The episode as NWS SHV wrote it up.
A large complex of showers and thunderstorms moved into Northeast Texas during the early morning hours of May 8th, with this complex slowing as it moved into Harrison County. Additional showers and thunderstorms containing heavy rainfall redeveloped over the same areas of western and central Harrison County, with rainfall amounts of three to in excess of six inches falling in a couple of hours, resulting in significant flash flooding near Hallsville and Marshall.
Other scattered showers and thunderstorms developed during the mid evening hours on May 8th over northern Red River County Texas, along a weak surface front and ahead of an upper level disturbance approaching from the west. These showers and thunderstorms intensified and slowly drifted northward into southern McCurtain County Oklahoma, producing damaging winds, small hail, and flash flooding in southern McCurtain County and flash flooding over Northwest Red River County. These storms weakened during the late evening due to the loss of heating and instability.
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.
