Trends for the weekend
Weekend in Valais
The weekend of December 5-6 is expected to take place under low-pressure conditions. A short episode of föhn could still last part of the day on Saturday. Otherwise, clouds will prevail and produce some precipitation. The rain-snow limit is still poorly defined. It will probably oscillate between 600 and 1200 meters depending on sectors and times. On the other hand, more heavy snow is expected along the Italian border and in the Simplon region by dam from the south.
