Area Forecast Discussion
National Weather Service Mount Holly NJ
352 PM EDT Sat Jun 9 2018

.SYNOPSIS...
A stalled boundary will remain across part of the area through the
weekend. Several waves of low pressure will track along the boundary
through Monday. High pressure over eastern Canada will build
southward into the Mid Atlantic states on Monday, moving offshore
Monday night into Tuesday. A cold front will cross the region on
Wednesday. High pressure will return for Thursday. Another low
pressure system will affect the region towards the end of the
work week.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
Our region remains on the southwestern periphery of an upper-level
trough which is centered near the Canadian Maritimes. There are
several short waves traversing the flow. The forcing however over
our area is weak this afternoon, with the convection mostly driven
by heating, boundary interaction, cold pool development and weak
convergence. A secondary front is forecast to drop south-
southeastward into our area through tonight.

The ongoing convection across our southern zones is expected to
weaken and mostly dissipate through early this evening as cold pools
allow for the cores to rain themselves out. In addition, forcing is
weak and thus the convection should be primarily diurnally driven.
The convection is embedded in weaker flow and therefore training and
backbuilding has been common. The convection is tending to be more
pulse driven given low shear, thus locally strong to damaging winds
gusts and some hail may occur into early this evening with the
stronger cores. The precipitable water values are near 1.8 inches
and the convection is very efficient rainfall producers. This
combined with slow storm motions, cell mergers and backbuilding has
resulted in some flash flooding. The GOES-East visible satellite
imagery this afternoon shows an MCV moving across northern Indiana.
A weaker perturbation looks to be in eastern Ohio and western
Pennsylvania, and this feature may allow for some showers/thunder
overnight especially for the western and southern areas. There is
low confidence in the shower/thunder threat after early this evening
given timing and forcing uncertainty pertaining to the short waves
and any weak embedded MCV.

The airmass will remain humid south of a surface front through
tonight, and this may result in some low clouds developing
especially across southern New Jersey and Delmarva where convection
occurred this afternoon. In addition, local fog should develop
especially in these same areas. Low temperatures are mostly a multi-
model/continuity blend. The hourly temperature, dew point and wind
grids are a blend of continuity and guidance, including some high-
res models to hopefully help with local/convective effects.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...
Our sensible weather may end up being complex during Sunday. As we
look aloft, a trough is forecast to amplify some across the
Northeast and northern Mid-Atlantic region through the day. This
will allow continued short wave energy to traverse the region. A
frontal zone should be stalled somewhere across our southern zones
and this may yet again result in some showers and thunderstorms. The
instability should be less given a northeasterly low-level flow that
is forecast.

The complicating factor involves MCV's that were generated from
convection well to our west. The model guidance looks to be focusing
on one main short wave that arrives around midday. Looking at the
guidance and tracing back this short wave, it looks to be tied to
the current MCV in northern Indiana. It is during this time frame
where a more organized area of showers and thunder arrives from the
west, with the better chance of convection farther south closer to
better instability. The northern extent of this may be overdone
given more stable air and also drier air. The timing is a little
less certain and therefore our PoP forecast is as well. The
precipitable water values are forecast to be 1.50-1.75 inches (lower
across the far northern areas), therefore locally heavy rain could
result in localized flooding although convection should not be as
robust as what occurred today (Saturday). Overall, lots of clouds
are expected to be around and with more of a northeast wind north of
the surface front it will be cooler across the region. High
temperatures are a blend of continuity and guidance which resulted
in cooler numbers.

&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
Unsettled weather continues into the start of the new week, and
the primary focus will be over the Delmarva.

A stationary boundary remains along the Mid-Atlantic into the
new week. For Sunday night, PWATs will increase to 1.75-2.0"
across eastern Maryland, Delaware, and southern New Jersey due
to persistent onshore flow. ML MUCAPEs will range from 500-1000
J/kg across the Delmarva, so a few embedded thunderstorms are
possible. Heavy rain is becoming likely, and this could lead to
flash flooding across the Delmarva and southern New Jersey.

Rain tapers off Monday morning as the low moves offshore.

During the day Monday, high pressure over eastern Canada builds
south into the Northeast, and then moves into the Gulf of Maine
late in the day and Monday evening. Conditions gradually dry out
from north to south, but some additional showers are possible
across the Delmarva.

High pressure moves out to sea on Tuesday, and then another area
of low pressure slides along the stationary boundary, possibly
bringing more showers with it.

A cold front approaches Tuesday night and moves through the
region Wednesday. Conditions may dry out for Thursday, but
another area of low pressure may affect the region late in the
week.

&&

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

Rest of this afternoon...VFR, except IFR at times at ACY and MIV due
to showers and thunderstorms. The showers and thunderstorms are
anticipated to remain south of PHL. A rain cooled boundary shifting
inland may enhance a southeast wind for a time at PHL, PNE to TTN
late this afternoon. Northeast to southeast winds 5-8 knots.

Tonight...MVFR/IFR conditions possible early at MIV and ACY due to
showers and thunderstorms in the vicinity, otherwise VFR through at
least this evening. MVFR ceilings and/or visibilities may develop
overnight especially from near PHL on southward. Winds becoming east
and northeast at 5 knots or less. Low confidence with the timing and
extent of the MVFR or lower conditions overnight.

Sunday...Areas of MVFR/IFR conditions may linger at ILG, MIV and ACY
for much of the day, otherwise mostly VFR. Some showers and possible
thunderstorms may occur from about RDG to PHL to ACY southward
especially by late afternoon. Northeast winds near 10 knots.

OUTLOOK...
Sunday night-Monday morning...Showers, heavy rain possible at
times, and scattered thunderstorms possible for southern
terminals, and scattered showers for northern terminals.

Tuesday-Wednesday...Generally VFR, but scattered showers
possible.

&&

.MARINE...
The conditions should remain below Small Craft Advisory criteria
through Sunday. A frontal boundary stalled in the area should settle
south a bit then another front arrives later tonight into Sunday.
This will result in any southerly winds becoming northeast,
especially during Sunday when some increase is expected from north
to south. Some showers and thunderstorms into this evening mainly
from Atlantic City southward will produce locally gusty winds.

OUTLOOK...
Sunday night...SCA conditions possible on southern ocean
waters. Showers and scattered thunderstorms with heavy rain
possible, especially Sunday night.

Monday...Pressure gradient tightens. SCA conditions possible for
southern ocean waters and DE Bay.

Monday night...SCA conditions diminish Monday night.

Tuesday-Wednesday...Sub-SCA conditions.

RIP CURRENTS...
A low risk of rip currents continues into this evening as seas are
2-3 feet with a period of 4 to 8 seconds.

For Sunday, the rip current risk may increase to moderate as
northeasterly flow, seas and wave period increase some.
