Synopsis
A cold front will move off the coast this evening. High pressure
will rebuild over the area for the weekend. Low pressure approaches
from the west Monday, with a trailing cold front crossing the area
Monday night.

Near term until 6 am Saturday morning
As of 315 pm edt Friday...

scattered convection currently across NRN va tracks ese ahead
of the cold front before moving offshore arnd 00z. Will keep chc
pops (low end likely across the ERN shore) in the grids thru 00z,
mainly shwrs but with isltd thunder and psbl small hail graupel
across the ERN shore and zones near the ches bay where the best
instability will be. Temps in the 50s.

Otw, clearing behind the front this evening but remaining breezy
due to the tight pres gradient. Lows in the 30s.

Short term 6 am Saturday morning through Monday night
As of 315 pm edt Friday...

sfc high builds into the ohio valley sat, overhead Sat nite then
pushes off the carolina coast sun. Dry through the period. Highs sat
around 60 west of the bay, holding in the 50s near the water. Lows
sat nite mainly in the 30s, except a few upr 20s in those normally
colder spots. Return flow begins a warmup sun. Highs in the 60s west
of the ches bay, 50s along the coast. Increasing clouds Sun nite
ahead of a leading warm front from the low apprchg from the west. A
shwr psbl across NRN most zones late. Lows in the 40s.

Shwrs overspreads the area west to east Mon as the low pressure
tracks across the area. Highest pops in the afternoon. Mild ahead of
the trailing cold front with highs in the 60s except some 50s at the
beaches. A rather strong trailing cold front pushes across the area
mon night with pcpn ending behind it after midnite. Highest pops in
the evening. Kept it all liquid for now as it seems the pcpn will
end before the cold air filters south. Lows in the 30s north, 40-45
south.

Long term Tuesday through Friday
As of 315 pm edt Friday...

strong cool canadian high pressure is progged (per 22 12z
numerical guidance) to build in from the N Tuesday in the wake
of the departing cold front and area of low pressure. There is
some timing differences amongst the guidance with respect to
moisture, with the GFS faster to bring in drier air, and the
ecmwf cmc slower to clear the moisture. Therefore, a 20-40% pop
has been maintained Tuesday morning, mainly for SRN va NE nc.

Highs Tuesday are forecast to be ~10-15f below seasonal
averages, with highs ranging from the mid 40s along the coast,
to around 50f inland. Lows Tuesday night range from the upper
20s N the the mid 30s se. Cool high pressure remains over the
area Wednesday into Wednesday night with dry and mostly
sunny clear conditions, and high temperatures in the upper 40s
to mid 50s, followed by lows in the low 30s N NW to around 40f
se. High pressure slides offshore Thursday into Friday resulting
in a warming trend (but remaining dry). Forecast highs reach
the mid 50s along the coast to low mid 60s inland Thursday, and
then upper 50s low 60s along the coast to mid upper 60s inland
Friday. Lows Thursday night Friday morning range from the upper
30s to mid 40s, then mid 40s to low 50s Friday night Saturday
morning.

Aviation 01z Saturday through Wednesday
As of 830 pm edt Friday...

a cold front producing a line of rain showers and wind gusts up
to 40 kt have moved through all sites this evening except kecg.

Line is weakening as it moves into nc. Kecg can see a quick
gust up to 35 kt as the line moves through. Winds had decreased
to 10 kt immediately after the passage of the line of showers.

Winds should increase tonight back to 15 kt with gust up to 25
kt before decrease, again, late tonight and into tomorrow
morning. Then once again, winds will be increasing 15-20 kt
with gust up to 25 kt for Saturday. Behind the cold front, skies
have cleared and will remain clear through the rest of the 00z
taf period.

Outlook:
high pressure will continue to build in for the weekend. Low
pressure along with a strong trailing cold front approaches from
the NW Monday, and crosses the area Monday night, with high
pressure building in from the N Tuesday. There is a likelyhood
for degraded flight conditions Monday night into early Tuesday.

Marine
As of 315 pm edt Friday...

gusty winds will continue over the waters the rest of the afternoon,
with no changes to current headlines. A secondary cold front will
pass over the waters this evening with an accompanying area of cold
air spilling into the region. The CAA surge combined with the steep
pressure gradient will result in restrengthening of wnw winds this
evening and overnight, especially across the northern bay and
offshore zones where winds will increase to 25-30 knots with gust 35-
40 knots. Elsewhere, strong SCA conditions and headlines will
continue for the rivers, lower bay, currituck sound and offshore
zones outside of the gale warning area. A brief surge of wind gusts
to 35 kt will accompany the front as it crosses all waters this
evening, but duration won't be long enough to expand current gale
warning. Will issue smws as needed. Waves in the bay tonight will
generally run 3-4 feet with seas offshore 5-7 feet.

Conditions begin to improve by Saturday afternoon with decreasing
winds and waves seas as high pressure builds closer to the area.

Marine conditions will be much improved Sunday with high pressure
overhead. The next system nears the area Monday with modest south
and southwesterly flow preceding it. A strong cold front is forecast
to cross the region Monday night into Tuesday with strong nne winds
in its wake. Scas will be likely, with the possibility of gales for
the southern 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.
