The National Weather Service has opted to extend an air quality alert in the Chicago area for another day.

Some of the worst air quality will be right along Lake Michigan, as the majority of the Chicago metro area will be under that alert. The farthest counties like DeKalb, LaSalle, and Kankakee counties were in the clear as of Sunday. Forecast temperatures are expected to reach around 80 degrees for much of the Chicago area on Sunday.

Most of the Chicago area remains under an Air Quality Alert this weekend due to smoke from Canadian wildfires.
