With the help of a relatively low sun angle, 1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm) images (above) revealed long shadows cast by peaks of the Alaska Range — especially that of Denali, located in the lower center of the satellite scene — upon the tops of stratus clouds to the north on 14 November 2020. The stratus layer was producing snow at the Minchumina Airport during the day, which in tandem with fog was reducing the surface visibility to 1 mile at 20 UTC.
