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
Rain continues across much of the northern half of the forecast
area as low pressure along a stationary boundary across the mid-
atlantic passes south of the region. A 1042 mb high builds into new
england as a 1033 mb high sits off the southeast u.S. Coast. With
caa funneling into northern zones, expecting a period of freezing
rain this evening for the poconos and northwest nj as surface temps
drop to freezing. Rain moves offshore this evening, and conditions
dry out for most of tonight. Patchy fog will develop tonight with
abundant low level moisture in place.

Another area of low pressure over the tennessee valley will develop
tonight and lift north towards the region late tonight. Precip will
develop out ahead of that low and lift into the region in the pre-
dawn hours of Friday. Expecting freezing rain for the poconos and
northwest nj once again. As a result, will keep the winter weather
advisory in effect, but will also extend it through Friday.

Lows tonight will range from the mid and upper 20s in far northern
zones to otherwise in the mid 30s for most of southeast pa and nj.

Extreme southern nj and the DELMARVA will be in the upper 30s.

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 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.

The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,

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.
