Area Forecast Discussion
National Weather Service Mount Holly NJ
935 PM EDT Thu Jul 13 2023

.SYNOPSIS...
The chance for showers and thunderstorms returns this evening
as shortwave energy slides through the region. A deep upper low
will build into south-central Canada and several disturbances
will rotate around the low bringing unsettled weather this
weekend and through next week. The upper level low looks to
finally pull away by the middle of next week.

&&

.NEAR TERM /THROUGH FRIDAY NIGHT/...
Unsettled weather on tap with several round of potential
showers and thunderstorms, some of which may be strong to
severe.

A warm and humid airmass is in place with temperatures in the
70s to low 80s. Surface dew points are in the 60s to low 70s,
resulting in 1000 to 2000 J/kg of surface-based CAPE
throughout lingering even at this hour.

Surface trough approaching from the west this evening is
touching off widely scattered showers and thunderstorms, mainly
in the southern Poconos and northwest New Jersey, some of which
will be severe. Most of the thunderstorm activity will be well
north of the southern Poconos, mainly associated with an H5 low
that is tracking through eastern Canada. There is also 25 to 30
kt of 0-6 km Bulk Shear, and PWATs are up around 1.5+ inches.
Gusty winds and heavy rain are possible.

Latest guidance has gone back in the direction of keeping stuff
firing and even increasing in coverage later tonight as another
trough approaches. Boosted POPs late tonight and early Friday
as a result, though kept it chance thunder given the cool part
of the day. With high surface moisture, locally heavy rain will
be possible, and at least at first, some gusty winds as well as
DCAPE may stay elevated until the dry midlevels fully moisten.
Warm and humid overnight with lows in the upper 60s and low 70s.

Due to cloudy skies on Friday, it will not be as warm as it was
today, but it remains humid. Highs will be in the mid and upper
80s with surface dew points well in the low to mid 70s.
Surface- based CAPE values will be up around 2000 J/kg along
with PWATs in excess of 1.7 inches. 0-6 km Bulk Shear will also
be 25 to 30 kt. Another mid-level trough with strong shortwaves
will approach in the afternoon and pass through in the evening,
touching off another round of thunderstorms. The Storm
Prediction Center has most of the area in a Marginal Risk for
severe weather. Heavy rain and strong to potentially damaging
winds possible.

Convection tapers off in the evening from west to east. Fog
possible late as dew points remain in the 70s, though cloud
cover could limit fog development.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
Into Saturday, a strong closed upper low will oscillate around
south- central Canada and introduce an unsettled pattern across
the eastern half of the country. The first half of Saturday
should be mostly dry as subtle height rises continue ahead of an
approaching potent shortwave into the evening and overnight
hours which will again result in shower and thunderstorm
development which may focus along the sea breeze. Continued
southwest flow through most of the column will maintain a
tropical-like airmass; PWAT values will remain high and WPC
again has the region in a Marginal (1/5) risk for excessive
rainfall. Wouldn't rule out a few stronger thunderstorms as the
global guidance favors 1000-1500 J/kg of taller skinny CAPE with
but less favorable shear. Expect that showers will linger into
the overnight hours as continued shortwave energy moves through.
Overnight lows look to remain a few degrees above average in
the low to mid 70s.

Sunday looks to be the more interesting and active day for the
weekend. PWATs will surge into the 2+ inch range, with dewpoints
getting into the mid 70s. An area of low pressure will slide by
to the west, with a cold front slowly approaching the region.
Both severe and hydro hazards remain on the table, but thinking
the main focus will be the potential for flash flooding as storm
motion vectors show signs of slow moving and training
convection. With a long and skinny CAPE profile as well, and
very wet antecedent conditions in most spots, it will not take
much for flooding to occur. Have included mention of heavy rain
in the grids from late Sunday morning into Sunday evening. On
the severe side of things, MLCAPE values look to be around
1000-1500 J/kg with around 30 kt effective bulk shear. WPC
maintains a Marginal Risk for Excessive Rainfall for Sunday.
Temperatures will be in the mid to upper 80s for most spots,
with it feeling downright tropical prior to the onset of showers
and thunderstorms.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
The aforementioned upper low will maintain an unsettled pattern
through early next week. Rounds of shortwaves will rotate
around its base and basically keep diurnally driven
precipitation in the forecast for the duration of the long term
period. A cold front will slide through on Sunday Night, with
the potential for heavy rainfall to continue into the evening.
WPC maintains the Marginal (1/5) risk of excessive rainfall for
the area into Sunday Night. Ensembles indicate a stronger
shortwave moving through the Great Lakes sometime between late
Monday Night and Tuesday, but timing and spatial differences
exist. In terms of temperature and moisture, Sunday Night's
front doesn't look to offer a notable decrease in temperature or
dew point as values will hold around or just above
climatological normals in the mid to upper 80s (some low 90s
possible) for highs and upper 60s/low 70s for lows.

