Synopsis
High pressure will slide across to the north of the region
tonight as a nearly stationary boundary remains across just to
our south. Meanwhile, a low pressure system will develop across
the great lakes region and track eastward, dragging a cold front
into our area on Saturday and stalling out across our southern
zones. The boundary will start to lift northward as a warm front
late Saturday into Sunday. Another low pressure system will
cross to the north of our area with its attendant cold front
moving through Sunday night. High pressure will build into the
region through midweek. Another system will approach the region
late Wednesday into Thursday.

Near term until 6 am Friday morning
The area of rain that affected our region today was continuing
to move to our east and southeast this evening. The rain had
ended in eastern pennsylvania, the far upper DELMARVA and much
of new jersey (except CAPE may county) by 7:00 pm. There will be
a lull in the rain for much of the overnight period until
another area of rain begins building into our region from the
southwest toward morning.

The threat of freezing rain has ended in our far northern
counties for the time being. As a result, we have adjusted the
timing on the winter weather advisory to cover the next
potential for freezing rain on Friday morning. It is no longer
in effect for the tonight.

Low clouds will remain over our forecast area during the night.

The wind should be from the northeast and east around 5 to 12
mph, with some gusts near 20 mph on the coastal plain this
evening. Temperatures are anticipated to drop only a few degrees
from the 7:00 pm readings.

Short term 6 am Friday morning through 6 pm Friday
Freezing rain continues for far northern zones for much of
Friday morning, eventually changing to plain rain by Friday
afternoon. Aforementioned winter weather advisory will be in
effect from 7 am until 1 pm Friday.

For the rest of the region, plain rain, though a cold rain, as
highs will generally be in the 40s. With the low taking more of
a northerly path as opposed to the low today, looks as if the
bulk of the precip will fall across pa and much of nj, with
lesser amounts of rain and lower pops for the delmarva.

Long term Friday night through Thursday
Unsettled weather will continue through the weekend before a
quiet period begins for the early through mid week period.

Friday night through Sunday night... An unsettled period for the
region as several systems impact our areas weather.

A low pressure system will develop across the great lakes
region and track eastward towards our area, dragging a cold
front into our area on Saturday and stalling out across our
southern zones. The boundary will start to lift northward as a
warm front late Saturday into Sunday. Another low pressure
system will cross to the north of our area with its attendant
cold front moving through Sunday night.

With all of these systems will come periods of rain, including
some heavier rain over the weekend. With some pretty wet
antecedent conditions and frozen (or at least partially frozen)
ground, we may see some localized flooding occur, especially in
the more prone locations. Guidance is showing between 1-3 inches
through this period with the bulk of the precip falling north
and west of the i- 95 corridor. We will continue to monitor the
flooding threat but right now it looks like the mainstem rivers
will be mostly fine, at least through Sunday. Some residual
draining may cause some rises into Monday and we will monitor
that through the weekend.

Monday through Wednesday... High pressure will build across the
region allowing for the area to dry out and warm up a bit.

Temperatures should rebound from where we are over the weekend
and highs are expected to rise back into the upper 40s to mid
50s across the area.

Wednesday night through Thursday... The high breaks down and
slides to the southeast of the area. Meanwhile, an area of low
pressure will develop across the midwest and track to the east.

This system will push a warm front into DELMARVA on Thursday.

Low pressure may develop along this boundary and then track
towards the coast Thursday night. Lots of uncertainty,
especially with front locations and timing, but another round of
rain is likely across parts of the area. With temps a bit
colder across the northern zones, a few flakes may fall early
Thursday if enough moisture remains across the region.

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

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.
