WISCONSIN — Parts of southern Wisconsin are under a heightened threat for severe weather, including the potential for tornadoes, as storms are expected to develop Tuesday afternoon and continue into the evening, according to the National Weather Service’s Storm Prediction Center.
The latest Day 1 Convective Outlook places areas of southern Wisconsin near an enhanced risk zone stretching from Iowa into the southern Great Lakes. Forecasters say this region could see multiple rounds of severe thunderstorms capable of producing large hail, damaging winds and tornadoes.
According to the Storm Prediction Center, several tornadoes are possible across the broader region, with some storms capable of producing strong tornadoes. A concentrated corridor of higher tornado probability extends into southern Wisconsin, including areas near Madison, Janesville and Beloit.
Meteorologists say storms are expected to develop along a boundary expected to stall from eastern Iowa into southern Wisconsin by late afternoon. As instability increases and wind shear strengthens, storms are likely to intensify quickly into supercells — the type most capable of producing tornadoes.
Large to giant hail is also expected to be a significant threat, along with damaging wind gusts. As the evening progresses, storms may organize into a larger system, continuing the severe weather risk into the overnight hours.
Residents in southern Wisconsin are urged to stay alert for rapidly changing weather conditions and be prepared to take shelter if warnings are issued.
