Severe thunderstorms developed  over the Front Range of Colorado during the late afternoon and early evening of 18 June 2018. One of the GOES-16 (GOES-East) Mesoscale Domain Sectors positioned over that region provided 1-minute data — shown above is a comparison of “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images of these storms as they produced large hail (up to 3 inches in diameter) across parts of the Front Range Urban Corridor. SPC storm reports are plotted on the images.
