Synopsis
High pressure over new england will shift offshore today, with
a weak warm front approaching tonight. A slow moving cold front
will sag south of the region on Monday, followed by the passage
of a weak offshore low on Tuesday. An arctic airmass will
likely build in for the end of the week.

Near term until 6 pm this evening
High pressure tracks over new england, but skies will remain
gray as jet induced cloud cover and pcpn move towards the area
from the ohio valley. The high shifts offshore this afternoon
with the possibility of some light pcpn well N and W of nyc late
this aftn as the entrance region of an upper jet streak with
weak shortwave energy tracks into new england. Soundings
indicate this would fall as snow, with only a coating expected
through 6pm.

Highs are expected to range from mid to upper 30s well inland to
lower to mid 40s near the coast.

Short term 6 pm this evening through Tuesday
Guidance remains in good agreement with an amplifying pattern
developing across the lower 48 early this week as a piece of
the polar vortex breaks off and drops into hudson bay. This will
result in a developing longwave trough east of the rockies with
a high amplitude ridge to the west.

At the sfc, a weak frontal system will track from the mid
mississippi valley into the mid atlantic states by evening and
continue through southern new england tonight. WAA will ensue
tonight ahead of a warm front with temps slowly rising in the
low levels. Pcpn is expected to gradually expand southward,
although nyc and long island may remain mostly dry until
mon night and tue. With the warming low level temperatures any
snow across locations well inland this evening is expected to
change over to plain rain overnight. Less than an inch of snow
accum is expected before the changeover.

Weak low pres continues towards the canadian maritimes on Monday
with its cold front slowly pushing south of the area. Pops
decrease Mon aftn eve as weak ridging moves through ahead of the
next wave of low pres. There is some uncertainty in the track of
this low which will depend on where the energy in the base of
the upper trough tracks and the interaction between this and
additional southern stream energy ejecting from the SE coast.

This will also determine where the axis of heaviest pcpn will
be. Pcpn overspreads the area late Mon night with all nwp
guidance tracking the low S of long island on tue. Colder temps
across northern zones should gradually change the pcpn back over
to snow into Tue morning. Boundary layer temps are progged to
become marginally warm as the pcpn is lifting out which may lead
to a changeover back to the liquid state before ending. At any
rate, boundary layer temps will be marginal across the interior
where accumulating snow is expected late Mon night into tue,
which will result in a wet snow. As such only anticipate 1-2
inches of accumulation. If the axis of heaviest pcpn shifts a
bit further N or the wetter GFS verifies, could be flirting
with advsy level snow. Areas from the ct coast and south are
expected to remain all rain through the duration of the event.

Temperatures are expected to range between 5 and 10 degrees
below normal through tue.

Long term Tuesday night through Saturday
Fair wx Wed with the CWA between systems. An arctic front
however arrives Wed ngt. The GFS and ECMWF both agree on this
timing. Although the models are dry, some snow shwrs cannot be
ruled out. Pops may need to be included in later forecasts.

Dry wx fcst for thanksgiving thru Sat with a 1040 or so high
building in. Temps well blw average on thanksgiving, then moderating
a bit each day thereafter. Rain possible Sat ngt as a pacific sys
approaches.

Aviation 15z Sunday through Thursday
High pressure passes offshore this afternoon as a weak warm
front approaches from the southwest through this evening.

Vfr through this afternoon. There is potential for ceilings 2500-
3000 feet late this afternoon into tonight. Light precipitation
moves into the terminals this evening north of nyc. Kswf may start
off as some light snow, but will transition to rain towards
midnight. Just some light rain is expected for the remainder of the
terminals.

Light and variable winds this morning veer around to the s-se
this afternoon at less than 10 kt.

Outlook for 12z Monday through Thursday
Monday MVFR possible with chance of light rain.

Monday night-Tuesday MVFR or lower conditions possible in
rain or wintry mix Monday night into Tuesday. NW winds gust 15kt
in the afternoon.

Tuesday night-Wednesday MainlyVFR. Low chance MVFR. W winds
g15-20kt.

Wednesday night-Thursday Vfr. NW winds 15g25kt.

Marine
High pressure passing over the waters today will keep conditions
below SCA criteria through tonight.

Winds and seas are forecast to remain below SCA levels through
Wednesday. An arctic front move across the waters Wednesday night
bringing SCA and low chance of gale conditions Wednesday night into
Thursday. Winds and seas then fall below SCA levels on Friday.

Hydrology
Qpf amounts between 1 4" and 1 2" are expected from late this
afternoon into Tuesday. Some of this is expected to fall in
solid form across interior locations. No hydrologic issues are
expected through next Saturday.

Nyc NOAA weather radio station kwo35 (162.55 mhz) will remain off
the air for an extended period of time.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
