The episode as NWS OKX wrote it up.
Tropical storm Henri with maximum sustained winds of 60 mph made landfall on the Rhode Island coast, near Westerly, at 12:30pm EDT Sunday, August 22. Henri then continued turning to the west as the storm weakened over Connecticut becoming a depression by evening. Henri meandered towards the Lower Hudson Valley of New York as the storm continued to interact with an upper level trough, before being swept eastward off the New England coast late in the day on Monday August 23, 2021.
Tropical storm force winds were limited mainly to southeast Connecticut. This resulted in a few reports of tree limbs being downed and power outages.
The greatest impact from Henri was flooding due to heavy rainfall in and around the New York City metro, both from a predecessor rainfall event during the evening hours of Saturday, August 21, and then with the circulation of Henri throughout much of the day on Sunday, August 22.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New York, NY wrote its last area forecast discussion before the first event at Aug 22, 6:29 AM EST, 31 minutes earlier.
Area Forecast Discussion
National Weather Service New York NY
729 AM EDT Sun Aug 22 2021
.SYNOPSIS...
Hurricane Henri just south of Long Island will be moving inland
this morning with impacts likely across parts of the local area
today through Monday. A stretch of hot weather is possible for
the middle of next week, followed by a cold frontal passage on
Friday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
**HURRICANE CONDITIONS EXPECTED ACROSS PORTIONS OF LONG ISLAND AND
SOUTHERN CONNECTICUT**
Mesoscale models have been consistent on relatively more
westward track of Henri and relatively more intense winds
across the Twin Forks into Southeast Connecticut associated
around the passage of the center of circulation. There is
enough wind gust potential to keep hazards as is and not drop
any warnings at this time. The NHC track of Henri has it making
landfall near hurricane strength late this morning or early this
afternoon from vicinity of Montauk to Narragansett Bay.
Tropical storm or hurricane force winds are expected along the
south shore, eastern Long Island and across southeast Connecticut,
especially from mid morning onward, with the strongest winds
across the Twin Forks and southeast coastal Connecticut. The
highest winds will likely occur before the middle of this
afternoon. The heaviest of the rain is expected to be to the west
of Henri as the system interacts with an upper level shortwave.
Additionally, some higher amounts can be expected across some of
the higher terrain well inland. The period of heaviest rain is
between 8 am and 2 pm Sunday, where 3 to 6 inches or more may fall
over much of Suffolk County. A flood watch remains in effect for
the entire region with moderate potential for flash flooding and
river flooding today into tonight.
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 Long Island
Sound. The timeline of impacts looks to be this morning through
this evening, with the storm weakening as it moves northward.
Additionally, heavy rain that may occur during times of high tide
could exacerbate flooding along these areas, as there will be a
combination of coastal and fresh water flooding.
Finally, there is the potential for an isolated tornadoes to
move through as Henri makes its approach and landfall. The Storm
Prediction Center has placed southeast Connecticut and eastern
Long Island in a marginal risk for severe storms. Large helicity
values are noted in the models, however surface based instability
could the limiting factor and the reason that the possibility of
tornadoes will not be more widespread.
Please refer to the National Hurricane Center and Hurricane
Local Statement for the official forecast track information.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
Henri will track northwest into southern New England Sunday into
Sunday night, shifting the heavy rain into southwest Connecticut
and the Lower Hudson Valley during through Monday. A widespread
rainfall of 5 to 10 inches is possible as Henri losses forward
speed as it begins to be absorbed into the upper level trough.
Upper level southerly jet extending south of the region into the
Atlantic will help provide a tropical rich moisture source with
layer precipitable waters remaining near 2 inches tonight into
early Monday. The flood watch for the entire region has been
extended in time until 8 PM EDT Monday night to cover the
lingering rainfall into Monday as well as residual runoff and
river flooding anticipated.
The day 2 outlook for WPC has the area in a slight risk for
excessive rainfall. The potential is there for long fused minor
river flooding for down stream rivers such as the Passaic,
Saddle, and Housatonic Rivers. This situation will have to be
monitored throughout the day Monday for updates as much is
dependent on the exact location of heaviest rainfall.
Rain should come to an end late Monday night once the combined
upper level trough and Henri shift northeast into New England.
South winds become more westerly to southwesterly with overcast
skies beginning to scatter through the evening.
&&
.LONG TERM /TUESDAY THROUGH SATURDAY/...
The focus turns to the heat Tuesday through Thursday. H85 temps
warm to around 18-19C in the Tue-Thu period as a ridge builds
into central New York state. The NBM looked a little low based
on these numbers on Wed and Thu, so for those two days went with
the MEX guidance for highs. There is still room for upward
adjustment temp wise. Dewpoints are progged to be in the upr 60s
to low 70s thru the period, yielding heat indices in the heat
advy range for much of the area based on the 2-day criteria with
much of the area being between 93 to 97 heat indices. Moreover
100 degree heat indices are also possible for some areas Wed and
Thu.
A cold front appears on track for late Fri with shwrs and tstms
possible as rain chances increase late into the week. Moisture
may linger into the weekend as the front stalls. Slight rain
chances expected both Saturday and Sunday.
&&
.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
Henri will track over or just east of Long Island today, then
into Northern New England on Mon.
Rain will continue to overspread the area from the east with
heavy bands at times. Cigs will lower to IFR thru the mrng.
Conditions improve late tngt into Mon as the sys tracks nwd and
weakens.
Henri will remain east of the terminals, resulting in backing
winds thru the TAF period. Winds will increase this mrng then
decrease late today as the storm weakens.
...Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Amendments may be needed depending on the exact track of Henri.
Visibilities will fluctuate through the day, especially in
areas of heavy rain.
.OUTLOOK FOR 12Z MONDAY THROUGH THURSDAY...
.Mon...MVFR or lower at times with shwrs and tstms.
.Tue...Mainly VFR but a chance for shwrs and tstms.
.Wed-Thu...Mainly VFR.
Detailed information, including hourly TAF wind component forecasts,
can be found at: https:/www.weather.gov/zny/n90
&&
.MARINE...
Dangerous conditions develop on the waters through today due to
Henri. Hurricane Warnings continue for the eastern waters,
Tropical Storm Warnings for the western sound, western ocean,
and the NY Harbor. Conditions should begin to improve tonight
into Monday. Please refer to the National Hurricane Center for
the official forecast track information.
Waves are expected to build to anywhere from 10 to as much as 20
ft on the ocean waters this morning, with the highest waves
across the eastern ocean zone. Waves across the central and
eastern could build to 10 and 11 ft respectively. Up to 8 ft
waves are possible in the Gardiner's Bay. Waves and seas
eventually decrease tonight into early Monday.
Seas may remain abv 5 ft on the ocean Mon, Tue, and perhaps Wed.
Winds may be close to sca lvls on all waters Mon depending on the
position of Henri. All waters should be blw sca criteria for Thu and
Fri.
&&
.HYDROLOGY...
A Flood Watch continues for the entire area and now extends
through Monday evening. Hydrologic impacts today through Monday
will depend on the track and intensity of Henri. There is the
potential of a widespread 5-10 inches of rainfall today through
Monday evening for the Lower Hudson Valley and parts of Southern
Connecticut and 3 to 6 inches for elsewhere in associated with
Henri. Locally higher amounts are possible. Flash flooding is
possible, especially across NYC, Long Island and Connecticut. NYC
has already picked up 4 to 6 inches in some areas due to a
predecessor rainfall event last night.
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 today. Storm surge warnings are in effect.
Dangerous rip currents are expected through Monday due to
Tropical System Henri.
