It has now been some time since there has been any significant widespread snow fall in the Alps, but that is about to change. The high pressure areas which dominated the Alps this week are starting to show signs of weakness and they will give way to a western current with depressions next week.

Colder air reaches the western Alpine region on Monday night. The influx of cold air is accompanied by heavy snow in the French Alps. It will give snow in the mountains above 1300m, then 1000m at the end of the night. This first disturbance will give 15 to 20 cm of snow at 1500m in the French Alps. The snow will soon extend to Switzerland and Austria in the late evening and early Tuesday morning. The snow level is initially somewhere around 1300 meters.

New disturbances are moving rapidly across the Alps from west to east. On Tuesday, much colder air rushes into the Alps from the west. As a result, the snowfall limit eventually drops to well below the 1000m. This second episode of snow fall can give between 20 and 25 cm in the ski stations in the French-Swiss border region at around 1000m.

On Wednesday, the weather will still remain very unstable with new snowfall expected around 1000m. This new episode should give 5 to 10 cm of additional snow to 1200m.

The most snow is clearly destined for the French Alps next week. By the end of the week locally there will be in excess of 110cm. A lot of snow is expected in ski reosrts between the Mont Blanc region and Zermatt. Paradiski and Val Thorens may welcome up to 120cm at places.

In Switzerland we expect between 70 cm in the border region with France, up to 50 cm in Berner Oberland. In Austria, most snow falls clearly in the west. A thick fresh cover of 40 cm is very likely.

For Tirol and Salzburgerland, the expectation with quantities of between 20 and 35 cm is slightly more limited. On the south side, most snow falls clearly in the western corner. Amounts are likely to be around 45cm. Further east towards the Dolomites we expect a welcome 15 cm of fresh snow.

New active disruptions are expected in the French Alps, especially Thursday and Saturday. The snow limit should rise higher in altitude and be around 1800m. These new snowfalls could give 30 to 50 cm of additional snow above 1800m.
