Synopsis
A warm front approaches from the south this evening then lifts
north through the region late tonight and early Tuesday morning.

A cold front then crosses the tri-state Tuesday afternoon and
early evening, followed by a trough of low pressure pushing
through the remainder of Tuesday night. High pressure then
builds in for the rest of the work week, followed by a frontal
system over the weekend.

Near term until 6 am Tuesday morning
A deep layered ridge axis lifts to the NE tonight. With SW flow
aloft, e-se flow at the surface, and dry mid levels, expect
mainly areas of drizzle and fog into the overnight hours. As
low to mid level isentropic lift and saturation increases
overnight expect rain to develop from SW to NE after midnight.

For now do not expect anything other than locally dense fog,
mainly, if not entirely, during the overnight hours so will
address with special weather statements as appropriate.

Lows tonight should occur this evening, then temperatures should
slowly rise overnight in response to low level warm advection.

Lows should be from the mid 30s to around 40, except lower 40s
in the immediate nyc metro.

Short term 6 am Tuesday morning through Tuesday night
As a warm front continues to push north tonight and into
Tuesday a deep moisture airmass along with precipitable water
values of 1 to 1.25" will set the stage for periods of moderate
to locally heavy rainfall, as a cold front approaches late
tonight and moves across the area Tuesday morning. The front is
forecast to move through fast, so the heavy rainfall at this
time doesn't seem to be a significant threat.

There will be some good instability ahead of the approaching cold
front. Will continue the mention for an isolated thunderstorms as
the cold front makes its way across the area. There is also the
potential for strong winds above the surface to mix down in any
thunderstorms. Regardless, a tight pressure gradient will lead to
strong winds across the area through the day but at the moment it
appears winds will be brief and sporadic enough to preclude a wind
advisory for now.

The front will pull offshore by Tuesday evening. Northwest winds
behind the front will usher in more seasonable temperatures. Tuesday
nights low will be in the low to mid 30s.

Long term Wednesday through Monday
Not much change in the 12z data regarding the long term. High pres
builds in from the W on wed, with wnw winds ushering in a colder
airmass. Deep mixing provides a high confidence in temps, so a blend
of the data was used. There could be a period of bkn-ovc aftn cu
which the model data is not picking up on attm, so an upgrade in
cloud cover is possible with subsequent updates.

With deep unidirectional flow, winds should keep the lowest lvls
mixed Wed ngt. Temps therefore not as cold as a pure MOS blend.

Still breezy on Thu but deep subsidence will produce a sunny day.

The superblend was used for temps.

Still in the cool regime Fri as return flow does not commence til
late in the day. The superblend again used for temps. Some mid clouds
may infiltrate the skies if the WAA aloft develops fast enough.

A warming trend on Sat as a frontal sys approaches. The GFS and
ecmwf have diverged on timing however, with the ECMWF now about 24
hrs slower than the gfs, bringing the cdfnt and bulk of the rain in
on mon. The fcst remains close to the more consistent timing of the
gfs, with pops focused on Sun and Sun ngt. Lower pops remain in
place for mon, but again this could change if the ECMWF becomes a
trend. The superblend was used for temps.

Aviation 00z Tuesday through Saturday
A warm front just S of long island will push through late
tonight followed by a cold front Tue aftn.

Difficult forecast continues, especially for nyc and long
island terminals. Generally ifr lifr conds have moved in early
this eve with the exception of kjfk kewr who remainVFR. The
stratus is expected to move in here as well by 03z. There is
some indication in the guidance that conds sct out, mainly
nyc LI terminals between say 03z and 09z due to turbulent
mixing aloft. Have kept this idea in the forecast and will see
how it goes, although there is the possibility that it does not
occur. Otherwise, rain forecast to move in 09-13z. Any
improvement tomorrow is forecast to be gradual. Moderate to
heavy rain showers and isolated thunderstorms will impact the
area from daybreak through the afternoon with the approach of a
cold front.

E NE 5-10kt become light and vrb away from the coast overnight.

Winds veer to the SE then S late tonight into Tuesday morning
as warm front pushes north of the region. Llws compression
likely Tuesday with gusts up to 35 kt possible, strongest for
kisp kgon. Cold frontal passage with wind shift to west will
occur from mid to late afternoon.
