Skies over much of Minnesota looked — and smelled — much clearer and cleaner Sunday, with the most troublesome air from Canadian wildfires moving east into Wisconsin.

Minnesota is experiencing its longest air quality alert on record — seven days. The alert will remain in effect until noon on Monday, Aug. 4. It’s the result of Canada’s second most severe fire season yet.
