Overview
|
A cold front progressing across central Iowa helped produced showers and thunderstorms across much of the region this afternoon and evening. Thunderstorms became severe across southeast Iowa, west central Illinois, and northeast Missouri, and produced tornadoes, winds up to 80 MPH, hail up to golf ball size, and heavy rainfall amounts over 1 inch. Damage to trees and power lines were reported from Van Buren to Clark and Hancock counties. A damage survey team found two EF-1 tornadoes touched down north of Keosauqua in Van Buren County as storms moved through. Please see the Tornado tab below for additional details.
