The remnants of Hurricane Harvey moved across the ArkLaMiss region on August 30th and 31st and brought gusty winds and rain to the region. As Harvey decreased to a depression on the 31st, gusty winds still remained across portions of the region.

The episode as NWS JAN wrote it up.
The remnants of Hurricane Harvey moved across the ArkLaMiss region on August 30th and 31st and brought gusty winds and rain to the region. As Harvey decreased to a depression on the 31st, gusty winds still remained across portions of the region. This resulted in some downed trees outside of any shower activity. Locally heavy rainfall resulted in instances of flash flooding.

.AVIATION...
12Z TAF discussion:
Precipitation will increase through the morning hours as the
remnants of Harvey tracks across the northwest portion of the
region. Expect primarily MVFR flight cats at most areas through
this evening, although there will be pockets of VFR flight cats
(and also IFR cats) with an expectation of a gradual improvement
toward VFR conditions later tonight, at least in the southwestern
half of zones. Winds will be strong and gusty today (up to 35 mph
in gusts) in most areas through the period, primarily from a
southerly direction, with some dissipation of winds anticipated
tomorrow evening (especially in southern zones). Directions will
at least briefly switch over to the north today at GLH/GWO on the
northwest side of Harvey's circulation. Otherwise, the most
concentrated rainfall will be through midday at GLH/GWO but
widespread showers are expected elsewhere. In addition, some
potent storms should form around GTR/CBM/NMM/MEI around midday
through mid afternoon with the prospect of any storms through the
afternoon much more questionable at HKS/JAN/PIB/HBG. /BB/

.DISCUSSION...
Through Tonight:
The center of the remnants of Harvey are poised to track northeast
into the Arklamiss Delta through the morning hours and then clear
entirely north of our region sometime this evening. Thus far
overall rainfall amounts in our region in association with Harvey
have thankfully been lighter than anticipated and no major
flooding issues have been reported. But we still have one more day
to get through before the departure of Harvey starts removing
threats of hazardous weather for the entire forecast area rapidly
this evening.
Overnight precipitation has been pretty sparse at times as the
pronounced dry slot aloft on the eastern side of the Harvey's
circulation has put a decent lid on shower production. However,
over the past hour or two, precipitation has been gradually
increasing from west to east as the center of Harvey approaches
and shifts the dry slot slowly east. Moderate to locally heavy
showers with efficient (high) rainfall rates are expected to
develop over mainly the Arklamiss Delta counties and parishes
through the day and the previous flash flood watch was altered a
bit to align better with the axis where some eventual flooding
issues are more likely. East of the track of the low there is
again expected to be increasing showers (and even thunderstorms)
through the morning hours as insolation provides enough
instability to trigger convection in the dry slot. Like yesterday,
some severe weather will be possible with storms that develop in
the dry slot through the afternoon, but the risk will
predominantly be confined to eastern zones of MS. Isolated
tornadoes cannot be ruled out in any of the latter areas but
chances will be a little greater up near the Golden Triangle where
low level shear should be maximized. Like yesterday, we are not
fortunately not expecting enough atmospheric ingredients to worry
about strong (EF2+) and/or long-lasting tornadoes. The graphics
and HWO will be updated to reflect slight alterations in Flooding
and Severe threats.
As mentioned, precipitation should be gradually diminishing from
southwest to northeast tonight as the center of Harvey begins
pulling away. The occasionally gusty winds in all areas during the
day should become increasingly confined along and north of Highway
82 during the evening. Any lingering storms over eastern MS
should be exiting by mid evening. Some clearing is possible from
the southwest late in the night and lows by dawn Friday should be
in the not-terribly-bad mid to upper 60s. /BB/
Friday through Sunday: As the remnants of Harvey pull away from the
region, the cyclone will pull notably drier air into our area just
in time for the weekend. This can be seen clearly in model 700 mb RH
fields (20-30C Td depressions) and progged PW (dropping to around an
inch). Meanwhile at the surface, dewpoints will remain down in the
60s to near 70 throughout the weekend. Beyond a lingering threat for
isolated storms over parts of E MS on Friday as the upper trough
axis passes overhead, no rain is in the forecast for the remainder
of the weekend.
Next week: Southerly low level flow will return by Monday, with
moisture returning through the day as well. This will bring a chance
for storms back into the southern portion of the area by the
afternoon/evening. An upper trough will deepen over the eastern
portion of the CONUS, bringing higher rain/storm chances across the
entire area as a solid cold front moves through Tuesday into
Wednesday. Behind the front, another intrusion of drier air is
anticipated with dewpoints dipping into the 50s and temps possibly
following suit Wednesday night. A little taste of fall as we head
into football season. /DL/
