An upper level disturbance that lifted across the Rockies and into the Dakotas sent a cold front across eastern Nebraska and southwest Iowa during the late evening and overnight hours of June 26th and 27th.  In addition, a warm front extended ahead of the cold front near the Kansas border.  Moderate to high amounts of instability and wind shear allowed several clusters of severe thunderstorms to race across the area both ahead of and along the cold front.   Bowing segments across northeast Nebraska and west central Iowa produced areas of very strong damaging winds.  Slower moving supercell thunderstorms that developed north of the warm front produced a few large hail and strong wind reports in southeast Nebraska along with very heavy rainfall.
