Synopsis
High pressure builds down from the canadian maritime provinces
through Thursday. A warm front passes to the northwest Thursday
night, followed by a cold front crossing the tri-state late Friday
night into Saturday morning. The front settles just to the south
into early next week as strong high pressure builds to the north. A
slow moving frontal system will move towards the region the middle
of next week.

Near term until 6 am Thursday morning
High pressure builds southward into the region tonight. A
northeast to east flow and subsidence inversion should allow low
stratus to move back into the region tonight, possibly
remaining into Thursday morning. The main question will be how
far west the stratus reaches.

Lows tonight will fall into the 50s and 60s. A mav met ecs
blend was used for overnight lows.

There is a moderate risk for the meteorological enhancement of
rip current formation at atlantic ocean beaches today.

Short term 6 am Thursday morning through Thursday night
Thursday morning will start off with cloudy or mostly cloudy
skies as stratus remains over the region. The cloud should start
to dissipate by mid morning as drier air moves into the region,
however we could still be looking at a partly cloudy day,
especially across the western half of the region as high clouds
start moving into the region as a cold front approaches from the
west.

As a cold front approaches Thursday night, clouds will once a
again increase. Despite the cloud cover will go with a dry
forecast through the short term, thinking that any precipitation
will hold off til Friday.

Temperatures on Thursday will climb into the lower and middle
70s, while lows Thursday night fall into the 50s and 60s.

Forecast guidance was in good agreement with temperatures and
used a blend of the mav met and ecs.

There is a moderate risk for the meteorological enhancement of
rip current formation at atlantic ocean beaches through
Thursday.

Long term Friday through Wednesday
Generally a zonal upper flow expected through early next week
between southeastern us ridging transitioning to bermuda ridging,
and a hudson bay upper low sliding into eastern canada. Good
agreement between models in a pac shortwave rotating through this
flow through the great lakes on Friday and then the northeast
us Friday night.

At the surface, decent agreement with a frontal system approaching
the region on Friday in response to this shortwave. Instability and
winds fields suggest an organized line of convection developing
across western ny pa and tracking eastward in the afternoon. Timing
of lagging shortwave forcing front indicate that this line would not
make it into the region till the overnight hours. With waning
instability and lagging forcing, it is questionable how far eastward
into the region any strong to damaging wind threat would maintain as
strong shear wind could lead to an outflow dominant transition. At
this point, areas n&w of nyc would have a marginal risk for some
strong to damaging winds gusts if this line arrives in the evening,
with a diminishing threat as it approaches the deepening stable
layer near the coast.

Thereafter, a fall type airmass likely for the weekend into early
next week as the cold front settles just to the south and canadian
high pressure builds into new england. With close proximity to
stalled boundary and under periphery of the ridge upper jet, could
be looking at mid and high clouds streaming across the region
through the weekend. Perhaps a few sprinkles or light showers
possible across southern portions of the tri-state if the boundary
stalls close enough, but otherwise dry. Then a gradually
increasing chance for stratus and shower development Monday or
Monday night with approach of the next frontal system.

Then a good signal for a return to a moist tropical environment for
mid to late week as troughing begins to amplify into the central us,
and bermuda ridging remains stubborn. A slow approaching frontal
system will bring potential for rounds of showers and thunderstorms,
particularly across the interior, during this time along with a warm
and unseasonably humid airmass.

Aviation 20z Wednesday through Monday
High pressure over new england through Thursday.

Mainly aVFR forecast through the TAF period with exception of
eastern terminals where MVFR is expected. Any ceiling heights will
generally be in the 2-4k ft range, with the lowest CIGS NE of nyc.

Isolated ceilings to 1k are possible kgon and kisp especially late
tonight or early Thursday morning. Any broken ceilings overnight may
see a brief improvement to sct at times.

Winds generally n-ne tonight 10 kt or less especially
overnight.
