An Atlantic-dominated week but later a Scandi HP appears as an early Christmas present.
WX - the cold weather has stopped retreating and the temp situation is more or less static for the next two weeks; west of a N-S line dividing Germany temps are near average but to the east (which includes Scandinavia) it's much colder. Ultra-cold air is stuck somewhere near the Urals. Rain (probably) for Atlantic coasts from Britain S to Spain in both the next two weeks, continental Europe has some lighter pptn (snow?) and the patch over the Adriatic/Aegean in week 1 fades later.
GFS Op - Britain for the next 10 days is dominated by LP from the Atlantic but these make little eastward progress as a block begins to build over S Russia (990mb Severn estuary Mon 4th, 960mb Malin Thu 7th, 980mb Shetland Mon 11th, all including Britain as a whole in their circulation). The pattern begins to change Wed 13th as HP builds over the Alps (1025mb) linking with the Russian HP, first keeping Atlantic troughs further out to the west and then moving N to form an intense Scandi HP 1050mb from Shetland to S Norway Mon 18th with E-lies for Britain.
ECM - similar to GFS at first, though the final LP in the sequence does make it across to the Baltic Wed 13th, and though there is some suggestion of HP over the Alps then, it's not as evident as in GFS.
GEM like ECM
FAX keeps LPs at arm's length on the Atlantic, the LPs just about managing to push fronts across Britain on a SE-ly wind.
GEFS - temps rising irregularly to norm by Thu 7th and fairly good agreement on staying there to Sun 10th (a few colder members) and then increasing variation sets in either side of mean which stays near norm. (Op goes from being almost the mildest to almost the coldest 15-18th Dec some 10C either side of mean) Rain frequent in most places at most times, perhaps a little drier in the east later on.
