The episode as NWS SHV wrote it up.
Strong to severe thunderstorms developed along a residual outflow boundary across southern Arkansas and northern Louisiana during the late morning hours on May 8th. With a very unstable atmosphere in place...a few storms became severe and the storms propagated westward across southwest Arkansas...northwest Louisiana...and northeast Texas. The storms produced strong and damaging wind gusts...along with large hail and frequent cloud to ground lightning. A few of the storms also produced locally heavy rainfall due to their slow movement.
