.DISCUSSION...
KEY MESSAGE 1...
Low pressure passing to our north in Canada has lead to broad
warm air advection showers developing across the area with a
warm front. These showers are expected to increase in coverage
west to east into the afternoon and evening. A mid-level
shortwave along with a strong southerly 40-50 kt LLJ will
provide most lift for these showers.

There is some elevated instability (around 500-800 J/kg of MUCAPE)
seen in the latest 12Z CAMs, primarily across Long Island and NYC.
Decent 0-6km bulk shear is also expected to develop in the same
areas, 30-45 kt. Some of these showers are expected to become
thunderstorms, primarily starting just east of NYC metro this
afternoon, with better odds across Long Island into early this
evening, before all precipitation exits east late this evening into
early tonight.

Rainfall totals are around 0.4-0.6" across the area, with lower
totals across areas far N & W of NYC. Localized totals near or just
above an inch are possible in any heavier thunderstorms that may
develop. Flood concerns are still minimal, at this time, and the
rain is expected to be largely beneficial.

Confidence is higher for fog development tonight into early tomorrow
morning after the rain ends, especially for Long Island and southern
CT, where the fog could become locally dense late tonight. Should
dense fog become widespread, a dense fog advisory may need to be
issued.

KEY MESSAGE 2...
Sunday morning and early afternoon looks to be mostly dry between
systems as a cold front approaches from the west. Scattered showers
are possible from mid to late afternoon from NYC north/west. A more
organized rainfall event is then expected Sunday night into Monday
as an amplifying upper trough sends the cold front across, with one
or more weak frontal waves passing well to the south and east.
Another 1/4 to 1/2 inch of beneficial rainfall is expected, with
lesser amounts of 1/10 to 1/4 inch NW of NYC.

Highs on Sunday have the potential to near 80 degrees in portions of
NE NJ and NYC metro. Otherwise, highs will be in the 70s across the
area. The chance for thunder appears low in the afternoon/evening,
but a few thunderstorms are possible given strong warming at the
surface if timed well with lift from the frontal boundary.

KEY MESSAGE 3...
Low pressure over the Northern Plains Tuesday is expected to
dive southeast over the southern to central Great Lakes region
Tuesday night, then eject off the Mid-Atlantic Coast late in the
day Thursday into Thursday night. This coastal low then slowly
heads northeast through the rest of the forecast period, with
some slow strengthening.

An inverted trough extending northward from the low as it passes
south of the area will likely be the primary focus for showers for
late Wednesday into Wednesday night. Of course, this far out, there
are timing differences with the track and strength of the low, which
would lead to differences in timing of any precipitation and
amounts. This also leads to high uncertainty with the track of the
eventual coastal low that passes south and east of the area at the
end of the week, and whether we see any rainfall as it heads out to
sea.

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
A disturbance moves across the terminals into this evening. A
frontal system approaches tonight and moves across the terminals
late Sunday.

Mainly VFR with areas of MVFR ceilings and showers this
afternoon. Some local IFR possible in any heavier showers.
There is a chance for thunderstorms in the NYC metro from around
19-22z, so have maintained a PROB30 for this potential. The
chance for thunderstorms is a bit higher across Long Island and
southern Connecticut terminals, generally 20-24z. Showers and
any lingering thunderstorms should push offshore after 00z.

Confidence in flight categories is low this evening, but
conditions should become MVFR to IFR through the evening, then
IFR-LIFR overnight. The highest chance for LIFR appears to be
from JFK/LGA/HPN on east across Long Island and Southern
Connecticut. Improvement to VFR expected Sunday morning after
12z.

S-SW winds increase into the afternoon, becoming 10-15 kt.
Gusts 20-25 kt possible 17-20z, especially for coastal
terminals. Winds will weaken this evening, becoming light and
variable overnight. A light W-SW flow develops Sunday morning.

 ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Gusts could linger through 20z.

Conditions may fluctuate between VFR and MVFR this afternoon
and early evening.

Timing of PROB30 TSRA may be off by 1-2 hours.

Confidence is low with ceilings and visibilities overnight into
early Sunday with amendments likely. There is chance of VFR
00-03z, especially at EWR and TEB.

.OUTLOOK FOR 18Z SUNDAY THROUGH THURSDAY...

Sunday Afternoon-Night: Mainly VFR. Chance of showers and MVFR
in the evening. Showers likely, especially closer to the coast
at night along with MVFR, potentially IFR at times.

Monday: Showers and MVFR early, especially near the coast, then
VFR.

Tuesday: Mainly VFR. NW winds G15-20 kt possible in the
afternoon.

Wednesday: Showers developing through the day. MVFR or lower
conditions. S winds G15-25 kt in the afternoon and evening.

Thursday: Showers possible with MVFR or lower conditions.

.MARINE...
S winds 15-20 kt with gusts up to 25 kt on the ocean and the Long
Island south shore bays this afternoon/evening, with ocean seas
building to 5 or 6 ft, as well. Some 5-ft seas could linger into
this evening on the ocean. We`ll drop below SCA-levels on all waters
tonight into Sunday morning. Sunday afternoon into Sunday night,
another period of 5 ft seas is possible on eastern ocean waters with
a cold frontal passage. Below SCA-criteria is then expected
to remain through Tue Night.

Waves build late in the day Wednesday as a southerly flow increases
due to an approaching low pressure system to the west. SCA
conditions are possible for the ocean waters for a brief period from
Wednesday afternoon into the first half of Wednesday night.
Thereafter, winds and waves are expected to remain below SCA
criteria.
