FAX - still LP to the SW with fronts into the south losing their force as they come up against persistent SE-ly/E-lies over Scotland (a slight easing early next week, but back again by Wed 11th.
GFS Op - brings the new LP on Wed 11th in further N, positioned over Scotland 970mb Thu 12th and beginning to draw in cold air from Scandinavia which spreads down to Cornwall with N-ly gales by Fri 13th. A ridge of HP for the weekend, then a Greenland LP runs down to N Scotland 965mb Mon 16th and sticks around for the week with cold (but not deep cold) NW-ly polar maritime for the week following. A new ridge of HP for the weekend again, followed by strong S-lies as LP nears Ireland Mon 23rd. [Headline - winter 2026 lasts 2 days - at least away from N Scotland]
ECM - agrees with GFS though the cold plunge on Fri 13th is concentrated on the east coast (never gets to Cornwall). After the ridge of HP at the weekend, the next LP comes in from the W not NW , draws in some cold air for the N and looks like setting up a trough to the SW again (this to T+240, Tue 17th - I have to go and catch a train and ECM has only downloaded to 17th)
AIFS - London, maxima around 10C but with a dip to 3C just for next weekend, rain on most days, winds in the S except N-lies for the weekend. Edinburgh, similar but with lower maxima 6-7C , and a more gradual decrease to the colder weekend, frequent rain, winds E-ly for the week, N-ly for the weekend, then S-ly and finally W-ly.
GEFS - in the S, good agreement on temp above norm to Fri 13th and a two-day dip to 7C below norm; for the week following, mean near norm with a balance of ens members on either side. Never really dry but rain most likely around Thu 12th & Tue 17th, drier in the E with some chance of light snow at times. In the N, similar though mean only recovers to a degree or two below norm in the second week; as the norm is lower than in the S, a reasonable chance that pptn will fall as snow even at lowland stations.
