Tropical hot days will end in thunderstorms
Prepare for summer-like heat and thunderstorm danger in the coming week. Temperatures could reach up to 37°C, marking the hottest days of the year so far. However, storms will quickly follow, moving from west to east across the country.
Tropical "Maschal" brought another summer-like day with minimal thunderstorm risk to the Alps today, Sunday. Monday will also start off very sunny. However, the next low-pressure system is already approaching from the west, intensifying the hot stream and bringing us the hottest days of the year so far at the beginning of the week, with peak values of up to 37°C.
At the same time, there's a notable difference from Sunday: it will become significantly more humid from the southwest. This will result in the first thunderstorms with storm danger in the south on Monday. The transition will then be a slower process from Tuesday to Thursday night, as the storm zone moves from west to east.
How extreme will the heat be in the coming days?
It will definitely be the hottest days of the year, with peak values of 36 or 37°C expected on Monday and Tuesday. The high humidity will make the temperatures feel even higher. Nighttime temperatures will also remain tropical, especially in cities, with values not dropping below 20°C.
When will the thunderstorm danger begin?
It will become increasingly dangerous from Monday, with Tuesday and Wednesday being the main storm days. The northeast will not have much to fear initially, as the focus will be in the west and south at first. The storm danger in the east is likely to increase later on Wednesday.
What can we expect on Monday?
Initially, there will be plenty of sunshine and few clouds. As the day progresses, thunderstorms with storm danger may develop over the southern and possibly southwestern mountains. The coast will remain pleasant at 20 to 25°C, while it will be hot elsewhere, with temperatures up to 35 or 36°C in the southwest.
Where will the storms strike on Tuesday?
After a widespread tropical night, it will often be sunny and dry at first. However, then thunderstorms will move from the northwest across large parts of the country to the south. The northeast and east will remain calm and sunny. It will become even hotter and more oppressive, with temperatures up to 37°C along the Rhine. However, it will be over 30°C in many other places, with temperatures around 25°C near Rügen and Usedom.
And on Wednesday?
The east will be pleasant at first, while the rest of the country will start to rumble again, either later in the day or from the night before. Then the storms will move east in the evening, bringing storm danger again! Before that, it will become hot again, with temperatures around 34°C, and 24 to 30°C in the west. However, it will remain humid overall.
Will it remain dangerous until the end of the week?
The storm danger will decrease on Thursday, and the storms will move east quickly. Only in the south could there still be some activity. In the north, individual showers may fall, otherwise, it will often be dry with some sunshine, with temperatures at 21°C on the North Sea and around 30°C at the Upper Rhine. On Friday, new showers will arrive from the northwest with strong winds. In the east and south, it will mostly remain friendly, with individual storms forming towards the Alps. The highest temperatures will be 20 to 25°C in the northwest, and 25 to 31°C elsewhere.
The weather forecast indicates that the hottest days of the year with temperatures up to 37°C are approaching, marking a significant rise in temperature. Due to the approaching low-pressure system, humidity levels will increase, leading to the first thunderstorms with storm danger in the south.
