Synopsis
A weak frontal boundary will remain in the vicinity today. A wave
of low pressure moving along this boundary then passes through
late tonight into Tuesday morning. An arctic front then sweeps
across the tri state area Wednesday evening. Cold canadian high
pressure then builds in through the end of the week with the
potential for wet weather over the weekend.

Near term until 6 pm this evening
The coastal front moved into eastern long island and then down
just east of the new jersey coast at 14z. Temperatures have
risen into the upper 40s and around 50 with the frontal
passage.

Also, the initial was was moving a little farther to the north
and precipitation was just about out of the area, moving
through putnam and northern fairfield counties, with light rain.

So adjusted probabilities to account for this. And then also
adjusted probabilities into this afternoon with the slight
delay with the onset of precipitation with the next wave
approaching from the southwest.

Short term 6 pm this evening through 6 pm Tuesday
The low pressure center moves through overnight into Tuesday morning
while slowly strengthening as a digging upper trough to our west
begins the process of becoming negatively tilted. Still some
synoptic-level lift around with a coupled jet structure shifting
into the region. Still think that the entire area eventually
sees pcpn tonight into Tuesday, but northern zones have overall
better chances and higher QPF potential. Pcpn probably shifts
east out of the tri-state area by noontime on Tuesday. Thermal
profiles support rain for the most part, but parts of the lower
hudson valley will probably see a mix of rain, sleet and snow.

Snow sleet accumulations will be mostly under an inch, but the
higher elevations of western orange county can pick up to around
an inch.

Long term Tuesday night through Sunday
Nwp guidance is in good agreement across north america into thu
however solutions begin to deviate starting Thu night as a series of
upper troughs moving onshore from the eastern pacific traverse the
country. This is leading to vast differences in the forecast for the
weekend across the northeast.

Upper trough axis slides east of the area Tue eve with zonal
flow briefly returning into wed. Strengthening jet streak
diving out of north central canada tonight will result in the
development of vigorous shortwave energy and amplification of
the canadian vortex over hudson bay Tue tue night. While the
strongest dynamics will pass well to the north of the area on
wed, an arctic front will pass through the region Wed eve,
possibly triggering a few snow showers north and west of nyc.

There is also the possibility that once the front taps into the
moisture from LI sound and the atlantic that additional snow
showers could develop, however will need to wait 24 hours to see
if any of the hi res guidance picks up on this.

Windy conditions develop in the wake of the arctic front
continuing into thanksgiving day. H85 temps drop to -18 to -20c
by Thu morning. An unseasonably cold arctic airmass will remain
through Thu night before beginning to moderate on fri. Low
temperatures thanksgiving morning will mostly range in the teens
with lower 20s in the metro area. The combination of the winds
will make it feel like its in the single digits, teens in nyc
metro. High on Thu are not expected to reach the freezing mark,
with 20s areawide, highest near the coast. Wind chills will only
reach the teens across much of the area. The combination of
clear skies and diminishing winds Thu night will allow for ideal
radiational cooling conditions with the coldest temperatures of
the season thus far expected. Single digits are expected across
the interior and in the pine barrens of long island with teens
closer to the coast.

The cold canadian high will shift offshore on Fri allowing a
waa pattern to ensue with moderating temps. High Fri will still
remain 10-15 degrees below normal, but will be near normal on
sat as the next potential storm system moves into the area.

There is uncertainty on how the energy from the troughs moving
onshore out west interacts through the week which will
ultimately determine timing of pcpn. At this point is does
appear to be a liquid event.

Aviation 15z Monday through Friday
MVFR CIGS have meandered across the terminals as a weak boundary
remains across the region. Conditions will improve toVFR
area wide by afternoon and remain that way before conditions
fall back to MVFR this evening and overnight once again. Light
rain will move across the terminals overnight and Tuesday
morning. Conditions will remain MVFR or lower for tomorrow
morning's push.

Winds will remain light and veer from the southwest to the
northeast through the day.

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.
