30-second imagery of severe thunderstorms across Nebraska and Kansas
Overlapping 1-minute Mesoscale Domain Sectors provided 30-second interval GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) of severe thunderstorms (SPC storm reports) that developed across central Nebraska and northern Kansas along and ahead of an advancing frontal boundary (surface analyses) on 08 June 2019. Robust overshooting tops were very apparent with many of the storms, and a few Above-Anvil Cirrus Plumes were also seen.The corresponding GOES-16 “Clean” Infrared Window (10.35 µm) images are shown below. Numerous overshooting tops exhibited infrared brightness temperatures in the -70 to -75ºC range; note the appearance of a wave feature which propagated radially outward from an overshooting top in south-central Nebraska after 0030 UTC.
