GOES-16 (GOES-East) “Red” Visible (0.64 µm) images which include plots of GOES-16 Derived Motion Winds within the Suface-900 hPa layer (above) showed the eastward transport of several ice floes from the northern portion of Green Bay into Lake Michigan on 30 January 2023. Surface wind gusts and Derived Motion Wind speeds were generally in the... Read More
An animation of the Day Cloud Type RGB over Lake Superior on 30 January 2023, above, shows two prominent features: persistent lake-effect bands oriented west-northwest to east-southeast over the western four-fifths of the Lake (station KCMX on the Keewenaw peninsula, for example, observed heavy snow during this animation), and a more north-south oriented convergence band that extends from the eastern Upper Peninsula of...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) include time-matched (+/- 3 minutes) plots of SPC Storm Reports, and showed thunderstorms that produced tornadoes and damaging winds across southeast Texas and southwest Louisiana on 24 January 2023. One tornado caused EF3 damage in the Houston, Texas area. This severe convection... Read More
GOES-16 (GOES-East) Near-Infrared “Snow/Ice” (1.61 µm) images (above) displayed industrial plumes (from sources such as power plants) that produced brief periods of light snow as they drifted over a few sites in northern Wisconsin on 22 January 2023. Particles emitted from industrial stacks acted as cloud condensation nuclei, “seeding” the surrounding supercooled water cloud... Read More
