Area Forecast Discussion
National Weather Service Mount Holly NJ
105 PM EDT Sun Apr 26 2026

.WHAT HAS CHANGED...
Aviation section updated.

&&

.KEY MESSAGES...
1. Mainly cloudy today, but drying out as high pressure builds
into the region into tonight. Below normal temperatures will
persist. Some areas of frost development forecast tonight for
portions of New Jersey and eastern Pennsylvania.

2. Additional chances for much-needed rain arrive during the
middle of next week.

&&

.DISCUSSION...
KEY MESSAGE 1...Mainly cloudy today, but drying out as high
pressure builds into the region into tonight. Below normal
temperatures will persist. Some areas of frost development
forecast tonight for portions of New Jersey and eastern
Pennsylvania.

Canadian high pressure will build into the region through
tonight as low pressure that brought the weekend rain departs
out to sea. Dry air will be slow to filter in through the day,
so low stratus will persist much of the daytime hours. The
stratus should begin to scatter out and dissipate from north to
south during the afternoon to early evening hours. So while
it'll be a cloudy day overall, most areas outside of far
southern New Jersey and Delmarva should see at least a couple
hours of sun before sunset this evening.

A northeast breeze will persist today as well, generally around
10-15 mph, strongest near the coast where some gusts near 25-30
mph will remain possible. The cloudy skies will keep
temperatures from warming up too much, so temperatures will
remain below normal with highs mainly in the 50s. Northern NJ
and eastern PA will make a run at 60 degrees though, as skies
clearing earlier in the afternoon there should yield more
substantial warming before the sunlight wanes. Highs closer to
50 degrees along the coast, where some drizzle may linger during
the morning.

As skies quickly clear into the night, radiational cooling will
take hold. Winds should become light, favoring a northerly
direction around 5 mph or less. Lows will range from the mid 30s
to low 40s for most areas. Sheltered valleys of northwestern
New Jersey and eastern Pennsylvania should be on the cooler side
of this range, with the surface high in the vicinity. Thus,
some areas of frost are likely to develop. A Frost Advisory was
issued to highlight this threat. Farther south into interior
southern NJ and the outer Philly suburbs in PA, lows in the mid
to upper 30s could produce some patchy frost, but thinking
coverage and temperatures will be a little too marginal to
warrant an advisory at the moment. Will keep an eye on this
though.

KEY MESSAGE 2...Additional chances for much-needed rain arrive
during the middle of next week.

A brief period of high pressure on Monday. A weak frontal
boundary then approaches the region late Tuesday, bringing a
chance for light rain. This frontal boundary will largely wash
out across the region early Wednesday before another stronger
low arrives late Wednesday into early Thursday that could bring
more widespread showers and perhaps an isolated thunderstorm
across the region.

.MARINE...
A Gale Warning is in effect for coastal waters from Manasquan
Inlet NJ south to Fenwick Island DE, out to 60 NM as winds
increase during the daytime hours today, ending at 8 PM this
evening. The Small Craft Advisory for the Delaware Bay remains
in effect through 8 PM as well due to winds in excess of 25
knots. The SCA for coastal waters north of Manasquan Inlet out
to 20 NM remains in effect through today to 6 AM Monday, as
seas will remain elevated overnight even as winds decrease.
Another, SCA will be needed for areas within the Gale Warning as
seas remain elevated in that area as well.

In addition to SCA and Gale conditions, visibility restrictions
are also expected for all marine areas in rain and fog through
this morning.

Outlook...

Monday through Monday night...SCA conditions will linger
through Monday with NE winds gusting near 25 kts and seas at 5-7
feet. Winds diminish below SCA criteria Monday night, but seas
will remain elevated.

Tuesday through Thursday...SCA conditions possible due to
elevated seas around 5 feet.
