Chicago, Illinois – Illinois faces a significant heat wave this weekend and into early next week, with heat index values potentially soaring above 100 degrees Fahrenheit for several consecutive days. Residents should prepare for dangerous conditions that could lead to widespread heat-related illnesses.
According to the National Weather Service Chicago, peak heat indices exceeding 100°F are possible from this weekend through early next week across the entire Chicago metropolitan area.
