Area Forecast Discussion...CORRECTED
National Weather Service New York NY
1022 PM EST Tue Jan 9 2024

.SYNOPSIS...
Deepening low pressure over the Upper Midwest tracks into the
eastern Great Lakes tonight, sending a strong frontal system
across the area. The low pressure system slowly moves across
Southeast Canada Wednesday into Wednesday night. Low pressure
slowly moves within Southeastern Canada Thursday and Thursday
night. Another strong low pressure system will likely bring
heavy rain and high winds to the area Friday night and Saturday.
Arctic high pressure builds toward the region Saturday night
into Sunday. Another low may affect the region Monday and
Tuesday.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
HIGH IMPACT EVENT WITH HIGH WINDS AND FLOODING TONIGHT INTO
WEDNESDAY.

- High wind warning remains in effect for all coastal areas
including NYC, Long Island, Connecticut, Southern Westchester, and
Hudson NJ.

- Wind advisory remains in effect for inland areas.

- Storm warning for all forecast waters.

- Flood watch remains in effect for the entire region.

The forecast is still on track with little change in the
forecast expected as the height of the storm system is now
impacting the region. Strong low pressure pushes across the
Great Lakes late this evening, with a secondary low pressure
developing along the Appalachians and moving northeast quickly
with an associated warm front. The warm front lifts up from the
south across the area over the next few hours, followed by a
strong cold front later in the overnight into early Wednesday
morning.

Rainfall amounts with this storm are expected to bring a widespread
2-4 inches, with 1.5 inches already reported in some areas of
NE NJ and the Lower Hudson Valley. Thus the main flooding threat
lingers across inland areas on Wednesday after the bulk of rain
ends due to forecast of elevated rivers and streams above
respective flood stages. The NYC and Long Island part of the
flood watch only goes until Noon on Wednesday but for the rest
of the region goes until 6PM Wednesday evening.

For details with flooding, see hydrology section.

Coastal flooding is expected for tonight and Wednesday mornings high
tides. The highest of the total water levels is expected to be
Wednesday morning. Coastal flood warnings, advisories and statements
are in effect.

For details with coastal flooding, see tides/coastal flooding
section.

High wind warning and wind advisory remain in effect for the
entire region. The main concern with the winds will be a low
level jet maximum of near 100 kt at a height of around 4-8 kft.
Model sounding BUFKIT profiles do not depict a strong
inversion, as the thermal profiles appear to be close to
isothermal. Radar estimated winds just 1-2kft above the surface
are shown to be reach 50-70 kt, with some 80 kt winds at around
1500 ft for eastern coastal sections. Much of this should get
mixed down to the surface through downward momentum transport.
The timeframe for this generally between now and 8-9Z Wednesday.
Currently watching fine lines working up from the south and
southwest from NJ, so if this convective activity holds this
would represent more downward momentum transfer and a damaging
wind threat.

Also, increasing omega and an increasing southerly flow throughout
the troposphere increase the PWATS to well above 90th
percentile climatology values overnight. Models still conveying
PWAT values topping out at 1.4-1.5 inches maximum overnight into
the coastal parts of the region. With some elevated instability
across eastern parts of the region, can not rule out a few
isolated rumbles of thunder with a few positive lightning
strikes already noticed offshore to the S and SE. This has lined
up with the CAMs near term forecast.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
The storm system lifts northeast of the region on Wednesday into
Wednesday night with the cold front pushing east of the region.

An upper level trough will remain over the region on Wednesday,
which may result in some additional rain showers from time to time
on Wednesday. By Wednesday night, the upper trough lifts north
with drier conditions expected. Pressure gradient will remain
tight on Wednesday and will begin to relax Wednesday night.
Gusty westerly flow on Wednesday will be below advisory
thresholds but a localized isolated gust or two to near 45 to 50
mph cannot be ruled out. Most gusts are expected on Wednesday
to be in the range of near 30 to 40 mph. Gusts will continue to
diminish Wednesday night.

Highs on Wednesday will be in the middle 40s to lower 50s, with
highs Thursday in the 40s.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Another strong storm likely impacts the region late Friday into
Saturday with another round of moderate to heavy rainfall, and
strong, to potentially damaging winds, along with a coastal flooding
threat.

Another southern stream trough will be moving onshore of the Pacific
northwest midweek and track across the country, reaching toward the
Great Lakes Region late in the week. With some of the global
guidance the upper trough is becoming more negatively tilted during
Friday, keeping the surface low a little farther to the west. Timing
of the heaviest rainfall and highest winds remains Friday night into
Saturday as a low level jet of 50-70kts moves through the region.
Also, an occluded low will be moving over the region late Friday
night into Saturday morning. Strong lift, and some instability,
along with elevated CAPE up to 500 J/kg will allow for a chance of
thunderstorms. Precipitable waters also increases late Friday night,
up to 1.35 inches, and a period of moderate to heavy rainfall
remains possible. The is the potential for another flooding event as
WPC has placed most of the area in a slight risk for excessive
rainfall. Finally, with the strong winds another high wind event is
also becoming more likely. While there are a few days until the
onset of this storm impacts are becoming more likely.

Strong cold advection Saturday, behind a cold front, will be the
leading edge of an Arctic airmass that will be over the region
Sunday into Monday, with temperatures falling to near or just below
seasonal normals.

After a brief dry period another southern stream system may impact
the region Monday into Tuesday.

&&

.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
***Major Storm System to Impact Terminals Through Tonight***

Deepening low pressure over the Midwest tracks into the Eastern
Great Lakes tonight, sending a strong frontal system across the
area. This is a high impact event with strong winds and heavy rains
now taking place.

