What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Nov 28, 6:12 AM EST, 1 hour 27 minutes earlier.

Area forecast discussion, Nov 28, 6:12 AM EST, 1 hour 27 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
612 AM EST Tue Nov 28 2023

.SYNOPSIS...
Colder air will continue to drape over the region through today and
tonight. Surface high pressure will build in today and hold a firm
grasp over the region through Thursday. Low pressure approaches
Friday with the potential for a stronger area of low pressure
affecting the area by early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
For today, it will feel more like January as strong cold air
advection continues. 850 mb temperatures will drop into the -10
to - 14 C range, which will result in surface temperatures only
getting into the mid to upper 30s. It will feel even colder than
that as deep mixing will allow for gusty winds to get down to
the surface. Gusts will peak in the 30-35 MPH range later this
afternoon, though it wouldn't be a surprise to see some 40 MPH
gusts as 30-35 kt winds are not far off the surface. The
resulting wind chills due to the cold and blustery conditions
will be in the 20s. Skies will be partly to mostly cloudy with a
stratocumulus deck increasing in coverage as the morning goes
on.

Perhaps the more intriguing portion of the forecast will be for
later today and the potential for a few snow showers. A trough axis
will pass later today, with modest to strong positive vorticity
advection out ahead of it. This will provide sufficient lift to
support some lake effect streamers to make it into the western
portion of our area. PoPs were expanded with this update as certain
parameters show relatively favorable conditions for some lake-effect
streamers to make it as far west as western New Jersey.

Taking a look at the overnight guidance, moisture will work its way
into the lower and mid-levels with RH values within the 0-2 km
portion of the atmosphere getting above 70%, primarily west of
Philadelphia. Low level lapse rates will be quite high as well,
indicating an unstable atmosphere, with some model soundings showing
low-level lapse rates around 9 C/km. 850-700 mb lapse rates look to
hover around 8 C/km. Model soundings also show marginal CAPE values
within the DGZ, with the highest instability again north and west of
the Philly metro. Finally, progged snow squall parameter values
hover around 1 to 4 (anything above 1 represents favorable
conditions for squalls). The highest values (3 to 4) are within the
Pocono plateau with lower values (around/greater than 1) are within
the Lehigh Valley. The main limiting factor though will be the
amount of dry air within the low-levels. Dewpoint depressions at the
surface will be around 15-20F during the afternoon. This should
limit the threat for squalls/heavy snow, and result in a more snow
shower setup. Not everyone will see snow, and PoPs hover around 30-
50% west of the Fall Line, but for those that do, accumulations
should be a few tenths at most, so nothing overall significant. If a
heavier band can overcome the dry air however, values up to an inch
are possible. This is most likely to occur in the southern Poconos.
The HREF has around a 40-60% chance of measurable snowfall for the
Lehigh Valley, Pocono Plateau, and NW NJ. While areas within the I-
95 corridor and parts of western NJ can see some flakes, not
expecting any measurable accumulations.

For tonight, skies will clear out as the stratocumulus deck
scatters. Winds will diminish with the nighttime inversion trying to
set up, but some spots may not fully decouple. OVernight lows will
be in the low to mid 20s for the most part, with more
rural/sheltered areas and higher elevations getting into the upper
teens. A very chilly night overall.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
Quiet weather will dominate for the short term period due to high
pressure nearby to our south. After a cold start, temperatures will
still struggle to recover for Wednesday as we remain in a cold
airmass for this time of year. The day should feature mainly sunny
skies over Delmarva and southern NJ with some periods mid and high
clouds across eastern PA into NW NJ as this area will be near the
southern fringe of a system passing by well to our north. Highs look
to range mainly from the mid 30s to low 40s except only around 30
over the Pocono Plateau.

Mainly clear skies with light winds for Wednesday night will lead to
another night of good radiational cooling. However with the winds
turning southwest, it likely won't be quite as cold as Tuesday
night. Expect lows mostly in the mid 20s except low 20s over the
Poconos and upper 20s to around 30 near the coast and the Delaware
Bay.

For Thursday, an area of low pressure will lift north and east
through northern Ontario and Quebec helping strengthen the warm
advection pattern along the east coast as high pressure also moves
off the coast into the Atlantic. This will result in temperatures
moderating back to the upper 40s to low 50s for highs as SW flow
persists. The day should overall feature partly to mostly sunny
skies.

High pressure will continue lose its influence over the area for
Thursday night as it continues moving east into the Atlantic.
Meanwhile the next low pressure system will be organizing itself
near Missouri with a cloud deck extending well north and east of the
low's center and spreading increasing clouds into the area through
the night. This will help lead to a relatively milder night with
lows mostly in the mid 30s except low 30s over the Lehigh Valley and
the southern Poconos and upper 30s to around 40 near the coast.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
The weather pattern continues to trend milder but more unsettled for
the long term period as a long wave trough sets up near the central
CONUS putting the east coast in a broad SW flow. An initial quick
hitting system looks to move through with mostly just some rainfall
for Friday into Friday night as an upper level wave moves quickly
through the flow. The exception will be across the southern Poconos
where there is a slight chance of a very brief period of snow or
mixed precip at the onset if the precip moves in early enough in the
day. It's not a great set up for snow though, even in the southern
Poconos, as high pressure will out over the Atlantic, not to the
north of the area. This will result in a continuing southerly flow
as opposed to a cold air damming set up. Otherwise, it does not look
to be a particularly impactful system for Friday, other than making
for a wet end to the week, as rainfall amounts should be a half inch
or less.

The forecast gets a bit more uncertain heading into the weekend and
beyond but looking at the big picture, another weak impulse looks to
move through around about Saturday or Saturday night however there
won't be much moisture with this. For this reason, we keep the
forecast dry for Saturday but it should be mostly cloudy. A stronger
area of low pressure driven by the main upper level trough axis as
it swings east looks to eventually form and affect the area
beginning either by late Sunday or Monday. The timing details remain
uncertain at this time as there are differences between our forecast
models but all currently show a stronger low eventually affecting
the east coast by roughly around the Sunday / Monday timeframe.
Precipitation amounts could be more significant with this system but
it should again remain warm enough for it to be a mainly rain event.
Given the uncertainty in the forecast, we again stayed close to the
NBM with this update.
