Overview
- A low over Scandinavia pushed polar‑influenced air into Germany starting Sunday evening, ending the prolonged heat and dropping daytime highs into roughly 17–26°C across most regions.
- The German Weather Service issued localized warnings for showers and thunderstorms in southern areas, especially Bavaria and the Alpine foreland, citing risks of heavy rain, hail and gusts up to 100 km/h in spots.
- Rain has begun in parts of the west and south and has eased wildfire risk in places such as the Eifel, but totals are highly uneven with some models showing 20–60 l/m² through August and Alpine pockets exceeding 100 l/m².
- Experts warn short, intense downpours on dry ground can increase surface runoff and flash‑flood risk while doing little to recharge deep soil layers or groundwater that fell to alarmingly low levels over recent months.
- Forecasts diverge on persistence: European models favor a longer cool, unsettled spell through late August while U.S. guidance leaves open a chance of renewed warmth, so the medium‑range outlook remains uncertain.
