Synopsis
High pressure continues to move offshore today, allowing low
pressure to approach from the west, passing just north of the
area tonight. Meanwhile, a developing coastal low will develop
and pass just east of montauk during the day Wednesday, then
moves up the coast into the canadian maritimes Wednesday night.

High pressure will then build to the south through Friday,
moving into the western atlantic this weekend. Low pressure will
then approach from the west early next week.

Near term until 6 pm this evening
High pressure continues to push offshore today. This will allow
and low pressure system and associated cold front to approach
from the west. 00z forecast model guidance in fairly good
agreement keeping much of the region dry today. The only
exception will be late this afternoon where some light snow may
develop, as low pressure approaches. Any precipitation will be
light and limited to just the far northwestern portion of the
cwa. As such, have backed up the start time of the winter
weather advisory for portions of nj and the lower hudson valley
til 4pm. Otherwise, expect cloudy skies today. Temperatures
today climb into the lower and middle 30s. Expect the lower 30s
across the interior, and the middle 30s, closer to the coast.

Short term 6 pm this evening through 6 pm Wednesday
Winter weather advisories in effect for northeast new jersey,
the lower hudson valley, southern connecticut and the northern
portion of nyc for late this afternoon through Wednesday.

Low pressure and associated cold front approach the western
portion of the CWA tonight, with the low passing just north of
the region. Meanwhile, a second area of low pressure develops
south of long island tonight, and passes east of montauk early
Wednesday afternoon. The combination of these two system will
bring precipitation to the region. Highest confidence of snow is
north and west of nyc, while the potential for mixed p-types
reduces confidence for the city into long island and coastal
connecticut. Expecting the precipitation to remain mostly all
snow through midnight, then as the developing low approaches, it
should bring some warmer air into the area to change
precipitation over to rain or a rain snow mix across much the
long island, nyc and portion of coastal ct. The changing p-type
has made forecasting snowfall amounts somewhat difficult,
especially right along the rain snow line. For now, thinking the
highest snowfall totals will be across the lower hudson valley
and southern ct, with the exception of southern new london
county. These areas have 4-6 inches of snow forecast. Across ne
nj and the northern portions of nyc, looking at 3-4 inches. The
southern portion of nyc and nassau, 2-3 inches are expected. And
across suffolk county on long island, up to 1 inch. The
heaviest precipitation is expected to fall Tuesday night into
Wednesday morning, then taper off from west to east during the
mid to late afternoon and early evening.

Lows tonight fall into the middle and upper 20s across the
interior, while coastal locations fall into the lower 30s. On
Wednesday, highs climb into the lower 30s across the interior,
with middle 30s closer to the coast.

Long term Wednesday night through Monday
On the heels of an upper trough passing offshore early Thursday, a
progressive southern branch of the polar jet will become dominant
across the lower 48, with a a gradual warmup as the air mass
transitions to pacific origin. Daytime highs on Thursday will be or
just above near freezing, rising to the upper 40s and lower 50s by
Sunday Monday.

Conditions will be mainly dry as a large area of high pressure over
the lower mississippi valley translates slowly east and passes to
the south through the week and offshore this weekend.

A southern branch storm system then approaches late in the weekend
into early next week, with a surface low forecast to track up into
the great lakes. The trailing cold front moves through Monday night.

This is likely to be a rain event with a deep layered southerly flow
preceding the system, but with cold sfc air initially there could be
some mixed precip inland late Sunday night Monday morning inland nw
of nyc.

Aviation 09z Tuesday through Saturday
High pressure retreats to the northeast today. An area of low
pressure approaches from the south into tonight.

Mainly MVFR to get started, with some low endVFR ceilings at kteb
and kgon to get started, with those two terminals becoming MVFR by
14z.

For the most part expect any precipitation to hold off until after
sunset, except at kswf where could see some light snow in the
afternoon. Currently only expecting ifr conditions at kswf through
6z Wednesday. Expect all snow at lower hudson valley and nj
terminals and kbdr. Will see a snow rain mix at kgon kisp and
possibly a rain mixing in with the snow at klga and kjfk through 6z
tonight.
