The National Weather Service says Canadian wildfire smoke will return to Michigan Monday. Residents in northern Michigan should take precautions.

Officials said they've sent several crews to assist in controlling the massive wildfires, and they don't expect them to stop until Canada sees some snow.

Tuesday night is when the high pressure system shifts to the east, the NWS says. This should allow south winds to return, which should usher out the smoke. But then it will bring on more heat and humidity. So get ready to turn your AC back on.
