Area Forecast Discussion
National Weather Service New York NY
1249 AM EST Sat Feb 17 2018

.SYNOPSIS...
High pressure builds into the region through early Saturday,
before sliding off the New England coast Saturday afternoon. A
developing low pressure system Saturday will track to the Mid-
Atlantic coast Saturday evening and then southeast of Long
Island overnight Saturday into early Sunday. Low pressure then
departs as high pressure passes to the southeast early next
week. A warm front lifts northward, then a cold front passes
late in the week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
High, and mid and upper level ridging, is now building to the
west. Surface pressure gradient will be weakening along with
cold advection. Winds and gusts diminishing, especially
overnight. Drier air continues to move in quicker than expected
with dew points inland into the teens. Clouds have moved south
of Long Island and updated sky conditions.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Saturday will feature ridge axis moving offshore Saturday with
a farther northward movement of the upper level jet streak. High
pressure at the surface will center across the region Saturday
morning before moving off the New England coast in the
afternoon. The NW flow decreases with winds eventually swinging
around to become E-SE. Daytime mixing will favors a little warm
air advection in the afternoon with low level veering of winds.

Now the focus will be Saturday night with track, magnitude and
precipitation with a coastal low pressure area tracking
southeast of Long Island. The upper level jet is shown by models
to be quasi-zonal, SW to NE orientation, which will match the
track of the low.

This low pressure system initially was developing today in SW
Pacific and this will have tracked through South Central US
through Tennessee Saturday. From there, it heads ENE into the
Mid-Atlantic Saturday evening and then deepens off the coast of
the Delmarva by late Saturday night. It takes a track to the SE
of the 40N/70W benchmark with boundary layer temperatures and
the magnitude of deepening of the low crucial to the amounts of
snow. The deeper the low, the more dynamic cooling there will be
and this goes with the intensity of the snow as well. It's a
positive feedback loop, heavier snow would also force colder air
to the surface. The timing of this event Saturday night leans
more towards a colder solution compared if this were to occur
during the day.

Models have trended a little farther south with the low
pressure center and without a large pressure gradient between
the departing high and the approaching low, lowered snow amounts
by around an inch. Also on this side of a slight decrease will
be marginal boundary layer conditions at onset of snow. The
temperatures will be slightly above freezing and unless the snow
is quite intense, it will take an hour or so to decrease the
surface temperature to wet bulb temperature. So for first 1-2
hours, snow may not accumulate much. Looking at a general 9pm to
3am timeframe for much of the snow to fall.

Still see potential for banding with the snow with 1 inch per
hour snowfall amounts possible, so 4-6 inch snow amounts
forecast but with locally higher amounts possible. Where this
streak of higher amounts occurs is quite uncertain at this time
and that is why the winter storm watch was maintained and it
can't be ruled out over Orange and Putnam New York, so watch was
expanded to those counties as well. Some higher snow
accumulation in the 6 to 8 inch range was shown in the latest
SREF but there are members on the lower end showing a few inches
as well. Snow rapidly trends down from west to east early
Sunday.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Deep west/southwesterly flow aloft backs as western trough digs
and eastern ridge builds early to mid week. The ridge flattens
slightly late in the week as heights aloft fall.

At the sfc, low pressure departs as high pressure quickly
builds and passes offshore. A warm front passes to the north
Monday, and the local area remains firmly in the warm sector
Monday night through Wednesday.

A cold front passes sometime Wednesday night or early Thursday,
then high pressure builds to the north Friday. Global models
appear to be in general agreement.

As for sensible weather, dry conditions are anticipated Sunday,
then rain accompanies the warm front Monday. While the area is
in the warms sector, hit or miss light rain or drizzle is
possible, as is nighttime and morning fog.

Some rain may accompany the cold front Wed night, with another
warm front approaching Friday.

Temps rebound right away Sunday, then rise further Monday
through Wednesday. There will be quite a temp difference west of
the Hudson river (warmer), and along the south facing coasts
(much cooler) as you would expect this time of year.
Temperatures cool slightly behind the front Thursday into
Friday.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
VFR into this afternoon with high pressure building over the
terminals. Conditions will begin to deteriorate after 00z.

NW winds 10-15 kt will continue early this morning. There could be
occasional gusts to around 20 kt until 09z. Winds continue
diminishing after day break as they veer to the NE and then SE in
the afternoon.

A rain/snow mix develops around 00z transitioning to all snow 02-
04z. The snow should gradually taper off from west to east early
Sunday morning. Snowfall accumulations of 4 to 6 inches are
forecast.

.OUTLOOK FOR 06Z SUNDAY THROUGH WEDNESDAY...
.Tonight...LIFR/IFR in snow.
.Sunday...VFR.
.Monday...VFR becomes MVFR or IFR in rain and possible fog,
especially late.
.Tuesday...MVFR or IFR possible in the morning and again at night,
otherwise VFR with SW wind G20KT possible.
.Wednesday...Mainly VFR. Chance of showers/MVFR.

&&

.MARINE...
Minor changes to the winds and gusts. Seas, winds and gusts have
all increased as cold advection of the waters increased,
especially the ocean. Timing on the ending of the SCA on the
none ocean waters should still be around 06Z and cold advection
and the surface pressure gradient will be diminishing after 04Z.
Ocean seas will remain near 5 ft much of tonight.

The coastal low tracking southeast of Long Island will be weak
in magnitude so winds are not expected to increase much Saturday
night, keeping conditions below SCA.

NW winds initially Sunday behind low pressure will back around to
the south as high pressure builds and passes offshore. The
south/southwesterly pressure gradient tightens Monday and Tuesday,
and winds will begin to increase during this timeframe.

Tranquil seas Sunday and Monday begin to build as the southerly
winds pick up in speed. Expect 5 ft seas by Tuesday on the ocean
waters.

&&

.HYDROLOGY...
Around 0.3 to 0.6 of an inch of liquid equivalent is expected
Saturday night with locally higher amounts. With most, if not
all of this falling in the form of snow, no hydrologic impacts
are expected.

No significant hydrologic impacts are expected Sunday through the
end of next week.

.EQUIPMENT...
NYC NOAA Weather Radio Station KWO-35 (162.55 MHz) is off the
air for an extended period of time.
