Log of Record Lows 1901-1910 For this and later decades, a log will be posted for each year, with a brief commentary, showing the new record low maxima and minima established (or tied with starter era or previous years). The count for the year will be tracked in the last two columns, the first of those two columns will track the low maxima (set in year, eventual end of record) and the second will track low minima (set in year, eventual end of record). Values in brackets were not records at the time and are shown to give context. To make the tables more readable with extra columns added, these context values are always on the same dates as the records, in some cases there may have been more extreme (but still not record) values on adjacent dates (and in other cases, these more extreme values are records so are also in the tables). Where record low max and min are set on the same day, if space permits, the two records are given their appropriate former and future reference points, unless it becomes too crowded due to ties, then a second line is used. This simultaneous readout will be apparent in two ways -- no brackets for either value, and two sets of count values. Ties beyond the starter era do not count forward (for example, if 1903 ties 1888, that is given as a count of 0.5 for 1903, but if 1947 also ties, then in 1947 the count becomes 0.33 but remains 0.5 for 1903 in terms of records established. If it is a surviving record then that would alter the count for 1903 (and 1888). The annual commentaries will show the gradually decreasing expected number of established records which was always 11.4 in the starter era for both types of records. It will now start to decrease gradually ending up at 2.4 by 2022. That latter figure is always the expected number at random for surviving records of either type. A decade summary will give the updated totals to the end of that decade, comparing trends to those established in the starter era (see last comments in previous post). 1901 _ The first year of the decade continued the trend of the late 1890s in being a rather warm year with not that many record lows. In fact the counts were just 5.33 and 2.0 for low maxima and low minima. Of those, 3.0 low maxima survived (two are ties, so four dates) and neither of the record low minima survived. There were also no "coldest since" record lows. (expected records set in the year down to 11.1). The extinction date for record low minima was June 17th, 1914. This was the earliest extinction for any year as this was the first year since 1870 not to retain any, and the 1870 extinction date was Feb 22, 1918. However 1908 set no record lows so was out before 1901. The minimum now closest to the eventual record low is the June 17 record (53F) which remains 2 Fdeg higher than the eventual mark.

Even so, most of the numerous 1903 records (beating the starter era) were eventually replaced. Therefore from a count of 16.5 (not equalled since 1903), the eventual count is just 5.25. That is nevertheless higher than all subsequent years except 1917, 1918, and 1963. The low minimum count during the year was 7.0, of which 2.5 have survived. There was just one "coldest since" a record minimum, 36F on Oct 25th part of a five-way tie after the 1879 record of 29F, leaving a count of just 0.2. While June was exceptionally cool, the rest of the summer continued to set occasional record lows.

From an original count of 7.5 low maxima, 4.0 have survived, and from the original count of 4.083 low minima, 2.0 have survived. The expectation at random has now dropped to 10 records per year (366/36). In addition, there were three instances of a minimum being "coldest since" a previous record low. These were Feb 16th (2F coldest after record 1F 1888), Apr 17th (30F was coldest after record of 27F 1875), and Apr 20th (27F was coldest after record of 24F 1897); in addition to those, 3F on Jan 18th was coldest between 1875 (1F) and 1982 (0 F), and 2F on Jan 19th was coldest between 1875 (-1F) and 1994 (-2F). The count for the "coldest since" stat is 3.0 but was 5.0 in 1981.

There was a "coldest since" record set on Dec 8 when 12F was coldest since the 1882 record of 10F. 1906 was the second year in the data set (after 1890) not to retain any record low maxima. Its extinction date of Oct 11, 1951 was third earliest after 1890 and 1908. Also, 1906 is the third year to have no surviving record lows after 1870 and 1901. It has the third earliest extinction date for those, coming on Dec 7, 1926, and also 1908 set no record low minima so was first "out" in that regard.

The closest any minimum of 1908 came to an eventual record low was 5 deg (also Aug 29). Meanwhile, the year set 2.83 record low maxima, of which none remain as eventual records.

Not one year produced the random expected number of minimum records, and only one (1907) retained more than one would expect at random (3.7 vs 2.4). 1903 had a prolific production of low maxima. In the decade, there were 58.0 record low maxima set, of which 20.283 have survived. A few of those set replaced earlier values from this decade so it was not quite a case of 53 starter records falling. Then from 30.92 record low minima, just 11.7 have survived (35.7%). The number of coldest since values is 5.7, bringing the cumulative total to 35.93. __ Log of Record Lows 1911-1920 __ 1911 _ Despite several very warm intervals including most of the early summer, as well as December, 1911 also produced a robust set of low records. There were counts of six of each type set during the year. Five of the six low maxima have survived. This is the second highest survival rate (83.3%) for any year 1869 to 1916 (1878 had 87.5%). Only 1.833 record low minima have survived. There was also one "coldest since" a record low minimum, on May 3rd, when 37F tied 1877 as coldest since the record set in 1874 (33F).

January 1912 was one of the coldest months in the region generally. Parts of the summer were also anomalously cool. Despite that, only 2.5 low maximum records were set, of which only 1.0 has survived (8F on Jan 13th). The count of record low minima was considerably larger at 5.75 which is closer to the random expectation now having fallen to 8.3 (366/44). Of those, 1.833 have survived One later tied in 1914 was also on Jan 13th. September 30th (39F, also lowest for month) remains untied, and August 5th (57F) has been tied twice. In addition there were three "coldest since" record low minima during the year. These were on Jan 6th (6F later tied in 1996 and 2018, coldest after record of -2F set in 1896), -1F on Feb 11th (coldest since joint record of -2F in 1885 and 1899), and Aug 4th (57F later tied by 1951 and 1964, coldest since 1886 56F) for a count of 1.667 for the statistic.

