The episode as NWS OKX wrote it up.
Tropical Storm Fay tracked northward along the New Jersey coast before passing west of New York City. Several rounds of heavy rain occurred over the New York City metro area as the storm approached. This rain developed in a tropical airmass, with precipitable water values over 2 inches, resulting in numerous reports of flash flooding. Rainfall totals ranged from 1-3 inches across northeast New Jersey, with the ASOS in Caldwell, NJ reporting 2.75 inches, Newark Airport reporting 2.68 inches, and Teterboro Airport reporting. 2.62 inches.

Area Forecast Discussion...CORRECTED
National Weather Service New York NY
234 PM EDT Fri Jul 10 2020
.SYNOPSIS...
Tropical Storm Fay will move northward along the Mid Atlantic
coast today before making landfall near New York City tonight
and continuing north into the Hudson Valley by Saturday morning.
A series of weak fronts will then cross the area through mid
week.
&&
.NEAR TERM /THROUGH TONIGHT/...
Tropical Storm Fay continues to track slowly towards the area
this aftn. Fay will make landfall tonight in the New York City
area and continue north into the Hudson Valley by early
Saturday. Please refer to the National Hurricane Center for
the latest track and forecast details for Tropical Storm Fay.
No changes to winds have been made since the 15Z update. Next
wind update will be with the 21Z Hurricane Center advy.
Rain will continue to impact the area this aftn and eve, with
bands rotating in from the ocean. With precipitable water values
increasing to 2-2.5 inches and tall skinny CAPE, flash flooding
will be possible into this evening as the heaviest rain moves
across the area. The Flash Flood Watch remains in effect, and
WPC continues to include the entire forecast area in a slight
risk for excessive rainfall.
In addition to the flash flood potential, the Storm Prediction
Center has placed much of the area in a marginal risk for severe
weather, with a slight risk along the immediate coastline.
Increasing low level shear as Fay approaches will lead to the
potential for damaging winds and possibly a few tornadoes in any
thunderstorms that are able to develop. The greatest threat may
be in the 00-03Z time period invof the sfc low as it passes
thru the area.
In terms of winds, east to southeast flow will increase across
the area through this eve. Gusts up to around 50 mph possible.
The strongest gusts are expected across NYC, wrn Long Island,
and wrn coastal Connecticut. Winds will then diminish overnight
as Fay moves off to the north.
There is a high risk of rip currents at Atlantic Ocean beaches
thru tngt.
&&
.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
Despite the exit of Fay, a moist airmass will remain in place and
allow for destabilization during the day. At the same time, an upr
trof will approach from the w. As cin erodes, tstm initiation over
the cwa is likely. The 12Z NAM indicated around 3000 CAPE in the
aftn and eve. The main limiting factor is whether any earlier
convection works over the atmosphere sufficiently. The primary svr
threats will be damaging winds and hail. Severe wording and
damaging winds have been included in the fcst for wrn areas to
highlight the threat.
Any activity is modeled to diminish in the overnight period as
dry air sweeps in at the mid lvls.
The NBM was used for temps. Heat indices will be close to 95 for
much of the area. An advy may be needed based on the 2 day
criteria Sat and Sun.
A high risk of rip currents continues for Atlantic Ocean beaches
on Saturday.
&&
.LONG TERM /SUNDAY THROUGH FRIDAY/...
The mean trough axis will remain fairly stationary near the
region through early next week as it is reinforced by a series
of shortwaves rotating through Great Lakes into New England.
Decent agreement that by mid week this trough axis finally lifts
ne of the area, with heat ridging building into the area for
late week into the weekend.
This setup will have a deep S/SW flow across the region through
Tuesday, with a series of weak troughs moving through the
region. This will spell a very warm and humid pattern with
potential for scattered afternoon/evening thunderstorm activity
as shortwave energy rotates through with the surface troughs.
Timing/location/coverage/intensity of threat will be determined
by timing of shortwaves, which will have to be refined at
shorter lead time.
General agreement with the mean trough axis lifting northeast
of the region Wed, with building heights. If this plays out,
deep WSW flow will advect in the building heat across the
central US, with the hottest airmass of the season for late week
into the weekend. With the region lying on northern periphery
of this ridge and active westerlies across US/Canada border, and
potentially moderate to high instability to work with, an
occasional MCS or organized convective threat rolling through
the area is not out of the question during this period.
The high rip current risk will likely continue into early next
week.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
***TROPICAL STORM CONDITIONS EXPECTED LATE TODAY INTO THIS
EVENING***
High impact event as Tropical Storm Fay tracks across or near
the region. Please refer to the National Hurricane Center for
the latest forecast track information.
Tropical storm conditions expected for the NYC metros after
about 20Z-21Z, with IFR in heavy rain and E winds 25-35 kt with
gusts 35-45 kt. These winds could be more squally in nature as
opposed to steady-state. Conds spread N to the remaining
terminals into this evening, with shifting winds as the center
of the tropical storm passes nearby.
Conds improving and winds diminishing overnight.

.OUTLOOK FOR 12Z SATURDAY THROUGH TUESDAY...
.Saturday...MVFR or lower cond likely in SHRA/TSRA, mostly in
the afternoon.
.Sunday and Monday...Continued chance mainly afternoon SHRA/TSRA,
with MVFR or lower cond possible.
.Tuesday...VFR.
&&
.MARINE...
Tropical storm conditions are expected into tngt, before
improving early Sat. Waves were increased for all waters for the
rest of today and tngt. The ocean is expected to come up to
10-12 ft with the Sound up 5-6 ft attm. Seas may remain abv sca
lvls on the ocean into the middle of next week despite the exit
of Fay. On the protected waters, winds and waves look to remain
blw sca lvls Sat thru the middle of next week.
&&
.HYDROLOGY...
Rainfall amounts associated with Tropical Storm Fay will range
from 1-3 inches, with locally higher amounts possible in any
thunderstorms or heavier rain bands. Flash flooding is possible,
with smaller streams and rivers and urban, low lying poor
drainage areas most vulnerable.
Additional thunderstorms Saturday afternoon could result in
localized heavy rainfall and associated minor flooding of low
lying areas. Otherwise, no significant widespread rain expected
through Fri.
&&
.TIDES/COASTAL FLOODING...
Potential for beach flooding and beach erosion, particularly
during the times of high tide this afternoon into Saturday
afternoon. Localized dune erosion is possible, but threat for
washovers is low.
In terms of coastal flooding, there is a low potential for
minor coastal flood impacts from combined surge and wave set-up.
This will ultimately be dependent on track and intensity of the
approaching low. Generally around 2ft of surge is needed to
reach minor flood thresholds, which is currently not shown in
any extratropical guidance, but a potential SE jet of 20-30kt
and long period se swells could result in some localized minor
flood impacts for vulnerable coastal locales of LI, Jamaica Bay
and lower NY/NJ harbor for the Fri Night high tidal cycle.
