Synopsis
High pressure over the midwest will build east and will move
off the mid-atlantic coast later this week. A cold front
gradually approaches early next week.

Near term until 6 pm this evening
High pressure builds across the area today, providing quiet
weather across the region as mostly sunny skies prevail. Winds
will shift from the north this morning, to west through the day
as the center of the high shifts slightly southward. Highs will
be close to or slightly below normal across the area.

Short term 6 pm this evening through 6 am Wednesday
High pressure remains in control of the weather tonight across
the region. Skies remain mostly clear and winds will become
light and variable or calm for most places. This will allow for
temperatures to cool once again to near or slightly below normal
for most places. We maintain the frost advisory for portions of
the pine barrens of southern new jersey as temperatures there
may cool enough for some areas of frost to develop. Portions of
northern new jersey and northeast pennsylvania may stay just
warm enough for only patchy frost to develop in the isolated
coolest spots.

Long term Wednesday through Monday
A prolonged period of dry weather is on tap for long term as
high pressure builds east and remains in control of the weather.

Temperatures will gradually warm up, and will end up being
above normal for the end of the week and into the weekend.

High pressure will be centered south of the DELMARVA peninsula
on Wednesday. Return flow sets up behind the high, allowing high
temperatures to warm up by about 10 degrees compared to
Tuesday, and highs will be in the upper 60s to low 70s.

The high moves offshore on Thursday, and then another area of
high pressure will become entrenched over the mid-atlantic and
southeast u.S. For the weekend. Highs will gradually rise into
the low to mid 70s, and overnight lows will be in the 40s to low
50s.

High pressure moves offshore on Monday. A cold front approaches
late in the day.

Aviation 10z Tuesday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Vfr conditions will prevail today and tonight. Winds will shift

this evening and overnight.

Outlook...

Wednesday through Saturday...VFR.

Marine
We extended the small craft advisory through 11 am this morning
as winds remain around 25 to 30 knots and seas are around 4-6
feet in some areas. As high pressure continues to build across
the area, winds will lighten and seas will subside and the
advisory will be able to be come down later this morning.

Conditions the rest of today and tonight will remain below
advisory levels.

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.
