If I am recalling correctly, I thought the end of November snow in 2010 was down to the jet performing some unusual acrobatics by picking up a load of cold air and firing it our direction, from the east.

You are correct, neither 2009 or 2010 cold spells were triggered by a SSW event. More so a good old fashioned enormous Greenland HP.

There isn’t a cat in hell’s chance I’m going to be suckered in by the vagaries of any model output or get embroiled in the swings and roundabouts and false dawns that is the funfair of model watching in winter.

Having reeled-off that string of idioms however, it is actually quite interesting 🧐

WX temps - the block of cold / freezing weather out to the east is still there and approaching Poland in week 2, throwing forward streamers over the Alps; but maybe not so intrusive as yesterday with most of W Europe including Britain slightly above norm in week 1and only cooling a little in week 2. Most of Europe, bar Spain and the W Mediterranean, dry in week 1, rain band developing down the N Sea and into France in week 2, also some in Italy and E Europe.

GFS Op - Mainly HP for the coming week, though a weak trough moves across the north tomorrow, Sunday, before the HP establishes W of Ireland. From Sun 17th LP takes over with centres N & S of Britain forming a trough over the country and by Wed moving W to become an LP 1000mb Holland. This continues to move away and by Mon 25th Britain is in a run of NW-lies between HP in Biscay and LP in Finland.

ECM - the breakdown of HP begins a day earlier, on Sat 16th, and takes the form of a dominant LP 975 mb Norway projecting N-lies across Britain , and  then including a secondary depression 985mb Clyde Tue 19th in the general cold flow (looks quite snowy for the Highlands)

GEM - More like ECM in timing and pressure distribution though the N-ly plunge is diverted to the N Sea and held E of Britain

GEFS - temps soon dropping to norm and mean then becoming a little colder from Sun 17th. Poor agreement between ens members; op  and control suggesting a milder spell than mean about Fri 15th, then colder about Tue 19th, this variation more marked in the north. Bits and pieces of rain here and there, becoming more widespread in more (but not all) runs from Tue 19th. Inverness snow row values in double figures from this date.

Well the GFS 6z is about as cold and snowy as a November run gets in the UK.

GEFS 06Z were a very mixed bunch. They should all be visible in this Tweet for 19/11. The op run was just about the coldest on this update.

If I was a betting man, I’d say northwesterly dominated from next weekend til December,  a brief dry spell before a Santa brings a hairdryer for everyone for much of December. 

I’d love to be wrong about that however.

EC is slightly more bullish on cooler snap than yesterday, but still attempts to bring in a more zonal flow by day15, if not earlier.

12z looking interesting....I remember 1988 a brief sharp northerly which brought 7 inches of snow to Dover( very local) late November....the rest of the winter you didn't need a sweater.....

I called this to a trusted friend in the pub last night….which usually ends up with the models backing down .  But currently ramping up something potentially special for the time of year .

Given what the last 15 years have been like the form horse has to be on the mild side. I think it might be statistically similar to the summer in that it was above average because of the cloudy nights - not because of long hot spells. I would go for, and obviously a guess not a forecast, is that there will be a lot of cold drab days like today making it often feel bleak and cold, but not very cold nights and few frosts and little snow south of the Midlands leading it to be above average for temps..

no mention of ‘hairdryers’ its the worst and induces irrational rage. Almost as much as ‘long fetch’
