Milwaukee, Wisconsin – Strong storms are expected to develop within hours Monday afternoon, bringing the risk of damaging winds, large hail, and flooding that could disrupt evening travel across southern Wisconsin.
According to the National Weather Service in Milwaukee/Sullivan, storms will form late Monday afternoon and intensify into the evening, especially south of I-94. Areas from Madison to Janesville, Kenosha, and near the Illinois border face the greatest risk for severe weather, including isolated tornadoes.
Rainfall totals of 1 to 1.5 inches are likely Monday into Monday night, with localized higher amounts possible. That volume could overwhelm drainage systems, leading to ponding on roads and flooding in low-lying neighborhoods. Cities including Milwaukee, Racine, and Waukesha could see water-covered streets during the evening commute and overnight hours.
Wind gusts may reach 60 to 70 mph in stronger storms, capable of downing tree limbs and causing scattered power outages. Large hail is also possible, particularly in southwestern counties near Platteville and Monroe.
Drivers along I-94, I-43, and U.S. 41 should prepare for sudden visibility drops and standing water. Residents are urged to secure outdoor items, charge devices, and enable emergency alerts ahead of the evening.
Storms will diminish after midnight, but additional rain may linger into early Tuesday. Further updates are expected by Monday morning as confidence increases in storm timing and intensity.
