What forecasters said that day

The local office's own words before this wind advisory 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 wind advisory went out at Aug 26, 11:51 PM CDT, 5 hours 8 minutes earlier.

Area forecast discussion, Aug 26, 11:51 PM CDT, 5 hours 8 minutes before
Area Forecast Discussion
National Weather Service Jackson MS
1151 PM CDT Wed Aug 26 2020

...Threat for Impacts from Hurricane Laura Increasing for the
ArkLaMiss...

.UPDATE...
Updated for evening discussion.

&&

.DISCUSSION...

Extremely dangerous Hurricane Laura is close to making landfall in
extreme southwest Louisiana, and it is still forecast to move
northward across western LA before making a northeast turn as it
reaches Arkansas. Based on the increased tropical storm force wind
probs from NHC in western portions of the area, have added Ashley
County and Morehouse Parish to the Tropical Storm Warning. Expect
the wind and tornado threat to increase considerably as we
approach daybreak over southwest portions of the forecast area.
Given that some of the latest NWP guidance has shifted slightly to
the east over northern Louisiana, confidence in wind, tornado,
and heavy rain threats has increased for along/west of the MS
River, and it wouldn't be surprising if a few more
counties/parishes need to be added to the TS warning. /EC/

Prior discussion below:

Tonight through Thursday night: Regional radars at mid afternoon
had a band associated with Hurricane Laura tracking west across
southern Louisiana and scattered storms across central
Mississippi. The band across southern Louisiana may bring strong
gusty winds to our southwest most zones this evening while the
activity across central Mississippi should dissipate. The main
threats associated with Hurricane Laura are still expected to
begin impacting our southwestern most zones early Thursday morning
as Laura moves inland. The latest official advisory had Laura
making landfall tonight as a strong hurricane near the Upper Texas
and northwest Louisiana coast. The center of Laura is then
forecast to move over northwestern Louisiana Thursday and across
Arkansas Thursday night. This will bring a threat of tornadoes,
damaging wind gusts and heavy rainfall to at least the western
half of the ArkLaMiss early Thursday morning through Thursday
night. The rain bands associated with Laura will bring a threat of
tornadoes and damaging wind gusts mainly to the area along and
west of the Interstate 55 corridor especially during the day
Thursday. Sustained winds of 30-40mph with gusts of 50 mph is
possible over our western most zones early Thursday into Thursday
evening with lighter winds and gusts further east into
Mississippi. Tropical Storm Warning remains in effect through
Thursday evening for Catahoula, Concordia, Franklin, and Richland
Parish. Heavy rain is expected especially where convective rain
bands set up Thursday. Two to four inches of rain in a short
amount of time will bring the potential for flash flooding
especially in low lying and urban areas over the western half of
the CWA early Thursday and Thursday night. /22/

Friday through Wednesday: The forecast period starts off Friday
morning with ongoing showers and storms as the remnants of
Hurricane Laura lift northeast through north central Arkansas. Any
impacts to the area are expected to diminish through the day as
Laura lifts away to the north of the CWA. Locally heavy rainfall
can't be ruled out though, especially if any training materializes
within trailing convergent bands. The tornado threat will also be
decreasing as the strongest wind fields become displaced to the
north and low-level flow veers. This will result in nearly
unidirectional southwest flow with low values of 0- 1km storm
relative helicity owing to little area swept out in respective
hodographs. The resulting lack of available horizontal streamwise
vorticity will preclude a lingering tornado threat through the day
Friday.

What's left of Laura will get absorbed into northern stream flow
Friday into Saturday morning as a shortwave trough drops into the
Great Lakes region. Deep tropical moisture will remain in place
across the region, however, with PWATs of 2-2.25" through the
weekend and into next week. This will support scattered to numerous
diurnally driven showers and storms each day. Dangerous heat could
become a concern over the weekend as warming temperatures combined
with tropical moisture yields heat index values near 105 degrees,
but confidence remains low at this time owing to potential storm
coverage. Model guidance begins to diverge heading into the middle
of next week as the GFS depicts an amplified trough swinging through
the Mississippi Valley with an associated strong cold front
encroaching on northern Arkansas. The ECMWF, on the other hand, has
stronger subtropical ridging over the southeast states and deflects
a weaker shortwave trough to the north. More model guidance
consistency will be needed before confidence on any cold frontal
passage, or lack thereof, increases. /TW/

&&

.AVIATION...
00Z TAF discussion:
Scattered TSRA/SHRA were noted on radar GLH-GWO-MEI AT 23Z. This
activity will move north of the area by 02Z. Elsewhere, VFR
conditions wl prevail through 08Z Thursday. After 08Z Thursday
MVFR cigs are expected to develop from the southwest associated
with hurricane Laura. MVFR cigs are expected to prevail through
17Z before improving. Gusty winds to 30 knots are also expected to
develop over the western half of the area as Hurricane Laura
tracks inland to our west Thursday and Thursday night. /22/
