Synopsis
High pressure builds in from the west through tonight, before
retreating into new england Thursday. An area of low pressure
will develop over the tennessee valley Thursday, with a second
area of low pressure moving up the east coast Thursday night.

The low will likely pass just east of montauk early Friday,
then into the canadian maritimes Friday night. A broad area of
high pressure builds in for the weekend.

Near term through today
A deep layer northern stream ridge builds over the area
overnight. While associated subsidence under the ridge will keep
things dry, will see high clouds increase overnight per latest
satellite trends.

Still appear on track for a freeze across nyc (except staten
island) - the only locations in the CWA yet to experience a
freeze this fall - so left freeze warning for there as is.

Lows will be unseasonably cold, in the low teens across the
northern zones and low 20s along the coast.

Short term tonight through 6 pm Friday
The next impactful storm system will move into the region on
Thursday bringing our first good bout of snow chances for the
season. The low pressure tracking north up the east coast will
bring a slug of moisture and gusty winds starting by mid-day
Thursday. The timing of the system looks to bring the initial
round of precip as snow to much of the region by mid day.

Heaviest snowfall is expected along the coast during the first
few hours of the afternoon, generally between 1 and 4 pm before
switching over to rain as warmer air intrudes. This transition
from snow to rain will begin along the coast nyc and move inland
through the evening, with some sleet or freezing rain possible
during the transition as well. As for snowfall amounts, for the
nyc long island area expecting a slushy inch or two, with more
accumulation likely on grassy surfaces. Meanwhile, areas along
the coast can expect 1-3 inches with 2-4 inches further inland.

Given these amounts and the fact that this is our first real
winter system of the season, a winter weather advisory has been
issued Thursday afternoon night for much of the region,
excluding long island and the nyc metro. Ice accretion to around
a quarter inch is possible in the hudson valley where the
predominant ely flow will likely remain backed further to the
north. Temperatures during the day reach the low 30s inland and
the mid to upper 30s elsewhere.

Model agreement is fairly good in placing the low center over
the south central nj coast by early Friday morning. As it
approaches and deepens, the surface pressure gradient tightens
significantly while at the same time a good LLJ moves over the
coast. This will mean gusty winds Thursday night into Friday,
especially along the coast.

Long term Friday night through Wednesday
The precipitation winds down Friday and winds decrease as the
low moves off and our pressure gradient relaxes. Under zonal
flow aloft and a building surface high, the weather should be
dry and quiet late Friday and Saturday. Low chcs for pcpn on sun
thru Mon with a frontal system potentially impacting the area.

There remain some significant timing and track differences
between the GFS and ecmwf, so a blended approach was used for
the fcst. The model consensus was for dry weather on Tuesday and
Wednesday.

Aviation 06z Thursday through Monday
High pressure builds in from the west early this morning before
retreating into new england later today. Low pressure then
approaches the area this afternoon and crosses the area
overnight into Friday morning.

Vfr conditions through the morning with nne winds becoming ene
at 5-10 kt.

Conditions then lower to MVFR, then ifr, this afternoon as
precipitation overspreads the terminals area between 18-20z. For
the city and coastal terminals, other than initial burst of
snow at onset, precipitation should generally begin as a
snow sleet mix before changing to a mix of rain and sleet, then
ultimately to all rain. This transition will occur fastest at
the city and long island terminals, where all rain is expected
by about 00z. For the lower hudson valley terminals,
precipitation is expected to begin as snow before transitioning
first to a mix of snow and sleet, then to a period of freezing
rain between 22-02z. Frozen freezing precipitation will linger
the longest at kswf, which has the potential to see an 8-12 hour
period of freezing rain beginning tonight and lasting into
Friday morning.

Ene winds will become gusty late this afternoon into the
overnight hours, with gusts of 30-35 kts at coastal terminals
and gusts gusts of 25-30 kts elsewhere. Gusts should begin to
subside towards 12z as winds begin to shift back to the nw.

Outlook for 06z Friday through Monday
Late tonight-Friday morning MVFR or lower conditions likely
with gusty ene winds 25-35kt, especially at city and coastal
terminals. Lingering wintry mix at kswf, otherwise all
precipitation remains rain before tapering off by midday.

Friday afternoon BecomingVFR. N-nw winds gusting g20-30kt.

Friday night-Sunday Vfr. NW winds g15-20kt possible.

Sunday night-Monday MVFR or lower possible in possible rain
or wintry mix.

Marine
Tranquil conditions with a relaxed pressure gradient into
Thursday morning, give way to small craft advisory (sca)
conditions by Thursday afternoon ahead of an advancing coastal
low. Should then see gales on all waters Thursday night and
quite probably through Friday. Conditions will likely then remain
at SCA levels through Friday night. Winds will be below sca
levels over the weekend, but seas will only slowly subside to
below 5 ft on the ocean thru Saturday. A frontal system could
produce SCA conditions Sunday night and Monday, mainly on the
ocean.

Hydrology
Liquid equivalent QPF of .75-1.5 inches expected mainly from
midday Thu til midday fri. A good deal of this should fall as
snow and then freezing rain across the interior. Nuisance
ponding urban flooding possible in the nyc metro area and across
long island.

No hydrologic impacts are expected sat- tue.

Tides coastal flooding
Despite the large departures of around 3 ft needed, minor tidal
flooding is still possible during the early Fri mrng high tide
cycle, particularly over the east end of li, the vulnerable back
bays of LI and nyc, and perhaps a few spots along the WRN sound.

Equipment
Nyc NOAA weather radio station kwo35 (162.55 mhz) will remain off
the air for an extended period of time.
