What forecasters said that day

The local office's own words before this areal 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 areal flood warning went out at Dec 18, 1:42 PM EST, 4 minutes earlier.

Area forecast discussion, Dec 18, 1:42 PM EST, 4 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
142 PM EST Mon Dec 18 2023

.SYNOPSIS...
Strengthening area of low pressure will move across our area
later this morning and lift north and east into south-eastern
Canada by this evening. An upper trough with a surface cold
front will pass through the region on Tuesday. High pressure
then builds east through the end of the work week. Another weak
cold front may approach for Saturday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 130 AM...Widespread heavy rainfall has lead to an active
afternoon of river flooding across the region. Dry air is
filtering in so the threat of new flooding from additional
rainfall is over. So the flood watch has been cancelled, however
there are still forecasts of additional flooding on the slower
responding rivers so the threat of flooding is still on going.
Much of the Passaic basin is forecast to move into Major flood
stage with much of the Raritan basin forecast to be in moderate.
Please refer to Flood Warnings for the latest information on
forecast flooding and impacts.

From a sensible weather discussion, subsidence associated from
cooling on the back side of the trough should lead to a brief
window of calm weather tonight with lows dropping to near
freezing. As winds decouple overnight our gusty winds will also
drop dramatically and turn west southwest. As the trough exits
north and east, another closed 500mb low will start to swing
through the region. Most of the area will remain dry, but in
the higher elevations of the Poconos, Lehigh Valley and Northern
NJ, 925mb warm air advection should produce enough lift to tap
into a saturated DGZ allowing for snow to fall. Totals will
generally be around a trace to 0.2" but if the forcing ends up
being slight stronger some of the higher elevation sites could
end up with close to 1/2".

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
Tuesday should be breezy. The tightest low/mid level height
gradient and tightest surface pressure gradient never quite line
up perfectly, so max wind gusts are likely to be in the 25 to
30 mph range (possibly as high as 35 mph on ridge lines).

Once this trough slides east of our region Tuesday night into
Wednesday, it should kick off a return to dry conditions and
seasonable temperatures.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
The trend of dry and seasonable is expected to continue
Thursday and Friday as a broad surface high pressure system will
gradually build eastward towards our region.

In the upper levels, a broad ridge becomes entrenched over the
eastern U.S.. Several models depict a short wave trough sliding
eastward to the south of the ridge, which could result in
precipitation by next weekend, but once again, moisture will be
limited. Additionally, depending on how robust the ridge is, the
short wave trough may weaken as it tries to undercut it. All
that being said, stayed with the previous forecast in keeping
slight chance pops on Saturday.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Rest of Today...MVFR becoming VFR as the heavy rains have moved
out of the region. W-NW winds between 15-25 kt with gusts up to
30-35 kt possible. Moderate confidence.

Tonight...VFR expected at all terminals. Winds diminish to SW-W
around 10-15 kt. Isolated chance of a snow shower at KABE, otherwise
remaining dry at all terminals. Moderate confidence.

Outlook...
Tuesday...VFR expected. SW winds 10 to 15 KT becoming
northwesterly 10 to 20 mph with gusts up to 30 mph. Moderate
confidence.

Wednesday through Friday...VFR. NW winds 5 to 15 kt. High
confidence.

&&

.MARINE...
A Gale Warning remains in effect through 6 PM today. SE winds around
30-35 kt sustained with gusts up to 40-45 kt will continue through
this morning. As the low passes by later this morning, winds
will switch around to the W-NW and be sustained around 25-30 kt
with gusts up to 30-40 kt through this afternoon. Seas ranging
from 14-18 feet with localized seas up to 20 feet possible
through today.

For tonight, Small Craft Advisory conditions will continue as winds
diminish and gradually become SW-W around 15-20 kt with gusts up to
25 kt. Seas likewise will gradually lower as well between 10-14
feet.

Outlook...

Tuesday...SCA conditions are expected on all waters both due to
NW winds gusting up to 30 kt, and elevated seas primarily on
the Atlantic coastal waters.

Tuesday night through Friday...Once winds diminish, no
additional SCA conditions are likely on the Delaware Bay. On the
Atlantic coastal waters elevated seas may linger for most, if
not all of this period.

&&

.HYDROLOGY...
Active Flood Warnings are in effect, please continue to monitor
information from Law Enforcement, local media, and heed any
warnings in effect. Avoid flooded roadways and when safely
possible please pass along flood reports to the NWS.

&&

.TIDES/COASTAL FLOODING...
The Coastal Flood Warning for the tidal Delaware River and the
Coastal Flood Advisory for portions of the eastern MD shore
have been allowed to expire. High tide has passed and water
levels will continue to recede. However, excessive runoff from
rainfall may continue to result in flooding of roadways and
urbanized areas, especially near tidal waterways.

The onshore surge will last the longest across the central to
especially northern portions of the New Jersey coast. Widespread
minor tidal flooding is expected with the midday high tide,
although this may subside more by later today as the winds turn
offshore and strengthen. Water will likely be trapped for a
while in Barnegat Bay (Ocean County) as the flow turns offshore
and the water, including runoff, sloshes around. Due to a
combination of freshwater runoff from the heavy rain, latest
observations indicating the surge being slower to drain out of
Barnegat Bay, and westerly winds pushing the water toward the
bay side of the barrier island, areas of Moderate coastal
flooding are now anticipated. Thus, Monmouth and Ocean Counties
were upgraded to a Coastal FLood Warning for the midday high
tide cycle.

Farther south for the Atlantic coast of Sussex County, Delaware,
mostly back bay flooding should continue for a while today and
therefore maintained the Coastal Flood Advisory for now.
