Peoria, Illinois – A volatile severe weather setup could bring strong tornadoes, giant hail, and damaging winds across parts of Missouri, Illinois, and eastern Iowa Tuesday afternoon into the evening.
According to severe weather outlook guidance analyzing Tuesday’s environment, thunderstorms are expected to develop across Missouri during the afternoon before intensifying and moving northeast toward Illinois and Iowa during the evening hours. Meteorologists say conditions may support rotating supercells capable of producing strong tornadoes.
The corridor from northeast Missouri through central Illinois and into eastern Iowa could see the greatest risk. Cities including Peoria, Bloomington, Davenport, and surrounding communities near the Mississippi River may experience the most intense storms if supercells remain isolated during the early stages of development.
Very large hail exceeding 2 inches in diameter is also possible with the strongest storms, along with damaging wind gusts above 60 mph. As storms grow and organize later Tuesday evening, clusters of thunderstorms may spread severe wind across a broader portion of the region.
Residents across Illinois, eastern Iowa, and northern Missouri should closely monitor weather alerts Tuesday afternoon and ensure they have multiple ways to receive warnings in case tornado warnings are issued.
Additional watches and outlook updates are expected Tuesday as meteorologists refine the highest-risk areas ahead of storm development.
