Dangerous heat is moving into the Chicago area starting Monday, with heat index values over 100 forecast.
The National Weather Service has issued an Extreme Heat Warning for Cook County from noon Monday until 10 p.m. Wednesday.
The NWS also issued a Heat Advisory for Boone, McHenry, Lake (Ill.), DeKalb, Kane, DuPage, LaSalle, Kendall, Grundy, Kankakee, Will, Lake (Ind.), Porter, Newton, Jasper, and Benton counties from noon Monday until 10 p.m. Wednesday.
The combination of heat and humidity may make it feel around or above 100 for several days in a row.
ABC7 Accuweather Meteorologist Tracy Butler said it will be hot even along the lakefront.
Monday’s highs are forecast for the mid 90s, with heat index values between 100-105 degrees with dewpoints in the 70s, Butler said.
The best way to avoid heat-related illness and stay safe is to stay indoors and use fans and air conditioning to keep your home cool, limit your time outdoors, stay out of the sun, wear loose, light clothing and drink lots of water and fluids to remain hydrated.
The city set up cooling centers across Chicago.
People can also find relief at one of the city’s public libraries, Chicago Park District fieldhouses, as well as pools and splash pads.
It’s important when the temperatures climb to these extreme levels, to check on your relatives, neighbors, seniors, and those who are more vulnerable.
You can always request a well-being check by calling 3-1-1.
Mayor Brandon Johnson and city leaders plan to speak more about the extreme heat – and resources available at a news conference Monday morning.
