An air quality alert prompted by Canadian wildfires ended this morning (Thurs), but it’s probably far from the last one of the summer. Minnesota Pollution Control Agency’s David Brown says:
“It looks like maybe the next chance for some smoke to come into the state would be starting about, probably, Saturday night into Sunday. And right now looking at the weather models, kind of looks like the best chance would be across the Arrowhead.”
Brown expects fires across the border in Ontario and Manitoba will continue burning through the rest of the summer, perhaps until the fall when temperatures drop and maybe the state gets more rainfall. Until then, parts of Minnesota will likely continue getting doses of smokey air when winds shift to the north.
