What forecasters said that day

The local office's own words before this heat advisory 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 heat advisory went out at Jul 4, 12:56 AM EDT, 2 hours 38 minutes earlier.

Area forecast discussion, Jul 4, 12:56 AM EDT, 2 hours 38 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1256 AM EDT Thu Jul 4 2024

.SYNOPSIS...
High pressure moves offshore and remains east of the area through
the weekend. Low pressure moves well north of the area Thursday
and sends a few weak fronts towards eastern Pennsylvania and
northern New Jersey. These fronts remain in the area through
Saturday before diminishing. Another system arrives for Tuesday
of next week.

&&

.NEAR TERM /THROUGH TODAY/...
No significant changes from the previous update.

Surface high pressure continues to gradually move off the coast
to our east as a frontal system starts to approach from the
west. However the high will continue to dominate our weather
through the overnight. Cirrus will be increasing from convection
well upstream on Wednesday. Southerly winds generally around 5
to 10 mph and temperatures largely in the mid to upper 60s.

A warm front will be pushing eastward across PA bringing
increasing cloud cover with dewpoints also starting to rise.
There could be a few showers moving into our NE PA zones across
the southern Poconos by very late tonight, but I think that
most likely this will remain to our north and west so POPs
tonight only max out around 15%. Overnight lows will range from
the low to mid 60s across the cooler spots such as the Pine
Barrens and the southern Poconos to the upper 60s around the
urban corridor.

High pressure will continue to move offshore into Independence Day
as a surface low and associated upper level trough move eastward
through eastern Canada. This will push the warm front through the
region early in the day Thursday allowing the area to get into the
warm sector. The warm front could continue to bring a few isolated
showers or storms early Thursday morning, mainly over NE PA into NW
NJ, but with the greater chances for showers and storms arriving
later in the day (mainly after 2 PM). Prior to this, the other story
for the day will be the return of the heat and humidity as highs for
most areas will reach the upper 80s to low 90s (cooler near the
coast and over the Poconos) with dewpoints reaching the upper 60s to
low 70s. This will result in max heat indicies into the 90s for most
areas along and south of I-78. Cloud cover is expected to increase
as the day progresses and winds will be from the south to southwest
near 5-10 mph (15-20 mph near the coasts).

As for the storm threat later in the day, expect storms to fire in
the vicinity of a weakening frontal boundary draped over PA by the
afternoon hours with these storms moving eastward into our eastern
PA and northern NJ zones by later in the afternoon and then
potentially affecting Delmarva and southern and coastal NJ by the
evening. So it won't be an all day type rain event but unfortunately
the timing won't be great as it could interfere with Independence
Day festivities. Our POPs generally max out around 40% to 50% over
much of the area, though are a bit lower near 30% to 40% near the
coast and across Delmarva and a bit higher (around 60 percent)
around Chester and Berks Counties in SE PA. With ML CAPE values
progged to max out around 1000-1500 J/kg along with deep layer shear
values around 30 knots, there is the potential some storms could
become severe. The SPC has a MARGINAL risk (1/5) for severe
thunderstorms extending east into SE PA and Delmarva though it was
pulled back slightly from the previous forecast. Water loaded
downdrafts could lead to a few strong to locally damaging wind
gusts. Given the shear, convection could exhibit some organization,
though widespread severe convection is not expected at this time.
Most guidance has PWats over 2.0" across the entire area, and
largely within the 2.25" to 2.5" range. These values are near record
PWat values for the month of July at IAD and OKX (read: highly
anomalous). WPC keeps most of our area in a MARGINAL risk for
excessive rain but has upgraded SE PA (including Philly) to a SLIGHT
risk as storms will be capable of producing very heavy rain which
could lead to localized flash flooding...especially if storms set up
over the urban areas of Greater Philadelphia.

Storms may linger into a good portion of the evening Thursday before
diminishing overnight. It will be a very warm and muggy night as the
frontal boundary gets hung up over the area. Most areas won't see
lows getting below the low/mid 70s (except 60s over the Poconos).
Some fog development is possible overnight where ever rainfall
occurs.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...
The last day of the week and into the weekend will feature a continuation
of July-like weather with plenty of warmth and humidity. Highs both
days will be above normal with upper 80s/low 90s common across the
region. Dew points in the low/mid 70s for many areas with perhaps
a few upper 70s for Sat around Delaware Bay.

