Overview
- Germany remains unusually mild this week with highs locally near 14 to 16°C in the west, while foggy southeastern valleys hover near or below freezing under a persistent inversion.
- The German Weather Service issued yellow-level alerts in 241 counties for light frost, dense fog and localized icing, with similar conditions expected again on Thursday morning.
- Multiple model suites point to a colder pattern developing after the holidays, potentially opening the door to continental air from the east toward year-end.
- Scenarios diverge sharply: some GFS runs simulate persistent frost, sub‑15°C nights and snowfall to low levels, whereas ECMWF solutions more often show only moderate cooling.
- Forecasters say a broad white Christmas remains unlikely at this stage, and any snow risk will depend on short‑term shifts in timing, moisture and the exact track of the cold.
