Synopsis
High pressure located in eastern ontario and southern quebec
this afternoon will continue to build to the south and east. The
air mass should continue to influence our weather into Tuesday.

A cold front is anticipated to approach from the west on
Wednesday and it is expected to pass through our region on
Thursday. A secondary cold front may arrive on Saturday.

Near term until 6 am Sunday morning
Northeasterly winds Saturday afternoon gusted over 20 mph close
to the coast, and up to 15 mph further inland. As mixing ends
around sunset, and as the surface pressure gradient relaxes just
a bit, wind speeds are expected to settle in the 5 to 10 mph
range through the overnight hours. However, the onshore flow is
expected to continue as high pressure centered over eastern
canada continues its slow eastward migration. Models suggest
light precipitation will eventually start falling over the near-
coastal locations of the cwa, as the lower portions of the
atmosphere become saturated, but this could be more of an
indication of low clouds, especially toward morning. If
precipitation does indeed develop, the coastal sections are the
most susceptible, with lower chances further and further inland.

Will introduce low chc pops closer to the coast, then slight
chc pops toward the philadelphia metro area. Adjustments may be
needed as the event unfolds. With air moving in from the ocean,
temperatures during the overnight hours are expected to dip into
the low 50s in the north, and in the low 60s south where a
cloud cover is expected to inhibit radiational cooling.

Short term 6 am Sunday morning through 6 pm Sunday
High pressure centered over nova scotia will continue its slow
eastward trek even as low pressure (with some tropical
influence), rides northeast along, then away from, the east
coast along a nearly stationary front just to our south.

Depending on the relative strength of these two systems, the
onshore flow may veer more to the east versus northeast. Wind
speeds will pick up again too, with gusts in the 15 to 20 mph
range possible, and even stronger toward the coast. Models
continue to indicate light precipitation (drizzle?) possible
into the delaware valley, but this may be too aggressive. Will
keep the higher pops closer to the coast, lower pops further
inland. High temperatures on Sunday are not expected to emerge
from the 70s, and any precipitation may make it cooler.

Long term Sunday night through Saturday
The axis of a high pressure ridge is forecast to remain to the
lee of the appalachians for Monday and Tuesday. The pattern will
maintain a northeast to east surface wind in our region. The
onshore flow creates a bit of uncertainty in determining the
amount of cloud cover and the potential for some light rain or
drizzle. Regardless, most of the period from Sunday night
through Tuesday should be precipitation-free and there will
likely be at least partial clearing at times. The early autumn
temperature preview is forecast to continue with daytime highs
in the 70s and lower 80s, and overnight lows in the 50s and
lower 60s.

The surface ridge is anticipated to lose its influence over our
weather on Tuesday night and Wednesday as a cold front
approaches from the west. The front is expected to arrive in our
region on Wednesday night before passing off the coast on
Thursday. We will mention a chance of showers and thunderstorms
for Wednesday and Wednesday night with some clearing in the
forecast for Thursday. Temperatures will likely return to more
typical readings for late august.

A mid level trough is expected to begin settling over the great
lakes and the northeastern states for the late week period into
the holiday weekend. A secondary cold front may arrive around
Saturday. However, moisture is forecast to be rather limited so
we are anticipating fair weather for Thursday, Friday and
Saturday.

Aviation 20z Saturday through Thursday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Tonight..MainlyVFR. Lowering clouds expected near the shore.

MVFR conditions or lower possible (acy miv)if light rain and or
drizzle forms toward morning. NE to E winds 5 to 10 knots.

Sunday...VFR to MVFR conditions expected at the inland taf
sites, but ifr conditions possible at miv and acy with low
clouds and possible light rain drizzle. E winds gusting up to 20
kt near the coast, and 10 to 15 kt inland.

Outlook...

Sunday night and Monday...VFR and MVFR ceilings are expected.

Northeast wind 6 to 12 knots.

Monday night and Tuesday... MainlyVFR. Northeast to east wind 5
to 10 knots.

Tuesday night... MainlyVFR. Variable wind 6 knots or less.

Wednesday... MainlyVFR. A chance of showers and thunderstorms.

South to southwest wind 5 to 10 knots.

Wednesday night... MainlyVFR. A chance of showers and
thunderstorms. Southwest to west wind 5 to 10 knots.

Thursday... MainlyVFR. West to northwest wind 5 to 10 knots.

Marine
Winds and seas touched SCA conditions at a few buoys this
afternoon. While winds may improve slightly overnight, a
persistent onshore flow should keep seas in the 5 foot range
along the coast. Then as winds pick up again on Sunday, seas and
winds are expected in the SCA range, both on the ocean and bay.

A SCA has therefore been hoisted for the ocean starting 6pm
this evening, and for the bay starting 6 am Sunday.

Outlook...

Sunday night and Monday... A small craft advisory is in effect
for a northeast wind 15 to 25 knots with gusts up to 30 knots.

Wave heights on our ocean waters will likely build to 5 to 8
feet.

Monday night... Northeast wind 10 to 20 knots with gusts up to
25 knots. Waves on our ocean waters are expected to be 5 to 7
feet.

Tuesday... Northeast wind 10 to 15 knots with gusts up to 20
knots. Waves on our ocean waters are expected to be 4 to 6 feet.

Tuesday night... Northeast wind 10 to 15 knots. Waves on our
ocean waters are expected to be 4 to 5 feet.

Wednesday through Thursday... No marine headlines are
anticipated.

Rip currents...

northeasterly winds in the 15 to 25 mph range and seas between
4 and 5 feet will result in a moderate risk of rip currents on
Sunday.

This elevated rip current risk (either moderate or at times
high) is expected to persist until at least Tuesday as a
prolonged period of onshore flow and elevated seas looks likely.

Tides coastal flooding
A prolonged period of northeast to east flow will continue
through at least Tuesday. This persistent onshore fetch,
combined with increasing astronomical tides due to an
approaching new moon on Thursday, will likely lead to increasing
coastal water levels. Minor coastal flooding is possible
starting Sunday night over delaware bay and portions of the nj
shore. The better chances for minor coastal flooding are on
Monday and Tuesday.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... Small craft advisory until 6 pm edt Monday for anz450>455.

Small craft advisory from 6 am Sunday to 6 pm edt Monday for
anz430-431.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
