The episode as NWS JAN wrote it up.
The remnants of Tropical Storm Cristobal moved north across the region. The tight pressure gradient associated with this tropical system produced gusty winds. This resulted in a few downed trees across portions of Central Mississippi.

Area Forecast Discussion
National Weather Service Jackson MS
513 AM CDT Mon Jun 8 2020
.DISCUSSION...
Today into tonight:
As of 4am, Cristobal's center was located just southeast of
Natchez and has been downgraded to a tropical depression. The
forecast track continues to take Cristobal north generally along
the Mississippi River and into eastern Arkansas. This will be
occurring as a potent shortwave trough swings through the Four
Corners region and into the Central Plains. While the intensity
has been lowered, impacts are still expected across the Lower
Mississippi River Valley today into tonight.
Flooding threat:
A broad precipitation shield was located generally along and north
of I-20 early this morning and will continue to lift north through
the remainder of the morning hours. This area of rainfall is
removed from better instability to the southeast, thus rainfall
rates have been limited with only isolated flooding concerns. The
main flooding threat is expected to evolve mid to late morning and
lasting into the early evening hours across portions of central
and southern Mississippi. 00/06z suite of hi-res CAM guidance is
in general agreement that two trailing convergent bands of
convection will develop with one roughly along the I-55 corridor
and another roughly along the I-59 corridor. Surface based
instability will increase into the 1500-2000 J/kg range which will
support intense rainfall rates with these storms as they reside
within a moist tropical airmass characteristic of 2.25-2.5" PWATs.
4-8" of rain with locally higher amounts will be possible over a
short duration within these bands of training convection. A
significant threat for flash flooding was maintained in the
HWO/graphics and the area was expanded slightly.
Severe weather threat:
Strong low-level wind fields will continue to foster 30kts of
0-1km shear with 300 m2/s2 0-1km helicity across eastern
Mississippi. Increasing instability this morning through the
evening hours will result in a favorable parameter space for
damaging winds and tornadoes within trailing bands of convection. A
slight risk for severe weather will be maintained over eastern
Mississippi with a marginal risk further west to the Mississippi
River.
Gusty winds:
Several wind gusts in the 40-45mph range have been observed early
this morning and will continue through much of the day as a tight
pressure gradient remains in place. These winds will be capable of
downing scattered trees, especially given saturated soils. A wind
advisory and respective "elevated" threat area in the
HWO/graphics will remain in place through the day today.
Tuesday and Tuesday night:
The remnants of Cristobal will become absorbed into the
aforementioned trough as it lifts northeast into the Great Lakes
region. A strong cold front will also be pushing east through the
Great Plains and into the Lower Mississippi River Valley. A very
moist tropical airmass will remain in place across the region
ahead of the approaching front with scattered afternoon showers
and thunderstorms possible over far eastern portions of
Mississippi. High temperatures will surge back into the low to mid
90s beneath partly cloudy skies, which combined with tropical
moisture and mid 70s dewpoints will result in heat index values of
100-105 degrees. A limited threat area has been added to the
HWO/graphics given the anticipated hot and muggy conditions.
There's some signal that a line of storms could move into the area
Tuesday night ahead of the cold front, but timing and coverage
differences remain amongst model guidance so will keep the
HWO/graphics clear of any additional severe threat for now. /TW/
Wednesday through Sunday:
Depending on the exact timing of the
front, convection may linger into the daytime on Wednesday. While
guidance is indicating moderate instability ahead of the front, deep
layer shear for convective organization will be relatively weak and
morning timing casts a severe weather threat into doubt. Most
guidance suggests rain will exit the region by sunset. A noticeably
cooler and drier airmass will follow the front with dewpoints
dipping into the 50s. It's also quite possible lows will dip into
the upper 50s in a few spots both Thursday and Friday morning in the
wake of the front. Surface ridging will build in through the end of
the week as a mid/upper trough shift east toward the Atlantic coast
and upper ridging builds over the western. The GFS is hinting at the
upper trough lingering back closer to our area a bit longer with
another front developing and sliding into the area from the north
Friday night into Saturday. For now this appears to be an outlying
solution, so we'll keep rain out of the forecast during this time
frame for the time being. /DL/

.AVIATION...
06Z TAF discussion:
Forecast centering around the northward progression of TS
Cristobal. A few VFR obs to the north...most have already flipped
to MVFR as the storm bands move across the region. Forecast is
largely an MVFR one... some IFR drops with cigs and vis closer to
the center of the storm. Winds from easterly to southerly by the
end of the TAF pd. Rain chances throughout, have left vcts in the
afternoon time frame with the better chances to deepen convection.
Expect gusty winds 25-30 kts... some higher possible gusts
tomorrow afternoon/evening.
