NYC daily temperature and precip records U.S. weather records have one different aspect to Canadian, the winter precip is not recorded as daily rain, snow and precip with sleet a separate variable, but instead, you get daily precip and daily snow which can include sleet (but only in terms of its depth, not water content). Therefore looking at older data, there is no straightforward way of determining how much rain fell with snow in mixed situations since the liquid equivalent of snowfall was always being determined, not only from 1962 on as with Toronto, but as early as the first day of records (Jan 1 1869 had 9.0" of snow and reported 0.75" precip. That must have meant that the 9.0" snow was either melted to 0.75" or some combination of that snow and undisclosed rainfall added up to 0.75" ... and so on throughout the records. Temperatures and historical records can give a fairly good idea of which snowfalls were not mixed with rain, and obviously any day with more precip than a 10:1 meltdown of the reported snow is a candidate but it could still be all snow with the right ratios. Therefore, the following records will miss one category available for Toronto, max rainfall (in the snowfall season), it can be safely inferred that max precip from mid-April to about mid-November is almost always or always max rainfall (certainly always in the snow-free season which is late April to late October). These records are all listed in their measured values, deg F and inches of precip or snow. As with the Toronto records, maximum 2d snowfall refers to the two days ending with the date in question. A 2d snowfall with an asterisk (*) here is in fact only a one-day snowfall with nothing added from the previous day, or in other cases it is a one day event from the previous day (**) with nothing measurable on the day of listing. Any two day snowfall which does not produce a daily record has the two values listed; any that is not the sum of two daily records can be worked out by taking the daily record and the remaining quantity. A few near miss values that would be records on many nearby dates (but not their own date) are listed after each month. Anyone interested in evaluating how similar the record values might be from Toronto vs NYC could open a second window with those and check, my subjective evaluation is that about half or slightly more of the daily temperature records are from the same years, with another significant grouping being top five outcomes at each, and a few are cases with significant warmth or cold only hitting at one location. There are fewer overlapping precip daily records and few snowfall cases because NYC tends to do well with coastal "nor'easter" type snowfalls and these often exclude Toronto or else Toronto is sometimes in a much lower snowfall zone near the outer edge of the shield. This is similar to how some summer rainfall records at NYC are set. You can find some overlapping cases though, a strong low moving east at about 40 to 43 deg N could give both locations heavy precipitation. Some winter precip records at NYC are mostly rain there and correspond to record snowfalls at Toronto. Note -- monthly extreme values in each category are highlighted in bold. A bold underlined value is also an annual extreme. Period of record 1869-2022 (into Feb 2023). During the snowfall season, the max precip has a letter code beside it. R (as with Jan 1, 1888) means all rain, no snow. RS means a mixture, S means all snow (from all known indicators). A number in brackets to the right of low min is the daily max that has failed to produce a low max record but is close (see Jan 5, 1904).

