Overview
- The Deutscher Wetterdienst issued wide warnings for severe thunderstorms, heavy rain, hail and the possibility of short-lived tornadoes before the main convective episode on Thursday.
- DWD confirmed a short-lived IF1 tornado in Gronau (Westfalen) and said other reported damage cases are still under investigation.
- Forecasters warned the strongest storm cells could produce orkanartige gusts locally around 120–129 km/h, short intense rain pulses of about 20–30 l/m², and hail up to roughly 2–3 cm.
- The most dangerous phase of the storms eased overnight into Friday with showers and isolated thunderstorms remaining possible and the DWD urging people to keep monitoring WarnWetter and to secure loose objects.
- The episode was less widespreadly severe than some forecasts had feared, likely because pre‑existing cloud layers limited instability, but officials note leafed trees and prior dry spells increase the hazard from falling branches.
