After a relatively mild spell, dominated by dry weather and high pressure, things turn colder and snowier over the Christmas period – this will be limited to resorts hugging the Italian border, however, as this snow is driven by a “Retour d’Est” system making its way across northern Italy.
A cold front will begin to push into the northern Alps on Christmas day, bringing moderate snow to resorts at higher elevations. Expect snowfall around 800m, with accumulations of 5-10cm across higher ground. Temperatures will dip to -4°C at 2,000m, making for crisp, wintry conditions. This will continue into Boxing Day with a further 15cm expected down.
Conditions will shift again as the weekend begins, with high pressure and fine, dry and bright conditions returning to the Alps. The freezing line will remain cold, hovering around 1,000m throughout.
