Overview

• After a brief warm spike, a southwest‑to‑northeast band of showers and thunderstorms moves in from Wednesday into Thursday.
• Official alerts cite short‑period rainfall of 20–40 L/m² in a few hours with isolated higher amounts, creating a flash‑flood and drainage‑overload risk.
• Strong gusts up to 75–85 km/h and hail around 2 cm are possible, especially in Bavaria, Baden‑Württemberg, Rhineland‑Palatinate, Saarland, the Allgäu and Franconia.
• NRW and northern regions are expected to see a weaker impact with scattered storms, around 20 L/m² locally and gusts near 70 km/h, though forecasters stress track uncertainty.
• Forecasts indicate further unstable phases through the weekend, with renewed severe cells possible on Sunday and temperatures easing to roughly 18–24 °C.
