1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched plots of SPC Storm Reports — and showed a number of severe thunderstorms which produce a tornado and a wind gust to 94 mph in South Dakota and hail as large as 4.00 inches in diameter in Wyoming on 08 June 2021. Numerous pulsing overshooting tops were evident with these storms.

The corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below) displayed cloud-top infrared brightness temperatures as cold as -75ºC with some of the more robust overshooting tops.
