Area Forecast Discussion
National Weather Service Newport/Morehead City NC
310 PM EDT Wed Aug 23 2017

.SYNOPSIS...
A cold front will cross the area tonight and Thursday. Strong high
pressure will build in from the north Friday through Sunday, while
an area of low pressure develops along the stalled frontal boundary
off the Southeast coast.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
As of 3 PM Wednesday...Widely scattered showers and
thunderstorms have developed in very unstable airmass ahead of
cold front at mid-afternoon with impressive CAPE values over
4000 J/kg. The most persistent activity is over the northern
Outer Banks, while the other storms have not really been able to
get going as of yet. Still anticipate the activity closer to
the front, to the west of Raleigh, to be the more significant
activity as it approaches during the early evening. PoPs are in
the likely category inland this evening, transitioning to the
coast in the overnight hours as the cold front is slated to be
offshore between 09z and 12z Thursday morning. With precipitable
water values at or above 2 inches, some locally heavy downpours
will be possible this evening along with a few strong wind
gusts in stronger to perhaps marginally severe storms. A little
cooler tonight behind the front with lows in the lower 70s
inland to mid 70s coast.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
As of 305 PM Wednesday...With the cold front lingering over the
far southern portion of the CWA or just south, a more stable
airmass with slightly cooler temperatures and slightly lower
dewpoints can be expected for Thursday. Still tricky as to how
far south the front actually gets, and will keep fairly high
PoPs through midday Thursday and will maintain slight chance of
thunder over the far southern zones, while the northern portion
remains more showery in a more stable airmass. High temperatures
will be a few degrees cooler with low/mid 80s for most of the
CWA Thursday.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
As of 3 pm Wed...Below normal temps expected through the
period. Unsettled wx expected late weekend into next week with
the potential for tropical low development along the SE coast,
though much uncertainty remains regarding this system.

Thursday through Friday night...The slow moving front will
continue to push off the south coast Thursday night. Scattered
showers and isolated storms will continue, tapering off from NW
to SE. Strong high pressure will build in from the north
beginning Friday, with broad upper troughing across the area,
while stalled frontal boundary lingers off the SE coast.
Isolated showers Fri and Fri night forecast to remain over the
southern coastal waters. Depending on the track and strength of
the developing low off FL this weekend.

Saturday through Wednesday...Models continue to show possible
tropical low development along the stalled frontal boundary off
the SE coast this weekend into the middle of next week...though
much uncertainty remains on how this system will evolve, given
how far out in time and varying model solutions/lack of run to
run consistency. Low is forecast to strengthen off the FL coast
Sat night and Sun, slowly lifting NE Mon through Wed. Precip
chances increase Sun through Tue as low lifts northeastward.
Models also continue to show the remnants of Harvey interacting
with a frontal boundary over the Gulf Coast region, and pushing
northeast. A lot of uncertainty with how this system will
evolve as well.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
Short Term /through 18Z Thu/
As of 1225 PM Wednesday...Generally VFR for the rest of the
afternoon as scattered cumulus is forming quickly over inland
areas. May see some brief sub-VFR conditions in scattered sea
breeze variety thunderstorms this afternoon, but the main action
will come ahead of the cold front later this evening where some
locally strong storms may occur. Most of the numerical guidance
indicates a brief period of MVFR fog and perhaps stratus in the
wake of the cold front early Thursday morning.

Long Term /Thursday Night through Monday/...
As of 3 pm Wed...Scattered convection will end from northwest to
southeast Thursday evening. VFR/Dry conditions forecast through
the rest of the period for ISO and PGV. Isolated showers could
return for EWN and OAJ Sunday into Monday. Surface winds NE
around 10 kt Friday, NE 10-15 kt Saturday, NE 15-20 kt Sunday
and Monday.

&&

.MARINE...
Short Term /Tonight and Thursday/...
As of 310 PM Wednesday...Southwest winds persist on all coastal
waters and Sounds at 10-15 knots with a few higher gusts at
times. Seas are in the 2-4 foot range with an occasional
5-footer over the central waters. A cold front should gradually
move across the CWA and offshore between 09z and 12z with winds
become W/NW. Gradient becomes weaker behind the front with winds
generally right around 10 knots with gusts to 15 knots and seas
subsiding to 2-4 feet.

Long Term /Thursday through Sunday/...
As of 3 pm Wed...A prolonged period of NE winds 10-20 kt
expected behind the front Thursday night into Friday, strong
winds and rough seas developing this weekend and continuing into
next week. SCA conditions likely to develop this weekend and
continue into next week.

A slow moving front will continue to push off the south coast
Thursday night, with winds gradually becoming northeast. Strong
high pressure will build in from the north Thu night through
Saturday. NNE winds 10-20 kt with seas 2-4 ft through Fri.

Models are still showing the potential for tropical low
development along the stalled frontal boundary off the SE coast
this weekend into early next week. There is still quite a bit of
uncertainty given how far out in time and the varying model
solutions. Strong E/NE winds and rough seas are expected late
weekend into next week. Though given the uncertainty in how this
system will evolve, mariners should continue to monitor this
situation over the next several days.
