Synopsis
High pressure builds to the north through Sunday then drifts
east early next week. A cold front approaches Wednesday and
passes through the region Thursday. Another cold front passes
through late Friday into Saturday. High pressure returns late
Saturday.

Near term until 6 am Sunday morning
Updated sky cover for the diurnal cumulus, which at the approach
of sunset was beginning to dissipate. The other uncertainty is
the increasing clouds in the easterly flow across the ocean
waters with bufkit showing increase across the waters east of
fire island inlet. Also not sure how far inland clouds will
develop. This will have a impact on the lows for eastern long
island as winds are expected to decouple.

Dry and pleasant conditions expected tonight as a large dome of
high pressure continues to build across the northeast.

Low temperatures tonight will be in the low to mid 50s inland
and upper 50s to lower 60s along the coast, except across the
long island pine barrens, where temperatures may fall into the
mid and upper 50s.

Short term 6 am Sunday morning through Sunday night
As high pressure drift to the east on Sunday, clouds will begin
to increase across the area. Light rain and drizzle is possible
Sunday and through Sunday afternoon primarily across coastal
areas. Otherwise, Sunday should remain generally dry.

High temperatures on Sunday will be in the low to mid 70s with
overnight lows in the 50s to around 60.

There is a moderate risk of rip current development at atlantic
ocean beaches Sunday morning. An increasing easterly swell
during Sunday will result in a high risk of rip current
development Sunday afternoon into Sunday evening.

Long term Monday through Saturday
Ridging along the east coast of the united states will
gradually weaken and drift into the western atlantic Monday
through 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 Thursday
and Friday. The strongest front will be late Wednesday night
into Thursday. The upper trough weakens Thursday with the flow
becoming more zonal during Friday when another, and weaker, cold
front crosses the region.

Have now kept the region dry Monday and Tuesday as the lowest
levels are no longer saturated. However clouds are likely in
the moist easterly flow under the subsidence inversion.

With the front Wednesday into Thursday both CAPE and
instability will be limited, so will have showers with only
isolated thunder possible. There are some timing differences in
the timing of the frontal passage, but sided with the faster
guidance. Another weak cold front passes through Friday into
early Saturday with just a slight chance of showers as there
will be little moisture or forcing with the front. With the
upper trough weakening have slowed the timing of this second
front.

Aviation 19z Saturday through Thursday
High pressure builds over northern new england this weekend.

MainlyVFR is expected through the TAF period. There could be
some sprinkles or periods of light rain on sun, with a low
probability that ceilings could drop to MVFR.

Winds generally become NE around 10 kt this afternoon. Light sea
breeze flow however at some of the coastal terminals. All areas lock
into NE flow tonight, and remain through sun.

Outlook for 18z Sunday through Thursday
Rest of Sun Low probability of MVFR. Sprinkles or periods of
light rain possible. NE winds 10-20 kt along the coast.

Mon Vfr. NE gusts 20 kt along the coast.

Tue Vfr.

Wed MVFR possible. Showers and thunderstorms possible.

Thu Vfr.

Marine
Made adjustments to the wind gusts which were minimal across the
forecast waters. Otherwise, no changes were mad at this time.

Small craft advisory conditions expected Sunday morning and
through Sunday night as wind gusts increase to 25 to 30 kt on
the ocean waters and seas build to 4 to 6 ft.

With a prolonged period of a strong and gusty easterly flow
continuing into Monday, SCA conditions are likely on the ocean
waters Monday and Monday night. The flow weakens Monday night
into midweek as high pressure over the waters drifts east and a
cold front approaches. With the approach of the front winds
also gradually shift to the southeast and south. Sub sca
conditions are expected by Tuesday and continuing into Thursday.

Hydrology
No hydrologic impacts are anticipated through the middle of next
week.

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

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