Overview
- Official DWD alerts cover roughly half the country, including a time‑bound black‑ice warning for parts of Lower Saxony and Bremen from 00:00 to 09:00 on November 20.
- Heaviest snowfall is concentrated in west‑facing mountain areas; the Hochschwarzwald can see 10–15 centimeters widely and locally around 20 centimeters, with stormy gusts on peaks.
- Snow or sleet is reaching lower elevations at times from the Harz to NRW and parts of the south, creating hazardous roads from fresh snow, slush and refreezing moisture.
- Daytime highs mostly hover near 0–6 °C, while nights turn widely frosty with typical lows around −2 to −8 °C and below −10 °C in higher terrain, bringing the first widespread frost even in lowlands of NRW and Hesse.
- Forecasts signal a further winter surge late Saturday into Sunday (22–23 November) that could extend snow and very low temperatures more broadly, though exact extent remains uncertain.
