The episode as NWS SHV wrote it up.
An outbreak of severe weather occurred across southeast Oklahoma during the evening and late night hours of April 24th. This weather was spawned by a strong area of low pressure in the upper levels of the atmosphere across Oklahoma and southern Kansas. Strong shear developed late in the day across southeast Oklahoma and the result was severe thunderstorms which produced strong and damaging wind gusts along with large hail.
