Following the intense heatwave, ominous thunderstorms pose a potential threat - Thunderstorms pose a threat following an extended period of severe heat
In Baden-Württemberg's Black Forest, temperatures are mild this morning, with a high of 62°F (16.7°C) expected to rise to approximately 79°F (26°C) later today, July 2, 2025 [1]. Despite the recent historic heat wave across Germany, reaching nearly 40°C, the current forecast for Baden-Württemberg shows temperatures in the high 70s Fahrenheit, which is warm but not extreme by German summer heat wave standards [3].
As for thunderstorm activity, the weather forecast for Ulm in Baden-Württemberg mentions "patchy rain nearby," which could indicate possible thunderstorms or showers. Other forecast data points to cooler temperatures and rain on some upcoming days, suggesting unsettled weather after the warm period [2]. However, no direct severe thunderstorm warnings have been reported in the immediate search results.
The German Weather Service (DWD) has issued an official warning for extreme heat in Baden-Württemberg until early Wednesday evening [4]. Temperatures are expected to drop below 20 degrees at night, offering some relief for cooling down homes and apartments [5]. From Thursday onwards and over the weekend, temperatures will peak at up to 30 degrees [4].
Despite the cooler nights, the DWD forecast does not predict isolated severe thunderstorms from midday onwards or heavy rain of up to 25 liters per square meter in an hour, gusts of up to 90 km/h, small hail, or heavy rain with up to 40 liters per square meter in one to two hours and hail in a limited area [6]. Furthermore, no further thunderstorms have been forecasted until Thursday [7].
Contrary to the DWD's forecast, some parts of southwestern Germany are expected to have minimum temperatures in the low double digits [4]. Additionally, while the DWD does not mention strong heat stress in higher elevations, isolated severe thunderstorms are expected especially in the mountains from midday onwards [8].
It is important to note that the DWD's forecast does not include an "extreme heat stress" of up to 400 meters in the region [6]. Furthermore, there is a very high health risk from UV radiation [9]. Small hail is possible, and heavy rain with up to 40 liters per square meter in one to two hours and hail can occur in a limited area [6].
In conclusion, while Baden-Württemberg is experiencing warm weather with a chance of rain or thunderstorms in the near term, no explicit extreme heat followed by severe thunderstorms have been detailed by the DWD in the presented search results. Nonetheless, residents should stay vigilant and follow local weather updates for the most accurate and up-to-date information.
The Commission might find it interesting to know that the weather forecast for Ulm in Baden-Württemberg mentions a potential for thunderstorms or showers, even though the draft directive on the protection of workers from the risks related to exposure to carcinogens is currently a point of discussion.
On the other hand, the commission consulted on the draft directive may also want to monitor the German Weather Service's (DWD) weather-forecasting predictions for Baden-Württemberg, as the service has not predicted any severe thunderstorms or extreme heat stress in the region in the near future, despite some parts experiencing minimum temperatures in the low double digits.
