Synopsis
A trough of low pressure will dissipate over the area today.

High pressure will then prevail through late week, followed by
a cold front during the weekend.

Near term until 6 pm this evening
A potent mid level shortwave will swing through the area today.

At the surface, weak troughing will linger over the mid-atlantic
before getting shunted to the north. Cloud cover and lingering
sprinkles will continue to quickly dissipate over the next couple
of hours. Otherwise, highs will peak in the low to mid 60s,
highest across the southeast georgia.

Short term 6 pm this evening through Friday
Tonight: broad high pressure will extend east into the region
tonight as high pressure over the gulf of mexico merges with a
secondary high building southeast out of the northern
mississippi valley. The boundary layer is expected to decouple
this evening resulting in a calm light wind field. These
conditions combined with low dewpoints and clear skies will
support modest radiational cooling. Lows will range from the
upper 30s across interior southeast south carolina to the lower
50s at the beaches. Another round of fog and possible stratus is
expected to develop over the pee dee late tonight some of which
could briefly reach the northern parts of berkeley and upper
charleston counties right around daybreak Wednesday. No
meaningful impacts are anticipated.

Wednesday through Friday: a mid-level trough just off the east
coast Wednesday morning will move away as a ridge approaches
from the west. The ridge is expected to move over the east coast
Wednesday night into Thursday, then offshore Thursday night
into Friday as a trough passes to the distant north. This will
lead to semi-zonal flow across the southeast. At the surface,
high pressure centered over the tn valley Wednesday morning will
shift eastward, becoming located over the southeast Thursday.

The high is forecasted to slowly move offshore on Friday while a
cold front approaches from the distant west. Models are in
great agreement, showing strong subsidence and plenty of dry air
across the region during this time period, so a dry forecast is
on tap. Clouds should increase Friday ahead of the front. The
warming trend continues due to the rising heights, low- level
thickness values, and 850 mb temperatures. High temperatures are
actually forecasted to be above normal for a change on Friday
as southwest surface winds develop.

Long term Friday night through Tuesday
High pressure will be off the southeast coast Friday night, with a
cold front approaching from the west. The 00z models have come into
relatively good agreement, showing the front bringing showers to our
area as it moves through Saturday night. Following the front, high
pressure will build back into the region with drier conditions and
cooler temperatures.

Aviation 17z Tuesday through Saturday
Vfr is expected to prevail through 18z Wednesday.

Extended aviation outlook:VFR through Friday. A cold front could
bring flight restrictions on Saturday.

Marine
Through tonight: west winds will prevail this afternoon with
speeds 10-15 kt across nearshore waters (possibly closer to a
solid 15 over the georgia nearshore waters) with 15-20 kt over
the georgia offshore waters. These winds will persist into the
overnight hours. Seas will average 1-3 ft nearshore legs with
3-5 ft over the georgia offshore leg.

Tuesday through Saturday: high pressure will prevail across the
southeast for most of the extended time period, then move
offshore late in the week. A weak pressure gradient during this
time period should lead to tranquil marine conditions. A cold
front is forecasted to approach from the west late Friday, then
move through the waters on Saturday. Small craft advisories will
probably be needed for most of the waters on Saturday due to
winds, and maybe seas.

Tides coastal flooding
Based on latest observations, we have issued a coastal flood
advisory for the sc coast for 11 am to 2 pm. While tidal
departures should come down a bit as we approach high tide,
levels will likely stay high enough to produce minor coastal
flooding.

Chs watches warnings advisories
Ga... None.

Sc... Coastal flood advisory until 2 pm est this afternoon for
scz048>050.

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.