The upper level low looks to finally lift out by the middle of
next week with some of the guidance hinting at a more
progressive pattern overall. Flow looks to turn more zonal but
there still could be some weak shortwaves moving through the
area, bringing continued low-end rain chances for the middle of
the week (around 20-40%).

&&

.AVIATION /02Z FRIDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Rest of tonight (00Z through 12Z)...Generally VFR. There is the
potential for TSRA increasing as the night progresses from NW to
SE, but confidence is low in any one storm passing over a given
terminal. Kept it to VCTS in the TAFs. Light S winds. Low
confidence.

Friday (12Z through 00Z)...Potential for MVFR CIGs. Several
rounds of SHRA/TSRA, first in the morning, again in the
afternoon and evening. Sub-VFR likely. TSRA will result in heavy
rain and gusty winds. S winds 5 to 10 kt. Low confidence.

Friday night (00Z through 12Z)...Any convection tapers off from
west to east. Sub-VFR in fog and stratus. LGT/VRB winds. Low
confidence.

Outlook...

Saturday...Primarily VFR though scattered afternoon showers and
thunderstorms may result in brief restrictions. Southerly winds
around 5-10 kt. Moderate confidence.

Saturday Night...sub-VFR conditions possible with overnight
showers/thunderstorms and patchy fog. South/Southeasterly winds
around 5 kt. Low confidence.

Sunday...sub-VFR conditions likely especially in the afternoon
with widespread showers and scattered thunderstorms.
South/Southwest winds around 10 kt. Moderate confidence.

Sunday Night...sub-VFR conditions likely with rain moving
through into the overnight hours. Southwest winds becoming
northwesterly with the passage of a cold front around 5-10 kt.
Moderate confidence.

Monday through Monday Night...Primarily VFR. Small chance for
showers through Monday Night (15-30%) which could result in
brief restrictions. West/Southwest winds around 5-10 kt.
Moderate confidence.

Tuesday...sub-VFR conditions possible, mainly with afternoon
showers and thunderstorms. Southwest winds around 5-10 kt. Low
confidence.

&&

.MARINE...
Tonight...S winds 15 to 20 kt with occasional gusts to 25 kt.
Do not think the 25 kt gusts will be widespread enough nor
frequent enough to justify a Small Craft Advisory at this time.
Seas will build to 3 to 4 ft, but may be close to 5 ft in some
spots. There is a chance for showers and thunderstorms late
tonight that would reduce VSBYs and result in gusty winds.

Friday...Sub-SCA conditions. S winds 15 to 20 kt. Seas 3 to 4
ft. VSBY restrictions in showers and thunderstorms with heavy
rain and gusty winds.

Friday night...Sub-SCA conditions. S winds 10 to 15 kt. Seas 2
to 4 ft. Lingering showers and thunderstorms, tapering off late.
VSBY restrictions in fog late.

Outlook...

Saturday through Sunday...No marine headlines anticipated.
Southerly winds around 10-15 kt with gusts nearing 20 kt. Seas 3
to 4 feet. Periods of showers and thunderstorms especially on
Sunday afternoon.

Sunday Night...No marine headlines anticipated. West/Northwest
winds around 5-10 kt. Seas 3 to 4 feet.

Monday through Tuesday...No marine headlines anticipated.
Southerly winds around 10-15 kt with gusts up to 20 kt. Seas 3
to 4 feet.

Rip Currents...

For Friday, 10 to 15 kt southerly flow shall be accompanied by
breaking wave heights of 2 to 3 ft for all locations except
Delaware beaches which will see breaking wave heights closer to
1 to 2 ft. Given these conditions along with a medium SSE/S
period swell, there is a MODERATE risk for the development of
dangerous rip currents for the New Jersey and Delaware beaches.

For Saturday, near 10 kt southerly flow shall be accompanied by
breaking wave heights of 2 to 3 ft for all locations except
Delaware beaches which will see breaking wave heights closer to
1 to 2 ft. Given these conditions along with a continued medium
SSE/S period swell, there is a MODERATE risk for the
development of dangerous rip currents for the New Jersey and
Delaware beaches.

&&

.TIDES/COASTAL FLOODING...
Southerly flow has built up the anomalies across Barnegat Bay,
resulting in minor flooding. Issued coastal flood advisory for
Ocean for this reason. Winds likely diminish tomorrow so
uncertain whether it will be needed again.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...None.
NJ...Coastal Flood Advisory until 2 AM EDT Friday for NJZ020-026.
DE...None.
MD...None.
MARINE...None.
