.DISCUSSION...
KEY MESSAGE 1...Patchy fog across the area could result in some
slow downs with this morning`s commute. A Dense Fog advisory
was issued for areas north and west of Philadelphia.

With recent rainfall and light winds, some patchy fog has
developed across the region. Looking at surface observations,
satellite, and traffic cameras, it does appear that areas of
dense fog have developed across the Lehigh Valley, Poconos, and
NW NJ. Ended up issuing a Dense Fog Advisory for these areas
through 8 AM as visibility as low as a quarter of a mile are
likely and currently being observed.

Further south and east towards Philadelphia, and points
south/east, fog has developed though visibilities are a bit
higher. Ended up leaving these zones out of the Dense Fog
Advisory given higher visibilities but will continue to monitor
how things trend as we get towards the morning commute.

Always have low-beams on when encountering fog and allow some
extra time for travel this morning!


KEY MESSAGE 2...The unsettled pattern continues through
Wednesday, though today will feature some improvement.

A stationary front is positioned over our area this morning and
will slowly sink southward as the day goes on. Today actually
will see some marked improvement compared to the holiday
weekend. A low chance (25-30%) of showers is in the forecast for
southern Delmarva and far South Jersey, but most of the area
should stay dry today with even some peeks of sunshine.
Temperatures should hover in the upper 70s/low 80s.

The stationary front will set up over Delmarva for tonight and
tomorrow, with a wave of low pressure moving along it. This will
result in a few more rounds of showers for the Tuesday Night and
Wednesday period, mainly for areas south of I-78. A cold front
will sweep in on Wednesday from the northwest, which will put an
end to the unsettled pattern. Rainfall amounts around a half
inch or more are expected south of Philadelphia with anywhere
from a few hundredths to a quarter of an inch expected north of
the Philadelphia metro. No significant impacts are expected with
these rounds of rain. Temperatures Wednesday should be similar
to today, hovering around 80.

Once the cold front comes through on Wednesday Night, a
transition to more tranquil and nicer weather is expected.


KEY MESSAGE 3...Drier and more seasonable conditions return for
the end of the week into the weekend.

Behind the cold front from Wednesday, we trend slightly cooler for
Thursday which continues into the weekend. High temperatures for
most locations will be in the 70s during this timeframe and lows
generally in the 50s. A high pressure system is forecast to
gradually build into the region Thursday and remain in place into
the weekend. A low pressure system is also forecast to move into the
Northeast Friday into Saturday, but model guidance trends continue
to show the high pressure system having more of an influence across
our area. Due to this high pressure system in control, it looks to
be a drier end of the week and continue into the weekend.

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

Through 12z...Tricky and uncertain forecast continues with some
patchy fog developing. Have a period of MVFR/IFR VSBYs with
fog/ground fog at times reducing visibility. Periods of some
LIFR VSBYs at KILG/KMIV/KACY are likely at times. Winds
favoring a northerly direction but primarily light/variable to
calm. Low confidence.

Today...IFR/MVFR conditions should improve at most terminals by
12z-13z with fog mixing out. Some stratus near KMIV/KACY could
linger for a bit, but thinking primarily VFR through the day at
most sites. Winds start out east/northeast around 5 kt or less,
veering and becoming southwesterly between 17z-19z around 5-10
kt. Moderate confidence.

Tonight...VFR conditions drop to MVFR/IFR with fog and stratus
developing with rain moving through late in the night. Around a
10-20% chance of LIFR conditions at KACY/KMIV with stratus
and/or dense fog. Winds out of the south/southwest 5 kt or less.
Low confidence.

Outlook...

Wednesday...Sub-VFR possible with scattered rain showers and low
clouds.

Thursday through Sunday...VFR. No significant weather.

&&

.MARINE...
Sub-SCA conditions expected through Wednesday. Seas of 2 to 4
feet. A Marine Dense Fog Advisory remains in place through 6 AM
for all marine zones, but may need to be extended. Will keep
track observations and make a decision around the time of
expiration.

Outlook...

Wednesday Night through Saturday...The conditions are
anticipated to be below Small Craft Advisory criteria.

Rip Currents...

For today, winds will shift to the east-southeast and will be
light, around 5 to 10 MPH. Wave heights continue to lower as
well. A medium period swell will continue. Given less energy in
the surf zone with lower wave heights and very light winds
through today, have elected for a LOW risk for the development
of rip currents for today.

On Wednesday, winds turn more offshore with breaking waves only
around 1 to 2 feet. A medium period 7 second well will persist.
With offshore winds and low wave heights, a LOW risk for the
development of dangerous rip currents is in place.

Ocean temperatures are mainly in the 50s to low 60s. These cold
water temperatures can quickly cause hypothermia and physical
incapacitation to anyone suddenly immersed in the water.
