GOES-16 “Red” Visible (0.64 µm) images, with SPC Storm Reports plotted in red [click to play animation | MP4]

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) highlighted the development a large and long-lived supercell thunderstorm that produced tornadoes and large hail (SPC storm reports) from northwestern Kansas to central Nebraska on 17 May 2019. Of note were the large number of tornado and large hail reports around 2259 UTC. Later in the day, concentric gravity waves were seen along the thunderstorm anvil top (for example, at 0022 UTC).

The corresponding GOES-16 “Clean” Infrared Window (10.35 µm) images (below) revealed numerous overshooting tops that exhibited infrared brightness temperatures as cold as -70ºC (black enhancement).

After the first round of severe weather from Kansas to Nebraska, additional supercell thunderstorms developed which produced tornadoes/hail/winds across southwestern and central Kansas into the nighttime hours (below).
