Summary
Chicago and the National Weather Service warned that a three-day stretch of dangerous heat will run from noon Monday to 10 p.m. Wednesday, with peak heat indices of 100-105°F.
Upper-70s to 80°F overnight temperatures are expected to limit recovery, raising health risks for seniors, children, pregnant people and residents without air conditioning or reliable hydration.
Cooling centers opened across the city and suburbs, while Chicago Public Schools moved all summer programming indoors through Wednesday and ComEd increased staffing for possible outages.
State officials said the heat will extend beyond Chicago, with central Illinois forecast to reach heat indices up to 108°F and southern Illinois up to 110°F.
Meteorologists said a three-day heat event of this kind has occurred only twice since 2013, underscoring a broader warming trend that is making extreme heat more dangerous.
