The radar

The Dover AFB radar (KDOX), 37 km from the middle of the area, began a volume at 00:39 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

Area forecast discussion, Jun 27, 7:35 PM EDT, 1 hour before
Area Forecast Discussion
National Weather Service Mount Holly NJ
735 PM EDT Tue Jun 27 2023

.SYNOPSIS...
Low pressure will slowly pass eastward to our north tonight and
Wednesday, pushing a cold front through our region overnight.
High pressure will briefly dominate Thursday. Another frontal
system is expected to move back in for this weekend and could
linger into early next week.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
730 PM Update...Main swath of storms well ahead of a cold front
continues to move across the I-95 corridor eastward into New
Jersey and also affecting Delmarva. Some of these storms could
still produce locally damaging winds and very heavy rainfall
leading to instances of flash flooding. In general, severe
threat with these storms diminishing but flooding/flash flood
threat likely to persist a bit longer. Behind this round of
storms, there are some more scattered storms farther west
around York and Dauphin Counties in PA but these don't have much
to work with so should stay non-severe even if they make into
farther east into our eastern PA counties. Previous discussion
follows below.

Showers storms expected to diminish around the mid late evening
time frame while also moving off the coast. This should put an
end to the severe weather threat by around 9 PM or so with flood
threat, however, potentially lingering into the overnight due
to response time on our gauges. The good news is though that the
cold front to our west will finally move through overnight
which is why we don't expect it to remain as active as last
night was. Expect lows to drop into the 60s. Patchy fog may
develop where clouds break and winds become light.

Upper level trough will pass overhead in the wake of the surface
front for Wednesday. With a drier air mass moving in and loss of
surface forcing, don't expect coverage like today's (and nothing
like yesterday's) but some isolated to scattered showers and
thunderstorms expected with the upper level cold core during
the afternoon with the best chances for this being over NE PA
into NW NJ and lower chances farther south and west. Otherwise,
overall a cooler and less humid day is expected, with highs in
the upper 70s to lower 80s and dew points falling into the lower
to mid 60s.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
A dry day is expected Thursday as upper ridging builds behind the
departing H5 trough. Under mostly sunny skies, temperatures should
climb to near normal (low/mid 80s) as weak high pressure arrives.
Dew points will remain moderate (mostly low 60s) so not a bad day
overall. Beyond that, the ridge from the SW gets squashed back to
the south as H5 flow across the Plains and Midwest strengthens. A
weak low starts to form across the Great Lakes and a wavy front
develop across our area. Scattered showers and tstms will occur with
this set-up with chance pops as early as Fri afternoon. The last day
of June will have temperatures a couple degrees above normal and an
uncomfortable feel as dew points begin to climb back towards 70
again.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A mostly unsettled pattern for the weekend and into early next week.
The wavy front remain close to our region and with some short waves
embedded in the west-southwest H5 flow aloft. We will carry high
chance or low likely pops for both Sat/Sun. but then scale things to
chance pops for Mon/Tue. A few models (12Z GFS) are showing a trough
exiting the coast Mon night/Tue with the possibility of a dry July
4th for the area. This is a bit far off in the process to have much
confidence in it happening. We'll keep the NBM's small chance pops
for Tue attm. The showery periods Fri thru the weekend will mostly
be late afternoon/early evening time periods, with plenty of dry
periods between.

Temperatures will continue to be mostly normal or perhaps a few
degrees above for the period. It'll be humid thru the period with
dew points in the upper 60s/low 70s much of the time.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

Through tonight...Another round of showers/storms moving through
the TAF sites but will move out by around mid evening. Sub VFR
conditions overnight with MVFR conditions expected for all sites
(mainly due to cigs) and IFR likely for PHL/PNE/TTN/ABE. Winds
becoming light and variable but eventually trending towards SW/W
overnight in the wake of a cold front as it moves through. Moderate
confidence overall.

Wednesday...MVFR conditions from overnight mist/low stratus
could linger for a time into the morning with mainly VFR for the
afternoon except for brief restrictions in any showers/storms.
Best chances for showers/storms will be at ABE and TTN.

Outlook...

Wed night/Thu/Thu night... Mostly VFR. Patchy pre-dawn
   fog possible. Medium/high confid.

Fri... VFR then a chance or showers/tstms late. Lower conditions
   possible. Medium confid.

Fri night thru Sunday... Mostly VFR but scattered showers/tstms with
   lower conditions possible. Low/medium confid.

&&

.MARINE...
The Small Craft Advisory has been cancelled for our southern two
ocean zones but remains in effect through tonight for our
remaining zones over the ocean, mainly for seas 4 to 6 feet.
For Wednesday, the trend in seas will continue to be generally
downward but this will be slow meaning our waters off the coast
of NJ could stay around SCA levels much of the day. Finally,
more showers and storms are likely over the waters for the
evening and overnight period tonight and these could bring
locally higher winds/seas.

Outlook...

Wed night thru Friday... sub-SCA winds and seas expected. Fair
weather Thu and a chance of showers/tstms later Friday.

Fri night thru Mon/Tue... sub-SCA conditions with daily chances for
showers/tstms favoring the late afternoon/evening hours. Winds and
seas higher near tstms.
