EWP tracker ends its soggy journey at 150.3 mm, provisionally fourth wettest February behind only 2020, 1833, and 1923. Will make no changes to preliminary scoring posted a few days ago, until final value is posted on 5th. 2nd CET and 4th EWP would be the most extreme combined ranking for any month at the warm end, but August 1912 was wettest and coldest. Winter 2023-2024 on this provisional value has a total now of 409.0 mm, ranking 6th behind only 2013-2014, 1914-1915, 1989-1990, 1876-1877, and 1994-1995. Rest of top ten below 2023-2024 now are 1993-1994, 2020-2021, 1868-1869, and 2015-2016. This winter almost doubled last winter (216.3 mm) and was well ahead of 2021-2022 (245.7 mm). 2019-2020 ranks 13th (now) with 1915-1916 and 1959-1960 in 12th and 11th. So we have seen five of top thirteen wet winters in past eleven.

March CET 1981-2010 averages and 1772-2023 extremes all data shown now converted to v2.0 _ 1909 lost two record low daily means (-2.9 4th and tied -2,.8 5th) and both of those were increased by almost a full degree in v2.0. 1875 lost a record high to 2014 on 7th with just a small drop from 10.9 to 10.7. On 18th, 1853 maintained a record low despite rising to -1.1 C, the value attained by 2018 in CET legacy, but it also warmed 0,.1 to -1.0, so continued to be a very close second lowest for that date. 1903 lost a record high to 1927 on 22nd, and 1886 replaced tied 1852, 1945 on 23rd. Otherwise, most of the records are the same for years, and within 0.2 for values in most cases. (v2.0 only began to change legacy values in 1853). --------- (daily record means, 1772-2023) -- (1981-2010 avg) ------ (extreme running means) --- DATE ___ MAX ____________ MIN ___________ CET date,

Another factor that needs to be considered, as I understand it from various links in current discussion, in 1779 CET values are from a single location near London, albeit a London with very little heat island. Now it depends on specific synoptics but quite often London averages nowadays are 1-2 C above CET, not all of it due to urban effect. There would be cold months with s.e. wind flow turning out colder in 18th century London than 18th century central England too, 1779 would not likely be one. Also, CET in this period drops 0.2 for urban effects, so before that adjustment, 2024 was 8.0 not 7.8. If this was a month where the urban effect was not as great as average (clear skies and cold air masses have largest urban heat island effects, 2024 had little of that sort of weather) then it is another reason to say 1779 and 2024 are probably virtually tied. Now it could be that I missed some details about adjustments of London values to overlap with later grids of stations located further n and w. To the point in the previous post, a 31-day interval ending 20 and also 21 Feb averaged 8.3 so that is probably a real indicator of a potential February average of around 8.5 (both shorter and later being factors). It will not surprise this observer if we see an 8.5 February sooner or later. I also think march could go to 9.5 or even 10.0, 1957 was not piling on heat near the end and fell back from around 9.5. Just as a guess, I would expect CET record values by 2050 to be around 8.0 _ 8.5 _ 10.0 _ 12.5 _ 15.1 _ 18.5 _ 20.2 _ 20.0 _ 17.5 _ 14.5 _ 11.0 _ 9.6 ___ 11.8 annual you can see I believe 1833 and 2015 will hold on and the other ten will be broken. I would expect a 14.2 to 14.5 may and a 9.0 Dec in the next 25 years, not records but new second place values. If there is a net-weather in 2050 they can have a laugh at old RJS at that point. (I would be 101 and not likely caring).

The 1961-1990 average CET is 5.7. Oddly the two warmest years were 1961 (8.2) and 1990 (8.3). The 28 years in between had an average of only 5.5 C. The third highest was 1981 at 7.8.

1779 is apparently still on the couch ... a 7.5 (report) for 29 Feb leaves 2024 0.1 short at 7.8. ... (not a prediction, a report) ...

EWP tracker will finish near 148 mm, will wait for table value on 5th to determine winner (Frigid 130 mm, stewfox 166 mm).

