The episode as NWS SHV wrote it up.
A weak upper trough shifted east across the High Plains/Upper Midwest during July 10th, with the tail end of this trough pushing southeast into Eastern Oklahoma and Northern Arkansas. This upper trough helped nudge a weak cool front south across Central and Eastern Oklahoma into Central Arkansas on the 10th, with compressional warming ahead of the front allowing for temperatures to climb into the middle 90s across Southeast Oklahoma, Southwest Arkansas, and East Texas. With a moist air mass already in place, moderate to high amounts of instability developed ahead of the front, with large scale forcing adequate enough near the weak front/upper trough to result in a band of strong to severe thunderstorms developing by mid and late afternoon across Southeast Oklahoma and Western Arkansas, which shifted south into East Texas during the evening. These storms produced damaging winds, which downed trees at various locations across East Texas before diminishing late.
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 10, 5:59 PM CST, 1 hour 46 minutes earlier.
Area Forecast Discussion
National Weather Service Shreveport LA
659 PM CDT Wed Jul 10 2019
.AVIATION...
For the 11/00z TAFs, a line of strong to severe convection will
progress southward across the area early in the period. These
storms should very slowly weaken by 11/06z. Most of the TAF sites
will be affected, but the latest model guidance suggests the
convection will greatly diminish before reaching KLFK. Otherwise,
VFR conditions should prevail. More scattered convection is
possible after 11/16z, mainly across Louisiana and East Texas
south of Interstate 20.

.PREV DISCUSSION... /issued 417 PM CDT Wed Jul 10 2019/
SHORT TERM...
This evening, the HRRR indicates that isolated thunderstorms will
continue to develop in an environment with strong instability
(SBCAPE 3000-5000 J/kg) and abundant moisture (PWATs near 2
inches) this afternoon into the evening. As the weak cold front
approaches from the north, lingering convection and outflow from
upstream convection will help increase chances of showers and
thunderstorms this evening for locations along the I-20 corridor
and northward.
Showers and thunderstorms will mostly diminish tonight with
chances decreasing to a slight chance overnight. Remnant clouds
from earlier thunderstorms along with cirrus continuing to filter
in ahead of the tropical system should keep skies partly to mostly
cloudy. The chance of showers and thunderstorms will increase
again tomorrow afternoon with daytime heating. With the lingering
frontal boundary there is the potential for locally heavy rainfall
thunderstorms.
For temps, another oppressively hot afternoon is expected tomorrow
with highs in the mid 90s and heat indices warming into the 105 to
110 degree range. With this in mind, a Heat Advisory remains in
place for everywhere except Red River and McCurtain counties
through tomorrow. Tonight and tomorrow night, lows will be in the
mid to upper 70s. /04-Woodrum/
LONG TERM...
The National Hurricane Center commenced advisories on Potential
Tropical Cyclone Two at 10 am CDT this Wednesday morning. For
information concerning this developing system, please refer to the
discussions and graphics from the NHC.
For Friday, with the forecast, strengthening, tropical system in
the northern Gulf of Mexico, SCT TSTMS begin to affect central LA
and deep E TX as the outer bands of the tropical system spread N
into LA.
The tropical system is then forecast by NHC to slowly move NW
through WRN LA, and center over extreme NW LA by Monday morning
shortly after daybreak. This scenario results in unsettled weather
into at least the middle of next week with SCT to numerous showers
and TSTMS. A deep tropical moisture airmass would of course result
in the potential for flash flooding issues. The main threat of
heavy rainfall will be over the eastern semicircle of the
circulation.
Fortunately, this July commenced with typical very warm conditions
with only scanty rainfall. This trend allowed antecedent soil
moisture conditions to dry and area rivers, bayous, and lakes to
recede after our rather wet winter and springtime of 2019. In any
case, our dryer than normal spell that began this July will end this
weekend into the middle of next week.
As for winds with this system, the NHC currently forecasts a
hurricane to be inland in SW LA during Sunday morning just after
daybreak. By Monday morning, NHC then forecasts a tropical
depression over extreme NA LA. Current thinking is that tropical
storm force winds during Sunday afternoon may affect our southern
sections of our southern parishes: Natchitoches, Grant LaSalle, and
possibly Sabine. Have blended our SFC winds for this weekend with
the wind forecasts from LCH. /VIII/.

Isolated to scattered showers and thunderstorms will be possible through this evening, mainly over East Texas and extreme Western Louisiana. Gusty winds, dangerous cloud to ground lightning, and brief heavy rainfall will be possible. A Heat Advisory remains in effect until early Thursday evening. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday... The combination of very high humidity and hot temperatures will result in heat index values between 105 and 110 degrees during the day Thursday. Therefore, a Heat Advisory is in effect until early Thursday evening. Isolated thunderstorms remain possible north of Interstate 20 on Thursday with scattered thunderstorms over central Louisiana. The primary threats with any storms this time of year are cloud to ground lightning, gusty winds and brief heavy downpours. During Friday and especially this weekend into early next week, thunderstorms will become much more numerous with heavier rainfall likely. A potential for flooding may arise as a tropical system develops along the Gulf Coast and then moves inland during this weekend. This system will then move over parts of our region late this weekend through early next week and keep us wet through the middle of the month. .SPOTTER INFORMATION STATEMENT...
