Synopsis for the long island waters and new york harbor.. Weak low pressure will pass just southeast of long island this morning and eventually into the gulf of maine this afternoon into tonight. A cold front will move across the waters tonight with high pressure building in thereafter through Tuesday. This will give way to an approaching low pressure system for midweek. The central low of this system moves northeast of the region by Thursday and into the canadian maritimes by Friday. Meanwhile, high pressure will gradually build into the waters from the south and west for the end of this week.

Synopsis
Weak low pressure will pass just southeast of long island this
morning and eventually into the gulf of maine this afternoon into
tonight. A cold front will move across the area tonight with
high pressure building in thereafter through Tuesday. Deepening
low pressure will move across the area Wednesday, tracking
across the canadian maritimes late in the week. High pressure
builds next weekend.

Near term until 6 pm this evening
Upper level jet streak exits to the northeast today along with
the weak surface low. The low will be moving from just southeast
of long island to eventually the gulf of maine by tonight.

Rainfall is expected to end early this morning with a gradual
decrease in clouds from west to east as flow aloft becomes
quasi-zonal.

There will be another cold front approaching late in the day but
this will be weak as the parent low will be filling during the
day with an increase in its central pressure. The overall
westerly flow through the atmosphere will make moisture quite
limited with the front.

Therefore, continue to have a decrease in clouds today into this
evening. Went with warmer side of guidance and slightly
increased across northeast nj, nyc and lower hudson valley with
high temperatures. The highs used originated from a blend of ecs
and gmos. Highs forecast range from the upper 60s to mid 70s.

Short term 6 pm this evening through 6 pm Tuesday
Quasi-zonal flow remains tonight into Tuesday but becomes more
sw late Tuesday, which will be in advance of an approaching
upper level trough.

The aforementioned cold front will be moving across tonight but
with the lack of moisture, still expecting a lack of clouds
tonight. Surface winds are expected to shift from SW to NW and
will be quite light across the interior, which will help the
interior radiatively cool more. Used ecs for low temperatures
tonight to depict a more vast range of lows and going with
relatively cooler guidance for interior locations. Lows forecast
range from the upper 30s to lower 50s.

For Tuesday, the NW flow will allow the coastal locations to be
just as warm and in some cases a little warmer as the interior
locations with that downslope component to the wind. Sunny skies
are expected with high pressure directly building into the
region. The center of the high passes nearby during Tuesday
afternoon. Used a blend of ecs and gmos for high temperatures,
ranging from the low to mid 60s for most places.

Long term Tuesday night through Sunday
A progressive amplified pattern will dominate this long term
timeframe as vigorous shortwave over british columbia province this
morning digs and tracks across the great lakes region to start this
time period (Tuesday night and Wednesday). Reasonable global model
agreement is noted in tracking this upper low across new england
Wednesday night through Thursday, with ridge building next weekend.

Larger trough over the western states then tracks across the rockies
toward the mid west by late next weekend.

At the surface, high pressure pushes east Tuesday night, giving way
to low pressure and associated cold front that moves across the
great lakes ahead of strengthening upper trough. A coastal low
develops over the carolinas, tracking off the mid atlantic coast by
Wednesday morning. This low deepens as it passes just south,
becoming dominate low as parent low moves across lake ontario
Wednesday night. Norlun trough extends NW from coastal low to
parent inland low Wednesday night early Thursday. This deepening
coastal low then tracks toward the canadian maritimes, with
positional and strength differences noted in the global model suite
late week. High pressure builds next weekend.

Rain will move in ahead of this potent system, with deep lift and
moisture available for moderate to possible heavy rain. A few
hundred joules of elevated CAPE could result in a rumble of thunder
or two. Timing of precipitation looks to be Wednesday morning,
through the afternoon, tapering off in the evening (west to east).

Significant rainfall is expected in a relatively short period of
time, so please see hydrology section for more on this potential
hazard.

A few lingering showers, mainly to the north, are possible
Wednesday night into Thursday in cyclonic flow.

Se winds will increase ahead of this system Wednesday, with strong
gusty winds continuing behind the system Wednesday night and
Thursday. Gusty winds linger into Friday before diminishing ahead of
the building high.

Temperatures near seasonal norms are expected Tuesday night and
Wednesday before falling below Thursday and Friday, in caa.

Temperatures will moderate next weekend thanks to building ridge.

Aviation 09z Monday through Friday
High pressure builds in today, then a cold front passes through
this evening.

Low endVFR to MVFR ceilings are moving through terminals early
this morning as an area of low pressure passes south of the
long island. Conditions will improve mid morning for the metro
terminals and late this morning for eastern terminals as the low
heads away from the area.

W winds this morning will shift to the SW at 5 to 10 kt this
afternoon.

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.
