Further snowfall is also likely in many places for the next few days, before things shouled settled down agin around midweek, and it slowly turning midler from the west.

[b]Synoptic Pattern[/b]

Currently the main players in the synoptic pattern is the Azores High which as so often this winter is displaced further north and east than normal (1035-1040mb), centered to the west of Northern Spain, but influencing conditions far further north including the UK with a WNW flow of winds. The Russian high remains in play around 1050mb. There is low Pressure from the south of Greenland, through Iceland and into Eastern Europe. The Polar Vortex is situated further west than has been the case so far this winter, allowing slightly higher pressure in the Greenland area.

Not much synoptic change by tomorrow, pressure though slightly building over Greenland to 1035mb, a NW flow over the UK bringing cool conditions to most areas, quite mild over most of NW Europe including the Alps, generally colder in Eastern areas and over Scandinavia .

Low Pressure again for Scandinavia and N and Eastern Europe, the UK on the dividing line with the more settled and milder conditions for the South West, colder for the NE you go in the UK, which largely is the same dividing line as is the case across Europe .

Monday sees the pattern move slightly further East, the Azores High ridging NE and starting to make things more settled again for the UK, but again with low pressure for much of Scandinavia and North Eastern Europe, and cool or cold here. Cool for the UK and NW Europe, rather mild over much of Southern Europe.
[attachment=127759:20 Jan +72.JPG]

High Pressure over Russia starting to influence conditions more over Northern Scandinavia and looking cold here. High Pressure (0130mb0 remaining over Greenland, and the Azores high feeding in milder SW winds over the UK ahead of a Low Pressure in the Atlantic looking to push over the UK. Mild again over Southern Europe, but cold over much of Central and Northern Europe including much of the Alps.

The low pressure slowly moves east by Wednesday with the High Pressure to the NE starting to act as a blocking high. Remaining mild and unsettled over the NW and North Western Europe, remaining rather cold over much of Eastern Europe, with the east of the Alps, much colder than the western half.

[attachment=127763:20 Jan +120.JPG]

Quite a lot of uncertainty towards the weekend, with the low pressure attempting to push east, and High Pressure (Siberian High) attempting to push in from the North East. So looking cold and settled for much of Central and Eastern Europe, cool to mild over Western Europe.
