What forecasters said that day

The local office's own words before this dense fog advisory 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 dense fog advisory went out at Dec 9, 12:42 AM EST, 2 hours 24 minutes earlier.

Area forecast discussion, Dec 9, 12:42 AM EST, 2 hours 24 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1242 AM EST Sat Dec 9 2023

.SYNOPSIS...
The region will feel the influence of surface high pressure to the
south through today. A potent cold front approaches tonight and
Sunday. Potent cold front crosses through Sunday night. High
pressure begins to build in Monday and holds a firm grasp over
the region to the end of the week.

&&

.NEAR TERM /THROUGH TODAY/...
Quiet weather for the near term. One challenge, for the
overnight, will be deciding how much and how dense any fog will
be. Overall, a decent setup for radiational cooling, but a dry
air mass in place. Increased mention of fog overnight and
included mention of freezing fog where temperatures are at or
below freezing. Clear to partly cloudy skies otherwise with
lows in the low/mid 30s most spots. Light E/SE winds.

A great weather day Saturday with partly to mostly cloudy skies
and mild temperatures. Highs will reach the low/mid 50s for the
areas N/W of the fall- line and upper 50s/low 60s for Delmarva,
metro Philadelphia and srn NJ. Mostly South winds 5 to 10 mph.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY/...
Bottom Line...A potent cold front undergoing significant
frontogenesis will cross through the region Sunday night. This
will bring a handful of weather impacts to the region Sunday
into Monday including strong winds, heavy rain, freshwater and
tidal flooding concerns.

Synoptic Pattern...A potent cold front to our west will further
approach Saturday night, and look to cross through during the
Sunday night period. Following passage, high pressure behind the
front will build in Monday as precipitation tapers off.

Saturday night...Winds are forecast to be light for many areas
during the first half of the period. With continued moisture
and warm air advection during this period, it is possible that
fog develops across areas in the region. It is even possible
that some marine fog develops early in the period before
winds/gusts pick up later on. Forecaster confidence in fog
development is low to moderate, so will refrain from discussing
visibilities and density of fog for now. In the second half of
the period, there are slight chances and chances of
precipitation for area.

Sunday...By Sunday morning, the pressure gradient will begin to
increase and therefore, a increase in winds and gusts will be
felt across the region. Precipitation will likely arrive in our
western areas in the morning and will increase in magnitude
while spreading eastward with time. By the afternoon, moderate,
to heavy rain at times, is expected across the region. Winds
will be 15-20 mph sustained with gusts of 30-45 mph possible.
Those higher gusts of 40-45 mph will be felt closer to coastal
areas.

Sunday night...Heaviest of rainfall is expected to drape
eastward with time. Pressure gradient will only increase, with
the entire region looking to see 20-30 mph winds with gusts up
to 35-45 mph.

Monday...Lingering precipitation behind the cold front will linger
some. Our more western areas (primarily Poconos and Sussex
County NJ) may see some snow mixed with rain with the cold
advection; otherwise, rain is expected for all other areas
given the situation. Precipitation chances will taper off with
time. No precipitation is expected by the afternoon. Winds and
gusts will remain the same magnitude from the previous period,
only in the late afternoon/evening will they begin to decrease.

Models indicate mesoscale banding and significant frontogenesis
will occur with the system as well as elevated instability.
Mesoscale guidance will have be watched going forward. 2.0-3.0
inches of rain are expected with locally higher amounts
possible. WPC maintains all of our region in a MARGINAL risk for
excessive rainfall with northern NJ in a SLIGHT risk for
excessive rainfall (see HYDROLOGY section for more details).
Strong winds are expected Sunday through Monday as discussed.
Wind advisories for the coastal areas is a certainty; high wind
watches/warnings are possible for the same areas. High winds
will contribute to growing coastal flooding concerns as well as
proximity of the event to the new moon on December 12th.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
Latest ensemble and deterministic model guidance indicates the long
term will be dominated by surface high pressure. Given almost no
divergence among guidance for this situation and the overall
synoptic pattern, forecaster confidence in the forecast is high.

