Synopsis
Low pressure tracks along the new england coast today, followed
by high pressure building in from the west tonight. A strong
cold front approaches from the northwest Wednesday morning, then
crosses the area Wednesday afternoon and evening. Canadian high
pressure builds in through Friday, then slides offshore into
Saturday. A series of storm system will then impact the tri-
state from late Saturday through Monday.

Near term until 6 pm this evening
Low pressure moves along the new england coast through this
evening. Rain will continue east of the city for the next few
hours along a passage of a middle level trough axis. There may
also be some light precip lingering over SE ct into the
afternoon. Otherwise, mainly dry conditions expected this
afternoon.

Highs today be in the lower to middle 40s inland and upper 40s
to near 50 closer to the coast. These highs will end up a
couple degrees short of normals.

Short term 6 pm this evening through 6 pm Wednesday
The flow aloft should be mainly zonal tonight and with dry low-
mid levels and no shortwaves progged in the flow - it will be
dry, with minimal cloud cover. Winds will be gusty, especially
around coastal sections, so this will help limit the
effectiveness of radiational cooling. Lows should be around 5-10
degrees below normal.

A northern stream trough sinks into the area Wednesday.

Increasing low-mid level moisture in the afternoon will allow
for an increase in cloud cover as the trough builds in. Across
mainly interior portions of the lower hudson valley and SW ct
there could be some mainly isolated afternoon rain snow showers
as the surface cold front reflection of this trough moves
through. Note - there is some sign that there could be negative
vorticity advection at 500 hpa Wednesday afternoon. If this
occurs, then the probability of showers is much less than
currently forecast.

Highs on Wednesday should be around 10-15 degrees below normal.

It will be breezy Wednesday afternoon, with 20-30 mph wind
gusts. This will produce wind chills in the lower-mid 20s by
late afternoon.

Long term Wednesday night through Monday
An arctic cold front moves across the tri-state Wednesday evening
with perhaps just enough moisture for scattered flurries. The
airmass to follow Wednesday night through Thursday will be record
cold for most of the climate sites with readings 20 to 25 degrees
below normal. Breezy conditions are expected for thanksgiving day
with sunny conditions but with wind chills in the teens for much of
the day. Winds diminish Thursday night and will be light on Friday
as a high pressure center shifts through the area. Continued mostly
sunny for Friday, but highs will still be in the order of 15-20
degrees below normal.

Global models still disagree regarding how much longwave troughing
occurs to our west with implications on the track and strength of
low pressure that could bring rainfall during the weekend. Best
chances for rain would appear to be Saturday night, but will leave
in chances for Saturday afternoon and Sunday to account for
uncertainty. Temperatures will rebound to near normal over the
weekend.

There's better agreement with the following system as a closed upper
low moves from the ohio river valley to the eastern great lakes
region on Monday. A primary surface low takes a similar track, and a
secondary low passes over or nearby us Monday night. With this being
7 days away, will go with a 50% chance of rain to cover all of
Monday and Monday night.

Aviation 14z Tuesday through Saturday
Frontal boundary just south of long island will remain nearly
stationary this morning as a wave of low pressure tracks along it.

Light rain showers are expected to accompany the lows passage ending
from W to E between 14z and 17z. A gusty NW flow will then develop
this aftn as the low deepens as it departs and high pressure builds
from the w.

MVFR to ifr will prevail across the terminals this morning. May
be holding on to ifr a few hours too long east of nyc
terminals, but gradual improvement is expected aft 15z (w-e)
withVFR returning 18-22z.

Light northerly winds this morning will back to the NW as the
low passes to the S with gusts in the upper teens to lower 20s
aft 17z. Gusts subside aft sunset.

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.
