10-minute Full Disk scan GOES-18 (GOES-West) Infrared and Water Vapor images (above) showed the evolution of a mountain wave cloud south of the Brooks Range in northern Alaska on 01 March 2026. The coldest cloud-top infrared brightness temperatures were -61C (darker shades of red).A toggle between GOES-18 Water Vapor and Infrared... Read More
5-minute CONUS Sector GOES-19 (GOES-East) Near-Infrared “Snow Ice” images along with Radar Reflectivity images (above) showed a band of clouds producing precipitation that was moving southward across the North Dakota/Minnesota border region on 27 February 2026. Moderate to heavy snow produced by this feature — along with blowing snow created by strong... Read More
5-minute CONUS Sector GOES-19 (GOES-East) True Color RGB images created using Geo2Grid (above) showed aircraft glaciation trails drifting east-southeastward over southern Lake Michigan on 25 February 2026. As aircraft ascended/descended through a thin cloud layer composed of supercooled water droplets, additional cooling from wake turbulence (reference) — and/or particles from jet engine exhaust...
