Smoke Moving into Northern Michigan

Late this afternoon, a dying cool front was progressing southeastward across Michigan. Northwest winds, behind the front, were drawing smoke into Northern Michigan as well.

The image below shows visible satellite imagery from 2:45 pm. The cool front is indicated by the blue line, which has become stationary across Wisconsin and Minnesota (with the alternating red-blue). The smoke is the "hazy" looking area over eastern Lake Superior and part of the U.P.  It's easier to see when viewing a loop of satellite imagery. Click here to view a loop. After sunset, this evening, visible imagery will end for the day. So, the daylight satellite images will gradually be purged from the loop.

This smoke is associated with multiple wildfires over western Ontario, near the Manitoba border. The whisps, in the upper left of the satellite image below, are smoke plumes. There are no borders outlined on this image but, as a point of reference, the northern part of Lake Superior is in the lower right corner. Note that the smoke can also be seen over the Lake, just as with the image above. For more information, on the location of the fires, and the number of them, go to NOAA's website for analyzing fires and smoke.


The smoke plume is on the move. So, the smell of smoke won't last more than a few hours, at any one location. The visibility could be temporarily lowered to 4 to 7 miles, but the lowered visibility will not last as long as the smell of smoke in the air. Areas that will be affected, by the smoke, tonight, include the eastern U.P., northern Lake Huron and Lake Michigan, and much of northern Lower Michigan. The smell of smoke should be gone by daybreak Sunday.
