Synopsis
High pressure continues to move offshore tonight as a cold front
approaches from the midwest. The front passes through the area
Thursday night. High pressure returns to the region for Friday
and Saturday. A frontal system will pass through the region late
Saturday into Sunday. The front will stall to the south of the
region Monday with a wave of low pressure passing through Monday
night. High pressure returns for Tuesday and Wednesday.

Near term until 6 am Thursday morning
Main update this evening to update sky cover, as an opaque area
of cirrus is moving into the lower hudson valley and will
quickly spread eastward. High temperatures seem to have peaked
later in the day, allowing deeper mixing and lower dew points
than previously forecast. Otherwise, forecast remains on track
with seasonable temperatures and a chance of showers tonight.

Previous discussion follows.

Both the upper and surface ridges will translate east tonight
with a return southerly flow developing by this evening. This
will result in gradually increasing low-level moisture with
overnight lows near or just above seasonable levels.

Warm advection on the backside of the departing ridge will
allow for increasing mid and upper clouds overnight along with
a chance of showers. The best chance will be from nyc and points
west as drier will be slow to erode to the east. Rainfall
amounts will be light and generally less than a tenth of an
inch.

Short term 6 am Thursday morning through Thursday night
Early morning showers will become isolated by afternoon as the
warm advection wanes. Any rain in the morning should be on the
light side.

The potential for a round of more significant convection arises
during the late afternoon and early evening hours on Thursday.

An upper low north of the great lakes on Thursday will track
ese, sending height falls into the region. This coupled with
moistening low-levels will destabilize the airmass. Their are
mixed signals from the guidance during this period as to whether
all the ingredients will come together at just the right time
to erode a low-level cap and overcome dry air in a deep-layered
westerly flow aloft. Additionally, the best dynamics will
reside north of the area. Mid level lapse rates do steepen to
around 7-8 deg c km and 0-6 km bulk shear is around 50 kt. Href
members show varying solutions with most in the camp of the
convection being scattered in nature. There is also the question
as to whether the shear is sufficient to maintain a cold pool
to push through the maritime airmass. So yes, there could be a
few strong and or severe thunderstorms, but that should mainly
be to the north and west of nyc. The convection will likely
dissipate as it approaches the coast. The best timing looks to
be between 6 and 10 pm, from west to east.

Warm advection during the first half of the day will result in
mostly cloudy skies, but there should be some breaks in the
afternoon. This will also be a factor into how much we can
destabilize.

Gusty s-sw winds ahead of the front will get up to 25 mph,
mainly near the coast.

Highs will be nearly seasonable levels, in the upper 60s at the
coast, to the mid 70s north and west of nyc.

Cold front passes through between 10 pm to 1 am Thursday night
with gusts NW up to 25 mph developing toward daybreak.

Long term Friday through Wednesday
High pressure builds across the region on Friday and most of the day
on Saturday, so expected dry conditions with temperatures in the mid
to upper 70s on Friday and upper 60s and lower 70s on Saturday. A
cold front will then approach the region Saturday evening and
overnight, bringing a threat of showers and thunderstorms across the
area. The front should push south on Sunday keeping the area under a
slight and chance probabilities of showers Sunday and into memorial
day. Temperatures on Sunday will be in the upper 70s to mid 80s with
temperatures on memorial day in the mid to upper 70s.

Dry conditions return on Tuesday and Wednesday as high pressure
builds into the region. Temperatures on Tuesday will start out in
the low 70s then warm up into the mid to upper 70s on Wednesday.

Aviation 00z Thursday through Monday
High pressure just offshore moves farther out to sea into
tonight.

Vfr through the evening push. Sea breezes should continue to
form head inland into early evening. Winds speeds 10kt or less.
