1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched plots of SPC Storm Reports — and showed severe thunderstorms moving eastward across parts of New Jersey, New York, Connecticut, Rhode Island and Massachusetts on 13 November 2021. These storms developed along and just ahead of a cold front (surface analyses), the position of which was highlighted by an “arc cloud” extending southward across the Atlantic Ocean.

The corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below) extended past sunset into the early evening hours; the low-topped convection only displayed coldest cloud-top infrared brightness temperatures in the -40 to -50ºC range (green to yellow enhancement).
