.SYNOPSIS...
Surface high pressure will prevail through the end of the week.
&&
.NEAR TERM /THROUGH TONIGHT/...
The mid-levels will consist of weak troughing over the
Southeast U.S. this morning. It`ll strengthen this afternoon
through the overnight in response to ridging building over the
Central Plains. At the surface, a stationary front will remain
south and southeast of our area, while High pressure is located
over New England. The periphery of the High will stretch well to
the south and across our area, being the dominant factor in our
forecast. A majority of our area is expected to remain dry.
Though, the NBM keeps a sliver of slight chance to chance POPs
along our GA coast. Expect somewhat breezy NE winds, especially
near the coast during the day, easing into the evening. Some
clouds combined with these winds will keep high temperatures
below normal. Highs should range from the upper 70s to near 80
degrees across our SC counties, to the low/mid 80s across our GA
counties. Lows will range from the lower 60s far inland to near
70 degrees near the beaches.
&&
.SHORT TERM /WEDNESDAY THROUGH FRIDAY/...
Quiet conditions are expected to prevail for the remainder of
the week, as broad troughing aloft and sfc high pressure hold
tight across the region. In terms of PoPs, only have a slight
chance (15- 20%) across southeastern Georgia Wednesday morning -
with the rest of our forecast area remaining dry throughout the
period. Winds during this time, though notably lighter than
Tuesday, will also continue to rise into the teens to lower 20s
along the afternoon seabreeze. Highs in the 80s will be common,
with perhaps a few locations taking a shot at 90 degrees by
Friday. Otherwise, look for lows to remain in the 60s.
&&
.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
Upper level troughing remains the dominant feature aloft in the
long term, though some weak ridging may start to develop Sunday
into Monday. Thus, expect dry conditions and near to slightly
below normal temperatures to continue for the remainder of the
extended period.
&&
.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
06Z TAFs: VFR. Expect gusty NE winds during the daylight hours.
Extended Aviation Outlook: Mostly VFR though there could be a few
periods of restricted ceilings due to late night/early morning
stratus.
&&
.MARINE...
Today and Tonight: A stationary front will remain south and
southeast of the coastal waters, while High pressure is located
near New England. This synoptic pattern is creating an elevated
surface pressure gradient, yielding strong and gusty NE winds.
The gradient and associated winds and seas should start to
trend lower this afternoon, with the trend continuing into the
evening and overnight. Small Craft Advisories are in effect for
all of the ocean zones due to winds and seas. For the
Charleston Harbor the Small Craft Advisory should expire this
afternoon, but it may need to be dropped sooner if winds are not
as gusty as forecasted.
Wednesday through Sunday: Northeasterly flow will persist across our
area heading into the weekend. Should see winds continue to lessen
Wednesday as Thursday, with a secondary surge in gusts possible by
Friday as the pressure gradient tightens. In terms of headlines,
should see most of our SCA drop by daybreak Wednesday, with the
exception of the outer Georgia waters which is scheduled to end by 8
PM. Additional headlines may be needed over the weekend as wave
heights once again rise, but, for now, will continue to monitor
trends in the coming forecast cycles.
Rip Currents: The combination of persistent, gusty northeast
winds, astronomical factors, and elevated swell will yield a
High Risk of rip currents at all of our beaches today and a
Moderate Risk on Wednesday.
&&
.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.
