Synopsis
High pressure will slide southward tonight and then offshore through
the weekend. A cold front will approach from the west on Monday,
crossing the area Monday night. High pressure will return for the
midweek period.

Near term until 6 am Saturday morning
Another quiet night ahead tonight as high pressure remains to our
south an a surface trough remains in place. Even with a couple of
weak short wave vorticity impulses overnight, only periodic cloud
cover is expected as there is limited moisture. As winds go light
and temperatures cool, some patchy fog is again possible.

Short term 6 am Saturday morning through Sunday
Dry weather will continue through Saturday and Saturday night as
high pressure remains to our south and a surface trough remains
across the area. Temperatures will warm well above normal starting
Saturday as ridging aloft builds across the east coast and return
flow brings in warmer, more moist air. Vertical moisture remains
limited, so precipitation is not expected through Saturday night,
regardless of any short wave vorticity impulses.

By Sunday, the ridge aloft breaks down while the high pushes
offshore of the mid-atlantic coast and the weak surface trough
remains near the area. This will allow for the return flow to
continue through Sunday. Very warm temperatures and increasing
moisture are expected through Sunday. Later Sunday, there is a
chance some showers may develop to our west, but they are expected
to stay out of our area and remain near the surface trough as it
drifts westward through the day.

Long term Sunday night through Friday
Not much change in the extended period as we are largely dominated
by high pressure. Main opportunity for precipitation will be with
the frontal passage on Monday night.

A cold front will approach the region from the west on Monday,
crossing through the area Monday night. Low level moisture will be
on the rise in the return flow around the departing high pressure.

Flow looks to be pretty progressive with the front working through
the area Monday night and then offshore by Tuesday morning. Some
instability may develop head of the front with the best forcing
right in front of and along the boundary. Only will mention a slight
chance of thunder, mainly during the afternoon, with it waning once
we head into the evening and lose the diurnal component.

Once the front moves through, high pressure starts to build back
into the region. There may be a weak front that moves through on
Thursday but most guidance shows little moisture around and it may
not be much more than a wind shift across our area.

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

a few locations, mainly rdg, miv, and acy. Southwest winds 5-10
knots or less early this evening, then light and variable overnight.

Saturday...VFR conditions expected. Light and variable winds early,
increasing out of the southwest 5-10 knots during the day.

Outlook...

Saturday night... MostlyVFR conditions expected. Patchy fog may
develop for a few locations, mainly rdg, miv, and acy. Southwest
winds 5-10 knots or less early this evening, then light and variable
overnight.

Sunday...VFR conditions expected. Light and variable winds early,
increasing out of the southwest 5-10 knots during the day, with
gusts 15-20 knots possible.

Monday... MainlyVFR expected. MVFR or lower possible in scattered
showers. Southwest winds around 5 to 10 knots with some gusts around
15 to 20 knots (more likely closer to kacy). Winds will turn to the
west and then northwest late behind a cold frontal passage.

Tuesday... MainlyVFR expected. Northwest winds around 5 to 10 knots.

Wednesday... MainlyVFR expected. Light westerly winds.

Marine
Tonight... Small craft advisory continues on the atlantic ocean
coastal waters through tonight with seas around 5-6 feet.

Saturday... The small craft advisory will continue into the first
half of the day, before dropping during the afternoon as seas
subside.

Outlook...

Saturday night... Conditions expected to remain below advisory levels
overnight.

Sunday... Winds increase through the day Sunday and may reach
advisory levels by late afternoon.

Sunday night through Monday night... Seas may start to build to
around 5 feet Sunday night, continuing through Monday night. A small
craft advisory will likely be needed for the ocean waters.

Tuesday through Wednesday... Seas subside into Tuesday morning,
falling below advisory levels and remaining sub-advisory through
Wednesday.

Rip currents...

a high risk for the development of dangerous rip
currents continues through today as the long period swells and high
seas continue from hurricane humberto. A rip current statement
(under the coastal hazard message) is carrying the related info.

The risk for Saturday will be at least moderate, but may possibly be
high like Friday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
