Overview
- The Deutscher Wetterdienst issued Friday warnings for heavy rain, thunderstorms and strong to storm‑force gusts with local gusts around 100 km/h and up to about 110 km/h in exposed high terrain.
- A concentrated rain band from northern Lower Saxony to Mecklenburg is expected to produce 20–35 liters per square metre in six hours, with isolated totals to 50–60 l/m² that can trigger urban flash flooding, aquaplaning and rapid ponding.
- Forecasters say the strong jet stream, wind shear and low VILJA are favouring organized convective storms, raising the risk of severe squalls, large hail and isolated rotating cells that could produce tornadoes in parts of the north‑east and east.
- Southern Germany will briefly see late‑summer weather with widespread sun and daytime highs around 29–33 °C before a Sunday‑wide easing brings calmer, sunnier conditions for much of the country.
- Model ensembles point to a pronounced mid‑week shift to cooler, wetter weather that could lower temperatures by up to about 20 °C compared with current highs and carries an uncertain signal for early Alpine snow in mid‑September.
