.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion:
Low MVFR to IFR flight categories will linger through most of the
day due to Tropical Depression Gordon slowly drifting across the
region. Expect near IFR conditions to linger throughout the
afternoon with only brief increase to near MVFR conditions in
eastern TAF sites near GTR, MEI & PIB/HBG but that may be late in
the afternoon. Some showers & storms/VCTS are possible throughout
the afternoon but overall mostly rain showers with brief gusty
winds the afternoon. Any stronger shower or brief storm could
bring gusts up to or briefly higher than 30kts. Winds will remain
more east-northeast around 15-20kts or briefly higher in
northwestern TAF sites while more southeast in northeastern TAF
sites today. Elsewhere winds will remain more south-southeasterly
through the TAF period. Especially in northern sites, winds will
gradually turn more south-southeasterly into the evening & lighten
up somewhat. Expect the rain showers to lessen as we move into
the overnight hours, except up at northwestern TAF sites near the
center of the remnants of Gordon (i.e. GLH & GWO). Otherwise,
expect MVFR visibilities & IFR to possibly LIFR ceilings, due to
lowering stratus, to build in around 06/07-09Z. These low flight
categories will linger through mid-morning around 06/16Z. Some
more showers & scattered storms/VCTS can be expected again
tomorrow. /DC/

&&

.DISCUSSION...
Rest of today:

The center of circulation of Tropical Depression Gordon went
directly across the heart of the region, crossing right nearby
the Jackson metro & I-20 corridor early this morning. Overall
Gordon has rapidly weakened to a tropical depression with maximum
winds only around 30mph. Maximum winds have only gusted at most to
around 35mph this morning to maybe slightly higher in the Pine
Belt before gradually weakening. Due to the strong mid-level
ridge axis over the mid-Atlantic extending westward through the
mid-South & lower Mississippi Valley, the forward speed of Gordon
is quickly slowing. Expect a continued gradual weakening of the
winds into the afternoon but some maximum gusts upward of 25-30mph
aren't out of question. Due to the lower winds, removed the
"Limited" wind threat from the HWO & graphics. With some heavy
rainfall, couldn't rule out a couple of downed trees but overall
that threat is diminishing with time.

Main threats today continue to be the heavy rain & brief tornado
potential into the afternoon. 12Z morning sounding analyzed right
in the core of Gordon sampled ~2.4 inches of precipitable water,
which is a daily record. There has been a good core of dry slot
that has wrapped around the center of circulation & up into the
Golden Triangle & even up into the Highway 82 corridor. Due to the
slightly eastward track, rapid weakening & dry slot, overall
rainfall totals have been lower & mostly confined to the
convergent 850 & 925mb 340-345mb Theta E axis right along the
Mississippi & Alabama border, where much higher totals were likely
observed. Some areas in our Highway 45 to I-59 corridors have
likely received around 1-2 inches or so, especially along the
MS/AL state line. Due to the dry slot, this has overall limited
the westward scope of the band moving into the Golden Triangle.
Due to less rainfall potential up there, based on CAM & HREF prob.
matched mean guidance, only expanded the "Limited" threat for
flooding in the HWO/graphics into that area. The area in the Pine
Belt didn't receive as much rainfall & most HREF/CAM guidance
isn't really bullish on much redevelopment so the "Elevated" in
the HWO/graphics was removed & the Flash Flood Watch was
cancelled for that area. Elsewhere from around Jones up to Kemper
Counties & further northwest, the rainfall potential remains
possible. Expect increased moisture transport & low-level Theta-E
convergence on the back side of Gordon to our east, per SPC
mesoanalysis, to move westward into the heart of the region. This
combined with such anomalous moisture will result in potential for
high amounts, 2-4 inches & locally higher amounts. For now,
totals in the HWO & graphic look good, just scaled back the
southwestern extent of the "Elevated" area northeast towards the
updated Flash Flood Watch, left a "Limited" in the southeast due
to some possible redevelopment but less confidence, & expanded the
"Limited" northeast into the Golden Triangle due to some
possibility of some redevelopment. Expect this rainfall & flooding
potential to slowly shift northwest into the ArkLaMiss Delta as
Gordon slowly drifts west-northwest.

