Synopsis
A cold front will linger just offshore through Tuesday. High
pressure is forecasted to pass to our north Wednesday, then move
into the atlantic during the second half of the week.

Near term through today
Through sunrise: isolated to scattered showers will continue to
develop roughly along east of a hilton head-north charleston-
jamestown line through daybreak as weak low pressure develops
off the charleston county coast. Will hang on to 20-40% pops in
this area to account for this activity.

Today: 26 07z surface observations and various rap mass fields
suggest the cold front is bisecting southeast south carolina and
southeast georgia from southwest-northeast. The boundary will
ooze ever so slowly to the south today, reaching a position
roughly along a reidsville-savannah-buoy 41033-buoy c line this
afternoon as surface high pressure tries to nudge in from the
northwest. Although low-level winds will shift to the north and
northeast ahead of the front in response to weak cyclogenesis
taking place off the charleston county coast, model mass fields
clearly slow definitive moisture and surface-based instability
gradient in the aforementioned corridor across the leading edge
of the cold front.

Expect scattered to numerous showers tstms to develop south of
the front as early as late morning and persist in the savannah-
darien-ludowici corridor through late afternoon as a weak 700
hpa shortwave ripples across southeast georgia and interacts
with moderately unstable warm sector. Convection will steadily
decrease by late afternoon as the pre-frontal airmass becomes
increasingly overturned. Pops will range from 50-70% south of a
glennville-savannah line, to 20-30% along a reidsville-beaufort-
kiawah island line, with 0% pops for the counties bordering the
csra and the southern south carolina midlands. Similar to Sunday,
pwats in excess of 2 inches and the potential for convective
training could yield pockets of flooding, mainly in urban and
low-lying poor drainage areas. An isolated severe TSTM could
also occur with modified rap soundings at darien, hinesville and
jesup showing SBCAPE 2600-3000 j kg with li's as low as -8c
embedded within a belt of 0-6km bulk shear near 30 kt. Highs
will warm into the mid 80s for most locations while a few upper
80s could occur well inland where some decent breaks in the
cloud canopy are possible.

Short term tonight through Thursday
Tonight: convection across the far south will quickly wind down
during the early evening hours. Another weak area of low
pressure is expected to develop along the cold front overnight,
which could push isolated shower activity back onshore along
the beaches early Tuesday. Will show slight chance pops across
the various beach communities to account for this. Lows will
range from the mid-upper 60s inland to the upper 70s along the
georgia coast.

Tuesday through Thursday: a cold front will linger just
offshore Tuesday. At the coast: chance pops remain in place for
our coastal counties due to their proximity near the
moisture lift associated with the front. The highest instability
is far offshore, so we're not expecting any significant storms
across the area. Inland: pops are slight chance as drier air
from a surface high to our northwest builds into the area. The
front will be pushed away from our area Tuesday night as the
high moves closer. The center of the high is forecasted to pass
to our north Wednesday. Most of the area should be dry at that
time, but models hint at some moisture instability across our
southernmost counties in the afternoon evening hours as some
convergence takes place along the sea breeze. We have slight
chance pops to account for this. The high shifts offshore
Thursday, allowing S to SE flow to develop late. This will bring
more moisture into our southern counties and further increase
the threat of showers thunderstorms. High temperatures will be
within a few degrees of normal each day.

Long term Thursday night through Sunday
Nearly zonal flow will persist aloft with surface high pressure in
the atlantic. Southerly flow around the high will advect moisture
into the southeast as an inland trough develops into the weekend.

The result will be the typical summertime shower thunderstorm
pattern with the coverage and intensity appearing to increase each
day into the weekend.

Aviation 06z Monday through Friday
Isolated to scattered showers will remain just east of the kchs
terminal for the next few hours as weak low pressure develops
offshore. Low clouds have filled in at ksav and this should
linger through about 09z before lifting a bit to low-end MVFR.

Until then, ifr CIGS right at alternate minimums will persist.

Vfr should return to both terminals after sunrise. Risk for
showers and tstms will be greatest south of the ksav terminal
this afternoon along a weak cold front. Probabilities for
impacts are too low justify a mention of vcts or tsra at this
juncture. Will reevaluate for the 12z TAF package after
additional high resolution data are reviewed.

Extended aviation outlook: brief flight restrictions are possible
due to showers thunderstorms Tuesday afternoon evening and then
again on Friday.

Marine
Today: north to northeast winds will prevail today as weak low
pressure exits the local marine area. Winds will remain 10 kt or
less with seas 2-3 ft.

Tonight: a light northeast flow regime will hold in place with
speeds around 5 kt. Seas 2-3 ft during the evening hours will
subside to 1-2 ft after midnight.

Tuesday through Friday: a cold front will linger just offshore
Tuesday, bringing changing wind directions. High pressure is
forecasted to pass to our north Wednesday, causing an increase in
the pressure gradient, which will lead to slightly higher winds and
seas Wednesday and Thursday. Conditions will improve as the high
moves into atlantic during the second half of the week, allowing the
gradient to decrease.

Tides coastal flooding
Tides could once again approach shallow coastal flooding
thresholds in the charleston harbor with the late evening high
tide cycle. Tide levels at fort pulaski look to peak just shy of
shallow coastal flooding levels. A coastal flood advisory may be
needed for parts of the lower south carolina coast, especially
for charleston county.

Chs watches warnings advisories
Ga... None.

Sc... None.

Marine... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
