Overview
- Temperatures tumbled after a Baltic low drove in polar air, with first snow in uplands from the Sauerland to the Swabian Alb and parts of Bavaria, and widespread overnight frost.
- DWD forecasts single‑digit highs with rain in lowlands and snow above roughly 400–600 meters, with 10–20 cm possible in the Alps and higher Mittelgebirge.
- Narrow, locally intense lake‑effect snow bands are expected over northern Germany on Tuesday as cold air crosses the North and Baltic Seas.
- County‑level warnings for snow, ice and gusty winds are in force in several regions, and motorists are advised to prepare for slippery commutes and use winter tyres.
- How far snow reaches the lowlands later in the week remains uncertain, with some models hinting at midweek flakes in western low elevations and a wintrier weekend, while DWD cautions against assuming widespread heavy snow.
