.SYNOPSIS...
Surface high pressure will prevail into the weekend.
&&
.NEAR TERM /THROUGH TONIGHT/...
The mid and upper levels will consist of weak troughing through this
afternoon and tonight over the southeastern states. At the surface a
stationary front will remain to the south of the region, with high
pressure centered over New England building in from the north. The
dominating high pressure will yield a dry forecast. Temperatures
this afternoon will peak below normal, generally in the upper 70s to
low 80s. Additionally, dew points across the region are in the mid
50s to low 60s, creating rather fall-like conditions. Gusty NE winds
will persist through this afternoon, around 15 to 20 mph,
diminishing with sunset. Despite some high cloud cover and
slightly elevated winds, temperatures tonight are forecast to
dip into the upper 50s inland with 60s elsewhere.
&&
.SHORT TERM /WEDNESDAY THROUGH FRIDAY/...
Wednesday through Friday: Aloft, troughing will prevail across the
region with the trough amplifying from the Mid Atlantic southward
into Friday. At the surface, high pressure will prevail inland along
the Eastern Seaboard through the end of the week. Model consensus
continues to favor dry conditions across the forecast area with
gradually warming temperatures. For Wednesday we anticipate low to
mid 80s for southeast SC and upper 80s for southeast GA. Then for
Thursday and Friday, mid to upper 80s will be common with a few
spots hitting 90 across interior southeast GA.
&&
.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
Troughing should prevail through the weekend before attempting to
shift offshore early next week as ridging starts to extend in from
the west. Still not much change expected at the surface as high
pressure remains the dominant feature and we remain in a relatively
dry pattern. Overall the forecast is dry with temperatures returning
to the upper 80s and low 90s by late this weekend or early next
week.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Prevailing VFR through the 18Z TAF period at KCHS/KJZI/KSAV. Gusty
NE winds will wane with sunset tonight, with NE winds remaining
slightly elevated overnight around 10 knots.
Extended Aviation Outlook: Mostly VFR though there is a low end
potential for few periods of restricted ceilings due to late
night/early morning stratus.
&&
.MARINE...
Rest of Today and Tonight: A stalled front will be positioned just
south of the local waters through the period while high pressure
build in across the land zones. This will yield a pinched pressure
gradient, resulting in gusty NE winds. Gusts through this afternoon
and into tonight. Seas in the nearshore waters around 5 to 6 ft this
afternoon will diminish to 4 to 5 ft tonight. Seas in the 20 to 60
nm offshore GA waters this afternoon around 6 to 8 ft will diminish
to 5 to 6 ft tonight. Small Craft Advisories are in effect for all
marine zones through this afternoon and into tonight, with the
nearshore waters expiring tonight and the offshore GA waters
extending into Wednesday.
Wednesday through Sunday: Northeast flow is expected to prevail
across the local waters through the weekend. Wind speeds should
diminish beginning Wednesday night, with a another surge expected to
return Friday into the weekend. Another round of advisories could be
needed during the weekend time period due to increased winds and
seas.
Rip Currents: The combination of persistent northeast winds,
astronomical factors, and elevated swell will yield a Moderate Risk
of rip currents at all beaches Wednesday. Another Moderate Risk at
all beaches is likely again on Thursday under similar
conditions.
&&
.TIDES/COASTAL FLOODING...
Astronomical tide levels will remain elevated through the rest of
the week due to the recent full moon and upcoming lunar perigee
(9/10). Total water levels will also be high with the tidal
departure increasing due to the pinched pressure gradient/elevated
northeast winds.
Tidal departures will then start to come down Thursday into Friday
as the pressure gradient beings to relax.
