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) “Red” Visible (0.64 µm) images (above) showed widespread events of severe weather (SPC Storm Reports) associated with a large occluding low pressure system and its frontal boundaries on 28 March 2020.The corresponding GOES-16 “Clean” Infrared Window (10.35 µm) images are shown below. The coldest cloud-top infrared brightness temperatures were in the... Read More
