Jetstream still looking very unstable with the main flow throwing off loops before briefly resuming W-E; loops over Corsica Mon 12th devloping into braoader one over W Europe Wed 14th; S of Iceland Wed 15th; Madeira Mon 19th; Baltic Mon 26th. So the UK can experience the jet from almost any direction temporarily, though there is a brief straight strong NW-SE across Scotland Fri 23rd.
GFS - LP moving down N Sea Tue 13th to settle briefly over France; rather broad but weak area of HP over UK for rest of week before LP moves S over Ireland Sun 18th. New area of HP affecting all UK through to Tue 27th but tending to stand off to W so expect cool N-ly weather.
GEFS - Good agreement on consistently cool temps to Mon 19th (ca 5C below norm) after which maybe closer to norm but sudden onset of uncertainty then. Rain ca Tue 13th; dry-ish for a while, frequent instances of rain after Tue 20th but no agreement on detail.
ECM - similar to GFS to Thu 15th but area of HP less extensive with LP hanging around W/SW of Ireland. Then quite different as LP moves across UK Wed 21st by which time HP has disappeared.
Generally, don't trust any forecast much beyond midweek
