Yes a thing of beauty by the end . We can but hope.

shocked if it did happen countrywide snow and cold. At least it’s not a one off

I think significant blocking to our north is a good bet this December. We will need a bit of luck for it to be the perfect Greenland high like the GFS 6z though.

This isn't the 1st or 2nd time in recent days GFS has shown this 

The Op and the Control aren't that far apart 

Who would be a forecaster!  Some fantastic charts being shown consistently by GFS and it's bound to get excitement levels to fever pitch in the MOD...

Would be nice to see this stay in similar shape as we progress over the next 10 days so we get a proper count down.

4/1 for snow at Edinburgh/Glasgow airport on Christmas day

North thrown into the freezer....features running along the channel keeping south in the mild zone.....2010 the south coast missed the mild by a fag paper and snow went very soft haily at times ....

So quick summary of where we are for snow this week focusing on Thursday into Friday morning

EUR4 model (i still use it even just for fun) overnight Thurs-Friday

Snow to most of northern England, accumulations to Wales, Cennines and Cumbria

GFS overnight Thurs-Fri

Has snow from wales across the borders with significant snow to north east UK later

ICON overnight Thurs-Friday

Significant snowfall to the spine of Northern Britain

Arpege overnight Thurs-Friday

Doesnt like the idea of anything snowy - or heavy.  Pushes everything out to sea, and a bit of snow only to hills

CMC / GEM

Goes for an event later into Friday morning for Scotland

ECM

Goes for perhaps a bit more of an event for Northern England, then Scotland

The pink snow is back.

The final few charts of the GFS 06z run, to my eyes anyway, have more than a bit of a late November/December 2010 and mid-December 2009 to mid-January 2010 look about them, and for the avoidance of doubt this is not intended to sound like a ramp!

Obviously too far out to be taken in any way seriously at this time, but interesting to see nonetheless. One thing is for sure though which has already been mentioned by others, and that is at the moment at least, we seem to be in rather different synoptic territory compared to this time a year ago.

I dont think you are alone about this, but I think experience has taught us to be resrved.

Alot of chatter on Netweather about it too.

One run and all that, but the charts have been pointing towards a conclusion like this for a week or so, was only a matter of time before we saw some candy in the FI sequences... will be gone later 

That's the sort of set up that produces polar lows; always quite rare beasts but seemingly an endangered species in recent years.

But when they happen, they can be the most destructive of all winter weather events. Anyone want to use the time usefully between now and the 12s rolling out, here's a great link to an analysis of the Polar Lows of 23-25th December 1995

the high is better aligned already

Certainly a cold period coming up

It looks generally pretty cold for at least a couple of weeks. With the low fairly static stuck in between there are a lot of different possibilities I think, most better than usual for cold fans for the start of December.

Jetstream about 1000 miles south off its usual route

and yet, no real cold air

Yes, I think that is a pretty fair assessment. Whether it is anything more than pretty cold remains to be seen and I hate to use the word “potential” but it is probably appropriate this time. Coolish and Decemberish in terms of resulting weather if not synoptics, rather than mildish and forever autumn.

Think Harmonie model has Friday snow nailed.

On another note, does anyone know what are the best models for snow?

Yes it's the Harmonie model. 

Only a fool questions its veracity. 

It was wrong once, but it was so long ago that everybody has forgotten about it.

Underwhelming set of 12z though has to be said.