Cold spells were brief and only two low maximum records were set, 20F on March 7th which has survived, and a third tie of an earlier record (39F) on Nov 11th which was later broken. The counts for low maxima were therefore 1.33 and 1.00 (surviving). From 4.5 low minimum records only one (May 11th, 36F) has survived. In addition there were three "coldest since" record low minima during the year. These were on Mar 7th and 8th (both 12F coldest since 7F in 1890 (this 12F tied in 2007) and 8F in 1883, untied since), and also 45F on Sept 15th, coldest since record of 44F in 1873. (count 2.5) ... There was also a reading of 47F on Sept 14th which was the coldest minimum between tied record lows of 46F from 1911 and 1975 and colder than any others on that date besides those two tied records.

From a count of 7.0 low maxima, 2.67 have survived. More impressively, from 14.75 record low minima, 8.83 have survived. Both of those counts have not been equalled since 1914, the original count (14.75) ranks 11th behind ten starter era years, but with the expected number down to 7.9, it was ahead of several of those in terms of ratio to expected (although two more recent years have higher ratios, 1940 and 1963). The more recent year with the closest number of eventual record low minima is 1919 (7.0) with 1963 at 6.5. There was also a large count of "coldest since" record lows, with eight producing a count of 5.0. That is the highest such statistic so far although it will be surpassed by numerous later years, the first of them 1933.

During that interval NYC had its lowest maximum and second lowest minimum on Dec 30th (2, -13). Feb 9, 1934 was -15F. As noted elsewhere a colder day than these might have occurred on Jan 22nd, 1857 before the Central Park records began. During the year, there were 8.83 record low maxima (the highest value for any year 1917 on, with 1940 at 8.0) of which 7.0 have survived. That number of eventual records is also highest for the interval 1895 to present, and ranks tenth behind nine starter era years. It was also a better survival rate than any year so far except 1878 and 1911, and the best survival rate for any year that set more than eight records. From the original 8.167 low minimum records, 6.33 have survived. That is slightly behind 1919 (7.0) and tied with 1926, as second highest after the 1914 production of 8.83 (see 1914 discussion for where that ranked relative to previous years). In addition, there were seven "coldest since" record low minima, with a count of 5.0.

The total number of low maxima set during the decade was 51.75, of which 33.5 have survived. The first of those stats is below random expectation while the second is above by almost half. There were 78.25 record low minima, close to random expectation (77.3) and of those, 41.58 have survived. That brings the total from 1869 to 1920 to 202.48. That indicates about 180 cases that could have a "coldest since" (as later ties would be excluded) and during the decade there were 24.25 of those, for a total so far of 60.18 set (about one-third of the possible total). __ Log of record lows 1921-30 __ 1921 _ This was a relatively warm year without significant cold spells, and the production of cold records was low. From a total of four record low maxima, one has survived. And there was just one record low minimum which was extinguished on Aug 15, 1963. Thus 1921 becomes the fourth year to retain no record low minima (joined 1870, 1906, 1908). The production of 1.0 during the year was tied second lowest so far (1908 had zero, 1906 and 1910 also had 1.0). There was also one "coldest since" a record low minimum, with 7F on Dec 22nd the lowest reading after the record of 4F set in 1872.

From 2.0 record low maxima, 1.5 have survived. And from 5.83 record low minima, 5.33 have survived. That survival rate of 91.4% was second only to 1910 to this point in the data (100% but from just one survivor). High survival rates became more and more common after the next 100% case in 1932 (which preserved all of its 3.5 count). The first year to preserve all records with a higher count than 1930 was 1976. Only 1940 (5.5), 1963 (6.5) and 1976 (6.0) had more surviving low minimum records than 1930 in the interval 1927 to 2021.

Slight declines in totals from the previous decade would therefore be expected (for records set during years, the number of surviving records is always constant at 2.4 per year). From a total of 34.5 low maxima set, barely half the expected number, the number of survivors is 17.58. The total number of low minima set during the decade was 60.25, of which 34.7 have survived (random expectation for that is always around 24 per decade). The decade had a total count of 26.75 "coldest since" record low minima, and the total count so far is 87, against a total of 237.2 record low minima. Since some of that count would involve later ties, which would remove years to 1930 from being eligible to set "coldest since" records, the ratio is more realistically 87.1 for about 200 or so. So what we can conclude is that by 1930, about one quarter of dates had seen both their record low minima and the coldest value that would occur thereafter. Another quarter to third of dates had seen their record lows but not yet the coldest since. And about 40% of dates had not seen their record low yet by 1930, or at least had a tie of an existing record low yet to occur. __ Log of Record Lows 1931-40 __ 1931 _ This was generally warm year with few days below normal, let alone close to record cold values. An interval from May 12 to 14 is shown but none of these cool readings were quite records. From the one record low maximum set on August 11th, the eventual count is 0.33 after that was tied in 1933 and again in 1962. The count of one record low maximum was third behind 1906 and 1929 (tied at 0.83) so far; the first year to have no record low maxima was 1936. There was only a count of 0.5 record low minima (May 23rd, tied 1929) which only survived to May 23, 1935; only 1908 (no record low minima) had a lower total within the year to this time, and only 1870, 1901, 1906, 1908 and 1921 had zero survivors before 1931 joined the list. Of those, 1870, 1901 and 1906 had earlier extinction dates and were all at zero before 1931 started (1908 had none to go extinct). Also, there was one "coldest since record low" value for minima, as shown below: Coldest since _____ 1931 value __ tied by ___ count Nov 7, 1930 (29F) ______ 30 _____ -- -- ______ 1.0 (records for 1931 ...)

March had some quite cold days that are shown in more detail as several near-records occurred as well as one actual one. There were brief cold spells otherwise, and July was rather cool but set no records. Nov 27th was a particularly cold day but the cold was not sustained and it was very mild late in December. From only 1.5 record low maxima, the surviving count is 0.5. From 3.5 low minima, all have survived, making this the first year to achieve that status (100% survival rate). The tied record (Nov 27th) equalled a mark set earlier in 1898, otherwise the three records are all in the spring to early summer. In addition, there were two "coldest since" record low minima, and a count of 0.83 for those: Coldest since _____ 1932 value __ tied by ___ count June 19, 1920 (52F) _____ 54 _____ 2022 ____ 0.5 Nov 28, 1930 (15F) ______ 22 ____ 1936,51 __ 0.83 (also coldest 19F between tied record lows Nov 26 1880, 1938 of 16F) (records for 1932 ...)

