Summary
AQI in Chicago reached 156 Sunday morning, prompting an Air Quality Alert through Sunday, while parts of northwest Indiana remain under an extended alert until Monday.
Canadian wildfire smoke drove air quality into the “unhealthy” range, though conditions were far less severe than Thursday, when Chicago’s AQI peaked around 747.
Forecasters expect air quality to improve overnight into Monday as winds shift, but said smoke could return to the Chicago area later in the week.
Low visibility from the haze may delay flights at O’Hare, and Monday also brings a Level 2 severe-weather risk with midday showers and possible evening storms.
Health officials said the air is unhealthy for everyone, urging people to limit outdoor time, check home air filters, use car recirculation mode and stay hydrated.
