Milwaukee, WI – Southern Wisconsin could see renewed river flooding and dangerous travel conditions starting Friday night as multiple rounds of heavy rainfall move in through early Tuesday.
According to the National Weather Service in Milwaukee, storm systems are expected to repeatedly impact the region beginning late Friday, with rainfall rates reaching 1–2 inches per hour. Model guidance shows uncertainty in where the heaviest bands may set up, but areas from Madison to Kenosha are at risk, especially where recent rains have already elevated river levels.
Rainfall totals could exceed 3 inches in some locations, with western and central parts of the state — including Tomah and Fond du Lac — seeing a 70–80% chance of at least one inch. Farther south, probabilities remain lower, but flash flood risks are higher where storms linger. Simulated models suggest two scenarios: one keeping heavier rain north of Milwaukee, and another dragging those storms directly across southern counties overnight Friday into Saturday.
Residents near flood-prone rivers and low-lying areas are urged to assemble emergency kits and monitor local updates. Flooded roads, overwhelmed drainage systems, and travel disruptions are all possible by the weekend.
Rain chances continue through Monday night, with flash flood watches and new advisories likely if conditions worsen.
