Area Forecast Discussion
National Weather Service Mount Holly NJ
241 PM EST Sun Feb 16 2025
.SYNOPSIS...
Low pressure lifts through the Northeast early this evening,
and this will drag a cold front through the region tonight. High
pressure builds in from the west for the first half of the new
week. Coastal low pressure may affect the area Wednesday night
through Thursday. High pressure returns to close out the new
week.
&&
.NEAR TERM /THROUGH MONDAY/...
A strong storm system will continue to impact the region today
into Monday with the main hazard associated with the storm being
the strong, damaging winds that are still expected in the wake
of its cold front.
As of 145 PM this afternoon, a large and deepening area of low
pressure was centered near central PA. A warm front extends east
from the low across SE PA into southern NJ with a cold front
extending southward into portions of Virginia and the Carolinas.
There is a strong temperature gradient across the area in
association with the warm front as it's separating temperatures
in the 50s and 60s south of the front vs. 30s and 40s north of
the front. In fact it's still in the low 30s over Mount Pocono!
We've had an initial area of some heavy showers move through and
this will be moving off the coast within the next hour or two.
Most areas should then see a lull before the cold front sweeps
through from west to east during the latter half of the
afternoon (roughly around 3 PM for our western zones, clearing
the coast by around 6 PM). Some additional showers will be
possible as this occurs. Otherwise, the main focus will be
shifting to the very strong winds that are still expected with a
Wind Warning in effect area wide. Winds have have been a bit
slow to come up so far due to the slower than expected progress
of the warm front northward but we have started to see some
southerly wind gusts of 30 to 40+ mph over portions of Delmarva
as well as southern and coastal NJ south of the warm front in
the warm sector.
In the wake of the strong cold front passing through around 3
PM to 6 PM, temperatures will plummet with wind chills in the
teens by late tonight. The main concern for late this afternoon
and evening through Monday will be the strong to damaging west
to northwest winds developing.
The synoptic pattern is very favorable for high winds. Surface
pressure rises exceeding 1 mb/hour, perhaps as much as 8 mb
within just 3 hours, and very strong cold advection will support
efficient boundary layer mixing immediately in the wake of the
frontal passage and overnight tonight into Monday. A consensus
of deterministic BUFKIT profiles and HREF ensemble profiles
indicate boundary layer mixing through the 925 mb layer, and
perhaps as high as the 850 mb layer at times. Wind speeds at
these levels around 35-50 kts should serve as a good proxy for
wind gusts given the efficient mixing. 925 mb winds likely
serving as a more prevailing wind gust proxy, with 850 mb winds
serving as a peak gust proxy. This will translate to frequent
westerly gusts in the 45-60 mph range across the entire area,
with the strongest winds most likely occurring across the higher
elevations and near the coasts. The peak gusts of the event
near 50-60 mph are likely to occur immediately in the wake of
the frontal passage. This will be when the aforementioned
boundary layer wind speeds are strongest and surface pressure
rises are sharpest. Thereafter, westerly gusts of 40-55 mph will
likely prevail for much of tonight through at least the first
half of Monday before beginning to subside. The High Wind
Warning remains in effect for an extended period of impacts from
high winds.
While the peak gusts upwards of 60 mph are not expected to
prevail during the entire warning period, wet soils combined
with the high winds could result in extensive tree damage
through the event. Additionally, the strong winds will usher in
much colder air, with temperatures in the 20s and 30s and wind
chills in the teens. We are most concerned about the potential
for power outages combined with the cold, which could exacerbate
the impacts of this high wind event for folks that lose power
with it being so cold out. Please take this event seriously!
As previously mentioned, low temperatures tonight into Monday
morning will be mainly in the 20s to near 30 degrees with wind
chills dropping into the teens. Temperatures will struggle to
climb from morning minimums on Monday, with highs generally
ranging from the 20s north to the 30s south. But with the wind
chill, it will feel a good 10 to 15 degrees colder than the
actual temperatures.
&&
.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
Arctic high pressure builds in from the west and an arctic
airmass spreads into the region. Temperatures will run some 10
to 15 degrees below the seasonal averages for this time of the
year. 850 mb temperatures Monday night and Tuesday night will be
from -18C to -20C over the southern Poconos, far northwest New
Jersey, and the Lehigh Valley to -11C to -17C for most of New
Jersey and southeast Pennsylvania to -8C to -10C over Delmarva.
This will result in low temperatures Monday night ranging from
the single digits in the southern Poconos and far northwest New
Jersey to the teens for most of New Jersey and southeast New
Jersey and in the low 20s in Delmarva. A westerly breeze of 15
to 20 mph will yield min wind chill values as low as -15 in the
higher elevations of the southern Poconos to 0 to -5 in most of
northern New Jersey and southeast Pennsylvania, and 5 to 10 in
southern New Jersey and Delmarva. Winds may be a bit lighter
Tuesday night, but air temperatures may be a degree or 2 colder,
resulting in similar wind chills Tuesday night compared to
Monday night.
