Area Forecast Discussion
National Weather Service New York NY
158 AM EDT Sat Aug 21 2021
.SYNOPSIS...
A stationary front remains in the vicinity through Saturday.
Henri in the Atlantic will be moving northward Saturday night
with impacts likely across parts of the local area through
Monday. A surface disturbance will be in the vicinity Monday
night and Tuesday. A frontal boundary will remain to the north
and west of the forecast area through the end of the week.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Mid-upper level cloud cover continues to stream northward ahead
of the developing tropical system. Given the continued cloud
cover, expect low temperatures to be a few degrees above
climatological normals tonight, generally in the low to mid 70s
across the area. Winds will likely remain pretty light through
the overnight hours into the morning.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Onshore flow develops in advance of T.C. Henri, with lingering
cloud cover and a humid air mass across the area. Diurnal
showers and isolated thunderstorms will be possible once again,
particularly to the north and west of the city where the
southeast flow will allow for an upslope component to aid in
vertical motion.
There will be a high risk of rip currents for Saturday.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
**HURRICANE CONDITIONS EXPECTED ACROSS PORTIONS OF LONG ISLAND
AND SOUTHERN CONNECTICUT**
The main focus continues to be with Henri which is beginning to
make the northerly turn off southeast of Cape Hatteras.
Please refer to the National Hurricane Center for the official
forecast track information. Please refer to the Hurricane Local
Statement for potential impacts.
The latest forecast track takes the center of Henri across
eastern Long Island and then towards southern Connecticut on
Sunday. The ultimate track of Henri will determine where the
strongest winds occur and the amount of rainfall. Tropical
storm or hurricane force winds are expected along the south
shore, eastern Long Island and across southeast Connecticut.
Given the latest track, the heaviest rainfall looks to occur
across Long Island and southern Connecticut, along and west of
the center of the low. The cyclone may begin interacting with
an upper level shortwave over the Middle Atlantic coast, which
could enhance rainfall on the western side of the storm. Storm
surge inundation is also a concern and there is potential for
life-threatening storm surge along the immediate shore of Long
Island, Southern Connecticut, and the Western Sound. The
timeline of impacts looks to be Sunday morning through Sunday
evening, with the storm weakening as it moves northward.
An upper level trough will be over the area Monday night and slowly
track eastward, pushing off the coast by late Monday night into
early Tuesday morning. This will mean a slight chance for showers
Monday night. Not looking at anything widespread as an associated
surface trough will be in nearly the same position as the upper
trough, precluding any strengthening of the system.
With the trough off shore for Tuesday into Wednesday morning, dry
conditions will persist through then.
A frontal boundary then remains to the north and west of the region
through next Friday. There may be an upper level trough that
approaches from the west on Wednesday, that could set off a shower
or thunderstorm in the afternoon, but much of any activity should
remain to the west.
The best chances for any showers and thunderstorms comes towards the
end of the week, as the cold front makes some progress toward the
east.
Temperatures will be warm on Tuesday. Ridging aloft with some height
rises on Wednesday will mean continued warm conditions, leading to
temperatures in the middle 80s to lower 90s on both days. With humid
conditions in place (dew points in the upper 60s to lower 70s), heat
index values across the forecast area could reach the middle to
upper 90s. Slightly more clouds towards the end of the week will
mean slightly lower temperature for Thursday and Friday.
&&
.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
A weak frontal boundary will remains in the vicinity today.
Tropical Cyclone Henri approaches tonight.
Mainly VFR today with Conditions falling to MVFR tonight.
Light and variable winds overnight become SE in the morning
through the day tomorrow with speeds 10kt or less. Tonight,
winds will become easterly and then northeasterly and increase
to 10-15 kt.
...Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Amendments may be needed for wind direction.
.OUTLOOK FOR 06Z SATURDAY THROUGH WEDNESDAY...
.Saturday night...VFR early, then MVFR or lower. Showers
likely with a chance of thunderstorms.
.Sunday...IMPACTS LIKELY FROM TROPICAL CYCLONE HENRI.
.Monday...Mainly VFR. Chance of showers and slight chance of
thunderstorms.
.Tuesday...VFR.
.Wednesday...VFR. Slight chance of thunderstorms in the
afternoon.
Detailed information, including hourly TAF wind component forecasts,
can be found at: https:/www.weather.gov/zny/n90
&&
.MARINE...
Initially sub-SCA conditions through Saturday, before dangerous
conditions develop on the waters late Saturday night through
Sunday due to Henri. Hurricane Warnings have been issued for
the eastern waters, Tropical Storm Warnings for the western
sound and western ocean, and a Tropical Storm watch for the NY
Harbor. Conditions should begin to improve Sunday night into
Monday. Please refer to the National Hurricane Center for the
official forecast track information.
Seas will still be elevated for the eastern ocean zone Monday night,
with 5 ft waves expected. However, waves will be diminishing and
should fall below 5 ft after midnight.
With a lack of a strong pressure gradient, winds and waves should
remain below SCA criteria from Tuesday through Friday.
&&
.HYDROLOGY...
Hydrologic impacts Sun-Mon will depend on the track and intensity of
Henri. There is the potential of 3-6 inches of rainfall late
Saturday night through Sunday night across Long Island and
Connecticut and 1-2 inches further west. Locally higher amounts are
possible. Flash flooding is possible, especially across Long
Island and Connecticut.
No hydrologic impacts are expected Tue-Thu.
&&
.TIDES/COASTAL FLOODING...
There is potential for life threatening storm surge from Henri
across portions of the Long Island coast and southern Connecticut
coast Sunday. A storm surge watch is in effect.
Dangerous rip currents are expected on Saturday and Sunday due
to Tropical System Henri.
