.PREV DISCUSSION... /issued 1135 PM CDT Thu Jun 22 2017/
DISCUSSION...See updated information for land areas below.
UPDATE...
Late evening surface analysis shows the surface low associated with
Cindy's remains spinning across southern Arkansas between El Dorado
and Little Rock. Water vapor imagery over the past several hours
shows the deep moisture plume associated with the system is
continuing to be pinched off by an upper low retrograding toward the
Yucatan.
Short range ensembles indicate the deepest values of moisture
transport will gradually shift westward into Mississippi through
Friday, as the mid-level portion of the storm heads across the
ArkLaTex. All-in-all, expect convective coverage/rain rates to
decrease slightly over the region heading into Friday. Additional
rainfall amounts up to 3 inches will remain possible overall, with
higher totals possible in the heavier downpours and in places where
the convection trains. Given the high rainfall totals we've seen
since Tuesday, I've made no changes to the Flash Flood Watch.
Inundation along coastal areas will remain a problem heading into
Friday morning. Even though we've recovered a bit from this morning,
long period swells continue and a check of tidal gauges across
the region show water levels remain between 1 and 3 feet above
predicted MLLW levels. I cancelled the Coastal Flood Warning for
Mobile and Baldwin Counties earlier this evening and replaced it
with a Coastal Flood Advisory. Tidal gauges will continue to be
monitored, and it's possible that we may need to reissue the
Coastal Flood Warning prior to sunrise. /Butts/

DISCUSSION...Updated for latest aviation discussion below.
AVIATION...
00Z issuance...Gradually improving conditions are expected over

