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
Sped up the rain but otherwise the forecast was on track. 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 through 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 00z Wednesday through Sunday
Low pressure system with a trailing cold front moves across the
region this evening and though the area overnight with light
showers continuing into early Wednesday. Conditions start to
improve after 09z as drier air moves in from the west.

Mainly ifr conditions are expected over tafs sites and will
likely remain in place until the early morning hours. Ceiling
heights could fall further between 500-1000 ft with low
visibilities for the first half of the forecast before MVFR
conditions move into to start the day.

East winds gradually become southerly winds prior to the
frontal passage. Then winds become northerly behind the cold
front between 06-12z Wednesday and northwesterly Wednesday
afternoon with gusts near 20kt possible.

Outlook for 18z Wednesday through Sunday
Wednesday-Thursday BecomingVFR. Chc W gusts 20-25kt on
weds.

Friday-Saturday Chc MVFR and rain Fri pm into Sat am.

Marine
Increased seas on the ocean slightly based on obs, otherwise
the forecast is on track. Small craft advisory remains in effect
for the ocean waters through Wednesday evening. Wind gusts on
the ocean will increase late tonight and could reach 25 kt into
Wednesday morning as a cold front pushes through the waters.

Ocean seas will then remain elevated through Wednesday, mainly
due to easterly swells. Seas will begin to subside Wednesday
afternoon with winds falling below 25 kts.

Winds and seas are expected to remain below small craft advisory
levels Thursday through Saturday. Low pressure may develop south of
the waters on Sunday, producing at least advisory level winds across
the entire area. If some of the modeling is correct, gales with seas
building up to 12 ft will be possible on the ocean. For now, wna was
capped at 8 ft on the ocean. Conditions gradually improve behind the
system on Monday.

Hydrology
Rainfall amounts of 0.50 to 0.75 inches are expected through
tonight. No hydrologic impacts are expected.

No hydrologic impacts are anticipated through Tuesday.

shore back bays will likely fall short of minor coastal flood

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.
