The episode as NWS SHV wrote it up.
A weak upper level disturbance rounding a large upper level ridge of |high pressure interacted with very strong heating (as temperatures were |in the upper 90s to near 100 degrees), and available low level moisture, |to produce widely scattered showers and thunderstorms over southwest |Arkansas, which entered extreme north central Louisiana during the late |afternoon/early evening before dissipating. One particular shower |developed east of Farmerville, LA along an outflow boundary, and |produced strong but brief wind gusts that downed a tree and produced |minor roof damage to a home. The shower quickly dissipated shortly |thereafter.