Mostly sunny and cold on Tuesday with highs generally in the
20s to low 30s, though in the teens in the southern Poconos.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
All eyes continue to be on the potential coastal storm gearing
up to affect the Mid-Atlantic and Northeast during the mid-week
period. High pressure over the area slides offshore on
Wednesday. Meanwhile, a closed H5 low moves into the Northern
Plains and upper Midwest, and a trough will extend down from
that low and into the Gulf Coast states. Surface low pressure
will develop out ahead of that trough on Wednesday, and that low
lifts towards the Mid-Atlantic.
There still is plenty of time for the finer details to develop,
and there is still a good deal of uncertainty among the models.
12Z/16 ECMWF has significant snow accumulation over most of
southern New Jersey and Delmarva, while the 12Z/16 CMC is almost
a complete miss. 12Z/16 GFS kind of splits the difference.
12Z/16 guidance seems to have sped up the timing of the low,
where the impacts would be more Wednesday night, with the low
departing Thursday morning. Still quite cold with highs in the
20s to around 30 for both Wednesday and Thursday, and lows will
be in the teens and low 20s. The focus for the highest snow
accumulations will be over Delmarva and the coastal plain of New
Jersey. Models still could shift back farther to the west.
The probabilities from the National Blend of Models (NBM) are
coming into focus. The 13Z/16 indicates for the 48 hour period
from 7 am Wednesday through 7 am Friday: 20 to 40 percent
probability for more than 4 inches of snow north and west of the
I-95 corridor; a 40 to 60 percent probability for more than 4
inches of snow across the I-95 corridor; a 60 to 80 percent
probability for more than 4 inches of snow for the eastern
shores of Maryland, Delaware, and the coastal plain of New
Jersey. For the 48 hour period from 7 am Wednesday through 7 am
Friday: 10 to 20 percent probability for more than 8 inches of
snow north and west of the I-95 corridor; a 30 to 40 percent
probability for more than 8 inches of snow across the I-95
corridor; a 40 to 60 percent probability for more than 8 inches
of snow for the eastern shores of Maryland, Delaware, and the
coastal plain of New Jersey. For the 48 hour period from 7 am
Wednesday through 7 am Friday: 10 percent probability for more
than 12 inches of snow north and west of the I-95 corridor; a 20
to 30 percent probability for more than 12 inches of snow
across the I-95 corridor; a 30 to 40 percent probability for
more than 12 inches of snow for the eastern shores of Maryland,
Delaware, and the coastal plain of New Jersey.
High pressure builds in from the west behind the departing
storm and will eventually build over the area by next weekend.
Temperatures will still run 10 degrees below the seasonal
averages during this time with highs in the mid to upper 30s and
lows in the teens and low 20s.

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
This afternoon...IFR or lower in low clouds, mist, and showers
until a cold front moves through west to east...this will occur
an hour or two either side of 21z. Following the passage of the
front, winds shift to strong westerly at 20 to 30 gusting 40 to
50 knots. This will bring improving visbys and cigs initially
back up to MVFR right after the front passes and then to VFR for
most sites by early this evening.
Tonight...VFR. Westerly winds should decrease slightly, but
gusts near or above 40 kt still possible.
Monday...VFR. Westerly winds gusting near 40kt especially early
in the day.
Outlook...
Monday night through Tuesday night...VFR.
Wednesday through Thursday...Sub-VFR likely in SN. Improving
conditions Thursday afternoon.
Thursday night through Friday...VFR.
&&
.MARINE...
A strong cold front will pass quickly offshore around 4 PM to 6
PM. The front will bring and abrupt shift in wind direction to
westerly. Storm force gusts near 50 kts are anticipated for a
few hours following the cold front, which has prompted the
upgrade to a Storm Warning for the period. Following the Storm
Warning, A Gale Warning will be needed through Monday. Seas 5-9
feet tonight into Monday.
Low water is possible near the times of low tide beginning
tonight through Tuesday.
Outlook...
Monday night through Tuesday night...Lingering gales possible
Monday night, otherwise, SCA conditions. There is a chance for
freezing spray due to the strong winds and cold air temperatures
spreading over the waters.
Wednesday through Wednesday night...Sub-SCA conditions. VSBY
restrictions in SN starting Wedensday afternoon.
Thursday through Thursday night...SCA conditions. VSBY
restrictions in SN through Thursday afternoon.
Friday...Lingering SCA conditions possible into Friday
afternoon.
