Area Forecast Discussion
National Weather Service Mount Holly NJ
116 AM EDT Sun Oct 27 2024

.SYNOPSIS...
High pressure will build overhead today. The high moves
offshore on Monday, but will remain within the vicinity of the
Mid-Atlantic coast through Thursday. A cold front will cross
through the region on Friday with high pressure returning for
next weekend.

&&

.NEAR TERM /THROUGH MONDAY/...
Early this morning, high pressure remains centered over
northwestern Pennsylvania, with enough of a gradient to keep the
winds stirred up and radiational cooling limited. We're still
chilly, with some 30s and widespread 40s, but not the really
cold night we're expecting tonight. Passing uppper trough/jet
streak will spread some mid-high clouds across the area,
especiallly south of Philadelphia, but all-in-all, a pretty
decent Sunday is on tap with much lighter winds than yesterday
and temps rebounding to the vicinity of 60, which side of that
mostly depending on whether you are north or south of
Philadelphia.

High pressure will shift east and be almost directly overhead
tonight, and with the upper trough starting to lift out, we
should have clear skies. Combined with sub-freezing dew points,
and we should be primed for a widespread freeze across much of
the region, so current plan is to upgrade the freeze watch to a
warning for most of the area and add some frost advisorys for
the peripheries. This could potentially end the growing season
for much of the region...though, given our ever increasingly
severe drought, there really isn't much growing unless its
irrigated.

Monday the high shifts off shore and we start to get some warm-
advection aloft, which may lead to some high cirrus in the
afternoon. Overall, another pretty decent day, with highs rising
into the low-mid 60s for most with continued light winds.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
An upper level ridge will begin to creep closer to our area
through the short term. The surface high will slide offshore on
Monday, but will remain situated off the Mid-Atlantic coast
through mid-week. As the high shifts off the coast, return flow
will gradually shift from north to south. This will result in
warm air advection filtering into our region with temperatures
gradually warming through the period.

All in all, conditions across the region will remain tranquil
with mostly clear skies through the period. May see some clouds
filter into northern areas on Tuesday as a disturbance passes
well to our north, but no precipitation is expected. In terms of
temperatures, looking at highs in the upper 50s to mid 60s on
Monday warming into the mid 60s to around 70 degrees on Tuesday.
Lows Monday night will remain on the cooler side, mostly in the
30s/40s with 50s along the coast.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Overall, little changes were made to the long term forecast as
temperatures as much as 10-15 degrees above normal are expected
through Thursday before returning closer to average by next
weekend.

As mentioned in the short term, high pressure will be settled
off the Mid-Atlantic coast with warm air advection flowing into
our region through Thursday. Temperatures will gradually step up
each day with highs in the 70s to near 80 degrees for Wednesday
and especially on Thursday. So, it will be definitely be one of
the warmer Halloweens in recent memory. Too early to tell if we
may approach records, but may be in the realm of possibility.

Otherwise, a cold front is anticipated to approach from the
north and west on Thursday night and cross through our area on
Friday. Some showers should be accompanied with the frontal
passage this go around, with the greatest potential in the
Poconos where forcing is greater. Overall, have a 20-40% chance
of showers during this timeframe. Behind the front, high
pressure will build back in from the Midwest by next weekend. So
in the grand scheme of things, the next best chance for some
much needed rainfall is with the front late in the week,
otherwise, no relief to the prolonged dry stretch is in sight.

&&

.AVIATION /05Z SUNDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas...

Thru 12Z...VFR. North/northwest winds around 5-10 kt. High
confidence.

Sunday...VFR.North/northwest winds around 5-10 kts. High
confidence.

Sunday night...VFR. Winds becoming light/variable. High
confidence.

Monday...VFR. Winds becoming E 5-10 kts. High confidence.

Outlook...

Monday night through Thursday...VFR. No significant weather
expected.

&&

.MARINE...
A Small Craft Advisory will expire 6 AM this morning for wind
gusts around 25 kt and seas 3 to 5 feet. Winds and seas are
diminishing.

Today through Monday...sub-SCA conditions expected with
west/northwest winds around 10-15 kt and 2 to 4 foot seas early
today, winds diminishing to 5-10 kts and seas 1-3 feet tonight,
then winds shifting easterly Monday but remaining 5-10 kts.

Outlook...

Monday night through Wednesday night...Fair weather. No marine
headlines expected.

Thursday...SCA conditions possible with wind gusts up to 25 kt and
seas around 5 feet.

&&

.FIRE WEATHER...
For today, while minimum RH values will be around 20-30%, winds
will be around 5-10 mph, limiting the risk for the spread of
wildfire. However, given how dry its been, there is still some
threat and in collaboration with our state fire weather
partners, a Special Weather Statement has been issued for today.

For Monday, minimum RH values will be around 25-35% with winds
around 5-10 mph. Regardless, given dry vegetation, an elevated
risk of fire spread will remain.

Burn restrictions may still be in place given the very dry
conditions and lack of any recent rainfall. Refer to your state's
forest fire management agency for more information.
