Intriguing battle not just between Atlantic and block but between ECM and GEM.

ECM looks like the risk of a proper snowfest into the SW Monday - Tuesday. Meanwhile GEM has fairly flat SWerlies, albeit still not exactly warm ones.

ECM has just as much chance materialsing as the GEM. ECM if i am correct got this spell correct as well? I know the GEM did well in the build up but ECM stays cold at the surface


GFS is still cold


Milder looking like it may appear mid month but potentially only back to the late february average.

Evening chaps.

Been over in the N/W regionals for a while. This spell is finally turning into a decent event here on the edge of Epping Forest. But, it was tortuous yesterday, snowing lightly all day but failing to settle before everything turned white overnight.

White stuff has been falling out of the sky since 0800 yesterday which is in and of itself remarkable.

The cold looks locked in for the foreseeable. Anything after Friday is FI.

ICON setting up a major battle on Saturday


The block holding firm to the east - pressure over Kent has increased from 1030mb to 1035mb over the previous 18 hours


http://modeles12.meteociel.fr/modeles/icon/runs/2021020812/iconeu-2-120-1.png?08-16


Heavy rain coming in to the SW


http://modeles12.meteociel.fr/modeles/icon/runs/2021020812/iconeu-42-120-1.png?08-16


Dew points are -12C to -15C in the NE of France and +10C on the Brest Peninsula


http://modeles12.meteociel.fr/modeles/icon/runs/2021020812/iconeu-18-120-1.png?08-16


How far east will that precipitation get before it stalls? The charts suggest the dew points rise above zero ahead of the rain hence why it is not showing as snow anywhere at T120. That may change if it pushes a little further east after T120 into colder air?

I agree ICON is showing a major battle. More chance of a big snow event. More chance of a resulting breakdown, but conversely more chance of the block being propped up further down the line and a push back from the east ...

Then slowly and inexorably the cold air pushes back westwards, the snow becomes lighter and eventually stops. Then the clouds clear just before dark and the temperatures plunge to the minus teens....


Sorry where were we?

The stronger the wind, the less time the air will spend over the sea. The English Channel isn't that wide, and the air over northern France should still be cold. So though there would probably be rain on the coast, hopefully there would be snow not too far inland. But a south-easterly would be better than a straight southerly.


Looking at the ICON snow lying charts at T+96 and T+120 as shown on Wetterzentrale, it looks as though between those two times there would be widespread snowfall apart from in the SW. 


And FWIW, the automated Met Office forecast for here for Saturday is snow with a maximum of 3C.

On the other hand, the WRF model at the same time stamp has more of a SE flow and colder DPs as a result

Ecm extended range latest 8th Feb Run


 


8th -15th Feb


High pressure between Scadi and Iceland


Low pressure trying to undercut from the N/W


Shallow low pressure Belarus


Likely outcome cold ese feed probably a limited attack from the S/west


How much energy gets under the block looks open to question


 


15 -22 Feb


Intense high pressure Scadi


Low pressure mid A


Looks like a Scadi victory cold continues cold s/e feed


Little energy appears to be getting under the block


 


22- 1 st March


Intense area of high pressure between Scadi and east Scotland


Slow East Feed BI


Very quiet Atlantic No attack in sight


 


1-8th March


High pressure continues just west off Scotland


Again looks very quiet with probable sharp frost and fog continues.


 


Cold maybe very cold February likely for BI if Ecm extended is to be believed
