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, 4:23 PM EST, 5 minutes earlier.

Area forecast discussion, Dec 18, 4:23 PM EST, 5 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
423 PM EST Mon Dec 18 2023

.SYNOPSIS...
Strong low pressure over Quebec this evening will continue to move
northeast tonight and Tuesday. A cold front will cross the area overnight.
High pressure well to the west will gradually build over the Middle
Atlantic this week then move offshore during the weekend. A system
may affect the area for the start of next week.

&&

.NEAR TERM /THROUGH TUESDAY/...
Widespread heavy rainfall last night and this morning have 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 was cancelled earlier. 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 quieter
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 NIGHT THROUGH WEDNESDAY NIGHT/...
The midweek period will feature quiet, benign weather, with
generally clear skies and easing winds. Surface high pressure will
continue to build eastward and expand across the just about the
entire eastern half of the country Tuesday night into Wednesday. An
upper-level trough associated with the Sunday/Monday strong coastal
storm will continue to weaken and push off the East Coast by Tuesday
night, taking any source for forcing for precipitation or moisture
for cloud cover along with it. Cool northwest flow in the low levels
will advect very dry air in Tuesday night into Wednesday, with
dewpoints dropping into at least the low 20s, with some teens likely
mainly northwest of I-95. Easing winds and clear skies will favor
good radiational cooling conditions, with some of the coldest
morning lows set for Wednesday morning; low 20s forecast in many
areas outside of the urban corridor, and even some upper teens
possible near the Poconos or the deepest part of the NJ pine
barrens. Would not rule out some patchy shallow fog given very
saturated ground conditions, but drying winds on Tuesday and
continued dry air pushing in should limit the fog from being more
than just that.

Wednesday will be a sunny, dry day with highs mainly in the 40s, and
fairly light winds. As mid and upper-level ridging builds in across
the eastern part of the country as well, warmer air will begin to
push in aloft, modifying temperatures and making for more stable
atmospheric conditions. Clear skies will continue into Wednesday
night, setting us up for another chilly night, but lows by Thursday
morning will tend a few degrees milder than the past night as the
airmass gradually modifies.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
High pressure at the surface and an upper ridge that build in for
the midweek period will continue for the end of the week and then
into the weekend. A weak system may bring some cloudiness for a time
Sat./Sun. but no precipitation is expected. The next chance for
rains (most likely) will be later Monday (Christmas) when we will
have some chance pops in the forecast.

Much like the past few weeks, cool or near normal temperatures for
the end of the week, then above normal readings expected for the
weekend and into Monday. We could have some upper 40s/low 50s for
highs on Christmas. If so, that would be 4 to 6 degrees above normal
for the last week of December.

&&

.AVIATION /21Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

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.

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

Outlook...

Tuesday night through Wednesday night...VFR conditions. Some patchy
shallow fog with localized MVFR at some of the more rural TAF sites
like RDG/MIV, perhaps even ABE or TTN cannot be completely ruled out
early Wednesday morning. Otherwise expect clear skies and light NW
winds generally 5-10 kt; lighter nights/mornings.

Wednesday through Saturday...VFR. W to 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 night through Wednesday night...Small Craft Advisories will
remain in effect for the entire period, mainly because seas from the
Sunday/Monday strong coastal storm will be slow to lower; 5-7 ft
early Wednesday, down to 4-6 ft by early Thursday. Winds will remain
NW, with some gusts to 25 kt Tuesday evening. Those winds will ease
to 10-15 kt for most of Wednesday.

Thu/Thu night/Friday... SCA seas continue on the ocean. Fair.

Friday night... SCA early then sub-SCA possible late. Fair.

&&

.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 and the
Atlantic Coast 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.

Minor to moderate flooding continues along portions of the back bays
of coastal Monmouth and Ocean Counties, so the Coastal Flood Warning
continues for these areas. High tide has passed, and water levels
should begin to recede into this evening.

The Coastal Flood Advisory was extended for Sussex County (DE) as
some minor flooding continues along the back bays. High tide has
passed, and water levels should begin to recede into this evening.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...Coastal Flood Advisory until 9 PM EST this evening for PAZ070-
     071-106.
NJ...Coastal Flood Warning until 5 PM EST this afternoon for NJZ013-
