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 29, 2:49 PM EDT, 4 minutes earlier.

Area forecast discussion, Jul 29, 2:49 PM EDT, 4 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
249 PM EDT Thu Jul 29 2021

.SYNOPSIS...
A warm front is forecast to lift into our region today as high
pressure slides out to sea. A cold front will approach from the
Great Lakes today and tonight and it should pass through eastern
Pennsylvania, eastern Maryland, Delaware and New Jersey early
on Friday. High pressure is anticipated to follow for Friday and
Saturday. Another cold front from the northwest is expected to
move toward and through our region on Sunday and Sunday night.
High pressure should briefly influence our weather on Monday
before low pressure passes off the Middle Atlantic coast on
Tuesday or Wednesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
...THERE IS AN ENHANCED RISK FOR SEVERE WEATHER ACROSS THE
REGION TODAY...

A Tornado Watch is in effect for the entire forecast area
through 9 PM tonight.

Most of the region remains in a slight or enhanced risk for
severe weather, as issued by the SPC. The threats are damaging
winds, large hail, and an isolated tornado. The primary threat
time will be this afternoon into evening.

While there are clouds clearly seen on visible satellite across
the area, there are many breaks occurring with peeks of sun
coming through. This is enhancing our instability and as a
result confidence has grown that we will see convection develop
and move through our area this afternoon and evening.

Some early showers and thunderstorms have started to pop up
across Delmarva and New Jersey with the main line of storms off
to the west in central PA. There is still support for effective
bulk shear values of ~45 kts, which will be more than
sufficient to support rotating updrafts. Some upscale growth is
forecast as multiple cold pools start to be deposited and merge.
While areas to the north may see less of the action this
afternoon, there is still the possibility for some strong to
severe storms in those areas. To the south and east, we have
seen much more clearing and temps have risen appreciably in
response. Dew points have climbed into the upper 60s to lower
70s, and heavy down pours remain another threat today though
the storms should have sufficient motion so flash flooding is
not as high on the threat list at this time. However, there is
potential that along the frontal boundary we could see some back
building so we will need to monitor those areas for flooding
concerns.

As the storms clear the coast, surface low pressure will be
located near the NY/Canada border and be dragging a surface cold
front through the area. Winds will slowly turn from the
northwest through the night with skies slowly clearing from the
west.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
A long wave trough will continue to affect the northeastern
states from Friday through Saturday night. A couple of short
waves are forecast to pass over New York and New England on
Friday and Friday night. Any showers associated with short waves
will likely remain to our northeast. Surface high pressure is
anticipated to slide from the Great Lakes on Friday to the
waters off the Middle Atlantic coast on Saturday night, bringing
our region dry weather conditions.

The surface high is expected to be accompanied by unseasonably
low humidity levels in eastern Pennsylvania, New Jersey,
Delaware and eastern Maryland. Dew point readings are forecast
to drop into the 50s by late Friday afternoon and they should
favor the upper 40s and lower 50s on Friday night and Saturday.
They may begin to creep upward into the middle and upper 50s on
Saturday night in the return flow as the high moves off the
coast.

High temperatures should be mainly in the 80s on Friday and
around 80 degrees on Saturday. Readings will likely not get
above the lower and middle 70s in the elevated terrain of the
Poconos and far northern New Jersey on either day. Lows are
anticipated to favor the 50s on Friday night, and the upper 50s
and lower 60s on Saturday night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The long wave trough is expected to remain over the eastern
states from Sunday through Wednesday. A closed low may develop
over Ohio and vicinity on Wednesday. The pattern will prevent
the heat and humidity from building back into our region.
Daytime highs should favor the range from the upper 70s to the
middle 80s with overnight lows mostly from the upper 50s to the
middle 60s.

A mid level short wave and its associated surface cold front
are anticipated to approach from the northwest on Sunday before
making their way across our region on Sunday night. We are
mentioning a chance of showers and thunderstorms mainly from
Sunday afternoon into Sunday evening. The cold front is expected
to nearly stall to our south on Monday as high pressure builds
from the Great Lakes into the northeastern states.

Low pressure developing and traveling along the cold front to
our south should impact our weather in the Tuesday and Wednesday
time frame. The guidance differs on the details, timing and
number of waves of low pressure, so we will simply keep a chance
of precipitation for both days.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Today...MVFR cigs continue to plague the terminals this
afternoon. Winds are generally out of the south to southeast
around 5 to 10 knots and will start to veer to the southwest
through the afternoon. Expect showers and thunderstorms through
the afternoon and early evening with MVFR/IFR conditions at
times between 21-02Z. Winds may gust in excess of 30 knots in
and near thunderstorms. Moderate confidence overall with low
confidence in thunderstorm timing.

Tonight...Becoming VFR after evening showers/thunderstorms and
associated restrictions. MVFR conditions may persist through
about 05Z before clearing. Winds gradually shifting from the
northwest with prevailing speeds 5 to 10 kt. High confidence.

Outlook...

Friday...Mainly VFR. Northwest wind 10 to 15 knots with gusts
of 20 to 25 knots. High confidence.

Saturday...Mainly VFR. Northwest wind 5 to 10 knots, becoming
southwest. High confidence.

Sunday...Some early morning low clouds and visibility
restrictions are possible, otherwise mainly VFR. A chance of
showers and thunderstorms in the afternoon and evening. South to
southwest wind around 10 knots. Medium confidence.

Monday...Mainly VFR. Northwest wind around 10 knots. Medium
confidence.

&&

.MARINE...
This morning... Sub-SCA conditions expected with southeast
winds around 10 kts. Seas 2 to 3 ft.

This afternoon into tonight... Winds will continue strengthen
as the pressure gradient tightens with gusts very close to or at
SCA criteria. Seas building 3 to 4 ft. Given the above, have
issued an SCA for the Atlantic Coastal waters starting at 2 PM
this afternoon and continuing until midnight tonight.
Thunderstorms will cross the waters late this afternoon into
evening. Winds and seas will be higher in and near
thunderstorms.

Outlook...

Friday through Monday...No marine headlines are anticipated.

Rip currents...

Winds will increase to 15 to 20 kts today with gusts at SCA
criteria. There will be an onshore component for the NJ coast
today as winds veer from the south. Given the above, and the 8
second period forecast, the rip risk for Coastal Cape May and
Coastal Atlantic will be MODERATE today. The rest of the beaches
will be kept at LOW given the orientation of the coastline
relative to the wind direction. Winds shift offshore for Friday,
so the rip risk for Friday will be LOW.
