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 severe thunderstorms movng eastward across Missouri and Illinois during the late afternoon and early evening hours on 24 October 2021. Most of these storms were developing along and ahead of an advancing cold front (surface analyses), and they produced several tornadoes including a long-track EF-3 in Missouri/Illinois (NWS St. Louis) and a long-track EF-2 in Missouri (NWS Kansas City).
The corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below) extended into the nighttime hours, and displayed coldest cloud-top infrared brightness temperatures in the -60 to -70ºC range (red to black enhancement).
