Jetstream coming and going in short bursts across the UK for a week or so, but a more definite and stronger trend across or close to S of UK from Fri 24th for the week thereafter. That promises a continued unsettled spell, damp and cool from the Atlantic
GFS has won the immediate battle with ECM to be the form horse with HP reaching towards the UK but not quite enough to stop W/NW influence. This pattern persists to about Fri 24th with some promising days mixed with collapses. Then a general drop in pressure with LP established over UK by Tue 28th, pushing the ridge of HP south so that France gets the sort of weak HP that we' currently have
GEFS A little warmth around Sat 18th, but after that fairly good agreement on temps a little below seasonal norm throughout. Not much rain, and that mostly later on (after Mon 27th) and towards the N.
ECM has similar pattern to GFS but with pressure somewhat higher and thus better chances for good weather in the south
FAX and BBC have a trailing front which could spoil any HP by importing cloud from the Atlantic rather unpredictably.
