Area Forecast Discussion
National Weather Service Mount Holly NJ
418 AM EDT Sun Jul 16 2023

.SYNOPSIS...
A large low pressure system over Canada will send a few waves
of low pressure across our region into early next week. Among
those, a weak cold front is expected to cross our region Sunday
into Sunday evening, with widespread precipitation expected
ahead of the front. Broad, weak high pressure will build in mid
week, before a trough approaches our region at the end of next
week.

&&

.NEAR TERM /THROUGH MONDAY/...
After a brief lull around midnight, in between a seemingly
never- ending stream of shortwaves passing by our region, a more
potent wave is quickly approaching with showers and embedded
thunderstorms with heavy downpours expanding across much of our
region early this morning. This is accompanied by stronger and
larger scale forcing, as well as a slug of deep sub- tropical
moisture. HREF probability- matched mean 6-hour QPF have many
areas near and west of I-95 seeing 1 to 1.5 inches of rain
through 8 AM, with locally near 3 inches possible where any
storms persist. Areas near and north of I-78 and particularly
I-80 may be most at risk, not just due to where the heavy rain
is projected, but because these areas have recently seen heavy
rainfall, with saturated soils making the region primed for
flooding.

Continuing during the day on Sunday, model guidance suggests the
most persistent thunderstorm activity will shift eastward across
Delaware and New Jersey, with similar HREF PMM amounts as was
mentioned above. The main axis of heaviest rain may shift
eastward toward the coast even by this afternoon, however
additional scattered showers and thunderstorms will likely
develop even back to the west across eastern PA as a cold front
approaches. Those may be more scattered in nature with perhaps
less potential for training compared to what we expect to the
east of I-95 today, but given eastern PA into northwest NJ has
been particularly hard hit the last few days with very saturated
soil conditions, it will not take much more rain to cause
flooding issues. We will continue the Flood Watch everywhere
through midnight. Activity will likely diminish with the loss of
daytime heating and a cold front pushing through early this
evening, with possible just isolated showers and thunderstorms
after 6 PM dissipating completely after 9 PM or so.

Aside from the flooding threat, isolated severe thunderstorms
will be possible through this afternoon, especially if we see
any partial sunshine and breaks from this mornings more
persistent downpours. CAPE and DCAPE look more minimal compared
to the last couple of days, but there will be enough shear so
that if any storms are able to become more discrete, some
stronger updrafts may develop. The main threat will be locally
gusty winds. SPC has a 5% tornado area and a slight risk near
northeast NJ, mainly just out of our area. Thinking the threat
is very low in most of our region with not too much in the way
of low-level veering winds.

Today will be a very humid, muggy day otherwise, with dewpoints
into the mid-70s, even upper-70s in some spots, along with highs
well into the 80s. Even this morning low temperatures have
struggled to drop below 80 in some spots. Tonight into Monday we
will see a 'break' in the humidity, with dewpoints dropping back
into the 60s, but the increased mixing and still warm airmass
with westerly flow will actually support temperatures rising
into the low 90s Monday afternoon. It will be a dry day with a
fair amount of sunshine. Some areas of fog may develop tonight
though, and that may last into early morning Monday.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/...
The next in the series of short wave troughs associated with the
larger mid and upper level low over the Hudson Bay region will
approach our region on Tuesday. Consequently, have a significant
chance for showers and storms across the region especially
during the day on Tuesday as mid an upper level forcing may be
coincident with peak day time heating. PWATs will again get
near 2 inches as steady south/southwesterly flow sets up, with
dewpoints expected to get into the 70s yet again.

At the surface, another weak cold front is expected to approach
and cross through the region on Tuesday night. It is uncertain
how much of an impact this will have on the evolution of showers
and storms across the region as it will be getting weaker as it
approaches the region and may not arrive until late Tuesday
night.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Updated the long term portion of the forecast early tonight as
to focus on the storm threat after midnight. The main concern
through this period is the timing of any short wave troughs
associated with the larger Hudson Bay low which could dig south
far enough to bring precipitation chances to our region. At this
point, the favored period is Thursday into Friday. Not only
is guidance continuing to depict a mid level short wave trough,
but a stronger cold front is possible on Friday. Otherwise, a
series of weak high pressures will largely be in place for the
middle part of the week. However, the subsidence associated with
these high pressures likely won't be quite strong enough to
completely suppress diurnal shower activity. Therefore, PoPs
remain in the 20 to 40 percent range for much of the area
throughout the long term.

