Area Forecast Discussion
National Weather Service Mount Holly NJ
255 PM EDT Mon Sep 12 2022

.SYNOPSIS...
Low pressure will pass from the Great Lakes region and north of our
area through Tuesday. This will push a cold front toward the area
overnight before crossing the area on Tuesday. A period of scattered
to numerous showers and storms associated with this system is
expected to impact the area through early Tuesday. A secondary cold
front will pass through the area late Wednesday, then strong and dry
high pressure will build and prevail across the region through the
end of the week. The high pressure will provide and extended period
of seasonable, pleasant, and dry conditions through at least
Saturday with the high pressure pushing offshore over the
weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
Low clouds will gradually lift into this evening, but skies
remain cloudy, and conditions will be warm and humid. There may
be some breaks in the clouds from time to time which would
allow temperatures to climb into the lower 80s. Along with
surface dew points in the upper 60s to low 70s, it will be warm
and humid.

Surface cold front is moving through western New York and
western Pennsylvania, and this front slowly tracks east
tonight. Meanwhile, a closed upper low over the lower Great
Lakes tracks east towards western New York and western
Pennsylvania tonight, then tracks northeast into eastern Canada
during the day Tuesday. A secondary cold front then passes
through the region Tuesday afternoon.

SB CAPE values range from 500 to 1000 J/kg across northern New
Jersey and the southern Poconos, and from 2000 to 2500 J/kg in
Delmarva. PWATs currently around 1.7 inches will rise to around
2 inches as east to southeast flow increases ahead of the
approaching cold front. Weak surface low pressure develops this
evening, then lifts along the I-95 corridor through the
overnight hours.

One round of showers and thunderstorms will develop ahead of
the approaching cold front by this evening. Locally heavy rain
and gusty winds are possible in the stronger of the storms, but
widespread severe thunderstorms not expected. Latest models and
most of the CAMS seem to have slowed down the first round of
convection, then the convection ramps up again tonight with the
development and passage of that weak low. While the threat for
convection diminishes a bit with the loss of diurnal heating,
the threat for heavy rain and localized flooding will continue.

Convection tapers off from south to north after midnight, with
showers and thunderstorms continuing across northern New Jersey
and the southern Poconos into daybreak or so Tuesday.

Initial cold front passes through the region during the
overnight. However, surface winds remain nearly calm, so not
expecting a surge of drier air into the region. As a result, can
expect fog and low stratus to develop after the rain ends, and
it looks like the fog and stratus may continue through late
Tuesday morning.

The secondary front passes through the region by midday
Tuesday. At that time, winds turn west-northwest and increase to
10 to 15 mph with occasional gusts to 20 mph. Surface dew
points tumble into the 50s, and skies clear out, becoming sunny
by late afternoon.

Warm and humid tonight with lows in the 60s and 70s, and then
highs on Tuesday will be in the upper 70s to low 80s.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
A trough axis will lift well northeast of the area Tuesday night
through Wednesday. Ridging will build just to the west of the area
then prevail through the end of the week. A cold front associated
with the departing trough will be located offshore by Tuesday
evening and will be well offshore by Wednesday morning as strong
high pressure settles southeastward from the Great Lakes and
southeastern Canada. This pattern will result in rather pleasant and
seasonable weather conditions across the region likely lasting
through at least Saturday.

Dewpoints will most notably fall in the wake of the cold front,
especially Thursday as deeper boundary layer mixing occurs and
cooler and drier air arrives from the northwest. Dewpoints will fall
well into the 40s across Pennsylvania and New Jersey by Thursday
afternoon. Expect highs Wednesday to be within a couple degrees of
80 across most areas and from the mid 70s to around 80 degrees on
Thursday. The pressure gradient in place across the area should
prevent temperatures from falling too much overnight, so expect lows
in the mid to upper 50s Tuesday night and Wednesday night despite
the drier air. Skies will be mostly clear/sunny. Winds will prevail
from the west to northwest Wednesday around 10-15 mph and become
more northerly for Thursday. The winds will diminish to around 5 mph
or less at night.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
The dry high pressure will continue to prevail across the region
from Thursday night through at least Saturday. Surface ridging will
shift offshore into Saturday though, and weak south to southwesterly
return flow will begin to advect slightly warmer and more humid air
back into the area.

