Storms brought a little relief Thursday for the steamy Chicago area, but a heat advisory remains in effect through Friday evening before cooler weather arrives for the weekend.
Earlier Thursday afternoon a line of storms swept through Kane and DuPage counties. A severe thunderstorm hit Sugar Grove at 3:39 p.m. with wind gusts of 69 mph. The storm moved east over Aurora, North Aurora and Batavia, and then proceeded to DuPage County.
In the wake of the storms, temperatures fell 10-20 degrees as the rain-soaked air settled over the area.
For much of the day, the entire area saw high temperatures in the 90s with high humidity and sunshine, which is made it feel like it was between 100 and 105 degrees.
The relief is likely to be temporary.
Friday should be even worse. That's when the heat index climbs to 108 degrees.
Federal weather officials say the steamy weather could cause rolling blackouts and buckled pavement.
Meanwhile, public health officials are opening cooling centers and warning people to drink plenty of fluids, check on neighbors and take precautions if they're outside.Copyright © 2013 Paddock Publications, Inc. All rights reserved.
