Synopsis
High pressure will build in from the south though tonight. A
strong cold front will approach the area and push through
tomorrow, bringing colder temperatures Tuesday night and
Wednesday. Another cold front will cross Thursday night.

Near term until 6 am Tuesday morning
As of 3 pm Monday... The latest meso analysis is showing a
shortwave over the upper midwest which will dive down southeast
overnight accompanied with an approaching dry cold front for
the SE region. Winds will be initially be light winds clear
skies leading to strong radiational cooling and rapidly falling
evening temperatures. As the front approaches closer to the
region, pressure gradient will tighten after midnight.

Temperatures will drop quickly thru midnight, then as the wind
increases slightly, temps will become steady. Expect overnight
lows in the mid-30s to low 40s inland and mid-40s to around 50
along the beaches.

Short term 6 am Tuesday morning through 6 pm Tuesday
As of 3 pm Monday... An increase of mid to high clouds ahead of
the approaching cold front. Models have a good agreement with
the front entering into eastern nc around noon and pushing
through late afternoon early evening. There is limited amount of
moisture associated with the frontal passage with the highest
pw 0.50 inches, so not expecting any type of precip. Low level
thicknesses will slightly be higher than Monday and supports
highs in the in the mid upper 50s inland and upper 50s to around
60 degree along the beaches.

Long term Tuesday night through Monday
As of 300 am mon... Another shot of arctic air will surge in tue
night and Wed as upper trof crosses the region. Models are dry
with limited moisture so no precip expected. Very cold Wed with
lows in the mid 20s inland to low 30s coast and highs mainly
upper 30s to lower 40s.

Another front moves through late in the week. Timing of this
feature much in question. HPC surface prog has it passing
through Thursday. However, the latest run of both the GFS and
the ECMWF are much slower with it, bringing it through fri
afternoon. Because of this, I will continue the dry forecast for
late week as moisture still appears limited. The weekend looks
dry with high pressure building into the region from the
southwest.

Highs Thu upper 40s to lower 50s and mostly lower mid 50s fri
and upper 40s to lower 50s sat. Temps moderate a bit Sunday with
highs in the mid upper 50s.

Aviation 21z Monday through Saturday
Short term through Tuesday afternoon ...

as of 1155 am Monday...VFR conditions are expected this
afternoon through Tuesday. A dry cold front will bring a wind
shift Tuesday, butVFR conditions and light winds will
continue.

Long term Tuesday through Friday ...

as of 300 am mon...VFR dry weather expected with partly cloudy to
mostly clear skies.

Marine
Short term through Tuesday night ...

as of 3 pm Monday... The latest buoy obs are showing light and
variable winds across coastal waters and seas 1-3 ft. Winds will
become SW 5-10 knots tonight as high builds into the coastal
waters. Then late tonight, the wind gradient will tighten as a
strong cold front approaches the area and SW winds increase to
15-25 knots. Seas will remain 1-3 ft through this evening and
gradually build overnight. Expect seas to build to 4-7 ft
Tuesday morning and peaking 6-9 ft over the outer central and
southern waters in the afternoon. Therefore, a small craft
advisory have been issued for all of the near shore waters,
sounds and rivers. A few gusts to gale force will be possible
Tuesday as the front pushes through over the coastal waters.

After the frontal passage, NW wind surge 25-30 knots is very
possible and have issued gale watches for all coastal waters and
sounds Tuesday night.

Long term Tuesday through Friday ...

as of 300 am mon... The long term will feature mostly poor
boating conditions for the coastal waters and sounds. Two dry
fronts will pass through the area, one on Tuesday and the other
on Thursday.

The flow will be westerly through the period, with the strongest
winds Tuesday night into Wednesday at 20-30 knots on the
coastal waters and sounds. A gale watches are now in effect for
those zones. A few gusts to gale force will be possible Tuesday
and Tuesday night on the coastal waters.

Winds Thursday and Friday will average 10-20 knots, with 20-25
knots possible from hatteras to ocracoke on Friday.

Seas on the coastal waters will be highest Tuesday and Tuesday
night, averaging 5-9 feet. Seas will remain elevated for the
remainder of the period, with small craft conditions continuing
through the end of the week for most of the coastal waters.

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.
