What happened

The episode as NWS PHI wrote it up.

In the wake of Tropical Storm Elsa, a warm and humid air mass remained in place over the mid-Atlantic. A cold front approached the region late in the day, triggering a round of showers and thunderstorms. The previous night's rain and some synoptic subsidence behind Elsa limited instability somewhat, and shear was only weak to moderate. This kept much of the convection below severe limits. However, a couple of storms did become severe and produced damaging winds. Storm activity weakened and moved offshore in the later evening hours.

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 Jul 9, 2:17 PM EST, 3 hours 7 minutes earlier.

.SYNOPSIS...
In the wake of Tropical Storm Elsa, a cold front will move through
the area tonight. After a brief lull on Saturday, a warm front will
approach for Sunday in association with low pressure tracking
towards the Great Lakes. This slow moving frontal system may affect
the region for much of next week.

&&

.NEAR TERM /THROUGH SATURDAY/...
A pleasant day has developed across the area in the wake of Tropical
Storm Elsa, with temperatures rising well into the 80s. Winds have
shifted back to southwest, and despite earlier northwest flow
drawing in somewhat drier air, it remains a bit on the humid side.
Overall, a typical summer afternoon.

A shortwave trough will track into upstate New York by this evening.
A well-defined surface cold front sits over west-central
Pennsylvania as of mid-afternoon and will approach our region by
late this afternoon and this evening. Moderate instability (SB CAPE
up to 2000J/kg) has built ahead of the front. We'll also see up to
around 30 kt of bulk shear, not great but enough to allow some multi-
cellular or linear segments to organize. It's tough to gauge
convective potential so soon in the wake of a tropical cyclone.
There tends to be considerable synoptic scale subsidence in the wake
of such storms. The atmosphere was also very worked over at least in
the eastern half of the area by heavy rain last night, so it remains
to fully be seen how well it will recover. But the sounding profiles
this afternoon and evening do look favorable for damaging wind with
good DCAPE developing and some mid-level dry air working in, which
tends to enhance wind damage potential if it is not strong enough to
cut off the updrafts. Could see some small hail also. Latest
satellite and radar trends aren't overly impressive, but some
convection has developed upstream and will continue moving into our
region, where it may organize further.

Overall, think the greatest threat for severe weather will be
east/southeast PA and Delmarva where forcing and instability are
best, but some risk will exist all across the area. The SPC has
added a wind-driven Slight Risk from about the Philly metro
southward. Timing-wise, storms are starting to approach and develop
in the western zones as of mid-afternoon, and should they hold
together would get to the coast towards sunset. The front will move
through during the later evening hours, giving way to a dry
overnight. Winds will shift back to northwest behind the front, and
lows will fall into the 60s.

After an unusually active multi-day stretch of weather, things
finally quiet down on Saturday. Behind the front, drier air will
work in, and a mostly sunny and near seasonable day is expected.
With barely any synoptic flow, the sea breeze will be more prominent
than usual on Saturday, likely making it well inland. The sea breeze
also precludes being able to guarantee a dry forecast. Surface
convergence in the area of the boundary may trigger a couple of
afternoon showers, mainly over New Jersey. This does not at all look
like a widespread event with no synoptic or dynamic support, but
there is enough signal in the CAMs in the face of the expected
mesoscale environment to include slgt chc PoPs over most of New
Jersey. Any showers should dissipate towards sunset, and again,
should be a very nice day on the whole.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
The rain-free weather will be short lived as higher moisture and
warm advection returns Saturday night continuing into Sunday and
Sunday night.  Scattered showers will move into western sections
late Saturday night and continue Sunday and Sunday night with
afternoon/evening thunderstorms.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
A strong surface high over the western Atlantic Ocean will
occasionally strengthen and ridge back across the Middle Atlantic
states. Meanwhile, a trough/low across the Plains and Ohio Valley
region will remain in place through early mid week and then eject
out across the Great Lakes area.

Precipitation will mostly be convective in nature with late
afternoon and evening hours favored.

The heat will return with afternoon temperatures in the lower 90s,
but 80s in the mountains and along the coast.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Through this evening... Prevailing VFR, but tstms are possible at
any of the terminals through about 02z. Any tstms could bring 30 to
60 minute restrictions to MVFR/IFR and gusty and erratic winds.
Outside of any tstms, winds mostly west-southwest at around 10 kt.
High confidence in overall trends, moderate confidence in tstm
potential.

Tonight... VFR with any showers or thunderstorms departing eastern
areas by 02z. Winds shifting from southwest to northwest at around 5
kt, but may be light and variable or near calm at times. High
confidence.

Saturday... VFR. An isolated afternoon shower is possible, but these
should be short duration and limited in both areal coverage and
intensity. Winds northwest at around 5 kt, but may be light and
variable at times. A sea breeze is likely to affect MIV and ACY, and
may reach as far west as the Delaware Valley terminals by evening.
High confidence, except moderate confidence in the western extent of
the sea breeze.

Outlook...

Sat night thru Wednesday...Mostly VFR, but scattered showers and
tstms with lower CIGS/VSBYS possible.

&&

.MARINE...
Through tonight... With winds and seas continuing to diminish, the
Small Craft Advisory has been cancelled for all the waters.
Southwest winds of 15 to 20 kt through this evening will diminish
and gradually shift to northwest tonight with a cold frontal
passage. Seas 3 to 4 ft. An isolated shower or tstm is possible
through 11PM.

Saturday... Sub-SCA conditions are expected. Northwest wind 5 to 10
kt becoming southerly at 5 to 10 kt in the afternoon and evening.
However, winds may be light and variable at times. Seas 3 to 4
ft.

Outlook...

Sunday through Wednesday...Mostly sub-SCA conditions expected.
Scattered showers and tstms Sunday through Wednesday will bring
localized higher winds and seas.

Rip Currents...

In the wake of Tropical Storm Elsa, a High risk for rip currents is
in effect for today. However, beach patrol reports and webcam
observations suggest conditions are already improving. The rip
current risk will fall to at least moderate, if not low levels by
Saturday as winds and seas continue to diminish.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...None.

     024>026.
