Föhn

After around two weeks of fairly low temperatures, it will become milder again over the next few days. The cold air masses that have migrated to us from Arctic latitudes have moved eastwards and the high-altitude current is turning to westerly to south-westerly directions. After fresh snow in the north followed by considerable icy weather, the medium-term signs are now pointing to Föhn and südstau.

Every year, we and all the Christmas tourists are waiting in the wings, but the weather isn't really cooperating. The foggy areas in the foothills of the Alps are probably the most wintery at the moment. In the mountains, the sun is shining and temperatures are climbing into the double digits with the influence of föhn winds.

As my colleagues predicted last week, all that's left for me this week is the meteorological start of winter and tough, snow-unfriendly weather conditions. For the time being, we'll have to make do with what's left of the first snow of the season and what the snow cannons are still producing.

Dr. Ullrstein stands impatiently in his laboratory and attaches power cables to season 2025/26, which is laid out in front of him. At the end of October, his capacitors have enough energy for a first power surge and something twitches through the early season.

The cool, sunny spring weather will increasingly turn into summer temperatures with the onset of the Föhn wind. A late onset of winter is not in sight, but at least some precipitation is possible in the south after the long sunny spell.

Two PowderAlerts after a long drought! And at least in parts of the Alps, it's continuing to be reasonably wintry! The south in particular is benefiting from a relatively stationary area of low pressure that lies diagonally over Spain and France and is repeatedly producing südstau this week. In the north (east), the amounts remain lower and will not significantly improve the snow conditions, but will hopefully at least alleviate the acute risk of forest fires.

You're supposed to have good intentions in the new year and the oracle wants to be less serene and more enthusiastic in his old age. Ullr also takes heart and wants to give us more powder.

The heavens have given us plenty of presents for Christmas. It's still cool at the moment and there's still plenty of powder under the northern slopes of the Alps. But we are also thinking of all those on the southern slopes of the Alps who are unfortunately more likely to go for a walk in the foehn this year.

Before we head towards the Christmas snow, let's take a look at the large-scale pressure centers that rotate over the world's oceans and control our weather: The polar vortex currently has two distinct cold poles. One lies over eastern Siberia and the North Pacific. The other extends roughly from Newfoundland via Greenland to the Barents Sea and is responsible for a strong westerly current over the Atlantic, which has been bringing us "new weather" every few days for a while now.

As we all know, the WeatherBlog likes it when things are happening in the weather kitchen and suffers from acute boredom, which turns into restlessness if the weather stays the same for too long. We are therefore pleased to be able to announce: Something is happening! The next few days offer (almost) everything that Alpine weather can do.

The WeatherBlog is taking a summer break, unless there's another onset of winter with corresponding blog inspiration in between. Over the next few days, the south-west will be in full swing again - there would probably be a PowderAlert if our oracle wasn't already in summer mode.

Foehn storms in the north, metres of fresh snow at (very) high altitudes in the south, record temperatures followed by a sharp drop in temperature with a cold front: the last few days have been quite something. The weather has now calmed down somewhat. The next, much weaker southerly foehn is on the horizon for the weekend, probably with summer heat and no precipitation.
