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 UTC (SPC Storm Reports). The blowing dust eventually reduced surface visibility to 1 mile at Johnson City as it moved across far western Kansas.

1-minute GOES-16 True Color RGB images created using Geo2Grid (below) highlighted the characteristic tan-colored hues of blowing dust along and behind the thunderstorm outflow boundary.
