FAX - Atlantic storm winding up off N Ireland 958mb tomorrow, Sat (IoM Ferry company warning of possible cancellations) , only slowly moving past the W coast of Scotland before dispersing near Iceland Mon 13th; S England merely seeing showery troughs. New LP mid-Atlantic Tue 14th 980mb, not as stormy, but set up to push fronts across Britain as a whole.
GFS Op 0z - similar to FAX though the first LP gets into the Highlands on Sun 12th. The second LP stays further off and not as deep as it moves to Iceland, initiating a SW-ly flow (no doubt with an embedded trough or two) which fades as pressure rises from the south, 1030mb Ireland Sun 19th. This stays in the general area of Rockall to Sun 26th, pressure high over Scotland, E-lies through the Channel.
ECM - as GFS to start with but takes the HP Sun 19th further east, to the N Sea, with S-lies for Britain generally Mon 20th, before moving back west over Britain with the Channel E-lies less marked.
AIFS - London, maxima rising to 15-17C for the period Mon 13th to Wed 22nd before falling back, dry for the most part, chance of overnight frost Tue 14th, some trivial rain this weekend. Edinburgh, maxima also rising over the above period but only to 12-14C, rather more rain this weekend and also Thu16th, then dry.
GEFS, a mild pulse Sat 11th (weaker in the N), then mean temp quite well supported by ens members close to norm to Sun 26th (a little cooler at first, milder around Wed 15th). Many ens members showing rain at varying times, just a spot or two in the S, a little heavier in the N with the NE wet on Sat 11th, but the far NW as ever has both heavy and persistent rain
