The animation above shows GOES-16 Band 13 Infrared imagery (10.3 µm) monitoring the development of the tornadic thunderstorm just east of Wichita that spawned the EF-3 Andover, KS, tornado (on the ground from 0110 through 0131 UTC) on 30 April 2022 (SPC Storm Reports; Write-up on storms from NWS Wichita). The storm responsible for the... Read More
On 28 April, SPC’s convective outlook showed a small region of SLGT RSK over western Nebraska, with Marginal probabilities over most of Nebraska and Kansas (link to 2000 UTC outlook). The animation above shows hourly CAPE predictions from a 3-km version of the Rapid Refresh that is run hourly and initialized with Polar Hyperspectral... 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
SPC Storm Reports from 5 April 2022 note a Tornado hit Allendale SC shortly before 2000 UTC. The animation above shows the ProbSevere (version 2 — available online here) display prior to and just after the tornado. NOAA/CIMSS ProbSevere identifies and tracks the radar feature associated with this tornadic storm. ProbSevere is designed to give... Read More
