Today increasingly sunny and gradually foehn
After yesterday’s mostly cloudy day with rain in the lowlands and snow in the Alps! the sun came out again in many places today. However! it remained cloudy on the southern side of the Alps, where a moderate southerly! pressure system caused compact cloud cover. There was also some precipitation! until the morning. Particularly! from southern Ticino to Misox, 30 to 60 cm, locally even more than 70 cm! of new snow fell above 1800 meters within just over 24 hours. In San! Bernardino there was a 54 cm thick snow cover today.
It was also not very sunny in parts of the Central Plateau, because fog or deep high fog prevented any! sunshine in the morning. After the fog and high fog! disappeared, high clouds moved in, meaning that hardly any sunshine could be reported in the afternoon either.
The situation was different on the northern slopes of the Alps. During the course of the day, the foehn came up there, which had a drying effect. Incidentally, it reached as far as Vaduz, where the temperature rose to 19 degrees. In contrast to this year’s April, which has not been characterized by frequent foehn and southerly winds, these two weather elements are usually common in April, as will be shown in the sections below.

April – the actual foehn month
If you take a closer look at the frequency of the foehn saudi arabia phone number library over the course of the year, you will notice that the foehn clearly occurs most frequently in the Alpine valleys in April and May, although the warm downdraft from the south is a little more frequent in April than in May. The foehn is also relatively common in October and November, and in some valleys it also occurs frequently in the winter months. In summer, on the other hand, foehn events are rare.

In late spring and autumn, south and southwest exposures are relatively common
As is well known, foehn is essentially linked to south to southwest winds. Since these mainly occur in spring and autumn, it is not surprising that foehn and southerly winds are common on the southern side of the Alps at these times of year. It is not without reason that spring and autumn are considered the main rainy seasons on the southern side of the Alps, while winter is often quite dry.
