Overview
- The German Weather Service has active warnings for Wednesday evening into Thursday morning for parts of North Rhine‑Westphalia, Hesse, Bavaria, Saxony and Thuringia with forecasts of heavy showers, hail and storm gusts.
- Local authorities and forecasts cite specific hazards including gusts up to about 85 km/h and short‑term rainfall rates of roughly 15 l/m² per hour, with 20–35 l/m² possible in six hours in some warned districts.
- A pronounced air‑mass boundary is producing a sharp north–south temperature split, with many northern areas near 20 °C while parts of the southwest still reach about 30–32 °C.
- Satellite imagery and DWD analysis show rapidly developing deep convective cells in the south and west that can organize into slow‑moving clusters and deliver very high local rain totals.
- Forecast uncertainty is high because model runs diverge: Germany’s high‑resolution ICON model shows some runs with week totals above 100 l/m² in places while ECMWF projects much lower amounts, so residents should monitor DWD warnings for location‑specific updates and impacts such as flash flooding and travel disruption.
