The episode as NWS SHV wrote it up.
An upper level trough over Northern Mississippi drifted west into Southern Arkansas, Northern Louisiana, and extreme Northeast Texas during June 28th, which helped to ignite scattered showers and thunderstorms over Southcentral Arkansas and Northcentral Louisiana during the afternoon and evening hours with the aid of diurnal heating and ample low level moisture. An isolated severe thunderstorm developed over Eastern Union County Arkansas by mid-afternoon, which produced damaging winds that downed trees just south of the Strong community. This storm remained strong to severe at times as it eventually drifted southwest into portions of Northcentral Louisiana.
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 28, 12:05 PM CST, 2 hours 40 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 105 PM CDT Fri Jun 28 2019 .AVIATION... Scattered showers and thunderstorms are expected to develop across much of the area later today, and into the period tomorrow. Most sites will experience predominant VFR conditions throughout this TAF period, but it's worth noting the potential for reduced visibility later this afternoon with some of these heavier thunderstorms, particularly at our eastern sites such as KELD and KMLU, where storms appear more likely. These areas can also expect a brief wind change from the north as the storms move through. We will monitor sites for this potential, and make adjustments as necessary. Pilots can also expect winds to shift to a southerly direction as these showers and storms move through the area past 29/13z. /44/ && .PREV DISCUSSION... /issued 1008 AM CDT Fri Jun 28 2019/ UPDATE... The majority of the overnight forecast package remains unchanged. After reviewing observations and trends this morning, the only big adjustments made to the package were PoP adjustments in a few places. This upper level through continues to retrograde, with storms already on the radar for most our neighbors to the east. This activity may reach our eastern zones as early as 18z (1 PM). With plenty of instability to work with, some of these storms may still reach severe levels, but widespread severe weather is not expected. The concern still remains regarding downburst potential headed into this afternoon. Instability values and dry air aloft, coupled with the weak shear present, all support the idea that some of the stronger storms this afternoon will have the potential to produce downburst wind damage with their decaying updrafts. /44/ PREV DISCUSSION... /issued 401 AM CDT Fri Jun 28 2019/ SHORT TERM.../Today through Saturday/ An upper trough over Northern Mississippi will continue to slowly retrograde towards the ArkLaTex today and Saturday. Combined with ascent from the trough, daytime heating should provide more than enough instability for scattered to widespread convection this afternoon, especially over Southern Arkansas and Northern Louisiana. If an MCS develops over the ArkLaMiss region, the cold pool from this complex could push an outflow boundary south and southwest across our area (similar to what happened over Mississippi on Thursday) resulting in additional convection over Western Louisiana and portions of East Texas. Much of this activity will be diurnally-driven and should gradually dissipate during the evening hours. It is interesting to note that several models maintain at least scattered convection overnight tonight and into Saturday as the upper trough begins to move overhead. While a couple of isolated showers or thunderstorms cannot be ruled out, increasing convective inhibition during the nighttime hours will be difficult to overcome. Therefore, only slight chance to low-end chance PoPs were carried during the nighttime hours, mainly along and south of Interstate 30. A similar situation is expected to unfold on Saturday. However, convective coverage will likely be greater across the entire area, and development may occur a few hours earlier since the upper trough will be directly overhead. Deep layer shear will not be very supportive for organized severe storms today or Saturday. However, conditions are quite supportive for downbursts, which is also suggested by an abundance of inverted-V forecast soundings from around the region. These downbursts may produce marginally severe straight-line wind gusts at times. Any storm that develops, especially storms with tall updrafts, will have the potential for downburst activity. CN LONG TERM.../Saturday Night through Thursday Night/ Upper-trough across the ArkLaTex to retrograde west on Saturday night eventually settling across central Texas by midweek. Instability associated with upper-trough combined with southwest flow aloft will allow for partly to mostly cloudy skies through Wednesday. Additionally, diurnally driven scattered showers and thunderstorms expected each afternoon, diminishing around sunset. Temperatures to range from highs around 90 with lows in the lower 70s through much of the extended forecast period. Latest forecast models are hinting at an upper-ridge building across the region by Independence day allowing temperatures to nudge up a couple of degrees and possibly limiting afternoon convection, especially across portions of northeast Louisiana and southern Arkansas. && .PRELIMINARY POINT TEMPS/POPS...
