Overview
- The DWD, which on Monday issued orange alerts for severe thunderstorms in parts of North Rhine‑Westphalia and Hesse, says a stationary zone across central Germany will trigger repeated downpours.
- Forecasts call for 30–50 liters per square meter over 48–72 hours across the midlands, with the heaviest phase late Tuesday into Wednesday before a gradual easing from the north on Thursday.
- Models and forecasters highlight Nordhessen, southern Lower Saxony, Saxony‑Anhalt and Thuringia as a likely corridor for prolonged, locally intense rain, though exact placement remains uncertain.
- Short‑lived but fierce storms could drop 20–30 liters per square meter in a short time with gusts up to 75–90 km/h and small hail, and dry April soils raise the risk of rapid runoff and flash floods in underpasses and small streams.
- A sharp temperature split will add to the contrast, with the north turning much cooler at 10–15 degrees and possible ground frost while the south stays summer‑warm near 25–28 degrees before cooling later in the week.
