Smoke from a massive wildfire in Alberta is at Minnesota's doorstep, meaning the dimmer switch on the sun will be dialed down a touch come Thursday.
The wildfire has been burning since Sunday, some 1,400 miles to the northwest of the Twin Cities in and around Fort McMurray, forcing tens of thousands of Canadians to flee their charred neighborhoods.
Drifting smoke already hovers over much of North Dakota.
Next in line is Minnesota, according to the National Weather Service in Chanhassen.
"You can see it drifting in to northern Minnesota later tonight," based on the Weather Service's computer models, said meteorologist Michelle Margraf.
By Thursday, much of Minnesota will be under a smoky blanket, but the tangible impact should be limited.
"A dimming of the sun slightly," Margraf said, "that's primarily what we're looking at."
"It won't linger for days and days," Margraf added, and it should dissipate by Friday.
