Synopsis
High pressure builds in through Sunday, then a cold front approaches
Sunday night. The cold front moves through Monday morning,
followed by high pressure building in from the north and west
through mid week. The high then gradually shifts offshore by
late week ahead of a slowly approaching cold front.

Near term until 6 am Sunday morning
Deep-layered ridging with a downslope flow will maintain a
clear sky tonight. It will still be breezy this evening, but
winds will continue to subside through the night. Low
temperatures will be a few degrees below normal.

Short term 6 am Sunday morning through Sunday night
The high pressure ridge at the surface and aloft reach us on Sunday.

Sunny at the start, then some higher level clouds move in over the
ridge in the afternoon. A subsidence inversion will limit mixing to
around 900mb, where the forecast afternoon temp is around 4-5c. This
combined with sufficient sunshine and a wsw flow 10-15 mph should
allow highs to reach near 60 in parts of NE nj, with even some spots
in the city possibly reaching 60. The rest of the area should see
mid and upper 50s.

A cold front and shortwave then approach Sunday night. This will
bring low chances of showers after midnight. Thermal profiles
would support a mix of rain and snow for the higher elevations
of western orange county.

Long term Monday through Saturday
A potent upper trough allows an attendant cold front to pass through
Monday morning, though with a separate approaching short wave to the
west, overrunning showers may continue into the afternoon. Rainfall
amounts will generally be light, and although there is the potential
for snow to briefly mix in as the event ends during the afternoon,
do not expect any accumulation. Both deterministic and ensemble
forecasts have backed off significantly on the amount of any frozen
precipitation.

Thereafter, the broader upper trough phases with the short wave and
moves offshore, with increasingly confluent flow aloft allowing a
surface high to the west to strengthen as it moves east. A colder
air mass only briefly settles across the region. Expect close to
seasonal normals for highs on Monday, followed by below normal
temperatures Monday night, though a tightened pressure gradient will
allow some typically cooler locales on long island to remain mixed,
preventing even colder lows.

Below normal temperatures continue into Tuesday, though the air mass
will slowly begin to modify, allowing temperatures to be a few
degrees warmer. The surface high then shifts offshore Wednesday,
allowing a return to southerly flow and warm advection for the
remainder of the week, with near normal temperatures on Wednesday
becoming above normal into the late week. With the cool ocean
temperatures, expect coastal locales to generally remain in the 50s,
but temperatures in the 60s will be common across the interior.

Overnight lows will become increasingly mild as well. Although the
forecast is for mostly sunny skies, with continued onshore flow warm
advection over the cool ocean, will need to monitor for the
potential development of stratus into the late week that may yield
cooler daytime highs and warmer lows than forecast.

Aviation 20z Saturday through Thursday
Deep low pressure tracks through the canadian maritimes as high
pressure builds in from the west.

Vfr. Gusty wnw winds, just to the right of 310 magnetic, will
continue through the afternoon with wind gusts between 25-30kt. Can
not rule out a few peak gusts higher than forecast.

The gusts will diminish later this evening and eventually end
between 02z to 05z. A few occasional gusts may continue after 05z.

Winds become more westerly towards daybreak and then more
southwesterly between 15-18z with speeds between 8-15 kt.

Outlook for 18z Sunday through Thursday
Sunday Vfr.

Monday MVFR possible with light rain in the morning, with a
cold frontal passage.

Tuesday and Thursday Vfr.

Marine
Gale warning has been dropped on the non-ocean waters, but
remains in effect on the ocean thru 22z. There still could be an
occasional gusts to 35kt for the nearshore non-ocean waters into
early evening. Winds and seas otherwise diminish through the
night. SCA is now up for the non-ocean waters through midnight
tonight, although the easternmost part of LI sound and
gardiner's bay could still see a couple of 25 kt gusts shortly
thereafter. On the ocean, SCA will need to posted for tonight.

This will likely go through tonight west of fire island inlet.

Farther east, a westerly flow gets just strong enough for
minimal SCA conds during the afternoon and evening. Would
therefore carry the SCA here through midnight Sunday night.

The pressure gradient is expected to tighten on Monday behind a
departing cold front as high pressure begins to build over the
waters. Ocean seas may briefly build to near-sca levels by Monday
night into Tuesday morning. Tranquil conditions then follow as high
pressure begins to settle into the region through mid to late
week.

No hydrologic impacts are anticipated for the next 7 days.

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.
