The day after a powerful storm system hit the Chicago area, knocking out power to thousands and knocking over more than its fair share of trees, more stormy weather was anticipated in the Windy City Tuesday into Wednesday.
The rush-hour storm system -- a "derecho" -- brought a brief period of heavy rain, plus lightning and winds as high as 75 mph. The storm left almost 300,000 ComEd customers without power Monday, a large chunk of whom -- about 67,000 -- were still without power by mid-Tuesday morning, according to the Chicago Tribune.
According to the Sun-Times, most of the remaining power outages are focused in the city's south suburbs.
The storm also caused a temporary ground stop and many delays at O'Hare International Airport, NBC Chicago reports. Delays were also reported on at least two Metra lines as well as some CTA rail lines.
The threat for severe storms has carried into Tuesday, as the Chicago Weather Center blog notes a fast-moving band of rain and thunderstorms was expected to move through the Chicago area in the mid-to-late morning. A slight risk of storms remains in the forecast Tuesday afternoon into the evening and possibly on Wednesday as well.
