been hinted at could be very snowy or very wet

Crazy synoptics, but warmer than today along the south coast!

Jings, creevens!

I bet this run at this range sticks out like a sore thumb on the ensembles 

N. Hemisphere view @ 240 with strengthening Greenland HP - but looking at the uppers they don't look that good for snow?

I would not pay much attention to the detIls at that range as the overall trend is more important and it is increasingly strongly to cold. Nice to see the UKMO join the party too. Hopefully the ECM, GFSP and ensembles will also be encouraging.

Full reverse zonality by day 12 ! 

If the ukmo is outputting that then I'm on board on this being a decent event.  If ecm conforms then game on.

Remarkable but never really that cold for the south? - However, no easy quick way out of that massive HLB!!

Reverse zonality? Havne't heard that phrase before, Ian.

Great output this afternoon. To think as well that as recently as a few days ago, some of us were fretting over whether the cold spell would happen at all! Oh well.

It's just for fun at the moment but in this situation the far South especially would be at risk of milder air at times, as per the long range METO output. But potentially high reward snow wise where the boundary layer is.

Spookily enough, this winter is the 40th anniversary of the famous winter of discontent. The problem back then was the unions and not Brexit.

Looking at the models though, one wonders if the weather might be about to go into early 1979 mode?

Yep, that would do for me Ian, BTW almost 450 viewing the weather forum - new record?

Stunning GFS and cracking UKMO 

Don't know what this means but this ended up over the UK when we had beast from the east - the dark blue thickness line covering most of Scotland and N. England in FI?

(Get a) Grip (on yourself) 😂

Encouraging runs, though I note that the coldest air is  delayed to next Friday on some models.  Best thing this evening is the UKMO coming around and I will expect to see a decent set of 0zs tomorrow before raising my bar of expectation that I might see some frost or a flake of snow IMBY this winter.

Shortwaves developing over Norway and breaking a strong keen NEly into a slacker affair will be the main scupperings that may develop.  As is always the case the 'devil is in the detail' and it is important that only general assumptions should be made as regards the weather on the ground from 23rd onwards, ie colder, wetter with a risk of some wintriness.

A fascinating week of model watching awaits, though my expectations remain grounded, and for me, Friday 25th is the key date for possible arrival of some snow, for others it will be sooner.
