VIIRS data from the ascending NOAA-20 overpass on 2 April 2021 — with data downloaded at the Direct Broadcast site at UW-Madison — showed predominantly clear skies over the Great Lakes. Lake ice is confined to bays on the north shore of Lake Superior, and a hint of green appears over southeastern Pennsylvania and southwestern Ohio. A larger version of this image is available here, for about a week. VIIRS imagery is routinely available from all recent overpasses and can be viewed here.
