GOES-19 (Preliminary/Non-operational) Day Cloud Phase Distinction RGB images (above) — created using Geo2Grid — displayed supercooled “lake effect” clouds (shades of white) streaming southeast off Lake Sakakawea in northwestern North Dakota on 25th November 2024. A smaller cloud plume was also seen streaming southeast off Devils Lake in northeastern North Dakota. Existing snow cover appeared as shades of green... Read More
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 11th 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
