Synopsis
Could possibly tie or break record for coldest high
temperatures today as arctic high pressure builds into the
carolinas. A slight moderation will occur Thursday into Friday
but a coastal trough will bring rain by Thursday night. The
weekend looks unsettled especially along the coast as a series
of fairly strong areas of low pressure form offshore.

Near term through Thursday
Northerly winds behind the recently passing cold front has brought
much cooler temperatures region wide. Temperatures this morning
were in the upper 20s to lower 30s, which was between 20 and 25
degrees colder than 24 hours ago. As cold high pressure settles
into the region, clouds will gradually decrease through the day with
plenty of sunshine but highs in the mid 40s. As high pressure
slides to the east, a front will be pushed inland from the atlantic
that is associated with surface cyclogenesis that will be the next
chances for rainfall Thursday. Afternoon highs Thursday will
increase into the 50s with chances for light rain Thursday afternoon
and evening.

Short term Thursday night through Friday night
Sharp coastal trough will extend up to carolina coast from low
pressure off of the ga coast. Very shallow cold air at the sfc
will be overrun by much warmer and moister air only a few
thousand ft above maintaining clouds and rain in the forecast
through thurs night into fri. As low pressure moves north
through thurs night, isentropic lift will increase as winds
increase enhancing rainfall amounts with embedded areas of
heavier rain, mainly along the coast into fri. The rainfall may
diminish for a little while Fri as low pressure lifts north and
trough aloft shifts eastward decreasing isentropic lift and
advecting drier air in through the mid levels. But, this will be
short lived as cutoff low in the mid levels tracks across the
southeast Fri night, with deepening sfc low off the coast.

Rainfall should increase once again. Overall, expect plenty of
clouds and periods of rain thurs night through Fri night,
especially closer to the coast. Clouds and rain will keep temps
cooler during the day, well below normal and overnight lows
above normal.

Long term Saturday through Tuesday
Deep low will move up through the southeast coastal waters with
increased isentropic lift. Expect periods of rain and cool gusty
northerly winds through Sat before low lifts off to the east
northeast leaving a deep northerly flow of cooler and drier air
as high pressure builds in behind it. Rainfall should diminish
through Sunday, but clouds may hang around as another low may
track up the coast Mon into tues spreading more clouds and rain
across the area. Overall, an unsettled period with afternoon
temps well below normal and it could feel quite raw at times
with gusty northerly winds.

Aviation 06z Wednesday through Sunday
Vfr conditions for area terminals with clearing skies and remnant
post-frontal gusts lasting into this afternoon.

Extended outlook...VFR through early Thu under high pressure. Better
chance for subVFR Thu night and especially Fri Sat as moisture from
the gulf along with potential developing coastal low pressure
impacts area.

Marine
Latest model guidance has winds and waves hanging on longer than
previous forecasts, so the gale warning has been extended for the
offshore waters. The gale for offshore sc waters expires at 11 am
and the nc waters at 3 pm. High pressure will gradually take over
and conditions will improve offshore this afternoon, although small
craft may find seas still a bit rough through this evening. A front
will approach shore as a low pressure system forms and will bring
rain chances, heavy at times, Thursday. Main wave train from the
north at 8 seconds with some diminishing swells from the south at 6
seconds and from the east at 10 seconds.

Coastal trough becomes more defined through thurs night into fri
as low pressure deepens off the ga coast and then tracks north.

This low should deepen off the carolina coast over the weekend
before it tracks off to the NE through Sunday. This should
maintain a stiff northerly flow from Fri through the weekend,
diminishing Sun into early next week as low lifts off to the
north. Seas will build through Fri in increasing northerly
winds. Depending on how this low evolves, should see strong sca
conditions over the weekend with strong northerly winds and seas
up to 7 to 11 ft, especially Fri night through early Sunday. Can
not rule out possible gales on Saturday.

Tides coastal flooding
Large tidal ranges associated with this month's full moon in
combination with stiff north-northeasterly winds this morning
should result in minor coastal flooding at the beaches and
downtown along CAPE fear river.

Ilm watches warnings advisories
Sc... Freeze warning until 9 am est this morning for scz054>056-058.

Nc... Freeze warning until 9 am est this morning for ncz106>110.

Marine... Gale warning until 7 am est this morning for amz250-252-254-

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.
