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 Feb 5, 4:18 PM CST, 23 minutes earlier.

Area forecast discussion, Feb 5, 4:18 PM CST, 23 minutes before
Area Forecast Discussion
National Weather Service Jackson MS
418 PM CST Wed Feb 5 2020

...SEVERE WEATHER LIKELY AND FLASH FLOODING REMAINS POSSIBLE THROUGH
TONIGHT...

.DISCUSSION...

Prior relevant morning discussion through this afternoon-evening:

An active weather day is on tap today & will bring severe weather
& flash flooding potential across the region. Severe weather,
including tornadoes & some possibly strong, is likely & some flash
flooding is possible.

Rest of today: This morning the mid-level ridge axis is centered
over the Caribbean Islands, leading to a an influx of sufficient
low- level southerly return flow of warmth & moisture. Surface
analysis this morning indicates a surface low & baroclinic zone
across the ArklaMiss Delta, ArkLaTex to mid-South & will only
deepen through the afternoon, while cooler conditions exist in the
wake of the boundary in the northwest Delta. The synoptic pattern
consists of a longwave amplification with the spoke of energy &
jet streak energy through southern Plains & northern Mexico. This
will continue to swing out along the base of the trough & eject
northeast across the ArkLaMiss region. In conjunction with low-
level deepening & surface cyclogenesis, strong reflection in the
low-level wind field response will occur. Morning sounding
analysis shows near the high end or climatological maximum in low-
level observed destabilization (i.e. LCH surface based CAPE ~2500
J/kg & JAN surface/mix-layer CAPE around 800-1000 J/kg). This
juxtaposition of steep mid-level lapse rates & strong mid-deep
layer shear (i.e. 6.5 deg C/km lapse rates @ 700-500mb & 40-70kts+
effective bulk shear @ 0-3km & 0-6km, respectively) continue to
support higher end severe weather potential.

This low-level feed of high Theta E is leading convection
development across areas in south-central to western Louisiana is
serving as the impetus for convective development. This will
continue to spread to the east-northeast across the region, with
hi-res CAM guidance indicative of storms along the northern
gradient of the significant tornado parameter gradient (STP).
Local HRRR guidance is definitely showing the potential for some
1500-2000+ J/kg surface based CAPE along & southeast of that
frontal & baroclinic zone & storms potentially riding along &
southeast of that boundary. SPC mesoanalysis & forecast indicate
nearly 2-3 STP along the Natchez Trace Corridor & especially from
near Winnsboro up towards Columbus & to the south. This area also
has pressure falls of 3-6mb as the surface low deepens. Hi-res
CAM guidance continues to paint area in this vicinity with the
highest potential for tornadoes, including some possibly strong.
Exact storm mode may be somewhat of a question, per some other
local CAM guidance, but there will be some potential for higher-end
severe weather. This environment is anomalously destabilized &
sheared. In conjunction with SPC, introduced an "Enhanced" severe
risk area from near Vicksburg to the Jackson Metro & to the
northeast to including near Grenada to the Golden Triangle. For
now, all modes of severe weather are possible. Due to the strong
clockwise curving hodographs, tornadoes are likely & some possibly
strong. Damaging winds up to 70mph & large hail of up to golf
ball size are also possible. These will be reflected in the
HWO/graphics.

In addition, the flash flooding potential remains across the area
as there will be high moisture in conjunction with a deepening
synoptic jet, upper diffluence along the low & also any convective
potential. In conjunction with anomalous deep layer moisture &
very wet antecedent conditions, especially from any heavy rain
this morning, will keep potential around. Due to that, rainfall
of 1-3 inches, with locally higher amounts, is possible across the
region. Local hi-res CAM guidance & HREF suite continues to
support this. No flash flood watch is needed for now as this
mesoscale driven & some details are not as clear. Kept the
HWO/graphics the same as before.

