Area Forecast Discussion
National Weather Service Mount Holly NJ
316 AM EDT Wed Jun 17 2026

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

&&

.KEY MESSAGES...
1. Scattered showers and thunderstorms associated with a warm
front will be possible today.

2. Severe thunderstorms possible Thursday afternoon and evening
along with breezy and hot conditions.

3. Tide levels will remain elevated through Wednesday night's
high tide cycle which may lead to areas of spotty minor to minor
tidal flooding.

&&

.DISCUSSION...
KEY MESSAGE 1...Scattered showers and thunderstorms associated
with a warm front will be possible today.

A stationary front over the Mid-Atlantic will lift north as a
warm front as low pressure over the Great Lakes tracks east.
Some showers, and perhaps a thunderstorm, will develop over
Delmarva during the early morning hours. As that front lifts
north throughout the day, it will interact with some midlevel
shortwave energy in the afternoon that will result in another
round of showers and possible thunderstorms, mainly across the
southern Poconos, Lehigh Valley, and northern New Jersey this
afternoon. A few of the stronger storms may be capable of
damaging wind gusts.

Today will be warmer with highs in the low to mid 80s and
surface dew points will creep up into the upper 50s to low 60s.

KEY MESSAGE 2...Severe thunderstorms possible Thursday
afternoon and evening along with breezy and hot conditions.

A closed upper-low over portions of Manitoba and Ontario will
continue to meander in that region, with large scale troughing
in place over much of the Northern CONUS. On Thursday, a strong
shortwave still appears poised to round the base of the trough,
ejecting through southern portions of Ontario and Quebec
southward into New England, taking on an increasingly negative
tilt as it does so. A belt of enhanced flow aloft will
overspread the region as the shortwave passes to the north. At
the surface, a warm front looks to lift through the area during
the early morning hours. Low pressure looks to track north of
the region with a tailing cold front passing through the region
during the afternoon and into the evening hours.

Showers and perhaps a few elevated thunderstorms appear likely
during the morning hours across primarily east central PA and
northern NJ. Severe weather appears unlikely with this initial
round of activity. Southeastern PA, central and southern NJ, and
the Delmarva will likely remain dry through the morning and
into the afternoon.

As the shortwave and cold front begin to approach the region
Thursday, unseasonably strong mid and upper-level flow will
overspread the region. Guidance suggests H5 flow on the order of
60 kt or greater. This will lead to deep layer shear on the
order of 50- 55 kt. Ahead of the cold front, temperatures appear
likely to surge into the upper 80s to lower 90s with strong
southwesterly low-level flow. In addition, moisture will
continue surging into the area, with dewpoints rising into the
upper 60s to near lower 70s, though at least modest mixing does
appear probable with the strong surface heating. The result will
be at least some destabilization, with guidance generally
depicting MLCAPE values around 1000 J/kg.

Latest guidance has trended a little faster with the shortwave,
with both the GFS and NAM showing it passing north of the area
mid- morning into early afternoon. The ECM continues to feature
a slightly slower northeastward progression of the wave, with it
passing north of the region during the afternoon. This will be
an important detail to monitor over the next couple of days as
it will play a role in storm coverage along and ahead of the
cold front. If the wave does indeed pass through earlier in the
day, despite the flow remaining enhanced aloft, subsidence in
the wake of the wave could make storm development a little more
difficult. Nevertheless, the strong cold front should still be
able to serve as a focus for isolated to scattered storm
development. Given the destabilization and impressive
kinematics, any storms that do develop will have the potential
to be severe. The primary threats appear to be damaging winds
and perhaps some instances of hail given the strong yet
unidirectional shear.

Outside of the severe thunderstorm potential, it will also be a
hot and very breezy day. With temperatures in the upper 80s to
lower 90s and dewpoints in the upper 60s to lower 70s, heat
indices in the low to mid 90s are likely for the I-95 corridor
and points south and east, with drier and slightly cooler
conditions to the northwest. The surface low that is expected to
track north of the area will be fairly deep, likely around 990
mb or perhaps a bit deeper. This will lead to a strong mass
response with intensifying southwesterly flow into the
afternoon. As of right now, it appears wind gusts of 25-35 mph
will be common areawide. It still appears unlikely that Wind
Advisory criteria will be met, but it will be noticeably breezy.

KEY MESSAGE 3...Tide levels will remain elevated through the
high tide cycle tonight which may lead to areas of spotty minor
to minor tidal flooding.

After the New Moon on Sunday, the elevated astronomical tides
will continue to subside. However, spotty minor to minor areas
of coastal flooding may continue to affect portions of the
southern New Jersey Atlantic Coast and along Delaware Bay
through the high tide cycle tonight.

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

Early this morning...VFR. A few SHRA may result in brief VSBY
restrictions. LGT/VRB winds. Moderate confidence.

Today...Overall, VFR, but VSBY restrictions possible in
scattered afternoon SHRA, even a TSRA, mainly at KRDG/KABE/KTTN.
S winds 5 to 10 kt, increasing to around 10 kt with a few gusts
to 20 kt this afternoon. Moderate confidence.

Tonight...VFR. SE winds 5 to 10 kt. Moderate confidence.

Outlook...

Thursday...Prevailing VFR, but period of restrictions is
probable in the afternoon and evening as showers and some
thunderstorms increase in coverage. Southwest winds gusting
25-35 kts outside of any thunderstorms.

Friday...A few showers and thunderstorms may linger with some
restrictions possible at times, but VFR should generally
prevail.

Saturday...VFR. No significant weather.

&&

.MARINE...
Sub-Small Craft Advisory conditions today and tonight. Southeast
winds 5 to 10 kt become south 10 to 15 kt with gusts up to 20
kt later today and tonight. Seas will average 2 to 3 feet.

Scattered showers and thunderstorms may impact the waters later
this afternoon.

Outlook...

A Small Craft Advisory is now in effect for Thursday and
Thursday evening. South winds increase to 15 to 25 kt with gusts
up to 30 kt. Brief southerly wind gusts could be close to gale
force within 5 miles of the coast on Thursday. Showers and
thunderstorms will again be possible in the late in the
afternoon and evening bringing a lightning threat and hazardous
seas with significant wave heights building 4-7 feet through the
overnight hours.

Heading towards the weekend, winds and seas drop below SCA with
no marine hazards anticipated.

Rip Currents...

Today, southeast winds will increase to 10 to 15 mph with gusts
up to 20 mph. Breaking waves will be 1 to 2 feet with a light
southeast swell with a 6 to 8 second period. This will result in
a MODERATE risk for the development of dangerous and life
threatening rip currents for the Jersey Shore and a LOW risk at
Delaware Beaches.

On Thursday, south-southwest winds will be increasing to around
15 to 20 mph with gusts as high as 25 to 35 mph in the
afternoon. A southeasterly 4 to 6 foot swell at 6 to 7 seconds,
will lead to breaking wave heights of 2 to 4 feet. As a result,
have opted to go with a HIGH risk for the Jersey Shore and a
MODERATE risk for the Delaware Beaches of dangerous rip
currents. No rip current statement has been issued at this time,
but will likely be needed with upcoming forecast cycles.
