Overlapping 1-minute Mesoscale Domain Sectors provided GOES-16 (GOES-East) “Red” Visible (0.64 µm) images at 30-second intervals (above) — which showed rapidly-developing thunderstorms over northeastern Oklahoma, southeastern Kansas and southwestern Missouri on 28 April 2020. These storms developed along and ahead of an approaching cold front, and produced large hail and damaging winds (SPC Storm Reports).The corresponding 30-second GOES-16... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images, with and without an overlay of GLM Flash Extent Density (above) showed an isolated large thunderstorm moving east-southeastward across the Mexico/Texas border region during the early evening hours on 27 April 2020. Concentric storm-top gravity waves could be seen propagating radially outward from... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed thunderstorms that produced a variety of severe weather (SPC Storm Reports) across far southern Oklahoma on 22 April 2020. These discrete supercell storms developed along a cold front associated with a low pressure system moving across the region (surface analyses).GOES-16... Read More

Just one week after a deadly tornado outbreak across the Deep South, 1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) with time-matched plots of SPC Storm Reports (above) showed the development of thunderstorms over Louisiana that crossed the Mississippi border and went on to produce a long-track tornado that produced...