The autumn and December were more variable and had frequent cold spells. What kept the count down somewhat was that 1933 tended to follow the path of earlier extreme years for cold rather than hitting easier stretches where its temperatures would have set more records. Some of these near misses are added to the table. From a count of 4.0 low maxima, the eventual count was 2.33. Then from 6.083 record low minima, the count was 3.5. There were nine "coldest since" record low minima, and a count of 6.533 for that statistic. This is the highest count so far and later surpassed only by 1940, 1967, 1976, and 2018 (thus in 5th place overall).

This set a number of records including the lowest minimum temperature (-15 F) of the data series on February 9th. Temperatures in upstate New York were below -40 in this extraordinary outbreak, and Toronto also had some of its lowest temperatures in a longer data set. The rest of 1934 became rather warm and some parts of the summer were extremely hot. Overall, this led to a total of 3.5 record low maxima, all of them retained at the end of the data. This was the first year to manage the perfect survival of its record low maxima (1910 had done it for low minima). It would happen numerous times later since those records were more and more unlikely to be broken. Also, the year set 5.75 record low minima (now higher than expectation as that had fallen to 5.5); 3.5 of those were also eventual record lows.

It held a similar status to 1934 in preserving all of its 4.0 low maximum records until 2019 tied Jan 31st (16F) and reduced the survival rate to 87.5% (3.5). There were only 1.5 record low minima, of which none have survived. The extinction date was Oct 8, 1988.

Despite that, 1936 became the first year not to set a low maximum record during the year. At that point, The closest readings to records (and all but the last mentioned instance of this still applies) were 29F on Nov 27th, one degree above the tied record of 28F (1898, 1932), and two instances of a 2F miss (18F on Feb 19th, record 16 from 1903, and 66 on June 13th, record was 64F from 1875, 1924, later fell several times ending up 55F in 1982). In 1936, none of the earlier years that would reach extinction had done so, 1890 would join it in August, 1937, and 1939 also set no low maxima, while 1908 went extinct in 1940. 1906, 1910, and 1922 went extinct later. The year was far more productive in low minima, setting a total of 6.167 records of which 5.0 have survived. At random by 1936 we can expect 5.4 records per year (2.4 survivors).

(from historical weather maps). 1937 _ The year started mild and then became more average with few large departures from normal in either direction. From only 2.5 low maximum records, 0.83 is the count for surviving records. From 1.2 record low minima, none have survived. The extinction date was September 18th, 1990.

Cold spells were frequent and sometimes quite prolonged. April and October were particular cool months and the summer while it had a few hot days was often quite chilly. From 8.0 low maxima, there were 5.0 surviving records. The count was the highest since 1917 (8.83) and has not been surpassed since 1940, while the eventual count was the highest since 1918 (6.0), and second only to 1962 (5.33) while tied with 1945 for years after 1918. From a count of 10.33 low minima, there were 5.5 surviving, again both higher than all years after 1920 (count 11.08) or 1926 for survivors (6.33) except for 1963 (6.5) and 1976 (6.0). The expected number of records within the year has fallen to 5.1 (surviving always 2.4). In addition, 1940 had nine "coldest since" record low minima for a count of 7.25, higher than all following years except 1967 and 1976 (tied at 9.583). It was also in third place overall as it overtook 1933 with 6.53.

From 27.0 daily low maximum records, 18.0 have survived. At random there were expected totals of about 55 and 24, so these are both below expectation, especially the raw numbers. For low minimum records, 40.03 records in total generated 23.33 eventual records. These are both closer to random expectations. The decade had a total count of 30.867 "coldest since" record low minima, and the total count so far is 117.8, against a total of 260.53 record low minima. Since some of that count would involve later ties, which would remove years to 1940 from being eligible to set "coldest since" records, the ratio is more realistically 118 for about 230 or so. With 1940 close to the halfway mark of the data (currently that would be mid-1945) over two thirds of the days of the year had seen at least some if not all tied eventual record low minima, but only one-third had seen the coldest since that record (a few because there would be a later tied value). __ Log of Record Lows 1941-50 __ 1941 _ This was a generally rather warm year but March was quite cold, and there were brief cold spells at some other points. March did not manage to set any records, the 17th had a maximum of 28F but that was four above the 1916 record. The records set (in the summer despite generally warm weather) were few in number. From a count of 2.0 low maxima, none have survived. The extinction date was July 4, 1978. Also, the 1.0 record low minimum in August did not survive. The extinction date was August 14, 1964. 1941 thus became the fourth year to have no surviving low records, either maximum or minimum. 1906 had already reached that status in 1940 and 1908 would do so in 1951 (but after 1944). The next year to go "extinct" in both categories would be 1944 which lost its only record (a tied minimum) the following year (June 5, 1945). Otherwise there are seven others all after 2000. So 1941 had become the fourth such year before any of those happened (some set no records in either category). There were also two "coldest since" record lows with a count of 1.33.

There were no record low maxima (the third such year after 1936, 1939). The closest approach (valid in 1944 and in the first two cases still valid) was within 3 F deg on April 15th (44F), April 24th (47F), and June 4th (67F) -- the last of these was removed from that stature the next year when 1945 blew away the record with 52F. For record low minima, the count is a mere 0.5, achieved by a tied record on June 5th which was extinct the following year (June 5, 1945). There was just one "coldest since" record low minimum that has three ties for a count of 0.25.

The interval from June 1st to 6th was exceptionally cold and set many records including a tie of the monthly low maximum (52F) and the monthly low minimum (44F). The rest of the year was closer to average in general, although sometimes rather cool, and December turned quite cold again but only came within 3 or 4 degrees of existing record lows. From a count of 5.5 record low maxima, 5.0 have survived. In years since 1945, only 1962 has more surviving record low maxima (5.33). The count for record low minima was 4.25, which was only reduced to 4.20 eventually when 1946 joined what had been a four-way tie for the record on June 2nd. In addition, there were four "coldest since" record low minimum values, for a count of 2.167.

