[size=4][font=arial,helvetica,sans-serif][b]Alps Overview[/b]


[size=4][font=arial,helvetica,sans-serif]After recent milder temperatures and spring snow conditions there has been a fall in temps over recent days, and with it some fresh snowfalls which have again created great snow conditions.

For much of the week, pressure over the Alps will be low, but with little variation in pressure, so light winds, and this should mean some hefty showers may develop more especially in the afternoon. Turning colder later in the week as winds turn round more to the North East.[/font][/size]

[b]Synoptic Summary[/b]

This weekend starts with High Pressure to the west of the UK running into Southern Greenland, with low pressure over much of Europe, the Alps has southerly winds but the Returning Polar Maritime air mass means 850Hpa temps around zero.

The trend for next week is for pressure to build very strongly over Greenland and right the way through Northern Europe, reaching 1060mb over Greenland, and 1040mb Svalbard to Norway by mid next week. Low pressure remains over much of North West mainland Europe and over the Alps, with 850HPa temps generally remaining around zero.

These generally cold conditions combined with low pressure gives the chance of further snow more especially over higher slopes.