7.4 CET and 78.8 EWP. A bit cold to start, higher values later, not a dry trend but could be close to average.

"In terms of where we're at, we're at 7.833C. The record is 7.871C." Just wondering, do you calculate by simple arithmetic of numbers in "mean CET" table or do you look at an overall average of CET max and min values? I came to the opinion that CET tables are based on some kind of calculation of (mean max + mean min) / 2 whereas anything I ever post about CET is done by the simple arithmetic method. I also wonder if they adjust for any rounded daily means (cases with an odd and even digit in play e.g. 7.0 and 1.3). What blunts that problem for CET is a system where they don't round all of these upwards, some are rounded downwards. They could cancel out.

"For crying out loud. I’ve tried to explain, to no avail, that in the past readings were taken just once a day, at 0900. Therefore the readings taken were the max and min over the past 24 hours, no attempt being made to allocate them to 2 x 12 hours, as that would be based on assumptions, not fact. Some sites still use this convention, so all must." So therefore you must believe that this 0900 reading of max goes back to previous calendar day in records (as one obvious example the super hot day 19th July 2022 was presumably recorded at 0900h 20 July although I believe it was already observed at the various sites at 2100h of 19th), and the min recorded at 0900h stays with same calendar day for min. But I believe that CET data (and possibly various stations on 0900 system) are at least reviewed by an observer at 2100 and if temps have been falling between 0900 and 2100 a new daily min can (and certainly should) be recorded. Let's see what happens on 29 Feb, I believe the min observed to 0900 on 29 Feb will be considerably higher than the min observed by 2100h because temps are likely to fall steadily during day and early evening of 29 Feb. What they note in tables as min for 29 Feb could answer this question. Also, I wonder if an actual stakeholder in CET can confirm what happens. If anyone with past success at having e-mails answered wants to give it a go ...

Perhaps the confusion about where they found -0.7 C for a daily in for 27 Feb can be explained by the supporting paper not explaining procedure, I suspect it is actually as follows: readings are taken at 9 a.m. and 9 p.m. of extremes, the lowest value to 0900h of date (in this case 27 Feb) begins at 9 p.m. the previous day (26 Feb) and the value is then checked at 9 p.m. (in case 27 Feb) for the unlikely possibility that a lower value has occurred after 9 a.m., which could happen if colder air arrived after 0900h. If not lower then the first of the two obs determines the daily min. The procedure for max is the opposite, a reading is taken at 9 p.m. which captures a max on most days, then the next one at 0900h following day captures overnight rises in temperature that are applied to the previous calendar day. Just from observing dates of low mins in real time, especially in warmer months with shorter nights, you would always see the lowest values on the day before they actually occurred if the min observation period was 0900h to 0900h, and not on the day that they did occur (around 0400 to 0600h on a summer morning and about 0700 or 0800 even in winter, more frequently than at 0900). In any case I think the daily mins are taken from a period that is staggered 12h (earlier) relative to the interval of the daily max.

EWP at about 140 mm now, will add 10-15 mm more by end of Feb to finish about 3rd or 4th overall. I have adjusted scoring table to 156 mm for an end result, a few scores changed and all but one average error gained another 8 mm from last table's 132 mm setting. (24/3 = 8, everyone in contest so far is given three errors, you get error of consensus + 5 mm if you don't play; you need to be in to get points however). It is not quite official yet but stewfox (166) will probably edge out Frigid (130) and those were the two highest forecasts so all other ranks are already set. I will be third although currently in second until we have a value over 146. I could probably post CET-EWP results today but not sure yet what rank Shillitocettwo will have for a 9.0 C punt that could be second or third, but possibly fourth to about twelfth depending on what final value is. Congrats to syed2878 who is sitting on a sure winner at 8.1 C. (third highest forecast was 7.4 C). This beats the feat of LG back in Dec 2015 when he went 9.0 for a (then CET legacy) 9.7 finish (it was since adjusted to 9.6 in v2.0). I looked back a while ago and recall that record Apr 2011 had one or two close forecasts as well, don't recall who but I think one or two were above the result. We had a larger group error in march 2013 than any other contest.

