Overview

• Showers and isolated strong thunderstorms develop in the west and southwest on Monday, with a risk of heavy rain from the Eifel to the Upper Rhine lowlands.
• Eastern regions stay brighter and milder at first, with highs around 21–25 °C from the Baltic Sea to the Erzgebirge.
• Rain persists into Tuesday with nocturnal intensification, though the heaviest totals remain uncertain; forecasters cite North Rhine‑Westphalia as a potential focus.
• High‑resolution private outlooks project 20–40 l/m² in a few hours, locally up to 60 l/m² in six hours, raising the risk of flash flooding.
• Temperatures fall into midweek—such as in Baden‑Württemberg from roughly 20–24 °C Monday to 15–19 °C Wednesday—with a calmer window expected Thursday before further regional showers later.
