Synopsis
A cold front approaches tonight and passes through Wednesday
morning. High pressure then dominates the weather pattern from
Wednesday afternoon into early next week.

Near term until 6 am Wednesday morning
Forecast is on track with some minor changes made to reflect
current conditions. Earlier this afternoon, 2 lines of
convection were moving toward the area, with some of the
thunderstorms becoming severe. A fair amount of weakening has
occurred with these lines over the last couple of hours and
much of the dynamics to support severe thunderstorms have pushed
well north of the tri- state. Also, the 2 lines have become one
larger area of showers and thunderstorms, with a more
stratiform look to it over central pennsylvania. Cloud top
warming is also noted in the ir. With that said, there still is
a chance for some of the storms that form ahead of this main
area to become strong to severe, with the main threat being
damaging winds in the strongest storms.

A severe thunderstorm watch has been issued for passaic, orange,
and putnam counties until midnight tonight.

A pre-frontal trough and cold front move in from the west. Showers
and thunderstorms are expected with both boundaries. CAPE and shear
values are sufficient for strong storms with gusty winds. Some
of these storms may become severe, with damaging winds being the
main threat across passaic, orange, and putnam counties and a
severe thunderstorm watch has been issued until midnight tonight
for these areas. Better chances for the stronger gusts would be
along the pre- frontal trough as CAPE will be greater during
the evening hours. The trailing cold front will have less cape
to work with during the overnight hours, but winds aloft may
still allow for strong gusts.

The steering flow should be quick enough to mitigate chances of
flash flooding and training of cells is not expected to be a factor,
but with high moisture content around, minor nuisance urbanized
flooding is possible.

A high rip current risk remains in effect into tonight.

Short term 6 am Wednesday morning through 6 pm Wednesday
The cold front will be right over the tri state area at the start of
Wednesday morning and should be east of montauk by late morning.

Still cannot rule out a lingering shower or thunderstorm mainly east
of the city in the morning. Much drier air then filters in behind
the cold front for the afternoon with mostly sunny conditions. It
will start to feel less muggy as well, and highs will be in the
lower and mid 80s. Mainly clear for Wednesday night. Low
temperatures across the northernmost suburbs and the pine barrens
region are expected to drop into the mid 50s.

There is a moderate rip current risk for Wednesday.

Long term Wednesday night through Tuesday
A mainly quiet weather pattern takes shape in the long term as
canadian high pressure will dominate with below normal temperatures
and mainly dry conditions.

Anomalous longwave trough will be swinging across the eastern states
on Thursday, with a vigorous piece of energy trailing behind the
main trough axis. This energy is progged to dive towards the region
Thursday night into early Friday morning at the same time of some
upper jet support. While ensemble members and deterministic runs are
dry with this feature, there is enough lift and brief moisture
return to warrant a low chance pop for showers. The shortwave energy
shifts offshore Friday morning, with the main upper trough lingering
just to the east through the weekend with tranquil conditions. The
surface high settles over the northeast for the weekend, then
centers itself off the new england coast early next week as ridging
builds aloft.

850 temperature anomalies will run 3-6c below normal into the
weekend. This will result in surface temperatures running several
degrees below normal. Forecast highs may be warmest on Thursday, in
the upper 70s and low 80s, and then run in the middle and upper 70s
through Sunday. A more easterly flow sets up early next week which
should help keep highs below normal. Nighttime temperatures will
range from the lower 50s inland to the lower 60s near the coast.

Aviation 00z Wednesday through Sunday
A cold front approaches the region late today and crosses tonight.

South southwest winds will remain gusty into the evening push. Gusts
of 20 to 25 knots expected, with occasional higher gusts possible
along the coastal terminals.

A line of showers thunderstorms will track across central ny pa
this evening. Majority of hi-res guidance, including last
several runs of hrrr, is indicating weakening, with stronger
looking storms passing to the n, as they approach nyc nj
terminals between 04z and 07z. Due to this, have not included a
tempo in the 21z TAF amendments as confidence is not high enough
for it or a prevailing vcts and prob30 can no longer be used.

Not completely ruled out, still a 20-30% chance at the metro
terminals. Confidence slightly higher to the n, thus have
maintained mention at kswf khpn. Gusty winds and MVFR possible
in any stronger thunderstorm. This activity slowly moves through
the area overnight. MVFR to ifr conds may redevelop persist
especially at kbdr kisp kgon until cold FROPA passes.

Northwest flow may be just strong enough to preclude seabreeze
development Wed aftn. Otherwise...VFR.

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.
