Overview
- DWD issues widespread yellow frost alerts, with nighttime lows commonly between −1 and −7°C and locally below −10°C in cold spots such as the Bavarian Forest and Harz.
- An inversion keeps higher terrain sunny and milder while many lowlands stay stuck in dense fog or high fog, creating ongoing ice risk on roads during early hours.
- Mountain hazards are elevated, with Bavaria’s avalanche service reporting moderate danger (level 2) above about 1,600 meters and the Erzgebirge facing gusts up to 85 km/h, locally near 95 km/h.
- Most regions remain dry with frequent sunshine through midweek, though fog persists in pockets such as the Upper Rhine and parts of Swabia.
- Some model runs hint at a late‑January moisture push that could produce localized snowfall of around 10–15 cm, but forecasters stress the scenario remains uncertain.
