Area Forecast Discussion
National Weather Service Mount Holly NJ
900 PM EDT Thu Apr 11 2024
.SYNOPSIS...
A warm front moves north of the region this afternoon. A strong
cold front crosses our area tonight into early Friday. High
pressure will build to the south later Saturday through Sunday,
with a weak cold front that may move through towards the end of
the weekend.
&&
.NEAR TERM /THROUGH FRIDAY NIGHT/...
845 PM...Based on the latest analysis this evening, I have a
growing concern for strong to potentially even locally severe
thunderstorms affecting parts of the area overnight. Meanwhile,
low pressure was centered near Ohio as of 8 PM this evening and
this is moving NNE and deepening with time. A cold front extends
southward from this feature through West Virginia into western
Virginia and North Carolina and it is along and ahead of this
feature strong to severe storms (warnings being issued) have
formed and are moving off to the east and northeast. Meanwhile,
other than a few showers around it's relatively quiet at this
time across the mid Atlantic. However as we go through the late
evening into the overnight expect the cold front and an
associated potent upper level trough to approach from the
southwest. Despite the time of day, think there's a good chance
that the strong shortwave and upper level jet forcing aloft
along with the warm advection pattern will keep showers and
storms going as they approach from the south and west. The most
active period of these showers/storms moving through our area
looks to be from roughly 2-6 AM. The big question of course is
how strong will they be in terms of winds. A limiting factor
will be the relatively stable boundary layer in the low levels
that could help limit the potential for damaging winds. That
said though, with 40-50 knot winds not too far off the deck in
the lowest 1000 feet it won't take much to bring these down. So
I think that potential is there for at least some isolated
damaging wind gusts to occur overnight...especially over
Delmarva into SE PA and southern NJ. Aside from this, the
gradient wind will remain strong regardless of what the
convection does and so for coastal areas a Wind Advisory
remains in effect where we expect SSE winds 25 to 35 gusting up
to 50 mph overnight. Farther inland the winds should generally
be 20 to 30 gusting up to 40 mph except where heavier
showers/storms could bring stronger winds down to the surface in
places as discussed above. The other thing that will have to be
watched is the heavy rain and associated flooding threat. The
flood threat this time will be more of the urban, small stream,
low lying and poor drainage type flooding to the fairly
progressive nature of the system but it will still need to be
watched. The Weather Prediction Center continues to highlight a
SLIGHT risk of excessive rainfall (at least 15 percent chance)
extending into NE PA with the remainder of the area in a
MARGINAL risk (at least a 5 percent chance). The other thing is
coastal flooding and this is discussed in the Tides/Coastal
Flooding section below. Temps will stay fairly elevated
overnight with the strong southerly flow and clouds, mostly
staying near or above 60.
Front now doesn't look to pass much of the area until later
morning on Friday, so we'll probably get another round of
showers and isolated storms as the actual front crosses the
region during the morning. This should be more progressive so
looks like any flood threat should have dwindled by this time,
but locally gustier winds can still occur. After front passes,
we'll see a shift to a southwesterly wind, with sustained speeds
dropping a bit but gust over land increasing a smidge... i.e.,
most land areas away from the coast likely see their strongest
gusts behind the cold front Friday. Temps will be steady or
slowly fall, with reading remaining fairly close to 60 or so.
Cold advection kicks in stronger after sunset Friday night, but
clouds linger as upper trough may bring some more showers back
to the region after another lull. Lows mostly in the 40s. A few
snowflakes can't be ruled out in the Poconos where lows will
drop into the 30s.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Saturday through Saturday Night while brisk should be fairly dry.
Slight chance of showers (15-25%) in the morning north of I-78 as
the area of low pressure moves away. Strong flow combined with some
cold air advection and deeper mixing will result in breezy to windy
conditions, with the stronger winds occurring during the day time
hours on Saturday when mixing is more maximized. Gusts up to 40 MPH
are possible, especially in the higher terrain locales. The winds
then diminish Saturday night with less vertical mixing. Temperatures
will be a few degrees below normal, in the mid to upper 50s and low
60s. Lows on Saturday Night will be in the low to mid 40s.
