Overview
- A marked cold front will move from the west, arriving Wednesday night into Thursday, and replace late-summer warmth with much cooler maritime polar air across Germany.
- The Deutscher Wetterdienst (DWD) warns of thunderstorms, widespread heavy rain commonly around 20 l/m² and locally 25–50+ l/m² in orographic and staulagen, creating increased runoff and localized flood risk.
- Strong to stormy gusts are expected on the North Sea coast and in exposed high terrain, with typical gusts up to about 65 km/h and higher wind speeds possible on mountain peaks and coastal stretches.
- The Alpine snowline will fall to roughly 1,000–1,500 meters, and high staulagen may see measurable fresh snow (reportedly 10–25 cm locally), while lower hills could see graupel or briefly white roads in heavy showers.
- Practical risks include hazardous driving from heavy rain and aquaplaning, basement or runoff flooding in low-lying areas, and overnight valley frost by the coming weekend as a following high clears skies, so secure outdoor items, check drains and protect vulnerable plants.
