Showers and thunderstorms developed in the vicinity of a stalled frontal boundary. With weak steering flow and precipitable water values approaching 2 inches on the 12Z Upton sounding, this resulted in widespread flash flooding across portions of urban northeast New Jersey during the mid to late afternoon hours.

The episode as NWS OKX wrote it up.
Showers and thunderstorms developed in the vicinity of a stalled frontal boundary. With weak steering flow and precipitable water values approaching 2 inches on the 12Z Upton sounding, this resulted in widespread flash flooding across portions of urban northeast New Jersey during the mid to late afternoon hours. Rainfall totals include 2.28 inches recorded by the Newark Airport ASOS and 2.17 inches reported by a COOP observer in Harrison. This rain fell across an area with wet antecedent conditions as a result of several rounds of heavy rainfall during the previous week to week and a half.
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 Jul 17, 1:23 PM EST, 42 minutes earlier.
Area Forecast Discussion
National Weather Service New York NY
223 PM EDT Sat Jul 17 2021
.SYNOPSIS...
A stationary front across the northern portions of the area
will lift slowly north as a warm front today. A weak cold front
will then slowly approach from the west tonight and move across
on Sunday, and pass slowly east on Monday. Weak high pressure
builds in Tuesday with a surface trough developing inland late.
Another weak frontal boundary will approach on Wednesday. Weak
high pressure will then build in for the end of the week.
&&
.NEAR TERM /THROUGH TONIGHT/...
Severe thunderstorm watch in effect until 11PM for Northeast NJ, the
Lower Hudson Valley, NYC, Nassau County NY, and Southern Connecticut
from Fairfield through Middlesex Counties. Primary threat will be
damaging winds up to near 60 mph but large hail will be possible as
well with large CAPE in the -10 to -30 degree C layer. With some low
level wind difference between S-SE surface flow and SW flow up to
5kft, there could be an isolated tornado as well.
Flash flood watch remains in effect for Lower Hudson Valley,
Northeast NJ, NYC, Nassau NY and Fairfield CT through tonight. PWATS
near 2 inches will make for torrential downpours with any
thunderstorms that develop. Parallel flow from 800 to 300mb will
enable for training of thunderstorm cells. Height falls going into
tonight will enable for convective coverage to increase and MCS
potential to increase this evening so the flooding threat will be
greatest this evening. Watch area is where there have been
antecedent web conditions due to previous rainfall and less rainfall
needed to get flash flooding.
Heat advisory goes until 8pm for NYC, Northeast NJ, Southern
Westchester NY and Nassau NY. Heat advisory goes until 7pm for
Rockland NY, Northern Westchester NY, Suffolk NY and Southern
Connecticut from Fairfield through Middlesex. Slight
adjustments up with temperature for max temperatures today and
min temperatures tonight. Heat advisory remains in effect for
NYC Metro Area into Northeast NJ including Nassau County as
well. Added other areas where heat indices are getting into mid
90s to near 100 for a large part of the area which includes
Suffolk NY and much of Southern Connecticut as well as Rockland
NY, Northern Westchester NY and Western Passaic NJ. Outside of
these area, mid 90 heat index areas will be isolated and not
enough area of mid 90s heat index values to warrant additional
heat advisories.
Updated POPs through tonight. Main timing for highest POPs for
showers and thunderstorms for NYC Metro, Northeast NJ, Lower Hudson
Valley, and Southwest Connecticut 2PM to 12AM. Farther east for Long
Island and rest of Southern Connecticut, 4PM to 1AM. First round of
showers and thunderstorms from CAMs mid to late this afternoon tied
more with boundary collisions near the surface and high instability
with less shear (closer to 25 kt 0-6 km bulk shear) and focused
along a warm front. However, substantial surface based CAPE will
compensate for lack of shear and result in potential for severe
thunderstorms. Much of the region as conveyed from LAPS surface CAPE
is in the range of 2500 to 3500 J/kg. A highly buoyant atmosphere is
thus present that will enable for rapid development and quick
pulsing of thunderstorms.
Then, the second round of showers and thunderstorms this evening
into the start of the overnight will be ahead of a longer mid level
shortwave trough and in the region with higher positive vorticity
advection. There is forecast to be more 0-6 km bulk shear (near
30- 35 kt) and also focused along a warm front with central low
pressure starting to move in. Instability will become elevated
and will be less than during the afternoon, with models showing
more of the region near 1000 to 1500 J/kg but the increased
shear aloft will keep severe potential going.
Overnight, convection weakens in intensity but there could be a few
strong thunderstorms with heavy rain still a threat also. Coverage
of convection is expected to lower as the warm front lifts farther
north of the region and best convergence area lifts farther north
with it. Added patchy fog for overnight into early Sunday morning
with moisture laden grounds after the convection and some slight
cooling as well as light winds as the low center moves slowly
farther east within the forecast region.
&&
.SHORT TERM /SUNDAY THROUGH TUESDAY/...
The upper trough will remain across the northeast into Monday
and finally shift off the coast late Monday into Monday night.
And the surface low and cold front will be slow to move through
the region, passing east during Monday. So periods of showers
and thunderstorms will be possible through Monday. Weak high
pressure builds in for Tuesday, however a shortwave will dig
into upstate New York Tuesday afternoon with a surface trough
developing. There will be the chance of afternoon thunderstorms,
mainly across the interior.
&&
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
No significant changes to the long term period and stuck fairly
close to the NBM guidance.
A cold front approaches Tuesday night and moves across there
region Wednesday and Wednesday night.
With the front approaching and moving across the area on
Wednesday, will continue to keep the mention of widespread
chance PoP for the entire CWA Wednesday afternoon/evening. High
pressure then builds into the region to end the week. Expect
warm and dry conditions Thursday through Saturday, with high
temps in the 80s to near 90. With dewpoints in the lower 60s,
expect heat index values to remain close to actual temps.
&&
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
A warm front lifts north of the terminals today. A cold front
will approach from the west this afternoon and evening.
Widespread showers and thunderstorms have approached the area
and western NYC terminals early this afternoon and will become
more widespread after 18Z. There will be a threat of continued
thunderstorms after 00Z with high uncertainty in the location of
storms. Most activity comes to an end by about 04Z- 05Z.
MVFR to IFR is possible during thunderstorms, and again
overnight into early Sunday as low stratus and fog develop,
especially at the coastal terminals.
Winds will be light and variable early due to the front stalled
across the area. Winds will gradually veer to the SE/S later
this morning. There is then uncertainty this evening with the
approach of a frontal wave which could cause significant
variability in wind direction, but less than 10 kt.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Timing of onset and cessation of any showers or thunderstorms
Saturday afternoon and evening may be off by an hour or two.
Uncertainty this evening with wind direction. Speeds should
remain less than 10 kt.
.OUTLOOK FOR 12Z SUNDAY THROUGH WEDNESDAY...
.Sunday...Chance of showers and thunderstorms with MVFR or IFR.
.Monday through Wednesday...Mainly VFR. Chance of showers and
thunderstorms each afternoon and evening.

Sub SCA conditions are expected to remain on the forecast waters
through next week with a weak pressure gradient over the waters.

.HYDROLOGY...
A flash flood watch remains in effect for this afternoon and
tonight for northeastern New Jersey, the lower Hudson Valley,
New York City, Nassau county New York, and Fairfield county
Connecticut. Heavy rainfall is likely with widespread 1-2 inch
amounts, with locally higher amounts possible.
For Sunday there is not much steering flow, and while
thunderstorms are not expected to be as strong and coverage not
as much as the previous day, some thunderstorms will be capable
of producing minor flooding.
