Area forecast discussion, Sep 7, 4:18 PM EDT, 2 hours 12 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
418 PM EDT Thu Sep 7 2023
.SYNOPSIS...
A weak surface trough will become established across parts of
our region today well ahead of a cold front. The cold front is
forecast to arrive during Friday before stalling in our region
over the weekend, then this front finally shifts offshore during
early next week. Another cold front looks to arrive later
Wednesday.
&&
.NEAR TERM /THROUGH FRIDAY/...
While the mid and upper-level ridge of high pressure responsible
for our heat wave this week has shifted offshore, today has
turned out to be the hottest day overall for most of our area.
Temperatures may not be quite as hot as some days earlier this
week across area farther northwest of I-95 and near the coast,
but it is more humid, with dewpoints well into the low 70s at
most locations. Some sites near the urban corridor including PHL
have already topped out near 97F, with another hour or two of
heating possible. The heat advisory remains in effect until 8
PM. With a bit more cloud cover and slightly lower temperatures
tomorrow, heat indicies may only near 100F right around
Philadelphia, so it is possible we will need another localized
heat advisory there for Friday, but will hold off for now since
it looks so marginal and localized.
With high pressure shifting offshore, southerly flow has
advected moisture including those higher dewpoints northward
into our region. Most model guidance was not aggressive enough
with this, and the resulting SB CAPE values near 4000 j/kg over
eastern Pennsylvania. This may have been why most guidance,
aside from perhaps the NAM NEST, did not indicate much in the
way of local thunderstorm development until later this
afternoon. However, discrete thunderstorms fired up around Berks
County to the Lehigh Valley and northward early this afternoon,
with some decent mid-level lapse rates and just enough shear
supporting severe thunderstorms that produced at least a few
instances of severe hail around quarter-sized. These storms have
lifted out for the most part. A Severe Thunderstorm Watch is in
effect in our area, mainly northwest of I-95, through 9 PM this
evening, as additional activity will move in, associated with
the main shortwave lifting northeastward from West Virginia
across Pennsylvania, and eventually toward northern NJ this
evening. With the increasing forcing, more widespread
thunderstorms merging into clusters and short lines will present
more of a damaging wind threat, though would not rule out some
localized reports of marginally severe hail still. Hi-res
modeling suggests the bulk of this activity will pass by between
4 PM and 9 PM from southwest to northeast. Some isolated and
probably weaker showers and thunderstorms may reach as far
southeast as I-95, but hi-res modeling along with more
convective inhibition & diminishing forcing closer to the
offshore ridge suggests that storms will struggle to make it too
far southeast. The shortwave will pass by late this evening,
with weakening showers lifting northeast into and north NJ and
New York, with a mainly dry night thereafter. Some patchy fog
may develop in areas where it rained, with another muggy night
ahead. Marine layer stratus and perhaps a bit of fog may push
onto the NJ shore toward morning as well.
For Friday, expect a mainly dry start to the day with showers
and thunderstorms developing toward midday or early afternoon as
another shortwave passes by in the south-southwest flow aloft,
while the main cold front slowly begins to approach our region
from west of the Appalachians. With more in the way of clouds
around and subsequently lower temperatures and low-level
heating, CAPE may be more limited than it is today, and the
shortwave does not look quite as strong as the one passing
through on Thursday. That said, overall the environment looks
very similar, and SPC has portions of our area in another Slight
Risk for Severe Thunderstorms, with the main threat being
damaging winds. Hi-res guidance seems to indicate storms will
develop locally possibly as early as midday, perhaps near or
just northwest of I-95, then gradually drift southeastward.
There may be more of a heavy rain and localized flooding threat
compared to today, particularly if any storms persist in urban
areas.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
Overall, the short term forecast remains on track. Conditions are
still expected to be a little cooler Saturday however still humid
with some showers and thunderstorms. As an upper- level trough
remains to our west, a weak cold front will be moving through our
region Friday night before stalling across our region into Saturday.
Convection from daytime Friday should tend to be on a downward trend
Friday night as the boundary layer cools and some areas become
worked over assuming some more organized convection occurs.
There may be a repeat performance on Saturday, although temperatures
will be a bit cooler and therefore the instability is forecast to be
lower. In addition the shear looks a little less, however ample
boundary layer heating should lead to steepening low-level lapse
rates once again. This would still support some convectively
generated strong surface wind gusts if strong enough convection
develops and especially if it organizes some. In addition, the
precipitable water values will be in the 1.5-2 inch range through
Saturday and therefore convection will produce locally heavy rain.
We can certainly use the rain as it has been dry, therefore the
overall flash flood risk may be more limited unless training of
convection occurs.
With the boundary beginning to move through the region and continued
cloud cover, high temperatures Saturday are forecast to be in the
mid to upper 80s for most locations.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Summary...Cooling temperatures and gradually lowering dew points
along with continued chances for some showers and thunderstorms
(potentially drier Tuesday).
