Area Forecast Discussion
National Weather Service New York NY
726 PM EDT Sun Sep 25 2022
.SYNOPSIS...
A cold front moves through tonight. A series of weaker cold fronts
pass through the area Monday and Tuesday. Another cold front moves
across Wednesday afternoon into Wednesday night. Strong high
pressure from the Great Lakes then builds in Thursday through Friday
night. By next weekend, the high pressure area will weaken and shift
east of the region into the Northern Atlantic waters. Meanwhile, a
warm front with tropical moisture well in advance of inland low
pressure will approach from the south and west this weekend.
&&
.NEAR TERM /THROUGH MONDAY/...
The first round of showers and thunderstorms passed to the south
of Long Island and over the waters and was less intense then
previously forecast. The area remains dry over the next few
hours, but another round of showers and thunderstorms is likely
between 00-06z from west to east. The threat for severe weather
is still there, with SPC maintaining a slight risk across the
area. The primary hazard / threat would be strong to damaging
wind gusts, with hail as more of secondary hazard / threat.
Current thinking has the shortwave getting further east closer
to midnight, and the cold front getting across the city towards
midnight as well and further east closer to 6z. With clouds
around for a portion of tonight and a persistent SW flow, look
for a more advective type of night. Thus with a lack of
radiational effects, look for temperatures to be just a little
above normal tonight with lows in mainly in the upper 50s to
lower 60s.
The longwave pattern change will continue to evolve with
amplification of the Eastern CONUS trough and the Western CONUS
ridge through Tuesday. Occluded low pressure across SE Canada and
just north of the Eastern Great Lakes will dominate in the short
term. Low pressure will continue to spin NW of the area and rotate a
series of cold fronts / troughs through the area. Another boundary
will pivot through later in the day on Monday and will coincide with
diurnal affects. Thus look for clouds to build, mainly strat-cu by
or shortly before midday. Low end chance, slight chance PoPs is
prudent for Monday afternoon as any low level convergence underneath
steep lower to mid level lapse rates can induce some showers. A
touch of mid level instability along with an inverted profile cloud
lead to a few gusts in association with any shower activity. It will
be quite dry below 5-6 kft, so cloud bases will be elevated a touch,
thus virga is likely with higher base activity. The overall theme
here is a mostly dry day and mostly cloudy afternoon, but the chance
of a shower or perhaps brief isolated thundershower popping up.
&&
.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/...
The WSW flow regime continues Monday night into Tuesday. A weak
inversion is suggested by guidance in the mid levels, thus some
clouds may be around at times. Look for a partly cloudy night and
once again the breeze will stay up enough, especially closer to the
coast to prevent much in the way of radiational cooling. Thus
continuing with the theme of slightly above normal night time temps,
and near normal day time temps into the day on Tuesday. Look for
clouds to build by the early afternoon with daytime heating and
continued steep lower to lower-mid level lapse rates. Broken cloud
cover should prevail by afternoon. For the time being have kept PoPs
minimal and thus keeping the day dry, although cannot completely
rule out a few sprinkles or a brief shower across NW interior
sections. The WSW flow continues with gusts getting to 20 to 25 mph
in some spots.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
As a broad upper trough across eastern NoAm prepares to lift out,
leading mid level vort energy will help push a cold front through,
with a weak sfc trough following late Wed into Wed evening. Strong
high pressure off to the west under mid level confluence in the wake
of the upper trough should then build in for late week.
Guidance then generally agrees on the idea of western Atlantic
ridging expanding NW this weekend, with tropical predecessor
moisture well in advance of any remnant low from now-TS Ian focusing
along a warm front lifting up the coast, but disagrees on the
details. Latest GFS shows mid level confluence holding over the
Northeast which would keep this moisture just south, while the ECMWF
more aggressively builds the Atlantic ridge northward, allowing the
front and associated moisture to move up into the area and possibly
deliver heavy rainfall. The situation is highly uncertain and is
also tied to the future track and intensity of Ian as the storm
moves into and makes landfall somewhere in the eastern Gulf of
Mexico per NHC forecast, so for now the forecast carries 30-40 PoP
going into Sat night and Sunday.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
A frontal system passes overnight, and offshore on Mon.
Mainly VFR thru the TAF period. Shwrs and tstms however in the
01-06Z window will be the exception. TEMPOs carried for this
activity.
