Synopsis
High pressure builds southwest of the region tonight, 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
Upper trough axis will swing across the region tonight.

Vorticity MAX within the trough could enhance lift just enough
to produce an isolated rain or snow shower, mainly N and W of
nyc. Have left pop as slight chance, but adjusted to better
match latest trends in observations.

At the surface, high pressure will build to the southwest of
the region. Winds will remain gusty out of the wnw, but will be
lowering in magnitude as mixing weakens through the night.

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 03z Monday through Friday
Vfr as high pressure builds in through Monday.

Wnw winds continue tonight. Gusts 20-25 kt may be intermittent
at times. An isolated rain or snow shower possible mainly NW of
nyc terminals.

Gusty w-wnw winds around 25 kt expected on Monday.

Outlook for 00z Tuesday through Friday
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 afternoon evening.

Thursday-Friday Vfr.

Marine
Steep pressure gradient remains tonight, so still expecting
gales for all waters tonight. Wind gusts closer to 35 kt are
forecast 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.

No hydrologic problems are anticipated.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
