1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm), CIMSS Natural Color RGB and Dust RGB images (above) showed a pulse of blowing dust moving southward within the outflow of a severe thunderstorm in southeastern Colorado on 02 May 2021. The storm produced a tornado, large hail and wind gusts as high as 93 mph at Lamar (KLAA) at 2309... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images and “Clean” Infrared Window (10.35 µm) images (above) include time-matched plots of SPC Storm Reports of large hail produced by supercell thunderstorms that developed and moved eastward across southern Texas on 28 April 2021. Hail as large as 4.00 inches in diameter was listed in the SPC Storm Reports, but one giant hailstone... Read More

1-minute Mesoscale Domain Sector GOES-16 “Red” Visible (0.64 µm) images (above) and “Clean” Infrared Window (10.35 µm) images (below) include time-matched plots of SPC Storm Reports that were produced by a number of supercell thunderstorms that developed and moved across the Deep South and Mid-South on 25 March 2021. The highest concentration of tornadoes occurred in Alabama, including one that was responsible for multiple fatalities... Read More
