The AirMass RGB from GOES-16 at 0800 UTC on 20 January 2021 showed a distinct color change across central Missouri, from red to green. The enhanced red coloring suggests a large difference in water vapor brightness temperatures. The toggle above (including an image with NUCAPS* sounding points), shows structures in... Read More
The Storm Prediction Center in Norman issued a Slight Risk (click for map, from here) of severe weather over portions of southeast TX on 6 January 2021. The Day Cloud Phase Distinction RGB, shown above (click the image to animate) shows a developing line of convection stretching through the SLGT RSK area... Read More
GOES-17 (GOES-West) Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) revealed cold thermal signatures (brighter shades of white) associated with the highest-elevation portions of the Alaska Range on 05 December 2020. Note the slight northward shift (16-20 km, or 10-12 miles) in the apparent location of Denali... Read More
Late November is a time when cold outbreaks can pass over relatively warm Great Lakes waters (click here for recent observations) and produce lake-effect snow. Gridded NUCAPS observations derived from NOAA-20 CrIS and ATMS data, above, shows a large area with temperatures colder than -12ºC over northwest Ontario and northern Minnesota,... Read More
