Area Forecast Discussion
National Weather Service Charleston SC
118 AM EST Fri Jan 27 2017

.SYNOPSIS...
Cooler high pressure situated well to the west will steadily build
in through the weekend. Another cold front will pass through late in
the weekend, followed by more high pressure into the middle of next
week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
FYI: The NWS Gateway is experiencing a significant system loss
of data, which appears to be impacting the distribution of
METARS and some 27/00z model data. Support personnel are on
site. Refer to the latest SDM/NWS Administrative Message (AWIPS
ID: ADMNFD, WMO Header: NOUS42 KWNO) for additional status
messages.

A lingering band of thick cirrostratus will linger for a few
more hours until weak shortwave energy currently crossing
Mississippi and Alabama propagates east. Still expect skies to
clear early Friday morning. Clouds will linger the longest near
the Altamaha Sound, so adjusted overnight lows up a degree or
two in the Darien area and the adjoining coastal areas up
through Liberty County to take this into account. Otherwise,
lows form the upper 30s inland to the mid 40s along the beaches
look on track.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY/...
Friday and Friday night: Fast west-southwest flow will prevail aloft
as the area sits south of a approaching trough with a strong
positive tilt. At the surface, a large and strong area of high
pressure situated over the Mountain West will extend eastward toward
the area and help to push cooler air into the forecast area. Overall
this period will be quiet with no chance for rain and just cool
temperatures. Skies for most of the day should be clear, before high
clouds begin to increase in coverage thanks to a 175 knot upper jet
that sinks southward across the area Friday night. Friday afternoon
will be breezy with frequent gusts into the 25 mph range, which will
make it feel cooler than the forecast highs in the mid to upper 50s.
Overnight lows are expected to fall to around freezing inland, to
the mid/upper 30s closer to the coast.

Saturday through Sunday: The fast west-southwest flow aloft will
continue through the aforementioned mid/upper level trough will be
positioned closer to the area. The trough will eventually amplify
and become less stretched out, swinging more concentric vorticity
maxima through the area. At the surface, the area will be within a
broadly cyclonic flow regime and a weak surface wave is progged to
pass well to the south across the Florida Peninsula. Dry air will
keep the forecast dry through the weekend, with the only expected
precipitation to occur in Florida with the surface wave. High clouds
will continue to prevent clear skies from happening through the
weekend. Temperatures will remain on the cool side, with highs in
the mid/upper 50s. Similarly, each afternoon will be breezy with
frequent gusts into the 25 mph range.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
A potent vort lobe rounding the base of an upper trough will send a
cold front quickly through the area Sunday night/early Monday.
Moisture is really lacking, so no precipitation chances are in the
forecast. Surface high pressure will then return in its wake and
persist through mid week before another cold front crosses Wednesday
night. Lack of deep moisture will preclude any rain chances.
Temperatures will mainly be near or below normal through the period.

&&

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
VFR. Gusty west surface winds are likely again Friday afternoon
as the mixed layer deepens.

Extended Aviation Outlook: Gusty west winds possible in the
afternoons through the weekend.

&&

.MARINE...
Overnight: Modest offshore flow will be strongest beyond 20 NM
off the coast, remaining below advisory levels.

Friday through Tuesday: Winds will temporarily back down from Small
Craft Advisory levels on Friday as the pressure gradient weakens a
bit. Then winds and seas will increase for most of the weekend
thanks to a improving gradient and persistent westerly flow.
Additional Small Craft Advisories will likely be needed at some
point this weekend, perhaps most likely on Sunday. The elevated
conditions will continue through Monday before high pressure returns
Monday night into Tuesday.
