The heat advisory for the Chicago area continues until 7 p.m. tonight, as temperatures are expected to near 100 degrees this afternoon.
The extreme heat kept firefighters busy Thursday, as they tried to cool down runners at a 5K event at Soldier Field. Plus, they were called to hose down several city bridges that expanded in the heat and got stuck in the up position.
City officials are providing cooling centers and reminding people to check on their neighbors, especially the elderly.
Emergency room doctors say they are seeing many patients for heat exhaustion.
Today’s heat index is expected to hit over 100 degrees before cooler temperatures arrive Saturday.