Another very cool interval was late September before a record warm October. There were 3.33 low maxima with just 1.33 surviving. However the year produced 8.0 low minima and a count of 4.5 has survived.

There were two tied record low maxima for a count of 0.83, of which the surviving count is 0.50. There were no record low minima set during the year. This was the second such year after 1908. The closest approach to a record low minimum was Jan 31st when 0 F was one degree above the 1920 record of -1F. However there were four "coldest since" record lows with a count of 2.33.

Record lows or even below normal temperatures were very infrequent and rarely sustained. There was one tied low maximum which was 74F on July 17th, and this both tied 1873 and was further tied in 1962 before the extinction date of July 17, 1992 (72F). 30F on Nov 27th was not a record (28F in 1898, 1932) but is now tied with July 17th as being closest to an existing record low maximum in 1949. The count of 0.5 was fourth lowest so far, after three years with no record low maxima (1936,39,44). The production of record low minima was equally sparse, with one record but that has survived (55F on August 20th). There were also two "coldest since" record low minima, with a count of 1.25.

A few days in the summer and early autumn were cold, but from October to December it was once again often warmer than average. From just 1.5 record low maxima, the count was 1.17 for surviving records. From 5.45 record low minima, the surviving count was 2.17. Only 1963 (7.5) and 1976 (6.0) would have more record low minima in years remaining. By 1950, the random expectation was 4.5 records.

Summary of records set in the decade 1941-50 The pace of record setting continued to fall further behind random expectation in both temporary and eventual cold records. From 21.17 daily low maximum records (47 expected at random), 13.33 have survived (24.1 random). For record low minima, 27.57 records resulted in an eventual count of 17.07. The decade had a total count of 19.17 "coldest since" record low minima, and the total count so far is 137, against a total of 277.6 record low minima. Since some of that count would involve later ties, which would remove years to 1950 from being eligible to set "coldest since" records, the ratio is more realistically 137.3 for about 245 or so. About 60% of record lows (some not yet fully set) still have a "coldest since" in the future as of 1950. The pace of this statistic will remain modest in the 1950s but will pick up considerably after 1960. __ Log of record lows for 1951-60 __ 1951 _ This was a generally rather warm year with limited cold spells, the most significant in mid-June and early November. There was only one record low maximum, 48F on October 11th, and this has survived to the present. It makes 1951 the third year to have full survival of its record low maxima (after 1934, 1946). The closest candidate for a second low maximum was Dec 16th with 20F, just one degree above the 1886 record. From 1950 to 1980, all days within 1F of a record low (of either type) will be listed (some minima will also appear in the "coldest since" table) as it could be argued that the urban heat island makes them climatologically equivalent if not more likely in the absence of the heat island. This criterion will be raised to 2F for 1981-2022. June 14th (61F) was two degrees above the 1907 record (and min 53F four degrees above a record), and June 30th (71F) a similar differential of 2F but that would increase to six degrees in 1967. The year also had only three record lows for a count of 1.83, and the eventual outcome of 0.33 (56F on Aug 5th tied two earlier years). The low on Aug 4th was also both a "coldest since" and within 1F of the 1886 record. Aug 6th (58F) came within two degrees of the record low minimum, as did Sep 8th and 30th (see below). There were seven "coldest since" record lows, for a count of 4.833.

The record lows in June preceded some record heat and this is as close as record lows and record highs have appeared in the NYC data. From 2.17 record low maxima, the eventual count is 0.83. May 20th (54F) was within 1F of the existing record but that increased to 3F in 1957. There was one record low minimum during the year, a tie with 1940 producing a count of 0.5 -- this has not survived and the extinction date was Oct 20, 1972. No other maxima or minima were within 1F or 2F of existing records.

There were two record low maxima, each tying a previous mark, and one has survived (counts 1.0 and 0.5). There were two record low minima and both have survived. That makes 1953 the fourth year so far to manage 100% retention of its record low minima. In addition, there was one maximum within 1F (on May 30) although that has since risen to six degrees above a new record set in 2021. The maximum noted in the table for June 13th was two degrees above the existing record (then 61F in 1941) and later rose to eight by 1982 (55F). Also there was a minimum on Oct 8th one degree above the existing record, now three above a later record. There was one minimum on Aug 2nd (59F) two degrees above the record low (57F in 1875) and not a "coldest since" as that had been taken by 1924 with 58F. And there were two "coldest since" record low minima, with the count 1.5.

There were two record low maxima (count 2.0) of which one (Sep 15th, 57F) has survived (count 1.0). Dec 7th (28F) came within two degrees of the 1869 record low maximum. The previous day (25F) had been three degrees above the record value. From three record low minima with a count of 2.5, the surviving count is 1.5.

With that one record low on Feb 3rd, the maximum (17F) was within 1F of the record (16F, 1917). June 9th (58F) was also within 1F of the 1916 record of 57F and the minimum (51F) was also 2F higher than the 1913 record. On Dec 22, the maximum of 22F was within 2F of the record set in 1921, but later with a new record in 1989 (18F), this rose to 4F. June 26th had a minimum of 58F, 2F above the record. Sep 8th and 15th were also 2F above existing record lows (the 15th would later fall to lower values). In addition (including Sep 8th and Nov 29th) there were three "coldest since" record low minima for a count of 2.17. A coldest since (8F) shared with 1996 was removed on Feb 4, 2023 by a colder reading in 2023 (3F) after the record low (0F) set in 1886 and 1918.

