Thunderstorm Wind in Clark County, Illinois

Several large tree limbs were blown down and a roof was partially torn off a metal shed.

An upper-level disturbance interacting with a nearly stationary frontal boundary draped across northern Illinois triggered several clusters of strong to severe thunderstorms during the afternoon of June 30th. The storms initiated in Wisconsin, then tracked southeastward into east-central Illinois mainly east of the I-55 corridor. Wind gusts as high as 60-70 mph downed numerous trees and power lines, while hail as large as half dollars was reported in a few spots. Meanwhile further west, 40-50 mph winds along a thunderstorm outflow boundary blew a 6-inch diameter tree branch onto a man in Peoria. The man later died from his injuries.
