Chicago, IL – A significant heat wave is set to hit Illinois this week, with dangerously high temperatures and humidity expected to soar starting Wednesday morning and continuing through Thursday evening. The National Weather Service has issued an Extreme Heat Watch for Cook County and surrounding regions, warning of heat index values reaching as high as 115°F in some areas.
According to the NWS, the heat is expected to intensify, particularly in the northern, central, and southern parts of Cook County, including Chicago, Oak Lawn, Oak Park, and Schaumburg. The heat indices could stay above 90°F even overnight, offering little to no relief for residents until Thursday night.
The extreme heat is predicted to affect not only urban areas like Chicago but also suburban regions including Naperville, Joliet, and Kankakee. Dangerous conditions are expected along busy roads like I-90 and I-55, where drivers may experience heat-related issues such as equipment malfunctions or vehicle breakdowns.
The National Weather Service advises residents to stay hydrated, avoid outdoor activities, and stay in air-conditioned environments when possible. Vulnerable populations such as the elderly and those with pre-existing conditions are especially at risk. Neighbors should check on one another, particularly those who may not have air conditioning.

The heat watch remains in effect through Thursday evening, and additional warnings could follow depending on the intensity of the heat. Emergency response teams are monitoring the situation closely, and residents are urged to stay informed of updates.
