Synopsis
High pressure builds across the area tonight into Saturday,
then offshore Saturday night. Tropical storm nestor is then
forecast to track well south of the region Sunday into Sunday
night. Weak high pressure follows for Monday before a frontal
system moves across the area Tuesday into Tuesday night. High
pressure will then close out the week.

Near term through tonight
A progressive upper air pattern will feature a departing trough
along the east coast and a building ridge from the west.

Surface high pressure approaches tonight with diminishing
northerly winds. This combined with clear skies and dry air
will allow for good radiational cooling. A frost advisory
remains up for most of the lower hudson valley, interior
southern ct, and portions of interior NE nj. The western half of
orange county ny will be close to freezing, but there is less
confidence for a freeze warning versus a frost advisory at this
time. Frost will be more patchy across the pine barrens region
of eastern long island.

Lows will be in the 30s to around 40 outside of the nyc metro,
which will get down into the lower and mid 40s. These readings
are a few degrees below normal.

Short term Saturday through Sunday night
Both the upper ridge and surface high build across the area on
Saturday with light winds, clear skies, and highs around 60.

The latter of which is just a shade below normal.

Saturday night will feature another night of light winds. There
will an increase in high clouds late ahead of an upper trough
lifting NE across the mississippi valley. The latter of which
will steer tropical storm nestor off the carolina coast on
Sunday. Before then though, there could be another night of
frost across the interior and pine barrens region of eastern
long island.

For Sunday, nestor tracks well south and east of the region with
the forecast area on the northern fringe of the rain shield.

Rain chances are only 20 to 30 percent at this time, highest
across long island and the nyc metro. The cloud shield is
expected to encompass the entire area with temperatures a shade
cooler than on Saturday. Any rain should exit to the south and
east early Sunday evening.

Models are generally in good agreement with the track of the
low to the south. The 12z NAM though remains a northern outlier
at this time. For the latest official track and intensity
forecast, refer to the latest advisories from nhc.

Long term Monday through Thursday
Weak high pressure at the surface will build in from southeastern
canada during this time frame, keeping the forecast area dry
Monday. With ridging aloft and increasing heights, temperatures
will be slightly warmer on Monday than Sunday, just a couple of
degrees above normal, in the lower to middle 60s.

A weakening low pressure over the great lakes will send a warm
front north of the region Tuesday into early Tuesday night. The
associated cold front will quickly follow move Tuesday night
into Wednesday morning. A weak area of low pressure may develop
along the front, which could help to enhance the precipitation
as the system becomes negatively tilted. However there are
timing differences in when this system becomes negatively
tilted, and thus uncertainty in where and when any heavier
precipitation falls.

High pressure builds in and dominates the weather pattern with dry
weather to close the week. Temperatures will be a slightly above
normal for Thursday and Friday as well.

Aviation 21z Friday through Wednesday
High pressure will build in from the west.

Vfr conditions through the TAF period. NW winds 15-20 kt with
gusts 25-30 kt will diminish this evening. Winds may occasionally
brief gust higher than forecast through 22z.

Saturday... Winds become SW mainly less than 10kt after 18z.

Ny metro enhanced aviation weather support...

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.
