Overview
|
Numerous severe storms tracked across eastern IA, northwest IL, and northeast MO Friday afternoon and evening. Widespread wind gusts between 60-70 mph, large hail up to teacup size, and several tornadoes were reported. The most significant damage occurred in Lena, IL where many homes and outbuildings were damaged, trees uprooted, and power lines downed. Very strong winds also were reported near Washington, IA and near Colmar, IL where several outbuildings and grain bins were destroyed. NWS storm survey teams will be assessing this damage this weekend and likely into next week in collaboration with county emergency management.
