Chicago, IL – Millions across the Upper Midwest and Great Lakes should prepare for the potential of severe thunderstorms Monday, with damaging winds expected to be the primary threat across portions of Wisconsin, Illinois, Indiana, Michigan, and Ohio.
According to the National Weather Service Storm Prediction Center, one or more organized clusters of thunderstorms may develop as a strongly unstable atmosphere combines with favorable wind shear across the region. Forecasters say scattered severe storms are expected, with the greatest concern centered on widespread damaging wind gusts capable of downing trees and power lines.
Large hail is also possible, and while the tornado threat appears more limited, forecasters say a few tornadoes cannot be ruled out, particularly where storms become more organized during the afternoon and evening.
The exact corridor facing the highest severe weather risk remains uncertain. Meteorologists say that will depend on how early morning thunderstorms evolve and where the atmosphere is able to recover before additional storms develop later in the day. Even with that uncertainty, conditions are expected to support severe weather across a broad area.
The enhanced risk currently stretches from southern Wisconsin through much of northern and central Illinois, northern Indiana, southern Lower Michigan, and into northwestern Ohio. Cities that could see strong storms include Madison, Milwaukee, Chicago, Rockford, South Bend, Fort Wayne, Indianapolis, Grand Rapids, Lansing, Detroit, Toledo, and surrounding communities.
Residents should stay weather-aware throughout the day, monitor updated forecasts, and be prepared to take action if severe thunderstorm or tornado watches and warnings are issued. Have multiple ways to receive warnings, especially if storms arrive after dark or while traveling.
