A high-pressure ridge has moved in from the Atlantic over the Alps. This is keeping low-pressure systems at bay and ensuring that we will remain clearly within the influence of polar cold air masses until the middle of the week. Sunshine will continue to dominate the skies above us from Monday to Wednesday. Harmless clouds may occasionally brush the edges of the country from the south, but they will hardly dampen the overall sunny impression. During the partly clear nights, the polar air that has flowed in will cool down even more. The days until Thursday will therefore start off bitterly cold, and it will remain frosty during the day despite the sunshine. There will be more movement in the weather from Thursday onwards. A windy and very changeable westerly flow is expected for the second half of the week. This will bring repeated precipitation. However, as the air is now coming to us more from the Atlantic, the snow line will also begin to fluctuate more strongly.
