Area Forecast Discussion
National Weather Service Mount Holly NJ
1216 PM EDT Fri Sep 28 2018

.SYNOPSIS...
A weak area of low pressure will move away to our northeast
today. High pressure will build into the region through the
weekend and into the early part of next week. A weak cold front
will sag southward to our north, then transition into a warm
front Sunday into Monday. Another area of low pressure and
attendant cold front may move into the region by mid-week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
The surface low that helped usher in the heavy rain overnight
into earlier this morning continues to lift well to our
northeast through the day. However, a weak surface trough on the
backside of the low has swung across southeast Pennsylvania and
central/southern New Jersey. This has kept the low clouds across
the area, and actually created an area of light rain and
drizzle. This trough will continue to move offshore through this
afternoon and the light rain and drizzle will dissipate into the
early afternoon. The clouds should continue to break up and
scatter out this afternoon and some sunshine continues to be
expected by the afternoon hours, which may allow for many areas
to warm into the 70s, except portions of northeast Pennsylvania
and northern New Jersey where they will likely stay in the 60s.

Winds will begin to shift to the west to northwest if they
haven't already. A few gusts 15-20 mph will occur through this
morning, but gusts will drop off this afternoon.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...
High pressure is forecast to begin building into our region
from the west tonight. As a result, we are anticipating a mostly
clear sky and a light wind. Low temperatures should be mostly
in the 50s.

Some late night valley fog is possible in eastern Pennsylvania
and northern New Jersey.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Summary...we look to finally get a much-needed break from the
persistent wet pattern - at least through the early part of next
week. High pressure will gradually build into the region as the
weak area of low pressure moves eastward over the Atlantic.
Zonal flow will persist over the region as a synoptic trough to
our north progresses eastward, leaving us south of the main jet.

Saturday through Monday night...The main area of rain
associated with the ripple of low pressure will continue to exit
to our east on Saturday. Highs will be a little above average
in the mid 70s. Sunday, mid-level flow turns a little more west
to northwesterly, and drier air finally pushes into the area.
Dew points look to drop below 60 for most of the area, possible
remaining in the 40s in the higher terrain in the Poconos. A
short wave trough will pass through the synoptic trough to our
north Sunday, while at the surface a weak cold front attempts to
push southward into the area. Models have continued to back off
on the intensity of the front so it likely won't make much
progress, so highs will only be a few degrees cooler than
Saturday. The front then transitions into a warm front Monday
and winds turn more southwesterly. Thus, highs return to above
average Monday in the mid to upper 70s. Humidity will increase a
little with dew points returning to the 60s. Model consensus
keeps the area dry with rain staying to our north along the
lifting warm front. Overall, we look to finally have a nice
weekend for once!

Tuesday through Thursday...Upper ridge of high pressure to our
south will keep the area under predominately westerly flow aloft
through the end of the period. During this time, a series of
shortwaves pass to our north across the Saint Lawrence River
Valley. Medium range models differ considerably with regard to
the exact strength and timing of these features and the ultimate
pattern evolution yielding considerable uncertainty in the
forecast for this period. As far as sensible weather is
concerned, temps are expected to be a few degrees above normal
with dewpoints in the lower 60s with light southerly to westerly
surface flow through the middle of the week. Skies will be
partly to mostly cloudy with generally more coverage toward the
north. Will maintain slight to low end chance PoPs for mostly
diurnally driven showers and thunderstorms through mid-week as
well given the proximity of the shortwaves passing to our north.

Although details are still uncertain at this range, medium
range model indicate that a cold front will be passing through
the northeastern US by the end of the period Thursday. This
frontal passage will bring an increased chance for showers and
thunderstorms along with cooler and drier air in its wake across
the region by the end of the week. As previously mentioned,
guidance varies considerably regarding timing and strength of
this feature.

.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Today...The low ceilings continue to hang around early this
afternoon, but are starting to lift across the area. Most places
have return to MVFR except ACY/MIV/TTN which will remain IFR for
a couple of more hours. MVFR ceilings will continue into the
afternoon, but VFR ceilings are expected to return later this
afternoon into this evening.

Winds have turned more north-northeast from Philadelphia
northward. This north-northeast wind will continue for another
couple of hours, but will become more northwesterly through the
afternoon. Winds speeds are around 10 knots.

Tonight...VFR with a mainly clear sky. Patchy valley fog is
possible around KRDG and KABE. Variable wind 6 knots or less.

OUTLOOK...
Saturday through Tuesday...VFR conditions expected with mostly
light and variable winds. There is a slight chance for showers
and lower flight categories late Monday night into Tuesday.

&&

.MARINE...
The Small Craft Advisory was extended across the northern New
Jersey atlantic coastal waters through 4 pm as winds remain
around 25 knots and seas hover around 5 feet. However,
conditions are subsiding elsewhere, so the remainder of the
advisory was allowed to expire at noon.

OUTLOOK... Saturday through Tuesday...winds and seas should
stay below SCA criteria on all waters.

Rip Currents...
A moderate risk for the development of dangerous rip currents
is expected for today. There should be a chaotic mix of swells
ranging from the northeast to the south along with breaking
waves around 2 to 3 feet.

The final surf zone forecast for this season will be issued on
Sunday morning, September 30. Surf zone forecasts will resume
next May.
