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 Aug 23, 3:12 PM EDT, 2 hours 27 minutes earlier.

Area forecast discussion, Aug 23, 3:12 PM EDT, 2 hours 27 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
312 PM EDT Mon Aug 23 2021

.SYNOPSIS...
The remnants of Henri will move from southern New England to the
adjacent offshore Atlantic waters through Tuesday. High pressure
will build into the eastern U.S. Tuesday, remaining in place
through much of the week. A cold front is forecast to move into
the Mid-Atlantic late this week into the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
As the decaying Henri begins its shift eastward across southern
New England in tandem with a fairly potent midlevel vorticity
maximum, the cooler/drier air aloft is prompting instability
showers and storms to develop generally north of the
I-76/Atlantic City Expressway corridors this afternoon. With
MLCAPE 1000-1500 J/kg and PWs approaching 2 inches, the most
intense convective cores were capable of producing torrential
downpours and some decent outflow winds. Fortunately, the storms
are quickly moving, so not expecting much of an additional
flood threat, though some quick ponding and nuisance urban
flooding is likely. The convection is diurnally driven and will
quickly diminish with the loss of daytime heating early this
evening.

Dry conditions should prevail from the overnight hours through
Tuesday, as midlevel ridging will build in the wake of Henri.
Though some minor drying of the low levels is expected tonight
and Tuesday, backward trajectories are rather weak and will
gradually transition back to the south. As a result, warm and
rather humid conditions are expected even on Tuesday, though
forecast heat indices should remain well below advisory criteria
(likely low 90s north to the mid/upper 90s near/southeast of
the urban corridor).

Only other concern of note is the potential for patchy fog
tonight, though the subtle west to northwest winds at the
surface and associated lowering of dew points by a few degrees
may preclude more widespread development. For now, think the
potential is low enough to keep out of the forecast, but will
monitor trends closely this evening to see if eventual inclusion
is required.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
Temperatures will remain warm Tuesday night with most areas staying
in the lower 70s. During the day Wednesday, weak mid-level ridging
will depart to the east with a weak shortwave approaching from the
west. PWATs Wednesday morning will be around 0.8" and the forcing
for ascent with the wave is poor at best. Given this, have kept the
forecast dry for Wednesday. The lower PWAT air will also allow
temperatures to rise solidly into the lower 90s (with mid 90s
possible in some areas). This also means that apparent temperature
values will be close to heat advisory criteria.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
The long range forecast still on track with cooler air
overspreading the region over the weekend.

On Thursday, a weak lee side trough will remain across the
region with PWATs recovering to around 1.8". Given this, it
looks like the chance of precipitation returns to the region on
Thursday, but doesn't appear to be overly high though given the
lack of any strong synoptic scale forcing for ascent. High
temperatures Thursday will again be in the low 90s with apparent
temperatures near heat advisory criteria.

By Friday, the upper level low that was over the Hudson Bay will
begin to amplify and dive southeast over Quebec. An
accompanying cold front will sweep southeast across New England and
stall somewhere over New Jersey. Convection will likely be
associated with the cold front, the key is just how far south the
cold front makes it.

Saturday into Sunday surface high pressure over New England will
drift southeast towards the Gulf of Maine. Temperatures will
be near normal for this time of year, with a chance of precipitation
continuing through the weekend especially near the stalled front.

On Monday, the stalled front will lift northward ahead of a
shortwave moving across southern Ontario and Quebec. Temperatures
will be warmer with a good chance for afternoon and evening
convection.

&&

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

This afternoon...Mainly VFR with scattered showers and isolated
storms. There may be brief restrictions at the terminals if/when
any heavier downpours develop and move through; however, their
expected short duration and low confidence regarding timing
precludes introduction into the TAFs. Winds generally west
around 10 kt with occasional gusts to 20 kt. Moderate confidence
on prevailing conditions; low confidence on precipitation.

Tonight...Mainly VFR with showers dissipating rapidly after 00z.
Patchy fog may develop late tonight, though confidence on
coverage/duration is low. Have included mention at ABE/TTN/MIV
for now. Winds becoming light and variable. Moderate confidence.

Tuesday...VFR with west to northwest winds up to 10 kt. High
confidence.

Outlook...

Tuesday night...Generally VFR conditions. Light and variable
winds. High confidence.

Wednesday- Wednesday night...Generally VFR conditions.
Localized patchy fog at night. Winds will vary between south to
southwest 5-10 knots during the day, then become light and
variable overnight. Moderate confidence.

Thursday- Thursday night...Generally VFR conditions. A chance
of showers and thunderstorms which could temporarily lead to
restrictions in visibilities. Localized patchy fog at night.
Winds will vary between south to southwest 5-10 knots during the
day, then become light and variable overnight. Moderate
confidence.

Friday- Friday night...Generally VFR conditions. A cold front
will approach the terminals from the north. Showers and
thunderstorms will be possible along and ahead of the cold
front. Southwest winds 5-10 knots during the day, then veering
from the north overnight. Low confidence on frontal timing.

Saturday...VFR conditions, but MVFR in any thunderstorms. Northeast
wind 5 to 10 knots. Moderate confidence.

&&

.MARINE...
Sub-advisory winds and seas are expected through Tuesday. West
winds generally 5 to 15 kt through tonight will become southerly
on Tuesday, possibly gusting to around 20 kt or so. Seas will
generally be 2 to 4 feet.

A few showers/storms may occur through early this evening,
mainly on the waters adjacent to New Jersey, with gusty winds
and locally higher waves in their proximity.

Outlook...

Tuesday night-Saturday...Conditions are expected to remain
below Small Craft Advisory levels through the period.

Rip Currents...

The rip-current risk through this evening is in the MODERATE
category. The risk for Tuesday looks to be MODERATE for NJ and
LOW for DE, as offshore flow continues and surf heights
remaining somewhat elevated.
