WX summary temps - any heat wave deferred for a week, while the Atlantic holds sway. In week 2, a push of warm air from Spain NE-wards across France, and on to Sweden, catching England as it goes. The cold pool over C Europe also gets displaced further E-wards. Rainfall pattern matches this, mostly in week 1 from Scotland across to Baltic (Oban was mentioned on BBC last night as due to get 100mm in the next three days), week 2 splits to NW Scotland separated by dry area from fragments over E Russia. But a couple of wet 'blobs' over N France/S England hint at some local thunderstorms.
Jet - current streak across Scotland breaking up into loops by the weekend and these generally N of Britain; it's back again around Sun 22nd but weaker.
GFS Op - LP currently to NW moving across N of Scotland with some deepening at times until it drops into Sweden Sat 14th with pressure rise over Britain 1025mb E Coast Sun 15th and steady flow of air from well S or SW over the following week while pressure remains high (flies in ointment - LP still close to NW Scotland and what looks like a small thundery LP Sat 21st in the Channel) . The Hp at end of run Wed 25th has declined to a narrow ridge N Ireland - Alps, with SE-lies and LP sitting off to the SW on one side and NW-lies down the N Sea on the other.
GEFS - in the S temps near norm to Sun 15th after which a warm/v warm week (op & control lower temps than most runs). Back to norm Wed 25th but lots of variation in ens members by then. Little rain until a cluster from Sun 22nd. Temp profiles similar in N (a little cooler to Sun 15th). Rain profile for the NE as in the S but a lot of rain in week 1 for the NW.
ECM synoptics much like GFS, though perhaps LP a bit closer to W Ireland from Sun 15th. (only 12z runs from yesterday available after that date at time of posting) EDIT re-visited now today's 0z available and LP definitely closer, also close to NW Scotland

"Ground covered with snow this morning, having a great deal of snow in the night. This morning was fair but the air very cold" and "Very cold and very damp. Water overflows the ditches all round us ... Land springs about us were scarcely ever known to be so full as at present." Parson Woodforde's Diary, 13th and 17th March 1795, Norfolk
