The episode as NWS JAN wrote it up.
Scattered afternoon thunderstorms developed across portions of Mississippi on August 7th and 8th. A few of these storms were severe and produced damaging wind gusts.

Area Forecast Discussion
National Weather Service Jackson MS
246 PM CDT Sun Aug 7 2022
.DISCUSSION...
Tonight through Tomorrow:
Our area remains under the influence of upper level ridging with 500
mb anomalies 2-3 dam above climate normals. While the heat and
humidity isn't as oppressive as we dealt with earlier this summer,
it doesn't require temperatures to be much above normal to result in
heat indices near or above heat advisory criteria in August. The
subtropical Bermuda high will remain in tact through the short term
period which will allow light southerlies to maintain high
humidities through Monday.
Tonight, isolated showers will diminish early, leaving partly cloudy
skies. The best cloud coverage will likely remain in the east where
more substantial convective debris cirrus may linger. We fall into
the 70s F overnight for lows with winds light and out of the south.
Monday, we warm quickly and with slightly higher mid level heights
temperatures likely run up 1-3 F higher than we saw today. With
observations in some of the MS Delta areas reaching near 103-105 F
for heat indices (HI) today, and with little change in boundary
layer moisture expected, this should result in a corridor of 105-110
F HI for areas of the Delta along and north of the I-20 corridor.
For this reason, a heat advisory is required in those areas during
the peak heating hours of 10 am until 6 pm Monday.
Satellite water vapor imagery depicts a broad, weak upper trough
extending from the southwestern Atlantic near 75W and cutting across
to the west across the Florida Peninsula. This feature is forecast
by guidance to be somewhat disrupted and resulting in a stretched
out zone of vorticity. The southwestern flank of this troughing is
expected to detach and drift west through Monday into the northern
Gulf. This feature may provide impetus for storms to be a bit more
vigorous late day Monday as they move roughly southeast to
northwest. With the slightly improved boundary layer thermodynamics
and the resulting marginal drops in upper heights by late afternoon,
this may result in a zone of increasing instability and lift. While
severe weather is not anticipated with synoptic velocities below 25
kts through the column, propagating thunderstorms along surging
outflows encountering SBCAPE >3,500 J/KG may produce an isolated
damaging wind gust or two. /86/
Tuesday through Sunday:
The forecast through next weekend still looks like summer across the
CONUS. An upper-level ridge should remain centered over the High
Plains, while an upper trough sits over the eastern CONUS. Latest
trend in guidance has been for a deeper trough by late week/weekend.
Shortwaves moving through the flow aloft will provide some
enhancement to rain chances at times, but most POPs will be driven
by daytime heating and will peak during the afternoon hours. A cold
front does look to drop into the broader Gulf Coast region by around
Thursday, and this would usher in some drier air to at least
northern parts of our forecast area depending on how far south it
pushes. Following the trend in guidance regarding the depth of the
eastern CONUS trough, POPs were shifted to focus mainly along the
Gulf Coast Friday through the weekend. Moisture will pool ahead of
the front, and could result in more focused chances for heavier rain
along and south of the front as we head into the mid/late week
period.
As far as heat is concerned, it's not out of the question for parts
of the Delta to still see heat index values up to around 105 on
Tuesday, but decreasing heights aloft and increasing rain chances
for those areas will limit any threat for dangerous heat. At least a
few days of precip and upper-level trough influences will keep heat
out of the Hazardous Weather Outlook for most days this week. /NF/

.AVIATION...
18Z TAF discussion:
Isolated to scattered SHRA/TSRA are possible this afternoon into
evening with the best chances for southern and eastern sites.
SHRA/TSRA chances diminish after 00Z. Some patchy fog is possible
for PIB/HBG between 10Z and 13Z Monday morning with minimal
impacts to CIGS/VSBY expected. VFR conditions with a southerly
wind generally under 10 kt will otherwise prevail.
