Scattered showers and thunderstorms developed again throughout the day on June 6th, within a very warm, moist, and moderately unstable air mass ahead of an upper level low pressure area over Northcentral Texas. Drier air aloft began to spread northeast ahead of the low across the Ark-La-Tex, with shower and thunderstorm coverage decreasing during the mid and late afternoon hours.

The episode as NWS SHV wrote it up.
Scattered showers and thunderstorms developed again throughout the day on June 6th, within a very warm, moist, and moderately unstable air mass ahead of an upper level low pressure area over Northcentral Texas. Drier air aloft began to spread northeast ahead of the low across the Ark-La-Tex, with shower and thunderstorm coverage decreasing during the mid and late afternoon hours. However, isolated showers and thunderstorms continued to redevelop along various outflow boundaries during the late afternoon within the very warm and unstable air mass, with an isolated severe thunderstorm developing over the southern sections of Tyler in Smith County. This storm produced multiple reports of quarter to half dollar size hail before dissipating during the early evening.
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, 6:04 PM CST, 55 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Shreveport LA 704 PM CDT Sun Jun 6 2021 .AVIATION... VFR conditions will continue this evening, with isolated convection possible through mid-evening before gradually diminishing. Low MVFR cigs are expected to develop across the region between 06-10Z, with IFR/LIFR cigs developing shortly thereafter across portions of E TX/N LA/SW AR. These cigs should slowly lift/become MVFR by 15Z, although convection should begin to quickly increase across the region by the mid and late morning hours. Have delayed VCTS mention until that time areawide, with convection becoming numerous by midday as it advances E across N LA/SW AR. Cigs should remain MVFR with the convection, although some improvements to VFR are expected as the convection gradually diminishes from W to E during the afternoon. Did hang on the VCTS mention though for the afternoon as any convection may redevelop along lingering outflow bndrys. SE winds 4-8kts tonight will become S 7-10kts after 15Z, except VRB in/near the developing convection. /15/ && .PREV DISCUSSION... /issued 216 PM CDT Sun Jun 6 2021/ SHORT TERM.../Tonight through Monday Night/ Lots of instability currently residing across the Four State Region attm. This combined with PWATS over 1.7 inches and a stubborn upper trough across Central Texas/Southern Oklahoma providing the necessary forcing on it's eastern flank and you have the perfect ingredients for scattered thunderstorms and that is exactly what we see ongoing attm across portions of the region. Should see a downward turn in storm coverage beyond late this evening for most areas with the exception of our far west and northwest zones where some progs suggest nocturnal convection with better storm coverage underneath the core of the upper trough itself across S OK and N TX. Will need to watch this closely as if we can get some sort of convective complex generated to our west and northwest overnight, then its remnants would likely move our way during the day Monday. Kept categorical pops going for the day Monday before best storm coverage appears to shift to near and north of the I-20 Corridor of NE TX and N LA which includes all of S AR and SE OK as the upper trough finally begins to lift out into N AR and Missouri late Monday Night. This convection as we saw last night, will continue to be prolific rainfall producers where training takes place. While the probability of this is high, the areal coverage of this likelihood is not so will forgo the need of a Flash Flood Watch at this time. Did shave NBM temps somewhat for daytime highs on Monday, otherwise, stayed pretty close to NBM guidance through the short term. 13 && LONG TERM.../Tuesday through Sunday/ The low-pressure system that has been wreaking havoc on the Four- States region will have finally pulled northeast to start this long- term forecast. However, one system will be replaced by another, as another shortwave will be moving across the area Tuesday morning. Thankfully, this system is much more progressive than the last one, as rain chances move northeast throughout the day on Tuesday, and into Tuesday night. As this second disturbance moves out of the region, upper-level ridging will begin to build in behind it. This will allow for an extended dry period into next weekend. However, while most of the area will remain dry, not all of the area will be encapsulated in the ridge. This will result in some of our eastern zones being stuck in a NW flow pattern, which will allow for some lingering rain chances during this long-term period. With this ridge moving in, and skies starting to clear, this will also allow for temperatures to start to warm up across the region. Widespread 90+ degree temperatures look likely by Wednesday, with similar afternoon temperatures likely into next weekend. /44/ && .PRELIMINARY POINT TEMPS/POPS...
