Synopsis
A cold front across the eastern great lakes slowly moves
southeast, toward the region, overnight. The cold front then
crosses the area Saturday into Saturday night. A series of lows
along the cold front south of long island will keep the frontal
boundary not too far away for the close of the weekend into
early next week. Meanwhile, high pressure from the canadian
maritimes will begin building down along the northeastern
seaboard. High pressure gets closer to the local region Monday
into Tuesday next week. A frontal system from the west moves
across Wednesday into Wednesday night with high pressure
returning thereafter.

Near term until 6 am Saturday morning
The severe thunderstorm watch was cancelled as the line of
thunderstorms moving through eastern nj has weakened, with the
storms encountering somewhat more stable air as the gust front
moves out ahead of the line. Some gusty winds and heavy
rainfall will be possible with some of the stronger storms with
special weather statements possible. Surface instability and
cape to 2000 j kg remain across the eastern zones.

A warm and humid airmass remains, with dew points still in the
lower to mid 70s, with some locations in the upper 70s, as the
cold front was still well to the northwest.

Will keep likely and chance probabilities as the upper shortwave
and impulses will be moving into the region overnight.

Short term 6 am Saturday morning through Saturday night
The old front will be very slow to push southward across the
area. Some additional showers and thunderstorms are possible
Saturday as the upper trough axis remains to the west, through
upstate ny and into the ohio valley. Instability looks limited
lowering the potential for severe thunderstorm development,
precipitable waters will remain above normal and as a result any
thunderstorms that do development have the potential for heavy
downpours.

Temperatures on Saturday will be in the mid to upper 80s with
heat indices remaining below heat advisory criteria.

There is a low risk for the development of rip currents at the
atlantic ocean beaches Saturday.

Long term Sunday through Friday
Cooler and a little less humid conditions expected to start out
Sunday through Monday with more rain in the forecast Sunday and
Sunday night as the region gets more NE flow. Airmass warms up
for mid to late in the week, near normal levels with winds
having more westerly and southerly components.

Upper level trough will be slow to exist for the close of the
weekend. Trough axis will be west of the region Sunday and
Sunday night with jet streak across the region. The trough axis
moves across Monday. The steering flow will not promote the
front to move farther south of long island and with weak low
pressure areas forming along it, essentially keeping some rain
showers in the forecast for the region, highest chances along
the coast.

More drying takes place Monday when more ridging aloft and high
pressure at the surface will settle more southwestward along
the northeastern seaboard. Dry conditions remain until midweek
when the next frontal system approaches from the west. Aloft, a
large amplitude trough will be approaching with a stronger
southerly jet ahead of it. This jet moves in Wednesday night
into early Thursday. Chances for showers return Tuesday
afternoon and Tuesday night with highest chances N W of nyc. The
chances for showers continues Wednesday with thunderstorms
possible as well as instability is forecast to increase again
with the airmass getting warmer and more humid. Dry conditions
return Thursday into Friday next week with high pressure
returning.

Aviation 03z Saturday through Wednesday
Generally,VFR through the TAF period, except MVFR or lower in
any showers and thunderstorms.

Showers and thunderstorms have weakened as they move across the
metro terminals. However, there continues to be isolated
lightning strikes. Additionally, there is another developing
area of showers and thunderstorms across northern new jersey
that will likely affect the metro terminals, so vcts was added
through 05z. Thereafter, conditions may actually be dry for a
period until Saturday morning, though the chance still exists
for showers and thunderstorms.

Winds S to SW tonight will shift to the SW to W late sat
morning into the afternoon as a cold front moves through.

Outlook for 00z Sunday through Tuesday
Sat night Scattered showers tstms. W flow becoming NE sat
eve.

Sun Potential for MVFR conditions in shra and NE winds of
8-12kt.

Mon-tue Vfr.

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

Marine
Winds and seas remain below SCA levels overnight through
Saturday night across the forecast waters. Showers and
thunderstorms will continue to move through the area waters
overnight, and some gusty winds will be possible early,
especially across the western waters.

Sca conditions are possible on the ocean waters Sunday. Some
marginal SCA wind gusts are possible for non-ocean waters with
otherwise sub SCA conditions expected for all non-ocean 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.

Hydrology
Thunderstorms, with heavy to torrential rainfall, through
Saturday could result in minor urban flooding. There is also an
isolated flash flood threat with the strongest thunderstorms.

No significant widespread rainfall expected during the long
term.

Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.

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.