EWP not to be outdone is also going to have a go at a new record, 117 mm had fallen by 21st, looks to be over 130 mm now, and the Sunday low is going to release a deluge on the southwest; while it's going to be fairly dry apart from that, could see EWP over 150 mm and closing in on third place 1923 (152.7 mm) or even second place 1773 at 158.6 (2020 recently set the record of 169.5 mm). Full top ten can be seen in previous post about a page back now. Will adjust scoring again later, stewfox (166 mm) will move up to first place if and when we pass 148 mm. (Frigid next at 130 mm).

Yesterday's average of 9.6 raises the already reported weekly record by .01 to 10.67, and it creates an even higher 31-day average since 21 Jan was 7.9, raising that from 8.29 to 8.34.

Looking for a top ten Feb EWP now, I just edited scoring back a few days to an expected 132 mm and it could go even above 132, but top 15 now are as follows: _01 __ 169.5 _ 2020 _02 __ 158.6 _ 1833 _03 __ 152.7 _ 1923 _04 __ 143.6 _ 1950 _05t__ 143.2 _ 1977, 1990 _07 __ 142.1 _ 1937 _08 __ 136.7 _ 2014 _09 __ 132.0 _ 1916 _10 __ 131.7 _ 1900 _11 __ 130.0 _ 1848 _12 __ 129.6 _ 1966 _13 __ 129.1 _ 1768 _14 __ 124.2 _ 1925 _15 __ 123.5 _ 1915 (16th is 116 mm which is probably about where 2024 is already)

Feb 1779 is like that friend or relative who asks if they can couch surf while they look for work and years later they are still there.

I just updated previous post tracking a record "warmest week" all within February, the winner is: 01 __ 14-20 Feb 2024 ___ 10.66 (21st would need to beat 14th 9.5 to increase this) now 15-21 Feb 2024 ____ 10.67 (21st was 9.6). Also can confirm a 31-day interval from 21 Jan to 20 Feb 2024 averaged 8.29 above previous record (for 31-days within Jan-Feb) of 8.0 set 14 Jan to 13 Feb 2002. This could increase slightly if today's average beats 7.9 to replace 21 Jan. Note: 8.34 to 8.35 is new maximum value as 9.6 added 1.7 to total divided by 31 adding .05, it just about rounds off to 8.4 now as it's probably 8.35 but below rounding (like 8.348), anyway metoffice probably would calculate it from average max and min and get a somewhat different result, I averaged daily mean CET to get my numbers.

Tracking a new record "warmest week" all within February, the contenders are: __ confirmed after today's update __ 01 __ 15-21 Feb 2024 ___ 10.67 02 __ 22-28 Feb 1846 ___ 10.39 (if 23 Feb to 1 March is taken, increases to 10.53) 03 __ 10-16 Feb 1998 ___ 10.31 04 __ 01-07 Feb 2004 ___ 10.26 05 __ 20-26 Feb 2019 ____ 9.90 (21-27 was 9.87) 06 __ 04-10 Feb 1869 ____ 9.79 (03-09 was 9.77) __ 8d 03-10 average 9.85 07 __ 19-25 Feb 1990 ____ 9.70 08 __ 21-27 Feb 1926 ____ 9.50 09 __ 20-26 Feb 2021 ____ 9.46 10 __ 06-12 Feb 1903 ____ 9.33 11 __ 08-14 Feb 1899 ____ 9.29 12 __ 16-22 Feb 2023 ____ 9.26 13 __ 17-23 Feb 2017 ____ 9.17 14__ 04-10 Feb 1933 ____ 9.14 15 __ 06-12 Feb 1939 ____ 9.04 16 __ 20-26 Feb 1897 ____ 9.01 17 __ 23-29 Feb 2012 ____ 9.00 18 __ 07-13 Feb 1831 ____ 8.99 19 __ 07-13 Feb 1918 ____ 8.97 20 __ 21-27 Feb 1953 ____ 8.86 21 __ 09-15 Feb 1961 ____ 8.84 22t__ 05-11 Feb 1779 ____ 8.79 22t__ 22-28 Feb 1959 ____ 8.79 24 __ 20-26 Feb 1794 ____ 8.76 25 __ 23-29 Feb 1976 ____ 8.64 26 __ 06-12 Feb 1856 ____ 8.61 27 __ 23-29 Feb 1912 ____ 8.60 (rises to 8.91 for 25 Feb to 2 Mar) 28 __ 12-18 Feb 1779 ____8.58 29 __ 20-26 Feb 2007 ____ 8.53 30 __ 04-10 Feb 1990 ____ 8.51 xx __ 25 Feb - 3 Mar 1779 __ 8.63 (not ranked, see various examples below) ------------------- (also including 1-5 non-Feb days) ...

