A vigorous upper level storm system moved out of the Inter-Mountain West and into the Southern Plains during the morning hours of November 28th. This system was very dynamic in nature as it was associated with an upper level jet of over 150kts with a low level jet in excess of 60kts across the Lower Mississippi Valley.

The episode as NWS SHV wrote it up.
A vigorous upper level storm system moved out of the Inter-Mountain West and into the Southern Plains during the morning hours of November 28th. This system was very dynamic in nature as it was associated with an upper level jet of over 150kts with a low level jet in excess of 60kts across the Lower Mississippi Valley. Despite the very strong jet dynamics associated with the system, surface based instability was severely lacking across much of the reason. For this reason, strong storms were mostly sub-severe but an isolated severe wind and small hail report were produced by thunderstorms in Northeast Texas and Northwest Louisiana.
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 Nov 28, 10:59 AM CST, 6 minutes earlier.
Area Forecast Discussion
National Weather Service Shreveport LA
1059 AM CST Mon Nov 28 2016
.AVIATION...
Strong cold front forecast to push through the forecast area this
Monday that is associated with a winter storm centered over MN. Ahead
of the cold front currently across SE OK and N central TX...strong
warm air advection to continue MVFR and IFR conditions through at
least sunset of this Monday evening.
After sunset of this evening...the cold front to push W to E into MS
during Tuesday. Accordingly...cooler and drier air behind the front
to improve conditions to VFR during Tuesday. /VIII/.
&&
.PREV DISCUSSION... /issued 537 AM CST Mon Nov 28 2016/
AVIATION...
Reduced flight categories expected through today due to
convection associated with an approaching upper level disturbance
and front. Sly to swly winds 15-20 kts with gusts to 30 kts will
continue to affect the region until after fropa. Some storms could
be quite strong, producing wind gusts in excess of 50 kts at
times. Storms will move out of the area around or just after
sunset this evening, leaving clear skies and wswly winds 5-10 kts.
VFR conditions are expected to return areawide by late this
evening. /12/
PREV DISCUSSION... /issued 317 AM CST Mon Nov 28 2016/
DISCUSSION...
Quite a dynamic weather pattern underway this morning across the
Central and Southern Plains in the form of a 530 dam trough of low
pressure cutoff from the westerlies across the Dakotas. A potent
piece of energy is quickly rotating around the base of this trough
across southern AZ/NM and will be into the TX Hill Country by 12z
this morning. Very strong upper level forcing is already underway
to our west with strong upper level divergence noted to our west
in association with RRQ of 160kt+ upper level jet. This spoke of
energy quickly ejects out of the TX Hill Country and into our
region later this morning/afternoon taking on a slight negative
tilt as it moves towards the Miss River. All this will translate
into the lower levels of the atmosphere as well with 850mb winds
expected to reach 70kts across our region later this morning as
the upper trough nears. Closer to the sfc...very strong pressure
gradient already in place as we are already seeing gusts upwards
of 30kts across portions of NE TX this morning...hence the Lake
Wind Advisory which is in effect across our western half currently
and will take effect across our eastern zones later this morning.
Dryline convection currently beginning to ignite near Abilene to
east of Wichita Falls TX but pre-dryline convection has erupted
well east of this line across portions of North Central TX into S
and E Oklahoma. This is an area of strong low level WAA regime
indicative in the thetae sfc fields with a moist nose oriented
from Central TX into East Central OK. As the low level jet
increases across our region later this morning...it will help to
drive a pseudo warm front northward from the SE TX Coast to near
the AR/LA border by 18z today as the dryline moves near or just
east of the I-45 Corridor. All this to say pre-dryline convection
is very likely across our region and will pose a severe threat
even as dryline convection nears a little later in the day. Deep
Layer shear values in the 0-6km layer are in excess of 70kts with
0-3km SRH values in excess of 500 m2/s2 with pockets even above
this associated with pre-dryline/dryline convection. This will
result in the development of low top supercells with the
possibility of tornadoes. However...and this is a big however
.pre-dryline convection may limit sfc heating and thus
instability and this could be one big fly in the ointment so to
speak with our severe weather chances today. The NAM looks way
overdone suggesting SFC CAPE values in the neighborhood of 1200
J/KG later this morning/afternoon but believe the GFS is
underdone with values not expected to exceed 250 J/KG. Damaging
winds appear to be the main threat given the strength of the
pressure gradient in place with bowing line segments likely in
addition to any discrete supercells that can develop ahead of the
dryline convection. Not to mention locally heavy rainfall will be
possible with PWATS expected to climb above 1.5 inches briefly
before we get dryslotted late in the day/this evening from the
west.
Did not make significant changes to the extended portions of the
forecast but it appears to be a wet one as rain is back in the
forecast for Tue/Tue Night timeframe as we remain in southwest
flow aloft. We finally dry out on Wed but again this is short
lived as more Pacific energy dives into the Four Corners region of
the country by Friday with strong returning flow setting up Fri
Night through the upcoming weekend.
