.SYNOPSIS...
High pressure over New England shifts east today with a warm front
approaching tonight. The front lifts through during Saturday
morning, followed by a cold front Saturday night. The front then
stalls to our south on Sunday and lifts back as a warm front through
Monday into Tuesday as low pressure passes well to the north.
The associated cold front then moves east Tuesday night, with
high pressure returning midweek.

&&

.NEAR TERM /THROUGH TONIGHT/...
A ridge axis aloft shifts into the region today with surface high
pressure over New England moving offshore this afternoon. There`s
still a chance of a shower or two during the first half of the
morning in association with a weak shortwave passing nearby the SW
portion of the forecast area. It otherwise looks like a dry but
mostly cloudy day. Eastern portions however stand a better chance of
breaks of sunshine with stronger higher pressure. Clouds and onshore
flow hold high temperatures below normal levels.

A warm front then approaches tonight. Lift in association with the
front along with some help of a weak shortwave likely produce some
showers mainly for the late night hours. PWATs are quite high even
though most of the moisture is confined below 850mb. Can`t
completely rule out an isolated thunderstorm late at night as
elevated instability pushes in, but forcing is pretty weak overall.
This would also mitigate any hydrologic impacts. There could be some
fog as well but probably not dense anywhere as turbulent mixing just
above the boundary layer should be sufficient to prevent it.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Still some showers possible during the morning as the warm front
lifts north, then a prefrontal trough approaches the western zones
late in the day. SBCAPEs may build up to 1500-2500 J/kg here by this
time and mechanical lift from the approaching trough with PVA would
help overcome low-mid level capping that appears to be in place for
much of the day based on forecast soundings. Strong to potentially
severe storms could be possible in the afternoon to early evening
given the instability and winds aloft. Primary severe threat with be
for wind gusts with a fairly unidirectional flow through the column.
SPC continues to keep areas west of CT and LI in a marginal risk for
severe weather. PWATs will be high, but the flow aloft would allow
for fairly progressive cells without training. Chances are that any
hydrologic impacts would be minor, and WPC now has just about the
entire area out of any risk for flash flooding. High temperatures
return to near or a few degrees above normal on Saturday in the warm
sector and partial afternoon sunshine.

A trailing cold front then pushes through during Saturday night with
shower and thunderstorm probabilities tapering off overnight.

High pressure builds in from the west Sunday into Sunday night with
slight ridging aloft. Mostly sunny and not as muggy as Saturday.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
Mid level ridge axis overhead pushes offshore Monday as a trough
over the Upper Great Lakes advances east. Associated low pressure
with the trough lifts the boundary to the south back up and thru the
region as a warm front into late Monday. So while the bulk of the
day appears dry with latest guidance, increasing cloud cover by late
day could lead to a period of showers and thunderstorms into Monday
night.

Tuesday appears unsettled with the region warm sectored ahead of the
attendant cold front approaching from the west. Shear and
instability profiles look to increase, and any convective activity
could be strong to severe, especially as one goes west. Behind the
fropa Tuesday night, drier and cooler mid next week as high pressure
returns to the region.

Temperatures Monday and Tuesday range from the mid 80s for most to
lower 90s in parts of the urban NYC metro. With dew pts progged into
the 60s and 70s, heat indices in some locales, primarily urban NE NJ
and NYC metro, could approach or exceed 95F one or both days. Little
in the way of temperature relief behind the front, though drier air
in subsequent NW flow helps to lower humidity values mid to late
week.

&&

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
High pressure builds in from the northeast today, as a frontal
boundary remains draped to the south over the Mid Atlantic.

Marginal MVFR cigs develop into early morning at most terminals,
with improvement expected by 15Z Fri. Cigs then lower once again
after 3Z Sat, with light rain developing from west to east. Cigs and
potentially vsbys go IFR into Sat AM.

Winds remain E to NE through the overnight and morning, with gusts
developing by mid morning, toward 20 kt. Winds gradually veer SE
into the afternoon, with gusts diminishing by 00Z Sat.

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

Amendments possible for timing of MVFR cigs this morning, and then
for the timing of improvement.

Gusts today may be more occasional at times.

Timing of IFR conds and rain into Sat AM could be off by a few hours.

.OUTLOOK FOR 12Z SATURDAY THROUGH TUESDAY...

Saturday: IFR in the morning. Showers likely with a chance of
thunderstorms and MVFR in the evening.

Sunday and Monday: Mainly VFR. A chance of showers and thunderstorms
late Monday and Monday night.

Tuesday: Showers and thunderstorms with MVFR or lower possible,
especially late afternoon and evening

.MARINE...
Non-ocean waters remain below advisory thresholds through Sunday
night. On the ocean, SCA remains in effect through tonight for both
winds and seas today, and mainly for seas tonight. Winds veer
southerly for Saturday at around 10 kt then increase Saturday night
ahead of a cold front. Gusts however likely remain below 25 kt.
Mainly offshore flow for Sunday below 10 kt.

Conditions are expected to largely remain below Small Craft Advisory
thresholds on coastal waters early to mid next week

&&

.HYDROLOGY...
Quick-moving heavy downpours are possible late Saturday into
Saturday night and could lead to some instances of nuisance flooding
in urban, low lying, and/or poor drainage locations.

No significant hydrological concerns thereafter.

&&

.TIDES/COASTAL FLOODING...
Isolated minor coastal flooding is possible in the most vulnerable
locales along the back bays of S Nassau and Queens during this
evening`s high tide cycle, as water levels come down slightly
from a new moon early in the week.

There is a high rip current risk for all south shore Long Island and
NYC beaches today. Surf heights of 3-4 feet with a long shore
current will lead to this high risk. Surf height lowers to 2-3 feet
on Saturday with onshore flow, so the rip current risk will lower to
moderate on Saturday.

&&

.OKX WATCHES/WARNINGS/ADVISORIES...
CT...None.
NY...High Risk for Rip Currents through this evening for NYZ075-080-081-
     178-179.
NJ...None.
MARINE...Small Craft Advisory until 6 AM EDT Saturday for ANZ350-353-
     355.
