Overview
- Weather stations in parts of central and eastern Germany topped 20°C on Wednesday, including a new daily record of 21.4°C in Waldheim, Saxony, while many other areas stayed milder under fog and low cloud.
- High-pressure system Vianelde over Eastern Europe is driving the mild, sunny spell by steering subtropical air north and suppressing rain, with local föhn effects boosting temperatures in the Harz and Eifel.
- Meteorologists stress the warmth is an anomalous mild phase rather than a heatwave, noting maximums near 20–21°C do not meet common heatwave criteria.
- Forecasters expect a rapid pattern change from Friday: widespread low stratus and fog, fewer sunny breaks, and daytime highs easing to roughly 5–10°C through the weekend.
- The DWD has issued frost and dense fog warnings for parts of Bavaria overnight into Thursday, and medium-range outlooks for a mid-November Arctic plunge remain uncertain as newer ECMWF runs have weakened the cold signal.
