There's a write-up of last night's storms in the Trib:
Clean-up efforts were under way Tuesday morning after a line of severe thunderstorms moved through the Chicago area Monday night, downing trees and power lines, starting fires, peeling off roofs, briefly closing down both Chicago airports and ending a Cubs game after two rain delays.
As of 6:30 a.m. Tuesday, crews from the Chicago Department of Streets and Sanitation responded to reports of 1,104 damaged trees, 132 malfunctioning traffic signals, 55 damaged street light poles and 92 downed wires. The department said there were also 194 city blocks without working street lights.
