A modest move in the direction of colder weather in the WX charts, from quite a restricted area for the time of year in week 1 (Iceland, N Scandinavia, N Russia) the cold air moves back SW-wards to Poland, Ukraine and mountainous areas in W Europe in week 2, but compensated for by (slightly) milder air moving N in the Atlantic - the Scottish Highlands lose their 'blue blob'. Rain/pptn continuing as for some time past to be concentrated on Atlantic coasts, including Britain away from the SE; becoming drier in the rest of W Europe.
GFS Op: 2022 finishes with LP generally to the N of Scotland and HP near Greece with SW-lies pushing across Britain into NW Europe (one LP gets rather close to W Scotland on Fri 30th). Then a very broad area of HP extends steadily N-wards with 1035 mb predicted for places as far apart as Greece, France and Norway on Wed 4th; S-lies for W Britain and N-lies for Russia. This remains in place for a week with minor variations before the final frame has it dropping back S-wards allowing zonal W-lies to re-establish.
ECM not dissimilar, but moves the area of HP N-wards toward the end of its run, centred 1045mb Baltic States, with the hint of a weakE/SE-ly setting up by Fri 6th.
GEFS shows mean temp often above norm esp near Fri 30th and for a longer spell near Fri 6th; near norm between these and later on. Rain centred around Sun 1st and again later Wed 11th. The N misses out on the earlier mild spell (locally some chances of snow in the Highlands); the E doesn't get the rain later on.
