What forecasters said that day

The local office's own words before this special marine 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 special marine warning went out at Jul 17, 11:19 PM EDT, 1 minute earlier.

Area forecast discussion, Jul 17, 11:19 PM EDT, 1 minute before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1119 PM EDT Sat Jul 17 2021

.SYNOPSIS...
An area of low pressure will slowly drift eastward near the
Pennsylvania and New York tonight through Sunday, then across
southern New England through Tuesday. A surface trough will
remain near the area Sunday, before a cold front moves through
and offshore during the day into the evening Sunday. A surface
trough is expected to develop across the east coast Monday into
Tuesday, before another cold front move across the area around
Wednesday. Another cold front is expected toward the end of the
week next week.

&&

.NEAR TERM /THROUGH SUNDAY/...
**Severe Thunderstorm Watch #382 has been allowed to expire**

A cluster of thunderstorms remains across central NJ and DE this
evening, but the trend has been for the storms to slowly weaken
as instability continues to fade this evening. Still though,
severe wind gusts are possible near the NJ coast and central DE.
The severe potential will quickly come to an end over the next
hour or two.

Tonight...Showers will come to an end from W to E overnight and
patchy fog is possible. It will remain humid overnight and lows
will drop into the upper 60s to low 70s for the area. The
surface cold front is also located further west towards central/
western PA and is forecast to slowly move east overnight. The
front will likely not reach our western zones until near sunrise
Sunday morning.

Sunday...The upper trough will still be lingering across NY
state but drier air will have arrived at the mid/lower levels.
Overall, a fair weather day is expected with mostly sunny skies
early then mostly cloudy skies by afternoon. We will continue to
include a chance for a few showers, since some instability will
be present and enough moisture to produce a few showers is
expected. Temperatures Sunday will be closer to normal with
highs mostly in the low/mid 80s for the area. Also, dew points
will be reduced from earlier days, so more comfortable air is
expected.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
For Sunday night through Monday night, a long wave trough will
be in place across the east coast, while the cold front shifts
offshore and an area of low pressure continues to move across
southern New England. A surface trough will likely develop
across the area on the backside of the low and remain across the
area into Monday night. Several short wave/vorticity impulses
will move across the area during this period as well. There will
be a chance for isolated to scattered showers and thunderstorms
during this period.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
The long term period will be unsettled with at least a slight
chance of showers and thunderstorms each day, but two main
periods of higher chances Wednesday and Friday. For Tuesday, a
surface trough will remain in place across the east coast and
combine with a couple of short wave/vorticity impulses, and may
help lead to a chance of isolated to scattered showers and
thunderstorms. However, on Wednesday, a cold front is forecast
to move across the east coast, which should bring an increase
threat for showers and thunderstorms. On Thursday, another
surface trough is expected to develop across the east coast,
which could again lead to a chance of isolated to scattered
showers and thunderstorms. Yet another cold front is forecast to
move across the east coast later in the week around Friday
which will lead to a better chance of scattered showers and
thunderstorms.

Temperatures through the long term period are expected to be
near or slightly above normal.

&&

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

This evening...Scattered showers and thunderstorms will
continue to pop up across the TAF sites, with a line of showers
and thunderstorms moving across the area between 00z-04z. A
period of MVFR to IFR conditions is expected in the heaviest
showers and thunderstorms. Mostly south to southwest winds 10
to 15 knots. Severe tstms are possible with gusts 45-55 knots
possible until 03Z.

Overnight...Showers and thunderstorms taper off by 04z, then
MVFR ceilings are expected to move into the area from the north
as far south as PHL to ILG. IFR ceilings are possible from ABE,
RDG, and TTN late in the night into daybreak Sunday, in addition
to light fog. Light variable winds.

Sunday...MVFR conditions will begin the day, then VFR conditions
will return through the morning Scattered showers are possible
later in the day. Light and variable winds early, becoming west
to northwest 10 to 15 knots with gusts 15-20 knots.

Outlook...

Sunday night-Tuesday night...Mostly VFR. A slight chance of
isolated to scattered showers and thunderstorms which may
temporarily lead to lower conditions. West to northwest winds
5-10 knots, occasional gusts around 15 knots.

Wednesday-Wednesday night...Mostly VFR. A chance of scattered
showers and thunderstorms which may temporarily lead to lower
conditions. West to northwest winds 5-10 knots, occasional
gusts around 15 knots.

Thursday-Thursday night...Mostly VFR. A slight chance of
isolated showers and thunderstorms which may temporarily lead
to lower conditions. West to northwest winds 5-10 knots,
occasional gusts around 15 knots.

&&

.MARINE...
Showers and thunderstorms this evening with severe storms
possible. Overall South winds 15 to 20 knots with some gusts 25
knots possible. We have decided to issue a Small Craft Advisory
through 2 am as winds could continue to increase in the next few
hours. Seas building 3 to 4 ft.

Sunday, sub-SCA expected with SW winds around 10 to 15 knots.
Widely scattered showers possible.

Outlook...

Sunday night-Thursday...Conditions expected to remain below
Small Craft Advisory levels. However, winds could gust around
20 knots at times. There is a chance of isolated to scattered
showers and thunderstorms each day which could lead to locally
higher winds and waves.

Rip Currents...

South to southwest winds 10-20 mph, with occasional higher
gusts will continue across the ocean through Sunday. Seas are
expected to be 3-4 feet as well. This is expected to lead to a
moderate risk of dangerous rip currents.

On Monday, seas subside some to 2-3 feet, while winds diminish
some to 10-15 mph with occasional higher gusts. This is
expected to lead to a low risk of dangerous rip currents.
