In the short term, an interesting contrast between MetO and Arpege; the former keeps today's/ tonight's rain stuck over Dorset (reports of flooding to be expected?) as it pivots there - Arpege moves it steadily up-channel.
Further ahead
16-dayer still showing cool weather for all of NW Europe for next two weeks and unlike yesterday the rain is back, week 1 all except Scotland, week 2 mostly in S England.
Jetstream - currently looping S of UK and converting to a steady and quite strong flow across France, just skirting S England, to Thu 20th when it folds into a new loop, again looping S of the UK, to Wed 26th after which the loop starts to break up and move E-wards.
GFS - LPs drifting across from the Atlantic, occasionally throwing in one which is deeper (Mon 17th 990 mb N Ireland, Sat 22nd 990mb S Ireland), the latter stalling over UK before a half-promise of warmth and HP from the SW Fri 28th.
GEFS - temps close to seasonal norm in N, a bit below in S, no real change even up to Fri 28th though as usual the last few days of the period show some variation (but not much)on either side. Rain mostly in a showery pattern throughout, wetter in SW at first, drier in Scotland later.
ECM - much like GFS, some weak ridges of HP between the sring of LPs
