Area Forecast Discussion
National Weather Service Mount Holly NJ
110 AM EDT Thu Jul 9 2026

.WHAT HAS CHANGED...
Aviation section updated for 06Z TAFs

&&

.KEY MESSAGES...
1) Humidity returns on Thursday along with potential severe
thunderstorms and flash flooding.

2) Additional rounds of showers and thunderstorms are expected
on Friday which may linger into Saturday before drier conditions
return on Sunday and into early next week.

&&

.DISCUSSION...
KEY MESSAGE 1...Humidity returns on Thursday along with
potential severe thunderstorms and flash flooding.

Weak high pressure over western New York and western
Pennsylvania slides to the south and east this evening and will
be off the Mid- Atlantic coast tonight. Return flow sets up
behind the departing high, and a light southerly flow tonight
will increase during the day Thursday. Dew points in the mid 60s
this evening will increase into the upper 60s tonight, and then
into the mid 70s on Thursday. Although temperatures will "only"
be in the mid 80s or so, which is right around normal for this
time of the year, the heat index will be in the low to mid 90s
due to those high dew points.

The main concern on Thursday will be the potential for showers
and thunderstorms in the afternoon and evening. With low
pressure approaches from the west and tracks towards the Mid-
Atlantic by Thursday evening. A mid-level trough will move into
the Northeast with some shortwave energy passing through the
Delaware Valley, Delmarva, and southern New Jersey.

SBCAPE values will be in excess of 1500 J/kg with PWATS from
2-2.5 inches, highest values from the Delaware Valley, including
Philadelphia, south into Delmarva. 0-6 km shear will be from 25
to 30 kt. The two main threats from severe weather will be
damaging wind gusts and heavy rain leading to localized flash
flooding.

The Storm Prediction Center has a Slight Risk for severe
weather (2 out of 5) for the Delaware Valley south of
Philadelphia, Delmarva, and southern New Jersey, and a Marginal
Risk (1 out of 5) from around Philadelphia north to Allentown.
The Weather Prediction Center has a Slight Risk (2 out of 4) for
Excessive Rainfall for southeast Pennsylvania, southern New
Jersey, the eastern shores of Maryland, and Delaware, and a
Marginal Risk (1 out of 4) for the southern Poconos and northern
New Jersey.

Although some showers and thunderstorms will fire up over far
western portions of the forecast area from noon-2pm, the main
timing will be from 4pm-10pm across the Delaware Valley,
including Philadelphia, the eastern shores of Maryland,
Delaware, and southern New Jersey. While showers and
thunderstorms capable of damaging winds and localized flash
flooding are likely for the northern zones as well, the highest
impacts in terms of potential severe weather and flash flooding
should be focused generally south of Philadelphia.

A warm and muggy night with patchy fog developing Thursday
night after showers and thunderstorms come to an end by
midnight. Lows will be in the upper 60s to low 70s.

KEY MESSAGE 2...Additional rounds of showers and thunderstorms
are expected on Friday which may linger into Saturday before
drier conditions return on Sunday and into early next week.

On Friday, another round of showers and thunderstorms are
expected to develop out ahead of a cold front moving southward
into the area. Similarly to Thursday, moisture is anticipated to
increase ahead of the front, where PWAT values are progged to
be in excess of 1.8 inches. This supports that any given shower
or storm will have the ability to produce heavy rainfall and
flash flooding. As of now, the majority of our forecast area is
highlighted in an MARGINAL risk (Level 1/4) for excessive
rainfall. In terms of the severe weather threat, ML CAPES are
expected to reach at least 1000 J/kg with bulk shear values
around 30 kt. Given better frontal forcing, there looks to be at
least another opportunity for severe weather. As of now, SPC
has our entire area highlighted in just a general thunder risk,
however some of the MLP guidance indicate higher probabilities
especially in terms of damaging winds. It is also worth noting
that Friday will be quite sticky outside with highs in the upper
80s to low 90s with dew points in the low to mid 70s. This will
result in heat indicies in the mid to upper 90s. We may get
close to Heat Advisory criteria in some spots, but basis the
current forecast, heat indicies are expected to remain just
below advisory criteria.

There remains a vast amount of uncertainty with how Saturday
will pan out as guidance continues to struggle with how quickly
the cold front clears the area. Some guidance slows the
progression of the front, keeping more in the way of showers
around on Saturday, whereas others show a faster progression,
yielding mainly dry weather. As mentioned by the previous shift,
opted to stay very close to NBM PoPs for this period, which
keeps 10-30% PoPs north, with 30-60% PoPs mainly across south
Jersey and the Delmarva. Temperatures will mainly be in the 80s.

By Sunday and into early next week, guidance is showing an
expansive upper level ridge setting up over the northern High
Plains. This will yield dry weather and mainly clear skies
across the Mid- Atlantic. Temperatures will be around normal for
Sunday and Monday, but will swing back above normal by Tuesday
and Wednesday.

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Rest of Tonight (through 12z)...Primarily VFR though some MVFR
stratus develops late at all terminals except KACY sometime
between 10z-12z. Winds generally light, though favoring a
south/southwest direction. Moderate confidence.

Today...Primarily VFR though scattered showers and thunderstorms
are expected to develop in the afternoon and early evening.
Coverage of showers/thunderstorms will be focused mainly from
KRDG/KTTN on south. Have added TEMPO TSRA groups at all
terminals except KABE as a period of thunderstorms are
increasingly likely (60-70%) sometime between 18z-00z. Winds
generally out of the south/southwest around 10 kt with higher
gusts anticipated in any thunderstorms. Moderate confidence
overall.

Thursday Night...Primarily VFR as showers and thunderstorms move
offshore. Cannot rule out some patchy fog, especially over areas
that see rainfall. Winds out of the west/southwest around 5 kt
or less. Low confidence.

Outlook...

Friday through Friday night...Mainly VFR with periods of sub-
VFR possible. A chance for showers and thunderstorms in the
afternoon and evening hours.

Saturday though Saturday night...Mainly VFR with a slight
chance of sub-VFR conditions. A chance of showers and
thunderstorms in the afternoon.

Sunday through Monday...VFR. No significant weather expected.

&&

.MARINE...
Sub-Small Craft Advisory conditions tonight through Thursday
night. South to southwest winds around 10 kt, increasing to 10
to 15 kt with gusts up to 20 kt Thursday afternoon, becoming W 5
to 10 kt Thursday night. Seas 2 to 3 feet.

VSBY restrictions in fog possible tonight, then again Thursday
night. Showers and thunderstorms producing heavy rain and gusty
winds will impact the waters late Thursday afternoon and
evening.

Outlook...

Friday through Monday...No marine headlines are expected at
this time. Winds will largely remain between 5-15 kt through
Sunday, with winds up to 20 kt possible on Monday. Seas around
2-4 feet. A chance for showers and thunderstorms are expected
each afternoon and evening through Saturday, with fair weather
returning for Sunday and Monday.

Rip Currents...

For Thursday, winds are more southerly, and the moderate swell
also becomes more southeasterly. This combination gives a
MODERATE risk for the northern NJ beaches, with a LOW risk
further south.

For Friday, winds turn southwesterly, and the swell weakens.
Thus, this should result in a LOW risk of rip currents for all
beaches.
