Special Weather Statement, NWS Philadelphia/Mount Holly

Area Forecast Discussion
National Weather Service Mount Holly NJ
525 PM EDT Mon Aug 13 2018

.SYNOPSIS...
A weak front will move little through Tuesday as weak surface
lows move through the northern Mid-Atlantic along it. The front
will move offshore Wednesday. Low pressure will move from the
Great Lakes on Thursday to New England and adjacent southeast
Canada on Saturday. An attendant cold front will progress
through the region Friday night and Saturday but is expected to
stall near or just south of the area through early next week.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
515 pm update: Updated PoPs across the area for the evening
hours. Convection in central Maryland is expected to progress
to the Eastern Shore during the next few hours. Convection-
allowing models indicate (to varying degrees) these storms will
gradually diminish after sunset, but this process could be slow
given the high moisture content of the air and associated
slowing effects on diminishing instability. Additionally,
convection currently in central PA suggests that the environment
may be recovering sufficiently for subsequent development
farther south and east into south-central/southeast
Pennsylvania before sunset. Starting to see some radar echoes in
Berks County, indicating this threat may be increasing. The
HRRR gives some indication of this, though it is notably not
handling convection in general well this afternoon.

Also made some adjustments to temperature/dew
point grids through the evening hours, as current readings were
higher than forecast in southern New Jersey and portions of
Delmarva.

Previous discussion...

Several flood warnings remain in effect across the area as a result
of the heavy rain that fell this morning (5-8 inches in some spots).
Please follow detours and do not drive around barricades. Turn
Around, Don't Drown!

An upper level closed low slowly moves across the region tonight.
Meanwhile, at the surface, low pressure will continue to move along
a stalled boundary and up our coast this evening.

Scattered convection is occuring in the forecast area, especially
across parts of the region that have been able to see some sunshine
today. While the storms are moving, there is not a lot of low across
the region and this means the storms will move slowly, if at all.
The slow nature of the storms combined with the high PWATs across
the region means that the storms will be efficient rainmakers and
heavy rain will fall. As the sun sets, we should see storms diminish
in coverage as the instability is largely driven by surface heating
this afternoon and evening. Energy will continue to rotate around
the upper low and we could see some showers continue through the
overnight period as a result. With the wet antecedent conditions and
keeping in mind that a good deal of rain fell across portions of the
area this morning, we have kept the Flash Flood Watch in place
through tonight.

Model shows that we could see some clearing tonight across the
region. With light winds and a lot of low level moisture in place,
some fog may develop.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
The upper low will start to move slowly to the northeast on Tuesday.
At the surface, the stalled frontal boundary will move little but
should make a slight shift towards the coast. Another wave of low
pressure is forecast to move along this boundary, bringing in
another round of convection and showers through the day. Highs will
generally be in the 80s across the region, with some 70s across the
southern Poconos and parts of northwest New Jersey.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
With a plethora of short-term concerns, spent little time on the
long-term forecast today. In general, the details have not
changed much for the rest of the week into the following
weekend.

The midlevel trough plaguing the Northeast early this week will
be ejecting into the Canadian Maritimes and offshore the New
England coast on Tuesday night and Wednesday. Lingering chances
of precipitation Tuesday night (especially offshore and in the
northern CWA) will decrease with time. Kept PoPs out of the
forecast Wednesday, but I am a little concerned about an
upstream (weak) vort max moving southeastward into southern New
England. The 12Z NAM hints at some convection breaking out
during the day, though it looks like the most favored locations
for such convection are north of the area. Nevertheless, would
not be surprised if we need to add some PoPs to areas near/north
of I-80 in later forecasts. Otherwise, the rest of the region
will see rising heights and partially or mostly sunny skies.
This spells a hot day for the area.

Shortwave ridging enters the area Wednesday night and Thursday.
Associated large-scale subsidence should allow for a dry period
and warm temperatures. Kept temperatures close to a statistical
blend, but I suspect highs will need to be nudged upward in
subsequent forecasts given observed model biases in the past.
MEX guidance is particularly warm on Thursday, with heat indices
in the upper 90s in much of the urban corridor and Delmarva.

