The episode as NWS OAX wrote it up.
Thunderstorms, a few severe, developed near a warm front over southeast Nebraska, during the evening of April 5. After these storms diminished by late evening, new storms developed in an area of warm advection aided by a low level jet. Although the storms primarily produced large hail, isolated storms in the late evening/early morning hours also produced damaging winds.
