Synopsis
High pressure builds to the north this afternoon through the
weekend, and across the canadian maritimes early next week. Low
pressure may pass south and east of the local area during the
middle of next week, followed by a slow moving cold front late
in the week.

Near term until 6 pm this evening
Mid level moisture continues to erode from NW to SE as high
pressure builds in behind a departed cold front. As previously
anticipated, radar returns have thinned out in response upon
approaching the forecast area. Maybe a shower or two early this
afternoon right along the atlantic coastlines, otherwise dry.

Still plenty of mid-upper moisture around for most of the
afternoon, so generally partly to mostly cloudy with more
breaks of sunshine across the NW half of the tri- state area.

Highs in the mid 70s with falling dewpoints.

There is a moderate risk of rip currents at atlantic ocean
beaches.

Short term 6 pm this evening through 6 pm Saturday
The core of the strongest winds aloft push offshore this evening.

The bulk of the middle and upper level cloud cover should follow
with clearing skies. High pressure also builds closer to the
northeast as the upper trough settles over new england. With mostly
clear skies, light winds, and a dry airmass, low temperatures should
fall well into the 50s inland and near 60 along the coast. The nyc
metro may only fall into the middle 60s.

Saturday will feature high pressure and temperatures a few degrees
below normal for this time of year. Highs will reach the middle and
upper 70s. There will likely be just a few to scattered fair weather
clouds as the atmosphere overall is dry through the afternoon.

There is a low risk of rip currents at atlantic ocean beaches.

Long term Saturday night through Thursday
High pressure builds north of the region Saturday night, then
continues to move east into the canadian maritimes through the day
on Monday. This will create an environment favorable for the
development of stratus and drizzle light rain as easterly flow sets
up over the region. Several models indicate the potential for light
qpf during the Sunday-Sunday night timeframe, with the best chances
from nyc on east.

As the high moves offshore on Monday, an area of low pressure
developing along the southeast coast will begin to lift to the
north, while at the same time a trough will begin digging across the
northern plains. Significant differences remain with the timing and
amplitude of the upper trough as well as with the strength, timing,
and track of the low as it lifts north. While the model consensus
continues to track the coastal low south and east of the local area,
it will have to be monitored for tropical development through the
weekend.

A cold front then approaches the area late in the period, although
the timing of this feature remains uncertain due to the
aforementioned differences aloft.

With the potential for plenty of cloud cover, temperatures on Sunday
and Monday will be several degrees below normal, with highs
generally remaining in the mid 70s. Temperatures then gradually
moderate through the mid week period.

Aviation 18z Friday through Wednesday
A cold front settles just south of the region as high pressure
builds to the north.

Vfr through the TAF period.

Any lingering scattered light showers will taper off and
pass south of the region. Mid and high clouds are also expected
to move south and skies will become clear tonight.

Northerly winds around 10 kt will lighten and may back to the
w NW for a short time in the afternoon, but then shift back to
the N NE by evening around 10 kt.

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.
