early Sunday afternoon.
&&
.KEY MESSAGES...

2) An Arctic cold front will bring light snow accumulation

and hazardous/dangerous wind chills through the weekend.
3) Temperatures moderate from Sunday through Thursday.

.DISCUSSION...
.KEY MESSAGE 1...
High pressure west of the region will settle over the area
today, then weaken as offshore low pressure passes well SE.
Temperatures will remain close to 10 degrees below normal.
.KEY MESSAGE 2...
A strong cold front will approach tonight and move across on
Saturday. Some snow will accompany the front. Any snow will
generally be light in nature, with 1-2 inches expected, with the
highest amounts further east.
The more impactful weather will be the cold air and strong
winds, leading to potentially dangerous wind chills late day
Saturday into Saturday night. Stayed fairly close to the
previous forecast winds and gusts which were adjusted toward
higher NBM percentiles and MOS, while NBM temperatures looked
reasonable. Winds will be reach or come close to reaching
advisory criteria Sat into Sat evening. Expect sustained 25-35
mph with gusts 45-50 mph possible over a good portion of the
area (especially NYC metro and along the coast). Held off on any
wind headlines at this time. Winds will not be quite as strong
late Sat night into early Sunday morning, still sustained at
10-20 mph. Combined with low temps 0 to 5 below well inland and
in the single digits elsewhere, wind chills late Saturday night
into early Sunday morning will be as low as 20-25 below well
inland, 15-20 below most elsewhere, and 10-15 below in NYC and
the immediate surrounding east/west suburbs. Have issued an Extreme
Cold Watch for the entire region for Saturday night into early
Sunday afternoon.
.KEY MESSAGE 3...
With strong cold advection continuing (as seen with veering
winds in forecast soundings) on Sunday and 850 mb temperatures
ranging from - 14 to -22 C on Sunday, temperatures are not
expected to rise above the teens. With breezy conditions; a NW
flow of 10 to 20 mph and gusts of 20 to 30 mph, wind chill
values will be as low as -10 to - 25, with the coldest readings
well north and west of NYC, across the Lower Hudson Valley and
inland CT.
Moderation in temperature is expected through the week as Arctic
high pressure weakens over the region and upper level ridging
from the upper Mid-West tries to makes its way into the area.
The upper ridge weakens as it approaches, so although it is
expected to warm up, temperatures will still be below normal
through the period. By Thursday, temperatures will be in the
middle to upper 30s, while normals are around 40, so it will be
seasonably cool.
.KEY MESSAGE 4...
The next chance for precipitation will be Wednesday into
Thursday as a frontal system approaches. Right now, thermal
profiles support snow to rain or a rain/snow mix at times,
depending on exact placement of frontal systems and subsequent
development of any low pressure systems.
&&
.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
Low pressure and an associated Arctic cold front will approach
today and tonight, and pass through early Saturday.
VFR conditions through this afternoon, then periods of snow
developing with IFR vsby tonight.
Light N winds become variable or SSW this afternoon/evening.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
There is the potential that MVFR cigs could develop this
afternoon before snow arrives.
.OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY...
Late tonight: IFR at times in snow. NW winds gusting at or above
20 kt late.
Saturday: MVFR/IFR in snow, mainly east of the NYC metro
terminals. Lower chances of snow by afternoon. VFR returns by
later Saturday afternoon into Saturday night. NW winds 20-30 kt
with gusts 35-45 kt, highest afternoon into early evening.
Winds gradually diminish thereafter.
Sunday: VFR. NW winds 10-15 kt with gusts 20-30 kt.
Monday and Tuesday: VFR.

forecasts, can be found at: https:/www.weather.gov/zny/n90

.MARINE...
After quiet conditions, NW winds increase to gale force
following an Arctic cold frontal passage on Saturday. Peak gusts
are expected to reach 40-45 kt. Due to cold air/water temps
and strong winds, moderate to heavy freezing spray is also
possible during this time frame.
Gales likely continue on all waters Sunday morning, with winds
diminishing through the day. A conversion to SCA is expected by
the afternoon, then SCA`s come down for the non-ocean waters by
Sunday night. SCA`s likely remain in place for the ocean waters
as seas 5-9 ft on Sunday diminish to 4-6 ft Sunday night, and
remain at or above 5 ft through Monday morning. SCA cond may
persist into Monday night E of Fire Island Inlet.
