AREA FORECAST DISCUSSION
National Weather Service Mount Holly NJ
1235 PM EST Thu Dec 5 2024
Weather Synopsis:
Deepening low pressure will track to our north through today as
a strong cold front sweeps across our area this morning. Cold
and dry high pressure will then build to our west on Friday and
remain situated to our south through the weekend. Several low
pressure systems then look to take aim at the area through the
middle of next week.
Near Term:
THROUGH TONIGHT -
As of 1220pm... High res guidance suggests additional rounds of
snow squalls may be possible through early this afternoon
across northeastern PA, including the Pocono Plateau, and
northwestern NJ, mainly for the higher elevations.
Previous discussion...In the wake of the cold front is when we
expect the winds to really pick up. A Wind Advisory remaining in
effect area wide until 10PM. Generally expect west winds 25 to
35 gusting 45 up to 55 mph with the strongest winds occuring
during the late morning through the afternoon timeframe. Some
tree damage along with scattered power outages will be possible.
Expect rain/snow showers to wind down behind the front except
over the southern Poconos where there will be a continuing
chance for snow showers and snow squalls through the early
afternoon with additional lighter snow showers later in the day.
In terms of any snow accumulation, a dusting up to a half inch
or so will be possible for most areas N/W of the urban corridor
with upwards of 1 to 3 inches possible over the southern
Poconos. Near and south/east of the I-95 corridor, any snow
accumulation should be limited to a patchy light coating on
grassy surfaces, if any at all. Following early morning highs
generally ranging from the mid 30s to low 40s, temperatures will
actually start to fall through the late morning and afternoon
due to the strong cold advection in the wake of the cold front.
By sunset, generally expect temperatures in the low to mid 30s
with it feeling a good 10 degrees colder than this due to the
wind chill.
For tonight, deep low pressure will be moving away from the
area as it moves north and east through Atlantic Canada while
high pressure builds south and east into the Ohio Valley. The
loss of daytime heating will help some to reduce the wind/wind
gusts however the pressure gradient will remain fairly strong so
this will keep winds brisk right through much of the night. By
the overnight, WNW winds should generally be around 15 mph with
still some gusts of 20 to 30 mph. This will help keep
temperatures warmer than they otherwise would have been despite
the very cold airmass continuing to advect in (850 mph
temperatures below -10C!). By Friday morning, generally expect
lows in the mid to upper 20s except upper teens to low 20s over
the southern Poconos and NW NJ.
Short Term:
FRIDAY THROUGH SATURDAY -
Skies will be mostly clear and conditions will be dry for the
majority of the area, except for the Poconos which may have some
lingering cloud cover and a chance for snow showers. Any
additional accumulation will be insignificant, however.
For Friday and Saturday, high pressure over the Mississippi
River Valley will slowly begin to translate east toward the
Southeast US. We`ll likely have one more breezy day though on
Friday as the pressure gradient will remain elevated across the
Mid-Atlantic. Wind gusts are expected to be in the 30-40 mph
range as model soundings suggest that we`ll mix up to around
850mb yet again. Fortunately by Friday night, the pressure
gradient will weaken, so winds will be more tame into Saturday.
Otherwise, Friday into Saturday will feature mostly clear skies
except for a few passing clouds on Friday night. It is possible
some lake enhanced convective snow showers to stream into the
Poconos on Friday night as some shortwave energy passes by, but
the RH in the DGZ air may be too dry for much in the way of ice
crystal development, so I`ve stayed with the previous forecast
and left any such showers out of the forecast at this time.
Long Term:
SATURDAY NIGHT THROUGH WEDNESDAY -
High pressure off to our south will then control our weather
through Sunday night as the weather pattern begins to moderate.
Fair weather conditions are anticipated as warm air advection
brings temperatures back to seasonable levels.
The next system that will bring active weather to the region
should be in the early to middle portions of next week as
forecast guidance suggests that a digging upper level trough
will bring precip to the region. The upper level through should
start with another surface system that is poised to cut up
through the Great Lakes region on Monday with a trailing cold
front approaching from the west. This will likely bring periods
of light to moderate rain to the region beginning late on
Monday.
Beyond Monday, model guidance remains fairly diverse in the
potential solution. The majority of ensemble guidance suggest
that the front will weaken as it approaches and eventually
stall. Depending on where the front stalls out, will determine
what happens for the middle portion of the week if the front
stalls to the west we`ll see more prolonged periods of rain
however if the front ends up clearing the region and stalls
offshore it will result in wetter conditions toward the coast,
and drier conditions north and west. Either way the consensus of
guidance and ensembles is that warmer temperatures are on the
way back with the 850/925/sfc 0C lines well to our north, so the
precip type will be rain.