SSW winds around 10-15 kt with gusts mainly near 20 kt this
eve. Winds veer to the wsw late tngt, then increase again thru
the day on Mon. Direction will back to the SSW, especially near
the shore, in the aftn. Winds lighten aft 00-02Z Tue.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Amendments possible for the timing of tstms. Strong winds
possible in tstms, but confidence was too low to include in the
TAFs attm.
.OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY...
.Monday Night...VFR.
.Tuesday...Mainly VFR. A chance of showers in the afternoon into
early evening. WSW gusts 15-20 kt day into early evening.

.MARINE...
SCA are in effect for all coastal waters except for NY Harbor
and Western LI Sound through the day Monday. Seas rise to 6-7
feet across much of the ocean, with 5-6 feet seas for the
western ocean. The eastern ocean small craft will remain in
effect longer into Monday night as winds persist a bit longer
and seas are slow to subside below 5 ft. Elevated seas may
linger into early Tuesday morning so small crafts for the ocean
may need to be extended. At this time 4 ft seas are expected
during the day on Tuesday for much of the ocean, although
marginal small craft seas will remain a strong possibility with
the WSW flow continuing preceding the next approaching cold
frontal boundary towards Tuesday eve / night.
With WSW to W flow 15-20 kt for Tue night into Wed, some 5-
ft seas are possible during that time on the outer coastal
ocean waters E of Fire Island Inlet Tue night into Wed AM.
&&
.HYDROLOGY...
There is low potential for heavy rainfall next weekend,
depending on the future track and evolution of the remnant low
of Ian, western Atlantic ridging, and an associated warm front.
It is much too early to say more than that since the situation
is highly uncertain and may not even occur, so for now it is
just something to monitor through the week. Any heavy rainfall
would be beneficial in relieving ongoing moderate to severe
drought conditions that exists across the area.
&&
.TIDES/COASTAL FLOODING...
There is a high risk of rip currents Monday with an increasing
southwesterly flow and waves 5-7 feet at 7-8 seconds. There is
currently a moderate risk rip currents on Tuesday as waves decrease
somewhat with a lingering 7 second swell.

A National Weather Service storm survey team, in |coordination with Suffolk County Fire Rescue and Emergency |Services has confirmed an EF0 tornado in the Mattituck area of|Suffolk County NY.
Based on analysis of the storm survey findings and OKX dual pol |radar reflectivity, velocity and derived data (including a |tornadic debris signature), it was determined that an EF0 tornado|first touched down at Juniper Hill farms around 1117 pm, damaging|a greenhouse and downing a couple of large trees on the property.
The tornadic circulation likely lifted or skipped along as it|tracked east northeast across a one mile stretch of remote wooded|area, before touching down and shearing several tree tops and|large limbs in the vicinity of Cottage Way, Walnut Place, and |Lipco Road, between Sound Avenue and Old Sound Avenue. Peripheral |straight line wind damage to a large tree was noted near Shirley |Road and Horton Avenue to the north of Sound Avenue as well.
The tornadic circulation likely skipped east northeast in the|vicinity of Old Sound Avenue/Main Street over Love Lane and|Wickham Avenue with spotty tree damage noted, before definitively|touching down once again between Wickham Ave and Mary's Road to |the north of Pike Street, with a large maple tree sheared a few |feet from its base, minor siding and roof damage, and leaf |splatter on the west and south sides of homes. This most |prominent damage path, about 50 to 75 yards in width, continued |across Mary's Road, where 3 evergreen trees were snapped at their |base in a convergent pattern (the 2 southernmost trees laying in a|northeast direction and the northernmost tree laying in a |southeast direction). The tornado continued eastward across the |Mattituck-Cutchogue Jr/Sr high school track, twisting and damaging|a large scoreboard, overturning metals benches, and laying down a|100 ft section of wind fence on the north side of the adjacent |tennis courts in a northerly direction (again consistent with a |convergent wind pattern). The tornado then continued east over the|high school, ripping up large sections of asphalt roofing |material over one of the main buildings. The damage across the |high school grounds was the most severe along the path, consistent|with tornadic winds of 75 to 85 mph.
The tornado then exited east over an area of homes on Village |Lane, causing significant tree and fence damage to several homes, |before likely lifting around 1120 pm as the rotating storm |continued eastward over the farm fields and vineyards that lay to|the east. No visible damage was noted to the east of this point, |marking the presumed end of the tornado path.
Numerous large trees down, including a very large Oak Tree split near its base along with a metal fence blown down behind tennis courts and outdoor scaffolding bent and blown down.
