Synopsis
A cold front approaches from the west tonight and passes through
early Wednesday as low pressure develops along the eastern
seaboard. High pressure builds in Wednesday through the end of
the week. A warm front lifts well north on Saturday followed by a cold front
Saturday night. High pressure builds to the west for the beginning
of next week.

Near term until 6 am Wednesday morning
Clouds increase tonight ahead of an approaching cold front from
the west. High pressure moving offshore will allow southerly
flow to advect in low level moisture as developing low pressure
off the florida coast interacts with a northern-stream trough.

This will allow for rapid development of a surface low off the
eastern seaboard.

The cold front interacts with the coastal low with rain
developing late tonight into the overnight from southwest to
northeast. Have slowed down the onset of rain by a few hours
compared to previous forecast with models in decent agreement
regarding precip start time, mainly between 06-09z.

Total rainfall amounts generally between a half to three
quarters of an inch, with eastern long island and eastern
connecticut receiving the higher totals. Other areas will
receive about a quarter of an inch, with lower totals further
west. Felt wpc QPF amounts were a bit too high, so scaled back
for the far eastern zones. This is still about a third of an
inch higher than previous forecast.

Temperatures tonight will fall into the 40s area wide, a blend
of met mav guidance was used.

Short term 6 am Wednesday morning through Wednesday night
Once the cold front passes during the morning, conditions are
likely to quickly improve from west to east during the early
afternoon with drier air ushering into the region. With cold air
advection following the front, the end result will be falling
temperatures throughout the day along with an increase in breezy
nw winds by afternoon.

Long term Thursday through Tuesday
Continued agreement with the operational models for the first part
of the long term period. High pressure at the surface, with the
center over the mid-atlantic states, will keep the area dry for
thanksgiving. Cold air advection continues as noted in 12z gfs
soundings, so conditions will be much cooler than Wednesday. Given
forecast soundings and 850 temperatures in the 0 to -4 c range for
much of the area, highs should only reach the lower 40s, which is
below normal for this time of year. Normal highs should be in the
lower 50s. A cold front does pass north of the area, with a wind
shift to the west, then west-southwest by the afternoon.

High pressure pushes off the east coast late Friday into Friday
night as a warm front over the eastern great lakes lifts well north
of the area. Warm air advection doesn't seem to kick in until Friday
evening, so dry and continued cool for Friday, but slightly warmer
than Thursday with highs in the middle to upper 40s.

Another cold front approaches the area late Saturday and passes
through Saturday night. Southwesterly flow ahead of the front will
bring temperatures to normal levels to above normal levels, in the
upper 40s to upper 50s. 12z GFS has trended drier with this run,
which will warrant only slight chance for the entire area as there
isn't much moisture for the front to work with. It may be cold
enough at the start for some frozen or freezing precipitation in
much of orange county Saturday morning, however, it will quickly
change to rain.

A surface trough or secondary weak cold front moves through on
Sunday with a reinforcing shot of cold air. Some instability with
the colder air aloft associated with the upper level trough may
produce some light rain showers across the area, mainly for portions
of long island.

High pressure then keeps the area dry through the beginning of next
week.

Aviation 20z Tuesday through Sunday
A cold front will approach tonight as low pressure moves up the
coast. The front will pass through during Wed morning.

Vfr until late tonight, then rain with the weak low moving up
the coast will spread into the terminals late tonight into wed
morning, with MVFR conds developing by about 10z-11z at first,
then ifr conds at kisp kgon after 12z-13z.

S-sw winds mostly 10-15 kt with gusts up to 20 kt (kisp kgon higher)
should gradually diminish close to and after sunset, to 10 kt or
less by late evening. Winds will shift NW with cold FROPA mainly
early Wed morning, with speeds not picking up until close to midday
in the nyc metros as the rain ends.

Ny metro enhanced aviation weather support...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
