[b]Current Situation [/b]
There is High pressure centered (1028mb) over SE Europe, with pressure over 1020mb for most of mainland Europe. winds over western Europe are coming from a mild SW direction for much of the Alps and for Western parts of Europe including Southern Scandinavia. Colder air is restricted to the far north of Scandinavia where this a northerly flow and for Russia. The mild weather looks well set for much of mainland Europe, however Scandinavia is set to see a change, and this will be discussed in more detail below.

[b]Synoptic Progression[/b]
For most of Europe very little change over the next 24 hours, High pressure remains centred (1028mb) over SE Europe, winds remain from a mild S/SE direction. Fronts should remain to the west of the UK, although some rain cannot be ruled out in N and W areas. It should also be mostly dry over the Alps. Sunday sees almost an identical situation, a flabby High pressure covering most of Europe centred over SE parts (1026mb), this giving mostly dry and settled conditions over the UK and the Alps. The colder weather initially over Northern Scandinavia edging further south and then east over the weekend.

By Monday, the whole situation moves East, the High Pressure centre moves away into Asia, with Atlantic fronts finally making headway over the UK, the Alps should see lower pressure but ti should remain mostly dry. Winds for much of Europe of a southerly orientation so remaining mild. Tuesday sees a big area of High pressure build over Scandinavia, bringing mild weather with southerly winds on its western flank, but northerlies on its eastern flank so bitter air over Eastern Scandinavia and especially Russia. Further south over Europe very much in between weather patterns but remaining mild with winds from the West or South.

Wednesday sees the High pressure (1036mb) edge further east to be centred over Western Russia, so mild over Scandinavia but increasing bitter over Russia. Polar Maritime air starting to edge in the far NW parts of the UK, as a cold air pushes SE, but generally mild with ridging High pressure from the SW, with winds from deep to the SW for the rest of the UK and Northern Europe. The Alps and Southern Europe seeing Easterly winds on the northerly flank of Low Pressure centred over Northern Italy.
By Thursday, there is High Pressure over much of Central Europe, so mostly settled over the Alps, and remaining mild. Very unsettled for the UK and Scandinavia with some heavy rain, mild to start, over the UK but turning colder after the cold front passes through. Remaining very cold in the far east of Europe including Russia.
For Friday, the colder Polar Maritime air edging SE into Central Europe and the Alps, this gives the potential of snowfalls to quite low levels over the Alps for the first time in a while.
