Area forecast discussion, Sep 15, 4:13 PM EDT, 2 hours 16 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
413 PM EDT Wed Sep 15 2021

.SYNOPSIS...
A cold front will drop down into the region this evening, then
stalls nearby Thursday before washing out on Friday. A coastal low
may bring some unsettled weather to the region Friday before moving
away on Saturday. High pressure will build in on Sunday, eventually
settling over the waters off of New England through mid week.

&&

.NEAR TERM /THROUGH THURSDAY/...
A fast moving mid-level trough will pass north of the area tonight
providing forcing for showers and thunderstorms through much of the
period in the vicinity of a slow moving frontal boundary, which will
move into the area overnight. The remainder of the daytime is
expected to be mostly rain-free, although storms developing and
intensifying across central PA will continue moving eastward into
the evening hours. The wind should favor the south with speeds
increasing to 10 to 15 MPH and gusts reaching 20 to 25 MPH.

With the environment ahead of the precipitation being fairly
unstable, the thunderstorms are expected to become strong to severe.
Mixed layer CAPE values are forecast to peak in the 2000 to 2500
J/kg range along with deep layer effective shear in the 30-35 kt
range. A new Severe Thunderstorm Watch has been issued until 10 PM
for portions of northwest NJ and also includes the portions of
eastern PA covered by the initial watch, effectively replacing the
first one. This is to highlight the threat of damaging winds with
any stronger storms that move into the area late this afternoon and
through evening.

Based on the somewhat late arrival time of the thunderstorms, they
should begin to slowly weaken during the evening hours as they move
toward and into the Interstate 95 Corridor. All the guidance
suggests this trend, but there are differences in how quickly the
decrease in convective activity will take place. We will forecast a
very gradual weakening between 8:00 PM and midnight, with only some
lingering showers after that time. The Severe Thunderstorm Watch may
need to be extended in time or expanded slightly in area in a future
update based on the latest trends, but this seems unlikely at this
time. The CAMs have been consistent in indicating another round of
showers and thunderstorms developing across Delmarva and moving
across the coastal plain and Philly metro overnight. I have adjust
the PoP forecast up slightly for this period in these areas.

As deep moist return flow continues, precipitable water values will
rise into the 1.6-1.9" range, resulting in a heavy rainfall threat.
The potential for locally heavy rain also seems confined mainly to
the Poconos, Berks County, the Lehigh Valley, and northwestern New
Jersey where the stronger convection is most likely to be located.
The threat does not appear widespread enough to warrant a Flash
Flood Watch though.

The wind is expected to shift from the south to the north and
northeast in the wake of the cold front. Low temperatures are
anticipated to be mostly in the 65 to 70 degree range, with some
readings in the lower 60s up north.

Despite ridging building to our north on Thursday, an east to
northeast surface flow (5-10 mph) will keep high temperatures near
normal values in the upper 70s to around 80 degrees. However with
the stalled front beginning to wash out across the area along with
continued moisture return flow overrunning the boundary, a gloomy
and showery day is expected. The high-res guidance continues to
focus much of the shower activity along the I-95 corridor, mainly
into the afternoon hours as more surface based instability builds.
With the continued high PWat values, localized heavy rainfall will
be a threat with this activity, especially in the typical trouble
spots in the urbanized areas. No severe weather is expected
however.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
As we head into the end of the week, we turn our eyes to the
potential coastal system, which looks to remain largely offshore.
While the storm itself looks to remain far enough away to have much
impact across the area, there is still the possibility that there
may be some showers that move in on the east to northeast flow. This
flow should help to keep us more stable so expect it will remain
more showery than thundery as we move through Friday, though some
isolated thunder cannot be ruled out. Additionally, the pressure
gradient will tighten up and it may become quite breezy in the
northeast flow, especially along the immediate coast. With
sufficient cloud cover, we won't be nearly as warm as it has been of
late. Daytime highs will only rise into the 70s to around 80, though
it may feel cooler with the winds blowing. The cloud cover will
remain through Friday night, keeping temperatures from really
bottoming out and they will likely remain the mid to upper 60s
across the region.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
The coastal low will be pulling further away from the area moving
towards the Canadian maritimes on Saturday. A weak boundary may drop
down through the area later Saturday with some low chances for
showers or thunderstorms. Coverage looks to be limited at best as
the energy is fairly week as it cross the region. Highs will rise
into the 70s to lower 80s across the forecast area during the day
with overnight lows dropping into the 60s.

Things really start to look up for the region as we move from
Saturday night into Sunday with surface high pressure slides across
eastern Canada and moves across New England. The high will push
southward into the Mid-Atlantic before starting to shift to the
south, settling off the New England coast through at least midweek.
Meanwhile, we will see substantial ridging develop on Sunday with
the mid level high cresting overhead on Tuesday. Essentially, this
means would should have dry conditions with seasonable temperatures
across the region. High temps Sunday through Wednesday will
generally be in the upper 70s to lower 80s. Overnight lows will be
in the upper 50s to mid 60s, though it may remain closer to the
upper 60s at times along the immediate coast.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Through 00Z...VFR with showers and thunderstorms approaching
RDG/ABE. Winds south to south-southwesterly around 10 kts with gusts
up to 20 kts possible. High confidence.

Tonight...Ceilings increasing in coverage and lowering to MVFR after
00Z at RDG/ABE and near or after 06Z at the I-95 terminals south.
Showers and thunderstorms will accompany the arrival of lowering
ceilings, and a few additional rounds of showers or possibly
thunderstorms are expected through 09-12Z. Winds initially
southerly, then becoming variable before settling out of the east to
northeast around 5 kts by 09Z. Moderate confidence overall.

Thursday...Initially MVFR ceilings with patchy fog possible.
Ceilings are expected to scatter out around 18Z as additional
showers and thunderstorms develop, especially along the I-95
terminals. Winds easterly around 5-10 kts. Moderate confidence.

Outlook...

Friday...Mostly MVFR or lower. Scattered showers and thunderstorms
possible. East-northeast winds around 5 to 15 knots. Moderate
confidence.

Saturday...Mainly VFR. MVFR possible in isolated showers or
thunderstorms during the afternoon. North to northwest winds less
than 10 knots. Moderate confidence.

Sunday through Monday...VFR. North winds around 5 to 10 knots
becoming easterly on Monday. High confidence.

&&

.MARINE...
SCA conditions will continue through much of the evening with seas
around 3-5 feet and southerly winds 20-25 kts. These will diminish
overnight, with winds becoming easterly around 10 kts for Thursday
and seas around 2-4 feet.

Outlook...

Friday...Seas will build and likely exceed 5 feet as a coastal low
passes to the east of the ocean waters. East to northeast winds will
gust around 20 to 25 knots.

Saturday through Monday...Seas and winds are expected to decrease
below SCA criteria during the day on Saturday and then remain below
criteria through Monday.

Rip Currents...

A southerly wind at 15 to 20 MPH is expected for today.
Breaking waves are forecast to build to 2 to 3 feet with a short
to medium period southerly swell. A LOW risk for the
development of rip currents is anticipated along the coasts of
Delaware and New Jersey.

A southeast to east wind is forecast for Thursday and it should
increase to 10 to 15 MPH as the day progresses. A medium period
southeast to east swell is likely and breaking waves should be
1 to 2 feet. The easterly wind is expected to result in a
MODERATE risk for the development of dangerous rip currents on
Thursday.
