A comparison of GOES-15 (GOES-West), GOES-17 and GOES-16 (GOES-East) Visible images (above) showed thunderstorms which produced tornadoes, large hail and damaging winds (SPC storm reports) from southeastern Wyoming to eastern Colorado on 29 July 2018. The images are displayed in the native projections of each satellite; images from GOES 16/17 are at 5-minute intervals, while those from GOES-15 are at intervals ranging from 4 to 30 minutes (depending on the operational scan schedule for that GOES-West satellite).

The first infrared images (NOAA/NESDIS News) from GOES-17 (below) also showed the development of these severe thunderstorms. The coldest cloud-top Infrared Window (11.2 µm) brightness temperatures over eastern Colorado were around -70ºC (dark black enhancement) after about 2200 UTC.

Images from all 16 spectral bands of the GOES-17 ABI are shown below. Prior to the development of convective storms, mountain waves could be seen over Wyoming and Colorado on Water Vapor bands 8 (6.17 µm), 9 (6.93 µm) and 10 (7.34 µm).
