Synopsis
High pressure passes to the north tonight. Attention then turns
to a significant winter storm that will impact the region late
Saturday into Sunday as a low pressure system moves up the
coast. Low pressure deepens as it moves into the canadian
maritimes Sunday night. Arctic high pressure then builds in for
early in the week, eventually moving offshore Tuesday night.

Another low pressure system approaches from the south and west
Wednesday and its associated frontal boundary may stall nearby
Thursday into Thursday night. The weather pattern remains
unsettled for the end of the week with high pressure staying
well north of the region.

Near term until 6 am Saturday morning
Flat upper flow prevails ahead of trough that tracks out of the
rockies tonight. At the surface, weak low pressure departs, and high
pressure builds to the north.

Any lingering clouds will give way to mainly clear skies overnight
as temperatures fall into the 20s, except lower 30s in and around
nyc metro.

Short term 6 am Saturday morning through Sunday
A significant winter storm is still expected to impact the area this
weekend.

Changes to the headlines... A winter storm warning is now in
effect for portions of northeastern nj, the lower hudson valley
and for extreme western ct. A winter storm watch remains in
effect for the remainder of the forecast area, with the
exception of coastal suffolk county and the twin forks of long
island.

The eventual development and track of the surface low will depend
largely on the timing of phasing between a vorticity maximum
rotating around a broader hudson bay low pressure system, and a low
pressure trough that will gradually move into the pacific
northwest tonight. Ideally as the system moves onshore, a
better sampling of 00z and 12z raobs into tomorrow morning will
aid in the overall model consensus of its downstream
implications.

As of now, there unfortunately remains a fair amount of uncertainty
with regard to the eventual track of the surface low and expected
thermal profiles precipitation types. The onset of precipitation has
trended slightly faster in recent model runs, so expect light snow
to overspread the region from west to east by late Saturday
afternoon into the evening. Confidence is high that the initial
precipitation type will be all snow, as temperatures largely remain
below freezing. For locations that are marginally above freezing, a
dry subcloud layer will aid in evaporative cooling that will allow
precipitation type to remain all snow.

Light snow will be short-lived, as the phasing of the troughs aloft
leads to strengthening low level winds and warm advection after
midnight. A corridor of intense frontogenesis is expected to rotate
through the region, quickly aiding in increasing precipitation
rates. Confidence is highest that the interior - mainly where
the winter storm warning is now in effect, will remain snow
longest. Elsewhere confidence is lower. The operational NAM and
3 km NAM remain the coldest, with cold air damming persisting
longest, but are outliers compared to other deterministic
forecasts. However, there is a tendency for cold air to remain
longer than forecast. The GFS has continued in its past couple
runs to phase the upper systems faster, resulting in a continued
northward trend with the surface low placement. Should the gfs
verify, a quicker onset to rain will occur, with substantially
lower snow and ice amounts. The other available guidance is
largely in the middle of the two, including the 12z euro. The
current forecast remains a good compromise between all the
aforementioned scenarios, so little change was made, though it
should be noted that overall a slight trend towards warmer
solutions may be favored, with a transition to rain along
coastal locales occurring between around 2-6 am Saturday
night Sunday morning.

Of significant concern, however, is the potential of at least a few
hours of sleet and or freezing rain across the interior, given
the impressive low-level warm advection. If the colder solution
of the NAM verifies, the depth of the cold air beneath the warm
layer would favor more of a sleet profile. Being a high qpf
event, there is potential that accumulations may be significant.

The most likely corridor for this occurrence will be southern
portions of the lower hudson valley, northeastern nj and parts
of western connecticut. Additionally, should the colder (more
nam-based) solution verify, then there's potential that
sleet ice accumulations may be as far south as the nyc metro.

Further trends will need to be monitored closely. Per earlier
coordination with surrounding offices and wpc, a more
conservative approach was taken with the forecast with no major
changes made at this time.

Previous analogs of similar events lend confidence towards at least
a narrow region with sleet ice potential, with the closest match
being february 2, 2015. Ice accumulations for that event were up to
a quarter of an inch, which is in line with our forecasts for this
event, and snow accumulations were primarily 6 to 14 inches, with
highest amounts across the interior.

Also similar to the 2015 event, deterministic models reflect a final
low level vorticity maximum moving through from west to east as the
system departs by early Sunday afternoon, which may be sufficient
for a quick few additional inches of snow as temperatures across
remaining areas quickly fall to below freezing once again. Cold
advection will then be strong into the evening, with the potential
that any standing water on untreated surfaces could quickly freeze,
creating hazardous travel conditions even where little wintry
precipitation occurs.

Long term Sunday night through Friday
Arctic airmass builds in behind departing low which will be heading
into the canadian maritimes Sunday night. The arctic high pressure
moves in for Monday and Tuesday before moving offshore. Cyclonic
flow aloft with upper level low moving in Sunday night into Monday.

The coldest and most frigid air takes hold of the region Sunday
night through Monday night with a moderation of the airmass
thereafter with more ridging aloft.

A low pressure system moves in for Wednesday into Thursday timeframe
with perhaps a stalled front nearby. Aloft, a large longwave trough
develops west of the region. Unsettled weather then remains with low
pressure not that far away and high pressure well to the north of
the region for the end of next week with a deep trough still
remaining aloft in the northeast.

Flash freeze continuing into Sunday evening. Sunday evening starts
well below freezing for the entire region with lows by early Monday
expected to be the coldest thus far experienced this season with
most locations having forecast min temperatures from 0 to 10. Gusty
nw winds will help advect in a significantly colder airmass with
subzero wind chills Sunday night into Monday. Gusts are forecast to
reach up to 35 to 40 mph. These gusts could even reach 45 mph at
times on Monday.

Potential for wind chill advisory criteria to be met mainly for
locations north and west of nyc (wind chills of -15 to -20) for
Sunday night into early Monday and for a small part of the interior
(parts of western passaic nj, orange ny, putnam ny, northern
fairfield ct) for wind chills near -15 for late Monday night into
early Tuesday.

Then, another system approaching from the south and west could give
the next wintry precipitation to the region. A lot of uncertainty
exists with this system and model depictions of its evolution and
track. There is the possibility of snow changing to a wintry mix for
mainly interior and western parts of the region Tuesday night into
early Wednesday as well as Wednesday night into early Thursday for
far interior locations. Another chance of snow for Thursday night
into Friday of next week. This will all be tied to the evolution and
progress of a low pressure system and associated front.

Aviation 20z Friday through Wednesday
Low pressure pulls away as high pressure builds tonight. The
high gives way to a warm front late Saturday.

MVFR ceilings will scatter this evening.VFR conditions
expected overnight and through Saturday morning.

Light winds become S sw, then west into this evening. Then winds
shift further to the NW north later tonight.

Ne winds increase to around 10 kt late Saturday morning.

Ny metro enhanced aviation weather support...
