GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) showed the development of multiple clusters of thunderstorms that were responsible for producing heavy rainfall and flash flooding across parts of eastern Kentucky during the nighttime hours leading up to sunrise on 28 July 2022. The coldest GOES-16 cloud-top infrared brightness temperature associated with these thunderstorms was -82.7ºC at 0431 UTC (within the small cluster of violet pixels over Jackson, Kentucky KJKL).

In a toggle between NOAA-20 VIIRS Infrared Window (11.45 µm) images valid at 0634 UTC and 0814 UTC (below) the coldest cloud-top infrared brightness temperature was -83ºC (just northeast of Hazard, Kentucky at 0814 UTC). These NOAA-20 images were downloaded and processed using the SSEC/CIMSS Direct Broadcast ground station, before being displayed n AWIPS.
