The episode as NWS SHV wrote it up.
A complex of thunderstorms moved out of southern Oklahoma and north central Texas during the predawn hours of June 14th. These thunderstorms developed in a very unstable airmass along a diffuse frontal boundary. The storms migrated eastward towards a strong instability axis and ended up producing some damaging wind gusts across southwest Arkansas.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
