Overview
- DWD expects an unusually mild spell Wednesday–Thursday (12–13 November), with highs near 20 °C in the Rhine Valley and along the Alpine foothills.
- A strong southwesterly flow is set to transport subtropical, at times Sahara‑dust‑laden air into Central Europe, lifting mid‑level temperatures roughly 10–12 °C above normal.
- Persistent fog and low stratus hold in many basins and river valleys early in the week, leaving some areas grey and cooler despite the broader warmup.
- From Friday into the weekend (14–16 November), ECMWF projects a swift ~20 °C drop near 1,500 m and a snow chance in the Mittelgebirge, with limited lowland risk if the stronger scenario verifies.
- GFS and regional outlooks also show a turn to colder, wetter conditions but generally less severe than ECMWF, so forecasters recommend monitoring DWD updates through Friday–Saturday.
