Recent warmer weather has caused the snow cover to retreat north into Illinois and Indiana. A small area of snow cover also extends down into portions of southeast Missouri, mainly north of Cape Girardeau. Kentucky Lake and Lake Barkley can be seen as the darker, less reflective spots that run north-south near the Tennessee and Kentucky border. These highly detailed observations of the Earth's surface are only possible when there are no clouds.
Some clouds are visible on the lower right side of the photo.
