Synopsis
A frontal boundary remains stalled to the south of the region with
high pressure to the northeast. A trough of low pressure will
develop to the west on Sunday followed by a weak cold front Monday
night. This boundary dissipates over the area on Tuesday, although
another cold front approaches Wednesday and moves through Wednesday
night. High pressure then builds in for the remainder of the
week.

Near term through tonight
No significant changes to the forecast from the earlier package.

Temperatures are a few degrees warmer, so have updated based on
the latest observations. In general, low clouds across the
region will dissipate through the morning. With ample moisture
across the region, clouds may be slower to scatter than
yesterday, becoming partly sunny by mid afternoon.

Otherwise a similar pattern remains in place with another shortwave
triggering a few showers or thunderstorms this afternoon, mainly
across the interior where there will be greater instability and mid
level forcing.

Temperatures will be in the low to mid 80s, however if areas get
more Sun than forecast, temperatures will rise a few degrees
warmer. A light onshore flow will keep temperatures cooler along
the coast.

There is a moderate risk for the development of rip currents at
atlantic ocean beaches today.

Short term Sunday through Sunday night
A stationary front will remain just to the south of the region for
the second half of the weekend with high pressure building to the
south and west. This will result in a hot and humid air mass
building into the start of next week, as southwest flow returns. On
Sunday, temperatures across northeast nj will touch 90 with highs
across nyc metro in the upper 80s, with cooler temps along the
coast. MAX heat index values will be in the a few degrees higher
than the air temperature.

Scattered showers and thunderstorms may develop once again Sunday
afternoon as a trough sets up west of nyc. Overnight low
temperatures will be in the in the low to mid 70s, which is
about 5 to 7 degrees above normal.

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

Long term Monday through Friday
Hot, humid and somewhat unsettled weather will continue for the
first half of next week. Nwp is in good agreement with the overall
upper pattern across north america during the long term period, with
bermuda high pressure remaining in place resulting in gradually
rising heights rising across the northeast into early next week.

Currently, the hottest day appears to be Monday with widespread
upper 80s to lower 90s, mid 90s in urban NE nj. Dewpoints in the 70s
will yield heat index values in the mid to upper 90s, possibly
reaching 100 in NE nj. With heat index values forecast to remain
below 95 both Sunday and Tuesday, it looks that we will remain below
heat advisory criteria, but it will be something to watch with
subsequent updates.

A weak cold front approaching on Mon could then trigger isolated
showers storms Mon aftn eve. This boundary moves into the area mon
night so have kept the low chc during this time although tstms may
be nil.

It dissipates over the area on Tue although a shortwave lifting up
the east coast and a digging trough to the west is expected to
trigger additional showers and tstms on wed. The former piece of
energy may pass far enough east to keep that activity offshore, but
pre-frontal convection is possible during the aftn eve. This
stronger front moves through Wed night bringing and end to the
showers tstms and a more comfortable airmass as high pres builds
from the great lakes through fri. Temps are expected to be near to
slightly below normal levels Thu and fri.

Aviation 12z Saturday through Wednesday
High pressure east of the new england coast will remain in
control through the weekend. This will keep the area in a
prolonged period of E SE flow.

MVFR ifr conditions will prevail for the morning. Timing of
improvement is uncertain, and these conditions may persist longer
than forecast. Webcams show some scattering in the nyc area,
but visible satellite imagery and area obs show stratus in
general holding firm. Stratus will likely be quickest to clear
from kewr kteb and kswf, but slower for terminals to the east.

MVFR ifr will redevelop tonight, but exact timing of lowering
conditions is also uncertain.

Similar to the previous few days, an isolated shower or thunderstorm
is not out of the question with the best chance being north and west
of the nyc terminals. There is a low chance of a shower or
thunderstorm developing within n90 airspace. Winds mostly light ne-e
this morning becoming e-se 5-10 kt by afternoon.

Outlook for 12z Sunday through Wednesday
Sunday Chance of mainly afternoon and evening showers and
thunderstorms. Best chance north and west of the nyc terminals.

MVFR ifr ceilings improving through the morning.

Monday MainlyVFR. Slight chance shower or thunderstorm.

Tuesday-Wednesday MainlyVFR. Chance showers or
thunderstorms.

Marine
A generally weak pressure gradient will keep seas below 5 ft into
the early week. Winds and ocean seas then begin to increase by
Wednesday in advance of a cold front, with seas reaching SCA levels
by Wednesday night.

Hydrology
No hydrologic impacts are expected at this time through the forecast
period.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
