.KEY MESSAGES...
1. Dry conditions expected through much of tonight, however a
few isolated showers or storms may arrive by around dawn
Wednesday.

2. Dangerous heat is likely on Thursday and Friday.

3. There are multiple chances for thunderstorms Wednesday through
Friday. The weekend has trended drier.

.DISCUSSION...
KEY MESSAGE 1...Dry conditions expected through much of
tonight, however a few isolated showers or storms may arrive by
around dawn Wednesday.

Broad upper ridging will build through tonight. At the surface,
high pressure is sliding offshore, beginning a transition to a
warm advection regime which will ramp up late tonight as a warm
front lifts north. A mid level shortwave trough associated with
upstream convection will approach the area by dawn Wednesday.

Following a warmer afternoon, lows tonight will be upward of
10-15 degrees warmer than this morning was, mainly in the mid
50s to mid 60s under increasing cloud cover. We'll have to keep
an eye on the remnant convection approaching from upstream
overnight. Current indications remain that instability will
weaken considerably toward the east as the remnant activity
moves in overnight into our area. This will likely result in
some isolated decaying showers and embedded rumbles of thunder
moving in around dawn or so across the western half of the
forecast area.

KEY MESSAGE 2...Dangerous heat is likely on Thursday and Friday.

In general, mid-level ridging is expected to build into the region
during the middle and latter part of the week. However, guidance has
been trending southward with placement of an upper-low over Canada
and associated troughing over the CONUS, and therefore featuring a
slightly weaker ridge axis through our region. At the surface, the
region will largely be under the influence of high pressure centered
over portions of the Southeast.

Despite this, dangerous heat is still expected across the area on
Thursday and Friday. Temperatures on both days look to climb into
the low to mid 90s across most of the area. With dewpoints generally
in the low 70s, heat indices are expected to range between 95 to 104
degrees across the majority of the area, outside of the Poconos. The
greatest threat for heat indicies over 100 will be found across
southeast PA, southern NJ and the Delmarva. This level of heat and
humidity can become dangerous quickly for sensitive individuals and
those outdoors for extended periods of time. Heat headlines will
likely be necessary during this time period to cover this threat.

A cold front is forecast to move through the region late Friday into
Saturday, which will is expected to knock temperatures and dewpoints
down several degrees. Though it will still be hot with highs upper
80s to low 90s over the weekend, dewpoints will return to more
comfortable levels, minimizing the threat for additional heat
headlines.

KEY MESSAGE 3...There are multiple chances for thunderstorms
Wednesday through Friday, some which may be severe. The weekend has
trended drier.

The pattern in place will become increasingly conducive for
precipitation chances across the region beginning on Wednesday. Much
of this activity looks to be in the form of diurnally driven
convection, though some guidance is beginning to indicate a few
better opportunities, especially on Friday.

The first opportunity comes on Wednesday, with a weak shortwave and
surface trough moving through the region. Given marginal instability
and shear around the region, the Storm Prediction Center now has our
entire forecast area in a MARGINAL Risk (Level 1/5) for severe
weather. As of right now, PoPs are around 40-60% areawide. The next
opportunity comes on Thursday, however large scale forcing and shear
are expected to remain weak. However, hot temperatures and high
dewpoints will likely trigger at least some diurnally driven
convection, so the Storm Prediction Center has the entire region in
a MARGINAL risk once again. PoPs are generally in the 30-60% range.

On Friday, the region is expected to begin feeling the influence of
the upper trough to the west of the region, in addition to a cold
front that will be approaching from the west. Scattered showers and
storms may focus near and ahead of this boundary, and with strong
destabilization and slightly better wind fields aloft, there is
concern that some severe threat could materialize. This will need to
be monitored in the coming days as the SPC now has areas northwest
of the I-95 corridor outlooked in a 15% chance of severe weather
area.

Guidance has trended considerably drier for much of the weekend in
wake of the cold front, so it now appears that much of the weekend
will be dry. However, another front may approach towards the end of
the weekend and into early next week, with more chances of showers
and storms returning next week.

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Tonight...Generally a VFR forecast. A few SHRA may develop after
06Z, but restrictions will be minimal, generally MVFR, and
confidence is low that any given SHRA will pass over any given
terminal. Will carry VCSH for all but KMIV/KACY. S to SW winds 5
to 10 kt, diminishing to around 5 kt. Low confidence on timing
and restrictions with any SHRA.

Wednesday...VFR initially. MVFR CIGs develop from west to east
starting right after 12Z for KRDG/KABE, and MVFR CIGs spread to
KTTN/KPNE/KPHL/KILG. KMIV/KACY CIGs should remain VFR outside of
any SHRA. One wave of SHRA may impact KRDG/KABE/KTTN/KPNE/KPHL
and KILG in the morning, and will carry PROB30 groups for those
terminals for potential SHRA. A round of TSRA may then impact
the terminals in the afternoon, and will PROB30 groups for that.
S to SW winds 5 to 10 kt in the morning, increasing to 10 to 15
kt with gusts up to 20 kt in the afternoon. Low confidence on
timing and restrictions resulting from any SHRA and TSRA.

Outlook...

Wednesday night through Friday night...Prevailing VFR expected
through the period. Brief periods of sub-VFR conditions are
possible, with isolated to scattered showers and thunderstorms
during the afternoon and evening hours.

Saturday through Sunday...VFR. No significant weather expected.

&&

.MARINE...
No marine hazards expected through Wednesday. Southerly winds
increasing to 10-15 kts with gusts up to 20 kts and seas 2-3
feet. May try to touch SCA gusts on the waters late Wednesday,
but confidence is low at this time.

Outlook...

Wednesday night...SCA conditions possible due to wind gusts up to 25
kt and seas around 3-5 feet.

Thursday through Sunday...No marine headlines anticipated. Winds
will generally remain between 5-15 kt through Saturday, with gusts
up to 20 kt possible on Sunday. Seas generally around 2-3 feet.
Isolated to scattered showers and thunderstorms possible on Thursday
and Friday. Fair weather expected for Saturday and Sunday.

Rip Currents...

For Wednesday, southerly winds increase to 10 to 20 mph with
gusts up to 25 mph, especially in the afternoon. Breaking waves
will vary between 2 to 3 feet. While there will be a light
easterly swell in the morning, a more dominant southerly swell
around 7 to 8 seconds should propagate northward in the
afternoon. Given these conditions, have opted to go with a
MODERATE risk for the development of dangerous rip currents for
all beaches.

For Thursday, southwesterly winds diminish to around 10 to 15
mph. Breaking waves around 1 to 2 feet with a southerly swell
around 6 to 7 seconds. Given the lighter conditions, have opted
to go with a LOW risk for the development of dangerous rip
currents for all beaches.

Ocean water temperatures are gradually increasing, but remain
mostly in the 60s.
