I'll try and post something which is dispassionate and not too cherry-picked...
WX temp charts for week 1 hold the build-up of cold air (behind the 0C isotherm as a convenient marker) at E Poland before allowing to spread west to E France in week 2, not quite as far as yesterday. Something milder in Biscay, not quite reaching the Channel, and Britain still cold with sub-0C in hilly areas in N & W. Super-cold backup over Siberia has faded though a small patch remains over Norway. Pptn in week 1 on Atlantic with extension to France and Italy expands in week 2 to include Britain and Spain, and eastwards to Ukraine. A very good prospect for snow over hills in UK, some lower ground may be lucky but it's still a long way ahead.
GFS Op - HP over Scandinavia with ridge first to Britain then to Iceland hangs on until Mon 5th when pressure drops over Norway and Brittany to a situation Thu 8th 995mb Finland linked by trough to 1000mb Brittany with Britain in light NE-lies on the edge of the trough. The cold air drifts SW-wards and forms not so much a pool as a puddle over Britain, dispersed and cold rather than very cold, to Sun 11th. This model predicts a series of S-ly tracking LPs for the following week, notably 980mb N Spain with not-so-cold SE-lies Tue 13th, 985 mb E Anglia with much colder NE-lies Sun 18th.
BBC weather last night was showing a much more direct and strong cold N-ly for early next week, and on the radio this morning repeated by Stav Danaos as 'an Arctic N-ly early next week'. This is supported by FAX with the N/NE-lies in place by Tue 6th.
ECM follows GFS at first but by Thu 8th pressure has dropped over Britain (rather than over continental Europe) with more definitely cold air here and the fringe NE-lies pushed off to the Atlantic. The LP over Spain develops two days earlier, on Sun 11th, and instead of drifting E-wards and filling, moves NE-wards to 970mb NE England drawing some very cold air in from Scandinavia especially to NW Britain.
GEM is similar to GFS but emphasises the S-ly positioned lows (they don't track so much as fill) from Thu 8th, 980mb Biscay Fri 9th, 960mb Azores Sun 11th but with less cold SE-lies for much of this time; only on Mon 12th is there a drift of really cold air from the NE.
GEFS mean temps about 5C below norm for the next fortnight (almost up to norm for the S one day only Mon 5th) with good agreement between ens members, chance of pptn increasing through the period. Snow rows consistently 5-10 in the S from Wed 7th, around 10 in Midlands/NW England, 15-20 in Scotland and NE England, 20+ in the Highlands