Lastly, due to a strong developing pressure gradient some gusts
upward of 25-30mph can't be ruled out. Expect these winds to really
ramp up into the afternoon as the surface low rapidly deepens &
moves through the Delta. For now, winds don't seem to ramp up
enough for a wind advisory or mention in the HWO/graphics. /DC/

Tonight into Thursday:

Tonight: As the longwave trough digs into southern Texas &
northern Mexico, this will continue strong ascent, low-level
surface pressure response (i.e. rapid deepening & cyclogenesis
with surface low around or less than 1000mb) & feedback in the
broad scale deep layer jet streak response. The upper level jet
will rapidly deepen to nearly 100-150kts @ 300-500mb. Expect the
severe potential to continue shift to the east-northeast, but
severe potential could remain near or a few hours after midnight,
especially for eastern-southeast Mississippi, especially on the
eastern half of the Highway 84 corridor & Interstate 59-Highway 45
corridors. All modes of severe weather, including tornadoes,
damaging winds & large hail, remain possible as well, but higher
end severe weather becomes less likely than earlier in the
afternoon-evening. In addition, this low pressure will continue
to feed high Theta E air (i.e. ~330-335K 850mb Theta E) over
mainly for areas along & southeast of the Natchez Trace. This will
coincide with increasing ascent aloft for areas along & to the
southeast. Due to that, some flash flooding potential will remain
into the overnight hours. As of now it is difficult to pin down
exactly areas of best rainfall totals, but most hi-res CAM
guidance indicate potential for some localized 1-3 inches, with
localized higher amounts, especially including rainfall totals
through this evening. For now, will keep the graphic/HWO going as
is & no flash flood watch for now.

Thursday: Expect rapid drop in deep layer moisture (i.e. PWs
falling from around an inch & a half to a half inch) in the wake
of the cold front as strong northwest flow aloft & broad scale
subsidence move. This will help rain chances to quickly clear out
from the northwest through the afternoon. The highest rain chances
will be near daybreak southeast of the Natchez Trace & continue
to drift off to the southeast through the day. Expect a blustery
afternoon as cold advection will keep low clouds & much cooler
than normal high temperatures. Temperatures will struggle to reach
the upper 40s in the Delta while highs will still only peak in the
mid-upper 50s in the Pine Belt, Interstate 59 corridor & east
Mississippi. /DC/

Thursday night through next Wednesday:

Going into Thursday night, some precip will linger as moisture wraps
around the backside of the exiting trough. With the cooler airmass
moving in at that time, temperatures will drop into the 30s with
some spots dropping to freezing in the north-northeastern part of
the CWA. There is a chance that some of the lingering light rainfall
after midnight could transition into light snow/flurries between
midnight and sunrise, before the precip exits off to the east. No
impacts are expected from the snowfall should it occur though. A lot
of this will depend on how far the temperatures will fall in the
northeastern CWA before the precip moves out. The cloud cover could
inhibit the fall of temperatures so that the precip just remains as
light rainfall. We'll continue to watch this combination in future
model runs.

After the precip exits, Friday will be dry with seasonally normal
temperatures as winds rotate out of the south again. Highs will be
in the 50s areawide. By Saturday, a weak boundary swings around the
base of an upper shortwave and triggers some light and scattered
showers over our area. The global models vary on the strength of
this boundary and the moisture availability so that some models do
not show any rainfall over the area. At this time, it was decided to
at least include some slight chances for rainfall. Again, we'll see
how the models react with future runs.

The weak boundary will dissipate by Sunday and will leave Sunday
warm and dry with highs increasing into the mid to upper 60s. Rain
chances will be on the increase again though going into Sunday night
and Monday as an upper shortwave trough dives down out of the Upper
Plains. An accompanying frontal boundary will move through the CWA
on Monday. With the good warm air advection ahead of the boundary
and plenty of Gulf moisture available, some convective storms will
be possible. This could lead to some heavy rainfall and possibly
flash flooding. As the boundary lingers over the area through
Tuesday, this certainly elevates the concern for heavy rain and
flooding. With so much uncertainty in the models in the nearer term
though , we'll hold off on any mention of this in the HWO for now.
Another rainy system looks to move through in the second half of
next week, so it's likely we'll see some flooding at some point next
week. Stay tuned for future updates concerning next week. /10/

&&

.AVIATION...
18Z TAF discussion:
A mix of flight conditions will exist throughout today as a
frontal boundary and severe weather affects the region. The front
has already passed through GLH and GWO so that winds are from the
north- northwest now. As the front passes through this afternoon,
southerly winds at the rest of the TAF sites will rotate to a
northerly direction as well. Expect ceilings to drop universally
throughout the afternoon to IFR as scattered to numerous storms
ramp up and move across the region from southwest to northeast.
The severe storms will wane by 06Z with showers lingering through
much of Thursday. This will keep ceilings and visibilities low
through at least 18Z tomorrow. /10/
