1-minute
Mesoscale Domain Sector GOES-16
(GOES-East) “Red” Visible (
0.64 µm) images
(above) showed the development of supercell thunderstorms that produced tornadoes, large hail and damaging winds (
SPC Storm Reports) across parts of Oklahoma, Kansas and Missouri on
22 May 2019.
GOES-16 “Clean” Infrared Window (10.35 µm) images (below) showed the storms as they persisted into the nighttime hours — including storms that produced EF3-rated tornadoes that affected Golden City, Missouri around 0211 UTC (which was responsible for 3 fatalities) and Jefferson City, Missouri around 0440 UTC.

A closer look at 1-minute GOES-16 Infrared images for the storm producing the EF-3 tornado that affected Golden City, Missouri is shown below. A pulsing updraft with cold
(brighter white) infrared brightness temperature overshooting tops could be seen with the parent supercell as it crossed the Oklahoma/Kansas border around 0000 UTC, moved across extreme southeastern Kansas, then moved into southwestern Missouri around 0100 UTC. The
NWS Springfield damage survey listed the start time of the Garden City tornado at 0151 UTC.

About 20 minutes prior to the Jefferson City tornado, a Terra MODIS Infrared Window (11.0 µm) image
(below) displayed a well-defined
Enhanced-V storm top signature.

A closer look at 1-minute GOES-16 Infrared images for the storm producing the EF-3 tornado that affected Jefferson City (KJEF) is shown below — of note are the 2 pre-tornado updraft pulses west/southwest of KJEF at
0346 UTC and
0359 UTC, when cloud-top infrared brightness temperatures briefly cooled to -81ºC and -82ºC, respectively
(violet pixels). The
NWS St. Louis storm survey indicated that the tornado which eventually moved through Jefferson City began southwest of the city at 0420 UTC.

A few hours later, a sequence of 3 VIIRS Infrared Window (11.45 µm) images
(below) from Suomi NPP and NOAA-20 showed the line of supercell thunderstorms between 0704 and 0844 UTC.

A closer view of the Suomi NPP VIIRS Infrared Window (11.45 µm) image at 0704 UTC
(below) revealed another well defined Enhanced-V signature in far northeastern Oklahoma.

(below) depicted an example of a warm “moat” surrounding a cold overshooting top having a minimum infrared brightness temperature of -81ºC
(violet enhancement) east of Patoka, Illinois.
