The Chicago area has experienced its third consecutive day of extreme heat, with temperatures reaching 94°F (34.4°C) and a heat index of 101°F (38.3°C) on Thursday.
However, the National Weather Service canceled the extreme heat warning for central and northern Cook County earlier than expected, at 10:30 a.m.

Impact & Risks

The extreme heat has posed significant risks to residents, particularly vulnerable populations such as children, the elderly, and those with pre-existing health conditions. Chicago Public Schools have moved all outdoor activities indoors to ensure student safety. The high temperatures, combined with elevated humidity levels, have increased the risk of heat-related illnesses such as heat exhaustion and heatstroke. The incoming cold front and potential thunderstorms may also bring localized flooding or hazardous conditions, though the risk is currently moderate.