Overall, with surface high pressure in control expect a quiet long
term weather wise. Precipitation during the term is not expected; no
PoPs are included in the forecast. Temperatures will likely run
right around normal through the term.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas...

Tonight...VFR initially, then IFR CIGs/VSBYs will develop in the
pre-dawn hours of Saturday in fog/stratus. Light winds favoring
an east to southeast direction. Low confidence on exact timing
of lowering conditions.

Saturday...VFR after any lingering fog/stratus diminishes. High
clouds expected. South winds increasing to 5 to 10 knots.
Medium/high confid.

Outlook...

Saturday night...Sub-VFR with fog possible. Ceilings will develop
and drop through the period. Chance of -RA. S/SE winds 5-10 knots.
Low confidence.

Sunday...Sub-VFR. RA with RA+ possible at times. S winds increasing
to 15-20 knots with gusts up to 25-30 knots. Moderate confidence.

Sunday night...Sub-VFR. RA/+RA. S winds 20-25 knots with frequent
gusts of 30-40 knots will veer westerly after strong cold frontal
passage. Moderate confidence.

Monday...Sub-VFR ceilings lingering in the morning will give way to
mainly VFR conditions by the afternoon. W/NW winds 20-25 knots with
frequent gusts of 30-40 knots. Moderate confidence.

Tuesday...VFR. W/SW winds around 10 knots. High confidence.

Wednesday...VFR. W winds around 10 knots. High confidence.

&&

.MARINE...
Overall, tranquil weather tonight and Saturday. There could be some
patchy fog towards morning. Sub-SCA winds and seas. Winds
mostly South to Southeast around 10 knots.

Outlook...

Saturday night...No marine headlines anticipated.

Sunday...Gales with seas building up to 7-9 feet. Gale Watch is
in effect.

Sunday night...Gales. Storm force winds possible. Seas 8-12
feet. Gale Watch is in effect.

Monday...Gales continue. Storm force winds possible. Seas around 10
feet will diminish with time to 7-9 feet. Gale Watch is in
effect.

Tuesday...SCA criteria possible; seas may linger around 5 feet.

Wednesday...No marine headlines expected.

&&

.HYDROLOGY...
After collaborating with surrounding offices, the MARFC, and WPC,
we've decided to issue a Flood Watch late Sunday and through the day
on Monday. Yes, we're talking about a 5th and 6th period Watch, but
confidence is ramping up that the region will see rainfall between
2 and 3 inches.

Putting things into perspective, this isn't going to be Ida or an
event with vast widespread impacts, but it could still be an event
that causes a variety of flooding types.

Here's how we see it playing out using the current QPF. Poor
drainage, urban, small stream, and even isolated flash flooding will
commence later on Sunday. It's to our benefit that the ground is
nowhere near frozen, but runoff still becomes more efficient this
time of year when everything that grows becomes dormant. Runoff will
make it to the smaller creeks and streams Sunday night and then to
our rivers beginning on Monday. Portions of the mainstem Passaic
might not flood until Tuesday.

The mainstem Delaware is not expected to reach Flood Stage at any
forecast point. As mentioned, a point or two on the Passaic could
flood on Tuesday. The mainstem Raritan is not forecast to flood at
this time, although Action Stage is possible. Current simulations do
not have any of the mainstem Schuylkill flooding, but with more rain
modeled across PA vs. NJ, I would continue to monitor. So outside of
our mainstems, we'll need to watch our forecast points across SE PA,
and points N and W of the mainstem Passaic. Even places like
Minisink Hills and Shoemakers could see good in-bank rises if the
3 inches of rainfall comes to fruition across the southern Poconos.

So with the possibility of poor drainage, urban, small stream,
flash, river flooding, and flooding along the back bays (due to poor
drainage), we decided to issue a Flood Watch for the entire HSA. We
want to get the message out before everyone leaves for the day and
goes home to relax a bit this weekend.
