WISCONSIN — Wisconsin could see severe thunderstorms Monday as a weather system moves across the northern Plains into the Upper Midwest, bringing the potential for large hail, damaging winds, and a few tornadoes.
According to the National Weather Service’s Storm Prediction Center, portions of Wisconsin are included in a Slight Risk for severe thunderstorms through early Tuesday morning.
Forecasters say thunderstorms are expected to move into parts of Wisconsin later Monday as storm development continues along a warm front extending eastward from the Dakotas. While the exact timing and evolution of storms remains uncertain, conditions will become increasingly favorable for severe thunderstorms during the afternoon and evening.
Meteorologists say moderate instability and strong winds higher in the atmosphere will support the development of supercell thunderstorms. If storms become rooted at the surface, they could produce all types of severe weather, including large hail, damaging wind gusts, and a couple of tornadoes.
Large hail and damaging straight-line winds are expected to be the primary threats across Wisconsin, although the tornado risk is considered more isolated.
The storm system is associated with a low-pressure area moving northward through the Dakotas, with favorable atmospheric conditions extending into the Upper Midwest. Strong wind shear and increasing instability will help support organized severe thunderstorms where they develop.
Forecasters note there is still uncertainty regarding how storms will evolve throughout the day, but residents are encouraged to monitor the latest forecasts and have multiple ways to receive weather warnings if severe weather develops.
