Synopsis
High pressure across northern new england and extending along
the coast, east of the appalachians, remains across the region
through Monday night before it begins to drift east Tuesday, as
a cold front approaches from the west. The cold front passes
through the region Wednesday night into early Thursday. High
pressure returns briefly Friday before another cold front passes
through late Friday into Saturday. High pressure builds over
the northeast Saturday and Sunday.

Near term until 6 am Monday morning
A strengthening inversion was allowing for clouds to expand
across our coastal areas on an onshore flow. With the inversion
in place through tonight expect clouds to continue to increase
through tonight. Dry conditions expected tonight with light
rain drizzle remaining just south of the area. With the
increased clouds and mixing tonight, temperatures along the
coast may not fall as low as current forecast lows.

Low temperatures tonight will be in the lower 50s inland and in
the mid 50s to around 60 along the coast.

Short term 6 am Monday morning through Monday night
Low level moisture will linger into Monday morning as an
easterly flow continues with high pressure remaining north of
the region. This will result in mostly cloudy conditions along
the coast Monday morning with conditions improving by Monday
afternoon.

Temperatures on Monday will be in the mid 70s.

There is a high risk of rip current development at the atlantic
ocean beaches through Monday evening.

Long term Tuesday through Sunday
The extended period Tuesday through Saturday is fairly consistent
with the previous forecast. Ridging from northern new england and
along the mid atlantic seaboard will drift into the western atlantic
early Tuesday as a longwave trough from near alaska digs into the
northern plains and upper midwest. This longwave trough will send a
couple of cold fronts through the region late Wednesday night into
early Thursday and then Friday into Saturday. The strongest front
will be the first one.

The changes with this front, is a quicker passage, and less forcing
along the front as the upper trough is now lifting farther to the
north and retrograding slowly. So, will still have chance
probabilities. With the longwave upper trough weakening Thursday and
Friday and the flow more zonal the next front will be even weaker
than earlier expected, with little moisture. As a result, this front
is now forecast to come through dry.

With the front Wednesday into early Thursday both CAPE and
instability will be limited, so will have showers with only slight
chances of thunder, and mainly across the inland, until later across
the marine areas, right with the frontal passage.

Higher pressure then builds in for the upcoming labor day weekend.

Aviation 00z Monday through Friday
High pressure will remain over new england through Monday night
before departing to the east on Tuesday.

Forecast challenge is to how far west MVFR ceilings over SE new
england work overnight. For the time, have confined it to some
of the coastal terminals for a period after 06z. The best chance
would be at kgon. Winds do become more northerly overnight
which may keep the lower ceilings to the east of the terminals.

This pattern will keep the area under a ne-e flow during the
time period with backing to the NE tonight and then veering more
to the E as the day progresses on Monday. Outside of a few
gusts into the teens this evening winds will be 10-15 kt at the
coastal terminals and 5-10 kt at the inland terminals.

Outlook for 00z Tuesday through Friday
Mon night-tue Vfr.

Wed MVFR or lower possible in showers and thunderstorms.

Thu MainlyVFR. Morning showers possible.

Fri Vfr.

Marine
Strong and gusty northeast to east winds remain across the
ocean waters, and were a couple of knots higher than forecast.

As a result, ocean seas have increased up to 8 feet across the
outer portions of the forecast zones. Winds and gusts will only
subside a couple of knots overnight, so increased winds, gusts,
and seas through the overnight. Also, updated the SCA that
remains in effect on the ocean waters through Monday night.

Winds should gradually diminish on Monday, but seas will remain
above small craft advisory conditions through Monday night.

Hydrology
No hydrologic impacts are anticipated through the end of the
week.

Tides coastal flooding
A prolonged period of easterly flow will gradually increase tide
levels into mid week. Localized minor coastal flooding is possible
with Monday evening high tides along the south shore back bays of
queens and nassau counties, with the threat of at least isolated
minor coastal flooding continuing during the evening high tide
cycles through the mid week period.

Equipment
Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.
