The National Weather Service says the smell is actually coming from fires in Kansas, about 600 miles away.
Any early risers out there may smell smoke. Have no fear - there are no fires nearby. The smoke is actually from Kansas, traveling some 600 miles overnight with the strong southwest winds. #ilwx #inwx— NWS Chicago (@NWSChicago) December 16, 2021
The smell is being transported by the strong winds from the south and southwest that have been moving across the Midwest Wednesday and Thursday.
