A wildfire was sparked by lightning over the Pagami Creek area in the arrowhead of Minnesota, and can be seen on the satellite image below provided by NASA. The red marks indicate “hot spots” as detected by shortwave infrared satellite imagery. Smoke can be seen moving across western Lake Superior then southeast across Wisconsin into northern Illinois. Visibilities have dropped to around 4 miles in some areas of northern Illinois, including O’hare International Airport.
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.
While conditions have improved this morning and there have been no reports of smoke, you may occasionally smell hints this morning as winds have become northwest ahead of an approaching cold front. Any further smoke particulate in the air should continue to disperse through the day.
