Overview
- The Deutscher Wetterdienst has issued widespread warnings for the weekend, with gusts up to about 80 km/h in convective areas and alerts covering hundreds of districts for wind, showers and isolated severe thunderstorms.
- Major forecast models (ECMWF, GFS, ICON) now align on a strong high‑pressure build from the southwest that should raise temperatures above 25°C at the start of next week and push much of the country into high‑summer levels by midweek (around June 17).
- Forecasters place the greatest heat risk in the south and southwest, where many sources expect 30–35°C and an elevated chance of 'Wüstentage' at or above 35°C, while a few model runs show isolated peaks approaching 40–41°C but with high uncertainty.
- The warming will increase the likelihood of strong, localized convective storms that can produce heavy rain, large hail and damaging gusts and that may locally cut peak temperatures for short periods.
- If the high pressure persists the heat could last beyond the week, raising concerns for heat‑related health strain, infrastructure stress and higher wildfire risk, but models diverge on how long the hot spell will hold after about June 23.