Precipitation chances will be diurnal mostly with slight chance pops
for the morning and higher pops for the afternoon and evening hours.
Sat will have some likely pops for the afternoon as the upper ridge
will have moved away and more subtle shortwaves traverse the region.
Locally heavy rains are possible for the afternoon and evening
hours.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Saturday night,  the showers and tstms across the area Saturday will
gradually end from west to east overnight. We;ll carry chance pops
for the ern areas and slight chc for the NW sections. Some heavy
rains will taper off during the evening. We are not certain how fast
things will end and its possible that some higher pops may eventually
be needed for the evening. Very warm/hot and humid conditions will
continue.

We'll settle into a mid-summer pattern Sunday and into next week
with a stretch of above normal temperatures and varying amounts of
humidity expected. Sunday and Monday will feature more comfortable
dew points (humidity) compared to the last days of the forecast. Dew
points Sun/Mon will mostly be in the 60s before climbing into the
low 70s (with upper 60s NW) for the midweek.

Rainfall for Sunday and Monday will be scarce with an upper ridge
banked across the East Coast. This all changes for Tue/Wed as most
op models depict a slow moving front edging into the area. This could
be the focus for frequent showers/tstms during those periods. We
have capped pops in the chance range at this time since the NBM wanted
likely pops over a wide area. Not comfortable with this attm.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Through 12Z...VFR with no significant weather. Increasing
cirrus. Winds generally southerly around 5 kts. High confidence.

Thursday...VFR in the morning, but with increasing clouds.
Scattered showers and thunderstorms are expected to develop for
the afternoon into the evening hours (mainly after 18z) and
these could bring restrictions if any of these storms move over
a TAF site. The best chances for this look to be around RDG with
lower chances farther south and east toward MIV and ACY. Winds
mainly southwest around 5 to 10 knots except 10 to 15 knots
around ACY. Moderate confidence overall, low confidence exactly
where storms will impact terminals.

Outlook...

Fri./Fri night... Scattered showers/tstms developing Fri
afternoon and continuing overnight lower CIGS/VSBYS at times.

Saturday... VFR early then scattered showers/tstms developing
for the afternoon/evening with lower CIGS/VSBYS possible.

Sat night... Lower CIGS/VSBYS in showers/tstms diminish
overnight. Patchy fog possible at TAF sites that receive any
rain.

Sunday/Monday... Mostly VFR. Patchy fog possible overnight.

&&

.MARINE...
Sub-SCA with fair weather through tonight. Light S or SE winds
increasing to 10-15 kts.

For Thursday into Thursday night, southerly winds increase to around
15 to 20 knots but should stay below Small Craft Advisory levels.
However showers and storms will be possible over the waters by
Thursday evening and these could bring locally stronger winds.

Outlook...

sub-SCA overall with scattered showers and tstms Fri/Sat and
less so Sunday. Low-end SCA gusts and seas possible for the
Ocean Sat afternoon and evening.

Rip Currents...

Independence Day (Thursday)...Southerly winds strengthen with
breaking wave heights increasing. With an onshore component to the
wind for Cape May, Atlantic, and Ocean County, there is a MODERATE
risk for rip currents. With wind direction more shore
parallel/offshore at the Delaware Beaches and northern Jersey Shore,
have elected to go with a LOW risk. Breaking wave of 2 to 3 feet,
though some 4 foot waves are possible within the MODERATE risk
area.

Friday...A New Moon will occur. Winds weaken a bit from Thursday but
become more onshore for much of the NJ shore. There is a MODERATE
risk for rip currents for Cape May, Atlantic, Ocean, Monmouth
County, and a LOW risk for Delaware Beaches. Breaking waves of 2 to
3 feet.

.TIDES/COASTAL FLOODING...
With the New Moon to occur Friday, some locations may see some
spotty minor coastal flooding during the next few high tide cycles.
Any advisory minor coastal flooding is not expected at this time.
