Thunderstorms developed along a dry line in western Nebraska, aided by a weak upper level disturbance.  Despite a large scale upper ridge over the plains, these storms fed on high instability that was over eastern Nebraska and western Iowa, turned severe and moved east and southeast across the region.  Outflow from the complex then fueled additional thunderstorm development over northeast Nebraska toward the end of the episode, a few of which were briefly severe with large hail.