The spring and summer were particularly cool relative to normal. July 6th (max 61F) was the coldest July daytime high and had one of the largest margins over second coldest (10 F deg). From 3.5 low maxima, 2.33 have survived. In addition, seven days, May 17th (54F) and 18th (55F), June 20th (66F), July 5th (64F), Aug 20 (72F)* Sep 28th (57F)* and Nov 10th (40F) had maxima within 2F of records (the two marked * of these changed to 4F with lower records in 1990 and 1984). And from 3.33 low minima, 2.0 have survived. The low on May 8th (37F) was within 1F of the 1947 record and has slipped to 2F after 2020 set a lower mark. Lows on May 24th (44F) and 25th (42F) were also within one degree but the first of those later rose to 5F above the new 1963 record. The minimum of 58F on July 31st remains 1F above the tied record values. The low of 41F on Sep 21st remains 1F above the 1871 record. A low of 29F on Nov 11th was 1F above tied record lows but this changed to 5F in 2017. In addition, six "coldest since" record low minima produced a count of 3.17, details follow: Coldest since _____ 1956 value __ tied by ___ count May 25, 1925 (41F) _____ 42 ______ 1967 _____ 0.5 July 22, 1871,90 (58F) ___ 61 __ 1923,29,44 __ 0.75 July 31, 1895,1914 (57F) _ 58 ______ -- -- ______ 1.75 Sep 8, 1871 (52F) _______ 54 ____five others _ 1.92 Sep 21, 1871 (40F) ______ 41 ______ -- -- ______ 2.92 (records for 1956 ...)

There were only 2.0 low maximum records with 1.5 surviving. The maximum of 47F on Oct 26th was within 1F of the record but that changed eventually to 8F after a much lower value in 1962. And from 1.5 record low minima, the entire 1.5 have survived (the fifth such year so far). The minimum of 57F on Aug 6th was 1F above the 1869 record. A low of 29F on Nov 11th was 1F above tied record lows but this changed to 5F in 2017. Also, the minimum of 40F on May 4th was within 2F of the record and qualified as a "coldest since" those tied records. The low of 45F on May 20th was within 2F of tied 1907 and 2002 record lows. The low of 51F on June 9th was also 2F above the 1913 record but that slipped to 4F in 1980. The Sep 28th low of 43F was 2F above the 1947 record (also a "coldest since"). And the Oct 28th low of 35F was within 2F of the records, which changed to 6F in 1976. In addition, there were four "coldest since" in total with a count of 2.33; details follow: Coldest since _____ 1957 value __ tied by ___ count May 4, 1873,1911,17 (38F) _ 40 ____ 1926 _____ 0.5 Aug 6, 1869 (56F) _________ 57 __ 1934,94 ___ 0.83 Sep 28, 1947 (41F) ________ 43 _____ -- -- _____ 1.83 Oct 12, 1876 (35F) ________ 39 _____ 1964 ____2.33 (records for 1957 ...)

Feb 17th had a maximum of 10F which was three above the 1896 record for that date. May 6th (46F) was one degree above the 1891 record and May 15th (51F) one degree above the 1878 record. And 74F on July 14th was only one degree above the tied record of 73F, while 43F on Nov 2nd was two degrees above the record low maximum (41F) from 1875 and 1895. Despite all that, there were no record low minima in 1958. Two now qualify as closest at 2F above existing records. This was the third such year after 1908 and 1948. The low of 39F on Oct 14th was within 1F of a tied record of 38F but that changed to 2F in 1988. The minimum for Feb 18th (3F) was within 2F of the 1896 record but slipped to 3F in 1979. Also the minimum of 29F on Apr 9th was within 2F of the existing record (1885, 1950 tied 27F) but that changed to 4F when 1977 went lower to 25F. The minimum of 49F on June 7th remains 2F above the 1879 record low.

There were only two low maximum records set, one a second tie of an earlier record, both having survived (counts for both 1.33). The maximum of 65F on June 16th was also one degree above the existing record but that changed to 3F when 1965 had a lower record value. July 14th (74F) was also 1F above the record low max set in 1884 and tied three times since 1960. Aug 5th (70F) was two degrees above the 1903 record. There was also one low minimum record for a count of 0.5. That record was broken on Sep 17th, 1986. Also the minimum on May 16th (43F) was one degree above the 1878 record. A low of 53F on June 17th was 2F above the 1926 record. The count for seven "coldest since" record low minima was 4.083.

March and December were notably cold months. From 2.5 record low maxima, 1.25 have survived. In addition, March 3rd (27F), March 10th (30F) and March 26th (36F) were all one degree above existing record low maxima, although March 10th slipped to 2F above the 1987 record. 71F on Aug 19th remains 1F above the record (1881,1946 tied 70F). Aug 5th (70F) was two degrees above the 1903 record, and Nov 7th (43F) two degrees above the record (four years tied). Also, from 4.0 record low minima, 3.0 have survived. The minimum of 30F on Nov 8th was 1F above the tied coldest records of 29F in 1886 and 2019. There were no "coldest since" record low minima, the first year since 1919 without one.

Summary of records set in the decade 1951-60 The decade had very similar totals to the previous one for daily low maxima, and smaller outcomes for daily minima. From 21.5 daily low maximum records (42 expected at random), 13.25 have survived (24.1 random). For record low minima, 17.17 records resulted in an eventual count of 11.33. The decade had a total count of 22.58 "coldest since" record low minima, and the total count so far is 159.55, against a total of 289 record low minima. Since some of that count would involve later ties, which would remove years to 1960 from being eligible to set "coldest since" records, the ratio is more realistically 159.55 for about 260 or so. More than half of record lows (some not yet fully set) still have a "coldest since" in the future as of 1960. The pace of this statistic will pick up considerably after 1960. __ Log of record lows for 1961-70 __ 1961 _ This was a rather average year for temperatures, sometimes rather warm especially autumn. The only prolonged cold spell was mid-January to early February and it was more of a sustained than a record cold. May 27th was an unusually cold day with another morning low record the next day, but it then warmed up quickly. There were only 1.5 record low maxima, 1.0 surviving (May 27th) and no other maxima within 2F of existing records. There were 2.0 record low minima of which 1.5 have survived. The low of -2F on Feb 2 was only one degree above the 1881 record for the date, and for May 31 (47F) there was also a one degree differential. On June 16th the low of 54F was two degrees above the 1927 record, as was 57F on Aug 14th (changed to 3F above in 1964). In addition, there were five "coldest since" record low minima, none of them tied for a count of 5.0.

