GOES-16 (GOES-East) Red Visible images and the Land Surface Temperature derived product (above) showed a large area of relatively fresh snow cover across the Plains of eastern Colorado on 11 November 2024 — this deep snow cover was the result of a closed upper-level low which moved across the area 2-3 days...

NUCAPS estimates of temperature and dewpoint give swaths of information over the Arctic — a region where conventional observations are uncommon and widely spaced. The toggle above shows a disorganized low pressure system over central Alaska — light snow is widespread as shown by the surface observations, below (and in... Read More
To the CIMSS Inbox, From to the Alaska Ice Desk:I noticed what I think are a pair of mesoscale convective vorticies forming on a boundary in the southeastern Beaufort Sea between the Mackenzie River Delta and the ice pack where there's still open water. I don't think there's much impactful... Read More
GOES-East airmass RGB imagery, above, shows the evolution of a strong system that brought heavy rain to the central United States as well as snow over the western Great Lakes. The Potential Vorticity Anomaly that supported the surface cyclone, orange in the RGB shown above, starts over the Rocky Mountains and moves... Read More
