Milwaukee, Wisconsin – Residents across Wisconsin face two rounds of potentially severe thunderstorms today, with large hail, damaging winds, and isolated tornadoes possible into early Tuesday morning.
According to the National Weather Service in Milwaukee/Sullivan, the first round is expected between 4 p.m. and 10 p.m. Monday, particularly north and west of Madison. Confidence is growing in storm development during this window, and if storms form, they could become severe quickly, bringing all major hazards. A second, more widespread threat will follow after midnight, with the strongest storms expected north of a line from Darlington to Port Washington between 12 a.m. and 4 a.m. Tuesday.
Areas including La Crosse, Prairie du Chien, and Wautoma have the highest risk overnight, with storms likely moving east toward Sheboygan and Milwaukee. Travel may become dangerous overnight, especially with the potential for large hail and isolated tornadoes. Residents are urged to charge mobile devices, secure outdoor objects, and stay off the roads during peak storm hours if possible.
Storms tonight carry medium confidence for severe potential, but uncertainty remains regarding how far south the most intense line will reach. Additional warnings or advisories may be issued through early Tuesday morning.
