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
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 low 60s along the coast.

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
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.

the air.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
