WX temps with respect to norm not altering much or W Europe - mostly a little above except for Spain which is below. Changes in week 2 include the shrinking of freezing conditions to affect only N Norway and Iceland, and a noticeable warming up around the Black Sea and E Mediterranean. Focus for rain in week 1 is N Atlantic, Spain and N Mediterranean; for week 2 Ireland, France and to a lesser extent the Balkans; becoming very dry to the east of the Urals.
GFS Op 00z - current HP withdrawing, one centre to Baltic, another to Greece, while on Sat 22nd a trough Iceland- Britain-Spain is in place. This forms a centre over France drifting slowly E-ward so by Wed 26th a blink-and-you've-missed-it ridge of HP passes over Britain before the next trough extends from Iceland and settles 975mb Irish Sea Sat 29th. This slowly fills and moves NE-wards only to be replaced by another 980mb NE England Tue 1st, and then something shallower in the N Sea Fri 4th. This model looks to be much wetter for Britain than for France contrary to WX above.
ECM - From Wed 26th the HP is more persistent lasting to Fri 28th, while the following trough skirts the north of Scotland to arrive off E Scotland Sun 30th, the chart then looking much like GFS for the 31st, but achieving this without deep LPs passing across Britain.
GEM - more like ECM, the Hp lasting a day or two after 26th but the subsequent LP runs S-wards across Britain instead of skirting round the coast, moving from 995mb Clyde Sat 29th to 1000mb Wight Sun 30th
GEFS - very mild now, drifting downwards, passing through norm Wed 26th and maybe a little cooler after that. Quite good ens agreement throughout, Rain likely around Sun 23rd and Fri 28th, the latter mainly in the S & W, bits and pieces at other times, but always rather dry in the far east.