The summer months were notably cool, especially mid-August. Early May was cold and then warmed to record heat around the 18th-20th. From 6.67 record low maxima, 5.33 have survived, the highest totals in either case this late in the data set (highest since 1940 for records in year and 1918 for records surviving) . Sep 5th (63F) was also just one degree above the 1926 record low maximum. It was rather cold in mid-December with three days within 4 deg of record lows. A maximum of 13F on Dec 31st and minimum of 4F while not close to the 1917 records are the lowest readings on that date since the records were set. By contrast there was only a count of 1.2 record low minima, 1.167 surviving. The minimum of 57F on Aug 10th was only one degree above the record low and, like the minimum of 57F on July 27th which was only 2F above the 1920 record low, both were a "coldest since" while another 2F differential on Aug 9th came between tied record lows. Minima of Sep 20th (47F) and 21st (42F) were both 2F above existing record lows and 31F on Nov 7th was also 2F above the 1930 record ... There were seven "coldest since" records for a count of 4.033.

The year recorded some warm spells too including a very warm October-November period, but other than late March most of the rest of the year trended below average. Much like 1947 both May and September were cold then a more mixed summer and warm October were added. The winter of 1962-63 was severe in Britain but could best be described as moderately cold in eastern North America. There were 3.33 record low maxima which left 3.25 eventual records when one was later tied. Sep 5th (63F) also came within one degree of the 1926 record. No other days came within 2F of existing record low maxima. There were 7.5 record low minima, of which 6.5 have survived. Those are both the highest totals for any year from 1940 (10.33 record lows), or 1919 (7.0 surviving record lows), to end of the data (1976 came close with 6.0, 6.0). Aug 25th (53F) came within one degree of the 1940 record. Sep 6th (49F) came within one degree of the 1924 record. May 2nd came with 2F of the record low minimum as shown in the "coldest since" table. 54F on June 22nd was also within 2F of the 1897, 1940 tied record and 59F on July 4th although that would increase to 4F after 1986. Aug 11th (58F) also came within 2F of the 1962 record. Aug 19th (57F) came within 2F of the 1924 record and appears in the coldest since list. Sep 14th (48F) was within 2F of the 1911 record later tied in 1975. In addition, there were a total of eight "coldest since" record low minima, with a count of 6.33. This is the second highest count so far (1940 had 7.5) and would be beaten by only 1967 and 1976 (both with 9.08), 2018 (6.83) and 1989 (6.5), tying 2000 (6.33).

July was persistently cool but did not venture into record domain. Late August was especially cold and did set records including tied monthly minima on 29th and 30th (50F) equalled in several other years. There were 4.0 low maximum records, of which 2.0 have survived. Oct 4th (52F) was within 1F of the 1883 record of 51F. In addition, June 15th (62F) was within 2F of the 1916 record (later tied in 1971), and Oct 5th (52F) was within 2F of the 1881 record (50F). There were 2.5 record low minima which have left 1.33 surviving. The minimum of 53F on June 16th was within 1F of 1927 record low 52F, and the next day was also within 2F of the 1926 record (both are among the "coldest since" marks below).

There were no record low maxima in 1966 (the fifth such occasion so far), but two days came within 1F of record lows. April 28th (42F) was 1F above the 1898 record, and Dec 3rd (25F) was 1F above the 1886 record (24F) which changed to 2F when 1976 (23F) went lower. From 1.5 record lows, the same count have survived. Feb 20th (8F) was within 1F of the 1950 record low (7F) but this margin changed to six degrees in 2015 (2F).

There were notable cold spells in mid-March and late May. The count for both record low maxima set and surviving is 4.0. This was the fifth year in the data set so far to have a complete retention of record low maxima (it becomes more common after this, with fewer years left to remove any records set, 29 more years appear in the category out of 52 from 1971 to 2022). Four more days were within 1F, Mar 17th (26F), Apr 24th (45F), Aug 13th (69F) and Nov 7th (42F) -- further details in the table. May 26th (55F) was also within 2F of the 1901,1907 tied records (53F), and Aug 25th (66F) within 2F of the 1873 record of 64F. Sep 23rd (59F) was within 2F of the 1963 record of 57F. 1967 also has a full retention of record low minima, scoring three in both records set and sustained. This makes 1967 the first year to maintain all of its record lows in both low maximum and low minimum categories. May 25th (42F) was within 1F of the 1925 record. In addition there were twelve "coldest since" record low minima, for a count of 9.583, tied with 1976 as highest all-time.

Otherwise, cold weather was rather infrequent in 1968, and it was quite warm in both April and October. There were 3.0 record low maxima, with the count 2.5 for surviving records after one of them was tied in 1970. Otherwise, no maximum was closer than 3F to a record then in existence. From 3.5 record low minima, 3.33 have survived with one low already tying an earlier record then being tied again in 1981. Feb 21st (5F) was 1F above the 1896 record (4F) and Feb 22nd (10F) was 2F above the tied 1918 and 1963 record (8F). The minimum of 57F on June 27th was 2F above the 1940 record of 55F and July 29th (61F) was 2F above the 1914 record of 59F.

Both warm and cold spells were brief. Mid to late July was rather cool, and there was a brief cold snap on Oct 23-24 that set records. There was only one tied low maximum for a count of 0.33 which fell to 0.20 eventually with two more ties added. In addition, July 20th (71F) was 2F above the record low maximum of 1869 (69F), and Oct 23rd (43F) was 1F above the 1889 record (43F). The October cold snap resulted in two record low minima which have both survived. There was only one "coldest since" a record low minimum which preceded the two record lows on Oct 22nd.

