Area Forecast Discussion
National Weather Service Mount Holly NJ
312 PM EST Sat Dec 2 2023
.SYNOPSIS...
Low pressure tracking toward Lake Ontario will lift a warm front
into our area by Sunday, before another low develops and tracks off
the coast. Weak high pressure builds in for early next week,
followed by a weak storm system passing by around Tuesday night.
Expect progressively colder temperatures through Thursday as high
pressure builds in for the latter part of next week.
&&
.NEAR TERM /THROUGH SUNDAY/...
A seasonable Saturday occurred north and west of the I-95
corridor under filtered sunshine this afternoon. A much
different story occurred across portions of the Coastal Plain
and I-95 south and east as these areas have been socked under
mostly overcast skies and patchy fog most of the day.
As we head into tonight, skies will quickly cloud back over as the
next low pressure materializes to our southwest. A warm front
positioned across the Chesapeake will gradually lift northward
tonight as low pressure moves into the Tennessee River Valley. By
Sunday morning, low pressure will be located near W PA and will
begin to occlude as a secondary low tracks over VA and eventually
across NJ by Sunday night. Lows will be in the mid 40s to low 50s.
The 12Z guidance suite this morning has slowed down the onset of
rain moving into the area tonight, now beginning between midnight
and 3AM from southwest to northeast. Still the heaviest rain is on
pace to fall between the pre-dawn to late morning hours as low
pressure tracks toward our area. Pockets of heavier rain will begin
to taper off to just some lingering showers by the afternoon as low
pressure tracks overhead and offshore. The exception is across the
higher elevations of NE PA and N NJ where some pockets of light
rain may continue with wrap-around moisture and enhanced lift.
Overall, looking at rainfall amounts between 1/2 to 3/4 of an
inch with localized areas receiving up to 1 inch. Highs on
Sunday are a bit more tricky, ultimately depending on how far
north the warm front makes it. General thinking is for temps in
the mid 40s to low 50s for NE PA and N NJ, mid 50s around Philly
and S NJ and low to mid 60s across the portions of the
Delmarva.
Similar to last night and early this morning, will have to monitor
the potential development for dense fog. Recent HRRR and HREF
surface visibility probabilities less than 1/4 of a mile, have a 50-
60% chance of developing tonight into Sunday. This will be mainly
confined to the Coastal Plain where there will be a more of a
maritime influence and onshore component of the wind. Not enough
confidence at this time to warrant advisories, but something worth
monitoring.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
Sunday night should see any lingering rain lift out of the area by
the first half of the night as warm advection shifts offshore and
the associated upper trough passes by, with winds both at the
surface and aloft turning westerly. The best chance to see
measurable rainfall for the first part of Sunday night will be areas
north of Philadelphia, but PoPs after 00z are only around 40-60%.
Skies should clear as drier air filters in, but lows will be fairly
mild, with upper 30s/low 40s for most of the region.
Monday will be a dry day with at least some partial sunshine for
most, with seasonable highs mainly in the 50s. Clouds may start to
increase, especially by the afternoon as the next upper-level trough
tracks quickly eastward across the Appalachians. However, that
system will lack much moisture, and the surface low will be weak and
stay well south of our region, keeping us dry. Skies may even clear
out Monday night. Will have to keep an eye out for some patchy fog
in sheltered valleys Sunday night and Monday night, but overall
enough westerly winds should limit the fog from being too widespread
or dense.
Expect a dry day Tuesday though any sunshine may be limited to the
morning hours, and from around southern NJ to the Delmarva. Another
shortwave will approach, potentially bringing some unsettled
weather, but any precipitation looks to hold off until Tuesday
night. Highs will be a touch below normal, with low to mid 40s along
and west of the Fall Line with mid to upper 40s from the I-95
corridor to the coast.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Some light precipitation is possible to start the long term period
but the rest of the week after Wednesday looks to be dry.
For Tuesday night into Wednesday, guidance has remained consistent
with the consensus that another wave of upper-level energy develops
and re-amplifies the upper-level trough and begins to dig it out of
the midwest and move it eastward towards the Eastern Seaboard.
