Synopsis
High pressure over the region weakens tonight. A cold front then
approaches on Wednesday and passes through during the late day to
early evening hours. High pressure then builds to the southwest,
then south of the tri-state through Friday. A cold front
approaches Friday night, then crosses the area on Saturday,
followed by yet another high building to the southwest and south
through Monday night. A warm front crosses the area next
Tuesday.

Near term until 6 am Wednesday morning
Quick update to speed up the eve temp drop. Otherwise the fcst
was on track. A zonal flow aloft will continue tonight with weak
high pressure over the area. Dry weather continues with some
cirrus moving through. Lows ranging from the upper 40s in the
city to the mid 30s in some of the outlying suburbs. Can't rule
out patchy frost for some these colder spots, but without the
likelihood of a clear sky and calm winds, will not include it in
the forecast at this time.

Short term 6 am Wednesday morning through Wednesday night
The upper patten amplifies with a longwave trough axis approaching
the region and passing through Wednesday night. An attendant cold
front moves through during the late-day early evening hours.

Moisture with the front isn't very deep, but enough to warrant low
chances of showers north and west of the city during the
afternoon early evening.

A tightening pressure gradient and cold air advection will bring
increasing winds and gusts Wednesday night. The wind will prevent
radiational cooling, however the cold air advection will still
manage to knock the temperatures down into the low-mid 30s across
the northern suburbs. Lows in the mid and upper 30s are expected for
most other spots, with the city averaging around 40.

Long term Thursday through Tuesday
Deep layered ridging builds over the area Thursday and Thursday
night, with its axis sliding offshore on Friday. There should
be sufficient subsidence under the ridge to have minimal cloud
cover and dry conditions during this time frame. Low level cold
advection on Thursday will limit highs to 10 to 15 degrees below
normal - with temperatures mainly from the lower 40s to around
50 across the region.

Lows on Thursday night will run around 5 to 10 degrees below
normal. Interior portions of the lower hudson valley and S ct
could see lows around freezing for the first time this fall. If
trends hold, freeze watches and possibly warnings could be
needed for at least parts of that area.

Sw flow setting up in the afternoon should allow temperatures
to moderate on Friday, but still should end up around 5 degrees
below normal.

A 700-500 hpa shortwave and associated vorticity maxima
approach from the west Friday night and cross the area on
Saturday. There should be sufficient lift for scattered showers
across most of the region ahead of this feature - mainly late
Friday night Saturday morning.

A full latitude trough then builds in Saturday night and
Sunday. Have slight chance pops only on Saturday night with the
best dynamics. For now have gone dry on Sunday, but depending on
exactly how cold the low level cold pool is, could end up with
some isolated showers sprinkles.

Northern stream shortwave ridging builds over the area Sunday
night, followed by a northern stream shortwave trough passing to
the north on Monday. Associated subsidence should keep things
dry Sunday night, and the best dynamics should stay far enough
to the north, that when coupled with dry low levels, Monday
should be dry as well.

Continue to have fast flow aloft Monday night-Tuesday as the
region remains on the southern periphery of a northern stream
long wave trough. For now it appears that the low levels should
be too dry to support any precipitation, however with passing
shortwaves progged and low level warm advection do introduce
slight chance pops from N to S late Monday night and Tuesday. It
could be cold enough late Monday night, that if there is any
precipitation well NW of nyc, it could be possibly mixed with
snow.

Temperatures should be above normal Friday night and near normal
Saturday. Temperatures should then be below normal through
Tuesday.

Aviation 00z Wednesday through Sunday
Vfr as high pressure builds to the south tonight, followed by a
cold frontal passage on wed. W winds will start to increase
ahead of FROPA by 13z-14z, then veer wnw and gust either side of
30 kt after 18z. Peak wind gusts could be a few kt higher than
prevailing fcst.

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.
