Synopsis
A cold front will move across the middle atlantic region
tonight and then stall to the south. Several waves of low
pressure will move northeast along this roughly stationary
frontal zone, resulting in periods of rain from Thursday through
Sunday. Another cold front will cross the area late on Sunday.

This will be followed by high pressure which should be across
the area through the middle of next week.

Near term until 6 am Thursday morning
Following the warmest february day on record in much of our
region, changes were beginning to take place early this evening.

A cold front extended from new england, across eastern
pennsylvania to the southern appalachians. The front was already
through the poconos at 6:30 pm. The boundary will continue to
progress southeastward and it is expected to reach far southern
new jersey and the middle DELMARVA by midnight.

Showers are expected in the vicinity of the cold front and they
should linger overnight. There will be a noticeable drop in
temperature. Isolated thunder will occur mainly in southeastern
pennsylvania this evening.

Under a cloudy sky, temperatures are forecast to drop into the
30s in the poconos and in far northern new jersey by morning.

There is a small chance of spotty freezing rain in the elevated
terrain of monroe county around daybreak. Readings should fall
into the 40s in the lehigh valley, southeastern pennsylvania,
the remainder of new jersey and the far upper delmarva. Lows are
expected to be around 50 degrees in central and southern
delaware and in the adjacent counties of eastern maryland.

The wind is anticipated to settle into the north and northeast
around 6 to 12 mph after the front passes.

Short term 6 am Thursday morning through 6 pm Thursday
As the deep layer flow becomes parallel to the front, it will
stall nearby, with disturbances riding along it. This will lead
to a more steady light rain during the day across the region.

The highest amounts are forecast for the lehigh valley, where up
to a half an inch of rain is possible. Some sleet could mix in
during the afternoon across the southern poconos - carbon,
monroe, and sussex (nj) counties. Temperatures are expected to
be warm enough to preclude freezing rain. Otherwise, skies will
be overcast, and it will be much cooler. High temperatures will
be in the 40s, with mid- 30s across the southern poconos. A
rather raw east-northeast wind will gust 20-25 mph at times,
making it feel cooler.

Long term Thursday night through Wednesday
A wet pattern is expected for the beginning of the long term
with a stalled front in the vicinity and several waves traveling
along it. The periods with the greatest chances for precip will
be Thursday night into Friday... Mostly N and W areas and
Saturday afternoon through Sunday... All areas. Most areas will
have rain during these periods, but there is the possibility for
freezing rain and perhaps some sleet Thursday night and Friday
morning for the higher elevations of the N W areas. We may to
consider some wsw flags for those periods in upcoming fcsts. We
will be sending out a blast notification to some of the partners
this afternoon. Temperatures will be near normal from Thu night
through Friday night, but above normal Sat and Sunday. Overall,
total precip through this period will range from 1.5 to 2.5
inches across the area. Some of the rivers and streams may show
some effects later this weekend.

Monday thru Wednesday look to be mostly dry ATTM with strong
high pressure building down across the ohio valley then towards
the east coast. Temperatures should average a little above
normal with highs across most areas in the low 50s. Up across
the north, readings will be in the mid upper 40s.

Aviation 00z Thursday through Monday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Outlook...

thu night thru Sunday... Widespread low CIGS and occasional low
vsbys in rains and fog. A little frozen precip confined to the
far N W areas near kmpo Thu night and Friday. Mostly E NE winds
thru the period, but some NW W winds sat. Speeds mostly around
10 knots.

Sun night and Monday... Improving conditions Sunday night with
vfr expected for Monday.

Marine
A cold front moves across the waters tonight, with winds
veering from southwest to east-northeast. Winds and seas will
build again Thursday afternoon across the atlantic waters of de

and continuing through Thu night. Still some uncertainty on
reaching SCA wind criteria on de bay, so that will be revisited
in a later forecast for a possible sca.

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.
