The radar

The Ft Polk radar (KPOE), 145 km from the middle of the area, began a volume at 20:20 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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 severe thunderstorm 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 severe thunderstorm warning went out at Nov 29, 12:52 PM CST, 1 hour 24 minutes earlier.

Area forecast discussion, Nov 29, 12:52 PM CST, 1 hour 24 minutes before
Area Forecast Discussion
National Weather Service Shreveport LA
1252 PM CST Tue Nov 29 2016

.UPDATE...
Isolated showers have developed across portions of northeast TX
and southwest AR, though within drier air. Do not expect much /if
at all/ in the way of precipitation, but have adjusted the
forecast to reflect this trend, with the showers tapering off in
the next few hours. Focus for severe thunderstorm potential
remains across portions of Deep East TX northeast towards
southwest AR and locales eastward later this afternoon.

&&

.PREV DISCUSSION... /issued 1203 PM CST Tue Nov 29 2016/

AVIATION... Scattered convection mainly south of I-20, has
increased as a warm front to the south advances nwd into the area.
 These storms continuing since early this am near the KLFK
terminal, are skirting just south of KSHV terminal, and gradually
advancing towards the KMLU terminal. A cold front will also move
across ne TX this aftn and likely a squall line to develop around
30/00z affecting mainly KMLU and KELD terminals this eve but
possibly briefly affect KSHV and KLFK near 30/00z. Stgr cells this
 aftn may contain hail and gusty winds over 40 kts, with possible
straight line winds with storms invok cold front this eve. Overall
 svr threat to progress later in day with tornadic potential over
eastern cwa. Lgt to sw winds around 10 kts expected this aftn.
Most sites outside of convection are vfr with mid lvl cloud decks
except for KMLU terminal where some ocnl IFR cigs and lowered
vsbys have persisted beyond mrng. Skies becmg vfr skc later
tonight and continue thru end of fcst period with frontal w-nw
winds around 10 kts after 30/13z./VII/.

PREV DISCUSSION... /issued 425 AM CST Tue Nov 29 2016/

DISCUSSION...
The dryline that ushered in active weather yesterday has stalled
and will washout later today. The upper level low to the west will
push a cold front through later today with a warm front moving
northeast ahead of the front. Expect an increase in clouds today
which will keep temperatures in the 70s and dewpoints in the upper
40s to lower 50s. The low level moisture along with warmer
temperatures could allow east texas and central Louisiana areas
to see severe weather later today, mainly hail and wind. The cold
front will move out early Wednesday morning with cool drier air
behind the front with surface high pressure providing subsidence
and cooler conditions during the early morning and overnight
hours. We will provide graphics about the severe weather this
morning showing the areas in the slight risk.

The next weather maker will be another trough of low pressure out
of the Pacific northwest that will move into southwestern US. The
GFS and Euro show the trough moving into the area on Saturday
with overrunning ahead of the front. The difference in the models
are in the timing of the rain ending the EURO moves the rain out
early monday while the GFS keeps the overrunning conditions into
Tuesday and early Wednesday.
