Synopsis
Strengthening low pressure departs to the north today with high
pressure slowly building into the region on Friday remaining
through the weekend. Another frontal system affects the area
Monday night into midweek, followed by high pressure thereafter.

Near term until 6 pm this evening
Nearing the peak heating of the day with current wind gusts in
the 25 to 45 mph range, have less confidence of reaching high
wind warning criteria. An isolated gust to 50 to 60 mph is
possible, but do not expect widespread 60+ mph any longer. Therefore,
have converted to wind advisory across the entire tri-state
until 6 pm tonight. Otherwise, forecast is on track.

As low pressure continues to lift away to the northeast it will
continue to strengthen, tightening the pressure gradient across the
region. Top of the mixed layer on bufkit soundings shows wind gusts
during the afternoon between 40-55 kts. Don't expect winds to gust
this high for the entire day, but peak wind gusts will likely be
in this range.

Today will remain mostly cloudy courtesy of cyclonic flow and cold
advection. With steep low-level lapse rates cannot rule out a
scattered shower, however any additional precip will be light.

The steep low level lapse rates will help mix down higher winds
as well.

Temperatures will be below normal as cooler and drier air filters
in, ranging in the mid 50s to around 60.

Short term 6 pm this evening through 6 pm Friday
High pressure will slowly build in from the west as the coastal low
moves into the canadian maritimes. Winds will begin to diminish
tonight, but still remain breezy with gusts ranging between 25
and 30 mph, with the strongest winds along the coast.

Otherwise it will be partly to mostly cloudy with temperatures
dropping into the 40s overnight.

Sunshine returns on Friday as high pressure over the ohio valley
draws closer. It will still be breezy and cool with temperatures
similar to Thursday, in the mid 50s to around 60.

Long term Friday night through Wednesday
Mainly dry conditions remain with high pressure moving overhead
Friday night into Saturday and offshore Saturday night into
Sunday. Models have trended farther south and east with a low
pressure system for Sunday into Monday. The forecast area will
be on the northern fringe of this possible storm, with slight
chance pops for showers mainly south of long island on Sunday.

High pressure builds down along northeast coast Sunday night
into Monday with a drier forecast for the region with that low
now farther offshore.

Another low pressure system may impact the area Monday night
into midweek as it approaches from the south and west. This will
likely bring a period of moderate to briefly heavy rain but the
exact timing of this is uncertain. The amount of rain is
uncertain as well. Models have exhibited difference with the
position and timing of this system over the last few days. This
will be a secondary low with the parent low moving from the
great lakes into southeast canada. Flow will become more
easterly Monday through Tuesday, advecting in more moisture.

High temperatures outlook features below normal highs Saturday,
near to slightly above normal Sunday, several degrees above
normal for Monday and Tuesday with a return to near normal
values on Wednesday.

Aviation 18z Thursday through Tuesday

Marine
With current wind gusts ranging from 25 to 40 kt, have converted
the storm warnings to gale warnings until 6 pm.

Storm warning remains in effect for all waters through 6 pm tonight.

Gusts slowly diminish tonight but remain at SCA levels into Friday
as a strong pressure gradient remains present. Winds and seas
diminish Friday night. Still probably some SCA wind gusts on the
ocean for Friday night and some 5 ft seas for eastern ocean as
well early, but otherwise below SCA conditions expected.

Winds and seas remain below SCA Saturday through Sunday night
with high pressure in place. Potential for SCA for the ocean
increases thereafter. A complex frontal system approaches
Monday, with an increased east to southeasterly flow developing.

This will allow waves to build on the ocean to 5 to 8 ft over
the ocean waters Monday into Monday night.

Hydrology
No hydrologic impacts are expected.

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

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
