Area Forecast Discussion
National Weather Service Charleston SC
132 AM EDT Fri May 5 2017

.SYNOPSIS...
A cold front will shift offshore early Friday. High pressure
will build across the region Friday bringing drier and cooler
conditions through early next week. A backdoor cold front could
approach the area next Thursday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
A band of convective rains was moving through se SC with plenty
of deep layered shear remaining but instability was very
limited except right along the central and upper SC coast. Cells
continue to show signs of rotation with 40+ KT of 0-1 KM bulk
shear. There is a non-zero chance of a brief tornado the new few
hours to the east of I-95 in SC with pockets of downpours in
the heavier showers and storms. Until the cold front moves
through late tonight there will still be scattered showers and
t-storms. Noticeably cooler air will arrive behind the front,
with lows 55-60F west of I-95 and lower to middle 60s further
east. Winds will still be gusty with a 30-40 kt low level jet to
pass through, but much less so than earlier.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY/...
An upper trough will remain over the east coast during the short
term. At the surface, low pressure over the OH Valley Friday will
slowly move to the northeast into Saturday, pulling a cold front that
is offshore further to the east. Cooler high pressure will build
into the Southeast behind the front Friday into Saturday. Another
cold front could move through our area from the north on Sunday,
bringing a reinforcing shot of cooler air. No precipitation is
expected with this front. Overall the short term will remain dry,
with the exception of some showers offshore Friday night into
Saturday morning, associated with the cold front moving further
offshore. High temperatures will be a few degrees below normal, with
the coolest day being Friday. Friday night will be the coldest night
in the short term with temperatures falling into the upper 40s far
inland, and the lower 50s at the immediate coast. It will also be
breezy during the daylight hours Friday and to a lesser extent
Saturday due to a strong gradient across the area. A Lake Wind
Advisory may be needed, especially Friday.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Generally cooler than normal and dry conditions to prevail through
about Tuesday as a deep upper trough lingers across the East Coast.
Cannot rule out a few showers Tuesday night through Thursday and
Wednesday as a weak low pressure and cold front approach from the
north. Expect a gradual warming trend through the period with the
coldest temperatures Monday morning in the 40s inland.

&&

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
KCHS: Scattered showers and a few tstms will impact the
terminal prior to daybreak ahead a cold front. MVFR conditions
are expected at times prior to 10Z. VFR and gusty surface winds
will persist through the day but conditions will be VFR after
the front passes later this morning.

KSAV: Conditions have become VFR and while there is a chance for
a brief period of MVFR cigs along and ahead of the cold front,
VFR will prevail the next 24 hours. Gusty southwest winds will
also persist with deeper mixing this afternoon perhaps resulting
in a few gusts near 30 KT at times.

Extended Aviation Outlook: VFR. Breezy/gusty conditions are expected
again Saturday during the daylight hours.

&&

.MARINE...
Overnight: Elevated winds and seas will impact the coastal
waters, including Charleston Harbor, due to a tight cyclonic
gradient around deep low pressure in Kentucky. The gradient is
such that solid SCA's will impact all coastal waters, except for
a Gale Warning across AMZ350 where the best mixing will occur
of a 35-45 kt low level jet. Within a favorable fetch, seas will
reach 5-8 ft, with even some 9 footers across the outer GA
waters.

Friday through Tuesday: Small Craft Advisory conditions expected
through Saturday behind a cold front as deep low pressure remains
across the region. Winds will remain elevated into Sunday before
tapering off as high pressure builds in.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...None.
MARINE...Small Craft Advisory until 10 PM EDT this evening for AMZ330.
     Small Craft Advisory until 6 PM EDT Saturday for AMZ352-374.
     Gale Warning until 6 AM EDT early this morning for AMZ350.
     Small Craft Advisory until 4 PM EDT Saturday for AMZ354.
