Area forecast discussion, Dec 10, 10:02 PM EST, 1 hour 40 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1002 PM EST Sun Dec 10 2023
.SYNOPSIS...
Low pressure and a strong cold front cross the area tonight and
then move towards New England Monday. High pressure builds in
behind the low for the start of the week. A weak cold front
drops though the area early Wednesday. More high pressure
returns for the end of the week.
&&
.NEAR TERM /THROUGH MONDAY/...
The storm system continues to work its way through the region.
Widespread rain, locally heavy, continues to impact mostly New
Jersey south of I-195 and Delmarva. Cold front is through most
of eastern Pennsylvania and is now entering western New Jersey
and Delmarva. Low pressure is over the Southeast, and that low
will track north along the coast and along the front. Behind
the cold front, winds have shifted to the west-northwest. There
is a strong low level jet, generally 40 to 50 kt, along the New
Jersey coast, but the strongest winds are not mixing down given
how warm the ocean is. Surface obs near the coast are generally
reporting 30 to 35 mph gusts. Will go ahead and cancel the Wind
Advisory, these winds are below Wind Advisory criteria.
Between 1 and 2 inches of rain has fallen across the region,
with the heaviest rain along the I-95 corridor, and into
southeast New Jersey and Delmarva. Flood Advisories are in
effect for the greater Philadelphia area, and there are Flood
Warnings along the New Jersey coast. Along the coast, flooding
may be a combination of both heavy rain and high tide. Since
rainfall has not quite been as heavy in the southern Poconos,
the Lehigh Valley, and northern New Jersey, and the heaviest
additional rainfall will be south and east of the I-95 corridor,
will go ahead and cancel the Flood Watch for the northern zones.
Flood Watch remains up for all other areas through Monday.
Behind the cold front, strong cold air advection will be
underway, and temperatures will drop to freezing. Rain will mix
with and change to snow late tonight/early Monday morning in the
southern Poconos, Lehigh Valley, and northern New Jersey. A
Winter Weather Advisory remains in effect for Carbon and Monroe
counties, as 3 inches or so of snow is expected. Elsewhere, snow
totals will be 1 inch or less.
Following frontal passage, high pressure behind the front will
build in Monday as precipitation tapers off, but WNW winds will
remain gusty through the afternoon.
Otherwise, expect a sharp drop in temperatures into the 40s
tonight behind the cold front with temperatures in the 30s by
daybreak Monday. Northwest winds will become quite breezy
overnight with gusts remaining near 25-35 mph as the surface low
strengthens rapidly offshore.
Last, but not least, is the expected rain to snow transition on
the back side of the departing system Monday morning for areas
near and especially northwest of I-95. Guidance has come to a
rather good consensus that some precipitation will linger across
the area around daybreak to perhaps a few hours after daybreak
as colder WNW flow takes over the region. Areas northwest of the
I-95 urban corridor (primarily Poconos, Lehigh Valley, and
northwest NJ) are expected to see a transition to a period of
snow before the precipitation exits the area. This transition
may occur as far south as the urban corridor Monday morning.
Accumulating snow is forecast primarily for higher elevations
near and above 1,000 feet in eastern Pennsylvania and northwest
New Jersey. Across the Pocono Plateau, temperatures will drop
low enough to support snow accumulations of 2-3 inches with
potential for amounts near 5 inches possible above 1,800 feet. A
Winter Weather Advisory has been issued from midnight through
noon Monday. The snowfall will likely impact the Monday morning
commute in these areas.
Farther southeast and at lower elevations, temperatures will likely
be too warm to support snowfall accumulation even where a transition
to snow does occur. A dusting is possible into the I-78 corridor,
Berks County, and western Chester County, however significant travel
impacts are currently unlikely aside from a few slippery spots on
the roads.
Aside from the snow potential, Monday will be a cold and blustery
day with temperatures struggling to climb into the 40s. Winds will
peak by late morning and early afternoon near 15-25 mph with gusts
of 30-40 mph possible throughout the day. Some clearing may occur
immediately following the end of the precipitation in the morning,
however stratocumulus will likely develop in its wake during the
afternoon. Some light snow showers may linger in the southern
Poconos.
&&
.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
Once the system from the near term clears the area on Monday,
rather tranquil weather is expected for Mon night into early
Wednesday. The deep surface low near New Brunswick Monday evening
will pull further NE while expanding high pressure to our southwest
builds in. The will bring a period of dry weather with decreasing
winds Mon night. Fair weather continue through Tue night.
