Overview
- The week begins broadly sunny and mild, with many forecasts showing calm conditions on Monday before instability increases from Tuesday and Wednesday.
- Meteorologists and the Deutscher Wetterdienst warn of a regional split with cooler, drier weather in the north and warmer, more storm‑prone conditions in the south and southwest.
- A brief heat pulse is expected midweek with local highs near 33–35 °C in parts of southern Germany, especially along the Upper Rhine, which will increase atmospheric instability.
- A strong cold front is forecast to arrive late Thursday into Friday and could produce heavy rain, large hail, damaging gusts and isolated tornadoes in areas where very warm, humid air meets the front.
- Major models disagree on what follows, with ECMWF and GFS offering different early‑September scenarios, so the longer‑range outlook remains uncertain and people should monitor updates from the DWD.
