Synopsis
A cold front over southern canada will drift south through the
tri-state region on Saturday. An unsettled weather pattern
continues Sunday into the middle of next week. Cold front to our
south returns to the region Sunday night into Monday and moves
offshore Monday night. Another frontal system approaches on
Tuesday and moves across Tuesday night into Wednesday. High
pressure returns Thursday ahead of the next front on Friday.

Near term /until 6 am Saturday morning/
The rain has ended across the region this afternoon as the bulk
of the theta-e advection has occurred.

Some moisture around 6000 ft remains tonight, but there is no
lift in that moist layer. Despite some colder cloud tops on
infrared satellite over pennsylvania, there is no rainfall
occurring. With the models supporting a dry forecast through the
overnight as well, the weather has been kept dry.

A broad blend of the model data has been used for temperatures,
with mild readings expected due to southwesterly flow and cloud
cover.

Short term /6 am Saturday morning through Saturday night/
A cold front over southern ontario will track south through the
area by late Saturday morning into the afternoon. The timing is
pretty consistent between the NAM and gfs, so the NAM was used
in the grids. This translates into falling temperatures across
the northern half of the forecast area by afternoon, with the
fall in temperatures later in the day across new jersey zones.

Water vapor indicates a moisture stream from the subtropical
pacific into the southeastern united states. This will allow for
some deeper moisture to penetrate into the region during the day
and through the night. The upper jet will be passing from
southern canada into northern new england at this time,
producing some broad lift. With these factors combining, light
rain has been forecast for the area mainly Saturday afternoon
and Saturday night. Easterly component low level flow could
allow for some fog or drizzle development particularly
overnight. Patchy fog has been maintained in the forecast along
with the light rain as a result.

The downscaled NAM was used for temperatures Saturday to account
for the cold frontal passage. A blend of guidance was used
Saturday night.

There is a low chance that temperatures approach freezing late
Saturday night which could result in some pockets of interior
icing. The probability is low at this time, so it has not been
included in this forecast.

Long term /Sunday through Friday/
Unsettled, progressive weather pattern will persist from Sunday
through the upcoming week. Deterministic models and ensembles are in
general agreement with the synoptic scale, with differences arising
in the timing and amplitude of several shortwaves to move across.

Backdoor front will be well to the south on Sunday with high
pressure building south of out of quebec. Warm air overrunning the
stable, cool layer at the surface will keep low clouds throughout
the day and the chance for light rain or drizzle.

Upper level ridging will be in place, so there is not much support
for widespread precipitation. Temperatures will be held down in the
lower and middle 40s due to onshore flow and cloudy conditions.

Cutoff low over the central states on Sunday will open and lift
towards the great lakes Sunday night and then continue to dampen out
as it moves towards the region on Monday. Upper ridge axis gradually
moves offshore allowing for better lift for more widespread
rainfall. Pops increase to likely for much of the area late Sunday
night into Monday morning with categorical across the north closer
to the shortwave energy and best lift.

Shortwave axis quickly moves east Monday afternoon and evening,
which will take the lingering front to the south and east.

Brief ridging moves across Monday night with another shortwave on
its heels for Tuesday. This is where deterministic runs and
ensembles begin to diverge further as the latest 12z ECMWF flattens
this next shortwave out as it passes whereas the 12z GFS and the
gefs are more amplified, bringing a weak low pressure across the
region. Have capped pops off in the chance range due to the
uncertainty on the amplitude of this wave. In either case, mostly
cloudy to overcast skies continue.

An amplifying shortwave across southeast canada sends a shortwave
across new england on Wednesday, but frontal boundary should be well
offshore at this time, so improving conditions are expected. High
pressure than follows on Thursday before another frontal system
approaches for Friday.

Near seasonable temperatures are forecast on Monday with
temperatures returning to above normal levels Tuesday into
Wednesday. Seasonable temperatures are currently expected for the
end of the week.

Aviation /20z Friday through Wednesday/
A cold front will cross the region Saturday.

MainlyVFR through late tonight but there's a low chance of
MVFR or lower at coastal terminals late. By midday Saturday,
the front approaches and then passes through with low clouds and
some drizzle developing. Conditions deteriorating to MVFR and
then ifr during the midday and afternoon hours. Lifr is
possible.

S-ssw winds this afternoon 10-20 kt with gusts to 25 kt. Good
chance of gusts to near 30 kt at kisp and kjfk. Winds diminish
this evening. On Saturday, winds near 15 kt veer to NW and then ne
Saturday afternoon as the front moves through.

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.
