.SYNOPSIS...
A warm front will approach tonight and lift through Thursday
morning. A slow moving cold front will then drop into the area
Thursday night into Friday. Unsettled conditions are likely this
weekend with the frontal boundary remaining nearby. The front
will move away on Monday, with high pressure slowly returning
into Tuesday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Forecast generally on track for the rest of the night.
Widespread showers remain to our north, but anticipate
showers to develop overnight as a warm front draws closer. The
overrunning moisture may also lead to areas of drizzle and fog
development towards day break. Low temps likely achieved early
in the upper 30s and low 40s. Temperatures should rise to 45-50
degrees by daybreak.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
Area of fog and some drizzle likely to develop in the morning
especially from NYC east as the warm front lifts through. CAM`s
meanwhile show potential for additional showers and isolated
tstms to move across from the west in the morning.

Any fog should become patchy in nature by afternoon, with temps
warming up to the lower/mid 60s across Long Island, and upper
60s/lower 70s from NYC west. S winds will become gusty after
warm fropa, with gusts up to 25-30 mph in the NYC metro area
and along the coast, and mostly 15-20 mph inland. Another
chance for showers possible ahead of the slow moving cold front
across parts of NE NJ. Air mass does not look all that unstable,
with SBCAPE no more than 200-500 J/kg in this area, so have
only mentioned slight chance thunder. This instability then
skirts NYC and Long Island in the evening, so once again have
only mentioned slight chance thunder for those areas. Do not
expect any svr potential with this activity.

Cold front should enter the area from late evening into the
overnight. As it does so, an upper jet streak well to the
north and mid level vort energy riding top a broad upper ridge
axis over the Southeast should bring another chance of showers
after midnight. Low temps will be mostly in the lower 50s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Key Points:

* Unsettled conditions are expected this weekend with a frontal
  boundary in the vicinity.

* Showers are most likely on Saturday and then again late Sunday
  into Sunday night.

* Improving conditions are likely Monday with high pressure slowly
  building towards the area on Tuesday.

* Seasonably cool temperatures Saturday should trend warmer on
  Sunday with some 70s possible for NE NJ, NYC metro and Lower
  Hudson Valley. Temperatures then trend cooler early next week.

Any showers remaining in the area Friday morning will come to an end
by afternoon as a cold front pushes south and high pressure builds
into the Great Lakes and Northeast. This should keep much of Friday
dry, but the high pressure quickly moves through, departing the area
by Friday night and into Saturday morning. A shortwave develops an
area of low pressure over the Ohio Valley and pushes into the
Northeast Saturday. This will bring a warm front pushing north
through the area and with it, the potential for showers Saturday
morning and through the day. The strongest WAA will be north of the
area with a possibility of the coastline seeing more showery
activity as opposed to a steady rain.

The warm front continues to push north of the area which may result
in a lull in rain for Saturday night, though a saturated BL may
result in continued drizzle and fog for much of the region Saturday
night into Sunday morning. The area is expected to be in the warm
sector of the initial low to the north with a secondary low pressure
system developing upstream along the cold front. This intensifying
low pressure system will advect additional moisture and provide
ample forcing for the area by Sunday night as the front approaches
from the west. Widespread rain, locally moderate to heavy, is
possible with the frontal passage. While there doesn`t appear to be
significant amounts of instability, there does seem to be enough
elevated CAPE to support at least a slight chance of thunder for the
time being, though this is highly dependent on the amount of cloud
cover and heating during the day on Sunday if the warm front is able
to push further north than anticipated.

The cold front pushes through Sunday night and into Monday morning.
Rain should come to an end by Monday morning, though some additional
showers may be possible Monday and Tuesday as the upper level trough
swings overhead providing for some additional lift. High pressure
then builds back in for the middle of next week.

Temperatures on Friday will be above average with highs in the low
to middle 60s. The cold front moves through and cools down the area
for Saturday back into the low 50s. The warm front moves north for
Sunday allowing temperatures to rise into the 60s to possibly low
70s for portions of NJ and NYC, though this particular day`s highs
will depend on the proximity of the warm front and any cloud cover.
Otherwise, a generally cooling trend is expected through the middle
of next week with highs Monday into the upper 50s and cooling down
to the upper 40s to low 50s by Wednesday.

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
A warm front passes through this morning. A cold front reaches
the area tngt.

Conditions are expected to continue to deteriorate overnight to
IFR/LIFR in low clouds, fog, and light rain or drizzle. There
will also be a chance of showers into today. Improvement today
in the warm sector will be mainly confined to the NYC and Lower
Hudson Valley terminals this afternoon. The eastern terminals
will likely remain IFR/LIFR through the day, and lasting into
tngt.

Chances for additional showers and possibly a tstm tngt, but
probs and coverage too low to include in the TAFs attm.

SE winds becoming S/SW with the passage of the warm front
this morning. Gusts overnight will be more persistent along the
coast and may for a time drop off or be less frequent. Gusts
likely return in the warm sector this afternoon. Winds lighten
tngt invof the front.

LLWS expected today with S-SW winds 45-55 kt at 2kft.

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

Wind gusts late afternoon/early evening may be occasional.

Amendments for flight category changes likely thru this
morning.

Low confidence visibility forecast this morning. KJFK could
remain IFR/LIFR through this afternoon.

.OUTLOOK FOR 06Z FRIDAY THROUGH MONDAY...

Late Tonight: Sct shwrs and possibly a tstm with a cold frontal
passage. Wind direction vrb with the front in the area.

Friday: Chance of MVFR in showers, especially in the morning
along the coast.

Saturday: MVFR to IFR with showers likely. E wind gusts 15-20kt.

Sunday: IFR in the morning, becoming MVFR. A chance of showers.
SW gusts 15-20 kt possible.

Monday: MVFR with a chance of showers, mainly in the morning.

.MARINE...
SE flow tonight increases to 15-20 kt with some gusts up to 25
kt, bringing marginal SCA cond to all ocean waters, with seas
building to 5-6 ft.

As a warm front lifts through late tonight into Thu morning,
expect sustained S winds 20-25 kt with gusts 25-30 kt to
develop, mainly on the ocean waters and the Long Island South
Shore Bays, where SCA has been issued for daytime Thu. Ocean
seas during this time should build to 5-8 ft. The other waters
may see occasional gusts up to 25 kt, and it is possible that an
SCA may be needed, especially for the central/ern Sound and the
eastern bays.

There is a chance for dense fog on the waters Thu especially in
the morning with the warm frontal passage.

SCA cond likely to continue on the ocean Thu night, with SW flow
still gusting to 25-30 kt especially out east, and seas 5-8 ft.

Sub-SCA conditions are likely Friday afternoon through Sunday
morning. By Sunday afternoon, an approaching frontal system
will allow ocean seas to build above 5 ft, with SCA likely.
Sheltered waters should remain below SCA. SCA conditions on the
ocean likely continue through at least Monday.
