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

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
