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 Aug 10, 11:29 AM EDT, 2 hours 55 minutes earlier.

Area forecast discussion, Aug 10, 11:29 AM EDT, 2 hours 55 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1129 AM EDT Thu Aug 10 2023

.SYNOPSIS...
A complex area of low pressure will cross our area today, then
a drier air mass arrives for Friday. A weak cold front is forecast
to arrive Saturday night into Sunday, followed by a potentially
stronger cold front later Monday. High pressure then builds in
later Tuesday through Wednesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
The shortwave and weak surface features are presently moving
towards that area. The appearance of echos on radar is showery
with limited organization attm. We expect this to continue into
the afternoon most areas with perhaps more concentration of
cells in a few areas later this afternoon. We'll hold on to the
chance for thunder with some of the fcst CAPE values remaining
low-moderate. Precip should end from W to E during the early
evening. Temps/winds looked fine, minor changes to grids.

Shortwave trough pushes out to sea this evening, which should
allow most if not all showers to end. Cold front from the
northwest (the one currently over the Great Lakes) then moves
through overnight, likely helping to limit any overnight fog
risk as the wind picks up a little and some drier air advects
into the region. Lows generally in the 60s.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Weak surface high pressure will build in behind the front on
Friday across the Northeastern US, making for a quite, dry day
to finish off the work week. Temperatures will be in the mid to
upper 80s across the region in the afternoon with dew points
generally in the low to mid 60s, though should lower a little
during peak heating/mixing therefore it should not feel all that
humid. A west- northwest breeze should remain strong enough to
maintain a land breeze for the beaches.

The next upper-level trough is forecast to be tracking across
the Great Lakes Friday night and this will turn our surface
winds from the south Saturday. Low-level warm air advection will
increase some ahead of this feature and that should boost
afternoon high temperatures Saturday into the upper 80s to
around 90 degrees especially across the coastal plain. The dew
points will also be on the increase and therefore it will be
humid on Saturday. A few afternoon and evening showers and
thunderstorms cannot be ruled out, initially with a lee- side
trough and then with an incoming weak cold front. The main
forcing for ascent however may lift just to our north, therefore
kept PoPs no higher than the chance range.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
Summary...Very warm and humid to start then some cooling and
turning less humid as next week progresses. Some showers and
thunderstorms should return mainly Monday associated with a
stronger cold front moving through.

Sunday...An initial upper-level trough is forecast to be
pivoting across the Northeast with a trailing cold front across
our area. As the upper-level trough quickly lifts away from the
region, the surface front may slow and even stall in our
vicinity. The forcing for ascent looks weak even despite the
lingering front in the area, therefore PoPs were kept at slight
chance or lower for now. It will be a very warm and humid day
with dew points around 70F for much of the area and temperatures
well into the 80s to even some low 90s in the coastal plain. It
will be cooler however in the higher terrain of the Poconos.

For Monday and Tuesday...As a stronger upper-level trough
gradually approaches Monday, a surface front may still be draped
across our region with a weak surface low moving along it. This
could result in some showers or thunder Monday morning, however
the large scale forcing increases by later in the day and at
night as the core of the incoming upper-level trough starts to
arrive. Some guidance has this trough closing off and if this
were to occur then its eastward progression might be slowed at
least some. Showers and some thunderstorms should be on the
increase during Monday, and the intensity of the convection will
depend on any morning activity and then the magnitude of the
instability into the evening. A stronger upper-level system
however will carry stronger shear so this setup will need to be
monitored. The strong cold front should then be crossing our
area Monday night with it shifting offshore to start Tuesday.
This timing could change though depending on the magnitude of
the incoming upper-level trough/closed low, with a decent range
of time between global models still this far out. Temperatures
are forecast to be lowering some with the addition of more
clouds and convection, with the dew points also on the decrease
especially during Tuesday with the passage of the cold front.

For Wednesday into Thursday...A cooler and not all that humid
time is currently forecast in the wake of the upper-level trough
and as surface high pressure builds in. This should result in a
westerly breeze which may help in lowering the dew points some
during peak heating. A dry forecast is currently advertised with
surface high pressure arriving.

Surface high pressure remains in control Thursday, but begins
to erode during the day ahead of the next storm system. Winds
shift southwest once again, allowing dew points to creep up back
into the upper 60s and usher in overall warmer temperatures in
the mid to upper 80s in the afternoon for much of the region
(upper 70s in the Poconos). Precip chances look minimal at this
point, but this storm system bears watching for the end of the
week.

&&

.AVIATION /16Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Thru 0Z tonight...Rain showers with embedded thunder are overspread
the region and should continue thru 0Z or so before tapering
off/moving away. MVFR cigs/vsby look likely, and any heavier
downpours could bring IFR vsby for brief periods. Moderate
confidence.

Tonight...Conditions overall improve back to VFR overnight as
cold front brings cooler drier air into the region and showers
end. Could be a brief period before frontal passage where fog
tries to develop, which could result in reductions to IFR, but
late night looks solidly VFR with NW winds developing and dew
points dropping. Moderate confidence.

Outlook...

Friday...VFR. West-northwest winds around 10 knots, becoming
light and variable at night. Moderate confidence.

Saturday...Some afternoon and evening showers and thunderstorms
possible, mainly across the northwestern terminals, which could
result in locally brief restrictions. Southerly winds around 10
knots. Low confidence.

Sunday...Mainly VFR. Winds becoming westerly around 10 knots.
Moderate confidence.

Monday...A period of sub-VFR conditions along with showers and
thunderstorms possible, especially afternoon and evening. South
to southwest winds 8-12 knots. Low confidence.

&&

.MARINE...
Southerly flow 10-15 kts with gusts 20 kts developing ahead of
a cold front today. Seas build toward 5 ft, but not confident
enough in 5 ft seas to issue a Small Craft Advisory. Right now
they look relatively spotty in nature. Winds shift offshore
overnight and weaken, with seas declining slowly.

Outlook...

Friday through Monday...The conditions are anticipated to be
below Small Craft Advisory criteria through Monday. Some
thunderstorms possible later Saturday and then again Monday.
Winds and seas may build closer to advisory criteria late Monday
as a cold front moves through.

Rip currents...

A southerly wind is anticipated to increase to 10 to 15 MPH
today along the coasts of Delaware and New Jersey. Breaking
waves should be 2 to 3 feet with a long period (around 11
seconds) southeast swell. The expected conditions suggest that
there will be a MODERATE risk for the development of dangerous
rip currents at that time.

A west wind around 10 MPH is expected for Friday. The wind may
become more southerly late in the day. Breaking waves are
forecast to be 1 to 2 feet with a a long period (around 10 to 11
seconds) southeast swell. There is a LOW risk of rip currents
on Friday.
