There was again some snow at the start of the week, but milder temperatures over recent days has led to a thaw and the best conditions over the higher slopes. However conditions are set to improve over the weekend with snow and colder temperatures pushing in from the North West. this week is set to be generally cold and turning very cold by the mid part of next week.

[font=Arial","sans-serif]There is a deep area of low pressure (960mb) centred over North America, and covering the North Atlantic. Further south the Azores High has ridged north over the southern Atlantic, and has starting to ridge just west over the UK. Low pressure also for much of Europe, running down from Scandinavia, Eastern Europe and an area to the SE of the Alps. A cold northerly wind over the UK and over much of Scandinavia, cool over much of Northern mainland Europe including much of the Alps. Mild over SE parts of Europe.[/font]

[font=Arial","sans-serif]Remaining rather unsettled over much of the North Atlantic with low pressure dominating. The Azores High has ridged further North East, with West to North west winds over the Atlantic and over the UK, where there is a mild flow. Remaining cold and unsettled over Scandinavia, cold over much of the Alps with a NE winds and the eastern edge of the Azores High.[/font][font=Calibri , sans-serif","serif] [/font]

Not that much change in the general pattern with low pressure over the North Atlantic and into Scandinavia. However further south west the Azores High ridges to the North West giving a NW feed over the Atlantic and into the UK and the Alps, feeding in a Polar Maritime airflow, cool to start of the UK and the Alps, turning colder in the UK later.

[font=Calibri , sans-serif","serif]A surface High develops over Greenland and with the Azores High ridging north gives a temporary block over the Atlantic. There is low pressure over North America and also over much of Europe, this will give a cold NW flow over the UK, with the potential of wintry or snow showers over windward coasts, this airflow moderated by the time it reaches the Alps, but still cool here. [/font]

[font=Calibri , sans-serif","serif]Wednesday sees the whole pattern edge further east, a cold northerly flow still over the UK, with still the potential for wintry or snow showers over the UK [/font][font=Calibri , sans-serif","serif][font=Calibri , sans-serif","serif] over windward coasts[/font]. The cold air is likely to have pushed further south into Europe and into the Alps with low pressure to the east. [/font]Low pressure still over America, with the Azores High starting to ridge closer to the UK from the south west.

A little bit of uncertainty towards the weekend, but the general theme is for the Azores high ridging closer to the UK, and introducing a little but less cold or maybe even mild air over the UK. Looking to remain unsettled over Europe and still looking cold over the Alps with a wind direction probably from a general northerly direction.
