Storm warning: Where thunderstorms are to be expected in the evening

Warm to hot in midsummer and not always only sun – this is how the forecast for the weather next week in Austria can be summarized. According to the Central Institute for Meteorology and Geodynamics (ZAMG), there is also a high risk of thunderstorms. This is especially true for Monday evening and then again on Friday from the west.

At the Monday high air pressure and subtropical warm air masses bring a lot of sunshine and summer temperatures. While in most parts of the country the sun shines most of the time from a largely cloudless sky, some cumulus clouds form over the Alpine peaks during the course of the day. The wind usually blows weakly, only moderately on the eastern edge of the Alps, temporarily even briskly, from directions around the southeast. In the morning, the temperature is between 14 degrees in higher Alpine valleys and 22 degrees in downtown Vienna, by the afternoon maximum values ​​between 26 degrees in the west and up to 35 degrees in the east are expected. In Upper Austria, peak values ​​of 34 degrees are expected.

Gusts, heavy rain and hail

In Upper Austria, the ZAMG expects “partly very strong thunderstorms” coming from Bavaria, which will come up from the west in the evening or in the first half of the night. “The storm and hail potential is quite high.” ZAMG issued a storm and thunderstorm warning from 7 p.m. to midnight. Wind peaks can reach up to 90 km/h throughout Upper Austria and even 100 km/h, especially in the central area. Hail and heavy rain are also possible. “Trees can break, roof tiles can come loose, scaffolding can fall over,” says the weather warning. Small-scale flooding and hail damage is also to be expected.
