Current situation and outlook
The cold of the last few days has gone and the thin, pre-Christmas snow cover is melting away, at least in the lowlands. The weather is currently dominated by a low over the British Isles. The Alpine region is on the front side of the depression in a westerly to south-westerly current that is steering mild air masses towards Central Europe. There is now enough snow at higher altitudes to ensure a white Christmas in many places despite the warmer temperatures. The comparatively cosmetic amounts of snow currently found in the foothills of the Alps, for example, will almost certainly not survive the coming days.
Today, Wednesday, will be cloudy in the west and snowfall will set in in the southern western Alps. In the east, it will first be clearer, then increasingly cloudy, with unproductive snowfall and possible black ice problems in the lowlands on Thursday night. On Thursday, the small disturbance will move eastwards during the course of the day and it will gradually become sunnier from the west.
