The episode as NWS SHV wrote it up.
A deep southerly flow increased across much of the Ark-La-Tex during the daytime hours of April 30th through May 1st, ahead of a slow moving upper level trough that drifted east into the Southern Plains from the Four Corners Region. A complex of showers and thunderstorms that developed over Western and Central Oklahoma during the evening of April 30th ahead of a stalled surface frontal boundary sent a cold pool southeast into portions of extreme Northeast Texas and Southwest Arkansas which eventually stalled out during the early morning hours on May 1st. Weak upper level disturbances in the southwest flow aloft ahead of the approaching trough triggered additional showers and thunderstorms across Northcentral Texas, which spread east northeast across East Texas, Southwest Arkansas, and North Louisiana during the evening hours of the 1st, and continued throughout the morning hours of the 2nd. The earlier stalled boundary over Northeast Texas and Southwest Arkansas helped to enhance the showers and thunderstorms, and coupled with the instability and deep moisture in place, some of the showers and thunderstorms became severe, producing large hail, damaging winds, and locally heavy rainfall. Isolated strong to severe storms eventually moved into portions of Western Louisiana just prior to daybreak on the 2nd, where trees were downed in Sabine Parish, and even a couple of confirmed isolated tornadoes briefly spinning up over portions of Western and Central Desoto Parish, before finally weakening by mid-morning.

Area Forecast Discussion
National Weather Service Shreveport LA
524 AM CDT Thu May 2 2019
.UPDATE.../Early This Morning/
Severe Thunderstorm Watch 119 has been allowed to expire. However,
the threat for severe weather continues across portions of Deep
East Texas. /12/
&&
.AVIATION...
Ongoing convection will affect most terminals across E TX/NW LA/SW
AR over the next few hours. Storms should diminish by later this
morning, however. Some redevelopment will be possible later today
and perhaps tonight, but will handle with AMD as needed.
Otherwise, some MVFR/IFR cigs will be possible through mid morning
and may redevelop again towards sunrise Friday. Winds will
continue generally out of the s at 10-12 kts with a few gusts
before diminishing in speed to around 5 kts overnight. /12/
&&
.PREV DISCUSSION... /issued 332 AM CDT Thu May 2 2019/
SHORT TERM.../Today through Friday Night/
The saga of this messy sw flow weather pattern continues. Much of
the ongoing convection this morning is being forced by small
disturbances that the global-scale models just aren't resolving
well. Unfortunately, the mesoscale models seem to be struggling
too. Seemingly the 3 km NAM has the best handle on the current
conditions, and it continues the ongoing convection further ssewd
across all of Deep E TX along the outflow boundary, dissipating it
as it works ewd into NW LA. Have modeled PoPs loosely on this
solution this morning. As for the ongoing Severe Thunderstorm
Watch, will trim Smith Co off, but will need to leave the
remainder through the end of the watch at 5 AM. Not sure whether
there will be another watch issuance attm.
The bigger question will be what happens later today. The
GFS/Euro/Canadian are all developing another round across SE OK
later this morning and pushing it sewd through the day. The NAM of
course is nearly void of any convection throughout today once the
morning convection dies. Tough to say exactly how things will
evolve today, but have continued with the ongoing likely PoPs for
much of the area today. We should expect that there will be some
breaks, however. Severe threat appears to be lower today as much
of the region is n of the outflow boundary, but still cannot rule
it out altogether.
As for tonight, models seem to agree that there won't be much in
the way of coverage overnight, so will allow the Flash Flood Watch
to continue and expire at 00Z. Did add a few more E TX counties
to the mix based upon what has fallen this morning. Rainfall rates
have already led to a few instances of flooding across some of
these areas, so any more storms will likely produce the same
result. As we move into Friday, additional development along the
Red River Valley of N TX/S OK looks to be the primary concern for
that time pd. Meanwhile, convection over Central TX will be making
its way newd and will move into our region Friday aftn/overnight.
Overall, the forecast remains quite complex and uncertain. /12/
LONG TERM.../Saturday through Thursday night/
The much advertised reprieve in the wet pattern is looking good as
Saturday unfolds, eventually anyway. The progs show a 1017mb high
over KN/MO nosing in over OK and TX during the afternoon. However,
the GFS/NAM push out the deeper moisture early, while the ECMWF/SREF
are both on a much slower on that pace lingering the greater QPF
signal for the day.
So we will have to wait another run or so to know any better, but
overall the expanding dry air will be arriving and pushing out the
last of the deeper moisture with at least a few hit or miss showers
perhaps into the afternoon heating or more if ECWMF is correct.
Sunday morning starts off with the high centered over much of the MS
river valley with 1015mb right over TN/KY. This is really good long
range agreement for a couple days worth of nice weather into much of
Monday with little if any QPF until that evening on GFS. The ECMWF
remains dry until Tues am, but The GFS is on the other hand, is
digging in good with a bullseye of QPF in NE TX by that time.
Either pace will see the inevitable return of the super wet SW flow
by mid to late week with likely more flooding issues and more river
issues in the process trying to crest out today's recent rains.
Meanwhile, our temperatures will remain at and above the average for
early in May. /24/

2 thunderstorm wind, 2 tornado. Local standard time, as filed.
Several large trees were snapped along Highway 174 just south of Stanley.
An EF-1 tornado with maximum estimated winds between 85-95 mph touched down along Duck Lane and continued northwest snapping and uprooting numerous hardwood trees along Highway 191. A metal awning was lifted off of the roof of a mobile home on Roberts Road. The tornado continued northwest snapping a few more trees along Straus and Roberts Roads before lifting.
Trees were blown down in Zwolle.
An EF-1 tornado with maximum estimated winds between 95-100 mph briefly touched down just southwest of the intersection of Highway 84 ad Oak Hill Road on the west side of Mansfield, snapping several trees and destroying several small sheds. The tornado also ripped the roof off of a metal awning and snapped a light pole off the concrete base, before lifting along Kings Highway prior to reaching Mansfield High School.
