Overview
- A short late‑summer heat surge peaked at the start of the week with daytime highs of about 30–33°C in southern and eastern Germany and roughly 34°C reported in parts of Austria.
- A trough and an associated cold front moving in from the northwest have prompted DWD Warnstufe Orange warnings for parts of southern Germany because of the elevated thunderstorm risk.
- Forecasters say storms may produce very localized heavy bursts of rain (roughly 15–35 l/m² in spots), hail and isolated gusts up to about 100–110 km/h that can cause sudden damage.
- The front is expected to drive a rapid temperature fall of often more than 10–15°C within about a day, leaving mid‑week conditions broadly cooler and more unsettled with highs near 15–22°C.
- Meteorologists stress strong spatial and timing uncertainty so most places will simply cool off while some towns may see flash flooding, fallen branches and travel disruption, and residents should follow local DWD alerts.
