Synopsis
High pressure moves offshore this afternoon. A deep low passing
several hundred miles west then north of the region will
produce unsettled weather tonight and Sunday. Mainly fair
weather is expected next week, with a low potential for both a
midweek system and an end of the week coastal low.

Near term until 6 pm this evening
The forecast through this early this evening remains on track.

Water vapor continues to indicates a stream of moisture pumping
directly into the area from the subtropical pacific. The goes-
east channel 4 (cirrus band) really shows the extent of the
cirrus really well. While there are thin spots, a mostly cloudy
characteristic fits what is being observed on satellite. The
cirrus will only thicken through the day in this pattern.

The forecast remains dry today as high pressure slowly drifts
offshore. Middle and upper level ridge axis overhead will also
help in keeping any precipitation with the approaching system
well to our south and west.

Highs will be near or slightly below average in the lower to
middle 40s.

Short term 6 pm this evening through 6 pm Sunday
The main challenge tngt, outside of timing the exact onset of pcpn,
is the fzra threat across the interior. Temps aloft will warm
quickly, but very lgt sely flow will likely not be sufficient to
displace the llvl cold air across the interior. Regardless, the
entire airmass should modify enough to change all pcpn across the
area to plain rain by around 10-12z sun.

For the fcst, a model blend of the 2m data minus one degree was used
for temps. The resultant temps are right around freezing across the
interior, so any deviations of a degree or two from the fcst will
result in as little as no fzra, or a more extensive area of fzra.

A winter wx advy has been issued for orange county, where the prob
of fzra is highest. Some pockets of fzra are possible from nwrn nj
zones to interior ct zones. These areas have some fzra included in
the fcst, along with a mention in the hwo. These areas could be
upgraded to an advy if necessary based on future data. Across the
rest of the area, all rain is expected.

The rain tapers off from SW to NE during the day on sun. Again, the
trend is slower, so ERN sections could see rain for most of the day.

The nbm was used for temps, with the guidance remaining consistently
mild for the day.

For winds, pres gradient begins to tighten late tonight between
departing high pres and strong low pres moving into the great
lakes. Winds will start to increase late tonight and continue
through sun, although low level inversion is expected to keep
much of the winds from mixing down until the cold FROPA late sun
aftn eve.

Long term Sunday night through Saturday
The cold front associated with the sys comes thru Sun eve, right
around 00z per the GFS and nam. Persistent dpva could help to
trigger a few shsn Sun ngt and even mon, but moisture is limited.

The fcst was kept dry for now with the deepest moisture N of the
cwa.

For winds, guidance has been overdoing wind events all season.

Additionally, highest pressure rises behind the FROPA are
expected to be across southern nj. Therefore, while winds are
expected to be strong, am not confident enough to issue a high
wind watch at this time. Current thinking is a strong wind
advsy. Anticipating sustained winds between 25-35 mph with gusts
40-50mph, possibly 55mph with the strongest winds occurring on
Monday. Winds then gradually decrease Mon night.

Mainly fair and seasonably cold wx is then fcst for the rest of the
week. The GFS has backed off on the sys for wed, and the ECMWF and
gem are both dry. As a result, pops were reduced to 20 percent.

There are some hints of a cstl sys for the end of the week or next
weekend time period. A model blend was used with pops limited to
slight chance Fri and Fri ngt.

Aviation 18z Saturday through Thursday
High pressure moves off into the atlantic through tonight to
southeast of nova scotia. Low pressure system approaches from
the west with its warm front approaching the region tonight and
moving across on Sunday.

Vfr into much of this evening. Initially some very light rain
develops for nyc terminals and terminals to the north and west
with higher decks of clouds around 8-10kft around 03z Sunday.

Rain becomes heavier and more steadier overnight into early
Sunday with conditions deteriorating to ifr lifr. Exact timing
of categorical changes could be a few hours off from taf.

Winds become SE 5-10 kt this afternoon and then more easterly
tonight with nearly the same speed. Winds become more SE again
overnight into Sunday at 10-15 kt. There will be llws
developing with SE winds of 40-45 kt at 2kft from 09-17z.

Outlook for 12z Sunday through Wednesday
Sunday MVFR ifr during the afternoon behind warm fropa, then
vfr late behind cold fropa.

Sunday night Vfr. W winds 15-25kt with g35-40kt.

Monday Vfr. W-nw winds 25-30kt with gusts near 50kt. Winds
decrease significantly at night.

Tuesday Vfr. NW winds 10-15 kt with g20kt.

Wednesday Possible light snow with possible MVFR local ifr.

Marine
High pressure over the northeast shifts offshore this aftn and
tonight as low pressure in the central plains tracks NE towards the
great lakes while strengthening. The pres gradient will tighten late
tonight with SCA conds developing on the ocean waters by sun
morning. A warm front will lift into the waters during the morning,
with a cold front passing late Sun aftn and eve. Winds will
strengthen to gale force Sun eve with possibly even storm force
gusts on the ocean waters late Sun night through mon. The strongest
winds and highest seas will be during this time. Winds and seas
gradually diminish Mon night and Tue although headlines will likely
be needed through this time.

Sub-advsy conds are then expected through the remainder of the
forecast period.

Hydrology
Around 1-1.5 inches of rain is fcst tngt and sun. Some minor urban
or poor drainage flooding will be possible. Otherwise, no hydrologic
impacts are anticipated thru fri.

Equipment
Nyc central park winds are out of service until further notice.

Loss of data is due to a severed cable. Parts are on order.

Nyc NOAA weather radio station kwo35 (162.55 mhz) will remain 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.
