Area Forecast Discussion
National Weather Service Mount Holly NJ
1220 PM EDT Sat Aug 1 2020

.SYNOPSIS...
A weak front will remain draped just to our south through the
day. The front lifts north as a warm front tonight. Another weak
cold front is expected to approach our region tomorrow night.
Meanwhile, Hurricane Isaias is expected to continue to progress
northward along the southeastern U.S. coast through the weekend,
then should accelerate northeast early next week along the Mid
Atlantic and northeastern U.S. coast. This track could bring
some impacts to our region. High pressure is expected to build
south towards our region during the later half of the week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Low pressure will move up the lower Ohio River Valley this
afternoon and it should begin to pull the warm front to our
south slowly toward our region. The leading edge of the clouds
ahead of the system was already over our region.

Marginal instability is expected to develop along the
southwestern edge of our forecast area this afternoon. As a
result, we will continue to mention a chance of a shower or
thunderstorm in northeastern Maryland. Some of the guidance is
also suggesting that an isolated shower or two may develop in
the interior of southern New Jersey.

Highs today should favor the middle and upper 80s in our region
with some spots hitting 90.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
For tonight, an upper level trough will be organizing to our
west helping to lift a weak surface low northward into the Great
Lakes region. This will push a warm front through the area.
Along and ahead of this feature expect some showers and storms
to move through...mainly near and after midnight. PWATs will be
rising to 2+ inches once again along with a deep warm cloud
layer so any storms will be capable of producing very heavy
rainfall. So expect there will be the potential for urban and
small stream type flooding issues. The best chances for this
look to be over eastern PA. Dew points will be on the rise as
well so it will be a warm, muggy night with lows mostly in the
upper 60s to low 70s.

For Sunday, the warm front lifts north of the area through the
morning bringing this first round of convection to an end. It
will be hot and humid as the area breaks into the warm sector
with peak heat indices potentially reaching or just exceeding
100 degrees especially over interior portions of Delmarva and
southern NJ. This will also result in significant instability
with ML CAPES progged to reach 2000-3000+ j/kg. Shear also looks
to be fairly decent as well...especially in the 0-3 km layer
with values around 30 knots. A cold front slowly approaching
from the west along with diurnal processes look to help trigger
storms by later Sunday afternoon. These will likely initiate
near or just west of the Lehigh Valley into the southern Poconos
and then move farther east into the CWA. Given the expected set
of very high instability along with modest shear, there will be
the potential once again for severe weather. Damaging winds
look to be the biggest threat. Also, given the continuing very
high PWATs (2+ inches) localized flash flooding will be possible
as well.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Summary: The main story of the long term remains Isaias and the
potential impacts it could bring to our region, primarily in
the Monday night through Wednesday morning time frame. Towards
the end of the week, tranquil weather may return with high
pressure building down from the north, at least briefly. Isaias
is currently a hurricane, but is forecast to be a tropical storm
as it approaches our region. For the latest information on the
track, intensity, and timing of Isaias, please see the NHC
forecast discussion.

Details:

Sunday night...A weak cold front is expected to approach the
region, potentially resulting in another round of showers and
thunderstorms Sunday night, though with the timing, instability
will be limited so convection may be dissipating as it
approaches the region. It is expected to be a weak temperature
gradient, so low temperatures will remain well above normal,
mostly in the 70s (with the exception of the higher terrain of
the southern Poconos.

Monday...Depending on how quickly an upper level southwesterly
jet develops, another round of showers and thunderstorms is
likely Monday afternoon ahead of any of the outer rain bands
associated with Isaias. It seems like most guidance is backing
off the most progressive solutions of Isaias, so it seems
unlikely that we will see any direct impacts from Isaias during
the day on Monday. However, a combination of the upper level jet
and high cirrus clouds ahead of Isaias should result in mostly
cloudy conditions through the day. That will help to keep our
temperatures near normal for a change, with highs mostly in the
mid to upper 80s.

