Scattered thunderstorms developed and quickly intensified in the afternoon on July 17th across Northeast Texas into Southwest Arkansas, in the vicinity of a surface boundary and to the south of a mesoscale convective vortex (MCV) shifting slowly southeastward across Central Oklahoma. Strong heating of a richly moist airmass resulted in MLCAPE increasing to 1500-3000 J/kg.

The episode as NWS SHV wrote it up.
Scattered thunderstorms developed and quickly intensified in the afternoon on July 17th across Northeast Texas into Southwest Arkansas, in the vicinity of a surface boundary and to the south of a mesoscale convective vortex (MCV) shifting slowly southeastward across Central Oklahoma. Strong heating of a richly moist airmass resulted in MLCAPE increasing to 1500-3000 J/kg. Low/mid-level flow was weak across the region, but large precipitable water values and steepening low-level lapse rates were supportive of some potential for localized downbursts. A lone severe thunderstorm produced very localized wind damage in Columbia County Arkansas.
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 Jul 17, 1:36 PM CST, 3 hours 36 minutes earlier.

...New SHORT TERM, LONG TERM...
.SHORT TERM...
(This evening through Thursday Night)
Issued at 122 PM CDT Wed Jul 17 2024
Current visible satellite imagery shows a surface low spinning
across portions of Oklahoma. This low will be the catalyst for our
first round of thunderstorms through the evening hours, and into
tomorrow morning. This remnant MCS will first move east into C.
Arkansas, where some heavy rainfall may be possible overnight in
our far northern zones. Additionally, a few of these storms may
be strong to severe, with damaging winds being the primary threat
with any storm that does become severe. Thankfully, this threat
is relatively marginal, with only a marginal risk from the SPC in
place for locations north of I-20.
This MCS will begin to drop south overnight, as the cold front
begins to force its hand. Here, additional showers and
thunderstorms will be possible through the day tomorrow, with
heavy rainfall being possible with these as well. With their mid-
day update, the WPC has introduced a slight risk for excessive
rainfall for our portions of E. Texas and NW. Louisiana. Isolated
flash flooding could be possible during this timeframe, but most
guidance has this MCS progressing through the region at a rather
reasonable rate. In turn, widespread flash flooding is not
anticipated, with most locations seeing between 2-4 inches of
rainfall into Friday.

.LONG TERM...
(Friday through next Tuesday)
Issued at 122 PM CDT Wed Jul 17 2024
Longwave troughing will continue to work into the region through
the weekend, reinforcing itself into Monday. This will allow for
cooler air to remain filtering into the region, with afternoon
highs running around five degrees below normal. As better rain
chances return to the region by Monday, some locations could run
10 degrees below normal, with afternoon highs hovering in the mid
to upper-80s. Given the location of this troughing, and a few
disturbances riding the upper-level flow, rain chances will linger
for most of the long-term.

.AVIATION...
(12Z TAFS)
Issued at 641 AM CDT Wed Jul 17 2024
For the 17/12Z TAF period, VFR conditions prevail with just some
upstream cirrus spilling south of the Red River. This cirrus is
associated with convection just to our north along an advancing
cold front moving through the Southern Plains and Ozarks. Some
patchy low stratus will be possible around LFK early in the pd
before lifting into a cu field later in the day. As the front to
our north approaches our northern airspace late this afternoon,
convection will be possible around/after 18/00Z at TXK/ELD and
farther south toward our I-20 terminals by mid to late evening so
have included SHRA/VCTS at most sites. Otherwise, look for light
S/SW winds to increase by 15Z between 5-10 kts, then become more
variable by 18/00Z ahead of the approaching cold front.
