Synopsis
High pressure over the carolinas this morning tracks rapidly east
over the atlantic tonight into Tuesday. A cold front passed on
Wednesday followed by high pressure. Another cold front passes
late Saturday into Sunday.

Near term until 6 pm this evening
First snow of the season at the NWS upton office - 240 am est!
530 am update: forecast on track with some minor adjustments to
dewpoints and increase in cloud cover this morning.

Otherwise, moderately strong westerly flow prevails today with
ncep bufr model soundings from hrrrx (version 3) and rapx
(version 4) showing good consistency with the operational gfs.

Momentum transfer supports gusts of 20-25 kt this morning and
then a few kt higher early this afternoon, before winds slacken
by late afternoon.

The light rain snow showers have dissipated per all high
resolution models. Bands of strato-cumulus are around this
morning though, but expect them to dissipate to mostly sunny by
noon.

Used a blend of GFS nam and ECMWF mos, which showed little spread,
for temps.

Short term 6 pm this evening through 6 pm Tuesday
The high moves off the mid atlantic coast tonight as low level
flow backs to sw. Expect a mainly clear night - seasonable.

Still a fairly strong pressure gradient. Thus, do not expect
much in the way of boundary layer decoupling outside of the
normal locals. Used the warmer GFS mos and warmed it manually
outside the ny metro area. Even this may be too low.

Tuesday sees gusty ssw flow as the cold front approaches from the
west - still mostly sunny. Used the warmer ECMWF gfs mos
resulting in about 5 degrees above normal.

Long term Tuesday night through Sunday
Nwp in good agreement at h5 through the weekend with a fairly
progressive flow. The period starts with deep SW flow as an
upper trough approaches from the west Tue night. There is good
agreement that the best upper support passes N and W of the
local area on wed. Upper pattern then briefly flattens before
a weak shortwave passes through on thu, followed by another on
fri. Brief ridging again builds in for Fri night with yet
another trough for sun.

At the sfc, return flow across the area Tue night will result in
steady to slowly rising temps overnight with near normal temps
on wed. Developing low pres over the SE coast will gradually
lift up the eastern seaboard as a cold front approaches from the
west. Rain expected to move in late Tue night although there is
some uncertainty in the westward extent of the pcpn shield.

Most of the rain associated with the front appears to dry
up lift N of the area where the better upper support is, with
the remainder from the developing coastal low. Have likely pops
mostly confined to eastern areas, but this may extend westward
in later forecasts. 20 00z GFS is much further east than the
remainder of consensus so it has been discounted. Rain should
end by mid aftn Wed as the low pulls away, but it will become
gusty as the low deepens and the pres gradient tightens.

High pres then builds into the area with dry and cool weather
through Fri night. Temps expected to avg 5-10 degrees below
normal during this time. Another cold front approaches on sat
tracks across the area Sat night with a gusty NW flow expected
in strong CAA on sun.

Aviation 12z Monday through Friday
High pressure builds to the southwest today, passes to the
south, then southeast of long island tonight.

Vfr through the TAF period. Some ceilings around 5000ft are
possible through around 13z.

W-wnw winds will continue through the afternoon. Gusts increase
and becoming frequent after sunrise. Gusts should be around
25-30kt during the day at most terminals. Winds will begin to
back to towards the w-wsw late this afternoon early this
evening as gusts subside. Inland terminals become light and
variable towards midnight.

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.
