GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed thunderstorms that produced severe weather (SPC storm reports | NWS Rapid City) across parts of Wyoming, Montana and South Dakota on 01 June 2018. The SPC storm reports on the imagery are “parallax-corrected”, such that they are plotted at a location matching the corresponding cloud-top features (applying the 11-km tropopause height from the 12 UTC Rapid City rawinsonde report).

GOES-16 Mid-level (6.9 µm) images (below) revealed a shortwave trough that was moving eastward across the northern Rocky Mountains, enhancing forcing for ascent as it approached the region of developing convection.
