GOES-16 (GOES-East) Nighttime Microphysics RGB and Day Snow-Fog RGB images (above) showed a lake effect fog/stratus plume that was meandering slowly northward from the still-unfrozen Fort Peck Lake in northeastern Montana (just south of Glasgow) on 08 December 2022.During the hours leading up to sunrise, GOES-16 Nighttime Microphysics RGB images with an overlay of the GOES-16 Cloud Top Phase derived...

GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed the circulation associated with an anomalously-deep middle tropospheric cutoff low as it moved from northern Mexico across Texas during the 1301 UTC on 25 November to 2101 UTC on 26 November 2022 time period. Elevated convective elements rotating within the cutoff low helped to... Read More
1-minute Mesoscale Domain Sector GOES-16 “Clean” Infrared Window (10.3 µm) images (above) include an overlay of GLM Flash Extent Density — which showed rapidly-cooling cloud-top infrared brightness temperatures (and intermittent lightning) over the eastern half of Lake Erie, associated with the initial impulse of lake effect snow (LES) immediately downwind of the lake...

A toggle between NOAA-20 VIIRS Day/Night Band (0.7 µm) and Infrared Window (11.45 µm) images valid at 0805 UTC or 2:05 AM CST on 12 November 2022 (above) showed a broad plume of lake effect clouds streaming south-southwestward from Lake Nipigon, Ontario (north of Katatota Island, station CWKK) toward Lake Superior. A strong... Read More
