What forecasters said that day

The local office's own words before this tornado 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 tornado warning went out at Apr 19, 6:58 PM CDT, 46 minutes earlier.

Area forecast discussion, Apr 19, 6:58 PM CDT, 46 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
658 PM CDT Sun Apr 19 2020

...SEVERE STORMS REMAIN LIKELY ACROSS MUCH OF THE ARKLAMISS THROUGH
TONIGHT...

.UPDATE...
Updated for 00Z aviation discussion

&&

.AVIATION...
00Z TAF discussion:
Numerous TSRA were observed at 2330Z south of I-20 while RA was
observed north of I-20. This was leading to a mix of IFR and LIFR
conditions across the area. Although the rain and thunderstorms
will move east of the area after midnight as a cold front moves
through, IFR cigs will continue to prevail through 15Z before
gradually improving to VFR into the afternoon. VFR conditions are
expected areawide by 20z. /22/

&&

.DISCUSSION...
Tonight through Saturday...The threat for severe weather and flash
flooding will be ongoing across a good portion of the forecast area
for the remainder of this afternoon and into the first half of the
tonight period.  Thus, a "Tornado Watch" remains in effect until 7
PM and a "Flash Flood Watch" in effect until 1 AM Monday. As an
upper level trough drives a strong cold front east through the
region from late this afternoon into tonight, ample instability
(particularly across locales along and south of the Interstate 20
corridor), coupled with strong wind shear, and steep mid-level lapse
rates will maintain this threat into tonight.

Damaging wind gusts, large hail, and tornadoes will remain possible
during this time. Additionally, torrential downpours from storms
training across the same locations, will result in localized flash
flooding across portions of the area, along with an increased threat
of river flooding.  Some light showers will linger behind the front
a couple of hours past midnight, but as the overnight hours progress
activity will exit east and out of the forecast area, with high
pressure building in from the west.

Quiet weather, along with slightly cooler drier conditions, will
exist across the region Monday into Tuesday.  The high will slide
further east of the region on Wednesday resulting in a return in
southerly flow.  This, as the pressure gradient tightens over the
region in response to a deepening and developing storm system
approaching from the west, will cause increased moisture return
across the CWA through Wednesday night.

Currently, it's during this Wednesday afternoon through Thursday
timeframe, that perhaps another bout of severe weather may be
possible across the forecast area, along with perhaps some heavy
rain potential.  Currently, models continue to differ in their exact
track and timing of this system. Therefore, confidence in
introducing a threat of severe weather into the HWO currently
remains too low.

Showers and storms currently look to exit the region through the
course of Thursday.  High pressure again builds into the region from
the west.  At a minimum, the first half of Friday looks to remain
quiet.  However, rain chances could again be on the increase Friday
night into Saturday as another system potentially swings east into
the region. /19/
