Smoke from wildfires in Ontario and Manitoba that pushed air quality into the “unhealthy” range over much of Minnesota yesterday (Thurs) is expected to gradually clear out today.  But relief will be short-lived because a cold front will send another shot of smoke into Minnesota on Saturday lingering into Sunday.  Officials advise limiting outdoor activity, but Nick Witcraft with the state Pollution Control Agency says if you have to be outside…

“The good thing with COVID — if you could call it good — is that a lot of people have N-95 masks, and N-95 masks would work for filtering the smoke if you’re outside.”

Forecasters expect smoke levels in Minnesota to wax and wane with the prevailing winds for the rest of the summer because the Canadian wildfires are expected to burn for a number of weeks.
