Overview
- The cold front from multi-core low ROSI moved in late Monday and has driven a wide shift to cooler, unsettled weather with daytime highs mostly between about 15 and 22 °C and nights falling into single digits.
- The Deutscher Wetterdienst has active Level‑2 persistent‑rain warnings for several Bavarian Alpine‑foreland counties forecasting roughly 40–60 mm of rain through Thursday and a risk of localized flooding of roads and underpasses.
- Showers and thunderstorms are spreading east and south with the DWD warning of heavy convective rain, small hail and gusts that can reach about 60 km/h or higher in exposed uplands and coastal areas.
- Operational models (ECMWF and GFS) now converge on a strong Azores high rebuilding over Europe that is expected to lift temperatures back to widely 28–32 °C and locally into the mid‑30s from the coming weekend, though the timing and peak values remain uncertain.
- The episode matches a common early‑June cool snap often called 'Schafskälte' or 'Schafskühle', with near‑term impacts on travel and lowland flooding and a short‑term outlook that shifts quickly from rain risks to heat stress if the high‑pressure scenario verifies.
