Overview

 

Severe thunderstorms developed across portions of eastern Iowa, northwest Illinois, and far northeast Missouri on the evening of September 18, 2022. Storms initially developed near the Iowa/Missouri border, with one storm near Bloomfield IA producing a well defined wall cloud before weakening. Storms developed, and increased in strength just east of the Cedar Rapids and Iowa City metros as they slowly tracked east around the Interstate 80 corridor. Several large hail reports were received around Durant to south of Tipton, with the highest being 2.5 inches. Storms also produced small hail and wind damage in the Quad Cities before speeding southeast into Henry County.

 

Additional storms developed along the Iowa/Missouri/Illinois tri-state area, with several tornado warnings issued. Damage was reported in southern Hancock County near Tioga, and continued south into Adams County. Additional information, including surveys, will be available Monday.
