1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images with time-matched plots of SPC Storm Reports (above) showed the development of thunderstorms that produced tornadoes, large hail and damaging winds in parts of southwestern Oklahoma and far northern Texas on 22 May 2020. Of particular note was the 5.33-inch diameter hail that fell in Burkburnett, Texas — reported at 2340 UTC. A number of Above-Anvil Cirrus Plume (AACP) features were seen with these storms (VISIT training).

The corresponding GOES-16 “Clean” Infrared Window (10.35 µm) images (below) revealed pulsing overshooting tops which exhibited cloud-top infrared brightness temperatures as cold as -80ºC (violet pixels). According to 20 UTC rawinsonde data from Fort Worth, Texas this temperature represented an overshoot of the Equilibrium Level of approximately 2 km.
