Overview
- The German weather service (DWD) issued warnings for renewed thunderstorms on Thursday with the greatest risk in the south where forecasts call for about 30 litres per square metre in an hour, hail near 3 cm and gusts up to 100 km/h.
- Northern and northwestern states face locally strong storms on Thursday with 15–30 l/m² rainfall rates and gusts of roughly 65–80 km/h that can still produce flash flooding and hail damage.
- Midweek storms in Baden-Württemberg already produced flooded cellars, fallen trees, traffic accidents and temporary outages affecting roughly 6,000 households, with emergency services reporting dozens of deployments around Lake Constance and Reutlingen.
- An airmass change is forecast to follow the storm period, bringing a marked cooldown over the coming weekend with many places dropping below 25°C after the heat subsides.
- Operational models continue to show a conditional chance of a fourth heatwave in late July to early August if a stable Omega pattern and Saharan air arrive, but that outcome remains dependent on those large‑scale patterns coming together.
