Synopsis
A cold front will continue to slowly sink south of long island
through early next weak as a series of weak low pressure waves
travel along the frontal boundary. Meanwhile, a high pressure
ridge will extend southwest from new england Monday into Tuesday
while weak low pressure passes to the south. A cold front will
move across on Wednesday, followed by high pressure to close the
week.

Near term until 6 am Sunday morning
The cold front has pushed south of the area, and along with it
the convection. Therefore, have taken any mention of thunder
out. Most recent guidance has the tri-state mainly dry,
however, there is an area of showers over central new
jersey. Therefore, went with just a chance for showers mainly
for long island, new york city, and portions of northeast new
jersey, with slight chance north of these areas.

A weak shortwave trough, axis over central ny, will remain
fairly stationary into tonight. At the surface, a weak frontal
boundary gust front is pushing south of long island as of 730
pm, with a broken line of showers and thunderstorms pushing
offshore.

There is a low potential that locally heavy shower and embedded
thunderstorm activity could re-develop late tonight into sun
morning across LI nyc (along elevated instability gradient) as
trough axis approaches and weak low pressure tracks south of the
region.

A bit cooler and drier air works into the region late tonight
with lows in the upper 60s to lower 70s.

There is allow to moderate risk of rip current development into
this evening due to 3 ft southerly wind waves.

Short term 6 am Sunday morning through Sunday night
The weak upper trough axis will slowly slide east across the
region Sunday into Sunday night. Meanwhile at the surface, the
cold front to the south of LI will continue to slowly sink
farther south, as canadian maritimes high pressure builds down
through new england.

Morning shower activity, particularly across nj, nyc and li,
should gradually push south from north to south in the afternoon
as the front sinks farther south. There is low potential that
this activity could be locally heavy with embedded thunderstorms
(along elevated instability gradient) as trough axis approaches
and weak low pressure tracks south of the region.

Otherwise, considerable cloud cover is expected on Sunday with
the upper trough moving through and low- level inversion in the
canadian maritimes NE flow regime. With abundant cloud cover
and breezy maritime NE flow (gusts 20 to 25 mph along the coast)
on Sunday it will be comparatively chilly compared to the last
several weeks, with temperatures running several degrees below
normal on Sunday, generally lower to mid 70s.

Canadian maritimes high pressure will remain in control Sunday
night, with generally dry and seasonably mild conditions, but
stratus likely remaining stubborn across much of the region.

There is a moderate to high risk of rip current longshore
current development on Sunday, due to 5 ft easterly wind wave
combined with 2 ft southerly swells.

Long term Monday through Saturday
Dur to the proximity of sfc low pressure just south and a weak upper
low moving across, will hold onto slight chance pop Mon morning,
also slight to low chance pop on tue. With the approach passage of a
more significant upper trough and associated cold Tue night into
wed, will see likely pop late Tue night and possibly into wed
morning. See hydrology section for further details, as there could
be some urban and flash flood potential, impacting the Wed am rush
if current model timing holds.

With mid level confluence behind this departing trough on Thu and
then ridging aloft Fri into sat, sfc high pressure should then
follow, with a noticeably drier air mass moving in on Thu with
dewpoints in the 50s and remaining into Saturday.

Except for Tue night Wed when temps may be a few deg above avg,
expect temps right near seasonal averages.

Aviation 03z Sunday through Thursday
Generally,VFR through about 07z with n-ne winds. Thereafter,
MVFR CIGS move in on the NE flow and will linger into Sunday
afternoon. Some terminals could see stratus move in earlier,
such as klga and kbdr as they were reporting MVFR CIGS as of
03z.

An area of showers is approaching the city terminals
from central new jersey, but they are weakening as they
approach. No thunder is associated with these showers.

N-ne winds are expected tonight into Sunday, with sustained
winds of 15 kt or lower.

Outlook for 00z Monday through Thursday
Sun night-tue Vfr.

Tue night-wed Chance of shower TSTM with MVFR conds.

Thu Vfr.

Marine
Winds and seas remain below SCA levels through midnight across
the forecast waters as a weak cold front moves through, but any
showers and thunderstorms moving across the waters will be
capable of producing gale wind gusts and reduced visibilities
in heavy rain.

Ne gradient tightens tonight in wake of cold front, with sca
conditions expected to develop on the ocean waters, E LI sound,
and peconic and gardiners bays late tonight and continue
through Sunday. Marginal SCA wind gusts are likely for the
remainder of near shore waters.

Then, sub-sca conditions are expected for all the forecast
waters early into the middle of next week but there is a
possibility the SCA seas could linger into Monday for the ocean.

Ocean seas could reach SCA criteria again Wednesday night into
Thursday.

Ocean seas out east may build to SCA levels of at least 5 ft on wed
ahead of an approaching cold front. These elevated seas may linger
into Wed night.

Hydrology
Flash flood threat has ended for this evening.

There is a low potential for minor urban and poor drainage
flooding late tonight into Sunday morning across nyc LI with
some guidance indicating heavy showers and perhaps embedded
thunderstorms developing along an elevated instability gradient
to the north of a surface low.

Tuesday night into Wednesday... Showers tstms with heavy rain
may be possible with a passing frontal system. With low areal
ffg especially over NE nj, pw increasing to well over 2 inches,
and deep layer SW flow indicative of potential training of
cells, there is some urban and flash flood potential in this
time frame from nyc north west.

the air for an extended period of time.

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.
