About 27,000 homes remained without power Wednesday morning following the latest batch of overnight heavy rain and lightning.
ComEd stationed 400 crews Tuesday in preparation for the storm, and 150 crews worked overnight, according to the local utility. The northern region was again hardest hit, with 14,000 customers still without power as of 7 a.m.
High winds toppled trees and wires, and lightning even may have caused a house fire in Frankfort. The family who lives there wasn't home at the time, and no injuries were reported, according to fire officials.
The storms left the Chicago area with a bit of good news, as well.
The system pushed down humidity and cooled off Thursday temperatures with highs of low to mid-80s and upper 70s along the lake. A lake breeze will develop in the afternoon for extra relief, according to NBCChicago's Andy Avalos.
Some patchy fog settles in Wednesday night, and lows dip to 65 and 72 in Chicago.
Bearable temperatures continue Thursday and for most of the weekend. Showers and thunderstorms could show up on Friday, but Lollapalooza fans should get a mostly dry music festival.
