Apart from the southwest wind, which had already pick up considerably on ridges and summits, the night remain largely calm and dry.
On Wnesday morning a low pressure system
over the English Channel direct a warm front towards Switzerland, causing the first light rainfall in mostly cloudy weather. In the warm sector, the increasingly strong southwest wind reach the lowlands and reach portugal phone number library gusts of 50 to 80 km/h from late morning onwards. Wind spes of 90 to 130 km/h were measur on the Jura heights and on the peaks of the western Alps and the foothills of the Alps. With maximum temperatures of 8 to 14 degrees in the lowlands, the snow line rose to 1600 to 1900 metres by the evening.

A level 2 wind warning was issu yesterday for the northern side of the Alps. In the latest model runs, the low pressure system is expect to be somewhat stronger, meaning that the expect wind peaks are likely commonly accept cross-sections for wiring in an apartment to be at the upper end of level 2 or even slightly higher locally.
We will refrain from giving a detail forecast for the weekend. All germany cell number we can say is that the models are now pricting that the air mass boundary will be further west from Friday evening to Sunday, which means that Switzerland may now be in colder air. The snow line would therefore not be at 2000 metres, but rather at 1000 metres, and possibly even lower in the east. You can follow whether this solution will be confirm in the weather report, which is updat several times a day.