Temperatures will be below normal into early Wednesday with
lows Mon night in the 20s and a few degrees milder Tue night
when some areas will have lows in the low 30s. Highs will favor
the ow/mid 40s for Tue with readings remaining in the 30s for
north NJ and the higher elevations of the Poconos.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
There is not much excitement for the weather in the long term as we
head into mid-December. A Northeast US upper trough remains put Wed/Thu
before flattening and moving away for the Fri/Sat. A surface ridge
remains across the area much of the time. A dry cold front drops
across the region Wed. reinforcing the cool airmass already in place.
These factors point to a dry forecast with zero, or close to it,
for Wed thru Sat. Temperatures will be near normal or perhaps a few
degrees below for Wed/Thu (following the front) then temps will go
above normal for Fri/Sat. We'll have high temps in the low 50s next
Sat for Delmarva and south NJ while north NJ and the Poconos will
have highs in the mid/upper 40s.
&&
.AVIATION /03Z MONDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas...
Tonight...Widespread rain with IFR and LIFR conditions that will
improve to MVFR towards 12Z as precip tapers off from west to
east. A period of RASN is possible at KRDG/KABE late in the
period. Winds will be S 10 to 15 kt ahead of the front, with
winds at KACY 15 to 20 kt with gusts up to 30 kt. Behind the
front, winds abruptly shift to the W-NW at 15 to 20 kt with 25
to 30 kt gusts. Along with S winds, there is 45 to 55 kt of LLWS
at 2000 feet. Once winds shift to the west, that LLJ will push
offshore. Moderate confidence.
Monday...IFR/MVFR conditions early, then VFR by 14Z to 15Z from
west to east. A brief period of -RASN at KRDG/KABE with a brief
period of -SN at KABE. W-NW winds 15 to 25 kt with 25 to 35 kt
gusts. Moderate confidence.
Outlook...
Mon night... VFR. Decreasing winds during the evening.
Tue thru Friday... VFR expected. Gusty winds possible Wed.
&&
.MARINE...
Southerly winds will increase to gale force late this evening across
the Atlantic waters and across the Delaware Bay. Southerly winds will
peak late this evening near 20-30 kts with gusts of 30-40 kts. The
winds will shift abruptly to the northwest as a cold front passes
offshore around midnight. Winds will then increase to gale force
again by Monday morning, when gusts up to 45 kts are possible across
the Atlantic waters. Winds then diminish Monday afternoon into Monday
evening.
Widespread moderate to heavy rain and perhaps some thunder will move
through, especially this evening with visibility 1-3 NM. The rain
will end by Monday morning.
Outlook...
Mon night...Gale flags from Mon will likely be replaced with SCA
flags until seas settle. Fair weather.
Tue/Tue night/Wed... sub-SCA. Fair.
Wed night/Thu ... SCA winds/seas possible. Fair.
&&
.HYDROLOGY...
A Flood Watch continues for the forecast area
through Monday afternoon, though the rain will be heaviest this
evening, then taper off Monday morning. Low pressure and a potent
cold front is still expected to bring total amounts of 2 to 3 inches
of rain to the region. As of early Sunday evening, already 1 to 1.5
inches has already fallen across portions of southern DE and NJ, so
it is very possible those areas may approach the 3" mark before the
rain tapers off early Monday morning. Excessive runoff may result in
some flooding of creeks, streams, and other low- lying and flood-
prone locations. Most mainstem rivers are currently not forecast to
go into flood, however minor flooding is forecast at Pine Brook on
the Passaic River and Blackwells Mills on the Millstone River. If
higher rainfall rates occur, some of the fast responding creeks may
go into flood especially in southeastern Pennsylvania.
&&
.TIDES/COASTAL FLOODING...
Persistent and increasing southerly winds will allow for a buildup
of water in Barnegat Bay tonight before a cold front passes through
on Monday morning. Winds then shift to a west-northwest flow at
20 to 30 mph with gusts up to 40 mph. This will push that excess
water into the back bays of Barnegat Bay along coastal Ocean County.
Minor inundation on the most vulnerable roads is likely, and cannot
rule out spotty moderate coastal flooding, especially near Mantoloking.
Spotty minor flooding also cannot be ruled out for other back bay
coastal communities in NJ and DE.
