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.

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.

The period of southern storms is over and this week we are dealing with slightly early April weather. A mix of sun and clouds and a few showers here and there characterize the picture. Winter might make a comeback over the weekend!

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.

Frank Techel is an avalanche forecaster and researcher at the SLF. He deals with the integration of models into operational avalanche forecasting and believes that there is great potential to improve avalanche warning when humans and machines work together. In the interview, he explains how "AI" supports the human SLF team in producing the bulletin and where the limits of the models lie.

Colleague Sebastian dedicated last week's WeatherBlog to the new PG weather, because of course it deserves such a dedication and because he didn't just want to "moan about the weather forecast". I, on the other hand, love to moan and have no inhibitions about making up for it this week for both of us!

The warm, slightly foehn-like Kaiser weather of the last few days has been replaced by overcast skies and even a few snowflakes here and there. Overall, however, the weather situation in the Alps still falls into the category of boring, dull weather.

Fresh snow, storms, high avalanche risk in places - winter was barely declared dead before it was back, at least for a few days. Thanks to the fresh snow of the last few days, the snow depth on the main Swiss ridge is approaching the average again, but without replenishment and with settling, it won't stay that way for long. If you can, you should enjoy the snow with due caution while winter is still within reach.

Apart from a short, unspectacular break today (Wednesday), there will be plenty of sunshine and little chance of fresh snow for the time being. It will become increasingly milder at higher altitudes over the next few days, while the cold air will linger in the valleys.

Cheers to the New Year! The Christmas period of high pressure is coming to an end and 2025 will bring a change in the weather - it's about time! A cold front will bring some variety and even a bit of precipitation from tomorrow. The outlook for the coming week is still very uncertain. Depending on the mood of the Azores High, the options range from mild westerly weather to an Atlantic block with an outbreak of cold air over Central Europe.

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.
