Millions across the Midwest, particularly in Illinois and Indiana, are at risk of severe weather impacts. The primary threats include intense tornadoes capable of causing widespread destruction, damaging winds that could topple trees and power lines, and large hail that may damage property. Areas already recovering from previous storms could face additional challenges, including power outages and structural damage. The Storm Prediction Center has also issued a broader Level 3 and Level 2 risk for surrounding areas, extending the potential impact zone to cities like Kansas City, St. Louis, and Chicago.