(this was posted Dec 9, 2020) ... As you'll see from the new thread title, NYC data (1869 to present) have been added to the Toronto data and compared extensively for temperatures. Work in progress here on the precip for NYC, will be posting some tables for those over the next few months. November 2020 was warmest on record for NYC in both raw data and adjusted for urban heat island data. Toronto came in with a tie for fifth (with 2009, 2011) meanwhile 1975, 2001, 2016 and 1931 remain first through tied third in raw data, the order is similar for the urban heat island adjusted except that 1948 moves marginally ahead of 2020 which drops into a tie for sixth (again with 2009 and 2011). In general terms, the top ten for raw data at Toronto have been infiltrated by an average of five recent years, with December being entirely taken over by new entries since 1982 hit the top spot (later beaten three times). October fared rather well holding on to a top three of 1947, 1963 and 1971 through a number of close challenges. This past summer, July 2020 moved into second place behind July 1921 but quite a few of the top ranking summer months are from well back in the data. This is even more true of the adjusted set filtering out the urban heat island and hopefully leaving a more representative record of the changing climate. January 1932 held on to top spot also, but many of the old top ten for January are now in the 11-20 range. February has been even more transformed. The celebrated consecutive warm Marches of 1945 and 1946 slid into 2nd and 3rd after 2012. April and May have seen a few new top ten entrants but retain quite a few of the ones that were set "back in the day" (and I am getting old because I remember some of them, May 1962, 1964 and 1965 were quite warm and I had just begun my personal weather station in my high school years). The overlap of Toronto and NYC data is not quite 1 to 1 in terms of rankings of months but there are not many cases of large ranking differentials. There is one type of circulation pattern that can produce a warm month in Toronto and a relatively cool one in NYC, that being a ridge over the western Great Lakes coupled with a mean trough at about 65-70 W allowing frequent offshore lows to form, and keep the east coast in cool northeasterly flow. This happened in both July 1916 and 1921 which were very hot in Toronto and considerably cooler in New York City. It has been a rare occurrence overall. On the other hand, a tight jet stream thermal gradient can produce the opposite result, a warmer than average month in NYC and a cool one to the north of an active storm track for Toronto. That happened several times in 1979-80 and also back in the 1880s, but once again, it is not very common. I had colour coded the ranks in the comparative tables where Toronto crossed the median, and I can still see the red and blue colour coding on my screen, if you cannot, let me know, I can probably edit through those tables with a different format to show the rank differentials (because I number them from both top and bottom, example of a colour code situation can be seen in the July entry for 1916 (raw data table) which sits at the t54 coldest position for NYC and is shown as t07 for Toronto but that's tied 7th warmest and is colour coded red. That sort of spread is unusual, the average separation in ranks is around 12 (out of 152). In this study I reassigned ranks to the 152 of 180 Toronto years so they are continuous from 1 to 152, not intermittent from 1 to 180, then they were renumbered from warmest or coldest to ties reaching 76th. This will be rebooted each year (the ranking year is going to be January to December for this study since NYC started with January, so the March 1840 startup for Toronto is irrelevant to the ranking system here). I have not yet posted NYC daily records although there is a log of annual maxima and minima in two comparative tables for annual mean temperatures. From those you can see a lot of overlap in extreme temperatures. Both locations had their hottest day on July 9, 1936 although for Toronto that was tied on the 8th and 10th, and the values were almost the same (106 NYC, 105 Toronto). The hottest August days in 1918 and 1948 were also similar, as were the May 1962 (and 1969), June 1964 and September 1953 extremes. The February 1934 cold spell was equally prominent at both locations (Toronto had colder readings before the 1869 overlap). The magnitude of the urban heat island at Toronto has been set at 1.1 C deg (2.0 F deg). It may seem larger to some casual observers but the city occupies a coastal plain beside Lake Ontario (the elevation of the weather station is around 100 m asl), and some rural stations near Toronto are considerably higher in elevation, so that partly accounts for the differentials they show, even with no city there, the Toronto City location would be warmer than those places by some 0.5 C deg at least. Of course the 1.1 C deg is an average for all weather conditions and the actual magnitude of the heat island is considerably larger when it's intact, strong winds reduce it to almost zero and Toronto is a relatively windy location. A calm clear night can be impacted by a warming of more than 3 C deg in the urban area and the magnitude of the heat island is considerable almost out to the suburban-rural boundary as shown by data from North York, a mid-town location in a secondary city centre about 7 km north of the downtown Toronto location. I have estimated the NYC urban heat island at about 1.5 C deg overall, and as New York was already a large city in 1869, it probably began some time before the temperature series, whereas Toronto was only extending much beyond the university campus around the 1870s so that my assumption is that the heat island began around 1881. For each location I have reduced temperatures by 0.1 more for each decade starting with 1881-90, and ending that increment after 1971-80 as the heat islands were probably fully formed by then. As cities grow larger their heat islands grow very incrementally and the main increase is areal spread. Hoping people find these data sets to be both interesting and useful, but even one in the absence of the other would be good. My goal is to create parallel data sets of similar value (if not longevity) to those such as the C.E.T. and E.W.P. records. This is why I have applied the u.h.i. corrections because otherwise the raw data are not directly comparable. There is probably some fine tuning that could be done in terms of applying different values of u.h.i. to dry, intermediate and wet months (figuring that dry months have a relatively large warming effect due to frequent clear skies). An excel file developing graphs and other tables to complement this thread will be made available shortly, just waiting for the end of the year 2020 to finalize those entries. I have recently finished proofing and expanding the Toronto files, and I have a NYC excel file under development that may be ready to share around March 2021.

