The episode as NWS SHV wrote it up.
Remnants of a mesoscale convective system (MCS) that developed during the early morning hours on June 7th over Eastern Oklahoma, migrated into Southeast Oklahoma, portions of Southwest Arkansas, and into extreme Northeast Texas during the afternoon hours, along a weak shortwave trough aloft that drifted south over these areas along the eastern periphery of an upper level ridge over the Southern Plains. Mesoscale boundaries from these earlier storms allowed for scattered showers and thunderstorms to develop during the afternoon during peak heating, within a hot and unstable air mass in place. Some of these storms briefly became severe over Central Red River County Texas, which produced damaging winds which downed large limbs southwest of Clarksville. These storms also moved very little and produced locally heavy rainfall in and near Clarksville, which resulted in localized flash flooding which flooded a vehicle in town. These storms quickly diminished during the evening with 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.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jun 7, 3:42 PM CST, 18 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 442 PM CDT Thu Jun 7 2018 .UPDATE... Sent a quick update to account for the higher coverage in pops northwest of the I-30 corridor for the remainder of the afternoon hours. Following along the lines of the HRRR that this convection will begin to lose its punch once it gets south and east of the I-30 Corridor later this evening. Did not touch the remaining grids or the overnight grids other than to taper pops downward during the evening. Update already sent...13. && .PREV DISCUSSION... /issued 359 PM CDT Thu Jun 7 2018/ SHORT TERM... The aforementioned MCS from central Oklahoma has finally moved into our region bringing some much needed rainfall across SE Oklahoma, SW Arkansas, and NE Texas. Short range models continue to suggest these storms will dissipate after sunset. Tomorrow, upper level ridging continues to expand northeastward into our region. This will result in increased subsidence and subsequently mostly dry conditions over the next couple of days. A few model solutions hint at some diurnally driven isolated convection generated mainly by daytime destabilization across the northern sections of the CWA, but confidence remains low at the moment, so decided to keep precip out of the forecast. Above normal temperatures will continue as daytime highs will reach the lower/mid 90s with overnight lows in the lower 70s. /20/ LONG TERM... Upper-level ridge to maintain hot and mainly dry conditions from Sunday through Tuesday with temperatures ranging from highs in the lower to middle 90s and lows in the mid 70s. An easterly moving upper-level trough traveling across the Gulf of Mexico will bring scattered showers and thunderstorms to the region on Tuesday and Wednesday. Better rain coverage can be expected across northern Louisiana and south-central Louisiana on Tuesday, with more widespread coverage across the ArkLaTex on Wednesday. Otherwise, temperatures during midweek to range from highs in the lower 90s to lows in the mid 70s. /05/ PREV DISCUSSION... /issued 136 PM CDT Thu Jun 7 2018/ AVIATION... For the 07/18z Tafs..VFR conditions will continue to prevail doing the remainder of the Taf period. Scattered CU will eventually give way to mostly clear skies after sunset across the region. However, there is currently a MCS across central Oklahoma that continues to slowly move towards the region. Models suggest it will make it into the northern portions of our CWA by late evening before dissipating. At the moment, there is no mention of -tsra in the Tafs, but may need to amend at ktxk and possible down to ktyr/kggg although confidence is low given the anticipated isolated nature of the event. Otherwise, winds will remain southerly between 5-10 mph then decrease to light/variable after sunset. /20/ && .PRELIMINARY POINT TEMPS/POPS...