Temperature wise, We should be near or slightly above normal
through much of the week, but there is increasing confidence
that the cold front depicted on Friday will bring a
significantly cooler air mass than we have seen lately. If this
trend continues, then temperatures slightly below normal are
possible by the end of the week.

&&

.AVIATION /07Z SUNDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas...

Today...Numerous showers and thunderstorms expanding across our
region, with periods of heavy rain and IFR to even briefly LIFR
VSBY possible particularly around the I-95 corridor this
morning. That will tend to shift east across NJ this afternoon,
but scattered thunderstorms will still be possible back to the
west until activity diminishes and shifts offshore this evening.
Ceilings are generally around 010-020, with localized. Some
periods of improvement to VFR will be possible after 15Z or so,
at least outside of shower and thunderstorm activity, but
widespread and sustained improvement to VFR should not be
expected until this evening. Low confidence in the details of
timing thunderstorms and IFR/LIFR conditions.

Tonight...Showers and thunderstorms dissipating or shifting
offshore around 22-02Z, with VFR conditions likely at least
initially. However, areas of fog may develop, especially outside
of the urban corridor, but would not rule out some there as well
particularly toward 12Z. Very light westerly winds. Low
confidence in fog formation.

Monday...VFR. W to SW winds 4 to 8 kt. High confidence.

Outlook...

Tuesday...VFR in the morning, with sub-VFR conditions possible
in the afternoon with showers and thunderstorms developing.
Southerly winds around 10 kt. Moderate confidence.

Wednesday...Mainly VFR. A few evening showers and thunderstorms
possible. Winds 5 to 10 kts. Moderate confidence.

Thursday...Mainly VFR. Restrictions possible with scattered
afternoon and evening showers and thunderstorms. Southwest winds
around 5 to 10 kts. Moderate confidence.

&&

.MARINE...
While winds and waves will remain below Small Craft Advisory
levels through Monday, scattered tstms will have localized
higher seas and winds this morning through the early evening
hours. We have already issued a special marine warning for
Delaware Bay overnight, and more of those may be needed.
Southerly winds may briefly be above 15 kt this morning
particularly north of Barnegat light. Winds will ease and turn
westerly behind a cold front tonight. Seas mostly 3 to 4 ft for
the ocean and around 2 to 3 ft for Delaware Bay.

On Monday, light NW winds early will become S around 10 kt or so
in the afternoon. Seas remaining around 3 to 4 ft.

Outlook...

Tuesday through Thursday...Winds and seas should stay below SCA
criteria.

Rip Currents...

A southerly wind 10 to 15 MPH is anticipated for Sunday with
breaking waves around 2 to 3 feet and a medium period east to
southeast swell. The expected conditions will likely result in a
MODERATE risk of dangerous rip currents along the coasts of
Delaware and New Jersey at that time.

A northwest to west wind 5 to 10 MPH on Monday morning is
forecast to become southerly in the afternoon. Breaking waves
should be 2 to 3 feet with a medium period east to southeast
swell. However, the guidance also indicates the arrival of an
underlying long period swell from the east and southeast which
could enhance the rip current risk. As a result, we will again
carry a MODERATE risk for Monday.

&&

.HYDROLOGY...
A Flood Watch is in effect for all of our PA and NJ counties,
with New Castle County, DE included as well. A widespread 1 to 2
inches of rain is expected for most of the region, with some
locations in northern NJ and eastern PA expected to see 2 to 2.5
inches of rain. Locally higher amounts between 3 to 5 inches
are possible. Taking into account antecedent conditions, it will
not take much for flash flooding to occur, especially in
northern NJ and eastern PA. There remains potential for main-
steam river flooding to occur due to excessive runoff,
particularly later today and tonight. Some rivers, primarily in
northern NJ, are already running high.
