The episode as NWS SHV wrote it up.
An upper low pressure system drifted north over Southeast Oklahoma and Western Arkansas during the early morning hours of June 7th, with an upper level disturbance beneath the attendant trough enhancing an area of showers and thunderstorms over Southwest Arkansas. A moist and unstable air mass was in place, with weak steering also present which resulted in slow-moving storms producing locally heavy rainfall. Rainfall amounts of 3-5 inches fell from Southern Howard County across Northern Hempstead and Nevada Counties, which resulted in flash flooding over Northern Hempstead County where several roads were flooded and closed.
Another complex of showers and thunderstorms developed during the early morning hours of June 7th across Northwest Texas, and shifted east-southeast across North Texas throughout the morning, ahead of another shortwave trough that ejected east beneath an upper low pressure system that had begun to lift north across Southeast Oklahoma and Western Arkansas. The air mass ahead of this complex of storms across the Ark-La-Tex warmed considerably throughout the day, resulting in moderately unstable conditions within a marginally sheared environment. Thus, the storms intensified as they entered East Texas and remained severe and they progressed east across Southern Arkansas and North Louisiana. Trees and power lines were downed throughout the path of these storms, with a tornado briefly touching down just west of Calion, AR in Northeast Union County from a storm that developed ahead of the main line of storms. These storms exited Southwest Arkansas during the late afternoon hours.
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.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jun 6, 11:40 PM CST, 3 hours 20 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 1240 AM CDT Mon Jun 7 2021 .AVIATION... VFR conditions to deteriorate into the MVFR/IFR overnight, as low cigs develop and spread across the terminals. Additional convection is fcst to develop this morning, bringing low cigs/vsbys invof tstms as well. Overall aside from during the occurrence of convection, VFR conditions should return after about midday. Have kept the ongoing prevailing tstms through the afternoon and evening hours, but these may be more intermittent and require TEMPO groups as this timeframe nears. /12/ && .PREV DISCUSSION... /issued 1018 PM CDT Sun Jun 6 2021/ SHORT TERM.../Tonight/ Much of the isolated to sct convection has diminished with the setting sun this evening, as dry slotting has undercut the closed low which has begun to shift NE into Ern OK/NW AR, with the afternoon convection primarily outflow dominant and driven through diurnal heating. However, seeing a small line of convection that continues to propagate E across McCurtain County OK and eventually into the Nrn sections of SW AR, along the apex of the attendant upper trough which will swing E through NE TX into SW AR overnight. This convection should remain sustained through at least a portion of the overnight hours across SW AR, being sustained by a 20kt Srly low level flow, weak to moderate SBCapes of 1000-1500 J/Kg, and large scale ascent ahead of the trough. Thus, have raised pops to likely/high chance across much of SW AR, tapering pops to low chance/slight chance farther S across portions of NE TX/N LA where elevated forcing should be weaker. Wind gusts along this line of convection have remained consistent this evening across SE OK, with AWOS/OK Mesonet reports of 30-35 mph, which should remain the case through the overnight hours as it moves into SW AR while gradually weakening. Did make a few minor tweaks to min temps, mainly to lower readings across the rain cooled areas of SE OK and adjacent sections of SW AR. Otherwise, a warm and muggy night is expected, before convection increases late tonight across portions of Srn OK/N TX, before advancing E into our region throughout the day Monday. Zone update already out...grids will be available shortly. 15 && .PRELIMINARY POINT TEMPS/POPS...

20The Shreveport radar (KSHV), 155 km away, was scanning. The volume nearest the first event began at 09:01 UTC.
2 flash flood, 1 tornado, 1 thunderstorm wind, 1 flood. Local standard time, as filed.
Hempstead Road 1315 was flooded and closed due to a washed out culvert.
County Road 333 was flooded and closed due to rushing water from the Middle Fork Ozan Creek. A car attempted to cross the flooded roadway and stalled in the high water.
A tornado briefly touched down just west of the Calion community near Ricker Road. Since this weak tornado lofted dust, grass, and dirt and no damage was found, this tornado will be rated an EF-Unknown.
Several trees were blown down just southwest of Smackover.
Widespread rainfall amounts of 3-6+ inches, with isolated amounts up to 10 inches, fell across Central and Southern McCurtain County Oklahoma on June 7th-8th, resulting in widespread flooding across these areas. This did result in considerable rises along the Little River some 40-50 river miles downstream at Horatio, AR (Sevier County), which crested at 30.89 feet on June 10th, 2021. This was just above the 30ft major flood stage, although impacts were mainly confined to considerable lowland flooding of several hundred acres of grazing and farmland, along with significant backwater flooding along the Cossatot River with its confluence with the Little River north of Wilton. This high water routed downstream along the Little River south of Horatio to just northwest of the Winthrop community in Northern Little River County, where a 63 year old white female tried to paddle a small boat down a country backroad off of LR-52 to her cabin along the Little River during the night of June 10th. Unfortunately, her boat capsized with the victim drowning due to the strong currents. Her body was not found until June 11th, after the Arkansas Game and Fish Commission initiated a search for her.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
