Area Forecast Discussion
National Weather Service Mount Holly NJ
546 AM EST Mon Dec 22 2025

.SYNOPSIS...
Canadian high pressure will build into the region through
today. High pressure will move offshore tonight, then a clipper
system will impact the region early Tuesday with a warm front
lifting north. A cold front will push offshore Tuesday night,
followed by weak high pressure building on Wednesday. Another
weak clipper may impact the area with light precipitation on
Christmas Day, then a stronger system looks to impact the region
on Friday. Unsettled weather may persist into the weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Today: High pressure across the region today will slowly move
east by evening. Sunny skies are expected today with seasonably
cool temps expected. Highs will top out in the upper 30s for
North NJ, the Lehigh Valley and the southern Poconos. Other
areas will reach the low 40s. Winds will be West to Northwest at
5 to 10 mph this morning then Southwest around 10 mph for the
afternoon.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
A period of light snow, and potentially some wintry mix and
rain are anticipated to impact portions of the region late
tonight through Tuesday morning. There have been no significant
changes to the forecast for this system. Thereafter,
temperatures will remain relatively mild and seasonable with
breezy conditions expected for Christmas Eve (Wednesday).

Cold and dry Canadian high pressure will shift gradually
offshore into tonight. The cold and dry Canadian airmass will
remain in place, at least initially. We should see radiational
cooling during the evening, with temperatures dropping into the
mid 20s to low 30s before thicker clouds start moving in from
the approaching system. Warm advection will increase aloft
overnight as a mid level wave, clipper-like system approaches.
With the absence of any strong surface pressure features, low
level wind fields, including surface winds, will remain quite
light. So the warm advection will be very weak, and the cold,
dry antecedent surface airmass should remain anchored in place
through much of the overnight period as mid level dynamics begin
to produce some light precipitation despite a warm front trying
to nudge its way in. Even if surface temperatures increase a
few degrees overnight, wetbulb temperatures will remain below
freezing across much of interior New Jersey and Pennsylvania
thanks to dewpoints near 20 degrees.

Guidance remains in decent consensus that we will see at least
a few hundredths of QPF as far south as the Philly metro after
midnight tonight into Tuesday morning, and as much as 0.1-0.25"
near and especially north of I-78. The CAMs and hi resolution
guidance seems a little low given the mid level dynamics at
play, so not totally buying their drier solutions (compared to
synoptic models) just yet. Near and north of I-78, PoPs remain
in the 70-80% range. South of I- 78, PoPs are in the 40-60%
range. It still appears that precip will begin before dawn
Tuesday for many areas, as this is when the main push of warm
advection and mid level dynamics increase. One limiting factor
is that, while there will be sufficient moisture and forcing for
precip, the precip will have to overcome the initially dry air
in the low levels. This will work to limit QPF and snowfall
amounts farther south into the Philly metro, where forcing and
moisture lessens the farther south you go. THus, there is still
a degree of uncertainty on how far south any measurable snowfall
will occur into the Philly metro, southern New Jersey, and
northern Delaware. The warm advection nature of this system
should also yield poor snow ratios. We are forecasting snow
ratios near 5:1 to 10:1 at best.

As for forecast snowfall accumulations, generally expecting
less than 1" for areas near and south of I-78 down into the
Philly metro and adjacent areas of interior southern New Jersey,
far northern Delaware, and the northern Jersey Shore (LBI and
north). For the I- 95 corridor and Philly metro, thinking a full
1" would be a reasonable worst case scenario we could see from
this system. Areas north of the I-78 corridor have the best
chances of receiving a plowable 1-2" of snowfall. The usual
higher elevations of northern New Jersey and eastern
Pennsylvania could see isolated amounts as much as 3-4" of snow
in a reasonable worst case scenario, but the probability of this
is low at the moment (~20%), and will be conditional on exactly
how much QPF we can squeeze out of this weak system.

