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

GOES-16 (GOES- East) “Clean” Infrared Window (10.35 µm) images, with and without plots of GLM Groups (above) showed a Mesoscale Convective System (MCS) that was propagating southward across eastern Mexico (in advance of an approaching cold front) from 2001 UTC on 25 April to 1501 UTC on 26 April 2020. The coldest... 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...

A sequence of GOES-16 (GOES-East) “Red” Visible (0.64 µm), Mid-level Water Vapor (6.9 µm) and Air Mass Red-Green-Blue (RGB) mages (above) showed an occluding Hurricane Force low pressure system (surface analyses) off the US East Coast on 01 April 2020. In the Air Mass RGB images, darker red areas just south of the storm center indicated... Read More
