.SYNOPSIS...
High pressure remains in control through tonight. A cold front
will pass through Thursday afternoon, followed quickly by another
strong high pressure system building from the west Thursday night
into Friday. Weak low pressure passes off the southern Mid
Atlantic coast Friday night into Saturday. Brief high pressure
Saturday night into Sunday gives way to another cold front passage
Sunday night. High pressure will then be in control early next
week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
High pressure in place gradually weakens tonight.

Lows overnight will again drop below freezing, near 32 in NYC,
upper 20s at the rest of the coast then into the mid to lower
20s in interior locations. Despite freezing temperatures
anticipated, black ice is not a major concern. Any lingering wet
surfaces that froze over this morning, should be dry tonight.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY NIGHT/...
Key Points:

* Cold frontal passage will usher in a quick shot of very cold air
  Thursday night into Friday.

* Weak low pressure passing well south may brush the area with
  some light snow/rain Friday night.

NBM brings the cold front through dry Thu afternoon, but some
CAMs have a hints of precip with the front. Its likely it will
remain a dry frontal passage with low PWATs in place, but the
strong forcing could lead to a few flurries N & W of NYC
Thursday afternoon. Max temperatures on Thursday should reach
the upper 30s to lower 40s prior to the cold front`s arrival.
Streamers from the Great Lakes following the frontal passage are
unlikely to make it into the area Thursday evening, but still
something worth monitoring.

A gusty NW flow will usher in very cold air for Thu night into
Fri, with low temps from the lower 20s in NYC, to the teens most
elsewhere, to some single digits well inland, with wind chills
as low as the single digits inland and the teens elsewhere.
Temps may have a hard time rising above freezing in the NYC
metro area and coastal sections on Fri, and it should remain
quite cold inland, with highs only 25-30. Record low temps for
BDR/LGA/JFK, and record low maximum temps for all climate sites
except NYC, may be in jeopardy on Friday. See the Climate
section for current records.

As the high slides east Fri night, the precip shield with weak
low pressure passing well south off the Mid Atlantic coast may
skirt the area. Forecast carries 30-35 PoPs for Long Island,
20-30 PoPs most elsewhere, and it may remain completely dry in
Orange County with only 20 PoPs. Any snow amts would be on the
light side, with no more than a coating mainly for NYC
metro/Long Island.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Key Points:

* Light precip remains possible Saturday morning, especially
  east of the NYC metro and Hudson River.

* Mainly dry conditions should then prevail late Saturday
  through early next week.

* Below normal temperatures expected through early next week.

* A cold air mass appears likely Sunday night through Tuesday.
  Highs on Monday may struggle to rise above freezing even down
  to the coast.

The modeling is in good agreement with the overall pattern for
the upcoming weekend. A mainly flat, progressive flow will keep
weak low pressure well offshore over the Atlantic on Saturday.
Upper trough axis persists to the NW across the Great Lakes.
There may be a weak surface trough over the northeast on
Saturday, so have kept low precip probabilities for now. Any
precip that occurs would be occurring within marginal thermal
profiles. Light rain is possible at the coast with possibly some
wet snow inland. It should be noted the day could end up dry as
the lift and moisture is limited Saturday morning.

Conditions should improve heading into Saturday night as weak
high pressure builds returns through Sunday. A stronger cold
front will move across the area Sunday night that will usher in
a cold air mass for early next week. The cold air looks to hang
around into Tuesday. Lows Monday look to fall into the teens and
low 20s with highs on Monday in the upper 20s and low 30s. Lows
Tuesday morning may be in the teens for much of the area with
highs moderating a bit into the 30s. Moderating temperatures are
signaled with the latest model consensus indicating highs
rebounding into upper 30s inland and low to mid 40s near the
coast.

A clipper system may move across the northeast on Wednesday,
but this is a week out and models/ensembles differ on timing and
strength of the low pressure.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
High pressure in place gradually weakens overnight as a cold front
approaches from the northwest. The cold front moves through during
the afternoon Thursday. High pressure then builds to the west late
Thursday and over the region late Thursday night.

VFR. With the passage of the cold front Thursday a brief period of
snow showers will be possible which will be accompanied by strong
and gusty winds. Maintained the 2 hour PROB30 for the best timing of
the snow showers, however, this will likely be refined with later
forecasts.

Light NW to light and variable winds overnight become light westerly
toward 10Z. The winds then increase slightly into early Thursday
morning. With the passage of a cold front northwest winds will
quickly increase to 15 to 19 kt with gusts around 30 kt. Winds and
gusts begin to diminish around 00Z Friday with the gusts ending late
Thursday night.

      ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

No unscheduled amendments expected into Thursday morning.
Amendments will be possible for the cold front passage and the
possibility of snow showers.

.OUTLOOK FOR 06Z FRIDAY THROUGH MONDAY...

Late Thursday night: VFR.

Friday: VFR during the day. Chance of MVFR and light snow at night,
especially for southern and eastern terminals.

Saturday: Chance of MVFR and light rain in the morning, mainly E of
the NYC metros.

Sunday through Monday: VFR.

.MARINE...
Seas 5+ ft should continue on the ern ocean waters tonight,
lower elsewhere. These then spread to all ocean waters daytime
Thu ahead of a cold front, along with gusts up to 25 kt. After
fropa in the afternoon, expect solid gales on the ern ocean
waters from late Thu afternoon into Thu evening, and a Gale
Warning has been issued. Gales are also possible on all other
waters during this timeframe, except on the NY Harbor, and a
Gale Watch has been issued. Ocean seas should build to 5- 8 ft
by Thu evening, and up to 5 ft on the central/ern Sound.

Winds and seas quickly ramp down late Thu night, with sub-SCA
cond on all waters by daytime Fri and continuing through the
weekend. The next chance for SCA conditions occurs Sunday night
into Monday as a cold front moves across the waters.

&&

.HYDROLOGY...
No hydrologic impacts are expected through the middle of next
week.

&&

.TIDES/COASTAL FLOODING...
Water levels may touch minor flood thresholds at the Bridgeport and
Stamford tide gauges with the midday high tide on Sat as low pressure
passes well south.
