Synopsis
High pressure builds southwest of the region tonight, moving to
the south of the region and eventually offshore Monday into
Monday night. High pressure departs to the east Tuesday,
followed by a cold front Wednesday. Another high builds late
week before next system impacts the area next weekend.

Near term until 6 am Monday morning
The polar upper level jet will be south of the region. In the
mid levels, a trough axis moves through the region bringing its
associated vorticity maxima with it. This upper level
disturbance will enhance lift and with the leftover moisture,
could result in a few snow showers with the continued cold air
advection. Snow showers are the precip type due to wet bulb
cooling. With limits in low level moisture and not much QPF from
numerical model guidance, left as slight chance.

At the surface, high pressure will build to the southwest of the
region. The parent low attached to the cold front that moved
across earlier will continue to deepen as it heads into eastern
quebec. This will keep a steep pressure gradient within the
region.

Concerning winds, they will remain gusty out of the west but
will be lowering in magnitude as the boundary layer winds are
expected to lower. The decrease of temperature at the surface
especially with the periods where there are fewer clouds will
allow for surface to lower in temperature more, disrupting the
vertical mixing and allowing for gusts to become infrequent.

Wind advisory was not extended into the evening as winds in the
3-8kft layer show remarkable decrease more towards 30-35 kt
going through the evening, making for less wind to mix down.

This was conveyed with both NAM and GFS bufkit soundings. Lows
were a blend of mav ecs as met numbers seemed too high.

Short term 6 am Monday morning through Monday night
The region is more in between the polar and subtropical upper
level jets. In the mid levels, more of a ridging trend will take
shape. At the surface, high pressure moves eastward towards the
carolina coastline Monday and then off into the atlantic Monday
night.

Dry conditions are expected through the period. Monday is
expected to be cooler, about 5 degrees below normal with more
gusty wnw flow, mitigating sensible heat transfer.

For Monday night, winds are expected to lower with gusts
diminishing. With mostly clear conditions, expect radiational
cooling to result in a more typical vast range of lows between
the urban heat island and inland rural sections.

Long term Tuesday through Sunday
Better model agreement today in this active and progressive pattern.

Aloft, active northern stream expected as multiple shortwaves pass
during this time frame.

Looks like the operational GFS has now trended much closer to other
global models with handling of mid week trough. Latest GFS is
notably weaker with trough along the gulf states Wednesday, and is
thus not developing a wave of low pressure off the coast Thursday,
like it did 24 hours ago.

As such, looks like WAA on the backside of the high will provide a
mild breezy day Tuesday, likely the warmest of this time frame.

Plenty of Sun will give way to increasing clouds as high level
moisture approaches, along with moisture advecting from the south in
the lower and mid levels. NAM wrf seems to be the most aggressive in
outputting precip ahead of the cold front. Still looks like best
chance for rain will be east of nyc late Tuesday into Wednesday.

Dry thereafter as ridge builds. A cold front passes with little
fanfare Friday, then next shortwave approaches this weekend. Colder
air advects in behind a front by Sunday. Minimal pops warranted next
weekend with this system.

Above normal temps Tuesday in WAA regime, then temps tumble to just
below normal from late Wednesday through Sunday. Looks like a cool
day Thursday, with a slight rebound Friday and Saturday before
falling back again Sunday. A model MOS blend followed which is in
line with latest wpc numbers.

Aviation 21z Sunday through Friday
High pressure builds in through tonight.

Vfr. Wnw sustained winds 20-25 kt with frequent gusts around 30 kt
and occasional gusts around 35 kt through 23z. Winds then back
slightly by about 10-20 degrees this evening with sustained winds
around 15 kt along with gusts 20-25 kt.

Outlook for 18z Monday through Friday
Monday Vfr. W-nw winds g20-25kt. Gusts diminish gradually at
night.

Tuesday MainlyVFR. MVFR possible late Tuesday night in showers.

Sw winds g20-25kt.

Wednesday MVFR possible with showers during the day.VFR at
night. NW winds g20kt in the aftn evening.

Thursday-Friday Vfr.

Marine
Steep pressure gradient remains tonight, so still expecting
gales for all waters tonight. Winds will be getting closer to
35kt through the night as boundary layer flow decreases. The
boundary layer flow further decreases Monday with gales becoming
marginal. SCA will then be more likely across the waters on
Monday especially the ocean with high seas of 5-8 feet
continuing. SCA conditions still probable for the ocean Monday
night while non-ocean waters will see an eventual decrease in
wind gusts to below SCA late.

Winds increase in SW flow Tuesday. A few locations could
approach gale force or 35 kt. Winds then diminish somewhat
Tuesday night ahead of a cold front. Low pressure passes
southeast of the waters Wednesday as the cold front crosses the
area. NW flow Wed night back to the west and diminishes further
Thursday as a ridge of high pressure builds. A cold front passes
Friday, with the ridge building back yet again.

Hydrology
No hydrologic problems are anticipated.

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.
