Consider the rocking animation (if you click on it) of 1-minute visible imagery, above, showing the high plains of West Texas from 1900-2030 UTC on 7 May 2020. A dryline is present; can you predict from this imagery where convection will initiate? (Will it? Spoiler alert: Yes, and Yes!)The Split... Read More
A cold front with ample moisture and instability ahead of it spawned numerous strong storms in the Southeast U.S. yesterday; particularly one long-lived supercell in South Carolina. A convolutional neural network model (CNN) was deployed in realtime on the 1-min GOES-16 mesoscale sector imagery. The model produces an “Intense Convection... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed a long-lived Mesoscale Convective System (MCS) or derecho that produced a swath of large hail and damaging winds (SPC Storm Reports | NWS Nashville) from eastern Kansas to central Tennessee, northern Mississippi and northern Alabama on 03 May 2020.The corresponding GOES-16 “Clean” Infrared Window (10.35 µm)...

Overlapping 1-minute Mesoscale Domain Sectors provided GOES-17 (GOES-West) “Red” Visible (0.64 µm) images at 30-second intervals (above) — which showed thunderstorms that produced large hail and damaging winds across parts of southern Idaho (SPC Storm Reports) on 30 April 2020.To the south, strong winds at the surface were lofting plumes of blowing dust from Carson Sink in...