There also remains some potential for a light glaze of ice,
mainly for the southern Poconos, as precipitation could change
to rain there before temperatures warm above freezing.

While we do have sufficient forcing and moisture for snow, the
dynamics at play are vastly weaker than last weekend's snow
storm. With that said, snow falling Tuesday morning could
certainly cause travel issues and slippery/icy roads despite the
light snowfall amounts. In any case, this is still not expected
to be a significant snow event for our area. A Winter Weather
Advisory could be warranted for Carbon and Monroe Counties in
Pennsylvania if confidence increases enough for snowfall amounts
nearing 3" and/or a light glaze of ice to occur in these areas.

Confidence and chances for precip are lower (30-50%) south of
the Philly metro into far southern New Jersey and Delmarva. This
region will have much less moisture and forcing, and thus lower
measurable precip if any. It will also be warmer here, with
wetbulb temperatures mainly above freezing by the time any
greater precip chances arrive. So any snow that does fall is
most likely to be "white rain" (snow melting as it falls).

Any lingering precipitation will be ending by noon or so on
Tuesday, then temperatures should start warming up by a few
degrees. Based on the latest deterministic guidance, our current
high temperature forecast for Tuesday could still be a bit too
high, especially for any areas that experience snow cover north
of the Philly metro. Skies should remain mostly cloudy for the
remainder of the day, and warm advection gradient winds will not
be very strong at all. Long story short, a low confidence high
temperature forecast for Tuesday, but most areas should
eventually warm above freezing into the afternoon, which should
help to start melting away our light snowfall accumulations and
improve lousy road conditions for the holiday travelers.

Low temperatures Tuesday night into Wednesday morning are
mostly in the mid to upper 30s (above freezing) south of I-78,
and close to 30 degrees north of there. So any icy roads from
refreezing snow melt or slushy should be confined to untreated
roads north of I-78. Winds will also increase Tuesday night as a
cold front pushes offshore, which should help to dry things out
a bit more too.

Weak high pressure will build into the area from the Great
Lakes region Christmas Eve and center itself over the area
Christmas Eve night into Christmas morning. We look to stay out
of the strong cold advection this time around, so temperatures
should remain close to normal for late December. However, it'll
be a bit breezy during the day with NW winds gusting near 30 mph
possible, then becoming light to calm overnight. High
temperatures will be mainly in the 40s on Christmas Eve, and
lows mainly in the mid 20s to mid 30s for Santa during Christmas
Eve night. Mostly sunny skies for Christmas Eve, then
increasing clouds overnight.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Christmas Day should be a decent day overall with no
significant weather, but a weak clipper system passing through
could bring some brief light rain or sprinkles (flurries
possible up north) in the morning. PoPs remain around 20-40%.
Otherwise, it'll be mostly cloudy to overcast with seasonable
temperatures (highs in the upper 30s and 40s). Christmas night
will remain cloudy, but this will keep temperatures relatively
mild with lows in the mid 30s to low 40s.

Beyond Christmas Day, forecast uncertainty becomes very high.
Guidance indicates there will be a high over eastern or
southeastern Canada with low pressure moving eastward across the
Great Lakes and toward the Northeast or Mid Atlantic. This
setup will likely bring precipitation to our area. The 00Z suite
of guidance had a significant change in course, indicating a
much stronger high and weaker, more suppressed low. This
solution would introduce potential for wintry precip for our
region and much colder temperatures, quite the change from
widespread 50s and rain from before. The shift in guidance was
consistent between different models. GFS, ECMWF, and CMC all
showing this much colder, wintry solution now, however given
this *very* recent change in course, have stuck with NBM for now
until there is more consistency in a colder, more wintry
solution. Precipitation is still likely, with 50-80% PoPs,
however we could be dealing with all rain, a significant wintry
system, or anything in between. Remain alert for changes to the
forecast for the Friday timeframe.

The weekend forecast is also highly uncertain, but could remain
unsettled. Stuck with NBM.