Table 2j: Comparisons of NYC and Toronto monthly data, Annual means, after heat island corrections In every case, both temperatures in the annual pair have been adjusted by the same amount as explained earlier. Therefore the last entry "diff." remains unchanged. Values and ranks can change. Toronto ranks that fall on opposite side of the warmest/coldest ranks compared to NYC are shown with colour code. Blue in the left column means Toronto's rank is nnth coldest, red in the right column means Toronto's rank is nnth warmest. Where no colour code is shown, the Toronto ranks are from the same half of the data for 152 years.

========================================================================== Toronto median for adjusted annual means is 7.805 (7.82 is 77th warmest, 7.79 is 77th coldest). NYC median for adjusted annual means is 11.58, three are tied at this value (t77 warmest, t76 coldest) To read the NYC values in descending order throughout, move down the left table then up the right column. ================================================================ In the first table of annual means for NYC vs Toronto (raw values) we compared the annual maxima. This table shows the winter minima for each winter since 1869-70 at NYC. The data are arranged by years with the same minimum value from coldest to mildest. Where tied the order is reverse chronological since later winters are fighting a larger urban heat island effect. All data in this table are in F deg (Toronto measured in that system to 1977, so only readings 1978-2022 have been converted from Celsius observations, the rest are as observed in F). Dates are shown, and the corresponding Toronto values. When the dates are not close, comparative values on closest cold minimum dates are shown (sometimes in smaller print size). A list of differentials tracks the temperature differences in these very cold spells, with Toronto usually the colder of the two. If two differentials are shown, they apply to the lowest value at NYC then the lowest value at Toronto. One exception is the few cases where NYC had two tied values and Toronto had one corresponding to one of those, so the two numbers in this case are both NYC minimum differentials vs two Toronto equivalents. A negative differential means NYC was colder (see 1879). The first winter of 1933-34 has two remarkably cold days and has two entries with notes, then the rest of the table follows, any further notes will be found after that table. Ranks are for the 155 compared winters (1869 to 2023), ties are broken by latest tied value having coldest rank (e.g., for NYC, 1898-99 ranks 4th, 1881-82 ranks 5th, 1880-81 ranks 6th, although all tied at -6 F.) It should be noted that these comparisons are for raw data unadjusted, comparing winter minima factoring in the urban heat island is complicated because some cold nights have strong winds and reach almost the same temperatures as would be the case in the absence of a large city, while others are nowadays probably 5 C (9 F) deg warmer at least. A preliminary value for winter 2022-23 has recently been added to the table. _________________________________________________________ _ Winter ___ MIN ___ Date(s) NYC ____ Tor min, date(s) __ diff (similar date) _ ranks 1933-34 ___ --15 ___ Feb 9* __________ --22 (Dec 30)* _____ 6 (for Feb 9) __________ 1, 2 also 1933-34 _--6 ___ Dec 30 ____________ --21 (Feb 9) _________ 16 (for Dec 30) _______ (not ranked) __ *This winter also produced a very cold December (1933) reading which is __ added to the table in italics.

