338 pm edt Thu mar 21 2019

Synopsis
A cold front will cross the area tonight. Another mainly dry cold
front will move through Friday evening. High pressure will then
build into the area this weekend. A storm system is expected to
impact the region early to mid next week.

Near term until 6 am Friday morning
As of 925 pm thu... Widespread low clouds associated with low
pressure over southeast virginia are starting to scour out in
response to convective mixing and westerly low level flow.

These clouds are forecast to dissipate by 00z this evening. This
evening the axis of a strong mid level trough will pivot
through the region after midnight. As this system approaches it
will trigger scattered shower activity through about 9z then dry
advection will occur as the flow becomes NW behind a cold
front. This will end the shower activity and cause skies to
clear before sunrise. Lows will be in the low to mid 40s inland
and mid to upper 40s coast.

Short term 6 am Friday morning through 6 pm Friday
As of 3 pm thu... It will become windy Friday afternoon as a cold
front approaches late. Skies will start off clear but could see
some increase in clouds late afternoon, especially northern
locations. Not out of the question that a few showers or
sprinkles develop northeast zones late as the front begins to
move into the area, but decided to keep the forecast dry for now
due to strong downslope flow that will have to be overcome. West
winds will gust to 35 mph at times Friday afternoon ahead of the
front. Highs will be in the low to mid 60s.

Long term Friday night through Thursday
As of 315 pm thu... Rising heights aloft and developing mid to
upper level downsloping flow will keep deep subsidence and a dry
forecast in place Friday night. At the surface, a moisture-
starved reinforcing cold front will approach from the northwest,
crossing the area in the evening. Breezy conditions will
develop behind the front, especially for coastal areas, as winds
shift from west to northwest. Lows will drop into the mid to
upper 30s Friday night as low level CAA fills in behind the cold
front. Winds are expected to remain elevated enough overnight
to preclude any significant frost threat.

Saturday and Sunday... Deep layer subsidence prevails Saturday
through Sunday - keeping sunny clear conditions in place. Cool
high pressure builds in from the west Saturday, bringing
decreasing winds and below normal temps, before passing
overhead and offshore Sunday. Many locations away from the
immediate coast will see freezing temperatures, or at least
frost, Sunday morning given the cool airmass in place and light
winds clear skies efficient radiation expected. Frost freeze
headlines are likely given that the growing season has begun.

Monday through mid-week... Unsettled weather is expected early
next week, with global guidance in much better agreement than
24 hours ago. In general, an upper trough is expected to dig
across the eastern us Monday into Tuesday, developing low
pressure across the midwest and moving it to sc on Tuesday, then
off the southeast coast Wednesday. Locally, the cold front
associated with this system is the dominate feature for bringing
precip, with the greatest shower chances arriving in the warm
sector ahead of the front Monday night into Tuesday. The front
should move through the area during the day Tuesday, with high
pressure building in behind it Wednesday. However, there are
indications that low pressure could develop along the front off
the coast and move northeast, justifying slight chance pops
along the immediate coast Wednesday. Temps will be above normal
ahead of the cold front, and below normal behind the cold front.

Aviation 19z Thursday through Tuesday
Short term through Friday ...

as of 7 pm thu... Widespread MVFR ceilings occurring across the
taf sites late this afternoon should dissipate or improve toVFR
by 00z this evening. Scattered showers are forecast to develop
this evening ahead of a strong mid level trough 0-6z and could
produce brief subVFR conditions. Dry advection after 6z will
lead to clearing skies behind a cold front late tonight through
much of Friday. Winds are expected to become gusty out of the
west, especially after 15z Fri when gusts to 30 kt are expected.

Long term Friday night through Tuesday ...

as of 315 pm thu...VFR conditions will prevail through Sunday.

A cold front will approach from the west early next week, and
increasing moisture ahead of the front will bring the potential
for at least periods of flight restrictions beginning Monday
morning.

Marine
Short term through Friday ...

as of 925 pm thu... Gusty winds and elevated seas necessitating
long fused small craft advisories will continue through Friday
as a series of cold fronts cross the waters. The first front
will cross tonight with W flow 15-25 kt becoming NW after
midnight. Friday winds will back to W 15-25 kt ahead of an
approaching cold front. 7-11 ft seas this evening will subside
to 5 to 8 ft Friday.

Long term Friday night through Tuesday ...

as of 315 pm thu... A dry cold front will cross the waters later
in the day on Friday, bringing a surge of northwest winds
Friday night into Saturday. The SCA for the coastal waters
remains in effect into Saturday to cover this, and additionally
scas for the sounds and possibly rivers may be needed as well.

Given that the winds are offshore, seas will continue to
gradually subside nearshore despite continued breezy conditions,
while beyond 10 nm offshore seas will remain around 5-8 ft into
the day Saturday.

Later Saturday, high pressure crossing the region will bring
improving marine conditions, as winds and seas subside through
Sunday morning. Then, late Sunday, the high will move offshore
and southerly winds will develop, steady increasing through
early week ahead of a strong cold front approaching from the
west.

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.
