Synopsis
A cold front will move slowly east across the area late tonight,
then stall just east of long island on Saturday. High pressure
will follow Saturday night through Tuesday. A cold front will
pass across the area Wednesday night followed by high pressure.

Near term until 11 pm this evening
Severe thunderstorm watch in effect for portions of
northeast nj... Southeast ny... Nyc... Western long island and
western ct through 9 pm...

damaging wind gusts are possible with any thunderstorm that
develops through 9 pm as they approach from the west.

In addition to the severe weather threat, the threat of flash
flooding remains high due to a combination of earlier rainfall
of up to 4 inches in some areas, anomalously high dew points and
precipitable water values up to 2.2 inches. As such, a flash
flood watch was issued for NE nj, the metro nj nyc area,
including rockland, westchester, and nassau counties in ny and
southern fairfield county in ct until 11 pm this evening with
the expectation that showers and thunderstorms will increase
ahead of the cold front.

Satellite imagery shows a SW NE dry slot advecting NE across ne
nj. This will increase sfc based and low lvl instability
resulting in the development of organized convection mainly aft
20z this afternoon from SW to ne.

There is a moderate risk of rip currents at ocean beaches,
potentially becoming high this afternoon.

Short term 11 pm this evening through Saturday night
Leftover showers and tstms will end with the passage of the cold
front between 06z and 12z overnight. With light winds forecast
during this time, areas of fog will develop, possibly dense
across long island and southern ct.

With a digging upstream trough approaching Saturday, the cold
front may not make it too far off the long island coast. In
fact, it's possible that it might retrograde a bit until the
passage of this trough Saturday night.

Dryer air will advect east across the area Saturday night as
high pressure advects east toward the area.

Long term Sunday through Friday
A broad area of high pres will build in Sun and mon. This will
produce seasonable temps and mostly clear skies. A thermal ridge
will build into the region Tue into wed, producing a mini heat
wave. Some spots, particularly across nern nj, may hit the 2 day
heat advy criteria. As subtropical moisture becomes entrained
in the flow, an increase in high clouds can be expected by wed.

The cold frontal timing has slowed slightly from the previous
12z model suite, so right now the timing is for the late aftn
and eve. Although the best chance for tstms will be with the
fropa wed, there will be chances prior, albeit lower, due to the
unstable airmass and onset of lowering heights. Because of the
progged position of the front and tendency of the guidance to
smooth out the temp gradient, highs were manually raised on wed.

A significant cool down then looks to follow for the end of the
week. The models have been very consistent with this signal,
although the exact magnitude of the cold airmass remains in
question. It would not be totally surprising to see some lows in
the furthest outlying areas touch the upr 40s next weekend.

Aviation 20z Friday through Wednesday
A cold front slowly approaches the region this evening but lags
nearby until early Saturday.

Showers and thunderstorms cross all the nyc terminals between 21z
and 01z. What is left of the line will be east of kisp and kgon by
04-05z. Any storm may contain gusty winds and torrential rain.

MVFR ifr lifr ceilings are likely with the convection. Little or no
improvement is expected overnight since overall conditions will
remain saturated and fog and stratus are likely to continue or
redevelop.VFR returns Saturday morning as drier air works into the
region.

Southerly winds this afternoon, mainly between 10 to 15 kts. Gusts
to 25 kt possible along the coast. Higher gusts possible with any
thunderstorm. Winds become west and eventually northwest early
Saturday but remain light.

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.
