A surface warm front helped to provide a focus for thunderstorm development as an upper level shortwave trough moved out of the Rocky Mountains and across the Northern and Central Plains.  These thunderstorms developed during the mid evening hours, and continued into the early morning hours of May 7th as a strong low level jet nosed into the region.  With instability as high as 1500 J/kg and more than sufficient shear present, many storms became strong to severe.  Hail up to the size of golf balls was reported, along with wind gusts near 70 mph, which did some damage across Jewell County.  Along with scattered tree damage, a steel door was blown from a building and a small hog shed was destroyed near the town of Esbon.  Approximately 20 power poles were reported to be damaged across Jewell County, along with an empty grain bin.
