Overview
- Official forecasts show a broad warm spell through midweek, with the southwest most likely to touch 17–18°C and nights staying largely above freezing.
- Alpine regions face localized hazards, including around 30 liters of rain per square meter in the Oberallgäu by Monday midday and stormy to severe gusts on peaks near 70–95 km/h, compounded by snowmelt runoff.
- A strong west-to-east flow and active jet stream are funneling mild maritime air into Germany, while a stable polar vortex is keeping true Arctic air bottled up to the north.
- Regional contrasts persist, with up to about 16°C in the southern Alpine foreland and cooler readings around 5–8°C in some eastern uplands, while Saxony-Anhalt is set for 13–14°C.
- Outlooks from the DWD and independent meteorologists indicate no marked nationwide cooldown before roughly December 18, and several forecasts suggest low odds of a widespread white Christmas, though late-month conditions remain uncertain.
