Scattered thunderstorms, a few severe, developed on a weak boundary during the afternoon of August 8th.  The boundary extended nearly north to south from east of Norfolk to east of Lincoln and Beatrice its position aided by earlier convection that tracked across northeast Nebraska and western Iowa.  Temperatures west of the boundary climbed to around 100 degrees with west to northwest winds.  Meanwhile, readings east of it were several degrees cooler with southeast winds.  The storms were further strengthened by an upper level disturbance that tracked southeast out of South Dakota which pushed a cool front south across the region.  The storms developed along the north to south boundary in Nebraska and produced pockets of strong winds and hail, some of it large, as they pushed into far southeast Nebraska and southwest Iowa.
