.WHAT HAS CHANGED...
Added showers or sprinkles for western areas into early this
evening.

Cold frontal passage timing has sped up for Wednesday. High
temperatures knocked down some.

&&

.KEY MESSAGES...
1) Well above normal temperatures through Wednesday.

2) Backdoor cold front passes through late Wednesday afternoon
into evening.

3)A frontal boundary meanders across the region Thursday night
into Sunday with above normal temperatures and chances for
showers from time to time. More seasonal temperatures return
Monday.

.DISCUSSION...
.KEY MESSAGE 1...
Warm days and mild nights will prevail into Wednesday with
gusty SW winds each afternoon. A frontal system will set up to
the north tonight, where it will remain into Tuesday. A nearly
zonal flow aloft and deep-layered westerlies will allow for
continued warm advection across the area. Temperatures during
this time will average 10 to 20 degrees above normal. Lows
tonight will be in the 40s and 50s, and then the 50s and 60s
Wednesday night. Highs Tuesday are expected to get well into the
70s for NYC and points north and west. Urban portions of NE NJ
may even hit 80. However, closer to the coast, highs will only
get into the 50s and 60s. At this time of year, with water
temperatures around 40, south winds will keep the immediate
south shore of LI and the Twin Forks the coolest.

The best chance for any records to fall will be for high
minimum temperatures each morning. See Climate Section below
for potential record high and record high min temperatures
Tuesday and Wednesday.

In addition, there will be a chance of showers overnight into
Tuesday morning due to the warm advection. While the NBM is
carrying likely PoPs, this may be too high. Forcing in the
warm sector looks disorganized. Thus,coverage may be more
scattered in nature. Rainfall amounts from a tenth to a quarter
inch are expected.

There is a chance of showers and isolated thunderstorms
possible Tuesday evening/night in conjunction with disturbances
in the westerly flow.

For daytime SW winds Tuesday afternoon, blended in NBM 90 with
the NBM.


.KEY MESSAGE 2...
Guidance is trending faster with a backdoor cold front dropping
south across the area Wednesday afternoon and evening. Based on
this trend, went cooler than the 13Z NBM. Used model consensus
from 12Z. This keep highs sufficiently below records. This will
have to be watched as any speed up or slowdown of the front
will have a significant impacts on the high temperatures.

Rain chances will be on the increase as well both due to
instability along and ahead of the cold front and then post-
frontal with overrunning as low-level cold air drains into the
area behind the front.


.KEY MESSAGE 3...
A frontal boundary becomes nearly stationary south of the
region Thursday, following a cold frontal passage. This east to
west oriented frontal boundary will meander across the region
Thursday night into Sunday, moving north as a warm front, and
then south again as a cold front as one low pressure center
tracks to the west and north Thursday night into Friday, with
another low pressure center late Saturday into Sunday night.
There is uncertainty as to the timing of the frontal boundary,
and how far north and south the front will move. As a result
this will have an impact on temperatures, and while there are
chances for precipitation much of the time, there will be
periods of dry weather. Overall, above normal temperatures are
expected from Thursday night into Sunday, potentially being as
much as 15 to 20 degrees above normal at times.

The deeper low passing west and north Saturday into Sunday will
bring a strong cold front through the region late Sunday into Sunday
night, with temperatures returning back to more seasonal levels. A
few post frontal showers are possible into Monday, with drier air
Monday night as high pressure builds in from the west.

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
High pressure remains offshore with a frontal boundary set up to the
north into Tuesday. The boundary slowly approaches Tuesday night

SSW winds continue at around 10 kt for the city and coastal
terminals this evening as prevailing gusts end. Sustained winds
gradually weakening below 10 kt overnight. Winds increasing once
again from the SW Tuesday morning after 12z with gusts around 20-25
kt.

Mainly VFR. Can not rule out a few showers this evening, with a
higher chance especially after 05-06z terminals. No significant
impact to ceilings and visibilities are currently expected with the
best chance of MVFR at KSWF.

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

Adjustments possible for timing of showers tonight into early
Tuesday morning, otherwise no amendments are anticipated with any
showers having minimal impact on flight cats.


.OUTLOOK FOR 00Z WEDNESDAY THROUGH SATURDAY...

Tuesday Night: VFR conditions expected for the evening. SW-SSW winds
with gusts up to 25 kt in the evening. Chance of MVFR or lower.
Chance of LLWS at night, especially for eastern most terminals.

Wednesday: Chance of MVFR or lower and chance of LLWS early. MVFR or
lower with showers likely in the afternoon and evening. Isolated
thunderstorm possible. SW gusts 15-25 kt possible.

Thursday: Chance of showers. MVFR or lower possible. E wind gusts 20
kt possible.

Friday: Chance of showers and MVFR, otherwise pockets of VFR
possible. S wind gusts around 20 kt possible.

Saturday: Periods of VFR, with the chance of MVFR or lower in
rain/showers.

.MARINE...
For the non ocean waters the SCA was allowed to expire as
nearshore wind guts have diminished below 25 kt.

For the ocean waters, a prolonged SW flow will keep seas up at
5 to 10 feet into Wednesday, then subsiding late in the day as a
backdoor cold front switch winds around from the SW to E.
However, SCA conditions will likely continue into Thursday due
to strengthening E winds and seas of 4 to 6 ft.

Small craft conditions, gusts and seas, continue into Thursday
evening on the ocean waters, falling below by late Thursday night as
easterly winds diminish and shift to south by Friday morning.
