and the average rank differential dropped slightly to 9. In March the differential in ranks increased slightly to an average of 11, but there was good correlation generally at both ends. Link to comment Share on other sites More sharing options...

result the coldest three Mays and coldest five Junes at Toronto pre 1869 are not included in comparison) There is more spread in ranks in this spring to early summer portion of the year, and it probably has a relation to storm tracks in these months. Correspondingly, some warmer spring months at Toronto appear to have medium-warm ranks for NYC. When the ranks are from different halves of the data such as June 1883, quite a warm month for NYC but average for its era at Toronto and therefore well into the colder half of Toronto raw values, the Toronto rank is colour coded to show that it refers to the opposite half, otherwise in each half of the table above and below this commentary area, ranks are for that half (warm above, cold below). As 152 years are being compared, ranks run to 76th warmest or coldest. April does have overlapping ranks at the median for Toronto. With 2023 now added, the group at 6.9 (four years) are t77th warmest and also tied 76th coldest. The rankings given in the table belong to the same half of data as NYC temp justifies. NYC median is now 78th warmest and coldest (of 155) 10.61 in 1931. May for Toronto now has a median of 13.0 (five tied 74th warmest to include 78th warmest and tied 78th coldest). The median for NYC is now 16.56 78th warmest and coldest (1994). Note May 28, 2023, based on estimated final values near 17.22 NYC and 13.6 Toronto. To be edited as necessary. June (to 2023) if warmer than values mentioned will have a large group that straddles the median, for Toronto 18.7 is both tied 75rd warmest and 73rd coldest with a total of nine years included. NYC ranks t74th warmest and t77th coldest are equal and this total of six years also straddles the median which is now 78th warmest and coldest. June is one of the rare months that will finish considerably different in ranks, currently estimated to finish 43rd coldest for NYC and t49th warmest for Toronto.
