Overview
- Two rounds of storms are expected, with a non‑severe morning pass followed by a stronger, focused round mainly between about 5 p.m. and midnight on Wednesday.
- The highest severe threat sits across southeastern Minnesota into western Wisconsin while much of the Twin Cities north of the Minnesota River may stay dry.
- Forecasters say individual storms could produce hail up to about 1–2.5 inches, damaging straight‑line winds up to roughly 80 mph, torrential rain, and a low‑end risk of isolated tornadoes.
- Repeated rounds of heavy rain into Thursday and Friday raise the risk of temporary urban flooding and localized flash flooding where storms train over the same neighborhoods.
- Residents in the highest‑risk corridors — including areas along I‑90 and south of the Minnesota River — are advised to monitor watches and warnings and prepare for rapid storm development and sudden severe conditions.
