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.  The strongest activity was confined to areas generally along and south of Highway 136, where hail up to the size of golf balls and wind gusts near 70 mph were reported.  Along with scattered tree damage, these strong winds caused damage to an empty bin at the grain elevator in the town of Chester in Thayer County.