In addition, the potential for brief spin-up tornadoes continues
today as increased dry slot & low-mid level shear & helicity (i.e.
20-25kts 0-2 & 0-3km bulk shear & 100-150+ 0-1 & 0-3km storm
relative helicity) bring a favorable environment for tropical
tornadoes. Also can't rule out some brief damaging winds gusts
with any stronger rain band. This will continue to be the case in
any feeder bands that redevelop in central, north-central &
eastern Mississippi into the afternoon & late evening. As a
result, kept the "Marginal" mention for brief tornadoes from the
SPC in the HWO & graphics, but expanded it west-southwest towards
I-20 & the Mississippi River. There could be some potential for
some in the Highway 45 corridor as well but most CAM/HREF members
show potential a little closer towards & north of the I-20
corridor. This will continue to be possible into late evening
before midnight (i.e. ~10pm). /DC/

Prior discussion below:

Today and Tonight...Gordon officially made landfall late last night
at 22:15 CDT about 30 miles east of Biloxi Mississippi, as a strong,
70 mph, tropical storm.  Over the past few hours, the center of
Gordon has shown signs of tracking more northwest as it moves across
the Pine Belt region.  However, the system will continue to bring
gusty winds, possibly on the order of 30-35 mph gusts, to portions
of the forecast area through the course of today and into tonight.
These gusty winds could down trees, limbs, with some power outages
possible across the area as these could fall onto powerlines.  That
said, due to the rapid weakening of Gordon at landfall, in addition
to Gordon's center at landfall being well east of the Pine Belt, the
"Tropical Storm Warning" has been cancelled for Marion, Lamar, and
Forrest counties as sustained winds haven't met, and won't,
meet criteria.

The potential for heavy rain leading to some flash flooding will
persist across a good portion of the forecast area through the
period.  This potential won't just be confined to near the storm's
center.  North to south oriented bands of convection are expected to
develop during the late morning and afternoon hours south of the
storm's center, as heating and instability increase.  These bands
are expected to train across areas while producing moderate to heavy
downpours. These totals will add up pretty quick given the soupy
airmass residing in Gordon's wake, thus resulting in some localized
flash flooding.  Overall, rainfall totals in the three to six inch
range will be possible through at least early Thursday morning.

Another hazard that will be possible through the course of the
period, will be the potential for brief spin-up isolated tornadoes.
This will especially be the case in the aforementioned feeder bands.
With wind shear in abundance across the region, coupled with some
drier air aloft being wrapped into the storm, the development of
convection that'll be capable of producing isolated tornadoes. As a
result, a "Marginal Risk" for such activity exists across mainly
central and eastern portions of the CWA from this morning through
mid-evening.  While much of the wind and isolated tornado threat
currently looks to wane during the evening, the potential for
localized flash flooding will remain over mainly the Delta region
overnight into Thursday morning as Gordon weakens further. /19/

Thursday and Friday...The remnants of Gordon will continue to
lift slowly northwestward across Arkansas Thursday and Friday,
with a lingering low level convergence axis and plume of tropical
moisture trailing across our region on Thursday, then gradually
shifting westward into Friday. This will keep higher rain chances
around, especially from areas along and west of the MS River. Much
of the activity will be diurnally driven, so a lull is expected
during the overnight periods.

Some guidance suggests banding and potentially training heavy
rainfall will linger over SE Arkansas/upper Delta into the early
part of the day Thursday, so we opted to extend the duration of the
existing Flash Flood Watch for the far NW part of the area through
Thursday morning.

Saturday: The remnants of Gordon will be picked up by a shortwave
trough advancing eastward across the Mid Mississippi Valley and will
merge with an associated cold front extending from the Ohio Valley
into the Plains. Meanwhile, mid/upper ridging will temporarily build
over our area accompanied by a temporary decrease in deep layer
moisture especially for areas southeast of the Delta. Though we will
maintain isolated to scattered POPs mainly in the northwest,
convection should be more limited across most of the remainder of
the area.

Sunday through Tuesday: As the aforementioned trough continues
across the Midwest, it will push the cold front into the Mid South.
However, as upper flow becomes southwesterly, the front will stall
near or just northwest of the forecast area late this weekend into
early next week. Moisture will surge ahead of the front, increasing
rain chances throughout this time frame. Though rain coverage will
generally be coincident with the increase in daytime instability
each day, forcing associated with the front will keep rain chances
greater than climo during the overnight periods as well. /DL/
