Synopsis
Strong high pressure will build over the area through Saturday,
then shift off the coast. A low pressure system will affect the
area early next week.

Near term through tonight
Rest of today: the center of surface high pressure is expected
to track offshore of the DELMARVA peninsula while a surface
ridge is in place across the foothills and piedmont of the
carolinas. The resulting pressure gradient across our area will
lead to steady northeast winds. Sunny skies and minimal mid-
level height rises should result in high temperatures rising to
near normal. The only areas that could see some clouds and maybe
isolated to scattered showers are the coastal waters beyond 20
nm.

Tonight, near term guidance indicates that a secondary high center
will develop along the east facing slopes of the southern
appalachians. Steady northeast winds and partly cloudy conditions
should allow temperatures to cool into the low 50s inland to the low
60s across the beaches. Llvl winds are forecast to remain nearly
parallel to the coast line, keeping isolated to scattered
showers over the warmer waters. Pops over the land zones will be
held to single digit probabilities.

Short term Thursday through Saturday
A deep layered ridge will maintain dry conditions and gradually
warming temperatures Thursday through Saturday. The only
potential for a few rain showers will be across coastal georgia
where moisture will increase Saturday afternoon as the surface
high to the north shifts to the east. Away from the immediate
coast, highs will climb through the low mid 80s with lows in the
50s.

Long term Saturday night through Wednesday
An upper trough is expected to dig into the central united
states Sunday and Monday, bringing a cold front and potentially
a low pressure system through the area Monday through Tuesday.

Model disagreements are large but confidence is increasing in at
least scattered showers and thunderstorms during the period.

Aviation 16z Wednesday through Sunday
Vfr.

Extended aviation outlook:VFR conditions are expected at both chs
and sav terminals through late week.

Marine
Today and tonight: small craft advisories are in effect
for the coastal waters. Ridging across the western carolinas
will prevail, with a pressure gradient across our coastal
waters. The result will be gusty NE winds through this
afternoon, especially beyond 15 nm out. The highest seas will
generally be beyond 10 nm. This evening and overnight winds are
expected to ease a bit as the pressure gradient lowers.

Likewise, seas will trend downward overnight.

Winds seas will gradually relax on Thursday as the surface high
continues to build east. We expect seas to be below 6 ft across
the nearshore waters by late Thursday afternoon and by late
Friday night across the offshore ga waters. A southerly flow
will develop early next week as a low pressure system approaches
from the southwest.

Tides coastal flooding
Strong persistent northeast winds will maintain a risk for
minor coastal flooding with the high tides through Friday.

Coastal flood advisories will likely be needed.

Chs watches warnings advisories

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
