In the Alps, it will also tend to be uncomfortable today, although not quite as windy as further north. A cold front attached to Sebastien will bring precipitation from the southwest, which will spread more or less across the entire Alpine region over the course of the day. The snow line will remain fairly high. In the west it will clear up again towards the afternoon/evening, in the east everything will happen with the usual time delay.
Thursday will remain fairly changeable with strong winds - now really from the west, slowly turning to the north - and repeated precipitation in the eastern Alps. In the west, it will snow or rain more persistently with a falling snow line. In the French and western Swiss north-western cones, there could well be significant amounts of fresh snow. However, there is little to nothing underneath...
On Friday, ex-Sebastien has finally moved far enough to the east and the Alps will benefit from a northerly flow on the back of the trough. Significantly colder air from the far north makes its way to us and, particularly in the western Alps, it snows quite a bit in the north. The amounts are not comparable to those of the recent snowfalls in the south, but still! Many ski resorts will be happy about the cold temperatures and will finally make snow on the still green valley runs for the start of the season. In the south, it will remain dry and relatively sunny with north föhn winds.
