Overview

 

Summary

Thunderstorms developed across all of eastern Iowa, northwest Illinois and far northeast Missouri on the afternoon and evening of May 31, 2022. Initially, storms were not severe as they worked through an environment that was lacking strong mid-level instability. This changed as storms reached west central Illinois, where some atmospheric recovery was able to take place during the late afternoon hours from cloud cover during the day. An outflow boundary was also present from previous storms during the early afternoon.

A tornado warning was issued around 10:00 PM, followed by another tornado warning at 10:25 PM. A survey team has confirmed that an EF-1 tornado did touch down about 3 miles northwest of Industry, shortly after 10:30 pm, before lifting north of Industry near Highway 67. The tornado caused outbuilding, grain bin and power pole damage, but there were no injuries.

In addition, torrential rain fell across the area and led to flash flooding across southern portions of Hancock and McDonough counties. Several roads were washed out and rivers were out of their banks. The La Moine River at Colmar rose to moderate flood stage as well.
