Synopsis
A cold front will move slowly east across the area late tonight,
then stall just east of long island on Saturday. High pressure
will follow Saturday night through Tuesday. A cold front will
pass across the area Wednesday night followed by high pressure.

Near term until 6 am Saturday morning
Main update this evening to cancel the flash flood and severe
thunderstorm watches, as convection is rapidly diminishing in
intensity. A few spotty convective showers and stratiform
precipitation remain, but should pose little threat for the
remainder of the evening.

Leftover showers and tstms will end with the passage of the cold
front between 06z and 12z overnight. With light winds forecast
during this time, areas of fog will develop, possibly dense
across long island and southern ct where significant rainfall
fell earlier in the day.

Short term 6 am Saturday morning through Saturday night
With a digging upstream trough approaching Saturday, the cold
front may not make it too far off the long island coast. In
fact, it's possible that it might retrograde a bit until the
passage of this trough Saturday night.

Dryer air will advect east across the area Saturday night as
high pressure advects east toward the area.

Long term Sunday through Friday
A broad area of high pres will build in Sun and mon. This will
produce seasonable temps and mostly clear skies. A thermal ridge
will build into the region Tue into wed, producing a mini heat
wave. Some spots, particularly across nern nj, may hit the 2 day
heat advy criteria. As subtropical moisture becomes entrained
in the flow, an increase in high clouds can be expected by wed.

The cold frontal timing has slowed slightly from the previous
12z model suite, so right now the timing is for the late aftn
and eve. Although the best chance for tstms will be with the
fropa wed, there will be chances prior, albeit lower, due to the
unstable airmass and onset of lowering heights. Because of the
progged position of the front and tendency of the guidance to
smooth out the temp gradient, highs were manually raised on wed.

A significant cool down then looks to follow for the end of the
week. The models have been very consistent with this signal,
although the exact magnitude of the cold airmass remains in
question. It would not be totally surprising to see some lows in
the furthest outlying areas touch the upr 40s next weekend.

Aviation 03z Saturday through Wednesday
A cold front will pass through the area late tonight, then stall
nearby on Saturday.

Cold front in eastern pa is expected to push through the metro
terminals between 08z and 12z. There could be an isold shower
accompanying its passage but coverage too limited to include in
forecast. Generally expect MVFR to locally ifr to return to the
terminals by 05z and remain until the winds shift to the W nw
late tonight. Timing in tafs could be + - 1-2 hours.VFR then
returns W to E early Sat morning. Seabreezes expected at coastal
terminal during the aftn.

Outlook for 00z Sunday through Wednesday
Saturday night-Monday Vfr.

Tuesday Isolated showers and thunderstorms possible with
MVFR or lower conditions,otherwiseVFR.

Wednesday Scattered showers and thunderstorms with MVFR
possible. Gusty southwest wind to 20 kt.

Marine
A small craft advisory SCA remains in effect across the atlantic
ocean coastal waters through tonight as a cold front approaches.

Heavy showers and tstms are likely. Areas of dense fog are
possible until sunrise.

Weather conditions improve with the passage of a cold front
Saturday morning as winds and seas fall below SCA levels.

Winds and seas will increase ahead of a cold frontal passage late
Tuesday and Wednesday. Seas on the ocean may linger AOA 5 ft Wed ngt
behind the front. Winds and seas thereafter are progged to remain
blw SCA lvls.

Hydrology
A few spotty showers are possible tonight ahead of a cold front
but are not expected to pose a risk of flash flooding.

Impacts from potential showers and thunderstorms Tuesday into
Wednesday are uncertain at this point.

Okx watches warnings advisories
Ct... None.

Ny... None.

Nj... None.
