Synopsis
A low pressure system will pass to the south and east of the
area tonight, followed by weak high pressure for Wednesday. Another
system develops over the ohio valley affecting the area late
Wednesday through early Friday. Weak high pressure returns for
Saturday with yet another low pressure forecast to affect the region
for Sunday or Monday.

Near term /until 6 pm this evening/
A low is expected to slide northeast along the now stationary front
which is stalled well off shore. Models have trended later and
further southeast with the track of this low. As a result, adjusted
pops down through the morning hours, and along and west of the i95
corridor. As mentioned by the previous shift, it doesn't look like
there will be enough instability to support thunderstorms. Thus,
expect only showers through the day today.

As for temperatures, there may be a slight warming trend as compared
to yesterday, but thanks to onshore flow, and increasing cloud cover
late in the day, expect to remain slightly below normal.

Short term /6 pm this evening through 6 am Wednesday/
Low will continue to slide northeast, with lingering showers
possible, especially through the evening hours. A mid level short
wave ridge is expected to build over the ridge beginning late
tonight though. The associated subsidence should help to bring a
quick end to the precipitation after midnight.

Long term /Wednesday through Monday/
Wednesday... The coastal low remains to the south and east of our
area and pushes to the northeast fairly quickly. We dry out through
Wednesday and rain looks to hold off for much of the day as weak
high pressure cross the area.

Wednesday night and Thursday... Low pressure over the ohio valley
will move northeast on Thursday. Another low forms along the cold
frontal boundary as it nears our area, and will cross our area later
Thursday.

Rain will start to overspread the region late Wednesday night and
continue through much of Thursday. Marginal instability is noted and
we continue to mention the chance for convection across the area.

With pwat's once again rising up around 1.5-1.7 inches, we have the
potential for moderate to heavy rain. With the wet period we have
had of late, we will need to continue to monitor any heavy rain
threat.

Friday... Some showers possible Friday, mainly early and across the
northern half of our forecast area. Overall, it should start to
clear out across our area. Although, a slight cool down can be
expected in the westerly flow.

Saturday... High pressure will build in for Saturday and it should be
a great start to the holiday weekend. A shortwave moves through the
mid levels and across our area Saturday afternoon/evening. This may
spark off a few light showers, mainly across the northern areas.

Sunday and Monday... The rest of the holiday weekend looks unsettled
as another low pressure system develops and heads towards the mid-
atlantic. A chance for some showers and/or thunderstorms will be
possible. A cooler day on Sunday with highs only into the low to mid-
70s but warming is expected for Monday, with highs into the upper
70s to lower 80s.

Aviation /08z Tuesday through Saturday/
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Some low clouds continue to linger across the coastal plains and
shallow ground fog has developed at some of the TAF sites in the
wake of the cold front earlier. Expect this to continue at times
through sunrise. After 12z, should see several hours at least ofVFR
conditions across the region. After 18z, could see low clouds and
showers move in from the south. At this time, kilg, kmiv, and kacy
are at the highest risk to see conditions drop belowVFR (though it
is also possible at kphl, kttn, and kpne).

Winds will be gradually shifting through the day from northerly to
easterly, before shifting back to northeasterly tonight, but wind
speeds are expected to generally remain at or below 10 kt.

Outlook...

Wednesday...VFR conditions expected early. MVFR/ifr conditions
early, mainly at kmiv/kacy. Easterly winds around 10 knots or less.

Wednesday night and Thursday... Deteriorating conditions as rain
moves into the area.VFR conditions with periods of MVFR/ifr in
showers/thunderstorms. Easterly winds around 10 to 15 knots becoming
south to southeast around 10 knots or less late.

Friday... Improving conditions with a return toVFR expected. Showers
possible early. West winds around 10 to 15 knots.

Saturday... MainlyVFR conditions expected. West to southwest winds.

Marine
Winds and seas are expected to remain below SCA criteria for almost
all of the area waters today and tonight. The one exception is the
delaware coastal waters where seas could build to near 5 feet by
tonight, and wind gusts above 20 kt are expected. At this time
though, do not have enough confidence to issue an sca.

Outlook...

Wednesday... Small craft conditions may occur early in the day along
the southern new jersey and delaware coasts due to hazardous seas.

Thursday and Friday... Seas are expected to build in the prolonged
easterly flow. Small craft advisory will likely be needed. Improving
conditions on the waters through Friday as seas start to subside and
winds diminish.

Saturday... Both winds and waves are expected to stay below sca
criteria.

Hydrology
After rain amounts near 3 inches in some places across south jersey,
levels for many creek and rivers in the coastal plains continue to
rise. At this time, all remain below bankfull and flood stages, but
we continue to monitor this area. Models have trended further
southeast and later with heavy rain today. Thus, though these areas
will likely see additional rain late today, we are expecting
generally light rain amounts (near or below one quarter inch).

A wet pattern looks to continue for much of the week. The next
period of heavy rain could come as early as Wednesday night into
Thursday.

Tides/coastal flooding
Astronomical tides are running higher than normal this time of
year. With the new moon taking place on Thursday, combined with
a possible prolonged easterly flow, we may see some of our
coastal sites exceed minor tidal flooding levels during the
Wednesday and Thursday evening tide cycles. There is also a
small chance that we could reach moderate levels in a few spots.

Phi watches/warnings/advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.

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.
