Synopsis
A large low pressure system will slowly slide east through the
weekend and will weaken as it does so. High pressure will build in
south of the region Tuesday. A cold front may slowly progress
through the region starting Wednesday.

Near term until 6 pm this evening
We'll keep the flash flood watch for now as the axis of
steady showers will be across the area into the afternoon before
moving offshore. Additional heavy showers are still possible with
the possibility for an inch or more thru the morning in some areas.

The chc for a TSTM is still there, especially near the shore, but
the threat for severe tstms is close to zero. Slow improvement in
conditions from W to E today with skies becoming partly sunny in the
w by late morning and then spreading east into the afternoon. It
will remain mild and humid, but not as warm as Friday. Highs will
mostly be in the low 70s.

Short term 6 pm this evening through 6 am Sunday
It will remain unsettled tonight with the upper low
circulating across the area and a slowly drying lower atmosphere in
place. Skies will be partly to mostly cloudy and there will be still
a slight chc for a shower or two. It will remain mild however with
lows mostly in the 50s. A little patchy fog is also possible in
rural areas, especially if the clouds break up more than presently
expected.

Long term Sunday through Friday
Due to the current weather, the long term was not updated on
this shift. It will be updated later today. The extended starts
off unsettled as an upper level cut off low spins across the
eastern us and eventually tracks to the northeast and into new
england late Monday. Meanwhile, at the surface, low pressure
will slowly move through the mid- atlantic and cross our area
Sunday night into Monday. High pressure will nudge its way into
the area late Monday before sliding to our south on Tuesday.

Another surface low pressure system will approach the region
around midweek. Beyond midweek, the guidance diverges and shows
varying solutions from high pressure over the region to having a
slow moving boundary as we head into the end of the week.

Overall, the period looks showery with the exception of
Tuesday, and possibly some areas on Monday. With so much
uncertainty after midweek, confidence is too low to state that
any day will dry. Not much in the way of cold air moving into
the region, although Monday will likely be cooler than most days
of the extended. Depending on how the models resolve the end of
the week, there is still the potential for some cooler air to
arrive. The cooler days look to be close to the climatological
normals for april with the rest of the period remaining above
normal.

Aviation 07z Saturday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today... Showery conditions continue at the terminals early this
morning with widely varying CIGS vsbys.VFR at the delaware valley
terminals and also at krdg. MVFR for kttn kilg with some ifr closer
to the shore. Conditions will likely lower into the dawn hours with
the large batch of showers across the area expected to continue.

Improvement later this morning and into the afternoon from NW to se
as the weather system begins to move away. Winds will be mostly srly
at 10 to 15 knots with g20 knots at times.

Tonight...VFR expected with partly cloudy conditions. Mostly light
s SE winds. Patchy fog is possible, but limited confid in occurrence
attm.

Outlook...

Sunday...VFR conditions with MVFR or lower in showers. Ceilings
may lower through the day. South to southwest winds around 5 to
10 knots.

Sunday night... MVFR or lower conditions possible with showers.

Light southwest to west winds.

Monday... MainlyVFR conditions expected. Showers are possible
through the day, which may cause conditions to become MVFR or
lower for a period of time. West to northwest winds around 5 to
10 knots becoming light and variable overnight.

Tuesday... MainlyVFR conditions expected. Showers arrive from
northwest to southeast, mainly in the afternoon or later. West
to southwest winds around 5 to 10 knots.

Wednesday...VFR conditions becoming MVFR or lower in showers.

West to northwest winds around 5 to 10 knots.

Marine
Winds and seas should remain in the SCA range today and into tonight
for the ocean waters. The present flags will remain in place.

Showers this morning will taper off by late afternoon. Small chc for
some thunder early this morning. Fair weather tonight.

Outlook...

Sunday through Monday... Small craft advisory conditions will
continue on the ocean waters as seas remain elevated. Seas will
start to subside late Monday. Southerly winds on Sunday will
turn to the west then northwest on Monday. Gusts are expected to
remain below 25 knots. Sub-advisory conditions are expected on
the delaware bay.

Tuesday... Southwest winds around 10 to 15 knots with gusts
around 20 knots. Seas 2 to 4 feet.

Wednesday... Northwest winds around 10 knots. Seas 2 to 4 feet.

Hydrology
As mentioned above, the flash flood watch continues across the
region. Rainfall amounts so far have been up to one inch, but
there is a chance another round of heavy rain could develop and
move into the region later this morning.

Tides coastal flooding
The last high tide of significant concern is winding down, except on
the tidal delaware river, where coastal flooding is occuring as of 3
am with the high tide.

Concern remains for some minor flooding on the eastern shores of
chesapeake bay as well for this morning's high tide. We will
continue to monitor. However, latest trends indicate the high tide
should fall just short of advisory levels.

Finally, have seen some minor flooding on the northern shores of
barnegat bay and associated back bays today. With prevailing
southerly flow continuing, expecting more of this through today. I
have extended the current coastal flood statement through the next
high tide later this morning.

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.
