What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this river flood warning went out at Dec 11, 1:06 AM EST, 1 hour 56 minutes earlier.

Area forecast discussion, Dec 11, 1:06 AM EST, 1 hour 56 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
106 AM EST Mon Dec 11 2023

.SYNOPSIS...
A strong cold front will push offshore through today as low
pressure moves into southern new England. 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 TODAY/...
The storm system continues to work its way through the region.
Widespread rain, locally heavy, continues to impact portion of
the region. The cold front has pushed offshore as of 1 AM, and
low pressure will develop along the front as it departs offshore
to the east. Behind the cold front, winds have shifted to the
northwest and generally range from 10-20 mph with gusts near
25-30 mph at times. Winds may lessen a bit over the next few
hours until near daybreak when the deeper cold advection arrives
and precipitation ends, helping to increase boundary layer
mixing.

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.
Additional rainfall amounts of a half to 1 inch may occur until
precip ends. Streams and creeks continue to rise across the area
and slower responding main stems rivers will follow suit during
the daytime Monday.

Behind the cold front, cold air advection will be underway, and
temperatures will drop to freezing in the higher elevations
northwest. Rain will mix with and change to snow late
tonight/early Monday morning in the southern Poconos, Lehigh
Valley, and northern New Jersey. Mount Pocono has already
changed over to light snow as of 12:30 AM. A Winter Weather
Advisory remains in effect for Carbon and Monroe counties, as 2
to 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.

Temperatures will continue to fall 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 /TONIGHT 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 /06Z MONDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas...

Tonight...Widespread rain with MVFR to IFR conditions that will
begin to improve towards 12Z as precip tapers off from west to
east. A period of RASN is possible at all sites outside of
MIV/ACY from around 09-14Z. Northwest winds near 10-15 kt with
20-25 kt gusts. Moderate confidence.

Monday...IFR/MVFR conditions early, then VFR by 14Z to 15Z from
west to east. Northwest 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...
Winds have shifted to the northwest behind a cold front that
passed offshore just after midnight. Winds will then increase
to 20-30 kts by daybreak, when gusts of 40-45 kts are forecast
across the Atlantic waters. Winds then diminish later Monday
afternoon into Monday evening. A Gale Warning remains in effect
for all coastal waters.

Widespread moderate to heavy rain and perhaps some thunder will
continue 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 heaviest rain has already ended. 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.
