Several clusters of storms developed across central Mississippi on the evening of July 21st. These storms evolved into two loosely organized line segments that produced wind damage across the area.

The episode as NWS JAN wrote it up.
Several clusters of storms developed across central Mississippi on the evening of July 21st. These storms evolved into two loosely organized line segments that produced wind damage across the area. Numerous trees were blown down along with several power lines.
The local office's own words before the first event, 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 the first event at Jul 21, 5:40 PM CST, 1 hour 8 minutes earlier.

...DANGEROUSLY HIGH HEAT AND HUMIDITY TODAY...

.AVIATION...
00Z TAF discussion:
Showers and thunderstorms will continue to develop across the
Highway 82 corridor late this afternoon with VCTS at GLH/GWO/GTR.
This activity is expected to push south through the evening hours
eventually impacting most terminals. Some of these storms may also
be severe with 50kt or greater wind gusts and small hail. Timing
and evolution of the storms has been difficult to pin down and
amendments to the TAFs are likely through the evening as storms
evolve. An additional round of showers and storms may redevelop
along and south of I-20 mid to late tomorrow morning, but will
depend on how storms evolve tonight, so did not mention in the TAF
at this time. /TW/

.DISCUSSION...Not much has changed from earlier thinking
concerning both Excessive Heat and severe storm potential for
the rest of today into this evening. What has changed is the
concern for heat on Friday.
Heat concerns...It's Hot/Humid out there for sure with heat indices
(HIs) peaking across the warning area between 110-117 degrees. So
the upgrade to the Excessive Heat Warning is working out and in the
locations noted. The rest of the area is reaching HIs of 105-110 so
the Advisory area is working out. This oppressive heat will linger
into the evening and will allow these heat products to expire at 9pm.
As for Friday's heat potential, much of this will hinge on storm
evolution this evening and how that "uses" up the boundary layer
moisture. Typically it has a sizable impact on the following day.
The result is lower temperatures and dew points which keeps HIs in
check. In this situation, the latest NBM guidance actually picks
this up nicely and does lower both temps and RH. Even with a
lowering of those elements, much of the area will still see
hot/humid conditions supporting Heat Adv criteria. So, have added an
Adv for Friday which covers like 2/3rds of the W/NW forecast area.
The SE 1/3 will be left out.
Storms and severe weather potential...earlier discussion and
thoughts are on track. Cap is holding and the more subtle s/w to
help trigger convection is still off to our NW/N over AR. So while
we noted multiple favorable parameters earlier, there are
limitations which could keep convection held in check. First is the
subtle s/w which may not provide enough deep ascent. The other is
the cap being a bit stronger and warmer 700mb temps. Despite having
solid low level convergence and moisture pooling near the boundary
across the MS Delta, those limitations could be just enough to slow
vertical motions. Overall, it's a mixed bag with how the models
handle things. Still, the environment in place is very unstable with
SBcape peaking at 6000-6500 j/kg off the SPC meso-a site and several
other key parameters very supportive of severe storms all in place.
From this, will lean on the more aggressive guidance with more
active convection later this evening. Timing is basically the same
with initiation more in the 5-7pm range and storm evolution from 7pm
to midnight or 1am. While close to prev noted times, there's still
some differences and a slightly later trend. Due to this, will
adjust the graphics to better reflect latest thoughts.
Other weather elements...PoPs were increased tonight across the
central part of the forecast area (mainly where the Slight risk is
situated) as guidances seem to be underdone. On Friday, NBM PoPs
were quite high in the SE and opted to lower values some. This is
based off the overall thinking tonight will offer greater coverage
of storms which will impact moisture return on Friday and ultimately
cause lower precip potential during that period. /CME/
Friday night through next Thursday...
Another hot and humid weekend is on tap for the region from the
influence of 700mb anticyclonic motion, which will keep a warm,
southerly airmass persistent at the surface. Precipitation chances
will be mostly confined to the E/SE portions of the area, but will
remain isolated to scattered in the afternoon hours on Saturday and
Sunday. By Monday through the new work week, surface heights will
begin to build over southeast CONUS. Increased chances of dangerous
heat will present itself again, with the potential of heat indices
ranging 110-115 degrees in the northwest, especially the Mississippi
Delta through mid-week. An Significant for heat stress has been put
into the HWO for the Mississippi Delta region, while an Elevated is
outlooked for the remainder of the CWA on Saturday and Sunday.
Rain chances will remain diurnal in nature, with higher chances of
isolated to scattered showers and storms being in the south and
eastern portions of Mississippi. High temperatures will continue to
range in the middle to upper 90s, while overnight lows will
primarily be in the 70s. Continue to stay hydrated and limit
outdoor activities throughout the day! /AJ/
