Smoky, hazy skies settled back over Chicago on Thursday, July 16, 2026, muting the afternoon sun and cutting the view down to roughly 3 miles near Midway, where temperatures hovered around 79°F. A persistent smoke layer is expected to hang around through much of the day, filtering the light and leaving a noticeable haze across neighborhoods northeast of the city.
Afternoon Forecast And Air Quality
Forecasters are calling for partly sunny skies with a high near 82°F this afternoon, along with a northeast breeze of 5 to 10 mph and only a slight chance of light rain. According to NWS Chicago, the Illinois EPA has issued a Red Forecast Air Pollution Action Day and the National Weather Service has posted an Air Quality Alert that runs through 12:00 a.m. CDT on Friday, July 17, 2026. Active children, older adults, and people with lung or heart conditions are advised to avoid prolonged outdoor exertion.
Friday Through Saturday: Heat And Storms
The pattern turns hotter and more humid late this week. Highs are expected to reach near 91°F on Friday, July 17, 2026, and around 92°F on Saturday, July 18, 2026, with heat-index values that may approach 100°F in some inland neighborhoods. Scattered showers and thunderstorms are possible Friday, with a better chance Saturday afternoon into the evening, when a frontal passage could bring gusty winds and localized heavy downpours.
Health And Cooling Centers
If you are sensitive to smoke or have respiratory or heart conditions, health officials say the safest move is to stay indoors with windows closed, run air conditioning if you have it, and skip strenuous outdoor activity for now. Anyone who needs air-conditioned relief can call 311 or check the city's cooling-center map and list. See the City of Chicago cooling centers for locations and hours.
Commute And Outdoor Plans
Northeasterly winds will keep the immediate lakefront noticeably cooler while inland neighborhoods run warmer and more humid, so plan outdoor time and activities with that split in mind. Reduced visibility from smoke could make afternoon and evening travel feel hazy, and if you have outdoor events on the schedule, it may be worth moving activities indoors or trimming back the most strenuous portions.
