What happened
The episode as NWS SHV wrote it up.
The remnants of a complex of showers and thunderstorms that diminished during the morning hours of August 30th over Southern Oklahoma and Western Arkansas sent a large outflow boundary south into Northern and Eastern Texas during the late morning through the afternoon. Strong heating and instability ahead of this boundary resulted in additional scattered shower and thunderstorm development over much of North Texas and the DFW Metroplex, with another complex of showers and thunderstorms over this area building east into portions of East Texas during the late afternoon and evening hours before gradually weakening. Convective boundaries from this complex of storms, as well as the early morning storms interacted with the strong heating and instability that had developed over East Texas, such that isolated to scattered showers and thunderstorms developed during the mid-afternoon through the evening hours. One thunderstorm became severe over portions of Gregg and Harrison Counties, which downed a couple of trees and snapped large branches near Hallsville and Scottsville. These storms weakened by mid-evening with the loss of heating and instability.

Area forecast discussion, Aug 30, 1:31 PM CST, 3 hours 49 minutes before
Area Forecast Discussion National Weather Service Shreveport LA 231 PM CDT Fri Aug 30 2019 .SHORT TERM.../Tonight through Saturday Night/ Isold to sct convection ongoing across parts of the region will continue through sunset. Of greater concern, however, is the sub-severe MCS across N TX. The latest HRRR run seems to indicate that it will not make much if any ewd progress today before dissipating. Our region remains at the outlet of the upper ridge to our w and a trof over the Mid and Upper MS River Valley, and this has set up a sort of quasi-nw flow scenario that would be more common to us during early June. A good bit of uncertainty exists, as no model, even the hi-res output, is handling this setup well. There do, however, seem to be some signals that we could see a repeat of last night, so have maintained some PoPs across our nw after midnight tonight through much of Saturday. For temps, have trended near and just below the NBM, and even lower across our I-30 and nwd areas due to the possibility of residual morning convection. /12/ .LONG TERM.../Sunday through Thursday night/ Upper-level ridge centered across the Texas Panhandle to become firmly established across the region by Sunday and remain the dominant weather feature through next week. With upper-ridge in place, Hurricane Dorian is forecast to track northward across the east coast from mid to late week providing very little impact to the ArkLaTex. Temperatures going into early September will remain in the mid to upper 90s areawide with very little precipitation expected. /05/ && .PREV DISCUSSION... /issued 213 PM CDT Fri Aug 30 2019/ AVIATION... Isold to sct convection will continue to be possible through this aftn, and perhaps during the overnight and early morning hours Saturday. Uncertainty too high to include in TAFs attm, so will cover with AMD. Otherwise, VFR conditions to prevail with light winds and generally sely winds throughout the pd. /12/ && .PRELIMINARY POINT TEMPS/POPS...