Thursday night will probably feature the coolest temperatures so far
this climatological autumn for most of the area. Expect low
temperatures in the mid to upper 40s from generally near and north
of I-78 with perhaps a few of the typical sheltered spots dropping
to the upper 30s near/north of I-80. Low to mid 50s should be common
elsewhere. Clear skies will continue with the high pressure
centering itself just northwest of our area. Friday will be another
beautiful day with highs in the mid to upper 70s, sunny skies, and
dewpoints in the low to mid 40s. Winds will also be less than
Wednesday and Thursday, generally around 5-10 mph from the
northwest. Temperatures and dewpoints will begin to rebound into the
weekend as the high shifts offshore and weak southerly return flow
sets up. Conditions will still be quite pleasant though, with highs
in the low to mid 80s and dewpoints around 60 degrees. Lows will
range from around 50 to 60 degrees.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Through this evening (until 00Z)...MVFR/low-end VFR CIGs,
becoming MVFR by 00Z. Some SHRA with scattered TSRA will
primarily affect KRDG/KABE, but cannot rule out convection
impacting the other terminals prior to 00Z. Light E-SE winds.
Moderate confidence.

Tonight (00Z through 12Z)...IFR conditions in SHRA/TSRA.
Convection lasts through 06Z or so, and ends from south to
north. LIFR CIGs along with MVFR/IFR VSBYs will develop in
stratus and fog after 06Z. LGT/VRB to nearly calm winds.
Moderate confidence.

Tuesday...Sub-VFR conditions in stratus/BR through 15Z or so.
VFR thereafter. Light W-NW winds, increasing to around 10 kt
with gusts to 15 kt int he afternoon. Moderate confidence.

Outlook...

Tuesday night...VFR with clearing skies. Winds west to northwest
around 5 kts. High confidence.

Wednesday...VFR/SKC. West to northwest winds around 10 kts. A few
gusts around 15-18 kts possible. High confidence.

Wednesday night...VFR/SKC. West to northwest winds around 5 kts.
High confidence.

Thursday...VFR/SKC. North to northwest winds around 10-15 kts. A few
gusts around 18-20 kts possible. High confidence.

Thursday night...VFR/SKC. Northerly winds around 5 kts or less. High
confidence.

Friday...VFR/SKC. North to northwest winds around 5-10 kts. High
confidence.

Friday night...VFR. Light and variable winds. High confidence.

Saturday...VFR. Southerly winds around 5-10 kts. High
confidence..

&&

.MARINE...
Will continue the Small Craft Advisory for southern NJ and DE
ocean waters through 7 pm as seas remain around 6 feet.
Otherwise, sub-SCA conditions on the northern NJ ocean waters
and DE Bay.

Winds become W-SW 10 to 15 kt on Tuesday.

VSBY restrictions in showers and thunderstorms tonight. Winds
and seas locally higher in thunderstorms.

Outlook...

Conditions are forecast to remain below advisory criteria from
Tuesday night through Saturday. Winds mainly from the west to
northwest around 10-15 kts Tuesday night through Wednesday night
becoming northerly on Thursday. Gusts up to 20 kts are possible
on Thursday. Winds will shift northeast to easterly on Friday
then southerly on Saturday. 3 to 4 foot seas Tuesday night will
gradually diminish to around 1 to 2 feet by Thursday evening.

Rip currents...

For the rest of today, with swells remaining quite long with a
14 second period expected, this will enhance the rip risk to
HIGH. As a reminder, many beaches now have limited to no
lifeguards present.

For Tuesday, even though swells remain long with 12 seconds,
waves lower some, so the rip risk will be MODERATE.

&&
