The radar

The Philadelphia radar (KDIX), 97 km from the middle of the area, began a volume at 19:25 UTC, the scan nearest the moment this went out.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jul 7, 1:30 PM EDT, 1 hour 51 minutes earlier.

Area forecast discussion, Jul 7, 1:30 PM EDT, 1 hour 51 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
130 PM EDT Fri Jul 7 2023

.SYNOPSIS...
High pressure remains well offshore. A cold front will approach
the area later today and cross the area tonight and Saturday
before stalling nearby. Low pressure will move along the front
Sunday through early Monday. High pressure arrives later Monday
and controls the weather until the middle of next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 120 PM...Line of thunderstorms has formed across the
Appalachian Range near and just west of the Pocono Plateau,
Lehigh Valley, and the Berks-Chester county area. Slow ENE storm
motions may result in localized flooding issues over the next
several hours. The previous forecast remains on track.

Previous discussion...High pressure remains anchored offshore,
with the center of the high almost 400 miles south and east of
Nantucket Island. Onshore flow behind the high will continue to
usher a humid airmass into the region. A cold front approaches
from the west later today and will move over the area tonight.

Another warm and humid day on tap. Highs will top off in the
mid to upper 80s throughout, except in the 70s to near 80 in the
southern Poconos and along the New Jersey and Delaware coasts.
Surface dew points will once again be in the low 70s, resulting
in heat index values in the low to mid 90s, except for the mid
and upper 90s in the eastern shores of Maryland.

That aforementioned surface cold front with mid-level shortwave
energy approaches from the west and will be in eastern
Pennsylvania by late afternoon/early evening. As this
approaches, scattered showers and thunderstorms will develop by
midday, and then showers and thunderstorms will become likely
along and west of the I-95 corridor. Surface-based CAPE values
will increase to 2000 to 2500 J/kg over southeast Pennsylvania
and the eastern shores of Maryland, and from 1000 to 2000 J/kg
over New Jersey and Delaware. PWATs will increase to almost 2.0
inches throughout. Although some thunderstorms may produce gusty
winds of 35 to 45 mph, the main threat will be heavy rain.
Winds from the surface to 500 mb will generally be less than 10
kt, so any storms that go up will not have much movement,
resulting the potential for localized flooding. The Weather
Prediction Center has a Marginal risk for excessive rainfall for
areas along the I-95 corridor, and and a Slight Risk for
excessive rainfall mainly north and west of Philadelphia.

Storms taper off this evening, and it will be another warm and humid
night tonight with patchy fog developing once again. Lows in the
upper 60s to low 70s.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Weak high pressure and what remains of the front (from Friday)
lingers across the region Saturday. The airmass will remain unstable
by afternoon with daytime heating, so more showers/tstms are
expected. The activity will be scattered and with low/mid level
winds still on the light side, severe weather will no be widespread.
Highs will be a couple degrees above normal with mid/upper 80s most
locations.

Sunday will be wet and we will emphasize the potential for excessive
rains and severe weather for the afternoon and evening time frames.
Models agree on a potent short wave rotating around a developing
Canadian upper low and advancing towards the Middle Atlantic. A
surface low will move thru concentrating the rains across our CWA.
One to two inches of rain is possible Sunday. Pops attm will be
categorical for western/northern areas while low likely pops are
expected for Delmarva and the shore areas of NJ. The clouds and
rains will keep temperatures mostly below normal with upper 70s/low
80s for highs across the region.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
The upper air pattern next week will feature a H5 closed low
dropping across southern Canada and extending its influence over the
Northern part of the U.S. Ahead of this low will be one shortwave
which exits Monday before East coast ridging begins Tue and extends
into Thu. More unsettled weather arrives later Thu and will probably
continue into next weekend.

After the showery Sun/Sun night, the upper trough and weak surface
low will be edging away Mon. Since there is no strong ridge
developing right away, we will still be susceptible to the typical
summertime showers/tstms for Monday, but the activity will be
scattered with 30% pops (South) and 40% pops (North). After that,
ridging aloft should keep much of Tue/Wed dry with only isolated
afternoon showers at most. Pops will ramp back to chance on Thu
afternoon as low pressure and its attached fronts arrive from the
west.

Temperatures next week will be above normal more often than not.
The mildest day will be Monday when readings will be near normal.
This time of year that means mostly low/mid 80s for highs. The
Tue/Wed/Thu period will be 'low-end' hot with upper 80s/low 90s most
areas (Cooler for the shore and southern Poconos). The humidity
levels Tue/Wed will be moderate with dew points mostly in the 60s,
but Thu will have an oppressive heat & humidity combo.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Rest of today (through 00Z)...SHRA/TSRA developing across
RDG/ABE and slowly marching east. Storms expected to arrive
across the I-95 terminals by 20Z or so. Localized IFR or lower
conditions, mainly in heavy rain, with 30 kt to 40 kt wind
gusts possible. TEMPO TSRA at KRDG/KABE/KTTN/KPNE/KPHL/KILG.
Otherwise, E to SE winds 5 to 10 kt. Low confidence.

Tonight (00Z through 12Z)...Any SHRA/TSRA taper off in the evening.
A period of VFR conditions, then sub-VFR conditions will develop in
fog/stratus late tonight. Nearly calm winds. Low confidence.

Outlook...

Sat/Sat night... Mostly VFR. Scattered showers/tstms with lower
    CIGS/VSBYS. Low/medium confid.
Sun/Sun night... MVFR/IFR mostly with showers/tstms. Scattered
    severe storms possible. Low/medium confid.
Monday...  Early MVFR/IFR in fog/scattered showers then VFR.
Tuesday... Mostly VFR except in early morning fog.

&&

.MARINE...
Sub-Small Craft Advisory conditions today and tonight. S to SE
winds 5 to 10 kt with seas 1 to 3 ft.

Morning fog with VSBYs as low as 1 nm, but patchy fog with
VSBYs 1 to 3 nm from late morning through tonight. Scattered
showers and thunderstorms will move into Delaware Bay this
afternoon.

Outlook...

Large scale conditions will remain below SCA levels. Scattered
tstms thru the period will create localized higher winds and
seas. Best chances for widespread poor conditions is
Sunday/Sunday night.

Rip currents...

There is a LOW risk for the development of dangerous rip
currents for the New Jersey and Delaware beaches today. Winds
will remain out of the east at 5 to 10 mph. Breaking waves are
forecast to be around 2 feet with a medium period southeasterly
swell.

On Saturday, the risk of rip currents remains LOW. A modest SE
swell around 2 ft or so and a bit more onshore wind 10-15 mph
possible in the afternoon may kick up the waves a bit more and
result in more risk around low tide and locally prone portions
of the coast, but not enough to raise to moderate risk at this
time.

&&

.TIDES/COASTAL FLOODING...
The previous Coastal Flood Advisory has been cancelled. It
appears that the upcoming high tides will not be high enough to
create any further coastal flooding.
