Synopsis
A cold front will slide south of long island as high pressure
gradually builds in from the great lakes. This high will slide
offshore on Monday. A frontal system will then affect the area
Tuesday into Wednesday, ending with a cold frontal passage
Wednesday night. High pressure will returns for Saturday.

Near term until 6 pm this evening
Canadian high pressure remains to the north of the region as
multiple waves of energy ride along a stalled boundary to the south.

Have increased pops to chance for right around daybreak for some
light rain or sprinkles mainly across nyc and western long island.

Subsidence aloft from the aforementioned high pressure will likely
keep the mid levels too dry and suppress rain chances to areas south.

Rain chances end in the morning as the high continues pushing south.

Clouds will remain through the day keeping high temperatures in the
upper 60s to lower 70s, a few degrees below seasonable.

A generally low risk of rip current is expected on Sunday with
mainly 1 ft swells, with a 2 ft ese wind wave.

Short term 6 pm this evening through Tuesday
Upper ridge will shift east through the evening. This will bring
fair weather and a tricky temperature forecast. If clouds across the
northern zones break, there is potential for radiational cooling as
winds remain light under the influence of high pressure. Lows will
drop into the 40s for the interior and into the 50s elsewhere.

Dry and unseasonably cool conditions are expected on Monday. Highs
will struggle to make it out of the 60s with an easterly wind.

Clouds will increase in the afternoon ahead of an approaching
warm front with showers developing overnight. Southerly low
level jet will advect in pw of 1.5-2 inches and could aid in a
period of moderate rain into early Tuesday.

Long term Tuesday night through Saturday
A warm front will then lift across the region on Tuesday.

Showers will develop with the frontal passage on Monday night
into Tuesday along with scattered convection. There might be a
break in the precipitation overnight Tuesday as the warm front
moves north of the region. A cold front will then follow
Wednesday night. With plenty of moisture remaining across the
area there is still a chance of showers and thunderstorms
Wednesday through Thursday. The front should push offshore by
Thursday with drier air moving across the area later on
Thursday. Another fast moving system then moves towards the area
Friday resulting in more showers. High pressure builds across
the area on Saturday.

Temperatures start out below normal for this time of year then
quickly bounce back to above normal for the middle of the week and
remain above normal through Friday before dropping back to
seasonable levels by Saturday.

Aviation 12z Sunday through Thursday
Light rain was skirting the south shore of long island, and kjfk
in particular could see brief MVFR CIGS from this. May also have
to watch for brief MVFR CIGS with onset of ocean sea breeze this
afternoon at klga kjfk, otherwiseVFR.

High confidence in winds as direction shifts from n-se to se-s
this afternoon, with speeds below 10 kt.

Outlook for 12z Monday through Thursday
Monday Pockets of MVFR possible. E winds up to 20-30kt on
Monday.

Tuesday Periods of rain showers with MVFR or lower.

Increasing SE winds abv 30 kt.

Wednesday Showers possible with MVFR or lower at times.

Thursday MainlyVFR.

Marine
Quiet through the weekend. E winds start to increase Sunday night,
with SCA conds developing on the ocean and continuing for an
extended time frame. There is still an outside chance at minimal
gales from late day Mon into Mon night.

The non-ocean waters, in particular the bays and the eastern sound,
may also see wind gusts over 25 kt, but onset and duration there are
less certain.

Sca conditions are likely to continue on the ocean through Thu as a
warm front moves north of the waters and a cold front approaches
from the west. Seas drop below SCA conditions by Friday.

Hydrology
No hydrologic impacts expected through the weekend.

A frontal system could bring locally heavy showers tstms tue
into wed, first via warm FROPA on tue, then again via trailing
cold FROPA on wed. Anticipate only localized nuisance impacts at
this early point.

Tides coastal flooding
Minor coastal flooding possible during the times of high tide
Monday night and Tuesday morning in response to a strengthening
easterly flow ahead of an approaching low pressure system.

Surges of around 1 1 2 to 1 3 4 ft, and locally up to 2 1 4 ft,
are needed for minor flooding.

Equipment
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.

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.
