Synopsis
Strong high pressure will build over the area through next
weekend.

Near term until 6 am Wednesday morning
No meaningful changes were made for the early evening update.

Products will be updated once again once the coastal flood
advisory and high risk for rip currents expire at 8 pm.

Strong high pressure will dominate our weather pattern, with the
center of the high forecasted to become centered in the lee of
the central appalachians. Northeast winds around the high will
persist across our area. Though, they are forecasted to weaken
as the night progresses. Despite clear skies, winds should be
just high enough to prevent ideal radiational cooling. Lows are
expected to range from the mid 40s well inland to the low to
mid 50s along the immediate coast.

Short term 6 am Wednesday morning through Friday
At this sfc, dry high pressure will expand across the southeast
united states with little to no precip chances over a majority of
the area through late week. However, a persistent northeast flow
could allow a few showers to drift onshore across coastal locations
in southeast georgia Wednesday night into Thursday. Otherwise, the
main issue through late week will be a noticeable warming trend as a
mid upper lvl ridge of high pressure expands from the gulf of mexico
to the southeast. In general, temps will peak in the mid 70s on
Wednesday, then upper 70s to lower 80s on Thursday, then lower 80s
over most locations away from the coast on Friday. Overnight lows
will also indicate warming conditions, dipping into the low mid 50s
inland to lower 60s closer to the coast Wednesday night, then
mid upper 50s inland to mid 60s near the coast Thursday night.

Long term Friday night through Tuesday
A deep layered ridge will maintain mostly dry weather and
seasonable temperatures through Saturday. A southern stream
shortwave will bring increasing moisture and a potential gulf
surface low into the area early next week. This would be our
next chance for measurable rainfall, potentially Sunday but more
likely Monday into Tuesday.

Aviation 00z Wednesday through Sunday
Primary concerns:
* none -VFR
extended aviation outlook:VFR conditions are expected at both chs
and sav terminals through late week.

Marine
Tonight: the pressure gradient is expected to decrease this
evening and overnight, allowing winds gusts to gradually trend
downward. Small craft advisories will remain in effect for all
of the coastal waters, excluding the charleston harbor.

Wednesday through Sunday: a fairly tight pressure gradient will
prevail over the coastal waters while high pressure remains
centered just to the north. The pattern will result in persistent
20-25 kt northeast winds over most waters with gusts up to 30 kt
over offshore georgia waters Wednesday. Seas will also peak between
4-6 ft in nearshore waters and 6-9 ft in offshore georgia waters.

Winds seas should then gradually weaken subside into the weekend as
the sfc high becomes centered overhead. Small craft advisory
conditions are expected over the nearshore waters into Thursday
afternoon, mainly due to seas. Offshore georgia waters should
experience small craft advisory level conditions into Saturday and
potentially into Sunday.

Tides coastal flooding
A coastal flood advisory is in effect for the low-lying areas of
southeast sc and southeast ga for this evening's high tide.

Strong persistent northeast winds will push higher water levels
to the coast this week. Minor coastal flooding will be possible
around high tides into Thursday or Friday. Coastal flood advisories
will likely be needed.

Chs watches warnings advisories

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.
