1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Day Snow-Fog RGB and Near-Infrared “Snow/Ice” (1.61 µm) images (above) showed subtle signatures of a swath of hail covering the ground (initial storm report) — shades of red in the RGB images. and darker shades of gray in the 1.61 µm images — in the wake of a severe...

Overlapping 1-minute Mesoscale Sectors provided 30-second GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) — with time-matched plots of SPC Storm Reports — of thunderstorms that produced straight-line wind damage and hail as large as 4.25 inches in diameter across far southern Missouri and northeastern Arkansas after sunset on 15 April 2022. These storms... Read More
Previous posts on the CIMSS Blog (here, here, here) have detailed a modeling system that incorporates thermodynamic information from hyperspectral soundings (CrIS on Suomi/NPP and NOAA-20; IASI on Metop-B/Metop-C) into a version of the Rapid Refresh model. The improved definition of thermodynamic distributions by the hyperspectral data (that is: better spectral... Read More
5-minute GOES-16 {GOES-East) True Color RGB images created using Geo2Grid (below) showed widespread blowing dust (shades of tan) and wildfire smoke plumes (brighter shades of white) across much of the central/southern Plains on 12 April 2022. Wind speeds were anomalously strong behind a dryline within the warm sector of an anomalously-deep surface low, which... Read More
