Synopsis
A cold front pushes through the region tonight followed by high
pressure building in from the southwest. A cold front pushes
through the region tonight followed by high pressure building
in from the southwest.

Near term until 6 am Wednesday morning
An upper-level trough and associated occluded surface low pressure
system will move its way northeastward into ontario through tonight.

A cold front will push in from the west further increasing moisture
ahead of it bringing a period of widespread rainfall tonight. The
steadiest rain will occur between 00z and 06z, tapering off from
west to east after 06z and clearing eastern long island and
southeastern connecticut by early Wednesday morning. Rainfall
amounts will be on average between 0.50 and 0.75 inches, with the
higher amounts to the north and west of nyc.

Low temperatures will be a few degrees above normal, in the upper
40s across the interior and in the 50s elsewhere.

Short term 6 am Wednesday morning through Wednesday night
The cold front pushes through by early morning with dry air
filtering in quickly behind resulting in a mostly sunny day. It will
also be breezy as high pressure builds in from the southwest and low
pressure departs. With ample sunshine, temperatures will warm a few
degrees above normal, into the low to mid 60s.

Mainly clear sky expected for Wednesday night, with winds
diminishing and temperatures cooling off into the upper 30s across
the interior and the pine barrens of long island. Elsewhere
temperatures will be in the mid to upper 40s and around 50 across
the nyc metro.

Long term Thursday through Tuesday
Sunny with highs in the low to mid 60s on Thursday with high
pressure centered southeast of the forecast area. The nbm was used
for temperatures. A clipper type system is then possible for late
Friday into Saturday. The ECMWF remains consistent with this
feature. A blend of the model data was used for precipitation
probabilities, which were capped at chance. The GFS would produce
less rain. The nbm was used for high temperatures Friday and
Saturday, with the consmos used at night. A chance of rain returns
Sunday and Monday due to a southern stream upper low and gulf of
mexico moisture. The GFS is now spinning up a surface low south of
the area on Sunday, producing a wind driven rain. The forecast has
been trended in this direction with support from the 12z ecmwf. A
large upper trough then approaches for the beginning of next week.

Chances for rain have been included in the forecast with the
possibility of falling heights. The nbm with minor adjustments was
used for temperatures.

Aviation 20z Tuesday through Sunday
Low pressure system and a cold front approach this evening and
move across the region overnight.

MVFR ifr conditions have overspread the region and will remain
in place through much of the TAF period. We will generally see
ceiling heights between 500-1500 ft for much of the evening
with widespread ifr or lower ceilings developing.

Light drizzle and showers have begun to develop at all terminals
and will become more widespread during the afternoon into the
evening. A more steady rain is likely overnight into early
Wednesday.

Ne-n winds averaging around 5-10kt. Winds veer more ene late
afternoon and evening. Southerly winds prior to the frontal
passage will be possible in the late evening. Winds become
northerly behind the cold front between 06-12z Wednesday and
westerly by Wednesday afternoon with gusts near 20kt possible.

Conditions start to improve after 09z as the front crosses the
region and drier air moves into the area.

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.