From 1.5 record low maxima, 1.5 have survived. 21F on Jan 20th was within 2F of the tied record (1875, 1961) but that changed to six degrees in 1994 (15F). June 21st (65F) remains 2F above tied records from 1958, 2003 (63F). There were no record low minima, the closest was 38F on May 7th (within 1 of 37F set in 1891). Also Feb 26th (9F) was within 2F of the tied records from 1928 and 1990 (7F). There were six "coldest since" record low minima for a count of 4.75.

This was largely due to the tallies in 1962, 63 and 68. The output was still not quite up to random expectation however. From 26.83 daily low maximum records (38 expected at random), 21.8 have survived (24.1 random). The latter was higher than any decade since 1911-20. For record low minima, 28.03 records resulted in an eventual count of 23.83. The decade had a total count of 41.7 "coldest since" record low minima, and the total count so far is 201.25, against a total of 312 record low minima. Since some of that count would involve later ties, which would remove years to 1970 from being eligible to set "coldest since" records, the ratio is more realistically 201.25 for about 280 or so. Almost half (163) of record lows (some not yet fully set) still have a "coldest since" in the future as of 1970. The pace of this statistic will continue to run stronger until the 2001-10 decade where it slowed somewhat. __ The rest of the annual logs and analysis continue in the next post __ This is still being fully developed but the records are already shown

Okay, made that change, you are level with the contest consensus rounded off although both named storms and hurricanes are just about halfway from 19-20 and 9-10 respectively, rounding down from 19.4 and 9.4 now. We have passed the deadline as announced, would allow in any forecasts (or late edits) to 06z June 4th at which time contest is closed to further entries.

At the same time it has been record cold in the Pac NW and southern BC, anomalies in WA state were close to -5 F deg. I live near the border north of Spokane and our trees only finished their normal mid-May full foliation cycle today. We can still see snow on top of nearby hills with summits of 7,000 to 8,000 ft. Last week there was still snow on even lower hilltops reaching 6,000 ft. Certainly normal to see snow on alpine slopes around here into July, but these lower hills are usually free of snow by early to mid May. As a result there was no spring flooding at all in the region as a lot of the snow is still up there. In 1948 a similar weather pattern turned very warm with heavy rain, and historic floods hit both the Fraser and Columbia Rivers. It was the end of June last year when we had the unprecedented heat dome and highs around here of 110 F. Hoping we don't see that this summer although even in a normal summer you can expect a few days in the 100-105 F range.

This is sort of like the Brooks Koepka - Bryson de Chambeau thing applied to meteorology. Mind you I am a bit of a Jean van de Velde this year.

Posted a bit early just so that any late entries will find it easier to pick a unique set of numbers (picking a set already taken means you would automatically finish behind that earlier entry in the rankings). You can pick the expert consensus though, they are scored but not ranked in the contest other than to note where they would have finished had they been an actual contest forecaster. The "contest means" shown are rounded off, the decimal versions are currently 19.4 _ 9.3 _ 4.1 (these do not include the expert consensus although they could without any significant changes.) SCORING _ As in past year, the error factor for named storms is 50% as big as the factor for hurricanes and majors. The basic concept is, you start with 100 points, then lose points from this formula: H and M errors are deducted from the formula (E + E^2)/2 ... error plus error squared, divided by 2. For example, your prediction of H and M is 10 4 and the end of season count is 12 5. Your H error is 2, the deduction is (2 + 4) /2 or 3. Your M error is 1, your deduction is 1. So far then you are reduced to 96 points (100-3-1). The deduction for named storm errors is calculated the same way, then half of that calculation is applied. So to continue with the same example, if your forecast had been 22 10 4 and the season count turned out to be 19 12 5, then your named storm error is 3 and your deduction is half of (3 + 9) / 2 or half of 6 which is 3, so your total score is 93 (100-3-3-1). If you do enter between now and end of the day Friday June 3rd, I will adjust the contest means and any other information as required. If you have a forecast entered and want to edit it, let me know. In the absence of further changes, bring on the 2022 season and we'll see how we do.