(f) Although the two dates are close, it appears there were two cold highs separated by a snowfall. _____________________________________________________________________ 28 winters (1841 to 1868) had Toronto minima but no NYC comparative data. To adjust the ranks of the 155 Toronto winter minima listed in the table, apply these corrections: (1) 2 winters (1858-59 at -27F, 1854-55 at -25F ranked 1st and 2nd coldest ahead of 1886 which moves to 3rd). (2) Winters with -22 min add 2 ranks, none in the earlier period tie them (2nd 1933-34, 3rd 1913-14 go to 4th, 5th). (3) One winter (1860-61) tied with three others at -21 F, as the earliest, it would rank 9th (the others move from 4th-6th to 6th-8th). (4) Two winters (1862-63, 1856-57) tied 1917-18 at -20, the latter moves to 10th and 1862-63 ranks 11th, 1856-57 ranks 12th. (5) 1855-56 tied 1911-12 (-19), the latter moves from 8th to 13th, and 1855-56 is then 14th overall. (6) No early winters finished at -18, the four in the list move from 9th-12th to 15th-18th. (7) 1845-46 (-17) joins four others at 13th-16th in the list, these move to 19th-22nd and 1845-46 then ranks 23rd overall. (8) 1867-68 (-16) joins five others at 17th-21st in the list, these move to 24th-28th and 1867-68 then ranks 29th overall. (9) 1863-64 and 1851-52 (-15) join three others at 22nd-24th in the list, these move to 30th-32nd and the two earlier winters are then 33rd and 34th. (10) 1865-66 and 1848-49 (-14) join three others at 25th-27th in the list, these move to 35th-37th, and the two earlier winters are then 38th and 39th. (11) 1850-51 becomes 47th, after seven others move from 28th-34th to 40th-46th. (12) Winters at -12 move from ranks 35th-41st to 48th-54th. (13) 1853-54 (-11) becomes 61st after six others move from ranks 42nd-47th to 55th-60th overall. (14) 1863-64 (-10) and 1852-53 (-10) become 71st and 72nd, after nine others move from ranks 48th-56th to 62nd-70th. (15) 1859-60, 1847-48, 1842-43 and 1840-41 (each -9) become 84th to 87th, after eleven others move from ranks 57-67 to 73-83. (16) Winters at -8 move from ranks 68-76 to 88-96 overall. (17) 1857-58, 1848-49 and 1843-44 (each -7) become 106th to 108th coldest overall, after nine winters in the list above move from ranks 77-85 to 97-105. (18) Winters at -6 move from ranks 86-99 to 109-122 overall. (19) 1866-67 and 1861-62 (both -5) become 137th, 138th, after fourteen in the list above at 100th to 113th move to 123rd-136th. (20) 1844-45 (-4) becomes 147th after eight others at that value move from 114th-121st to 139th-146th. (21) 1846-47 (-3) becomes 154th after six others at that value move from 122nd-127th to 148th-153rd. (22) Winters at -2, -1, 0 and +1 move from ranks 128-144 to 155-171 overall. (23) 1841-42 (+2) becomes 172nd after two others (both quite recent) move from 145-146 to 173-174, (24) There being no milder readings in those early winters, ranks 147-156 move from 175-184 overall.

Ranking months for NYC with urban heat island corrections This section will follow the same pattern as the Toronto adjusted temperature ranking tables. The comparison of NYC vs Toronto will always involve the same adjustment (in C deg, from 0.0 to 1.1), as explained in the previous section, but the NYC values shown are assumed to contain the equivalent of 0.3 C of urban heat island already established by 1869. The Toronto ranks in this table are for the overlapping years 1869 to 2020 and will be therefore different from table values earlier shown, especially at the colder end where most of the 1840-68 data are located even after the correction. There are exceptions -- July 1868 ranked as high as second in the adjusted values (was third after 2020 took second in raw values). February 1857, March 1842, April 1844 and September 1865 are other rare examples of top third outcomes in the pre-overlap years. ... Because the same deductions were made from all post-1880 data at both locations, the differences in these tables for each month will be identical to the earlier tables for raw data. The ranks will also tend to maintain similar patterns of similarity or differences but exact values there will depend on movement within the tables. Most more recent months tend to drop down about five to ten ranks but sometimes the more extreme values maintain their ranks or only lose one or two spots. As most of the colder months from early in the overlap period were considerably colder than modern cold months, they are more resistant to changes in ranks but the more extreme recent cases do manage to intrude quite far down into the "bottom ten" ranks (these tables follow the opposite order to the last set, and show warmest at the top of each month's list). Table 2f: Comparisons of NYC and Toronto monthly data, Jan to Mar, after heat island corrections In every case, both temperatures in the monthly pair have been adjusted by the same amount as explained earlier. Therefore the last entry "diff." remains unchanged. Values and ranks can change. ______ JANUARY ____________________ FEBRUARY ________________ MARCH Rank, yr, mean__Tor rank, mean, diff__ Rank, yr, mean__Tor rank, mean, diff__ Rank, yr, mean __Tor

