What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the long island waters and new york harbor.. A cold front will approach from the north and east, moving south of the waters tonight and into early Sunday. The front then becomes nearly stationary to the south through Monday as high pressure builds in from the north. Another cold front will move through from the north on Tuesday, followed by high pressure building in through Wednesday. A warm front passes on Thu.

Synopsis
A back door cold front approaches from the north and east, and
moves across the region tonight into early Sunday. The front
becomes nearly stationary south of long island through memorial
day as high pressure builds to the north. High pressure will
build into the region through midweek, then low pressure may
impact the region for the end of the week.

Near term until 6 am Sunday morning
Stability is increasing with only slgt chcs now fcst into the
overnight hours. Still expecting a break for several hours
until the next round of precipitation moves in with the
interaction of the back door cold front moving in from the north
to northeast and a pair of shortwaves approaching from the sw
and w. Precipitation will overspread the area generally between
08z and 12z from SW to ne. Instability will be minimal to none
with precipitation mainly stratiform, especially behind the
front.

Short term 6 am Sunday morning through Sunday night
The back door cold front will become stationary south of long
island early Sunday morning, 12z to 15z, and additional
shortwave energy will move through the northeast through Sunday
night into early Monday. Again with little cape, and
instability, precipitation will be mainly stratiform. There may
still be some heavier more convective elements just behind the
cold front Sunday morning with the potentially for heavier
rainfall as these convective elements will be slow moving.

There is a high risk of rip current development at the ocean
beached on Sunday.

Long term Monday through Saturday
A broad area of high pres will build over the region thru wed.

There will be a backdoor cfp on tue. The timing is slightly faster
than yesterday's model suite, thereby suppressing the instability
and chcs for shwrs to the s. The GFS is slower than the ECMWF and
nam, which is why pcpn is initiated closer to the cwa. The fcst
remains dry. The dry wx then holds thru wed, then increasing thetae
could allow for some isold-sct shwrs and tstms on thu. The modeling
is not too aggressive ATTM wrt qpf, as the organized dpva is progged
to remain W of the region closer to the main sys. Pops remain
limited to slgt chc as a result. The main low, which is the remnants
of alberto, is progged to traverse the area Fri and sat. This would
present a better chc for organized rainfall, which could be locally
hvy. The 12z data focuses the low on NRN new england, but this is
likely to change over time, as is did from the prev 12z runs. Pw
around 2 inches is suggested INVOF the low which seems reasonable
based on the subtropical origins. The nbm was used for all but tue
high temps where the warmer superblend was used.

Aviation 03z Sunday through Thursday
A cold front will stall to the south of long island overnight
and Sunday as a few troughs of low pressure move along it.

Light sct showers starting to approach from the SW may reach
some of the western terminals before the main show late tonight
into Sun morning, but no restrictions are expected.VFR to
start with ifr developing generally between 09z and 14z.

Cold front over ct and will drop to the south through 07z with
a light e-ne flow developing. The front stalls south of li
through Sun with rain overspreading the area generally between
08z and 12z. Ifr to lifr conds are expected to prevail through
00z. Widespread steady rainfall may end between 18z and 21z at
nyc terminals with sct showers through the remainder of the
period. E-ne winds also continue through the day although
speeds will increase to 10-15kt with gusts 15-20kt beginning
around 12z.

Outlook for 00z Monday through Thursday
Sunday night Ifr lifr with rain coverage diminishing.

Monday MVFR CIGS in the morning along with slight chance of
light rain, thenVFR.

Tuesday-Wednesday Vfr.

Thursday MainlyVFR.

Marine
With a weak pressure gradient across the waters today and
tonight, winds and seas have remained below SCA levels, and are
expected to remain below through tonight. An increasing NE to e
flow behind a back door cold front, with high pressure building
to the north will result in both winds and seas increasing to
sca levels Sunday morning and continuing into Sunday night,
mainly on the ocean waters, gusts across eastern long island
sound, and the bays of long island may be near SCA levels
Sunday. However expect gusts to be more occasional, and will not
issue a SCA for those forecast waters at this time. Across the
ocean waters have cancelled the SCA that were in effect today
and tonight, and posted a new SCA for the ocean waters Sunday
and Sunday night.

Winds are expected to remain blw SCA lvls mon-thu. 5 ft seas are
possible Mon on the ocean, otherwise they will stay blw SCA lvls
thru thu.

Hydrology
Average basin rainfall amounts through Sunday are expected to be
between 1 3 and 1 2 inch, highest along the coast. Locally
heavy rainfall is possible late tonight into Sunday which could
result in minor urban and poor drainage flooding. There is a low
chance of flash flooding, which could result if there is any
training of heavy rainfall along the frontal boundary.

No significant hydrologic impacts are anticipated Sun night
through thu. There is a low potential for locally heavy rain
fri-sat.

Tides coastal flooding
Water levels may be near minor flood thresholds along the south
shore back bays of nassau county and in western long island
sound with the Sunday late afternoon and evening high tide
cycle. Forcing for increased water levels will be increasing
e-ne flow as a front stalls to the south and strong high
pressure sets up E of new england, along with increasing
astronomical high tides with the full moon on Tue the 29th.

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