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 a lake effect snow (LES) band that intensified over far eastern Lake Erie, shortly before moving inland across western New York after sunset on 30th November 2024. Intermittent lightning activity was seen immediately inland as the LES band moved across... Read More
5-minute PACUS/CONUS sector Upper-level Water Vapor (6.2 µm) images with an overlay of GLM-detected Flash Extent Density from GOES-18 (GOES-West) and GOES-16 (GOES-East) (above) showed the detection of a bolide — which according to the American Meteor Society occurred around 1333 UTC on 13th November 2024.Since the bright fireball occurred at a high altitude...

The area of convection that has been percolating within the Caribbean has acquired sufficient organization and speed to be named Tropical Storm Rafael (at 2100 UTC on 4 November, near the end of the animation, above, created at the CSPP Geosphere site). The storm is approaching the island of Jamaica where Tropical Storm Warnings are in effect.1-minute... Read More
