Synopsis
The high will weaken early next week with a weak cold front
stalling over the area mid week, then likely shifting back
northward as a warm front late in the week.

Near term /through tonight/
Today into tonight, the forecast area will remain under the axis of
a mid level ridge as a strong low pressure system tracks east across
the southern great plains. At the sfc, the center of high pressure
is forecast to slide over bermuda. Sfc winds should remain from the
ne through the early daylight hours, then veer from the SE by mid
afternoon. Afternoon high temperatures will likely range from the
mid to upper 70s as temps over the waters favor the low to mid 60s.

Given the forecast wind shift and decent land/water temperature
difference, it appears very favorable from a sea breeze to develop
during the early afternoon and drive west. Accounting for the sea
breeze, I will populate the high temps with bias corrected
temperature guidance, indicating a tight temperature gradient along
the coast. Hourly temperatures will feature cooling mid to late
afternoon temps in the wake of the sea breeze. A few fair weather cu
may develop along and ahead of the boundary, but capped by a
significant inversion around h8. High clouds well ahead of a cold
front will increase across eastern ga and sc tonight. SE winds
should weaken to 5 kts by the late night hours. Min temps should
favor the low 50s inland to the upper 50s near the beaches.

Short term /Saturday through Monday/
Atlantic high pressure will persist through the period, although
will generally weaken with time over the local area. Some shortwave
energy will shift through on Sunday on the southeast periphery of
deep low pressure over the midwest with additional energy
approaching Monday ahead of a secondary upper trough. This pattern
will lead to warmer than normal temperatures, likely hitting the
lower 80s inland Sunday/Monday. Some showers and thunderstorms are
expected, mainly Sunday/Monday when instability will be a bit
greater. No significant rainfall and/or severe weather anticipated
at this time however.

Long term /Monday night through Thursday/
A weakening cold front looks to approach the area mid week before
stalling and eventually shifting back northward as a warm front late
in the period. Some showers and thunderstorms are expected, mainly
mon night into Tuesday and again Friday as a shortwave energy moves
through the area. No significant rainfall and/or severe weather
anticipated at this time however.

Aviation /08z Friday through Tuesday/
Vfr. The center of a 1035+mb sfc high will remain off the
delmarva coast, ridging sough across the carolinas and georgia
this morning. By early to mid afternoon, the center of the high
will shift off the carolina coast. Winds will remain steady from
the NE through early this morning, veering from the SE by late
morning. High temperatures over land in the low to mid 70s and
se flow around 10 kts should bring a sea breeze inland by mid
afternoon. I will indicate sct040 along and ahead of the sea
breeze this afternoon. Winds should settle to around 5 kts this
evening.

Extended aviation outlook: low risk of restrictions, mainly
early next week due to mainly early morning low clouds/fog and
afternoon showers/tstms.

Marine
At the sfc, the center of high pressure is forecast to slide over
bermuda. Sfc winds should remain from the NE through the early
daylight hours, then veer from the SE by mid afternoon. Near shore
zones will see decreasing wave heights through today, with 2-3 feet
common late this afternoon. Seas across amz374 will begin the day
between 5 to 7 feet, decreasing to around 5 feet this afternoon. Sca
will remain for amz374 through 6 pm today.

Saturday through Wednesday: no significant concerns with atlantic
high pressure generally in control until a weakening cold front
moves into the area Wednesday. Seas look to be near 6 feet near the
gulf stream through Tuesday which could necessitate an advisory
there. Otherwise winds should mainly be 20 knots or less.

Chs watches/warnings/advisories
Ga... None.

Sc... None.

Marine... Small craft advisory until 6 pm edt this evening for
amz374.

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.
