Area Forecast Discussion
National Weather Service Mount Holly NJ
614 AM EST Sun Feb 8 2026

.WHAT HAS CHANGED...
The Wind Advisory for Carbon and Monroe counties is no longer in
effect.

The Extreme Cold Warning for Carbon and Monroe counties is now in
effect until 10 AM Monday. Cold Weather Advisories are now in
effect for most of New Jersey, southeast Pennsylvania, Delaware and
the eastern shore of Maryland from Noon today through Monday
morning.

&&

.KEY MESSAGES...
1. Dangerous wind chill values will continue through Monday morning.

2. Temperatures moderating to right around average for the middle of
this week. A warm front may bring some light wintry precipitation to
parts of the region later Tuesday.

&&

.DISCUSSION...
KEY MESSAGE 1...Dangerous wind chill values will continue through
Monday morning.

Northwest winds will continue to range from 15 to 20 mph with
25 to 35 mph gusts through late this afternoon. Winds will
diminish fairly quickly this evening, and then will range from 5
to 10 mph tonight.

Due to how cold it will continue to be, winds remain elevated
enough to result in dangerous wind chill values.

Broad Arctic high pressure centered over the Great Lakes and
Ohio Valley slowly builds east today, then will be overhead
tonight before moving offshore on Monday. Highs today will be in
the single digits in the southern Poconos and the teens
elsewhere. With the winds, wind chills today will mostly be in
the single digits to as low as -10. Tonight, lows will be in the
single digits throughout with wind chill values as low as -20
in the southern Poconos and as low as -10 to -15 elsewhere.

As a result, the Extreme Cold Warning for Carbon and Monroe
counties has been extended through Monday morning and Cold
Weather Advisories are now in effect for the rest of the area
from noon today through 10 am Monday.

Heights aloft begin to rise on Monday, and warm air advection
will be underway. Highs will mostly be in the upper 20s to
around 30.

KEY MESSAGE 2...Temperatures moderating to right around average
for the middle of this week. A warm front may bring some light
wintry precipitation to parts of the region later Tuesday.

As heights build aloft with a ridge slowly migrating east and
arctic surface high pressure shifting off the coast, warm air
advection will be underway and this will translate to
temperatures moderating Tuesday and then to right around average
on Wednesday. This will result in thawing taking place more
each day through at least Wednesday. Low temperatures however
will drop below freezing each night resulting in thaw and
refreeze cycles, with lows Tuesday night looking like the milder
night due to southwest winds ahead of a cold front.

The cold front will cross the region sometime later Wednesday
as low pressure passes to our north. Given the track of the
surface low to our north and this being more of a clipper
system, the main forcing for ascent is just to our north and the
moisture is limited. This results in lower chances for
precipitation. The NBM has some slight chance PoPs (20 percent)
across the far north by later Tuesday with an incoming warm
front, otherwise the PoPs are trending downward. Some 00z
guidance has trended a little stronger though with the
isentropic lift with the warm front later Tuesday, which could
produce some frozen or freezing precipitation especially across
our northern areas. As of now, made no changes to the NBM
guidance. It then turns colder for the second half of the week,
but not to the magnitude of our current arctic outbreak. A storm
may then arrive during the weekend with the potential for some
rain and/or wintry precipitation.

&&

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Today...VFR. NW winds 15 to 20 kt with 25 to 35 kt gusts,
diminishing to 10 to 15 kt with 20 to 25 kt gusts after 21Z.
High confidence.

Tonight...VFR. NW winds 10 to 15 kt with gusts up to 20 kt,
diminishing to 5 to 10 kt after 03Z. High confidence.

Monday...VFR. NW winds 5 to 10 kt. High confidence.

Outlook...

Monday night and Tuesday...VFR ceilings lower.

Wednesday and Thursday...VFR overall. Northwest winds gusts to
around 20 knots possible.

&&

.MARINE...
Northwest winds of 20 to 30 kt with 40 to 45 kt gusts will continue
through this morning, and Gale Warnings and Heavy Freezing Spray
Warnings remain in effect. Winds diminish this afternoon, and Small
Craft Advisories and Freezing Spray Advisories will be needed for
later today and tonight.

Sub-SCA conditions expected on Monday.

Regarding the river/bay ice...Ice continues across area bay
waters and inland estuaries. This includes, but is not limited
to the Delaware estuary. On rivers, the ice has grown in
thickness enough to cause some restrictions in the flow. Per
satellite imagery and ice analysis data, the Delaware River is
mostly ice covered from the entrance to Delaware Bay northward,
or upstream, to at least Washington Crossing.

The most common ways river ice can break up is either through a
thermal or mechanical means. We would like to see temperatures
rise into the 40s for a few days, but that's not expected over
the next few days. Some areas though are forecast to get to
around 40 degrees Wednesday afternoon. Significant rainfall,
producing river rises, can also break up ice but that is not in
the forecast this week.

As a result, ice will continue to expand before it contracts,
especially with this ongoing deep freeze this weekend. For this
week, there may be a pause in the ice growth during the
daylight hours as temperatures warm above freezing, however
temperatures at night will continue to support expansion.

Outlook...

Monday night through Wednesday...No marine headlines are anticipated.

Thursday...A period of near Small Craft Advisory conditions possible.
