FAX - little change through to the weekend. LP somewhere between mid N Atlantic and SW Ireland pushing troughs and fronts along the Channel and then N-wards where they fizzle out as they come up against E-lies affecting N Britain under control of HP north of Iceland. Also noticeable is the number of fronts and thus a great deal of rain on the S side of the LP giving Iberia a soaking.
GFS Op - keeps the Atlantic LP slightly further north so winds are SE-ly rather than E-ly, but in neither case picking up really cold air e.g. from Ukraine. The current LP eventually fills Sun 8th only to be followed by another which makes more progress, and after a brief period with S-lies, settles 980mb N England Wed 11th and draws down cold air from large area of LP then over Scandinavia, However there's no co-ordination and after a confused period, normal service resumes and the chart for Thu 19th looks just like the one for today.
ECM - agrees with GFS to Wed 11th but the LP then settles in the Channel; colder air is restricted to N Britain and imports less for Scandi. But it too goes back to today's chart after Tue 17th
AIFS - London maxima 6-8C, slightly milder at each of the next tow weekends, rain on several days, wind between E at first and SW later. Edinburgh, similar temp profile to London but baseline 3-5C, rain frequent, winds mostly E-ly until later then SW/NW
GEFS - in the S, mean temp near norm well supported by ens members to Wed 11th when a spread develops (op below and control above) for a few days before converging again just below norm. Rain at any time, heaviest Fri 13th, as ever more in SW less in SE. In the N, cool at first then close to norm from Sat 7th and never good agreement from ens members(op & control very cold by Thu 19th). Only a little rain at first, then also more around Fri 13th, 30% chance of snow on low ground stations quoted, so almost certainly more on the hills.
