FWIW GEFS35 is still favouring colder conditions in Feb. Others may disagree but I think it has been performing well this winter.

From a rather cursory look it seems that now the GFS has opted for a less favourable (for us) pattern it has become rather more consistent with the overall picture. Detail obviously changes from run to run but not the major shifts we have been seeing.

GFS appears to be firming up on a very mild spell in the south and Midlands with, as predicted a few days ago, temperatures into the low double digits, possibly up to 13-14c in any sunshine. This was initially showing for one day, but is now showing 2-3 days. A growing sign of a significant warm up and no sign of winter.

LOL. That should skew the modelled temperatures for the next day or so when it is fed into the NWP!!!

Edit: I think you may say there are signs of the pitch beginning to lose its pace and bounce.

I notice the GFS esp Operational run in particular has always been the milder option in the FI range or from the 24th. Is this a trend setter? who knows?

As the last of this mornings snow now melts its time to start looking to the next event.


Image may contain: sky, tree, snow and outdoor, text that says "KEW WEATHER IMAGES"


Here in Folkestone I've witnessed 3 separate altitude brief snow events locally this winter (4th December, 8th January and 16th January).


At FI 120 hours these charts look tantalising.


Greenland High far enough east to prevent prolonged Tm incursions, deep low pressure advecting cold air south across the UK and an arctic high nosing into Svalbard acting as a conveyor to start ushering very cold very deep arctic air SW'wards. Check out historic cold events of the past and you'll notice many charts looking like this a week or two before.


This progressing pattern with secondary lows spiralling on ever southward tracks will bring cold air a good deal further south with time.

Out towards day 10 and both GFS versions want to put a high pressure centre over southern Portugal; ECM and GEM put it over Morocco. That's a difference of 500-600 miles, which whilst very little in global modellling terms is very significant in terms of whether there's room for LP systems to run to our south or not.

I paid a visit to Paddlesworth (187m asl) again at 9.30 when the snow had become a rain, sleet snow mix. By 10.15 it was 100% rain.

Cold cluster has entirely disappeared with the exception of a few briefly prolonging the cooler spell at the end of the next week.

After that it is pretty unanimous on a warm up, although how warm is open to question. Possibly a hint of a renewed colder incursion as we enter February.

But barring any short term surprises I think those of us in the south can safely put a fork in January. It’s done.

I’m not sure Rob even the GEFS ensemble suite has been very volatile over the last few runs

Decent snow this morning in Epping Forest, got out sledging with my boy. Got my snow fix from a very marginal set-up!

Be nice to get a proper easterly in before winter is out. Plenty of time yet!

Decent shift south on the 06z run this morning of colder 850's with a greater threat of snow for the southern half of UK later in the week and over next weekend. Hoping to see this trend continuing over coming runs.
Waste of time looking beyond day 8 as large variability from run to run shows.

Trying to see the positive here in the medium term ENS show a shift to slightly cooler 850's between 22nd and 25th:


00z ENS AVG:


23rd -4.9c


24th -2.1c


06z ENS AVG:


23rd -5.7c
