Synopsis
A cold front continues to move to the south of long island this
morning. High pressure builds to the north this afternoon through
the weekend, and across the canadian maritimes early next week.

Low pressure may pass south and east of the local area during
the middle of next week, followed by a slow moving cold front
late in the week.

Near term until 6 pm this evening
Showers will remain possible this morning as the cold front slowly
moves to the south of long island. Weak waves along the front and
large scale forcing from the area lying in the right entrance region
of a 100-120 kt upper jet have slowed the fronts progress. Lower dew
point air is noted advecting into the interior behind the front.

This process will continue through the morning helping to dry
out the low levels.

One forecast challenge this morning will surround how long the
scattered showers persist. It appears the showers will gradually
shift to the south and east this morning as the front moves offshore
and upper support gradually wanes. Showers cannot be ruled out
across long island through around noon.

The next forecast challenge today will revolve around the degree of
cloud cover. The proximity of the upper jet will likely be enough to
support abundant middle and high level cloud cover well into the
afternoon. This is supported by bufkit time heights of the nam,
hrrr, rap, and GFS indicating a high amount of moisture from around
15 kft to 30 kft. This moisture does not diminish until this evening
and the best chance for seeing significant clearing would be across
the NW interior late in the day. Have gone with mostly cloudy
conditions through the day for much of the area.

High temperatures will be in the 70s today, much cooler than recent
days.

There is a moderate risk of rip currents at atlantic ocean
beaches.

Short term 6 pm this evening through 6 pm Saturday
The core of the strongest winds aloft push offshore this evening.

The bulk of the middle and upper level cloud cover should follow
with clearing skies. High pressure also builds closer to the
northeast as the upper trough settles over new england. With mostly
clear skies, light winds, and a dry airmass, low temperatures should
fall well into the 50s inland and near 60 along the coast. The nyc
metro may only fall into the middle 60s.

Saturday will feature high pressure and temperatures a few degrees
below normal for this time of year. Highs will reach the middle and
upper 70s. There will likely be just a few to scattered fair weather
clouds as the atmosphere overall is dry through the afternoon.

There is a low risk of rip currents at atlantic ocean beaches.

Long term Saturday night through Thursday
High pressure builds north of the region Saturday night, then
continues to move east into the canadian maritimes through the day
on Monday. This will create an environment favorable for the
development of stratus and drizzle light rain as easterly flow sets
up over the region. Several models indicate the potential for light
qpf during the Sunday-Sunday night timeframe, with the best chances
from nyc on east.

As the high moves offshore on Monday, an area of low pressure
developing along the southeast coast will begin to lift to the
north, while at the same time a trough will begin digging across the
northern plains. Significant differences remain with the timing and
amplitude of the upper trough as well as with the strength, timing,
and track of the low as it lifts north. While the model consensus
continues to track the coastal low south and east of the local area,
it will have to be monitored for tropical development through the
weekend.

A cold front then approaches the area late in the period, although
the timing of this feature remains uncertain due to the
aforementioned differences aloft.

With the potential for plenty of cloud cover, temperatures on Sunday
and Monday will be several degrees below normal, with highs
generally remaining in the mid 70s. Temperatures then gradually
moderate through the mid week period.

Aviation 08z Friday through Tuesday
A cold front settles just south of the region as high pressure
builds to the north.

MainlyVFR (patchy MVFR ceilings), with lingering showers expected
at times through 11-12z.

Mid and high clouds are then expected during the daytime.

Light winds will become northerly 10 kt or less. North winds may
back to the W NW for a short time in the afternoon, but then shift
back to the N NE by evening around 9-12 kt.
