The episode as NWS MEG wrote it up.
An upper level low pressure system tracked southeastward from the St. Louis area through Northeast Arkansas on August 17th, 2014. The upper level low interacted with daytime heating to produce showers and thunderstorms across the area during the afternoon and evening hours. Some storms became severe producing damaging winds. The storms diminished after sunset due to the loss of daytime heating.
