Overview
- Meteorological services say the last warm day is Wednesday and a kräftige Kaltfront will move in Wednesday night into Thursday, bringing widespread rain, showers and thunderstorms.
- The Deutscher Wetterdienst has issued warnings for locally heavy rainfall with rates up to about 30 l/m² in 12 hours in parts of the Schwarzwald and gusts near 70 km/h in warned areas.
- Colder Atlantic and polar air will push the snowline down to roughly 1,500–1,000 metres, with forecasts of measurable fresh snow in Alpine staulagen such as the Zugspitze and parts of the Allgäu.
- After the frontal passage a high pressure builds into the weekend, clearing skies and allowing strong night‑time cooling that could produce widespread frost with valley lows near −1 to −4°C.
- Practical impacts include possible localized flooding from heavy rain, travel disruptions from stormy winds and mountain snow, and advice from forecasters to protect plants and secure loose outdoor items.
