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 14, 7:52 PM EDT, 5 hours 55 minutes earlier.

Area forecast discussion, Aug 14, 7:52 PM EDT, 5 hours 55 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
752 PM EDT Sat Aug 14 2021

.SYNOPSIS...
A front will continue to cross the region this evening and settle
south of the area into early next week. High pressure will cross
north of the area Sunday and Sunday night before moving offshore.
Unsettled conditions will return to the area early next week as a
warm front and upper air disturbances arrive from the Ohio Valley.

&&

.NEAR TERM /THROUGH SUNDAY/...

As of 7:30 this evening the cold front has made it roughly to
the I-95 corridor based the surface dewpoints and satellite-
derived PWAT fields (the wind shift as mentioned in the previous
discussion occurred well ahead of the boundary). This boundary
has not been very productive from a convective standpoint with
only some cu and short-lived showers forming on it thus far this
afternoon... potentially a result of the upper-support pushing
off to the north while the best instability remains to our
southwest. Given these trends trimmed backed PoPs through early
this evening, but did retain mostly low-end Chc PoPs near the
NJ coast/over Delmarva where there is a bit more instability for
the boundary to work with.

The front will continue its southward push through the evening
hours and should reach the far southern portions of our area
around 06Z. There are indications that a convectively-enhanced
mid-lvl perturbation may induce some minor low-lvl wave
development along the boundary late tonight into early Sunday
morning bringing a renewed chance of showers (maybe an isolated
rumble of thunder as well) to primarily Delmarva and far
southern NJ. Raised PoPs a bit in the 04-10Z period to cover
this potential, but suspect that outside of some locally heavy
rainfall, impacts should be fairly limited.

By sunrise Sunday morning, dew points will be in the 50s for
much of the region! The dewpoints will likely be the more
significant change with this front as compared to the
temperatures. Lows tonight should be mostly in the 60s (upper
50s possible in the mountains, near 70 possible along the
coast), with highs tomorrow mostly in the 80s (70s possible in
the mountains and along the coast). While that will be a nice
change from lows in the 70s and highs in the 90s, it is
generally a 5 to 10 degree decrease as compared to recent
temperature trends, while dewpoints will be almost 20 degrees
lower than what we have seen the last several days.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
After drier and more comfortable air being across the region during
the near term, a return to more typical August weather will happen
during the short term. The high pressure to the north will move offshore
Monday and a return flow off the ocean will commence. Upper heights
will build as well, so while higher dew points will be back, chances
for rain will be low at first, and probably be restricted to Delmarva
and srn NJ. Highs both Monday and Tuesday will be close to normal
with low/mid 80s for the Delmarva, metro Philly and srn NJ. Across
the srn Poconos and north NJ highs will be mostly in the mid/upper
70s.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Temperatures will climb back to a little above normal for the middle
and later parts of the upcoming week. It doesn't appear that any
excessive heat is in our future however. An upper ridge will continue
to build across the Southeast states. Considering the tropics are
becoming more active, a building ridge to our south may keep any
menacing disturbances from moving towards the Middle Atlantic. Either
way, several weak disturbances will ride up across our area to the
west of the ridge and bring almost daily chances for showers and
a few tstms Wed-Fri and probably into next weekend as well. Thursday
will feature the greatest chances for showers as an approaching shortwave
and front may drop down from the Great Lakes at that time. We have
mostly higher end chance and low likely pops for the area. Highs
will run mostly mid/upper 80s with lows favoring the mid/upper 60s
N/W and low 70s S/E.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Tonight... Mostly VFR conditions are expected, although some
4-5k ft ceilings will be possible, particularly at KPNE
and southward. Some showers will be possible at KILG, KMIV, and
KACY but restrictions are not anticipated. Winds varying
between Northerly/Northeasterly around 5kts. Moderate
confidence.

Sunday...VFR conditions expected with winds initially out of
the NE around 10kts, then veering to more E-SE at most of the
eastern terminals in the afternoon, while winds may take on more
of a W-NW component at the western terminals.

Outlook...

Sun night...VFR expected.

Mon/Mon night...VFR. A few isolated/scattered showers/tstms
expected Mon evening and night. Patchy fog possible Mon night.

Tue thru Thu...VFR much of the time. Scattered showers and tstms
with lower CIGS/VSBYS at times during mostly the afternoon and
evening hours. Patchy morning fog also possible.

&&

.MARINE...
Winds and seas should stay below SCA criteria through Sunday.
However, winds are expected to shift to northwesterly by late this
afternoon, and northeasterly by Sunday morning. Winds will likely
gust above 20 kt Sunday morning, but still expect gusts to stay
below 25 kt.

Outlook...

Overall, sub-SCA with fair weather much of the time. Scattered tstms
Tue-Thu with localized higher winds and seas possible.

Rip Currents...

Although a light onshore flow will develop by Sunday and persist
through Monday, this flow will remain light (10-15kts), and
seas (a mixture of NE-wind waves and low amplitude SE-S swell)
should remain 2-3 ft. Consequently we are currently forecasting
a LOW risk of rip currents for both days.