continue at mostly MVFR levels through Friday. Visibility will be
VFR except lower in and around showers. 05/RR
PREV DISCUSSION... /issued 409 PM CDT Thu Jun 22 2017/
NEAR TERM /Now Through Friday/...For tonight, large cyclonic
gyre associated with the weakening remnants of tropical cyclone
Cindy was centered over the central state borders of TX/LA today.
Well east of Cindy's large scale circulation, a narrow plume of
deep tropical moisture was aligned north to south from the central
Gulf coast to way down across the Gulf of Tehuantepec.
Forecasters have noted that a deep layer ridge positioned over the
southwest Atlantic has been building west, causing the plume to
shrink and will begin to take on a northeast to southwest
orientation from the Tennessee River Valley to off the LA coast
tonight. Considering these trends and some lowering in amount of
deep moisture, have backed off the flash flood threat to limited
east of I-65 while maintaining an elevated threat west of the
interstate. Take note, given antecedent soil moisture to capacity,
any additional heavy rains will easily lead to runoff bring
flooding problems.
The majority of the impacts will continue across the coastal zones
and offshore tonight. Strong south winds maintain high seas, long
period swell results in large breakers, coastal flooding, minor
beach erosion and a risk of dangerous to potentially deadly rip
currents. Also, a few tornadoes remain possible through this
evening.
As the pressure gradient force begins to relax over the
coastal zones tonight, southerly wind speeds are forecast to fall
below wind advisory criteria after 6 PM and an extension is not
expected to be required. As far as coastal flood warnings, an
extension is made to Mobile and Baldwin counties thru 1 AM Friday
followed by an advisory through remainder of the day. East over the
northwest Florida Panhandle, coastal flood advisories remain in
effect thru Friday. No changes made to rip current and high surf
impacts. Please see products issued by the WFO Mobile on site
specific forecasts/impact discussions. /10
For Friday, the remnant low of Cindy is expected to be located
near east central Arkansas Friday morning and moves east-
northeastward to central Tennessee during the day. As this occurs,
a cold front located over the eastern Plains Friday morning moves
to the mid Mississippi river valley Friday afternoon, nearly
merging with Cindy's remnant low in the process. The axis of an
anomalously high moisture plume is expected to have shifted to
near the western periphery of the forecast area Friday morning and
remains generally in this position through the day. Precipitable
water values during the day will range from around 1.5 inches over
the easternmost portion to 2.0-2.25 inches generally along and
west of I-65.
The entire forecast area is essentially water-logged and extremely
vulnerable to additional rainfall which could result in flash
flooding. Very little, if any, precipitable is expected over the
eastern portion of the area on Friday, but additional amounts of 1
to 2 inches can occur over the western portion of the area with
locally higher amounts, mainly over southeast Mississippi and
interior southwest Alabama, which will fall on completely saturated
soils. Considering this, have continued the Flash Flood Watch for
Stone, George, Perry, Greene and Wayne counties in southeast
Mississippi and Washington and Choctaw counties in southwest Alabama
through Friday. Have gone with likely pops in the flash flood watch
area tapering to slight chance pops over part of south central
Alabama and the western Florida panhandle.
Winds will be a bit breezy over the area on Friday, up to 15 to
20 mph, but look to remain below Wind Advisory criteria. With long
period swell continuing to impact the area through Friday, will
continue with a High Risk of Rip Currents and Heavy Surf through
the day on Friday. A Coastal Flood Advisory is also in effect for
beaches through Friday. /29
SHORT TERM /Friday night Through Sunday night/...The cold front
near the mid Mississippi river valley early Friday evening
advances into the Gulf coastal states and eastern states later
Friday night, merging with the remnant low of Cindy over the east
central states in the process. A broad longwave trof over the
central states slowly shifts into the eastern states through
Sunday night, while the cold front continues slowly southward
through the forecast area to near the coast Saturday into Saturday
night where it lingers until moving offshore Sunday night. With
the slow advance of the upper trof, the highest values of deep
layer moisture over the western and central portion of the area
(precipitable water values of 2.0-2.25 inches) shift from mainly
along and west of I-65 to across the entire area. With abundant
deep layer moisture combined with the slow moving frontal boundary
and saturated soil conditions, there is a potential for flash
flooding for much of the area mainly on Saturday into Saturday
night, and possibly continuing into Sunday. Have held off on
extending/expanding the Flash Flood Watch during this period for
now but will need to closely monitor on subsequent shifts. Have
gone with likely pops for most of the area on Saturday then good
chance pops follow for Sunday, tapering to chance or possibly
slight chance Sunday night. /29
LONG TERM /Monday Through Thursday/...The broad longwave trof
over the eastern states weakens and moves off into the western
Atlantic on Wednesday, while the cold front continues further
south into the Gulf. Will have chance pops on Monday, but lower
pops will probably ultimately be needed, depending on how far into
the Gulf the front manages to go. Pops otherwise taper off
through Wednesday to slight chance near the coast and dry further
inland. Chance pops return on Thursday as a return flow sets up
over the area. Highs will be in the lower to mid 80s on Monday
then trend to mid to possibly upper 80s by Thursday. Lows Monday
night and Wednesday night range from the mid 60s inland to the
lower 70s at the coast, except for a bit cooler Tuesday night
with lower 60s inland ranging to near 70 at the coast. /29
MARINE...A Small Craft Advisory remains in effect for the bay
waters until 4 am Friday and until 10 am Friday for the remainder
of the marine area as a strong southerly flow gradually subsides.
A cold front meanwhile approaches from the north and moves through
the marine area Sunday night with a light to moderate
northeasterly flow in the wake of the front. /29

Within this axis, bands of showers and scattered storms look to lift northeast across the local area with the better coverages setting up along and west of Interstate 65. With soil moisture to capacity, any additional heavy rains will likely lead to runoff and additional flooding problems. Dangerous surf conditions will continue, with long period swell and breakers of 5 to 8 feet moving up into the surf zone. A high surf advisory and a high risk of dangerous to potentially deadly rip currents continue. Minor coastal flooding of the typically flood prone coastal roads along Alabama and northwest Florida panhandle beaches is likely to continue.
