Synopsis
High pressure builds across the region today before shifting
offshore on Wednesday. A frontal system moves across the area
on Thursday as a coastal low passes Thursday night into Friday.

A cold front then moves through Friday, followed by high
pressure over the weekend. A cold front tracks across the area
Monday.

Near term until 6 pm this evening
Patchy clouds across parts of the area early this morning will
give way to mostly sunny conditions to start the day as high
pressure continues to build across the region. With weak cold
air advection aloft, temperatures are expected to remain near to
a few degrees below normal. Clouds briefly increase again late
this afternoon into this evening as a shortwave passes north of
the area, but no other impacts are expected.

Short term 6 pm this evening through 6 pm Wednesday
Skies clear tonight the wake of the shortwave, resulting in
good radiational cooling conditions in outlying areas as winds
become light. Overnight lows will range from the lower 20s
across the pine barrens and the far northern and western suburbs
to the mid 30s in the immediate new york city metro area.

The high shifts offshore during the day on Wednesday as weak ridging
builds in aloft ahead of an approaching frontal system. As the flow
shifts around to the south, afternoon highs will be a few degrees
warmer with with plenty of sunshine.

Long term Wednesday night through Monday
Overall general agreement noted aloft with latest model suite, but
important details differ which will have a significant impact on the
forecast. Upper trough moves east, and amount of phasing between
northern and southern streams remains in question. This important
detail will have a significant impact on exact placement track of
sfc low, and depth of sfc low Thu night into Friday. Trend has been
west, closer to the coast, with latest ECMWF and NAM over land with
sfc low track initially.

At this time, it appears that the area will be impacted one way or
another with this trough and sfc low, with showers developing later
wed night or Thu morning. QPF amounts should range from a quarter of
an inch to three quarters of an inch, but higher amounts are
possible.

At this time, do not expect snow, unless precip develops a little
quicker than forecast Wed night. Do have an rain snow shower mix
across the interior, but with corresponding lower pops.

As the system departs, the sfc low deepens as it tracks toward the
canadian maritimes. A cold front crosses the area Friday, and a few
rain snow showers may accompany the front. Winds however will be
quite gusty, increasing Friday, and remaining strong Friday night
into Saturday. Too early to determine with high confidence how high
sustained winds and gusts will ultimately be, but would expect
greater than 30 kt gusts for a time.

Once this vigorous trough pivots east, weak ridge builds, then
quickly flattens as next shortwave dives out of canada, with
lowering heights expected once again across the northeast early next
week. At the sfc, high pressure gradually builds behind deepening
low Saturday. The high passes late this weekend as a cold front
moves through Monday.

Temps should remain around seasonal, but will fall a few degrees
Saturday behind the cold front, caa. Temperatures likely rebound
Sunday and Monday, possibly above seasonal norms.

Aviation 08z Tuesday through Saturday
Vfr through the TAF period with high pressure over the terminals.

Sct to bkn clouds 5-7kft are forecast this afternoon and evening.

Light NW flow increases after day break under 10 kt. Winds gradually
back to the w-sw late early this afternoon and potentially more s-sw
late in the day. Winds diminish and become light and variable after
00z.

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.