NYC (Central Park) mean temperatures adjusted for urban heat island After studying the differentials from Toronto to NYC over time, and considering that NYC was a larger urban area in 1869 than Toronto, and probably had begun to develop an urban heat island, the decision is to adjust the raw data by similar amounts to Toronto, but assuming that the urban heat island was 0.2 deg (C) in 1868, and 0.3 from 1869 to 1880 which years were not adjusted for Toronto. So the adjustments after 1880 will continue at the same rate as for Toronto, 0.1 per decade (starting 1881-90) but all the data in this table should be read as being 0.3 warmer than the non-UHI equivalent. This means that NYC is set at 1.4 for total UHI compared to 1.1 for Toronto. If useful data become available for the same general area before 1869, it is proposed that 1857-68 be raised by 0.1, and 1821-56 by 0.2, to extend the urban heat island adjustment.

Table 2e: Annual mean temperatures NYC and Toronto, with annual maximum at both locations The differentials will be analyzed when this work is completed. At this point I don't have much of an expectation of what if any trends will emerge from this. You can see that some very warm years like 1998, 2015 and 2017 had rather subdued summer heat compared to some middle-ranking years like 1936. The first case of a year with ranks from different sides of the median showed up with 23rd warmest (NYC) 1979, which was 61st coldest of the overlap period for Toronto. All 29 years 1840 to 1868 not in the overlap were colder than 1979, which was 90th coldest (just about on the median which is 91st both ways) from the Toronto data set. Leaving out the non-overlap years will leave years colder than 75th warmest at Toronto on the colder side in this comparison. The differential is highlighted by underlining and colour coding the cases (the Toronto colour code will be blue in these cases and red for any later cases where NYC years are below the median, which is going to fall at 76th place both ways for 151 years of data. Where two different dates have the annual maxima, the corresponding opposites are shown, with a one or two-day extension for NYC allowed as this is quite frequently the time differential found -- however quite a few cases of simultaneous dates occur, for example, Sept 2, 1953 which was the warmest September date at both locations (102, 100 F). If the comparison involves multiple dates, a note is provided. ... A reminder, Toronto temperatures were recorded in whole F deg until 1977 when Celsius readings began. So the conversions are only relevant from 1977 to the present time, the readings cited pre-1977 are as they appear in the former records (and in same format as NYC to that point in time). Dates for annual maxima are coded day - month (e.g. 18 07 is 18th of July). Due to space limitations, later duplicates for NYC are added in the notes, the later duplicates for Toronto appear in the table. Notes start with short bracketed comments, if space insufficient, a letter code links to footnote extensions.

