area forecast discussion
national weather service new york ny
326 pm edt Mon sep 25 2017

Synopsis
A broad area of high pressure will remain over the area through
Tuesday. A cold front moves through the region Wednesday night,
followed by brief high pressure building in from the west
through late week. Another surface low and attendant cold front
pass through Friday night, followed by strong canadian high
pressure settling in across the area through the weekend.

Near term until 6 am Tuesday morning
A 1019 high was centered from vt to the N atlc this aftn. This
sfc ridge will remain in place N of the fcst area tngt.

At the same time, stratus and fog hugging the S fork will expand wwd
on the llvl ely component flow tngt. There was dense fog on CAPE cod
last ngt, and with fog favored at the leading edge of a stratus
shield, patchy dense fog was included in the fcst for most of the
area tngt. Otherwise, dry weather and clear skies as aftn CU will
dissipate this eve.

A blend of guidance, which was in good agreement, was used for
temps.

A high risk for rips and a high surf advy remain in effect thru tue
ngt. Nassau and nyc remain out of the high surf advy ATTM with waves
progged to avg blw 7 ft. This would change, particularly for nassau
county, if the swell comes in any higher than what is currently
modeled.

Short term 6 am Tuesday morning through Tuesday night
Maria will slowly track nwd and the sfc high will remain in place
thru the period. This will result in a slight increase in the wind.

Morning fog and stratus is expected to burn off, at least across the
wrn 2 3 of the cwa. Time heights show moisture is shallow, but the
fog and stratus are still out there today, so it is entirely
possible it lasts thru most if not all of the day for parts of ern
ct and li. High clouds will also increase from the sw, so sunshine
where there is not the low stuff will be somewhat filtered. With the
marine influence, the raw model data was blended in for high temps
yielding numbers several degrees blw guidance.

For the overnight, it is still uncertain how much fog will develop
with winds likely staying abv 5 kt or so. Some of the modeling is
producing measurable pcpn across portions of the area. With a lack
of lift across the area, the fcst included patchy fog and dz for the
majority of the area, with more of a mist than thick fog expected
attm. Temps were a blend of the guidance and raw model data.

Long term Wednesday through Monday
With persistent onshore flow, Wednesday morning may initially have
fog and or stratus and perhaps some light drizzle closer to the
coast as moisture remains beneath the low-level inversion.

Conditions will improve through the day with a final stretch of well
above normal temperatures before the cold front moves through from
northwest to southeast in the evening to overnight. Overall the
front is expected to be moisture starved, with very little, if any
precipitation with its passage. Although temperatures on Thursday
will be a few degrees above normal in gusty northwest flow, dew
points will gradually lower through the day as high pressure builds
in, leading to more comfortable conditions. Thereafter, temperatures
will fall to near or slightly below seasonal values as a strong
canadian high builds in from the northwest. Conditions will mainly
be dry, with the exception of Friday night as a weak low passes
through the area.

Aviation 20z Monday through Saturday
High pressure remains across the region through the TAF period.

Vfr conditions late this afternoon, but watching stratus fog bank
off the coast. Stratus and fog will likely make a push across the
terminals from the east this evening and overnight. Stratus and fog
is expected to be more widespread, however timing is uncertain and
could be an hour or two off from current forecast. These subVFR
conditions linger into Tuesday morning, then improve as the
afternoon hours approach.

Light E SE winds 5-10 kt through the remainder of the afternoon
become light variable again tonight into early Tuesday morning.

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.
