The afternoon of June 6 was hot, muggy and atmospherically unstable, with CAPE values reaching around 1,500 j/kg. A low pressure system far in the south help to initiate scattered thunderstorms around 3 p.m.
Storms were not orgnaized and fired all over Nebraska, convection was trying to shoot up all over the place but many quickly died out. One or two storms, especially one near Elm Creek lasted longer than the rest, earning a severe thunderstorm warning during the beginning of it's life. This storm too would die out rather quickly.
Direction of storm travel was odd this afternoon. Most storms travel in a southwest to northeast motion. These storms were traveling directly west. Winds aloft were blowing to the east, giving storms an appearance which didn't seem to match their motion. Storm tops were blown down shear as the bases churned ahead.

The thunderstorm over Elm Creek near the start of it's life. The clouds flattening out was a clear sign this cell was stronger than the rest. It's updraft was able to reach the tropopause, a stable layer of air high in the atmosphere. The cell began producing quarter sized hail, earning it a severe thunderstorm warning.
Messy convection and scud clouds obscure the storm approaching Lexington in the background. The storm had weakened but was still building for a short time, by 5 p.m. this storm had all but evaporated.
This thunderstorm near Loup City was displaying some interesting characteristics. Minor updrafts seemed to be forming in front of the storm as it moved from east to west, odd for thunderstorms this time of year. The winds aloft near the top of the storm were blowing east, giving the storms an elongated appearance as the base left the tops behind. This did help the storm as the rainy downdraft was separated from the warm updraft.
A closer look at the updrafts in front of the developing storm. This bubbling or roiling texture is an indication of upward motion and can easily help show if the storm is continuing to develop.
Later in the evening around 8 p.m. after most of the storms had dissipated, the remaining clouds didn't leave without a parting gift. The rays of the sun were filtered though the clouds, giving this brilliant display.
