Overview
- Temperatures remain unusually mild for December with widespread highs around 7 to 14 degrees, dropping to 2 to 5 degrees in persistent fog according to DWD.
- December 2025 is tracking among the warmest since records began in 1881 after back-to-back night records earlier this week and an upgraded NOAA outlook.
- Forecast guidance from DWD, ECMWF, GFS and others keeps a southwest flow locked in through the third Advent, leaving little prospect of widespread snow or a lasting cold spell.
- Short-lived regional cooling is expected over the weekend, with DWD frost and dense-fog alerts for parts of Bavaria and a localized risk of slick roads.
- The blocking pattern erodes natural snow cover and may favor windy or wetter episodes later, though any Christmas storm or colder turn remains model-dependent.
