• Over 50 million people are under severe weather alerts, with enhanced risk areas stretching from eastern Kansas to northern Minnesota and Michigan's Upper Peninsula.
• Key transportation routes, including Interstates 35, 80, and 90, and major airports like MSP and DSM, could face significant disruptions due to the storms.
