Scattered Severe Storms Bring Damaging Winds and Hail Risk to Illinois, Indiana and Missouri Monday Afternoon Through Night
INDIANAPOLIS, IN — A few severe storms are expected to develop Monday, May 4, 2026 across a broad corridor covering Illinois, Indiana, and Missouri, with scattered damaging winds and hail possible through the afternoon and into the night. Coverage will be messy and uneven rather than a organized widespread outbreak.
Where the Highest Risk Sits
The yellow Possible risk zone covers the most densely populated corridor of the threat area, centered over Indianapolis, St. Louis, Lafayette, and Springfield. Key cities directly in the highest-risk zone include Peoria, Champaign, Carbondale, Evansville, Bloomington, and Louisville. The green Low-End risk extends the outer threat northward through Chicago, Rockford, South Bend, Fort Wayne, and eastward toward Columbus, Dayton, and Cincinnati.
What Storms Will Produce
Current analysis identifies two primary hazards for Monday. Wind gusts of 60 mph or higher are the leading threat across the risk zone, capable of downing trees and power lines. Hail up to 1 inch in diameter is also possible with the stronger storm cells. Tornado potential is not highlighted in current analysis but cannot be completely ruled out with any organized supercell that develops.
Timing and Coverage
Storms are expected to develop during the afternoon hours and persist into the overnight period. Coverage will be scattered, meaning not everyone in the risk zone will see severe weather, but any storm that does develop has the potential to quickly produce damaging winds.
Forecast Confidence
Confidence in scattered severe storms across Illinois, Indiana, and Missouri Monday is MODERATE. The messy and uneven coverage makes precise impact locations difficult to pin down at this range. Keep weather alerts active throughout the day Monday.
