.DISCUSSION...
KEY MESSAGE 1...A strong cold front passing through the region
late tonight into early Friday morning will bring showers with
beneficial rainfall and breezy conditions.

Modest southwest flow ahead of tonight`s cold front will yield
warm temperatures this afternoon into tonight. Highs this
afternoon in the mid 70s for most areas, with southwest winds
gusting 20-30 mph into tonight ahead of the front. Temperatures
will remain in the 60s overnight until frontal passage.

Showers will begin to spread into the area from north to south
late this evening and into the overnight period. While a stray
shower cannot be ruled out as far south as the Philly metro this
evening, most areas will likely not experience rain until after
midnight (prior to midnight near/north of I-78). Some rumbles of
thunder and brief downpours will be possible overnight, however
severe thunderstorms are not expected.

The frontal system will continue pushing south and clear our
Delmarva zones by mid morning. The showers will also continue
spreading south, where rainfall for our far southern NJ and
Delmarva counties will be focused mainly during the daytime
Friday. Periods of rain will continue off and on through the day
for these areas. Farther north, especially near and northwest of
I-95, conditions will dry out be midday under mostly cloudy
skies.

Generally expecting around 0.25-0.50" of rainfall across the
board through Friday, with localized amounts up to 1" possible.
Long story short, a beneficial rainfall event for our area.

Winds will shift northerly behind the front and remain breezy,
with gusts 20-30 mph gradually diminishing into the afternoon.
Temperatures will fall to near 50 degrees behind the front, and
remain steady during the daytime Friday. Temperatures then
falling into the mid 20s to low 30s Friday night into Saturday
morning.

KEY MESSAGE 2...Mild and unsettled pattern takes hold as early
as Monday Night next week.

Cool high pressure that dominates this weekend resulting in dry
and quiet weather will move offshore on Sunday. Return flow
sets up, ushering in a warmer airmass after below normal
temperatures on Saturday, and near normal temperatures on
Sunday. Warm south/southwesterly flow for the beginning and
middle part of next week will result in a stretch of above
normal temperatures for the early and middle portion of next
week.

While it will be on the more mild and warmer side next week,
there will be multiple chances for rain as several frontal
systems slide by. None of these systems look overly impactful at
this point, but there could be some periods of rain, beginning
late Monday and continuing off and on through the middle of the
week.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Through 00Z...VFR. Southwest winds 10-15 kts gusting up to 25
kts. High confidence.

Tonight...VFR conditions will prevail for most of the night,
however scattered showers may briefly result in MVFR conditions,
especially after 06Z. LLWS ahead of a cold frontal passage
between 07-12Z, then a period of MVFR conditions and steadier
rainfall likely following FROPA. A low chance (10-20%) of brief
thunder, but probability is too low to include a TAF mention.
Southwest winds 10-15 kts prior to FROPA, with some occasional
gusts up to 25 kts, then shifting northerly following FROPA.
High confidence in general progression of conditions, but lower
confidence on details of exact timing.

Friday...Some MVFR ceilings possible early (especially at
MIV/ACY), then VFR conditions should prevail. Periods of light
rain linger for MIV/ACY much of the day, but conditions should
be mainly VFR after 15Z. Northerly winds 10-15 kts, gusting up
to 25 kts early, then winds diminishing after 18Z. High
confidence overall.

Outlook...

Friday night...VFR. North to northwest winds 5-10 kts, with
some gusts up to 20 kts possible late.

Saturday...VFR. Northwest wind gusts between 20-25 kt.

Saturday night through Monday...VFR. No significant weather.

&&

.MARINE...
South to southwest winds 15-25 kts with gusts up to 30 kts will
continue through tonight. Winds increase across Delaware Bay
tonight. A cold front will pass offshore early Friday morning,

to 20 kts on Friday. Seas 4-6 feet across the Atlantic waters
through Friday morning.

A Small Craft Advisory is now in effect through noon Friday for
the Atlantic waters. The Small Craft Advisory remains in effect
for Delaware Bay for tonight.

Outlook...

Friday night through Saturday...Advisory conditions expected as
wind gusts 25-30 kt pick up after a cold front moves through
late Friday Night. Gusts continue through Saturday afternoon.
Seas could near 5 feet at times.

Saturday night through Sunday night...No marine hazards
expected.

Monday...Advisory conditions likely (60-70%) as winds pick up
