The episode as NWS OKX wrote it up.
A warm front approaching the area combined with a strong low level jet ushering in precipitable water values in excess of 1.5 inches, resulted in flash flooding across parts of northeast New Jersey. Newark Airport (3.05 inches) and Teterboro Airport (3.01 inches) received just over 3 inches of rain during the event, with the majority of that rain falling during a three hour period.

Area Forecast Discussion
National Weather Service New York NY
1121 AM EDT Fri May 5 2017
.SYNOPSIS...
A warm front moves in today and north of the region tonight. An
associated cold front then quickly follows late tonight into
Saturday. Weakening low pressure northwest of the region this
weekend moves gradually further northward. An upper low will
remain over the Northeast through the middle of next week as a
series of weak disturbances rotating around it.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Light rain associated with the first upper level wave has pushed
north of the area this morning. Most of the area is now mainly under
a dry slot through late this morning until the steadier rain
over the mid Atlantic begins to move across the area later this
morning into this afternoon. Temperatures and dewpoints and
winds were slightly adjusted to better match observed trends.
The upper level trough approaching with PVA and at the surface,
increasing easterly flow ahead of the warm front approaching from
the south. Boundary layer becomes moist with an overall moist
atmospheric column. Rain continues through the day and will be
heavy at times. Any instability is elevated and is conveyed by
models to develop this afternoon, so have isolated thunderstorms
in the forecast as well. This will probably be seen as embedded
thunderstorms within the rain. Cooler temperature guidance from
the NAM12 for temperatures was used.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
The upper level trough continues to approach. The warm front at the
surface will be moving north of the region tonight. The front will
be part of a parent low that will be slightly deepening as it moves
northward from Western PA to Western NY state. Temperatures are
forecast to actually rise slightly this evening before remaining
nearly constant overnight. Rain continues mostly on the East End
of Long Island. Otherwise, other areas will get periodic light
rain or maybe even drizzle at times. Patchy fog develops early on
and further increases as areas at night in response to wet
grounds and onshore flow.
The remaining weakening low Saturday will be northwest of the
region. With cold pool aloft, this will keep showers in the forecast
from time to time. Some surface instability could develop for
western portions of the region Saturday where temperatures will warm
up more relatively so therefore there is a slight chance of a
thunderstorm for those locations. Temperatures are forecast to be
a few degrees warmer Saturday compared to Friday.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Long term forecast models remain in good agreement as an upper
trough remains over the region through much of the period. An upper
low moves into the northeast and remains nearly stationary across
the Northeast through the middle of next week.
The weekend and first half of next week looks to remain unsettled as
an upper level low moves over the Northeast and remain nearly
stationary. A series of weak shortwaves will rotate around the low,
providing the threat of showers as each ones moves across the area.
Despite the threat of rain each day, it should be more dry than wet
through this period, Especially as we get into Sunday and Monday.
A break in the precipitation is expected Monday night into Tuesday
however, another chance of rain will come on Wednesday into
Thursday.
Temperatures should average at or slightly below average for the
long term with an overall cloudy period.
&&
.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
Low pressure approaches today, sending a warm front towards the
region.
Gusty E winds continue through the day, gusting 20-30 kt,
strongest along the coast. Gusts may weaken a bit late this
afternoon as winds veer to the SE. Low level wind shear
expected most terminals into the afternoon.
Conditions continue lowering to IFR as rain overspreads the
terminals. Pockets of +RA along with only isolated thunder are
possible with heavier showers. Any thunder coverage is forecast
to be quite low so it is not mentioned in TAFS at this time.
IFR continues through the afternoon. Ceilings lower to LIFR late
in the day and should continue into the night. Some uncertainty
in visibilities this evening/overnight, but LIFR in FG is
possible.
