Synopsis
High pressure builds to the south overnight and Friday. Low
pressure passes well to the north and east on Saturday. The low
will send a back door cold front through the region Sunday into
Sunday night. The front returns north as a warm front on Monday
ahead of a strong cold front passage late Monday night into
Tuesday. High pressure returns for the middle of the week.

Near term until 6 am this morning
High clouds from a shortwave, moving through the northern
stream, were beginning t move into the northwestern zones as
seen on the mid level water vapor loop. High and mid level
clouds are expected across the northern tier in association of
the shortwave.

Updated the sky cover, winds, temperatures and dew points for
current conditions and trends into Friday morning.

The upper level disturbance moving out of the eastern great
lakes passes to the north overnight. It will pass through dry
with mid and upper level clouds. Another cold night with
temperatures 5 to 10 degrees below normal in the teens to mid
20s.

Short term 6 am this morning through 6 pm Saturday
Upper level trough swings out of the region early Friday with
dry weather continuing as high pressure builds across the south.

A west to southwest flow will advect in warmer temperatures
with highs expected to be near normal, in the 30s to near 40.

Temperatures fall into the 20s and low 30s Friday night under a
mostly clear sky.

Long term Saturday night through Thursday
A split flow pattern is progged across the eastern states this
weekend with a developing storm system and upper trough over the
west. The flow over the northeast will be mainly zonal with a
relatively flat trough to our north. This pattern will yield
above normal temperatures and dry conditions on Saturday as
readings reach the upper 40s and lower 50s. It would not be
surprising if highs end up a few degrees warmer than currently
advertised.

The flat trough to our north will have low pressure traversing
across southeast canada on Saturday into Saturday night.

Trailing this low will be a back door cold front which should
gradually sink southward Sunday into Sunday night as high
pressure attempts to ridge down into new england. No precip is
expected with this front, but temperatures should be held down a
few degrees from those on Saturday. Highs on Sunday will be in
the middle 40s for most locations.

Upper jet stream pattern over the CONUS amplifies further
Sunday into early next week as the storm system over the west
translates into the central states by Monday. Upper ridge axis
moves across the region late Sunday night into Monday as well.

The frontal boundary to our south will gradually lift northward
as a warm front on Monday with low level warm advection and the
ridge axis sliding to the east. A warm nose should develop
between about 750 and 900 mb as SW flow increases ahead of the
approaching upper trough. Main concern with any precipitation
will be for inland locations where surface temperatures are slow
to rise above freezing. The magnitude of the warm advection and
rising heights aloft would indicate any chance of snow is
limited with ptype concerns in the form of light freezing rain
or sleet. This appears to be confined to Monday morning across
the interior. Warmer air continues to move in Monday afternoon
and evening with temperatures getting into the upper 30s and
lower 40s, changing any mixed precip to plain rain.

There is divergence in model solutions Monday night into
Tuesday on the amplitude of the upper trough as well as the
location of the closed low and track of the surface low. Where
confidence has increased is with the progression of the cold
front. Highest chances for moderate to locally heavy rain
continue to be late Monday night into Tuesday morning in
association with the cold front and best dynamics from the upper
trough becoming negatively tilted. Made some minor adjustments
to pop timing, with a decreasing trend Tuesday afternoon and
evening as the front moves offshore. Highs on Tuesday should
reach the upper 40s and lower 50s.

Cooler air works back into the region for the middle of next
week as high pressure takes over with temperatures near normal.

Aviation 06z Friday through Tuesday
High pressure remains centered SW of the region thru tngt.

Vfr thru the TAF period.

W flow backs slowly thru the TAF period, becoming SW aft 23z.

Outlook for 06z Saturday through Tuesday
Saturday Vfr. Wsw winds g20-25kt.

Sunday Vfr.

Monday Chance of MVFR or lower in -shra. S winds g20kt late day.

Tuesday Ifr in rain. Llws. S winds g25kt morning, W winds g30-
35kt aftn.

Marine
No further updates to the winds and seas at this time, with
conditions remaining below SCA levels overnight and into early
Friday afternoon.

Buoy data across southern long island indicates that winds and
seas have diminished to below SCA levels.

With marginal conditions, occasional gusts to 25 kt, expected
Friday afternoon into late Friday, and low confidence of
occurrence will hold off on issuing another advisory at this
time.

Sca conditions are likely on the ocean waters on Saturday as a
relatively strong pressure gradient develops between high
pressure to the south and low pressure to the north. There is
also a small chance for a few gale force gusts. Have elected to
leave out of the hwo for now as confidence is low and they may
end up only being occasional. A few SCA gusts are also possible
on the near shore waters. More tranquil conditions are forecast
on Sunday and Monday with winds and seas below SCA levels. Winds
increase to SCA levels on late Monday night into Tuesday with a
cold front passage.

Hydrology
Dry through the weekend.

A frontal system passing through late Monday night into Tuesday has
the potential to bring around inch of rain. No significant
hydrologic issues are anticipated at this time.

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.
