Overview
- Tuesday delivers a brief warm, sunny spell with many regions hitting mid‑20s Celsius and the Oberrhein approaching 30 °C, giving people a last chance for outdoor plans.
- DWD has active localized warnings in parts of Upper Bavaria, including a level‑2 alert for persistent heavy rain with forecast totals around 30 l/m² and up to about 40 l/m² in orographic 'staulagen'.
- From Tuesday evening a northwest‑moving cold front is forecast to produce showers and thunderstorms that may include intense short‑duration rainfall of about 20–25 l/m², hail and gusts possibly reaching 70–80 km/h in some areas.
- Temperatures will fall sharply after the front, with many forecasts showing Wednesday highs around 17–23 °C and generally cooler, more unsettled weather for the rest of the week.
- The change follows an unusually warm 2026 summer recorded by Copernicus, and officials urge people to monitor updates because timing and intensity of convective cells remain uncertain and can affect school runs, commutes and low‑lying roads.
