Well yes, as you have just stated above it requires a lot of preconditions to come together at -3C, so not really "easily", that's all I'm saying.

It's getting exciting. I tend to come here every year most days between September and March just to see what you guys are saying for snow and cold. 

I'm in Scotland, rural East Ayrshire, 200m above sea level. We had some cracking frosts in September and early October but not much of note since. 

I look forward to the reports of 9cm of snow in Hampshire on Friday but I'm not holding my breath. 

Interesting WAA going to the Western side of Greenland at T192 on the GFS.

Aye - we frequently hear the saying "complex area of Low Pressure" 

Its rare we say " a complex area of High Pressure", as usually theyre pretty well defined jelly fish like slabs on the maps..

But that area to the north of us is very much a big complex High pressure cell that has all sorts of complications going on

Maybe that WAA will kick it into touch 

GEM also going for a major snow event Friday. 

Arpege 12z seems much less interested.

Very different from GFS this time around 

Looks like snow for Brian across the Chiltern Hills, I might have a drive over there Saturday if that forecast holds. 

I would certainly bank that one please.

I like what the Control is trying to do

Aye, seemingly sticks with the block and slips things underneath it.  Bank

That is a thing of beauty. 

Plymouth showing a snow row of 17 around 5th.

5 days away.

OP on the high side 

very tricky Friday huge 850 scatter hints of Evap cooling across the set at 12z and 15z mostly all cold at the surface no 12 hits the jackpot  and a few others are  just about cold enough  imo

Yes there are 3 beautiful waves in P12. But most of the Ens spread is trending well below the long term line. Nice on the eve of Dec to contemplate the possibilities.

Very close

Yes - I wondered when we will see an upgrade in the cold and wintry potential in the shorter term soon? - Perhaps this is the start!?

GFS Op run is one of the milder options.

Looks pretty bland to me: https://www.wetterzentrale.de/en/topkarten.php?map=1&model=ecm&var=1&run=12&time=240&lid=OP&h=0&mv=0&tr=24#mapref

Huge Azores high, budging itself into Iberia, retreating Siberian high, nasty low spinning off the eastern seaboard... Am I missing something?

December 1st. (145 years ago tomorrow). 

A good ECM mean in the extended range with a pronounced -ve height anomaly over mainland Europe and the core of the trop PV well away from it's usual Greenland home.
