Overview
- From Monday, polar air drops temperatures nationwide, with rain turning to snow in higher hills and the Alps and widespread night frost developing.
- DWD describes an initial, limited winter episode, while models consistently point to more substantial snowfall confined to the Alps and parts of the Mittelgebirge.
- The strongest chance for broader wintry precipitation targets Wednesday and Thursday, when evaporative cooling could briefly lower the snowline to 200–400 meters in places.
- Some model runs, including GFS, suggest a risk of several centimeters of wet snow in parts of western Germany such as NRW, but forecasters stress low confidence and large regional differences.
- Coastal regions may see localized lake‑effect showers on Tuesday, and authorities advise winter tires, plant protection and close attention to updated DWD warnings due to possible glätte.