NYC had two days at 94, 13 June and 20 July. On those two occasions, Toronto had 87 F on 12 June and 88 F on 19 July. ... ... The comparison noted for 24 Sept yielded a daily record of 91 at NYC and was Toronto's latest of year annual maximum. (b) 1931 ... TOR had a daily record of 96 on Sept 11th (one of two NYC dates for annual max) and 92 on 6th Aug. NYC's reading of 95 on June 30th was one of the few occasions where NYC failed to reach a temperature set at Toronto during the same hot spell (98 on 1st July) and in fact it cooled off to 92 on that date for NYC. (c) 1979 ... There were numerous minor warm spells at both locations all summer and NYC came close to its annual max in both May and October as well. Overlap was indistinct. During the two warmest spells for TOR, NYC had readings in the high 80s. During the two warmest for NYC, Toronto maxed out near 85 F. (d) 1946 ... This was a relatively cool summer where Toronto had four tied readings of 90 and near one of them NYC was 94. The other three each produced a reading of either 90 or 91 at NYC within a day in each case. Note also in 1946 Toronto had its warmest March reading of 80 F and NYC had 79 deg, but in the very warm March of 1945, NYC beat Toronto 86 to 74 on similar dates late in the month. (e) 1987 ... For the two tied annual max dates for TOR, NYC had 94 on 15th June (96 on 20th) and 95 on 25th July. (f) 1970 ... NYC also had 94 max on July 18, Aug 13 and 15. Near those dates, Toronto had 87 (July 17) and 88 (Aug 14-15). (g) 1899 ... TOR had 87 on June 6th and also July 26th corresponding to the NYC annual maxima. (h) 1909 ... NYC had 90 max on Aug 25, Toronto had 90 on June 30 and 93 on Aug 8 both cases a few days later than NYC annual max ties. (i) 1927 ... NYC was not in warm air mass when TOR hit annual max on June 30 (offshore low, temps 69-73). TOR had 91 on July 12th, 84 on July 28th, and 88 on Sept 15th. (j) 1918 ... August 1918 had two very hot days at both locations. For Toronto, the 13th provided the annual max and record high for August, 102 while for NYC it was the 7th at 104 that was August's hottest day. Toronto's max that day was 101 F. For NYC, the second peak only registered 96 on the 14th. (k) 1889 ... TOR had 80 on May 8th, and was not in warm air at all when NYC hit 91 on June 9th (65 on June 8th). (m) 1895 ... During the five-day hot spell May 30-June 3, Toronto set two of its three tied annual maxima (93) and NYC had 96 on May 31, June 1 and 2 ... NYC was also 93 on Sept 12, after Toronto's third tied max on Sept 11. ... Toronto had 89 on Sept 21 before NYC hit 97 on 23rd for its annual maximum. --------------------------------------------------- Differentials of NYC vs Toronto on annual basis This table shows the differences in annual mean temperatures each year (C deg) 1869 to 2019.

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 157 years are being compared, ranks run to 79th warmest or coldest. April does have overlapping ranks at the median for Toronto. With 2025 now added, the group at 6.9 (four years) are t79th 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 10.64, t77th warmest 10.67. May for Toronto now has a median of 13.0 (five tied 76th warmest to include 79th warmest/coldest and tied 78th coldest). The median for NYC is now 16.61, t78th warmest and t79th coldest (1946,95). June has a large group that straddles the median, for Toronto 18.7 is both tied 76th warmest and 73rd coldest with a total of nine years included. NYC ranks t75th warmest and t77th coldest are equal and this total of six years also straddles the median which is now between 78th warmest and 78th coldest.

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).

_-1.11 __04 _-5.4__4.3 ============= For January, the average differential in 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.

NYC data section now begins ... Comparisons with NYC (Central Park) 1869-2024 I have obtained the monthly and daily data for NYC (Central Park) which runs from 1869 to Apr 2024. 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.

That means that the year 2020 is tied with 2012 as joint warmest on record (57.3 F, 14.06 C). Another data point challenged in Dec 2017 remains as before for now. The CF6 lists 35.0 F and the linked data 33.4 F for that month. Our supporting data base shows 35.0 also. So we're not sure if this one will change eventually or not, if it does, the tables will be changed accordingly. ______________________________________________ The temperature averages are derived from this source (in F deg) and as of Mar 8, 2021, all values above are in this link (in F deg).

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) ___

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.

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.

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 and 3rd warmest autumns (2021, 2024) and 7th warmest winter (2022-23), tied warmest winter (2023-24), 4th warmest spring (2024) 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) _ now also spring due to 2024. 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 __ 21_____________ 0___________________5_______11____11________ 7__ 04_8__3 9____1,2___ spring summer ___________45______________________9 7___________ 2__3_5___________________1__07_540_summer autumn _________(59)____29 _________0____________2______________4___ 5__________7__ 11 11_6183 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.

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).

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.

Summary of Dry Spells 1840 to 2024 _______________________________________ 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.

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).

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 76 in 70 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.

<<< 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.

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.
