Area Forecast Discussion
National Weather Service Mount Holly NJ
1244 AM EDT Wed Oct 16 2024

.SYNOPSIS...
Strong high pressure builds southward from Canada across the Midwest
to the mid-Mississippi Valley into Wednesday. This high slides
eastward and closer to our area Wednesday night and Thursday, then
it settles right over our area Friday and into early next week,
perpetuating our dry spell.

&&

.NEAR TERM /THROUGH TODAY/...
Forecast is running on track, so no significant changes will be
made to the forecast.

High pressure will build southward into the central Plains tonight.
Meanwhile, an upper trough will extend from a closed upper low
over eastern Canada and will build down into the Northeast and
Mid-Atlantic. Shortwave energy will pass through the region
tonight, and the base of the trough will remain over the region.

Clouds may hold on overnight over the Poconos in northwest
flow. Pressure gradient relaxes tonight, and winds will diminish
to 5 to 10 mph. Lows tonight will once again mainly be in the
low to mid 30s, though in the low 40s in Philadelphia and along
the coasts. Once again, patchy frost is possible away from the
urban centers, with more widespread frost likely in the southern
Poconos, Lehigh Valley, and northwestern New Jersey.

High pressure will build eastward on Wednesday to be centered
over the lower Ohio Valley by Wednesday evening. Another mostly
sunny day is expected on Wednesday with temperatures similar to
Tuesday.

&&

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
High pressure ridges in from the west Wednesday night, allowing
for skies to clear and winds to become calm. Temperatures at
night drop into the 30s for many places with patchy to areas of
frost. The extent of the frost will depend on lingering cloud
cover and especially if the wind can completely decouple by
daybreak Thursday for more areas. Some spots in the Poconos into
northwest New Jersey especially may drop just below freezing.

For Thursday, a closed low shifts to our east with time taking
surface low pressure with it. An upper-level ridge then to our west
will shift eastward bringing surface high pressure closer to our
area. Despite the presence of the closed low, the forcing for ascent
is forecast to remain offshore and therefore another dry day is
forecast. The air mass associated with the incoming surface high
results in temperatures continuing to be several degrees below
average with much of the area topping out once again only in the 50s
to near 60 degrees. Temperatures at night drop into the 30s for many
places with patchy to areas of frost. The extent of the frost will
once again depend on if the wind can completely decouple at night.

For Friday, high pressure shifts nearly squarely overhead the Mid
Atlantic and Northeast. Slightly warmer and more seasonable
conditions with highs reaching the mid to upper 60s.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
High pressure with a strong upper level ridge remains in control
over the region. Gradual warming expected each day with afternoon
temperatures returning to the 60s with even some low/mid 70s into
early next week. Temperatures at night will be cool but not as cold
compared to earlier in the week.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Tonight...VFR. W-NW winds 5 to 10 kt.

Wednesday...VFR. NW wind 10 to 15 knots with a few gusts to 20
knots.

Outlook...

Wednesday night through Saturday...VFR. NW winds.

&&

.MARINE...
NW winds 10 to 15 kt tonight and 15 to 20 kt on Wednesday along
with seas 3 to 4 feet. No marine headlines.

Outlook...

Wednesday night and Thursday night...A few 25-knot wind gusts are
possible, especially on the ocean zones.

Friday and Saturday...The conditions are anticipated to be below
Small Craft Advisory criteria.

&&

.FIRE WEATHER...
For Wednesday, MinRH values will continue to be in the 30 to 35
percent range for most of New Jersey, portions of southeast
Pennsylvania, and Delmarva along with northwest winds averaging
10 to 15 mph with 15 to 25 mph gusts. As a result, there will be
the threat for fires to spread quickly.

&&
