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
Day Night Band imagery from NOAA’s AOML Direct Broadcast site, above, shows a low-level circulation with deep convection over the center at 0719 UTC. GOES-16 Low-Level water vapor (Band 10, 7.3 µm) mesoscale sector one imagery, below, (from this website) shows abundant mid-level dry air to the south of the Nicole. Nicole is near... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Fire Temperature RGB, Shortwave Infrared (3.9 µm), Fire Power derived product and Fire Temperature derived product images (above) showed the thermal signatures associated with a wind-driven grassland fire in north-central South Dakota on 06 November 2022. The Fire Temperature and Fire Power derived products are components of... Read More