Synoptic Overview...The axis of an upper-level trough initially to
our west is forecast to work across our area during Monday and
gradually weaken. A much stronger upper-level trough is forecast to
move across the Great Lakes region and adjacent Canada early in the
week before gradually shifting into the Northeast. The timing of
this feature will depend on the amplitude of it and if it closes off
or not. At the surface, a weak cold front draped across our region
Sunday into Monday is forecast to finally get pushed offshore into
Tuesday. The next cold front looks to arrive later Wednesday with a
reinforcing front possible on Thursday.
For Sunday and Monday...The axis of a gradually weakening upper-
level trough is forecast to arrive later Sunday and then cross our
region Monday. This will keep a weak surface front draped nearly
north to south across our area. Given some cooling aloft and some
additional forcing for ascent with the trough aloft, some increase
in convective development should occur each day especially in the
afternoon and early evening hours. While there will cooler
temperatures it will remain humid, however the instability will be
held down some which should mostly lower the severe thunderstorm
risk. Locally very heavy rain will be probable due to high
precipitable water values and potentially slower storm motions,
however the region needs the rain and this could limit the flash
flooding threat.
For Tuesday through Thursday...The weak cold front should be
offshore to start Tuesday with some drier air working in. This may
provide a window for no convection chances, however the next upper-
level trough working across the Great Lakes and toward the Northeast
will drive a cold front into our area later Wednesday with another
front possibly developing in its wake for Thursday. The details with
this front and the extent of convection will depend on the amplitude
and timing of the trough and associated surface cold front. The
surface dew points should lower some more Tuesday but then may creep
upward some Wednesday ahead of the next cold front.
We will continue to monitor Hurricane Lee, however the exact track
is uncertain so far out in time and therefore so are any possible
direct impacts. Increasing swells and rip currents into our area
however do look to become more likely with time.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Through 00Z...Mainly VFR from I-95 southeastward. Scattered
showers and thunderstorms around KRDG and KABE, with some MVFR
and even brief IFR VSBY restrictions possible. Some isolated
thunderstorms may creep close to the I-95 vicinity toward 00Z.
Southerly wind 5 to 10 knots. Medium confidence.
Tonight...Scattered early evening showers and thunderstorms
northwest of I-95, but would not rule out passing shower or even
a rumble of thunder near the TAF sites between ILG,PHL,PNE and
TTN. There is some indication that more extensive marine stratus
may develop and push onshore later this evening, and
particularly after 06Z, but so far not seeing much evidence of
that coming to fruition over the ocean on visible satellite.
Thinking it is unlikely that the I-95 TAF sites end up with any
restrictions, but ACY and even MIV could see IFR ceilings and
perhaps even some fog. Variable wind 5 knots or less. Medium
confidence.
Friday...VFR initially along most of the I-95 corridor, but
outside of that expect some patchy low clouds and fog with IFR
and even LIFR conditions possible in some spots including RDG
and ACY. Showers and thunderstorms develop midday or early
afternoon, by 18Z, and may impact much of the area, but mainly
inland from the coast. Periods of MVFR ceilings and MVFR/IFR
VSBY possible in/near any thunderstorms, with locally gusty and
erratic winds possible.
Outlook...
Saturday and Sunday...Periods of sub-VFR conditions probable along
some showers and thunderstorms. Greatest chance for showers and
thunderstorms is each afternoon and evening. Southerly winds 5-10
knots each day decreasing to 5 knots or less each night. Low
confidence.
Monday...Periods of sub-VFR conditions probable especially with some
showers and thunderstorms. Southwest to westerly winds 5-10 knots,
becoming northwesterly around 5 knots or less Monday night. Low
confidence.
Tuesday...Mainly VFR. Sub-VFR conditions possible with chances for
showers. Northerly winds around 5 to 10 kts. Moderate
confidence.
&&
.MARINE...
Conditions will remain below Small Craft Advisory criteria
through Friday. Winds S-SE 10 to 15 knots for this afternoon,
diminishing near shore and over DE Bay tonight, but otherwise
persisting into Friday. Waves on our ocean waters are expected
to be 2 to 3 feet, with waves on Delaware Bay at 2 feet or less.
Outlook...
Saturday through Monday...No marine headlines expected. Main concern
will be for showers/storms, though best coverage looks to stay
inland away from the waters. Winds generally southerly 10-15 kts.
Seas 2 to 4 ft.
Tuesday...Small Craft Advisory conditions possible. Seas begin to
build and may begin to approach 5 feet on Tuesday. Otherwise,
northerly winds around 10 knots.
Rip Currents...
A southwest wind 5 to 10 MPH this morning is forecast to become
south 10 to 15 MPH this afternoon along the coasts of Delaware
and New Jersey. Breaking waves are expected to be 1 to 2 feet
with a long period (around 10 second) easterly swell. We will
continue to carry a LOW risk for rip currents today.
A southerly wind is expected to increase to 10 to 15 MPH on
Friday with breaking waves of 1 to 2 feet. A long period
easterly swell (around 11 or 12 seconds) is forecast. Being that
conditions will likely be similar to those of today, we will
keep the mention of a LOW risk of rip currents.
