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 Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 18, 12:47 PM CDT, 51 minutes earlier.

Area forecast discussion, Apr 18, 12:47 PM CDT, 51 minutes before

Area Forecast Discussion
National Weather Service Jackson MS
1247 PM CDT Thu Apr 18 2019

.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion:
Widespread showers and thunderstorms will continue to move across
the region today. MVFR ceilings will be widespread throughout the
TAF period with patchy IFR possible. The main concern will be a
line of severe thunderstorms moving from west to east across the
area. Winds will be gusty out of the south through the day before
shifting to out of the north and remaining gusty overnight. /TW/

&&

.DISCUSSION...

A widespread severe weather episode is still expected today with
all hazards likely. A strong shortwave trough currently over the
Southern Plains will continue to lift northeast through the Lower
Mississippi River Valley today. The main surface low over northern
Michigan will continue to lift through the Great Lakes region with
an attendant cold front draped through the Mississippi Valley.
Secondary cyclogenesis is ongoing along the frontal boundary over
east Texas with a deepening low progged to lift into northern
Mississippi through the day. Widespread showers and thunderstorms
are already ongoing across portions of the Delta into central
Louisiana. The majority of this activity, especially across the
Delta, remains elevated above a slowly propagating cold pool.
Little additional forward progress of the cold pool is expected as
it encounters strengthening low-level wind fields in response to
the aforementioned deepening surface low. Warm and moist advection
across the capped warm sector will help 1000-1500 J/kg of MLCAPE
to build through the afternoon beneath strengthening vertical wind
shear, especially in the 0-1km layer.

Early morning runs of the hi-res CAM guidance continue to depict
an intense QLCS moving through the area late this morning through
the early evening hours. Ongoing upstream convection is expected
to congeal into a solid line of storms as strong forcing for
ascent and stout pressure falls overspread the area. A semi-
discrete supercell or two will also be possible ahead of the line.
Favorable parameter space will be supportive of tornadoes, both
line embedded and in any pre-line supercells, of which a few could
be strong, in addition to damaging winds of 70-80mph and isolated
hail up to quarter size. Anomalous moisture combined with heavy
rainfall rates will also lead to flash flooding as 2-4" of rain
with locally higher amounts could fall in a short amount of time.
The ongoing graphics remain on track and no major changes were
needed with this forecast update. /TW/

Prior discussion below:

Today and Tonight...Chances for severe storms and heavy rainfall
resulting in flash flooding, will be possible across the ArkLaMiss
from late this morning through early this evening.  The most intense
storms will be capable of producing winds gusts of 70-80 mph, in
addition to tornadoes, to which a strong tornado cannot be ruled
out, and hail to the size of quarters.  Also, high rainfall rates in
a short amount of time and the potential for training storms, could
result in flash flooding across the forecast area where soils are
already saturated from recent heavy rains.  Rainfall totals on the
order of 2-4 inches will be possible across the forecast area, with
localized higher amounts possible.  As a result, a Flash Flood Watch
is in effect until 10 PM tonight for the entire CWA.

A potent and still deepening mid/upper level low pressure system,
will dig south and pivot east into the Lower Mississippi River
Valley over the next 24 hours.  The resulting increased flow
throughout the atmosphere over the region ahead of it, will cause
anomalous moisture increase across the CWA, resulting in increased
instability across the forecast area through the late morning and
afternoon hours today. Wind shear values will increase across the
forecast area during this time as well.

Meanwhile at the surface, the southeast digging mid/upper level low
will be responsible for causing a strong cold front to develop
across the southern plains and stretching south into South Texas.
This front will begin shifting east towards the ArkLaMiss through
the day.  However ahead of this, a large east advancing outflow
boundary stretches southwest from the Missouri Bootheel, through the
ArkLaTex, and into South Texas.

As today progresses, this cold pool(s) will continue its east
advancement, but should weaken at bit through the early morning
hours due to a diurnal heating minimum.  However, as heating ensues
from the late morning through the afternoon hours, instability, wind
shear, and ascent increase across the forecast area as a surface low
develops and lifts northeast through the CWA.  This will result in
robust thunderstorms developing and becoming organized out ahead of
the aforementioned cold front.  It'll again be during this time,
late morning through early evening, when the chances for severe
thunderstorms and flash flooding increase across the entire
ArkLaMiss.

High-res models are in good agreement and continue to indicate the
overall mode of convection being in the form of an intense QLCS
shifting east across the forecast area.  With bowing segments
expected within this line, damaging straight-line winds are
expected, in addition to the potential for tornadoes spinning up
along breaks in the line.  Some models also continue to indicate the
potential for discrete supercells lifting northeast across mainly
southern Mississippi ahead of the QLCS.

The tightening pressure gradient over the area both pre and post-
frontal, will result in gusty southerly winds today and gusty
northerly winds this evening and overnight.  Surface winds could
become sustained between 15-25 during this time, with gusts between
25-35 mph possible.  As a result, I've introduced a "Limited" threat
for strong gradient winds across the entire ArkLaMiss into the HWO
for today into tonight. /19/

Friday through Saturday night...a deepening upper trough will dig
southward through the MS Valley and eventually close off to form
an impressive low over the TN Valley. Resulting cold cyclonic
flow above the ArkLaMiss region will support scattered to numerous
showers Friday as substantial instability develops even with
afternoon surface temperatures only in the mid/upper 50s. Some
thundershowers and perhaps even small hail could develop during
the afternoon given the steep lapse rates and low freezing levels.
In any case, expect much below normal temperatures for this time
of the year with breezy northwesterly surface wind and
clouds/precip making for uncomfortable mid April conditions. As
we go into the weekend, precip chances will end and conditions
will improve significantly with much milder daytime temperatures,
but nights will remain chilly as clearing skies/light wind
combine to bring ideal cooling with lows dropping well into the
40s.

Sunday through next Wednesday night...mid/upper level ridging will
increase over the ArkLaMiss region supporting warmer temperatures
and continued mostly dry weather through early week, but there are
indications that a slow-moving shortwave trough crossing the
Southern Plains may eventually increase rain chances over the
ArkLaMiss by the time we get to Wednesday and Wed night. /EC/
