Chicago, IL – Hazy skies and poor air quality lingered over Chicago and northern Illinois on Wednesday, as wildfire smoke from distant blazes continued drifting across the region. The National Weather Service (NWS) in Chicago issued an advisory highlighting air quality concerns, especially for sensitive groups such as children, seniors, and individuals with respiratory conditions.
Smoke to Ease, But Dangerous Heat Moves In
While the haze is expected to gradually lift by Thursday as southerly winds arrive, a new weather threat is quickly emerging: oppressive heat and humidity. Starting Friday, daytime highs will soar into the lower 90s, with heat index values climbing close to 100°F. The worst conditions are expected in Chicago’s urban core and surrounding suburbs during the peak afternoon hours through Sunday.
“Outdoor plans may be impacted by both poor air quality and excessive heat,” warned the NWS.
Little Relief at Night for Chicago Residents
Adding to the discomfort, overnight temperatures will offer minimal relief, with lows hovering in the upper 60s to mid-70s. Neighborhoods close to Lake Michigan may experience slightly cooler conditions due to the lake breeze, but most inland areas will feel the full brunt of the heat.
Fog, Smoke, and Health Precautions
The combination of haze, humidity, and stagnant air may contribute to patchy fog, particularly during early morning hours. Visibility could drop temporarily, and air quality alerts may change throughout the day.
Residents are advised to:
- Limit outdoor activity
- Stay hydrated
- Check on elderly or vulnerable neighbors
- Use air purifiers indoors if possible
“If you feel lightheaded or experience shortness of breath outdoors, seek shade or head indoors immediately,” advised local health officials.
Chance for Storms Late Weekend
Some relief may come Sunday as the chance for scattered thunderstorms increases. However, meteorologists warn that temperatures will remain high and humidity may worsen before conditions improve.
Weather experts also caution that additional advisories may be issued, depending on how the smoke and heat patterns evolve.
