Overview
- The Deutscher Wetterdienst says Saturday will be mostly sunny but an unstable shift will bring showers and thunderstorms on Sunday with risks of heavy rain, hail and gusty winds in parts of the country.
- Operational models and ensembles now converge on a broad heat build‑up from about Tuesday into midweek next week with many regions again exceeding 30°C.
- Several model runs, including some GFS members, produce extreme outliers near 39–43°C around the turn of July to August but forecasters stress those peaks are uncertain and treated as probabilities rather than firm forecasts.
- Forecasters point to two amplifiers for stronger heat: Mediterranean waters that are unusually warm and very dry soils that reduce evaporative cooling and let sunlight raise air temperatures faster.
- Expected impacts include hotter nights that strain health and care institutions, higher wildfire and crop stress, and an elevated chance that intense heat phases will later trigger severe convective storms.
