Overview
- DWD warnings Tuesday for wind, rain and mountain snow stayed in force, with the Brocken, the Harz and parts of the Allgäu reporting around 2 to 3 centimeters of fresh snow.
- Forecasters said Ascension Day on Thursday will be cool, cloudy and showery in many regions, with rain and some thunderstorms likely in North Rhine-Westphalia and highs mostly near 10 to 15 degrees.
- Nighttime cold brought widespread ground frost risks, and experts urged gardeners to delay planting tomatoes, peppers, basil and geraniums or to cover them during frosty nights.
- Major models, including ECMWF and NOAA guidance, now point to a possible jump to about 22 to 26 degrees around the Pentecost weekend, though meteorologists stress the outlook remains uncertain.
- The cold surge is linked to a low named Doreen that pulled polar air into Germany during the Eisheiligen period of May 11 to 15, leading to short-lived snow from roughly 700 to 1,000 meters and tricky mountain travel such as on the Riedbergpass.