Associated with this re-deepening trough is a surface clipper system
that quickly progresses out of the Great Lakes region and into the
Mid-Atlantic during this timeframe. The passage of this system looks
to possibly provide a quick hit of precipitation for Tuesday night
into Wednesday, particularly for the southern half of the area. This
system has been trending colder and drier so PoPs remain around 40-
50 percent at best in Delmarva with lower chances further north. The
colder air does mean though that some snow could be mixed in across
much of southeastern Pennsylvania and western New Jersey,
particularly closer to daybreak Wednesday when surface temperatures
are at their coldest.
The surface low then passes offshore later on Wednesday and model
guidance suggests that it will rapidly strengthen once it does so.
However, guidance continues to suggest that it will be far enough
offshore to result in a minimal effect on the weather in our region.
At this time, the main impacts look to be slightly below normal
temperatures and breezy conditions, particularly closer to the
shore.
Strong high pressure and upper level ridging look to build back in
for Thursday and Friday. Some guidance is suggesting a weak upper-
level trough/surface low may pass through at the end of next week
but this remains highly uncertain at this time. Otherwise, a warming
trend in temperatures back to around normal is expected.

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Tonight..Most terminals will see VFR this evening. KMIV, KILG,
and KACY could remain either MVFR or even IFR due to the low
clouds not scouring out. For the second half of the overnight,
lower CIGS/VSBYS are expected with rain moving in after
midnight. MVFR and/or IFR is once again expected. Light winds.
Moderate confidence.
Sunday...IFR expected in the morning. Slow improvement to MVFR
expected from south to north in the afternoon. NE to E winds to
around 10 kt. Medium confidence with the forecast evolution, but low
confidence on the timing.
Outlook...
Sunday Night...sub-VFR conditions possible, especially in the first
half of the night, as rain lifts out. West/Southwest winds around 5-
10 kt. Low confidence.
Monday through Tuesday...VFR. Westerly winds around 5-10 kt.
Moderate confidence.
Tuesday night and Wednesday...Sub-VFR conditions possible with light
rain. Some snow mixed in is possible Wednesday morning. Winds around
5 knots or less Tuesday night increasing to around 10 knots with
gusts up to 20 knots on Wednesday. Low confidence.
Thursday...VFR. Westerly winds around 10 knots with gust up to 20
knots. Moderate confidence.
&&
.MARINE...
Coastal observations and webcams along the shore continue to show
visibility below 1 mile over the waters. Guidance has been
persistent that low visibility will continue through at least the
early evening. Thus, a Marine Dense Fog Advisory remains in effect
from Manasquan Inlet to Fenwick Island including the Delaware Bay
through 7 PM EST this evening.
Periods of light to moderate rain develop late tonight and taper off
into Sunday afternoon. Light and variable winds will continue
through about midnight. Winds will then gradually become NE-E around
10 kt by Sunday morning and become E-SE winds while increasing to 15-
20 kt by Sunday afternoon. Seas of 3-5 feet.
There may be a few localized gusts near 25 kt between Sandy Hook and
Atlantic City Sunday afternoon as well, however confidence is not
high enough to warrant a Small Craft Advisory at this time.
Outlook...
Sunday Night...Small chance (20-40%) of Small Craft Advisory
conditions. Westerly winds around 15-20 kt, gusting in the low 20s.
Seas 3 to 4 feet, though a brief period of 5 foot seas possible off
the New Jersey coast.
Monday...No marine headlines anticipated. Westerly winds around 15-
20 kt. Seas 2 to 4 feet.
Monday Night...SCA conditions possible (~50%) as westerly winds
around 20 kt and gusts nearing 25 kt. Seas 2 to 3 feet.
Tuesday...No marine headlines anticipated. Northwesterly winds
around 10-20 kt with seas around 2 feet.
Tuesday night...No marine headlines expected. Westerly winds around
10 to 15 knots. Seas of 2 to 4 feet.
Wednesday and Thursday...SCA conditions possible. Northwest to north
winds around 15 knots with gusts around 25 knots, particularly
Wednesday night. Seas of 2 to 4 feet.
