After a smoky finish to the week that saw air quality alerts impacting the Chicago area, a more pleasant start to the weekend is in store, with seasonal temperatures and cleaner air for much of the region.

Air quality alerts have expired for almost all of the Chicago area, though Northwest Indiana remains under an air quality action day.

In Northwest Indiana, conditions will remain unhealthy for sensitive groups as smoke from Canadian wildfires persists in the region.

Unhealthy air quality due to Canadian wildfire smoke is expected to persist today, mainly across parts of northwestern IN. Consider limiting or postponing prolonged outdoor activity.
