The episode as NWS PHI wrote it up.
Hot and humid conditions existed over the mid-Atlantic on July 6, with a cold front well northwest over the Great Lakes and southern Canada. As temperatures rose into the 90s with dew points in the upper 60s and low 70s, strong instability built over the region. A pre-frontal trough and a fast moving upper level disturbance provided some lift, which helped convection develop by mid afternoon. Convection was initially concentrated over northern Pennsylvania and New York, near the better forcing, but propagated southeastward with time. Shear was weak to moderate but sufficient to allow some storm organization into multi-cellular and linear segments. A number of storms became severe, producing damaging winds and some hail. As storms moved southeast, outflow boundaries moving even further south helped ignite additional convection, some severe, which continued into the early overnight hours. The early overnight convection was also noted to be especially prolific with regard to lightning.

Area Forecast Discussion
National Weather Service Mount Holly NJ
358 PM EDT Tue Jul 6 2021
.SYNOPSIS...
A cold front is expected to remain north of the Mid Atlantic region
for the remainder of the week, while a surface trough remains in
place across the Mid Atlantic region through at least
Wednesday. There remains the potential for Tropical Storm Else
to move near the Mid Atlantic region Thursday night into Friday.
A cold front will finally settle into the region Saturday, then
stall to our south into Sunday. This front may return back
north as a warm front early next week.
&&
.NEAR TERM /THROUGH WEDNESDAY NIGHT/...
A cold front will move across the Great Lakes region and stall out
to our north across across New York and New England areas tonight
through Wednesday and into Wednesday night. Meanwhile, well ahead of
this front, a lee-side/thermal surface trough is in place across the
Mid-Atlantic region and will remain near the area tonight, through
Wednesday and Wednesday night. Several rounds of showers and
thunderstorms will be possible, mainly focused on the late afternoon
and into the evening hours today and again on Wednesday.
For the remainder of this afternoon into this evening, there are two
areas of concern for showers and thunderstorms. The first is an
area of showers and thunderstorms that are in progress and
approaching our area from the north moving through Central NY and
northern PA. These are associated with a strong short wave/vorticity
impulse moving toward the area within the northwest flow aloft.
Instability has built to 2000-3000+ J/kg, but shear remains fairly
weak, generally less than 20-25 knots. Eventhough shear values are
not overly strong, there is an area of 30-40 knots 700-500 mb flow
moving across the area, so the storms could remain strong to severe
as they move into our area late this afternoon into this evening.
Freezing levels and wet-bulb zero heights are fairly high, so while
an isolated severe hail report is possible, any hail that forms will
likely remain sub-severe.
The second area of showers and thunderstorms that may develop is
expected to be across southeast PA and central NJ late this
afternoon and early this evening which would be associated with the
surface trough located across the area. These showers and storms may
not move very fast if they develop, so heavy rainfall could become a
concern. All of this activity will push southward into the evening,
before daytime instability is lost and any remaining showers and
thunderstorms diminish overnight.
On Wednesday, another day of heat and humidity is expected as the
cold front remains to our north, and the lee-side/thermal trough
remains in place. Heat Index values are expected to reach 100-105
degrees or more for many areas again Wednesday, so the areas who's
advisory criteria is 100 degrees or more for heat index will remain
in a Heat Advisory.
There remains a chance of showers and thunderstorms again on
Wednesday. The flow will turn more southwesterly through the day as
ridging builds to our south. Depending on how far north the ridge
noses, it could push the majority of any short wave/vorticity
impulses west of our area during the afternoon and evening hours.
However, we do expect at least our western and northern areas to be
close enough for some enhanced lift to develop, plus with any
instability that develop, showers and thunderstorms could develop
anywhere.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY/...
The cold front starts to drop down from the Great Lakes Thursday and
will likely remain to our west through at least part of Friday
before it starts to push to the east. As the front pushes east it is
likely to stall across our region. We should see some showers and
thunderstorms develop ahead of the boundary as we will be fully warm
sectored on Thursday. Highs on Thursday are likely to reach into the
mid to upper 80s with some spots around 90. Heat index values should
stay below advisory levels.
Tropical Storm Elsa or the remnants of the storm are currently
forecast to pass across the mouth of the Chesapeake Bay and up the
Mid-Atlantic coast Thursday night into Friday. As the system makes
its way towards our area we should see an increase in low level
moisture. With the potential for showers and thunderstorms as the
system passes by, the threat for heavy rain is likely and PWATs look
to be around 2"+ Thursday night. As a result, we have gone ahead and
added the mention of heavy rain to the forecast for Thursday night.
As the system moves off to the northeast, we would expect things to
start clearing out. However, the cold front finally moves into the
region on Friday which will keep us with the possibility of more
showers and thunderstorms.
Temperatures on Friday will remain hot and muggy, as the cooler air
won't arrive until the front starts to cross the area. Highs will
likely be in the 80s across the forecast area.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
We seem to be stuck in a pattern where we see some form of an upper
trough on the weekends with building high pressure through much of
the week. This has left us with unsettled weekends and hot and humid
weekdays. That pattern seems to hold true for this coming weekend
and new week.
The cold front from Friday stalls across the region by Friday night.
The boundary moves little through Saturday and Sunday but should
start to lift northwards as a warm front on Monday. The upper trough
starts to push to the east through the weekend but strengthening
ridging over the Atlantic may slow the forward progress of the
trough. While cooler air is available behind the front there remains
uncertainty as to how far it makes it through our area and as a
result daytime highs through the weekend will be impacted. Once the
front starts to lift northward on Monday, we will see a return to
the southwest flow and warming will occur once again. As we head
into the new week we will see high temps start to reach back into
the 90s and with increasing moisture we will also see the mugginess
return.
With the boundary across the region we will maintain the chance for
some showers or thunderstorms. While it is not likely to be a
washout, we can't rule out that some development will occur, mainly
diurnally driven each day.

&&
.MARINE...
Tonight-Wednesday night...A Small Craft Advisory continues into this
evening and overnight for the Atlantic Ocean coastal waters with
winds expected to gust around 25 knots and seas expected to increase
to around 5 feet. Conditions will subside overnight and remain below
advisory levels through Wednesday. Winds may approach advisory
levels again Wednesday evening. There is a chance of showers and
thunderstorms which may lead to locally higher winds and waves.
Outlook...
Thursday through Friday...Seas and winds will increase in response
to Tropical Cyclone Elsa. Small Craft Advisory conditions are
likely, mainly Thursday afternoon through Friday with seas and
winds dropping back below SCA levels Friday night.
Saturday through Sunday...Sub-Small Craft Advisory conditions are
expected on the area waters.
Rip Currents...
South to southwest winds of 15 to 25 mph will continue for the
remainder of today into Wednesday, although winds will likely
subside overnight tonight. Seas of 4-5 feet will continue for the
remainder of today into Wednesday. A moderate swell of 5-8 seconds,
along occasional longer periods swells around 11 seconds will
continue as well. This should continue to lead to a moderate risk of
enhanced rip currents along the entire coast through Wednesday.
There is the potential for an elevated risk of rip currents Thursday
and Friday due to Tropical Storm Elsa or its remnants tracking off
the eastern seaboard.
