.SYNOPSIS...
A cold front slowly works its way through the region today
through tonight, then one area of low pressure passes north and
west of the region while a coastal low passes east of the region
tonight through Saturday. High pressure briefly builds in from
the north late Saturday through Sunday. Low pressure passing
west of the area pulls a warm front through the region Sunday
night through Monday. A cold front passes through the region
Tuesday. High pressure returns for Wednesday and Thursday.

&&

.NEAR TERM /THROUGH TONIGHT/...
A cold front slowly approaches from the west today and works
its way through the region tonight.

Most of the area will be dry for most of the day today, and it
will be another warm and moderately humid day for early June
with highs in the mid and upper 80s and surface dew points in
the mid and upper 60s.

Low pressure on that cold front lifts through central
Pennsylvania and central New York starting this afternoon.
Showers and scattered thunderstorms will develop over the
southern Poconos and Lehigh Valley during this time. SB CAPE
Values will be over 1500 J/kg along with 20 to 25 kt of 0-6 km
Bulk Shear. The Storm Prediction Center has a Marginal Risk (1
out of 5) for severe weather today with damaging winds being the
primary threat. In addition, PWATs will be in excess of 1.5
inches, and heavy rain in the northern areas could result in
localized flooding.

Some showers and scattered thunderstorms may make it down to
the I-95 corridor by this evening, but the front will mostly be
hung up west of the area. Lingering showers and thunderstorms
will impact areas north and west of the I-95 corridor through
tonight. Otherwise, another warm and humid night on tap with low
stratus and patchy fog. Lows will be in the 60s.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Unsettled weather remains on tap for the weekend.

Weak low pressure on the cold front just west of the area
approaches Saturday morning and works its way through the region
during the day Saturday, finally departing in the afternoon.
Showers become likely with scattered thunderstorms across the
region. Cloudy skies and rainfall will knock temperatures down
on Saturday compared to Friday, with highs generally in the
upper 70s to low 80s, yet dew points remain in the upper 60s. SB
CAPE values will be a touch lower on Saturday, generally 1000
to 1500 J/kg, but 0-6 KM Bulk Shear will be a touch higher on
Saturday, generally 25 to 35 kt. The Storm Prediction Center has
a Marginal Risk (1 out of 5) for Delmarva, central and southern
New Jersey, and most of southeast Pennsylvania for Saturday
with damaging winds being the primary threat.

Showers and thunderstorms taper off late in the day and by
Saturday evening. High pressure noses in from the north, but
there will not be much cooler and drier air associated with it.
Dew points drop into the lower 60s, and lows Saturday night will
be in the lower 60s as well.

The base of high pressure lifts through the region Sunday
morning. Another area of low pressure begins to organize and
develop west of the area, and a warm front will extend out from
that low. This warm front lifts to the north and west through
Delmarva and the Delaware Valley, and then another round of
showers and thunderstorms will develop by Sunday afternoon.
Highs will generally be in the mid to upper 70s.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
Active weather on tap for the first half of the Long Term
period. Low pressure lifts through the region Sunday night
through Monday morning with yet another round of convection.
Conditions briefly dry out Monday afternoon and evening, and
then another cold front approaches from the west on Tuesday,
crossing the area Tuesday night through Wednesday morning.
Showers and thunderstorms will affect the area during this time,
with likely PoPs (around 70 percent) on Tuesday.

High pressure builds in from the west on Wednesday and
conditions finally dry out through Thursday. Highs will top off
in the 70s to around 80 on Wednesday, and then will be in the
80s on Thursday.

.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Early this morning...VFR overall, but brief MVFR or even IFR
CIGs possible at KMIV and KACY from 08Z through 12Z. Will carry
TEMPO groups for those sites for BKN025 at KMIV and BKN010 at
KACY. Light S to SW winds, but LGT/VRB at most terminals. High
confidence for all but KMIV/KACY, as low confidence on stratus
development at those terminals.

Today...VFR. Scattered SHRA possible, mainly at KRDG/KABE prior
to 00Z. Will carry VCSH at those terminals and will keep the
rest of the terminals dry. S to SW winds 5 to 10 kt. Moderate
confidence overall.

Tonight...SHRA with scattered TSRA mostly at KRDG/KABE, but
some SHRA may make it down to the I-95 corridor terminals. MVFR
CIGs possible after 06Z Saturday. Light S winds. Low confidence.

Outlook...

Saturday through Saturday night...Sub-VFR conditions likely in
SHRA/TSRA during the day, then sub-VFR conditions in fog and
stratus possible at night.

Sunday through Sunday night...VFR initially Sunday, then sub-
VFR in SHRA/TSRA Sunday afternoon and Sunday night.

Monday through Tuesday...VFR Monday afternoon, then sub-VFR in
SHRA/TSRA Monday night and Tuesday.

.MARINE...
Sub-Small Craft Advisory conditions today and tonight. South to
southwest winds 10 to 15 kt today become south to southeast
around 10 kt tonight with 3 to 4 ft seas.

Friday night through Saturday night...Sub-SCA conditions. VSBY
restrictions in showers and thunderstorms, mostly on Saturday.
Thunderstorms may result in locally higher winds and waves. VSBY
restrictions in fog possible at night.

Sunday through Monday...Sub-SCA conditions. VSBY restrictions

Rip Currents...

There is a LOW risk for the development of dangerous and life
threatening rip currents for the Jersey Shore and Delaware
Beaches for Friday and a MODERATE risk for Saturday. For
Friday, winds will be south to southeast around 5 to 10 mph
with breaking waves around 1-2 feet with a period of 7-8
seconds. On Saturday, there is currently a MODERATE risk but
this may increase to a HIGH risk with a future update as
conditions look favorable for a potentially high rip current
risk. Winds on Saturday are around 5-10 mph out of the southwest
to west-southwest with breaking waves of 1-2 feet with upwards
of 3-4 feet at times for parts of New Jersey.
