“It’s not just a little spit,” promises Frédéric Glassey of Observations. There will be a nice little layer of snow in the coming days. Better: with the freezing temperatures which are also announced on Switzerland, it should accumulate well. “In theory, we expect more than 50 centimeters in the Alps, above 1500 meters above sea level,” said the meteorologist. The Jura, and even the Pre-Alps resorts can also hope for their share of white gold, since it should fall “between 20 and 30 centimeters of snow above 1000 meters above sea level, during the first episode of this disturbance which will keep us busy between Tuesday noon and Thursday evening ”.
It may even be possible to watch the snow fall in the plains on Wednesday, where we should expect a weather “typical of the sleet of March, with flakes that could whiten the soil, thunder and sleet “. But there, the snow will not stay “because the soils are hot, after this very mild winter,” notes Frédéric Glassey.
Giboulées Wednesday
Technically, this radical change in weather regime is explained by a collapse of the high pressure, which will give way to a series of depressions from Tuesday noon. The sky will be covered by the Jura, and the depression will reach the country during the afternoon. It will be followed by showers until the plains on Wednesday.
Obviously, this seems difficult to believe with the weather at the end of April felt on this Monday at the end of February, where temperatures were recorded at 19 degrees in Geneva and 16 degrees in Lausanne. This mild spring will however give way to an icy air, especially in the mountains. “In the plain, the thermometer will remain between 0 and 3 degrees, which is not very cold in absolute terms, but which represents a considerable difference compared to the 12 degrees measured on Monday, explains Frédéric Glassey. In the mountains, it will be more significant, with temperatures at 1,500 meters which will drop to -7 -8 Wednesday, when it is currently 10 degrees. “
Even if the weather situation changes, we are not witnessing any lasting change. Winter does not come on Wednesday. “And we are not on board for two weeks of cold. Rather, it is a winter episode, the return of visual winter. This episode will last about two days, with a little peak of warmth expected for this weekend, especially Saturday, before perhaps coming back to cold next week, but, at this stage, the trend is not still reliable ”, specifies Frédéric Glassey.
Whatever the trend: for skiers on vacation, as for those who are thinking of going back to the resort this weekend, these 50 centimeters announced will be more than enough for their happiness.