Brief LIFR is possible at a few terminals for a few hours, but will
not be the rule, but rather the exception. Otherwise IFR prevails at
most terminals. IFR and MVFR prevails up until the start of the
morning push for the city terminals, with VFR returning by 10z. VFR
conditions will prevail on Wednesday, with a few brief showers which
may briefly result in non-prevailing MVFR ceilings for the mid to
late morning.

SE winds have ramped up reaching 25-30 G45-50kt late this evening,
with the highest at the coastal terminals. These high winds will
take place until the cold frontal passage, which will be from west
to east from approximately 08Z to 11Z. There could be a brief lull
in the winds as the front moves through. Post-frontal WSW winds on
Wednesday 15-22G30-35kt, with possibly a few higher gusts,
especially for the afternoon.

A few isolated thunderstorms remain possible over the next several
hours, mainly for eastern terminals.

...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Amendments may be needed for changing flight categories.

A few gusts above 50kt will be possible until 08Z. Highest potential
for higher gusts is at KJFK.

Isolated thunderstorm possible overnight.

OUTLOOK FOR 0Z THURSDAY THROUGH SUNDAY...

Wednesday night: VFR. WSW winds 15-20G30kt, subsiding to 10-15G20kt
as winds gradually decrease later at night.

Thursday: VFR. WSW winds 10-15kt with gusts near 20kt.

Friday: VFR early, becoming MVFR or lower with rain. Increasing SE
winds late.

Friday Night: MVFR or lower. SE winds 15-25kt G30-40kt.

Saturday: MVFR or lower with rain. SE winds 20-30kt G30-40 kt,
becoming W 20-25kt G30-35kt.

Sunday...VFR. W 20-25kt G30-35kt.

Detailed information, including hourly TAF wind component forecasts,
can be found at: https:/www.weather.gov/zny/n90

&&

.MARINE...
Winds on the area waters will quickly ramp up early this
evening to gales, then to storm force gusts for tonight. Ocean
seas build to 14 to 20 ft tonight into early Wednesday.

Gales are likely Wednesday into Wednesday night, eventually
subsiding to SCA level wind gusts late Wednesday night. Ocean
seas will remain elevated well above SCA thresholds Wednesday
through Wednesday night.

Marginal SCA wind gusts remain possible on the non-ocean waters
Thursday as a strong westerly flow diminishes, and during Thursday
evening gusts fall below advisory levels. Meanwhile, the ocean
waters will have on-going SCA conditions Thursday with winds and
seas diminishing west to east during Thursday night. An increasing
southeast flow ahead of the next strong low will allow for gale
conditions to develop Friday night across the forecast waters. There
is a chance of storm force gusts on the ocean waters Saturday into
Saturday night as gale condition continue on the non-ocean waters.
Gales are likely behind the low Sunday, with conditions gradually
improving Sunday night as high pressure builds toward the waters
from the southwest.

&&

.HYDROLOGY...
Flood watch remains in effect for the entire forecast region from
6PM tonight to 6PM Wednesday for NE NJ, Lower Hudson Valley and
Southern CT. Flood watch remains in effect for NYC and Long Island
6PM tonight until 12PM Wednesday.

WPC has moderate risk for much of the area for Northeast NJ,
Lower Hudson Valley and Southern CT with NYC and Long Island in
a slight risk for excessive rain for this afternoon through
tonight.

A major storm system will bring a total of 2 to 3.5 inches of
rain with locally higher amounts this afternoon into early
Wednesday. The bulk of the heaviest rain will occur tonight.
Some GFS ensemble members indicating possible 4+ inches of
rainfall across some parts of Southern Connecticut.

There will be potential for widespread urban and poor drainage
flooding as well as river and stream flooding. The river and
stream flooding would potentially linger through the day
Wednesday and potentially into Thursday.

Hourly rainfall rates will generally remain between a half to three
quarters of an inch. An isolated area of 1 inch per hour of rainfall
rate is possible but will be quite brief in duration.

Some rivers in NJ are forecast to reach moderate to major flooding
levels.

Hydrologic impacts remain possible Friday night into Saturday, as
the Weather Prediction Center has much of the area in a slight risk
for excessive rainfall, with another round of moderate to heavy rain
possible. One to two inches, with locally higher amounts remains
possible. However, the exact magnitude and extent of the flooding
issues are uncertain this far out.

&&

.TIDES/COASTAL FLOODING...
Significant ocean dunefront damage expected Wednesday.
Widespread minor to moderate coastal flooding with Wed AM high
tide. Localized major coastal flooding will be possible,
especially within the South Shore Bays of Long Island.

NY HOPS Steven Institute surge models actually have went back up
compared to 24 hours ago in terms of the total water level
forecasts.

SE storm force expected tonight into early Wednesday, with a
windshift to west southwest gale likely just before the time of
high tide for most areas. This windshift will likely limit
potential for locally major coastal flooding to just the Great
South Bay of LI. Elsewhere, widespread moderate flooding likely
for southern bays of NYC/LI and eastern bays of LI, and SE CT.
Elsewhere generally minor flooding.

Minor coastal flooding possible for the southern bays of W LI,
and along W LI Sound this evening as E/SE increase towards gale
force.

Along the oceanfront, potential for 15-20 ft surf causing
widespread dune erosion and scattered overwashes Wed AM.
Localized dune inundation/breaches possible where dunes have
been compromised by earlier storm events. 10 to 15 ft breaking
surf expected with Wed PM high tide, and with lower water
levels, expect dune impacts to be lower magnitude and less
widespread.

Coastal flood impacts are possible around the times of high
tide Friday night and Saturday with another deep low tracking
west of the area.
