Overview
- - The advancing cold front, which arrives Sunday night, spreads rain and embedded thunderstorms from the southwest toward the northeast and cuts Monday highs to about 9–14°C in the north and center and 15–20°C in the south, according to DWD.
- - Southern Germany faces the highest convective risk with thunderstorms producing short‑term downpours of 20–30 l/m², hail, and gusts around 60–80 km/h, and some forecasters warn localized totals could reach 40–50 l/m² by Monday.
- - NRW, Lower Saxony and the northern coasts turn windier and cooler with stürmische Böen near 70–85 km/h in exposed areas and periods of heavy rain, including a risk of Dauerregen around the Harz.
- - Colder air lowers the snow line in the Alps to roughly 800–1000 meters late Monday into Tuesday with 1–10 cm of snow possible, while higher terrain in the Mittelgebirge and the Oberharz may see wet snow and pockets of ground frost.
- - The pattern echoes the “Eisheilige” cold snap common in mid‑May and could disrupt travel in uplands, dampen outdoor plans, and threaten tender crops, so residents are urged to track local DWD alerts for rapidly changing, highly regional conditions.
