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
High pressure remains across the canadian maritime, new
england and into the northeastern states, and will remain
overnight.

Stratus and fog was over the eastern sections of the cwa,
drifting and expanding slowly to the west with a light low
level east flow. Visibilities have been fluctuating and
visibilities have been remaining generally 1 to 2 miles and at
times even higher. Dense fog is not expected, however,
visibilities at times may lower to 1 4 mile. Issued a special
weather statement to address the fog and potential dense fog
overnight.

A high risk for rip currents 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 03z Tuesday through Saturday
Weakening high pressure remains across the region through the
taf period.

Ifr lifr stratus fog has moved onto long island and SE ct, but
has come to a halt just S of kjfk and has even been showing
signs of eroding on the last few scans of Sat imagery. All
guidance still indicating it does come in, so have pushed back
the timing in nyc a few hours as a result. Stratus is slowly
advancing towards kbdr from the E SE and at the current rate
should be in there between 04z and 05z. Some uncertainty with
how low the vsbys get overnight, but flight category will
already be in the ifr lifr range anyway. These low conds will
continue through 12z and then start to mix out from W to E due
to heating and daytime mixing. Kgon may remain MVFR through the
day with the flow becoming onshore again and then decrease
around 00z again.

Light vrb winds overnight. NE E winds 5-10 kt develop tue
morning and shift to the SE again mainly during the late
morning early aftn.

Outlook for 00z Wednesday through Saturday
Tuesday night-Wednesday MVFR to ifr possible with patchy
fog and or stratus and a low chance of showers.

Wednesday night-Thursday MVFR or lower possible with isolated to
scattered shower activity.

Thursday night-Friday Vfr.

Saturday MainlyVFR, except MVFR possible in any showers.

Marine
No changes at this time.

Stratus and fog, with areas of dense fog, were moving into the
forecast waters from the east and will spread westward through
this evening and into late tonight. Visibilities may fall to as
low as 1 4 nm at times, but will also be generally under 1 nm.

The fog is expected to persistent into Tuesday morning, with
improvement across the western waters first, and may be earlier
than 14z Tuesday. A dense fog advisory has been posted for all
but the new york harbor through 14z Tuesday.

Swell associated with maria will continue to increase thru tue.

A SCA for seas therefore remains in effect thru Tue ngt.

Otherwise, winds will remain lgt thru the period.

Lingering swell from t.C. Maria will likely allow seas to remain
at sca-levels through late week, before gradually subsiding this
weekend as high pressure builds from the north. There will be a
chance for winds around 15 to 20 kt with gusts 25 to 30 kt on
Thursday following a cold frontal passage, but otherwise winds
will remain below sca-levels.

Hydrology
No hydrologic impacts expected the next 7 days.

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.
