What happened

The episode as NWS JAN wrote it up.

A cold front was stalled across southern Mississippi and a moist airmass was in place. This, along with daytime heating, allowed for storms to develop in the afternoon. Some of these storms were strong to severe.

Area forecast discussion, Sep 11, 9:59 AM CST, 3 hours 19 minutes before

Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
1059 AM CDT SUN SEP 11 2016

.UPDATE...Adjusted short term forecast fields based on current
observational trends, including low and mid cloud coverage over
northwestern half of the CWA this morning. Scattered to numerous
showers and thunderstorms still expected south of Interstate 20 this
afternoon and evening, with the best chances being focused along and
south of the Highway 84 corridor. The remains of yesterday's front
have stalled near the Gulf Coast and should serve as a focus for
convection. In the wake of the short wave trough passage yesterday -
and with a weak disturbance trailing along the Gulf Coast today - H5
temps have cooled by several degrees from yesterday. Resulting
steeper lapse rates will support a slight increase in potential for
damaging wind gusts with the strongest storms today./NF/

&&

.AVIATION...VFR conditions are expected to prevail areawide but
scattered SHRA/TSRA will develop during the afternoon especially
across the southern part of the area, primarily affecting KHBG/KPIB.
Some isolated showers/storms may affect KMEI/KJAN/KHKS but the
better rain chances will be along the Highway 84 corridor, which
would reduce categories to MVFR in heavier downpours. /28/

.PREV DISCUSSION... /issued 400 AM CDT SUN SEP 11 2016/

SHORT TERM...Today through Monday night...Early morning surface
analysis had a cold front just south of a Meridian to Natchez line
with a 1023mb high centered over Missouri. This front was nearly
stationary and local radars only had a few light showers along and
south of it at 330 am. Very little additional development is
expected until daytime heating kicks in. The driest air in the wake
of the front was limited to our northwest most zones with lower 60
degree dew points observed at Greenville and southeast Arkansas but,
lower 70 degree dew points were still observed south of a Greenwood
to Bastrop Louisiana line.  Early morning water vapor imagery/RAP
analysis a shortwave trough over the Great Lakes region extending
south across the Ohio valley. This shortwave trough will continue
east today leaving the cold front to stall across our south later
this morning. The surface high will shift east as well and nudge
drier air a little further across the Highway 82 corridor. This
drier air should limit convection today across our northern zones
but, storms will be possible across the remainder of our CWA. Cooler
than normal temperatures are expected for most locations today with
highs in the mid to upper 80s north of the stalled front. Monday the
surface high will shift east off the mid Atlantic coast resulting in
an east to southeast low level flow across our CWA. This will help
dissipate the stalled frontal boundary and allow moisture to spread
back into our northern zones. A greater coverage of mainly afternoon
and early evening convection is expected along with warmer afternoon
highs in the lower 90s at most sites. /22/

LONG TERM...Tuesday through Saturday...Our area will generally be
under surface and upper ridging as mostly zonal flow aloft will
prevail over the northeast CONUS. >1020mb surface high will be
departing off the Atlantic seaboard while more unsettled weather and
gradual longwave trough will extend over most of the northwest and
into the northern Rockies and into southern Canada. Guidance is in
pretty good agreement in split flow developing between the closed
upper low over the west and other trough further north. This will
only help promote continued ridging through mid-week. Euro ensembles
continue to show good probabilities of reaching or exceeding 20
degrees C at 850mb and the GFS ensembles still show some
probabilities of exceeding the 90th percentile around Wednesday to
Thursday timeframe. Went slightly above guidance/MOS for that time
period. This could bring mid-week temperatures near 3-5 degrees above
normal for this time of the year.

Rain and storm chances will prevail across the southern half of the
area most of the week. Moisture will be back on the increase with
any remnants of the boundary along the Gulf coast. PW's across most
areas could reach near an inch and three quarters, with better
moisture progged to move in later in the week. A weak and generally
disorganized low pressure over the central to northern Gulf of
Mexico will only bring back some increased moisture return in the
south as we go into Wednesday and Thursday as a plume of near 2 inch
PW's may move in. Expect afternoon showers and storms, with storm
chances in the southeast on Tuesday while best rain and storm
chances south of the I-20 corridor Wednesday into Thursday. As the
trough over Canada splits off from the west coast closed low, a cold
front will move east. Most of this will move through to our north
and east, but some wedging of slightly drier air could occur in the
northeast on Thursday. GFS shows some decent isentropic
descent/subsidence in northeast Mississippi which could help some in
limiting convective potential and dewpoints could be a touch lower.

As we go into Friday and into the weekend, the surface ridge will
shift over the Atlantic seaboard and upper ridging will gradually
move east while flattening over our area. This will help return flow
to develop, bringing in some of this better Gulf moisture, clouds
and storms back into the area. This will help us stay slightly
cooler, much closer to normal for this time for the year. Euro is
slightly more progressive with the closed upper while the GFS has
more phasing with a trough moving into southern Canada and the Great
Lakes. Regardless, return flow ahead of the cold front will bring
more abundant moisture back in from the northern Gulf, helping spark
much more widespread convection as we go into the weekend. /DC/
