High pressure is losing its strenght above the Alps. An Atlantic storm intensified the past few days and directed a frontal system into the Mediterranean basin. We are expecting significant snowfall in Southern Piedmont from Friday afternoon till Saturday. But expect freezing levels to rise significantly on Sunday. The most important weather models are in favor of an intensive storm cycle for the next week. Milder temperatures are expected with strong winds and significant snowfall for the Southern Alps at the end of next week. In this article:
The days with azure blue skies and clear nights will be soon behind us in the western Alps. The immense high pressure area is losing its strength, but it might take some time before the complete Alps may notice that. The vast majority of the Alps will stay dry with plenty of sunshine in Switzerland, Austria and large parts of northeast Italy. The wind will turn southwest causing the temperature to rise, especially on the northern side of the Alps where the Foehn will blow through to Saturday.
A frontal system has suddenly popped up on the charts and is now tracking into the Mediterranean. It is a rather small frontal system but this little engine is sucking colder air from the east into the Po valley and, in the meantime, pushing moisture from the south towards Northwest Italy. Snowfall will be the result once these air masses mix and encounter the eastern flanks of the Piedmont. We expect 10-40 cm of freshies for the Southern Piedmont and 5-15 cm for the rest of the Piedmont from Friday till Saturday.
Up to 20 cm of fresh snow fell already in Limone Piemonte last Sunday and there is more to expect for the upcoming 24 hours. Temperatures at 1500 meters will be warming during the weekend, but remain low enough to guarantee powder on Saturday.

The relatively stagnant pattern of the last week will come to an end with a new storm cycle on the weather charts. It looks like weather systems may come in from the west for the first time this season. This may cause a storm cycle with several storms moving in. Make sure you have your Gore Tex shell ready.
Stay stoked. Morris
