What happened

The episode as NWS LSX wrote it up.

Storm spotters reported numerous trees and tree limbs down, and some power lines down due to the fallen tree limbs in parts of Belleville, Mascoutah, and Freeburg. A subsequent damage survey done by NWS personnel discovered a downburst near the intersection of Highway 13 and Green Mountain Road about 2 miles south of Belleville. Several acres of corn was flattened by wind.
