Overnight storms bring more flooding, wind damage, tornado to Chicago area
Updated on: August 10, 2026 / 1:46 PM CDT / CBS Chicago Chicagoans were likely awoken by thunderclaps as loud and intense as explosions overnight Sunday into Monday — and another round of heavy rain with flooded roads and downed trees came along with it. The overnight storms followed less than 12 hours after another round of storms likewise caused flooding and other damage around the Chicago area.

In Andersonville, a large tree limb snapped along Catalpa Avenue near Clark Street, and came down onto several cars. A large portion of the tree came down onto two or three vehicles.
