Overview
- The German Weather Service expanded light‑frost warnings on Tuesday into roughly 250 counties and cities, with lows locally near −3 C by Wednesday morning.
- Daytime weather turns sunnier and milder from midweek, with highs widely between 12 and 19 C and locally above 20 C in the southwest.
- Strong east winds persist on Black Forest peaks, where the DWD notes storm gusts are possible on the Feldberg.
- The cold nights follow a recent cold front that brought showers and mountain snow, with flakes reported in Bavaria above about 1,200 to 1,400 meters.
- Long‑range guidance from GFSv2 and ECMWF suggests a warmer May that could boost thunderstorm chances, an outlook forecasters flag after heavy rain in parts of the east.
