Area Forecast Discussion
National Weather Service Mount Holly NJ
146 AM EDT Sun Apr 12 2026

.WHAT HAS CHANGED...
Aviation discussion updated.

Increasing confidence in well above normal temperatures next week
and a legitimate chance for the first 90 degree of 2026 for
Philadelphia.

&&

.KEY MESSAGES...
1. A mainly dry weather pattern continues through the weekend,
continuing an elevated risk for fire spread.

2. Frost possible across portions of southeast Pennsylvania
tonight through early Sunday morning.

3. A significant warm up is expected for the early and middle
part of next week with temperatures anticipated to reach 90F for
the first time this season along portions of the I-95 corridor
on Wednesday and Thursday.

&&

.DISCUSSION...
KEY MESSAGE 1...A mainly dry weather pattern continues through
Sunday, continuing an elevated risk for fire spread.

Conditions will be slightly less favorable (compared to
Saturday) for fire spread during Sunday, but remain marginal
across the region. Minimum RH values around 30-40% with winds
turning more S-SE in the afternoon gusting up to around 20 mph.

KEY MESSAGE 2...Frost possible across portions of southeast
Pennsylvania tonight through early Sunday morning.

With high pressure moving overhead tonight into early Sunday
morning, calm winds and clear skies will give way to the
potential for strong radiational cooling. Overnight lows are
forecast to fall into the low to mid 30s for areas north and
west of the I-95 corridor. Despite a dry airmass in place, dew
point depressions will be sufficient to support the potential
for patchy frost. A Frost Advisory has been issued for Berks,
western Chester, and western Montgomery counties late tonight
into early Sunday morning where the growing season has begun.
For the Lehigh Valley, Poconos, and northern New Jersey, patchy
frost is possible, but the growing season there has not begun
yet.

KEY MESSAGE 3...A significant warm up is expected for the early
and middle part of next week with temperatures anticipated to
reach 90F for the first time this season along portions of the
I-95 corridor on Wednesday and Thursday.

Strong high pressure will gradually shift offshore Monday allowing
for seasonable warm air to push north on southerly flow.  This
surge of warm air both at the low levels and aloft will push surface
temps into the the low 80s Monday, the mid 80s Tuesday and into the
upper 80s to low 90s for Wednesday and Thursday. Temperatures
toughing 90F in Philadelphia would mark the first 90 degree day of
the year and the first since September of last year. As is typical
in spring though, temperatures along and near the coast likely will
be 15-25 degrees cooler due to the colder sea surface temperatures.
In addition to the strong WAA, winds could end up being fairly gusty
later in the as the surface inversion starts to erode. A low level
jet will bring 35-45 kts close to the surface however with the
inversion in place it will take most of the day to erode it and
along the coast it will likely not erode.  Southerly gusts of 20-
25kts can be expected Monday afternoon.

A series of weak disturbances will result in a slight chance to low-
end chance (15-30%) for showers or even an isolated thunderstorm
Tuesday through Thursday, primarily in the evening hours and
primarily for areas northwest of the I-95 corridor. The bulk of the
period will be high and dry however, not good news for the drought.

&&

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

Tonight...VFR. Winds around 5 kts or less, favoring a northerly
direction. High confidence.

Sunday...VFR. Winds east around 5-10 kts in the morning shift to
the S-SE and gust to 15-20 kts in the afternoon. High
confidence.

Outlook...

Sunday Night...VFR. LLWS possible.

Monday through Monday Night...VFR. Slight chance of a
shower/thunderstorm (15-20%) at KRDG/KABE in the afternoon. A low
level jet will likely cause some issues with LLWS and turbulence
with surface wind gusts out of the southwest around 20-25 kt during
the day.

Tuesday through Tuesday Night...VFR. Slight chance of a
shower/thunderstorm (15-20%) at KRDG/KABE in the afternoon.

Wednesday...VFR. Slight chance of a shower/thunderstorm (15-20%) at
KRDG/KABE in the afternoon.

&&
