Hot and unstable air, characterized by temperatures in the 90s and dew point temperatures in the 70s, stretched from eastern Kansas into south central Nebraska by mid afternoon on June 17th.  Northeast of that region, over most of eastern Nebraska, temperatures were also quite warm, in the upper 80s to lower 90s, but dew point temperatures were a bit lower, mostly in the 60s.  Supercell thunderstorms developed along this moisture discontinuity near the Kansas border during the early afternoon hours.  At least one of these storms produced a tornado.  Later in the afternoon and into the evening other storms that developed in central Nebraska on the nose of the warm and unstable air moved across the region producing mainly large hail but also areas of damaging winds.
