SNOW, RAIN AND UNCERTAINTY
Coming days precipitation will fall as rain in the valleys, but also as snow above 1500 meters height. Up to 90 centimeters of fresh snow is locally possible until Sunday and the snow layer is regionally over 2 meters thick. Strong winds are possible in the higher areas and there is an avalanche risk. In the temperature forecast for next week there is large uncertainty, but some winter chances are there.
Today some precipitation will fall in the northwestern part of the Alps. The snow line will be around 1500-2000 meters height. In Switzerland and France up to 50 cm of snow is possible. With the combination of temperatures above zero, the risk of avalanches increase. Therefore, weather warnings are on force in Switzerland, Austria and France. With winds of 120 km/h on the mountain tops, it will not feel pleasant.
On Saturday, precipitation will spread over the Alps from west to east. Above 1000-1500 meters height snow is possible in all parts of the Alps. Regionally there will be some snow on Sunday, but not as much as previous days. On Friday and during the weekend, between 40 and 90 centimeters fresh snow could fall with the largest amount in southern Switzerland and around the Mont Blanc. The thickest snow layers can be found in South-Tyrol and in Wallis of more than 2 meters.
After the weekend it will probably be relatively mild. However, the uncertainty increases on the long-term. Cold and warm air are close and could both reach the Alps. In the warm air it could be around 10 degrees in the valleys, but in the cold air it will be around 0 degrees during the day and way colder in the mountains.
Low temperatures in Scandinavia
Extreme cold conditions can be found in Northern Europe. In Norway and Sweden we can find calm and dry weather with temperatures even below -15 degrees during the day and locally even -30 degrees in the nights. With a bit of luck, the cold air might shift to the south and surprise us with nice winter weather!