Next system approaches the area on Friday and Friday night, with
a surface low progressing from the Great Lakes to the Northeast
during the period. A cold front will progress into the
Appalachians during the day and enter the CWA by Friday night.
Timing differences exist among the operational simulations, but
the overall evolution is reasonably similar at this time range.
Given timing of the front, convection looks to peak in intensity
west of the area during the afternoon (possibly affecting the
western CWA) and nocturnally weaken as it moves into the heart
of the region. Severe threat looks fairly low anyway given the
weak shear and CAPE profiles.

Of more concern is what happens to the front this weekend, as
there are indications it may slow to a crawl near or south of
the CWA. To varying degrees, operational models show subsequent
rounds of convection developing along the increasingly quasi-
stationary boundary. We've seen this scenario before (many
times) this summer, with indications another heavy rain event
may occur somewhere in the Mid-Atlantic during this time frame.
There is some consensus that the southern CWA may be most at
risk for this (in our area), but model discrepancies are large
by this point. The pattern, though, suggests that this is yet
another period to watch closely in the upcoming days.

&&

.AVIATION /21Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

This afternoon...Mainly VFR conditions with some MVFR ceilings
around the region this afternoon. Scattered showers and thunderstorms
may result in locally reduced ceilings and visibilities through this
evening. Winds are light this afternoon, generally out of an east or
northeast direction.

Tonight...VFR conditions from KPHL and south with MVFR/IFR possible
at KABE, KRDG, KTTN overnight in fog/stratus. Winds become light and
variable overnight.

Tuesday...Mainly VFR conditions to start the day. Scattered showers
and thunderstorms develop with MVFR/IFR conditions possible. West to
southwest winds around 10 knots or less.

OUTLOOK...
Tuesday night: May see some remnant showers/storms north and
east of the Philly terminals, but chances should diminish with
time. There is also some potential for patchy fog. West winds
generally below 10 kts. Low confidence.

Wednesday: VFR. Winds west 5 to 15 kts. Moderate confidence.

Wednesday night and Thursday: Predominantly VFR, but there may
be some patchy fog between midnight and 8 am or so, especially
at the more susceptible sites. Light/variable winds Wednesday
night becoming southwest 5 to 10 kts on Thursday. Moderate
confidence.

Thursday night and Friday: Predominantly VFR, but increasing
chances of showers/storms through the period, with local sub-
VFR conditions possible. South to southwest winds 5 to 15 kts.
Moderate confidence.

Friday night and Saturday: A chance of showers/storms,
especially Friday night. Local sub-VFR conditions probable, and
longer-duration sub-VFR conditions possible in proximity to a
frontal passage. Southwest winds 5 to 15 kts in advance of the
front Friday evening/night becoming west or northwest behind the
front Saturday. Low confidence.

&&

.MARINE...
Sub-Small Craft Advisory conditions are expected to continue across
the area waters. A boundary across the waters has the winds in
different directions this afternoon, with northeast winds across the
northern waters and southwest winds across the southern waters.
Winds should become more southwest overnight and then pick up around
10 to 15 knots for Tuesday. Seas are 2 to 4 feet on the ocean and
around 1 to 2 feet on the Delaware Bay.

OUTLOOK...
Tuesday night through Saturday: Sub-advisory winds/seas
expected, though seas may approach advisory levels on Friday and
Saturday as a cold front approaches the region. A chance of
showers/storms Tuesday night and again Friday and Saturday.

RIP CURRENTS...
There is a low risk for the development of dangerous rip
currents today and Tuesday.

&&

.TIDES/COASTAL FLOODING...
We are expecting spotty minor coastal flooding with this
evening's high tide. It will be due mainly to the high
astronomical tides associated with the new moon. However, the
flooding due to the tides is not anticipated to be widespread
enough to warrant another Coastal Flood Advisory at this time.
We will continue to monitor gauges closely, especially given the
heavy rainfall that has occurred today in Monmouth/Ocean
Counties.
