Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this tornado warning went out, 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 this tornado warning went out at Apr 6, 1:07 PM CDT, 3 hours 16 minutes earlier.

Area forecast discussion, Apr 6, 1:07 PM CDT, 3 hours 16 minutes before

Area Forecast Discussion
National Weather Service Shreveport LA
107 PM CDT Sat Apr 6 2019

.AVIATION...
For the 06/18z TAFs, widespread strong to severe convection will
affect the entire area throughout the period. The first round of
storms that is ongoing and extends back to the west into Central
Texas should move across the area during the first half of the TAF
period, and will likely end by 06/03z. Another round of strong to
severe convection will begin to develop near or just after 07/06z,
which will persist through the end of the period. KMLU may not be
impacted by the second round of storms until after sunrise Sunday
morning. Otherwise, IFR/LIFR flight conditions can be expected
with the storms. Ceilings may lift into the VFR range in locations
not experiencing convection, but patchy fog and low ceilings may
develop in some locations after sunset due to the heavy rain.

CN

&&

.PREV DISCUSSION... /issued 1149 AM CDT Sat Apr 6 2019/

UPDATE...
Convection continues to spread eastward and northeast from Central
Texas into the ArkLaTex. The warm front is still south of
Interstate 20, so the severe threat with the complex moving
through North Texas should be lower, but some marginally severe
hail or wind gusts can't be ruled out. The greater severe threat
will be in the vicinity of the warm as it moves northward through
the remainder of today and into this evening. Increasing low-level
shear along the frontal boundary will also lead to an greater
tornado threat. Thus, the Tornado Watch has been issued. The big
question is how much instability will remain in the warm sector
south of the front before additional convection currently over
Central Texas arrives later this afternoon and this evening.

Besides the addition of the Tornado Watch, high temperatures were
lowered areawide because of the ongoing rain and cloud cover. In
addition, PoPs were edited to better reflect ongoing radar trends.

CN

PREV DISCUSSION... /issued 712 AM CDT Sat Apr 6 2019/

AVIATION...
For the ArkLaTex, a good chance for popup TS today with a large
TS complex on top of that which is expected to plow into our area
out of TX this late morning and all afternoon. This feature will
impact several terminals. Gusts could become severe with hail and
isold Tornados. A large upper trough will slowly edge our way
with TS activity expected for all of Sun and part of Mon East.
Until then look for SE sfc winds and low level veering to SW by
5kft and its all SW aloft with speeds 20-45KT for flight levels.
/24/

PREV DISCUSSION... /issued 545 AM CDT Sat Apr 6 2019/

SHORT TERM.../Saturday through Sunday/

Partly to mostly cloudy and a little warmer than average with mid
50s over S OK/S AR and few upper 50s for Texarkana and Ruston and
lower 60s everywhere else. Winds are light SE or even calm here
and there.

The thunderstorms are gearing up over W central TX now and will
spread into our area later this morning and into the afternoon.
And of course we will have scattered showers and thunderstorms
possible this morning all ahead of the big complex later on. Some
may be severe today and this evening with the SPC slight and
enhanced day one. The day two is slight for still a lot of real
estate and we'll let the models figure out today, much less
tomorrow.

The WPC rainfall outlook for the short term remains impressive
and bad news for the pollen, thankfully. We can expect wide spread
inches 2 to 3 inches with 4 to 5 inch bullseyes in LA/AR. /24/

LONG TERM.../Sunday Night through Saturday/

The slow moving positive tilt upper trough is expected to drift into
Cntrl AR/ECntrl TX by Monday morning, with good agreement amongst the
progs with a nearly closed center of the trough, which would help to
enhance/maintain convection development near its center. The progs
do key in on considerable mid/upper level dry slotting which will
entrain NE just ahead of the trough Sunday night over Deep E TX and
much of N LA, which would help to diminish the more organized
convection from SW to NE during the evening and overnight hours.
Have taken this into account in the pop and QPF forecast, including
categorical pops in the evening over these areas before reducing
pops to chance after 06Z. Otherwise, the convection Monday will be
focused near the trough center as it drifts E across Srn AR/N LA,
where high chance/likely pops persist, gradually diminishing from W
to E during the afternoon.

Drier air will begin to spill SE in wake of the trough's departure
Monday afternoon/night, with any lingering isolated -SHRA exiting
the Ern zones during the evening. A NW flow aloft will commence
Monday night in wake of the trough's departure, but subsidence from
weak sfc ridging in place across the region in combination with the
dry air should allow for above normal temps areawide Tuesday as they
climb into the lower/mid 80s. This weak sfc ridging is progged to
shift E of the area by Wednesday, with a strengthening SSW low level
flow returning which should result in max temps climbing into the
mid and possibly upper 80s (as suggested by some of the MOS
guidance). The medium range progs are much more amplified this
morning with the next upper trough emerging out of the Rockies
Wednesday afternoon and into the Cntrl Plains Wednesday night. Very
strong low level and deep lyr shear is progged to be in place, but
available moisture ahead of this trough and associated cool front
will remain quite shallow as the front enters E TX/SW AR Thursday
morning. There is a little better consensus in the GFS/Canadian this
morning with enough moisture in play for isolated afternoon
convection near the front Thursday over Scntrl AR and portions of
Ncntrl LA, and thus have re-introduced slight chance pops over these
areas (especially given the strength of the large scale forcing)
over the drier ECMWF. These should diminish as they exit the region
Thursday evening, with cooler (more seasonal) and drier air spilling
SE in wake of the fropa Thursday night and Friday. This may be short-
lived though as a SE return flow commences by the end of the
extended period (Saturday) ahead of the next longwave trough that
will dig into the Desert SW next weekend and result in increased
convection once again. /15/

.DAY ONE...This Afternoon and Tonight...

A Tornado Watch is in effect until 6 PM CDT this afternoon.

Strong to severe thunderstorms are likely today ahead of a strong
upper level trough. The storms are expected to intensify as a warm
front moves northward and instability increases. The severe
weather threat should gradually diminish this evening. However,
strong to severe thunderstorms are expected to redevelop late
tonight and into the early morning hours of Sunday over portions
of East Texas.

During both rounds of severe weather, the primary threats will be
isolated tornadoes, damaging winds, and large hail. Locally heavy
rainfall may also lead to isolated flash flooding, especially
where storms repeatedly move over the same locations.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

Strong to severe thunderstorms are likely Sunday and should become
widespread by Sunday afternoon. Isolated tornadoes, damaging
winds, and large hail will be the primary threats. Locally heavy
rainfall may also lead to isolated flash flooding. The threat for
severe weather and heavy rainfall should diminish from southwest
to northeast Sunday night, but a few isolated thunderstorms may
persist until late Monday afternoon.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will likely be needed this afternoon and again
late tonight and into Sunday.
