Overlapping 1-minute Mesoscale Domain Sectors provided 30-second interval GOES-19 (Preliminary/Non-operational) “Red” Visible (0.64 µm) images (above) — which showed thunderstorms that produced hail to 1.75″ in diameter, wind gusts to 94 mph and several tornadoes (SPC Storm Reports) across parts of North Texas. eastern Oklahoma and far northwestern Arkansas on 04 November 2024.

The corresponding 30-second GOES-19 “Clean” Infrared Window (10.3 µm) images are shown below. The coldest cloud-top infrared brightness temperatures associated with some these thunderstorms were -70 to -75ºC.
