Area forecast discussion, Jul 17, 4:15 AM EDT, 26 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
415 AM EDT Mon Jul 17 2023
.SYNOPSIS...
A break in the active wet, humid weather on Monday will give way
to yet another warm, muggy day with thunderstorms possible
Tuesday as another cold front approaches. Later in the week, a
more potent cold front may pass through later Thursday or
Friday, possibly giving way to a drier weekend.
&&
.NEAR TERM /THROUGH TONIGHT/...
Dense fog advisory now in effect for all of our NJ zones.
Elsewhere in the region, fog is either not very dense or not
widespread.
Today will be the more tranquil of the next few days. Mid level dry
air advection will be working into the region. A weak mid level
short wave trough is expected to lift northeast, generally staying
north of our region. There is a slight chance (20%) for showers and
storms, first this afternoon in the vicinity of the sea breeze
(which will likely stay rather close to the coast thanks to westerly
flow further inland). The other chance for showers and storms comes
tonight as the next short wave trough approaches the region from the
west. The trough should stay pretty far west so precip chances
through the overnight are confined to the Poconos and Berks County.
In both cases, precipitable water values will be significantly lower
than we've seen the last few days, so the risk for heavy rain is
low.
Although a cold front passed through the region on Sunday,
temperatures will still be a few degrees above normal, though with
the drier air, it should feel more comfortable today than it has the
last few days.
&&
.SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/...
Persisting upper-level low pressure spinning across Ontario that
has been plaguing our region with continued unsettled weather
will finally start shifting eastward to Quebec on Tuesday. That
will send yet another trough eastward across the Great Lakes and
Appalachians, though it will tend to weaken and pull northward
before it arrives here. Still, it appears there will be enough
forcing to kick off some more showers and thunderstorms Tuesday
afternoon and evening. Would not even rule out some showers or a
stray storm around the Poconos into northwest NJ in the morning.
CAMs and HREF suggest the focus will become northern NJ,
perhaps toward the coast in particular, but would not rule out
at least isolated thunderstorms anywhere in our region. While I
don't have much confidence in timing, models suggest this
trough will push through early in the evening, so activity
should end fairly quickly rather than lingering into the night
like some of our recent rounds of convection. While dewpoints
take a step back on Monday, 70F+ dewpoints will surge back
northward across the Delmarva and up the NJ coastal plain on
Tuesday. Mediocre lapse rates may hold back CAPE, but bulk shear
of 25-30 kt will be enough to support stronger convection, and
the moist environment suggests that localized flooding may be an
issue, even while storms appear they will not linger in any one
spot for very long. WPC ERO has portions of NJ in a slight risk.
SPC does not have us highlighted, but would not rule out an
isolated severe storm.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
In short, the long term portion of the forecast remains
generally unsettled. The driest day appears to be Wednesday as
we are caught in between disturbances. Some mid-level energy
looks to skirt across the southern Delmarva late Wednesday into
Wednesday night, so mentioned a chance of showers/storms
possible across the Eastern Shore of MD and DE possibly
squeaking into SE PA and S NJ. Otherwise, the northern portion
may have a fairly pleasant day with a little lower humidity and
some partial sunshine, with highs mainly in the 80s.
Thursday and Friday, unfortunately look to hold on to the
active pattern we have seen over the past few weeks, as the
departing upper-low lifting out of eastern Canada is replaced
with yet another potent trough dropping across eastern Canada
and the Great Lakes, with the longwave trough persisting. Have
followed guidance from the NBM, with generally precipitation
chances between 30-50% each day. There will probably be one or
two periods of fairly widespread shower and thunderstorm
activity, but exact timing of the trough and associated cold
front passage is uncertain. Weak high pressure may build in over
the weekend allowing for at least a dry day or two accompanied
by high temperatures in the low to mid 80s and relatively lower
humidity. However, there is some uncertainty given this far into
the future, and it still looks like the longwave trough will
be lingering over the Great Lakes.
&&
.AVIATION /07Z MONDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Through 12Z...Transient fog has developed at most TAF sites. These
visibility restrictions should continue through the overnight hours.
KTTN, KMIV, and KACY have the greatest risk for persistent LIFR
restrictions (one note, there remains a comms issue with KACY, so
still carrying AMD NOT SKED on that TAF). Variable wind 5 knots or
less. Medium confidence on the overall pattern, but low confidence
on the timing details of the fog.
Monday...Mostly VFR conditions. The only exception is that haze
advected in from Canadian wildfires may result in MVFR visibility
restrictions, but low confidence at this point on how much
visibility restrictions we will see. Northwest wind less than 10
knots, becoming southwest. High confidence on the overall pattern,
but low confidence on visibility restrictions.
Tonight...Mostly VFR conditions expected, though there is a slight
chance (20%) for showers and storms at KRDG resulting in visibility
and ceiling restrictions very late tonight. Light winds (5 KT or
less). While direction may be variable at times, it should generally
favor southerly. Moderate confidence.
Outlook...
Tuesday...VFR in the morning, with sub-VFR conditions possible
in the afternoon with showers and thunderstorms possible, mainly
north of PHL. S-SW winds of 5-10kts during the day, becoming
5kts/less at night. Moderate confidence.
Wednesday...VFR expected. A few evening showers and
thunderstorms possible but probably staying south of ILG. S-SW
winds of 5-10kts. Moderate confidence.
Thursday and Friday...A cold front may move through with a
period of more widespread showers and thunderstorms. VFR with
times of MVFR and IFR around thunderstorms. SE-S winds of
5-10kts, shifting to more westerly behind the front. Moderate
confidence.
&&
.MARINE...
Fog persists especially on the NJ coastal waters. It has been
more transient on the Delaware coastal waters and the Delaware
Bay, so will continue to monitor through sunrise, but the
advisory there may be able to be cancelled early.
Winds and seas are expected to remain below Small Craft Advisory
criteria through tonight. Some guidance has seas at 5 feet,
especially further off shore through mid day today, but that has yet
to develop, and is unlikely that we will see any significant
increase in seas over the next few hours, so have kept the seas
forecast below 5 ft for now.
Outlook....
Tuesday and Wednesday...No advisories will be needed. Isolated
showers and thunderstorms possible each afternoon/evening,
mainly north of Barnegat Light on Tuesday, then south of
Barnegat Light on Wednesday. S-SW winds around 10 kt with seas
of 3-4 feet.
Thursday and Friday...A cold front will come through with a more
widespread round of showers and thunderstorms, but timing is
uncertain. We do not anticipate any small craft advisories, with
southerly winds shifting to westerly behind the front, around 10
to 15 kt, and seas generally around 3 ft.
&&
.HYDROLOGY...
Due to continued runoff from rainfall over the weekend, we have
a several river gauges running above 'action stage', and even a
couple of non-forecast points in minor flood in Warren County
NJ, where rainfall was particularly heavy on already saturated
soils. Most sites have crested, but we are still keeping a close
eye on the Nanticoke River at Bridgeville. That area saw 4 to 6
inches of rain on Sunday, and while the river appears to be near
cresting, it is nearing minor flood stage. In Warren County,
Paulins Kill at Blairstown will drop back below flood stage
early this morning, while Beaver Brook at Belvidere has crested
and should drop below flood stage at some point today.
