Overview
- As of Wednesday, Germany remains in a cool, unsettled Schafskälte phase with the Deutscher Wetterdienst issuing regional warnings for thunderstorms, strong gusts, heavy rain and hail.
- ECMWF, NOAA/GFS and other model ensembles now align on a transition starting this weekend that should bring widespread warmth to 28–32°C by early next week and regional peaks of 34–36°C in mid‑June.
- Several forecasts and meteorologists project the first possible 'Wüstentag' (a day of at least 35°C) next week, though exact timing and peak values vary across ensemble members.
- Forecasters warn the incoming warm, moist air will raise the risk of powerful afternoon and evening convective storms capable of producing heavy rain, hail and damaging gusts even during the heat surge.
- Seasonal models from ECMWF, Copernicus and CFSv2 point to a very warm July, which would raise health, water and wildfire concerns, but experts stress notable medium‑term uncertainty and advise people to follow local DWD updates and safety guidance.
