Overview
- Showers and isolated thunderstorms spread from the west Tuesday into Wednesday, with DWD flagging short‑term heavy rain around 15 l/m² and gusts up to 70–80 km/h in parts of NRW and the north.
- Early in the week temperatures still reach about 14–20°C, but a broader shift to unsettled westerlies brings more cloud, rain bands and fresher winds, especially near the North Sea and in higher terrain.
- Regional contrasts persist: the east and southeast stay drier and sunnier longer, while the west and northwest see earlier rain, gusty conditions and the greatest chance of lightning.
- Forecast models agree on a downturn by the weekend but differ on timing and severity, with GFS pointing to a sharper drop Saturday and ECMWF favoring a later, less abrupt slide.
- By Saturday–Sunday many areas cool into single digits or low teens, and brief wet snow or graupel is possible over the Mittelgebirge, Black Forest and Alps, with any accumulations mainly transient; a rebound toward milder conditions next week is possible.
