Area Forecast Discussion
National Weather Service Mount Holly NJ
640 PM EDT Fri Aug 8 2025

.SYNOPSIS...
High pressure initially centered over portions of the Mid-
Atlantic and New England will shift slowly eastward through the
weekend and into the early part of next week. Tranquil weather
conditions are expected. By mid-week, the high should weaken and
shift farther offshore, allowing for a slightly more unsettled
pattern to take shape.

&&

.NEAR TERM /THROUGH SATURDAY/...
Even as high pressure slowly slides eastward, it will continue
to be the dominating influence on our weather conditions through
the near term forecast period.

Any lingering diurnal cumulus will dissipate after sunset
resulting in mostly clear skies overnight. Winds will decrease
and back slightly to the north-northeast as a result of the
shifting high. Lows will fall mainly into the mid 50s to low 60s
thanks to the ideal radiational cooling conditions.

Heading into Saturday, more tranquil conditions are expected
across the area. Inland areas will see mostly clear skies with
winds around 5-10 mph and high temperatures mainly in the low
80s. Along the coasts of New Jersey and Delaware, some cloud
coverage may redevelop as a result of the continuing onshore
east- northeasterly flow. Winds along the coast may also be a
bit stronger with a few gusts of 15-20 mph possible. Temps will
be a few degrees cooler here as well, mainly in the upper 70s.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
With lightening winds and mostly clear skies Saturday night,
temperatures will quickly clear during the overnight hours, with
lows generally in the mid 50s to near 60.

On Sunday and Monday, with the high pressure centered more on
our area, lighter winds and a bit of a warm up are anticipated.
Under plentiful sunshine, highs are expected to generally be in
the low-mid 80s, though the urban corridor will see
temperatures in the upper 80s to around 90. Without significant
moistening, it should still be a fairly pleasant day overall.
Lows Sunday night and Monday night should also be a little bit
warmer, in the low-mid 60s for most areas.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Significant ridging aloft will begin to break down some Tuesday
through Friday. At the surface, high pressure originally
centered over the area will gradually broaden and weaken,
potentially allowing for a slightly more unsettled pattern to
take shape towards the end of the extended period.

Temperatures will be on a continued warming trend through the
period, with highs ranging from the mid 80s to near 90 on Tuesday,
and potentially climbing to between 90 and 95 by Wednesday and
Thursday, before backing off to the 80s on Friday. Overnight
lows will be steadily warming as well, potentially into the low-
mid 70s by Wednesday night and Thursday night. Moisture will be
on the increase also, with dewpoints in the 70 to 75 range by
mid- week.

While the pattern does not look to be favorable for widespread
thunderstorms, there will be widely scattered afternoon and
evening convection across parts of the area Wednesday into
Friday.

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

Tonight...Prevailing VFR with decreasing clouds. Winds expected
to decrease and could go light and variable for a period,
though the prevailing direction should be northerly or north
northeasterly. High confidence.

Saturday...VFR conditions with mainly clear skies except at KACY
where FEW-SCT clouds are possible. East-northeasterly winds
around 5-10 knots with a few gusts up to around 15 knots
possible at KACY. High confidence.

Outlook...

Sunday through Wednesday...No significant weather expected.

&&

.MARINE...
The Small Craft Advisory from Little Egg Inlet to Fenwick
Island has been extended through 8 AM Saturday. No marine
headlines are in effect elsewhere.

Seas will be continuing to lower through the period but look to
remain around 5 feet near and south of Little Egg Inlet through
the overnight hours, resulting in the extension of the current
SCA. Otherwise, east-northeast winds around 10-15 kt are
expected to continue through Saturday with occasional gusts up
to 20 kt possible south of Little Egg Inlet. Fair weather.

Outlook...

Sunday through Wednesday...No marine headlines are anticipated,
with winds remaining below 25 kts and seas remaining below 5
ft.

Rip Currents...

For Saturday, the onshore flow continues despite winds and
waves coming down slightly compared to Friday. However, given
that we also have the full moon tomorrow, a HIGH risk for the
development of dangerous and life threatening rip currents is
likely. A Rip Current Statement has been issued for all of the
Jersey Shore and Delaware Beaches.

For Sunday, the onshore flow continues with wave heights up to 3
feet. The period is around 7-8 and we are still close to the
full moon which happens Saturday. Right now, the risk for the
development of dangerous and life threatening rip currents has
been put as MODERATE but a potential for a HIGH risk day is
possible with a future update.
