1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) included an overlay of GLM Flash Extent Density and surface fronts — which showed severe thunderstorms that developed across southern Oklahoma (along and ahead of a cold front) and North Texas (ahead of a dryline) during the afternoon and evening hours on 16 March 2023.

1-minute GOES-16 Visible images (above) included time-matched (+/- 3 minutes) plots of SPC Storm Reports — which included a few tornadoes in Texas, hail as large as 2.40 inches in diameter in Oklahoma and 3.00 inches in Texas, and wind gusts as high as 65 knots in Oklahoma.

The corresponding 1-minute GOES-16 “Clean” Infrared Window (10.3 µm) images with plots of time-matched SPC Storm Reports (below) indicated that some of the thunderstorm overshooting tops exhibited infrared brightness temperatures in the -70 to -73ºC range (lighter gray pixels embedded within darker black regions).
