1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Clean Infrared Window images (above) showed the thunderstorm that produced a EF-U rated tornado just east of Interstate 5 in northern Tehama County, California late in the day on 3rd January 2025 (this was the first verified tornado in the US for 2025). Cloud-top 10.3 µm infrared brightness... Read More
1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Water Vapor (6.9 µm) images (above) showed a mid-tropospheric shortwave trough that was moving inland across central/northern California — along with associated surface warm and cold frontal features on 14th December 2024. Sporadic lightning activity within a few bands of convection was indicated by GLM Flash Points. Of particular... Read More
Overlapping 1-minute Mesoscale Domain Sectors provided 30-second interval GOES-19 (Preliminary/Non-operational) “Red” Visible (0.64 µm) images (above) — which showed thunderstorms that produced hail to 1.75″ in diameter, wind gusts to 94 mph and several tornadoes (SPC Storm Reports) across parts of North Texas. eastern Oklahoma and far northwestern Arkansas on 04 November 2024.The corresponding 30-second GOES-19 “Clean” Infrared...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.3 µm) images (above) showed thunderstorms that produced several tornadoes and damaging wind gusts (SPC Storm Reports) across parts of central Oklahoma on 03 November 2024. Pulses of thunderstorm overshooting tops exhibited 10.3 µm brightness temperatures as cold as -78.6ºC (brighter white pixels embedded within dark black regions)... Read More
