    Would guess we will finish 5.3 or 5.4 before corrections but those could be fairly large, so anywhere from 4.9 to 5.2 seems most likely and see my earlier post for a summary of who said what in that general vicinity (not many went that high for CET). EWP looks to be settling in around 80 mm. The southeast has probably been considerably drier than that average. 

    The change in regime must seem even more dramatic in Germany, where I notice some readings today of 20 C, in areas that had -15 overnight lows in the cold spell, as well as 10-20 cm snow cover (I presume that's all gone). 

    The same thing has happened in Texas which had winter storm conditions a week ago and yesterday highs in the mid 20s (above normal but not record highs). Where I live it's a much more subtle change, we never got all that cold with a few days around -15 (not unusual for here) and now it's in the 5-10 C range with our deep mountain snow pack slowly shrinking away more from sublimation than melting although there's a bit of runoff evident on hilly streets around us. We had 70 cms of snow at peak depth in late January and that's more like 40 cms as of today, it looks the same outside but when you look more carefully the snow depths are definitely reduced. 

    We have quite a range in different climate zones around this mountan-valley complex, down in the Columbia valley the snow pack is only 10-20 cms, up on the alpine ski slopes it is closer to 2 metres. 

    Yes I think we narrowly missed out on another notable February warm spell in the UK with the warmer air mostly going into Central Europe. The models initially showed the warmer air heading towards the UK and we ended up with just mild to very mild air.

    Looks like Germany has had a spell similar to what we experienced in February 2019.

    No daily record, just 11.1C (0.3C shy). 

    Looks like a finish of 5.3C (5.33C) is most likely before corrections.

    This got me thinking, what is the record month for the difference between the lowest max and highest min?  Has this month got it?

    The range this month is 41.2c (-23.0 to 18.4).

    I don't recall December 1995 having maximum above 14.2c to get it (the difference to -27.2).  Jan 1982 i don't know about and I'm sure February 1895 didn't get that mild.

    I don't think the summer months would hold the record, but I could be wrong.

    This month certainly close if not the new record holder.

    Hope this is OK in this thread!

    I think a March might be the month to hold the record. 1958 I think brought very low minima below -20 degrees and warm maxima possibly. Jan 03 also brought abnormal high in Highlands as well as a low -18 degrees correct if wrong.

    For winter February 2021 appears to be a record.

    March 1965 is going to take some beating- incredible! Hard to imagine how a bigger range is possible in the UK.

    What about March 1958 which produced a low of -23 degrees, was there any warmth as well?

    Jan 1958 brought quite a range, -19 min and 16 degree max, not on a par with this month

    Awesome stats. So many in the past few years (August included as others have pointed out).

    I just think it's going to be very hard to beat March 1965 with that maximum of 25C. Look how far ahead it is of the nearest challengers as well.

    Can we expect the CET to remain stable now until the end of the month, as the next few days look fairly mild by day but with some chilly nights?

    The EWP tracker has reached 78 mm (24th) and appears to have added nothing on the 25th so with zero predicted on the GFS we are quite possibly at our final value. At least the preliminary value, the final value comes on the 5th when a table value is revealed and it can change slightly from the tracker. Anyway, I will wait until the 2nd when the tracker has reached the 28th to give a summary of EWP scoring for both February and the winter seasonal portion of the contest year. Only slight adjustments will be needed from the version shown a few days ago.

    Breached the 5 degree mark a bit quicker than I expected. Mean temps rest of the month look above average, though some colder nights, a finish of 5.5 degrees I expect, downward corrections, perhaps final mark 5.2. Comfortably above average, all that potential for a colder than average month swiped out quickly. To see a near 4 degree rise from mid month is quite something.

    Looks like this will be the final figure possibly get to 4.4C.

    At least it means I am not the only one that is several degrees out this month.  🤣🤣

    Indeed, those thoughts about this February potentially rivalling 1986 seem laughable now!  However, early in the month it was definitely feasible.

    February tuning out to be the warmest month of the winter.

    Who'd've thunk that back on the first weekend of the month!!!!

    February 1986 was actually cold right from the start - February 2021 wasn't, the first five days were actually on the mild side and the cold spell this month did not fully start until the 7th, so the chance of a sub zero monthly CET was out of the question this month right from the start.  Nontheless after the first week there was the chance that this month could have been cold overall, but was ruined by the cold abruptly fizzling out mid-month, similar in many ways to Februarys 2009 and 2012.

    Yes, it was never likely to be as cold as 1986 due to the milder start.  However, when the cold spell arrived it did look like it could 'lock in' and be a cold or very cold month.  This month has indeed been similar to February 2009 and 2012 in some ways, but unlike 2021, they too were cold from the start and ended up being close to average overall, rather than mild.
