Synopsis
Weak high pressure moves east of the waters tonight. A low
pressure system tracks southeast of long island late tonight
into Wednesday morning. Weak high pressure builds in later
Wednesday, followed by a slow moving low pressure system
affecting the area Thursday into Friday. Weak high pressure
returns for Saturday. Another frontal system affects the area
for the latter half of the holiday weekend.

Near term until 6 am Wednesday morning
Forecast has been updated mainly for timing of the onset of
rainfall chances. Delayed chances by a couple of hours. Minor
hourly adjustments to temperatures and dewpoints were also made.

Anomalously large and deep upper trough and associated upper
low digs into the the central us tonight... With jet streak and
shortwave riding up the coast late tonight into Wednesday
morning. In response... Southern low pressure tracks to the mid-
atlantic coast tonight and then quickly near of just SE of the
40 70 lat lon Wed morning.

Still quite a bit of spread in terms of areal coverage of
rainfall between models. A rather tight gradient of heavier
rainfall from frontogenetic zone to the N NW of the low... Which
should mainly stay SE of li. With region in briefly favorable
left front quad of approaching upper jet streak... Have leaned
towards higher likelihood of light rain for city coast late
tonight early Wed morning... With decreasing chances for
measurable rain to the north and west. Gusty N NE winds develop
along the coast late tonight and continue into Wed morning in
response tot he low as well.

Short term 6 am Wednesday morning through Wednesday night
Anomalously large and deep central us upper trough and associated
upper low gradually slides east into the ohio tennessee river
valleys Wed into Wed night.

Initial shortwave jet streak and resultant coastal low pressure
departs Wed aft... With brief high pressure building in Wed aft eve.

Any rain pushes east early Wed morning... With gusty N NE winds wed
morning gradually subsiding into the afternoon. At least partial
afternoon clearing should allow temps to rise to near seasonable
levels... Upper 60s lower 70s.

Models in good agreement with increasing potential for rain
development late Wed night into Thu morning ahead of approaching
deep closed low with deep layered lift of sub- tropical
moisture tap. Easterly winds will be increasing as well... With
tightening gradient between warm front low pressure to the S sw
and canadian maritimes high. See tides coastal flooding for
associated impacts.

Long term Thursday through Tuesday
Unsettled pattern for much of the long term.

High amplitude upper level trough over the eastern two-thirds of the
country, with its axis stretching from the central great lakes
region to the gulf coast Thursday morning will push east and become
negatively tilted through the day. This is indicative of a mature
system.

At the surface, a warm front will approach from the south. However,
this front looks to remain south of the region, but should provide a
lifting mechanism. A moist airmass, with dewpoints rising into the
upper 50s, with some 60 degree dewpoints not out of the question,
will already be in place. As the upper low with the system moves
closer to the area, cooler air aloft will provide some elevated
instability. MUCAPE values of up to 500 j kg noted in some of the
models. A period of moderate to briefly heavy rain is possible
Thursday morning. Right now, just some general thunderstorms are
possible.

Although precipitation fields are not currently indicating a high
rainfall event for Thursday with flash flooding, there is a low
probability, given local climatology. The potential for embedded
convection, pwats near 1.50", and low pressure moving into the area
from the west all point to this potential. Although, winds will be
east, a shift more to the southeast on Thursday would be another
ingredient favoring excess rainfall. Again, would be more confident
in flash flooding if QPF was higher and occurring later in the warm
season, but for now, minor urban and poor drainage flooding seems
most likely.

Surface low pressure moves over the area Thursday night, then heads
northeast, into the gulf of maine Friday morning. Light showers will
continue for Friday on the back side of the low.

Weak high pressure builds in for Saturday, with another frontal
system impacting the area Sunday into memorial day.

Aviation 00z Wednesday through Sunday
Weak high pressure over the terminals will weak this evening as
a wave of low pressure moves off the mid atlantic coast. The low
will move south of long island through Wednesday morning, then
weak high pressure will build in once again behind the low
Wednesday afternoon. This high weakens late Wednesday as
another, deeper, low approaches from the west.

Vfr conditions are expected through the forecast period. There
is a low chance of MVFR ceilings and visibilities developing
briefly toward 12z along the coast, then improving as the rain
ends from west to east.

Light and variable wind this evening, becomes NE less than 10 kt
after 06z, then increasing to around 10 kt with gusts up to 20
kt possible. Winds will become E late in the day as the next low
approaches.
