Synopsis
High pressure track east across the western atlantic, while low
pressure over the southern states works northward through the
middle of the week. The low will lift across the area on
Wednesday and Wednesday night, exiting to the north on Thursday.

High pressure returns Thursday night with a wave of low
pressure passing near the area on Friday and Friday night. A
weak frontal system on then moves through on Saturday followed
by sprawling high pressure building in early next week.

Near term until 6 am Tuesday morning
Main change this update was to lower temperatures over the pine
barrens - adjusted towards cooler ecs guidance. Otherwise, only
minor changes were made with this update to reflect the latest
trends in observations and guidance. The forecast in all other
respects appears on track.

Upper air pattern features a southern branch closed low working
slowly east across the tennessee valley, and an upper ridge
moving off the eastern seaboard.

Conditions will remain dry and just below seasonable levels for
overnight lows. Used a blend of the MOS with slight adjustments
outside of the pine barrens. High level cloudiness ahead of the
low will very slowly work northeast. Depending on how fast the
clouds and low level moisture come in could result in some
locations cooling more quickly than others with some patchy fog
as well.

Short term 6 am Tuesday morning through Wednesday
Models are in good overall agreement in taking low pressure
over the tennessee valley northeast through Wednesday, taking
the low near or just west of nyc late Wednesday. The ECMWF is on
the slower side of the guidance.

Clouds will overspread the area from the SW during the day with
light overrunning rains developing from west to east in the
evening and becoming steadier overnight. A strong low-level jet
will enhance warm advection rains toward daybreak, with the
possibility of a thunderstorm during the morning and afternoon
hours. The coverage will diminish in the afternoon and may
become more convective in nature. Instability aloft though is
marginal and not surface-based.

Rainfall totals will be highest from nyc and points north and
west due to orographic enhancement with a modest SE flow. Gusts
up to 30 mph will be possible along the coast. Amounts will
range form 0.75 inches far eastern areas to 1.25 in the hills
north and west of nyc. Should the upper trough become more
negatively tilted than forecast, these amounts will likely need
to be increased due to more offshore convection and warm
conveyor belts rains working into the region
highs on Tuesday will be a bit cooler due to the cloud cover
and onshore flow, but will be milder Tuesday night for the same
reason. Highs on Wednesday will be similar.

Long term Wednesday night through Monday
There are some differences in the upper pattern right out of
the long term gate Wed night that continue through the remainder
of the period. The general h5 flow consists of troughing over
eastern north america giving way to western ridging during the
second half of the weekend or early next week.

Models begin with differences in location of the upper low,
ec cmc the slowest moving with the nam GFS the fastest. Given
the scenario, have sided with the slower moving, and thus have
pops continuing bust decreasing Wed night. A wave of low pres
tracks through or near the nyc metro area Wed night with a
temporary lull in winds during the eve. This combined with a
s-se flow could keep areas of fog around into the eve, but since
winds will be shifting to the s-sw, have only gone patchy attm.

Elevated instability also appears to be present during the eve,
although its marginal so have included schc thunder.

A few areas of rain may linger into thu, especially across
northern zones, otherwise dry weather returns into Fri with weak
sfc ridging building in.

A shortwave trough tracking through the plains midweek tracks
through the SE states Thu and up the east coast on fri. All nwp,
except the GFS keeps pcpn offshore, although 12z cmc and ec have
trended westward. Pcpn remains east of the area, but is closer,
thus have schc-chc pops in the forecast to account for this.

High uncertainty with a potential frontal system impacting the
area on sat. GFS is less amplified aloft, keeping energy
associated with trough axis well to the N while cmc ec are
sharper cut off at h5. Have gone with consensus for the time
being with a schc-chc pops. Deep layered ridging then builds in
behind this resulting in dry and warm weather into next week.

Near to slightly above normal temps are expected through the
period.

Aviation 03z Tuesday through Saturday
High pressure will continue move off the coast into Tuesday
afternoon. Low pressure approaches from the southwest Tuesday
night.

Se flow under 10 kt will continue at city terminals tonight with
light and variable elsewhere.

Se winds increase on Tuesday to 10-15 kt. A few gusts 15 to 20 kt
are possible in the late morning and afternoon. Winds back towards
the E Tuesday evening.

Vfr through 00z Wednesday with MVFR developing in -ra 00z-06z
Wednesday.

Outlook for 00z Wednesday through Saturday
Tuesday night Rain developing with lowering flight categories to
ifr, potentially lifr overnight. E to SE winds may gust to around
20 kt near the coast.

Wednesday Rain with ifr lifr conds. Isolated thunderstorm
possible. SE winds 15-20, gusting 25-30 kt.

Thursday Shower possible with conditions becomingVFR.

-Friday-Saturday... MainlyVFR. Chance of showers late Friday
into Saturday.

Marine
Minor changes were made with this update to reflect the latest
trends in observations and guidance. The forecast appears on
track.

A light pressure gradient over the waters will limit winds to 10
kt or less through Tuesday morning. The gradient increases
Tuesday afternoon, with winds up to around 15 kt forecast over
the waters.

A small craft advisory (sca) has been issued for the ocean
waters Tuesday night into Wednesday and will likely need to be
extended into Wednesday night for lingering high seas.

Conditions are marginal for the bays, harbor, and sound.

Low pressure moving up the eastern seaboard Tuesday into
Wednesday will result in strengthening easterly winds and
building seas Tuesday night. Winds likely subside below sca
Wednesday evening as low pressure moves to the north.

An inversion over the waters is expected to keep higher winds
aloft Wed night. However, SCA seas will likely linger on the
ocean waters into Fri before subsiding. Sub advsy conds are then
expected on all waters for the rest of the forecast period.

Hydrology
A widespread 3 4 to 1 1 4 inches of rain is likely Tuesday
night into Wednesday, with heaviest amounts favored across nyc
metro, NE nj, lower hudson valley, and SW ct. Minor urban and
poor drainage flooding is possible if high end of rainfall
ranges are realized.

Equipment
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air.

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.
