GOES-16 (GOES-East) CIMSS Natural Color RGB images along with the Aerosol Optical Depth derived product (above) showed a cold front that was acting to focus a hazy band of aerosols — likely smoke — across the Upper Midwest on 06 June 2021. AOD values in the vicinity of the cold front were as high as 2.0 (darker blue).

The hazy signature of the cold frontal aerosols was better highlighted by GOES-16 True Color RGB images, created using Geo2Grid (below). One feature of interest was the group of long shadows cast by convective towers onto the top of the aerosol layer in central  Minnesota and northwestern Wisconsin.

In addition, 2 relatively long smoke plumes could be seen streaming rapidly east-southeastward across northern North Dakota.