(xx __ 30 Jan - 5 Feb 2000 __ 8.57 __ average for 1-7 Feb was 8.07) notes: Feb 1872 ended with a 10.6 C on 29 Feb, and it stayed mild to 7 Mar. But weekly averages within Feb 1872 were all below 7.5. If the criterion was "any week with a day in Feb" then for the record 29 Feb to 6 Mar 1872 averages 9.30. Another technical qualifier this way was 26 Jan to 1 Feb 1846. The week of 25-31 Jan averaged 8.93 C. 1 Feb was 7.0 and dropped the seven-day average to 8.30. A higher average occurred later within Feb 1846 anyway. 1945 had two intervals separated by several days where seven non-consecutive days averaged 9.66 C but there were several quite cold days between these (17-20 and 26-28 average 9.66). 21-25 Feb 1945 average was only 5.8. 1877 6-14 Feb average 8.5 but no seven-day interval was any higher. 1935 14-20 Feb average 8.46. 1868 24 Feb to 4 Mar quite mild but similar to Feb 1945 two very mild spells did not fall into one seven day interval and the highest average for seven days in Feb was 8.5 C (22-28 Feb). 1867 15 to 21 Feb average was 8.4 C. 1876 16 to 22 Feb and 26 Feb to 3 Mar around 8.4 C. 1828 24 to 29 Feb 6d average over 9.0 but no seven day average in February over 8.6. 1794 12 to 25 Feb 14d average was 8.4 but no seven day average over 8.7 as days 7 and 8 of interval were near 5 C as were days outside the interval. 20-26 Feb averaged 8.76.

Just to confirm, 18 Feb 2024 set new record CET mean of 12.0 (broke 11.8 1945), leaving 1945 with high max of 15.2 (yesterday was 14.3). It also broke last year's record of 8.8 for high min with a reading of 9.7 C. (1911 was 9.0 in CET legacy but reduced below 1945 at 8.6 which lost that to 2023).

April was colder than February in 1903 (6.4 vs 7.1), 1809 (5.2 vs 5.7), 1790 (6.1 vs 6.6), 1739 (6.7 vs 6.8) and equal in 1837 (4.7) and 1713 (5.5). Four of the five years cited before 1903 (exception 1809) can be added to list for a colder march than Feb, as well as (going back from 1850) 1848, 1846, 1833, 1826, 1824, 1817, 1812, 1807, 1797, 1796, 1794, 1793, (1790), 1789, 1786, 1775, 1771, 1770, 1768, 1767, 1762, 1747, 1743, 1741, (1739), 1733, 1732, 1714, (1713), 1702, 1696, 1694, 1693, and 1674. There were also over a dozen cases of equal values (quite a few in the less precise era before 1720) including 1779 (7.9). Note a tendency for these older cases to occur in consecutive pairs. So the list extends the count above to 22 in 18th century and four in the truncated 17th century (but with less precise values and frequent cases equal, that four is likely closer to eight, so fairly similar in frequency).
