WX temps dancing to and fro - yesterday's forecast advance of cold air into Europe stalls at Poland in week 1 and retreats a little in week 2, while a N-S seesaw develops, milder air moving N in Biscay and colder air S to the Caspian. (But remember this is based on GFS Op which is a bit of an outlier - see GEFS). Rain in week 1 on the Atlantic including Britain plus a large area in the eastern Med, the former moving N in week 2 and almost clearing Scotland, the latter shrinking.
GFS Op - current LP withdrawing to Atlantic and S-ly gales developing by Sat 26th. At this stage and following days HP over France and LP running SE from Iceland take turns to influence British weather, neither very strong; for the optimists, the HP wins Tue 29th and Fri 2nd, eventually becoming a major feature 1035 mb in the Channel Thu 8th.
ECM - on the other hand develops the HP Fri 2nd into a ridge 1050mb Finland to 1030 mb Ireland with E-lies for England and looking as if the HP will intensify over the Baltic. The BBC Weather for the Week ahead, never known for pushing the boat out, last night indicated a definite possibility(?) of colder E-lies in 10 days or so.
GEFS - bursts of rain until Tue 29th, but considerably less in NE, then drier. Temps near norm until then, after which mean is generally cool (2-3 C below norm), and would be lower if not dragged upwards by the Op and just 2 or 3 followers which are very mild.
GFSP follows the ECM output, positioning the ridge of HP so that winds are SE-lies rather than E-lies, and then moving it Fri 9th to W of Ireland with a strong N-ly down the far side of the N Sea
