Current situation and outlook
The Alps are under a large-scale bridge of high pressure, which will ensure mild, calm autumn weather. The high pressure forms a "bridge" over a low with a core between Spain and Morocco. Both the highs and the lows are fairly persistent in their positions and will only shift slightly over the next few days. Today, we will feel the influence of low pressure from the south a little more strongly: humid air will accumulate along the Alpine arc and in the north it will be slightly foehn-like with a high veil of cloud. There may also be Sahara dust here and there. The next few days will continue to be very mild and slightly foehn-like, with high fog clouding the sunny autumn weather in some regions.
Towards the weekend, there will be some movement in the weather. While the models have recently been showing quite substantial precipitation, the current runs no longer look particularly great. From today's perspective, Saturday will still be widely friendly, but Sunday will be more mixed. The most interesting prospects are for the southwest, where the genoa low is still playing a part. There is likely to be fresh snow at high elevations in the night to Sunday. A weak cold front will pass through in the north, but it will probably remain unproductive. All in all, it will be more of a scattered shot than a real onset of winter, as the cold air masses will land too far to the east.
High pressure is expected to gradually return at the beginning of next week. The outlook in the forecast is dry and sunny. The more or less brief winter interlude at the weekend should therefore be enjoyed as much as possible. Better keep your bikes and climbing gear handy!
