What happened

The episode as NWS PHI wrote it up.

A cold front and associated weak area of surface low pressure approached the mid-Atlantic on June 14. A seasonably warm air mass was present ahead of the front, allowing a moderate amount of instability to build over the mid-Atlantic. Moderate to strong wind shear was also present thanks to the presence of a robust upper level disturbance approaching the region. This disturbance, along with the front, provided sufficient forcing for scattered to widespread convection to develop in the interior mid-Atlantic and propagate towards the coast. Some storms became strong to severe in the rather favorable convective environment, posing a primary risk of damaging winds along with some hail. Convection also continued well into the overnight over portions of the area thanks to the good shear and forcing, with convection eventually moving offshore in the pre-dawn hours of the 15th.

What forecasters said that day

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 Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 14, 10:40 PM EST, 8 minutes earlier.

National Weather Service Mount Holly NJ
1140 PM EDT Mon Jun 14 2021

.SYNOPSIS...
Low pressure over eastern Ontario will progress to the east with its
associated cold front passing through our region tonight into
early tomorrow morning. The low should then move northeastward
towards Canada's Maritime Provinces on Tuesday and Tuesday
night. A secondary cold front will on Wednesday evening with
high pressure arriving in its wake for Thursday and Friday.
Another cold front is expected to approach from the northwest on
Saturday and it should pass through our region on Saturday
night and could stall just to our south into Sunday.

&&

.NEAR TERM /THROUGH TUESDAY/...
We've opted to expire Severe Thunderstorm Watch 270 as the
threat of additional severe weather is rapidly coming to a close
across most of New Jersey outside the immediate coast and
portions of southern New Jersey. Severe Thunderstorm Watch 273
remains in effect as the threat now transitions towards
DelMarVa as several storms have moved into an unstable airmass
and undergo rapid intensification of updraft strength.
Anticipate the potential for scattered damage reports across
DelMarVa from these storms. The flooding threat remains for the
metro area in Philly as reports continue to filter in although
there isn't much additional heavy rain expected through the
night.

For Tuesday, the axis of a short wave rotating around the
trough is forecast to pass overhead early on Tuesday afternoon.
As a result, we will keep a chance of showers in the forecast.
There will continue to be some weak instability at that time so
we will also mention a slight chance of thunder.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
The period from Tuesday night through Thursday will feature a fairly
sharp mid level trough extending southward from Quebec over the
eastern states. The main axis of this trough looks to pass through
by Tuesday night resulting in mainly dry weather for this time
period.

Tuesday night into Wednesday, the region will be situated between
high pressure over the midwest and low pressure over Atlantic
Canada. This will set up a dry air advection pattern with lowering
dew points and skies that will generally be mainly clear to partly
cloudy. Lows Tuesday night will be mainly in the 50s to around 60
with highs Wednesday mainly in the 70s to near 80.

High pressure builds in for Wednesday night and Thursday bringing
continuing mainly clear skies with temperatures a little on the cool
side for this time of year as lows will be mainly in the 50s with
highs mainly in the 70s.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
The mid level trough moves out to sea Thursday night with some
ridging from the southwest and west arriving overhead on Friday.
Another mid level trough is expected to progress from Ontario and
the Great Lakes through the northeastern states over the weekend.

At the surface, high pressure is forecast to slide off the coast
Thursday night into Friday. It should remain dry Friday with
readings likely getting into the lower and middle 80s at most
locations as the return flow on the back side of the high begins to
bring warmer air into our region.

A cold front associated with the weekend's mid level trough is
anticipated to approach from the northwest on Saturday before
passing through our region on Saturday night. As a result, we will
mention a chance of showers and thunderstorms at that time for
Saturday afternoon/evening. The front may stall near or just south
of the region Sunday into Monday but forecast details remain
uncertain at this time. Will keep in at least a slight chance of
showers across most of the region for both days.

&&

.AVIATION /04Z TUESDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Tonight...Thunderstorms are progressing eastward this evening
with the potential for some of the to become strong to severe,
and continuing through the early overnight period. Best timing
is generally through 05Z, before the storms exit to the east of
the terminals. Conditions remain VFR behind the storms for
RDG/ABE with MVFR generally from the I-95 terminals eastward
(possibly IFR at times) and continuing through the rest of the
night. Winds will start to trend more to the northwest towards
morning. Moderate confidence.

Tuesday...MVFR/IFR conditions expected across the southern half
of the region to continue through 14-15Z before improvement to
VFR starts to occur for all terminals. Northwest winds around 5
to 10 knots in the morning will increase to 10 to 15 knots with
gusts around 20 knots through the afternoon. Slight chance for
some showers or thunderstorms but confidence to low to include
even a VC at this time. Moderate confidence.

Outlook...

Wednesday...VFR. Northwest wind around 10 knots. High
confidence.

Thursday...VFR. Northwest wind 5 to 10 knots. High confidence.

Friday...VFR. Southwest wind around 10 knots. High confidence.

Saturday...Mainly VFR except restrictions possible in late day
showers/storms. SW winds 10 to 15 knots. Moderate confidence.

&&

.MARINE...
Sub-SCA conditions will prevail through Monday night with seas
running 2-3 ft and southerly winds around 10-15kts. There will
be potential for thunderstorms with locally strong winds tonight
over all waters.

Outlook...

Tuesday through Friday...No marine headlines are anticipated.

Saturday...Southwest winds will increase and could get near SCA
levels by late day.

Rip currents...

The risk of dangerous rip currents is expected to remain
borderline Low-Moderate through Tuesday given 2-3 ft breakers,
and medium-period low amplitude shore-perpendicular easterly
swell. We have issued a MODERATE risk for NJ with a LOW risk
for Delaware for Tuesday.
