Synopsis
High pressure will migrate across the southeast through the
weekend shifting off the coast by early next week, bringing a
warming trend and maintaining dry weather. A cold front will
bring increasing rain chances late Monday into Tuesday. Slightly
cooler temperatures will follow this front, but are expected to
remain at or above seasonable levels.

Near term through tonight
As of 300 am Friday... High pressure will migrate slowly across
the southeast through tonight. The center will remain south,
maintaining a light w-sw flow. The flow aloft will remain fairly
zonal, although a shortwave will begin to move east from the
western gulf coast by early sat. This may throw a few clouds our
way by the end of this period, but overall expect mainly clear
skies. The 850 temps will be on an upward trend in WAA reaching
about 5 to 7c this afternoon with a westerly downslope flow.

Overall, plenty of sunshine today will help temps rebound
nicely, bringing them back up toward normal, reaching mid 50s
most places.

Dewpoint temps will climb a good 5 degrees by tonight, leaving
mid 20s most places. With clear skies and very light winds
tonight, expect temps to drop down between 25 and 30 most
places.

Short term Saturday through Sunday night
As of 300 am Friday... This weekend is going to feel amazing coming
after january temperatures that have so far averaged 7 to 8 degrees
below normal. Surface high pressure moving across georgia on
Saturday will relocate a few hundred miles east of CAPE fear by late
Sunday. Light winds and gradual warm advection should allow temps to
rise into the 60s both days away from the beaches. The land-to-
marine temperature differences should become large enough to
generate a seabreeze both days. For those hoping to enjoy a warm day
on the beach, a january seabreeze is going to spoil your plans as
high temperatures on the sand could have trouble getting out of the
lower to middle 50s with all that cold water nearby.

An upper level low across south texas will move eastward within the
southern branch of the jet and will pass just to our south on
Sunday. Some cirrus clouds could move across the area Saturday
afternoon and Saturday night ahead of this feature. Unusually weak
low-level baroclinicity plus ridging to the north of the upper low
should prevent any surface reflection from developing as the upper
system moves off the ga fl coast Sunday afternoon evening.

Long term Monday through Thursday
As of 300 pm Thursday... Mid upper level trough axis will shift off
the SE CONUS Sunday, along with associated mid-level cloudiness.

This will set the stage for a period of above normal temps to
continue through Wednesday ahead of a cold front. Moisture will
begin to return in low-level southerly flow Monday, with the
possibility of some showers advecting in off the ocean during the
day. Consensus on timing of the frontal passage appears to be
Tuesday morning, and that will coincide with the highest pops during
the period. Models suggest there will be little cold air arriving
immediately behind the front, with temperatures on Tuesday still
rising to around 60. They will, however, drop back into the 50s for
Thursday due to height falls and surface winds becoming more
northerly.

Aviation 12z Friday through Tuesday
As of 12z...VFR conditions through the forecast period. Winds will
continue from the west southwest. Little to no clouds expected.

Tonight, no fog expected. Winds at the boundary layer around 18 kts,
with an unfavorable moisture profile for even ground fog.

Extended outlook...VFR except for possible MVFR in scattered showers
Monday into early Tuesday.

Marine
Near term through tonight ...

as of 300 am Friday... High pressure will migrate slowly across
the southeast with the center to the southwest of the waters
leaving a general w-sw flow across the waters. Winds will remain 10
to 15 kts through the period with seas 2 to 3 ft. SW swells up to 10
sec will dampen out through tonight as shorter period SW wind wave
becomes dominant.

Short term Saturday through Sunday night ...

as of 300 am Friday... High pressure centered over georgia Saturday
morning will slide east and out into the atlantic during the
afternoon hours. This should maintain a westerly wind across the
carolina coastal waters during the morning, but as inland
temperatures exceed 60 degrees during the day a seabreeze should
develop with nearshore wind directions becoming more southerly. A
similar pattern is expected on Sunday, but with the high building
northward closer to the carolinas our overall wind speeds should be
less.

Seas on Saturday will be a combination of 10 second southeast swell
with short period wind waves. By Sunday the wind waves should
disappear leaving only the southeast swell.

Long term Monday through Tuesday ...

as of 300 pm Thursday... Weak southeasterly flow on Monday will
increase to 15-20 knots by Tuesday night ahead of a cold front.

Scattered showers will be possible Monday moving south to north,
with increasing coverage along the cold front, which is
expected to move off the coast Tuesday morning. An offshore wind
after FROPA on Tuesday looks to be relatively weak, generally
10 knots or less, in a relaxed gradient.

Nc... None.

Marine... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