High pressure starts building in Sunday with temperatures warming
and getting into the 70s. However, a mid level wave looks to move
through late Sunday afternoon through early Monday morning and
should bring some showers and possibly a thunderstorm across the
Lehigh Valley/Poconos and northern NJ. It will stay mild through
Sunday night with overnight lows in the 50s.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
Flow aloft through the early week shifts from zonal to more of
a northwest pattern as a ridge starts to build over the Great
Lakes. At the surface this will allow higher pressure to build
and temps to warm each day with, with temperatures expected to
get well above normal for most of next week. Can't rule out some
highs in the 80s, especially for the middle of next week.
Showers and possibly a few thunderstorms likely return late
Tuesday into Wednesday along a stalled boundary that begins to
lift as a warm front. However, this system does not look overly
impactful at this time.
&&
.AVIATION /01Z FRIDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas...
Tonight...Mainly IFR overnight tonight with showers and the
potential for some thunderstorms as well by the overnight
period. SSE winds 15 to 20 gusting up to 30 knots inland and up
to 40 knots at ACY. LLWS will also be quite strong with low
level winds from the south at 55 to 65 knots at 2000 feet.
Moderate confidence.
Friday...Still some showers and even the chance of a couple
storms in the morning as the cold front moves through but
conditions improving to MVFR in the early to mid morning and
then VFR in the afternoon. Winds shifting to southwest through
the morning and eventually more westerly at 20 gusting up to 30
knots. Moderate confidence.
Outlook...
Saturday...Sub-VFR conditions possible to start the day, but
should lift to VFR by late morning. Gusty W/NW winds with gusts
30 to 35 kt possible.
Saturday Night...VFR expected.
Sunday through Sunday Night...Sub-VFR conditions possible with
periods of showers and/or thunderstorms.
Monday through Tuesday...VFR expected. No significant weather.
&&
.MARINE...
Strengthening southerly flow ahead of approaching cold front
still looks likely to bring gale conditions to all waters
tonight in to early Friday, with waves building to 7-13 ft.
Higher gusts can't be ruled out with any passing stronger
thunderstorms. Winds shift southwesterly on Friday with speeds
subsiding to Small Craft Advisory levels, then drop below SCA
levels at night, but waves remain elevated at 5-8 ft.
Outlook...
Saturday through Saturday Night...Small Craft Advisory conditions
expected, with gales possible (50%), mainly during the day.
Sunday...Sub-SCA conditions expected.
Sunday Night...SCA conditions possible (30-40%) as wind gusts
approach 25 kt.
Monday through Tuesday...Sub-SCA conditions expected.
&&
.TIDES/COASTAL FLOODING...
Water levels have remained elevated over the last week with
flood levels ranging from spotty minor to widespread minor. This
will continue through tonight and tomorrow morning's high tide,
though some locations will get to moderate, possibly even major
flood.
The evening/overnight high tide is expected to be more
significant compared to previous high tides. Coastal Flood
Warnings are in effect for the coastal areas along the northern
Delaware Bay and the tidal Delaware River. Guidance between
STOFS, ETSS, PETSS all strongly points to moderate flooding over
this region with the PETSS and bias corrected STOFS guidance
suggesting near major flooding possible at Burlington. PETSS has
been performing the best, so we have to put some stock into
this solution. However, the last 2-3 cycles of STOFS and PETSS
have been running a bit high so I tend to think that the
flooding should stay below major flood stage.
The Chesapeake Bay is a bit of an outlier and confidence is low
to moderate overall. Since we are now within 24 hours, a Coastal
Flood Advisory has been issued for tomorrow morning's high tide.
Guidance through today has come down slightly, both at
Tolchester Beach and Claiborne, though a wide spread remains
among members. Looking at observations, and how guidance did
with this morning's high tide, the thinking is that both
locations will stay in minor flood. Cannot rule out moderate
flooding though, especially at Tolchester Beach, and an upgrade
to a Coastal Flood Warning is possible. Regardless, tidal
flooding is expected, and any residents should take preventative
actions now before flooding begins tomorrow morning within the
Eastern Shore of Maryland.
For the rest of the Atlantic coastline, went ahead and issued a
Coastal Flood Advisory for tonight for all sites. Added Perth
Amboy to the Advisory for tonight. Sites along the northern New
Jersey coast are forecast to get right to advisory minor.
However, guidance for the back bays suggests most sites getting
into at least minor flood. Some spotty moderate flooding is
possible, specifically at Mantoloking, where some of the
guidance brings that site above moderate stage.
Monitor the latest total water level forecasts for future
updates.
