Area forecast discussion, Aug 4, 3:37 PM EDT, 5 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
337 PM EDT Tue Aug 4 2020

.SYNOPSIS...
Tropical Cyclone Isaias is north of New Jersey and will continue
to track into New England this evening. High pressure will begin
to build in from the west later this week as a weak frontal
boundary remains stalled across the Mid-Atlantic.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Tropical Storm Isaias is north of New Jersey and will continue
to track to the north and east tonight. Some lingering rain
continues across the southern Poconos and northern New Jersey,
but otherwise, the heavy rain has ended. The Flash Flood Watch
has been cancelled, although there is lingering areal flooding
and river flooding across the region.

Winds have turned or will turn west shortly, but still gusting
fairly strong. Winds should diminish shortly after sunset.

An upper trough with strong shortwave energy will nose in from
the west later tonight, and additional scattered showers and
thunderstorms may develop this evening before ending after
midnight.

A warm and muggy night on tap with lows in the 60s.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
Surface high pressure builds in from the west during the day,
but some shortwave energy will approach from the west as the
base of that trough lifts north of the region. Most of the area
should be dry and sunny, but cannot rule out isolated showers
and thunderstorms in the afternoon across southern areas. Warm
and humid with highs in the 80s.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
A fairly typical but overall quieter summer pattern is expected
for the long term forecast. The mean upper level trough over
the east will lift out but the mid Atlantic region will remain
in a fairly moist W/SW flow regime around high pressure ridging
over the western Atlantic. This will result in chances for
scattered showers/storms most days that will be mainly diurnally
driven meaning the best chances will be in the afternoon and
early evening. Temperatures will be around average for this time
of year.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Into the evening...Rapidly improving CIGS/VSBYS early with rains
departing NE. VFR by 20/21z for the N/NE most sites. Strong W winds
with gusts 40 to 50 knots early then the gusts will decrease back
closer to 20 kts by sunset.

Tonight...VFR. Decreasing clouds. Decreasing winds. Areas of fog
possible after midnight. I will likely include some fog in TAFS with
AMDS this afternoon.

Wednesday...VFR conditions expected with some few/sct daytime CU
expected. Winds mostly W to SW at 5 to 10 knots.

Outlook...

Wednesday night through Saturday...Mostly VFR. Scattered
SHRA/TSRA possible each afternoon/evening that would result in
brief sub-VFR conditions at a given terminal. Fog may develop
during the overnight. Winds east to northeast Thursday through
Saturday. LGT/VRB at night. Moderate confidence.

&&

.MARINE...
Tonight...Tropical Storm conditions will end this evening, and
Small Craft Advisories will probably be needed for several hours
as conditions improve.

Wednesday...Lingering 5 foot seas possible in the morning,
otherwise, sub-SCA conditions with SW winds around 10 kt. Ocnl
gusts to 20 kt possible in the afternoon.

Outlook...

Wednesday night through Saturday...Sub-advisory winds/seas
expected through the period. Chances of showers/storms through
the period, especially in the afternoon/evening hours.

Rip Currents...

On Tuesday, impacts from Isaias will increase the rip-current risk
level to high. In addition, high surf is expected. A rip
current risk statement and high surf advisory are in effect for
this period, so in conclusion Tuesday will not be a good day to
be at the beach.

The rip current risk will likely remain elevated on Wednesday.

&&

.HYDROLOGY...
Between 3 and 6 inches of rain, with localized amounts of 8 to 9
inches, have fallen across much of southeast Pennsylvania,
western New Jersey, and Delmarva. Flooding continues across
these areas. Please refer to any Flood Warnings for details.

&&

.TIDES/COASTAL FLOODING...
The coastal flooding impacts from Isaias remain very uncertain
at this time. Models notoriously handle fast-moving, intense
cyclones poorly in our area, as the short duration of onshore
flow competes with the strength of the winds. These competing
impacts and sensitivities are not well understood from a
modeling standpoint, leading to rather large spread in the model
guidance.

Coastal flooding impacts are expected across the area today,
with four different regions we will be monitoring. The first,
and potentially most significant, is for the eastern shore of
Chesapeake Bay, where surge will likely move northward during
the day. What is unclear, however, is the strength of this
surge. Model guidance is particularly poor for these areas, and
the output the past couple of days seems unrealistically low.
However, the extent of impacts remains quite unclear. At this
point, there is potential for moderate flooding, which requires
continuation of the coastal flood warning. However, it is
possible impacts will be less significant/widespread. We will
likely not have a better idea of impacts until after daybreak,
when gauges in lower Chesapeake Bay begin to respond.

The second area is Delaware Bay. The real question here will be
the timing of the surge relative to the astronomical high tide.
With guidance trending a little faster with the surge, the
timing looks a little less favorable for coincidence of peak
surge and astronomical high tide for the Delaware Bay sites.
Nevertheless, the strength of southeast winds in advance of
Isaias may compensate much more readily than models suggest. A
coastal flood advisory has been issued here for the entire day
given the uncertainty of peak surge timing.

The third area is the tidal Delaware River. Here, confidence is
increasing that minor flooding will occur during the afternoon,
as predecessor southeast winds will likely combine with
freshwater runoff to lead to a period of tidal flooding from
early afternoon to early evening. As with Delaware Bay,
confidence is not particularly high on exact timing of flooding,
so have issued a coastal flood advisory for a broader period of
time than normal (11 am to 8 pm).

The fourth area is the Atlantic coast. As with Delaware Bay,
timing of the strongest surge appears to occur between
astronomical high tides. However, the strength of onshore flow
and exacerbating behavior of wave runup will likely produce
areas of flooding. Of particular concern is back bays that are
susceptible to southeast flow, which can act to trap water.
Barnegat Bay and Little Assawoman Bay are particularly
susceptible in these regimes, and these areas may experience
more widespread/significant flooding. Confidence is pretty low
in general for the coast, but given the very strong onshore flow
expected today, suspect at least some impacts in the especially
vulnerable spots are likely.
