The smoke makes the air hazy and the smell of smoke may be discernable.
"The smoke from these fires rises high into the atmosphere and is driven south across the Upper Midwest by upper level winds," the NWS said on its website. "It is expected that any impact on temperatures due to filtering of the sunshine would be minor. The smoke layer is anticipated to again affect much of the area by mid week.
