DULUTH, Minn. – It’s the unwanted guest that won’t stay away. Another thick plume of smoke from wildfires burning in western and central Canada is blowing across the border into the Upper Midwest and Great Lakes region this week.
A plume of smoke drifted across northern Minnesota on Sunday and pushed into the Great Lakes region on Monday.

As we head toward the middle of the week, smoke-tracking forecast models predict the smoke will begin to drift into areas of the Ohio Valley and Northeast, but it’s not expected to be anywhere near as bad as what the region saw in June when smoke turned the sky above New York City an eerie orange color.

The smoke has left more than 54 million people from Minnesota to Ohio under Air Quality Alerts Tuesday, and those may expand depending on where the Canadian wildfire smoke heads next, and how thick it will be.
Nearly 1,000 wildfires continue to burn in Canada, of which over 600 are considered out of control, according to the Canadian Interagency Forest Fire Centre.
