Synopsis
High pressure builds to the north through the weekend, and across
the canadian maritimes early next week. Low pressure may pass south
and east of the local area through the middle of next week, followed
by a slow moving cold front during the second half of the week.

Near term until 6 pm this evening
Forecast remains on track. Just minor updates to current
temperatures and dewpoints with this early afternoon forecast.

Otherwise, high pressure builds to the north today. With a
significantly drier airmass in place, this should result in
mostly sunny and pleasant conditions with just a few fair
weather clouds. Highs will range from the mid 70s to around 80.

Short term 6 pm this evening through 6 pm Sunday
High pressure settles over maine Saturday night, allowing east to
northeast flow to become established across the region. While
Saturday night is expected to remain dry, clouds will begin to
increase as the low levels moisten. By Sunday morning, light rain
and drizzle is possible, primarily across coastal areas. While an
increase in cloud cover is expected farther inland across northeast
new jersey and the lower hudson valley, conditions there should
generally remain dry.

High temperatures on Sunday are expected to remain several degrees
below normal for late august, only topping out in the mid 70s.

There is a moderate risk of rip current development at atlantic
ocean beaches on Sunday.

Long term Sunday night through Saturday
As the high gradually drifts to the east, light rain and or drizzle
could linger into Sunday night for some locations, with clouds
lingering into the day on Monday under persistent east to northeast
flow.

Attention then turns to the potential for tropical development off
the southeast coast and a slow moving cold front that approaches the
region during the mid to late week period. At this time, any
potential tropical system would bring mainly indirect impacts to the
region as global models continue to be in good agreement with this
system passing well south and east of the area. For the local area,
this could result in the potential for coastal flooding and
dangerous rip currents, depending on the exact strength and track of
the system. See the tides and coastal flooding section for more
details on the coastal flood potential.

A cold front then approaches the region late Wednesday, moving
slowly through the area on Thursday. While differences remain,
models are in much better agreement with respect to the timing of
this system than 24 hours ago. High pressure builds in for Thursday
night into Friday.

After below normal temperatures again on Monday, near normal
temperatures are expected through the remainder of the long term
period, with highs generally in the lower 80s and overnight lows
falling into the mid 60s to around 70.

Aviation 18z Saturday through Wednesday
High pressure builds over northern new england this weekend.

MainlyVFR is expected through the TAF period. There could be
some sprinkles or periods of light rain on sun, with a low
probability that ceilings could drop to MVFR.

Winds become NE around 10 kt this afternoon. There is a low
chance for a SE sea breeze at jfk, isp, bdr and gon in the late
afternoon or early evening. NE winds continue tonight and sun.

Outlook for 18z Sunday through Thursday
Rest of Sun Low probability of MVFR. Sprinkles or periods of
light rain possible. NE winds 10-20 kt along the coast.

Mon Vfr. NE gusts 20 kt along the coast.

Tue Vfr.

Wed MVFR possible. Showers and thunderstorms possible.

Thu Vfr.

Marine
A prolonged period of SCA conditions is possible Sunday into
the middle of the next week. Initially, with high pressure to
the north strong northeasterly flow sets up Sunday into Monday,
with gusts of 25-30 kt on the ocean and seas building to 4 to 6
ft. Waves are then likely to remain above 5 ft on the ocean
waters through the mid-week period as a tropical cyclone
potentially develops and tracks south and east of the waters.

Wave heights and wind gusts remain uncertain at this time due to
the uncertainty in the exact track and strength of the storm.

Hydrology
No hydrologic impacts are anticipated through the middle of next
week.

Tides coastal flooding
A prolonged period of easterly flow will increase tide levels over
the next several days. Localized minor coastal flooding is possible
with Monday and Tuesday afternoon evening high tides along the south
shore back bays of queens and nassau counties.

Equipment
Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.

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.