Monday night through Tuesday night...The only change with this
forecast is that the mention of likely rain was expanded further
west to account for the current forecast track. As for the
impacts, it still appears that the main impact for most of the
region will be heavy rain. As is often the case with tropical
systems, model soundings depict precipitable water values well
above normal and a deep warm cloud layer, increasing the risk
for heavy rain. Details like where the axis of heaviest rain
will be and how much rain we will see are still uncertain.
Interestingly, recent trends with this storm indicate the rain
shield could be very asymmetrical, favoring the eastern side of
the storm. If that continues to hold true, then the heavy rain
threat may shift to be primarily along the coast.

As for the wind impacts, at this point, it looks like the
threat for tropical storm force conditions is mostly for the
coastal plains, but this will be highly dependent not only on
the track as it passes closest to our region, but also upstream.

Wednesday...By most guidance, Isaias should be accelerating
away from our region by Wednesday morning. If this holds, we may
have little in the way of rain after mid day Wednesday.
However, given the uncertainty we've seen with this system,
stayed close to the previous forecast for chances of rain
through the day.

Thursday and Friday... In the wake of Isaias, and the mid and
upper level low which should finally start lifting away from the
Great Lakes region through this period, high pressure is
expected to build in, bringing a return to tranquil conditions.
How long that will last is still uncertain though as some
operational models depict a warm front impinging on the surface
high as early as Friday morning, which could bring another round
of rain.

&&

.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

This afternoon...VFR. Variable wind 6 knots or less, becoming
southeast to south 5 to 10 knots. High confidence.

Tonight...Conditions expected to lower to at least MVFR as some
showers and storms move through. Local IFR conditions will be
possible as well. Winds mainly southeast around 5 knots. Low
confidence on how widespread any storms will be as well as if
IFR conditions will occur. Otherwise moderate confidence.

Outlook...

Sunday...Becoming VFR with SW winds 10-15 gusting up to 20
knots. Late day, the eastern PA sites could be affected by more
showers and storms bringing brief restrictions to sub-VFR
conditions.

Monday through Wednesday...Periods of MVFR or even IFR
conditions with rain and some thunderstorms. Southwest to
southeast winds 5-10 knots. However, expect shifts and
increasing winds as Isaias passes close to our region on
Tuesday, especially along the coast including KACY. A shift to
northeasterly then northwesterly is possible near the storm. As
the storm moves away on Wednesday, winds should once again be
southwesterly and light (less than 10 kt). Low confidence
especially with details of timing of lower conditions and winds.

&&

.MARINE...
A northeast wind around 10 knots is forecast to veer to the
southeast through the day. Wave heights on our ocean waters are
expected to range from 2 to 4 feet. Waves on Delaware Bay
should be 2 feet or less.

Little change is expected for tonight however by later Sunday
both winds and seas will be increasing to near low end SCA
conditions.

Outlook...
Monday through Wednesday...The details will depend on the track
and intensity of Hurricane Isaias as it tracks north and
northeastward. Hazardous seas and winds look probable, however
the specific details remain uncertain at this time including the
timing.

Rip Currents...
A moderate risk of rip currents is forecast for this afternoon
due to a long period swell.

For Sunday, the surf height will be increasing however the
period should be shorter. For this reason, we continue a
moderate risk.

A significant increase in rip current potential is likely into
early next week as Hurricane Isaias tracks near the East Coast.

&&

.TIDES/COASTAL FLOODING...
For areas along the southern New Jersey and Delaware Atlantic
coasts, as well as areas along Delaware Bay, some spotty minor
flooding is possible again with the high tide this evening. At
this point there remains considerable uncertainty with the track
and timing of Isaias, and thus the ultimate impacts it may have
on tide levels primarily Tuesday into Wednesday.

&&

.EQUIPMENT...
The NOAA Weather Radio All-Hazards broadcast from Hibernia
Park, Pennsylvania (Station WNG-704) remains off the air, but
repairs are anticipated soon.
