Severe thunderstorms produced tornadoes, large hail and damaging winds across parts of Kansas, Nebraska and Iowa on 01 May 2018. A Mesoscale Domain Sector  provided images at 1-minute intervals — SPC storm reports are plotted on 0.64 µm “Red” Visible images (above) and 10.3 µm “Clean” Infrared Window images (below).

Many of the storms exhibited cloud-top signatures commonly associated with severe weather — for example, pronounced “enhanced-v” signatures with “cold/warm thermal couplets” were seen on Infrared imagery with the tornado-producing storms in northern Kansas and southern Nebraska (below), and both a well-defined “overshooting top” and an “above-anvil plume” were seen on Visible imagery with the Nebraska storm.
