Area Forecast Discussion
National Weather Service Charleston SC
730 PM EDT Wed Jul 19 2017

.SYNOPSIS...
An upper low will drift south into early this weekend while a
weak surface pressure pattern resides across the region.
Atlantic high pressure will remain the dominant weather feature
into early next week.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
A well-defined outflow boundary generated by convection over the
South Carolina Midlands earlier this afternoon will continue to
march south into Southeast Georgia this evening. The airmass
ahead of the boundary remains quite unstable with SBCAPE in
excess of 3000 J/kg with DCAPE 1000-1300 J/kg. Updated pops to
40-60% for the next several hours across much of Southeast
Georgia as high resolution guidance shows convection potentially
concentrating in the area south of I-16 and west of I-95 through
mid-evening. An isolated severe tstm can not be ruled out in
this area given the level of instability, but 0-6km bulk shear
remains weak. This suggests the risk for severe tstms will be
generally confined to mesoscale boundary interactions. Farther
north across Southeast South Carolina, much more stable
conditions will be found, but it will take a few more hours for
convection to completely wind down. The updated pop forecast
reflects this. The 20/00-13z low temperature forecast has been
updated to reflect the rain-cooled airmass that has settled in
across much of Southeast South Carolina in the wake of earlier
convection.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
A weak upper low will saunter south from near the Carolina coast
towards northern Florida as surface lee troughing becomes
established inland. Being situated between this inland trough and
the Bermuda High offshore will result in persistent south to
southwest surface flow, keeping sufficient low-level moisture
over the area. Mainly isolated coverage of showers and
thunderstorms is anticipated, primarily each afternoon along the
seabreeze, barring any mesoscale influences. Slightly above
normal temperatures are expected.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Large-scale ridging will be overhead for the first part of the week
before modest height falls occur mid week in response to a trough
passing north of the area. Atlantic high pressure will remain in
control at the surface, with strengthening inland troughing
promoting stronger moisture advection. POPs will trend from below
climo Sunday toward more normal values by middle of next week as the
deep layer ridging weakens. Temps will likewise trend toward normal
through the period.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
Mainly VFR. Tstms will be in the KSAV terminal 00-01z with
localized IFR to MVFR conditions possible.

Extended Aviation Outlook: VFR conditions will prevail.

&&

.MARINE...
Tonight: A weak low-level pressure pattern expected over the
waters through tonight as an upper low pressure system moves
south over the coastal waters. No significant winds/seas are
anticipated across the local waters outside thunderstorms which
are more likely near the SC coast through this evening and again
late tonight.

Wednesday through Sunday: Coastal waters will remain on the western
periphery of the Bermuda High through the period. Primarily S to SW
winds between 5 and 10 knots are expected, with seas ranging 2 to 4
feet, with some gustiness possible each afternoon due to the
seabreeze. A strengthening inland trough may result in sufficient
tightening of the pressure gradient to raise winds to 15 to 20 knots
this weekend into early next week, but at this time conditions
appear to remain below Small Craft Advisory criteria.

&&

.TIDES/COASTAL FLOODING...
Elevated tide levels late this week into early next week due to the
lunar perigee and new moon will result in the possibility for minor
coastal flooding during the evening high tides, especially along the
SC coast.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...None.
MARINE...None.
