Synopsis
A frontal boundary with weak waves of low pressure moving along
it, will push farther southeast of the area today into Friday.

Meanwhile, strong high pressure will gradually build in from the
northwest, then builds eastward across the great lakes and new
england Friday afternoon through Sunday. Low pressure lifts
offshore Monday through Tuesday.

Near term until 6 pm this evening
Early this morning, a frontal boundary was just south of the
region, extending fm well off the va coast SW along the outer
banks of nc and down into ERN sc. Latest radar showed just
isolated showers over NE nc and the south central va piedmont.

Potent shortwave digs over the lower great lakes into the ohio
valley during today, as the frontal boundary pushes farther se
of the region. A few weak waves of low pressure moving along the
boundary, still could trigger isolated to sctd showers over
extrm SE va, but esply NE nc today into this evening. North to
northeast flow will keep sky conditions partly sunny to mostly
cloudy acrs the area. Cooler and less humid, with highs in the
lower to mid 80s.

Short term 6 pm this evening through Friday night
Trough axis slides north of the region tonight into Fri morning,
along with the deepest moisture and best chances for measurable
pcpn. Generally partly cloudy tonight with lows in the lower to
mid 60s most places, except upper 60s near the coast of SE va
and NE nc.

Onshore flow persists fri, as model soundings indicate lingering
low level moisture. Perturbations in the fast west to northwest
flow along with convergence near the coast will result in a
slight chance pop Fri aftn. Some modest instability is indicated,
but will keep only shower wording due to stable onshore flow.

Sky will average partly cloudy with highs in the lower 80s.

Partly to mostly cloudy Fri night, as high pressure builds
north of the region. Lows generally in the lower to mid 60s.

Some locales in the piedmont forecast to drop into the upper
50s.

Long term Saturday through Wednesday
High pressure builds from the great lakes across the saint
lawrence valley and into new england Fri night through Sunday
bringing mild and mainly dry conditions. Highs Sat through
sun will generally be in the upper 70s to low 80s with lows in
the upper 50s to low 60s, and mid upper 60s at the coast. Low
pressure (potentially tropical) eventually develops along a
stalled frontal boundary off the carolina coast early next week.

This could potentially bring some moisture into the region in
the Monday- Wednesday timeframe, but pops are only 20-30% at
this time. Expect a modestly strong ene wind along the coast
with strong high pressure N of the region and developing low
pressure off the carolina coast. High temperatures Monday
through Wednesday remain in the upper 70s to low 80s, with lows
ranging through the 60s.

Aviation 12z Thursday through Monday
Early this morning, a frontal boundary was just south of the
region, extending fm well off the va coast SW along the outer
banks of nc and down into ERN sc. Sfc winds were nw-ne 3-10 kt
at the TAF sites. MainlyVFR CIGS at the TAF sites, except
ifr MVFR CIGS at ecg.

High pressure will gradually build in from the northwest today
into Fri morning, pushing the frontal boundary well SE of the
area. An uptick in nne winds will occur during today, due to a
surge of cool advection. Except for MVFR CIGS at ecg early this
morning, and maybe a few showers there during the day, expect
mainlyVFR conditions at the TAF sites today into Fri morning.

High pressure slowly builds north of the region Fri into sun,
with periods of clouds due to onshore flow. Winds remain north
or northeast.

Marine
Went ahead and cancelled the SCA for the middle of the bay and
lower james river as the winds are not much more than 15 kts.

Kept sca's up another few hours for the southern bay due to a
few gusts around 20 kts. Winds continue to diminish through the
afternoon.

Flow remains ene through the weekend as strong high pressure builds
n of the region across new england. Winds should remain below sca
levels sat, 10-15kt 15-20kt ocean, then increase more significantly
early next week as low pressure (potentially tropical) develops
along a stalled frontal boundary to our south then gradually lifts
nne through the mid week period. A prolong period of onshore winds
increases to 15-20kt 20-25kt ocean (potentially 25-30kt S of cape
charles). Seas build to 3-4ft sat, 5-7ft sun, and potentially 6-10ft
by mon. This will likely result in an elevated risk of rip currents
next week.

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.
