1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched SPC Storm Reports — and showed the development severe thunderstorms across parts of eastern Nebraska, southern Iowa and northeastern Kansas during the afternoon and early evening hours on 11 June 2022. In Kansas, rows of boundary layer feeder bands could be seen flowing northeastward into the growing Mesoscale Convective System. These storms produced several tornadoes, hail as large as 5.00 inches in diameter and damaging winds as strong as 83 mph.

In the corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below), pulsing overshooting tops exhibited infrared brightness temperatures as cold as -80ºC (violet pixels embedded within areas of bright white).
