Powerful thunderstorms raked the Chicago area this morning, downing trees and power lines and knocking out power to about 300,000 Commonwealth Edison customers at the peak of outages.
Delays were reported on Pink and Green line trains this morning because of debris on the tracks, according to the CTA. By about 8 a.m., Pink Line service was resuming. Metra was reporting 10 to 15 minute delays throughout its system because of weather and the South Shore Line had resumed service after downed power lines halted trains to Chicago for a time.
The storm raced through the northwest and north suburbs, clocked at around 55 mph, hitting Kane and McHenry counties hard before moving through downtown Chicago about 6:30 a.m.
Winds of 70 mph hit Naperville about 6:15 a.m., and 61 mph gusts were recorded at Midway Airport just after 6:30 a.m., according to the National Weather Service. Chicago received more than 1,100 reports of downed trees and tree branches throughout the city as of about 10 a.m., according to a spokeswoman for the Department of Streets and Sanitation.
A thunderstorm watch in effect for the Chicago area until 9 a.m. was allowed to expire, but the National Weather Service warned more storms may be on the way later this morning and this afternoon.
The sky should clear late this afternoon, and the high is expected to be in the mid-80s, nowhere near as hot as Monday. But oppressively hot weather is likely to return Wednesday, with heat indices of up to 104 degrees.
As of 1 p.m. a.m., about 140,000 ComEd customers remained without power.
Trees and large tree limbs were reported down throughout the Chicago area, including a tree that fell on a home in the 2500 block of South Hillock Street in the Bridgeport neighborhood, damaging the home's roof but causing no injuries, according to the Chicago Fire Department.
