Overview
- Germany logged unprecedented December nights, including 12.0°C in Bremen (warmest since 1890) and 12.6°C in Dresden (since 1934).
- Updated model guidance lifts December anomalies to roughly 3–4°C above the 1991–2020 average, with little signal for a lasting cold spell before the third or fourth Advent.
- Operational forecasts from DWD and private services indicate lowland snow remains unlikely for Christmas, with only high Alpine areas retaining cover.
- Despite the general mildness, DWD issued level‑1 advisories for frost and dense fog in parts of Bavaria, and a brief weekend cool-down could bring localized night frost.
- The setup reflects a blocked pattern channeling mild Atlantic air into central Europe while severe cold and snow affect the northeastern United States and eastern Canada.
