Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 23 minutes after it went out.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

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 19, 12:16 PM CDT, 1 hour 52 minutes earlier.

Area forecast discussion, Apr 19, 12:16 PM CDT, 1 hour 52 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
1216 PM CDT Sun Apr 19 2020

.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion: While IFR/MVFR conditions will improve to VFR
at most locations this afternoon, areas between GLH, GWO and GTR
will remain in those conditions through much of the period.
Scattered to numerous showers and thunderstorms will eventually
overspread the area from the west this afternoon with
deteriorating conditions as they do so. IFR/LIFR conditions with
gusty winds can be expected as storms impact each TAF site. The
rain and thunderstorms will move east of the area after midnight
as a cold front moves through, but ceilings will remain IFR
through the remainder of the period./GG/

&&

.DISCUSSION...
Quasi-stationary frontal boundary continues to oscillate
along I20 from northeast LA eastward through central MS. To the
north, elevated parcels with CAPEs around 2000 J/kg continue to be
isentropically lifted resulting in scattered to numerous showers
and thunderstorms. Immediately along the front, light showers and
fog persists. While to the south in the warm sector, widespread
stratus was seen in the satellite imagery, although some breaks
were beginning to occur. RAP data confirming the ascent/theta-e
advection over northeast portions with ongoing convection and over
east TX where new intense convection has developed. While the
latest CAM guidance continues to vary in the scenario this
afternoon, they all do agree that modes will be mixed through the
afternoon and evening as the event plays out. Made some changes to
weather and PoP based on latest trends and thinking. Expect
intense storms in the warm sector this afternoon as the boundary
layer warms with clusters of supercells producing very large hail,
damaging winds and tornadoes, some strong. Also, adjusted temps a
bit, mainly in the north where ongoing precipitation will keep
temperatures cooler./GG/

Prior discussion below:

Today and tonight...
A warm front is slowly lifting through the Gulf States this morning,
providing an increase in rich moisture and warmer temperatures in
the boundary layer, setting up for the severe weather anticipated
today. Overnight and this morning, general ascent across the region
invof and isentropic upglide over the frontal boundary in concert
with steep mid level lapse rates contributed to the development of
some severe elevated convection as well as some more widespread
showers and thunderstorms.  Much of the convection has shifted
north, and though some scattered activity will remain possible
through the morning hours, models are rather consistent with a
broader area of intense convection developing after 18z.

Previous model runs have been a little inconsistent with the
projection of timing, as well as modality for the storm development
this afternoon.  Expecting some version of a wind and hail threat
with some linear segments...but has transitioned into a concern this
afternoon for supercell development as well. An expanding warm
sector will develop as the warm front lifts through the region.
Interaction with the frontal boundary could increase tornadic
potential with early storms, though the main concern initially will
be damaging wind and hail. The situation changes with time however.
Previous model runs have had some issue with whether or not the
morning scattered convection precludes restratifying the column. But
the more recent runs have developed convection just to the west
ahead of a deepening upper trof, moving into far more unstable air
over the region. SBCAPE values in excess of 3000J/kg in the
afternoon ahead of the developing convection in the HRRR 07Z run.
HREF mean sb CAPE is in the same range, more or less, as well as the
RAP, etc. Deep shear of 50-60kts would signal the strong potential
for convection this afternoon to be supercell oriented, and the scp
as well as sig tor parameters all show the same trend. Main threat
will be wind and hail with early scattered convection...but the
afternoon potential for supercells will add in the concern for
tornadoes, potentially strong and long tracked particularly to the
southeast. Given the dynamic set up aloft in concert with 1.5-2" PWs
across the area of most intense convective potential, a flash
flooding concern is added to the mix. Expected rainfall totals range
from 1-4 inches, with a 2.5-4" max axis along and near I-20 across
Mississippi. /HJS/

Monday through Saturday night...
Surface high pressure ridging will build across the area on
Monday. A nice day is on tap with highs mostly in the 70s across
the area. The nice weather will continue on Tuesday as high
pressure ridging continues from a high centered over Missouri. The
surface high will move eastward into the Ohio Valley Tuesday
night into Wednesday, and the surface flow will swing around to
the east then southeast by Wednesday afternoon. A deepening storms
system will approach the region Wednesday, with increasing
chances for storms in the west.

Thunderstorms will spreads east across the area Wednesday evening
through the overnight hours. There are some differences between the
GFS/ECMWF, but they are in fairly good agreement of the timing of
this system across the region. Both of them indicate good
instability and strong shear during the overnight hours, so another
round of severs storms look possible. SPC has not introduced a
severe outlook for this period, but may in future outlooks. Showers
and storms will continue through Thursday morning, but will end from
west to east during the afternoon hours.

High pressure will once again build across the region on Friday, but
this crazy April pattern may rear its ugly head again on Saturday,
as both the GFS/ECMWF move another strong storm system across the
region./15/
