Area Forecast Discussion
National Weather Service Mount Holly NJ
116 PM EDT Fri Aug 1 2025

.SYNOPSIS...
A cold front front will push south of the area through today as
low pressure slides offshore. High pressure will then build
from the north into the weekend, with below normal temperatures,
much drier and pleasant conditions expected into early next
week. The high pressure will begin to slide offshore into the
middle to end of next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
No changes to the previous forecast.

Much cooler and somewhat breezy conditions are expected today
along with a chance for some lingering showers and drizzle at
times early.

Broad upper diffluence will remain in place aloft through
today. The cold front will continue pushing southward and away
from our area through today as broad surface low pressure passes
offshore along it. Meanwhile, cooler and much drier Canadian
high pressure will build into the region from the north through
tonight.

This setup will result in cloudy skies much of today along with
an unusually breezy northeast wind by mid summer standards.
Some scattered showers and drizzle will be possible throughout
the day, especially across the coastal plain, though most areas
should remain largely dry overall. Northeast winds 10-20 mph
with gusts up to 30 mph possible, and near 35 mph possible
along the immediate coast. High temperatures will be in the low
to mid 70s, though some cooler spots north of Philly could even
be stuck in the upper 60s all day. We should begin to see the
thick low clouds begin to break up some by mid to late
afternoon with some breaks of sun possible, especially
northwest of I-95 before sunset.

For tonight, much cooler and drier conditions expected with
lessening winds and clearing skies. Low temperatures will range
from the mid 50s up north to the mid 60s closer to the coast and
in the urban corridor. A light north to northeast breeze will
continue.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
A nice weather weekend is finally on tap for the Northeast and
Mid- Atlantic this weekend! High pressure will be over the Great
Lakes on Saturday and then will be over New York and
Pennsylvania on Sunday. Sunny and dry conditions on tap with
temperatures several degrees below normal. Highs on Saturday
will be in the upper 70s to low 80s and then on Sunday will be
in the low to mid 80s. Lows at night will be in the 50s to low
60s. Much needed relief from the heat and humidity of this
summer.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
Dry weather on tap for the first half of the Long Term as high
pressure passes to the north and will be over the Canadian
Maritimes by Tuesday. Thereafter, an H5 trough approaches from
the west and low pressure develops near the Mid-Atlantic. This
may bring some showers, possibly a few thunderstorms, from south
to north to the region Wednesday and Thursday.

Turning warmer next week, and then humidity levels will creep
up as the week progresses with dew points rising into the mid
and upper 60s.

.AVIATION /17Z FRIDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Rest of today...MVFR ceilings linger for the next couple of
hours before clouds begin to lift and scatter out to VFR
beginning west to east. Expecting VFR conditions by sunset for
all terminals. An isolated showers or patchy drizzle may linger
this afternoon, mainly for ACY, but no major impacts to
visibilities are expected. Gusty northeast wind 10-15 kts, with
gusts up to 20 kts will gradually diminish to 10 kts or less by
late afternoon and early evening. High confidence in prevailing
MVFR early this afternoon changing to VFR tonight, but lower
confidence on the exact timing of improvements this afternoon
and evening.

Tonight...Ceilings should be scattered out and lifted to VFR by
around 00Z across the region. North to northeast winds around 5
kts. High confidence.

Outlook...

Saturday through Tuesday...VFR. No significant weather.

&&

.MARINE...
Advisory conditions expected across all coastal waters today.
Winds increasing to 15-25 kts with gusts near 30-35 kts. While
some gale force wind gusts are possible across the Atlantic
coastal waters, duration of these should be brief and confidence
is too low for a Gale Warning. Scattered showers and drizzle
lingering today.

Winds and seas will begin to slowly subside into tonight,
though advisory conditions will remain for the Atlantic coastal
waters. Winds should drop below criteria this evening across
Delaware Bay.

A Small Craft Advisory remains in effect for all coastal waters
beginning through Saturday for the Atlantic waters and for
today for Delaware Bay.

Outlook...

Saturday through Saturday night...Lingering SCA conditions.
Winds diminish to less than 25 kt on Saturday, and then seas
subside to less than 5 feet Saturday night.

Sunday through Tuesday...Sub-SCA conditions.

Rip Currents...

For today, northeast winds strengthen to around 15-30 mph.
Breaking wave heights will vary between 3-5 feet to the north
and 2-4 feet to the south with a building northeasterly 5-7 foot
swell around 7 seconds. Have continued a HIGH risk for
dangerous rip currents for Monmouth and Ocean County beaches
where winds/swell are more perpendicular to shore, with a
MODERATE risk elsewhere where winds/swell are more shore
parallel and seas/surf height will not be great enough to
warrant a high risk. A rip current statement is in effect for
Monmouth and Ocean Counties.

For Saturday, northeast winds 10-20 mph shifting to easterly in
the afternoon. Breaking wave heights 2-5 feet, with a
northeasterly swell of 5-7 feet at around 7 seconds in length.
With the onshore flow and remaining large swells, have placed a
HIGH risk for dangerous rip currents for all beaches. A rip
current statement was issued for all of the Jersey Shore and
Delaware Beaches for Saturday.
