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 20, 10:35 PM EDT, 3 hours 57 minutes earlier.

Area forecast discussion, Jul 20, 10:35 PM EDT, 3 hours 57 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1035 PM EDT Thu Jul 20 2023

.SYNOPSIS...
A stationary front remains over the area through today
before returning back north as a warm front tonight. A cold front
then passes through the region on Friday. High pressure builds in
from the west on Saturday then weakens and moves offshore Sunday
night. A few weak disturbances may affect us early next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
Severe Thunderstorm Watch #530 is now in effect until 5 am for
most of southeast Pennsylvania, including Philadelphia, and
parts of northern New Jersey.

A line of severe thunderstorms is currently moving through
western New York and western Pennsylvania. This system is on
track to impact Berks county and the southern Poconos around
midnight, and then the I-95 corridor, including Philadelphia and
surrounding suburbs, and northern New Jersey around 2 am, and
then eastern New Jersey thereafter.

These storms are about 2 to 3 hours faster than previously
forecast, and are faster than latest HRRR and 18Z NAM have
indicated. Damaging winds are likely, as well as large hail.
Heavy rain and localized flash flooding is also possible.

Surface-based CAPE values are up around 1500 to 2000 J/kg along
with 25 to 35 kt of 0-6 km Bulk Shear.

By the time early Friday morning arrives, storms will have
moved in with coverage potentially be relatively widespread for
areas near and N/W of the I-95 corridor. By this time, the
strongest upper level forcing should be just moving through with
low pressure centered near Lake Ontario and the system's triple
point over eastern PA with the warm front extending eastward
through NJ and the cold front extending S/W into Maryland and
Virginia. The overall evolution of the convection becomes a bit
more uncertain beyond this time as initial shortwave aloft
swings through to the north and east but the main upper level
trough only chugs slowly east across southern Ontario into
upstate NY. This means that the low at the surface and its
associated fronts should be slow to move east as well. The
upshot of this is that stormy weather is likely to continue
through at least the first half of Friday as initial convection
could even start to train for a time over eastern PA into
northern NJ. Even as this first round should be moving out by
around midday there could be more storms that develop in the
afternoon. It's uncertain though how much instability there will
be due to AM storms so the SPC keeps area in a MARGINAL risk
for severe weather for Day 2 (starting 12z Friday) with a
MARGINAL threat for excessive rain and flooding/ flash flooding
also be indicated by WPC. By the time the system moves through
by Friday evening with winds turning westerly and conditions
drying out, think much of the area could see 1.0 to 2.0 inches
of rain with locally higher amounts. Heaviest amounts should be
in the north. Again, still some uncertainty on this so forecast
will continue to be refined through the day today. The
showers/storms should help keep temps cooler for Friday with
highs mostly in the low to mid 80s except some upper 70s over
the higher terrain where clouds are most likely to remain in
place through the day.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
Cold front will be rapidly pushing off the coast Friday evening.
Still a little uncertainty in timing so held some chance pops early
but back them off below slight chance after 00Z. Otherwise,
clearing, cooler and drying out Friday night. Lows overall will drop
3-5 degrees compared to Thursday night, with 60s across most of the
region.

High pressure slowly builds in Saturday and Saturday night. We'll
see plenty of sunshine, which will help allow temps to rise back to
near the same readings we're expecting Friday (mid-80s), but dew
points will be 5-10 degrees lower, mostly in the low-mid 60s. This
will result in a considerably more comfortable day compared to
Friday.

A weak secondary front passes Saturday evening, ushering in slightly
cooler and drier air. This will help lows drop a few more degrees
compared to Friday night, settling down into the upper 50s to low
60s overall, except still mid-upper 60s in the urban centers and
near the waters. Otherwise, clear skies and light winds will prevail.

Sunday will see continued mostly sunny skies as high pressure
remains in overall control, thought it will be shifting off-shore
with warm advection just beginning later in the day. Thus, expect
highs to nudge back up a degree or two compared to Saturday, but dew
points will do the opposite, so overall, another nice, dry day.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
High pressure will be firmly offshore by Monday, with a return
southerly flow starting to nudge dew points back up, though they
still remain in the 60s. Warmth will build ever so slightly,
tempered by the potential for some afternoon clouds or even a stray
shower or storm as an upper level shortwave moves toward us, but
overall still dry. This pattern more or less continues Tuesday, with
some morning sun followed by afternoon clouds and a stray shower/t-
storm with another upper-level disturbance, but more dry than not
for sure.

By Wednesday, a warm front starts to lift back north of the region,
decreasing the threat of isolated showers/storms as a ridge builds
toward us, but also allowing temps and dew points to creep back up a
few more degrees. Still not quite oppressive for this time of year,
but more uncomfortable than the prior two days, with dew points
mostly in the upper 60s and temps rising toward the upper 80s.
Temperatures warm even further Thursday with afternoon highs in the
low 90s for most and dew points creeping back into the low 70s.

&&

.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas...

Tonight...Mainly VFR this evening as initial showers and storms
dissipate. Next round of showers/storms begin to move in from
the west most likely after 6z with lowering cigs as well. This
should result in sub VFR conditions occuring at all sites by
around 09Z. Winds mainly southeast 5 to 10 knots. Moderate
confidence.

Friday...Sub-VFR in SHRA/TSRA in the morning, then another
round of SHRA/TSRA with sub-VFR conditions possible in the
afternoon. South winds 5 to 10 kt, becoming southwest to
westerly by late day. Moderate confidence in morning
restrictions, low confidence for the afternoon.

Outlook...

Saturday through Sunday night...VFR. W to NW winds 10 to 15 kt
during the day, then LGT/VRB at night. High confidence.

Monday through Tuesday...VFR overall. Scattered afternoon SHRA/TSRA
possible. S winds 5 to 10 kt. Moderate confidence.

Wednesday...VFR. SW winds 5 to 10 kts. Moderate confidence.

&&

.MARINE...
Sub-advisory conditions on the waters through today with winds
around 10 kts easterly becoming southeasterly tonight. Waves
2-4 ft. A round of showers and thunderstorms with gusty winds
and heavy rain possible late tonight and Friday morning, then
again late Friday afternoon and evening.

Outlook...

Friday night through Wednesday...A prolonged period of sub-SCA
conditions anticipated. No chance of showers or storms over the
weekend, with only a slight chance Monday and Tuesday with mostly
dry weather expected Wednesday. Winds will mostly be west to
northwest 10-15 kts over the weekend, becoming southeasterly 10-15
kts Monday and Tuesday then southwesterly on Wednesday. Seas 2-4 ft.

Rip Currents...

Although there will be showers and thunderstorms Friday
morning, and then possibly again Friday afternoon and Friday
evening that could produce locally strong thunderstorms winds,
the overall winds will be out of the south to southeast at 5 to
10 mph. There should be a medium period southeast swell up to 10
seconds. There is a LOW risk for the develop of dangerous rip
currents, outside of thunderstorms, at New Jersey and Delaware
beaches on Friday.

On Saturday, winds turn to the northwest at 5 to 10 mph. A
light easterly swell will be in place. Once again, there will be
a LOW risk for the development of dangerous rip currents at New
Jersey and Delaware beaches.
