CHICAGO—(ENEWSPF)—September 13, 2011. Smoke from a large wildfire over northeast Minnesota has been moving into far northern Illinois this afternoon, due to northerly winds behind a cold front which moved across the area early this morning. Although the fire is more than 400 miles northwest of the area, the combination of sinking air and northerly winds behind the front has transported smoke all the way into northern Illinois.
The smoke will likely persist through the afternoon and into the overnight hours before winds become more westerly in advance of another cold front which will approach early Wednesday morning. Smoke will likely continue to spread to the southeast across much of northeast Illinois and northwest Indiana through this evening. Expect hazy skies and a distinct burning odor.
The Lake County Illinois Emergency Manager reports that smoke is prevalent enough to cause people to report difficulty breathing and burning of their eyes.
Individuals with respiratory problems should use caution while smoke affects the area.
