Iowa, Missouri, Illinois and Minnesota Facing Significant Severe Weather Tuesday With Numerous Strong Tornadoes and Very Large Hail Threatening the Region Tuesday Night

Iowa in the Bullseye With Numerous Severe Storms Expected

Strong Tornadoes and Very Large Hail Are the Primary Threats

Scattered and Thunder Risk Extends Into Missouri and Illinois