Snowfall Forecast Contest Departures (errors) _ Probable Final Results (season ends June 30th) This table will track the departures of each forecaster, those which are in italics and underlined are forecasts already passed by actual amounts; those departures (errors) can only increase with more snow. All other departures (errors) can be reduced by new snowfalls. The actual snowfalls are the latest available for each station. A reminder, our contest is based on total winter snowfall, not any portion such as Dec to Mar, so it includes anything that might fall in April and May. The table is now in order of least total departures. _________________________________ DCA __NYC __BOS ___ ORD __DTW __BUF __ DEN __SEA __BTV ___ Total dep (to date -- May 31) _____________ 13.2 __ 17.9 __ 54.0 ___ 32.8 __ 47.1 ___ 97.4 __49.4 __ 9.2 __70.7 RodneyS ________________________ 12.8 __ 25.0 __ 45.0 __ 54.0 __ 42.0 __ 91.0 __ 48.0 __12.0 __ 75.0 RodneyS _________________________ 0.4 ___ 7.1 ____ 9.0 ___ 21.2 ___ 5.1 ____ 6.4 ___ 1.4 __ 2.8 ___ 4.3 ______ 57.7 Roger Smith ______________________17.5 __ 32.5 __ 50.7 __ 44.8 __ 49.5 __107.2 __ 52.0 __10.5__ 82.2 Roger Smith ______________________ 4.3 __ 14.6____ 3.3 __ 12.0 ___ 2.4____ 9.8 ___ 2.6 ___ 1.3 __ 11.5 ______ 61.8 DonSutherland 1 __________________9.4 __ 27.3 __ 44.9 __ 35.1 __ 28.3 __ 84.0 __ 43.4 __ 9.5 __ 71.5 DonSutherland 1 __________________3.8 ___ 9.4 ___ 9.1 ____ 2.3 __ 18.8 ___13.4 ___ 6.0 __ 0.3 ___ 0.8 ______ 63.9 RJay _____________________________ 5.0 __ 20.0 __ 42.0 __ 40.0 __ 34.0 __ 90.0 __ 50.0 __13.0 __100.0 RJay _____________________________ 8.2 ____ 2.1 __ 12.0 ____ 7.2___13.1 ____ 7.4 ___ 0.6 ___ 3.8 __ 29.3 _____ 83.7 wxallannj ________________________12.0 __ 28.0 __ 36.0 __ 38.0 __ 36.0 __ 92.0 __ 41.0 __ 11.0 __ 95.0 wxallannj ________________________ 1. 2 __ 10.1 ___ 18.0 ___ 5.2 ___ 11.1 ___ 5.4 ____8.4 ___1.8 __ 24.3 ______ 85.5 hudsonvalley21 __________________11.6 __ 30.3 __ 33.8 __ 32.7 __ 32.4 __ 94.0 __ 45.0 __10.2 __108.8 hudsonvalley21 __________________ 1.6 __ 12.4 __ 20.2 ____ 0.1 ___14.7 ____3.4 ____4.4 ___ 1.0 ___ 38.1 ______95.9 so_whats_happening _____________16.0 __ 34.0 __ 62.0 __ 41.0 __ 45.0 __ 74.0 __ 36.0 __11.0 __ 91.0 so_whats_happening ______________2.8 __ 16.1 ____ 8.0 ___ 8.2 ____2.1 __ 23.4 ___ 13.4 ___1.8 __ 20.3 ______ 96.1 wxdude64 _______________________20.0 __ 38.0 __ 54.0 __ 52.0 __ 47.0 __104.0__ 58.0 __13.0 __105.0 wxdude64 ________________________ 6.8 __ 20.1 ____0.0 __ 19.2 ____ 0.1 ___ 6.6 ___ 8.6 ___3.8 __ 34.3 _____ 100.5 Tom ______________________________17.7 __ 36.9 __ 46.1 __ 48.7 __ 47.8 __ 94.4 __ 65.2 __ 8.1 __102.2 Tom ______________________________ 4.5 __ 19.0 ___ 7.9 ___ 15.9 ___ 0.7 ___ 3.0 ___ 15.8 ___1.1 ___ 31.5 ______ 101.4 BKViking _________________________ 8.0 __ 28.0 __ 42.0 __ 44.0 __ 25.0 __ 88.0 __ 55.0 __22.0__ 85.0 BKViking _________________________ 5.2 ___ 10.1 ___12.0 __ 11.2 __ 22.1 ____ 9.4 ____ 5.6 __12.8 __ 14.3 _____ 102.7 Deformation Zone ________________ 8.0 __ 18.0 __ 36.0 __ 38.0 __ 44.0 __ 70.0 __ 24.0 __ 4.0 __ 86.0 Deformation Zone ________________ 5.2 ____ 0.1 __ 18.0 ____5.2 ___ 3.1 ___ 27.4 __ 25.4 __ 5.2 __ 15.3 _____ 104.9 Scotty Lightning _________________10.0 __ 23.0 __ 38.0 __ 44.0 __ 38.0 __106.0 __ 49.0 __ 7.0 __129.0 Scotty Lightning _________________ 3.2 ___ 5.1 ____16.0 __ 11.2 ____ 9.1 ____ 8.6 ___ 0.4 ___ 2.2 __ 58.3 ______ 114.1 mean of forecasts _______________12.3 __ 28.4 __ 44.2 ___ 42.7 __ 39.1 __ 91.2 __ 47.2 __10.9 __ 94.2 mean of forecasts _______________ 0.9 __ 10.5 ____ 9.8 ____ 9.9 ____8.0 ___ 6.2 ___ 2.4 ___ 1.7 ___23.5 _______ 72.9 (3rd-4th) ==================================== These departures will continue to be updated but as of May 31st the contest is probably finished. Congrats to RodneyS -- a little more snow at DEN and I could have taken this one.

Thanks, will be updating my files later today to check for any recent record or near-record weeks. The only value added to the tables was a third place mean max of 55.86F for the week of Feb 17-23. No other top three values spotted in any categories since new years. Have fixed that typo where 1953 appeared instead of 1954.

Just starting to work on the table of entries for posting tomorrow, further entries are okay until 18z Friday, so are edits but check my table if you make a really late edit as I may have gone past your entry by then.

___<<< ____________ Annual Scoring Report (Jan-May 2022) _______________>>>___ Total scores for each location, region ... best scores for locations in red, for regions in bold type. With most scores fairly similar in May, there was only one set of changes in ranks; wxallannj dropped from third to eighth, so those who had been fourth to eighth after April are now third to seventh. Normal dropped two spaces as well with both RJay and Scotty Lightning moving ahead, so that Normal is now between 10th and 11th, and also there is a prorated score for Stormchaser Chuck (2985), based on 5/3 times actual score, and with that he would be around the same total as our fourth ranked total. Consensus is now just ahead of third place Tom.

Thanks for all the entries, will be making up a table of entries in the next two or three days. Will informally extend the deadline to 18z June 3rd which is when I expect to have this table ready, if any somewhat late entrants want to join in, or anyone already posting wants to edit, go ahead, I won't be making copies of forecasts until the table is ready. Here are some "official" forecasts that will be scored but not ranked in the contest. NHC _____ 17.5 _ 8 _ 4.5 (median of 14 6 3 and 21 10 6) CSU _____ 19 _ 9 _ 4 (median of 13 6 2 and 16 8 3) TWC _____ 20 _ 8 _ 4 TSR ______ 18 _ 8 _ 4 UKMO ____ 18 _ 9 _ 4 (there are others listed on wikipedia, all in a similar range) The "expert consensus" will be the only one listed in the table of entries, that will be 18 _ 8 _ 4 which is close to all of the above. Storm names available for 2022: Alex, Bonnie, Colin, Danielle, Earl, Fiona, Gaston, Hermine, Ian, Julia, Karl, Lisa, Martin, Nicole, Owen, Paula, Richard, Shary, Tobias, Virginie, Walter. There has been no activity yet. In the eastern Pacific theater, Agatha (cat-2) has come and gone, making landfall west of Puerto Angel, Mexico on May 30th.
