Only 24th is showing possible snow.


Slipping on to February and March - of course this is guesswork - it looks milder, but with snow indicated for 12th, 24th and 28th. I appreciate this a just a bit of fun and not to be taken as reliable - but if not true this is at least credible, based on the current winter. But as I stress, I am not a meteorologist and am just applying a vaguely scientific eye to easily-available information - so your superior take will always be fascinating.


TWO  Winter February forecast [01/12/2019] said: "Milder and wetter than average."


First half


Quite unsettled weather is forecast for much of the period with temperatures generally often close to average, but above average at times in the south. Rainfall levels probably slightly above the average with drier spells most frequent in the south and east.


Second half


The middle part of the month may bring a spell of colder weather with a risk of sleet and snow for a time in all regions. Milder and unsettled conditions are considered likely to return in the north and west. Quieter and drier spells are more likely in the south and east.


Keep it coming!

ECM 00z ensemble for London



A strong signal for a cooler/rather cold interlude next week before uncertainty creeps back.


The wind chart shows high pressure is likely to be in control for most.



Rainfallpattern as expected - a well-advertised wet spell in the next 2-3 days followed by very little at all thereafter.

Thanks Brian - how did I guess that the Op run was a cold outlier come the end of run!??


I wondered how to get the ensembles on TWO. So thanks.

It is not possible to say there will be no severe cold spells or snow in February. It is  almost possible to now say however that the first two months of winter will have been extremely mild and snow free. If we exclude March from "winter" then even a cold February, good as it would be, is unlikely to make it a memorable winter for me (As I have had several). Now if February and March were to be severely cold then........

’Severely cold’ is rare and unrealistic.


I’d be happy with three days of sub zero with sone snow lying around - but I’m getting old now 👍

It will be very interesting to see how this high pressure scenario plays out during the next couple of weeks. IME even "faux cold" scenarios don't stick around for long. More often than not there's too much of a breeze or muck comes in off the Atlantic over the top of the high.

Scandi high looks like it could form on the 12z GFS

Well the 12Z GFS certainly doesn't look mild, after Wednesday there are no double-figure maxima here, maxes generally about 5-7C falling to 3-4C at times, so slightly below average temps with an easterly drift for at least a week. On this run only of course...

Getting the high in in the first place has been a struggle so not focusing on what happens after too much. The GEFS look keen to collapse it or briefly retrogress but that’s a long way off. For now more seasonal weather is on the way and for many dryer weather which is good news.

Yet again the Operational is a cold outlier at end:

A mote of interest is better than none. ECM still wants to ride the block, but the pointers toward a more amplified pattern (and yes, that wouldn't be hard) persist.

ECM monthly from Hungarian met O has been updated: Week 4 (20th -26th Jan) has the SW of the UK being the coldest part of the country some -1 to -3c below average:


I anticipate due to frost and fog as it's below average across northern France as well.

As if by magic a two day toppler appears...its deep into FI but not seen snow and ice chart with as much fun suggests for a long time...not sure it will verify as there is a lot of uncertainty about the behaviour of the high next week, but I'll take a 2DT right now with its plunging cold fronts and snow shower bands.

Main difference this morning with the GFS op is it now shows mild conditions for much of next week. Spring-like at times with the high pressure.
