Synopsis
High pressure will build in from the northwest and west to close out
the work week, before moving offshore on Saturday. Strong low
pressure lifts northeast across the great lakes over the weekend and
its associated fronts will affect our area. More high pressure will
build in for the beginning of next week. The next low pressure
system may approach from the west and affect the area by next
Wednesday.

Near term until 6 pm this evening
No major changes to the forecast with the mid morning update.

Expecting a blissfully quiet day (at least weather-wise) as
surface high pressure migrates eastward toward the area with
near-zonal flow prevailing aloft on the northern edge of the
subtropical atlantic ridge. Little cloud cover is expected for
most of the area outside of a fairly abundant cirrus deck and
maybe some scattered cold-advection cumulus. High temperatures
will remain near normal with highs generally in the mid to upper
40s (30s in the poconos).

The rain showers have moved south of the region. Therefore, have
lowered pops across DELMARVA through the remainder of the day.

Short term 6 pm this evening through 6 pm Saturday
Friday night will be quiet weather-wise with the surface high
centered just to our north. Light winds with only cirrus will allow
for lows to get below freezing in most locations outside of far
southern nj southern DELMARVA where temperatures may be a bit warmer
due to thicker mid-lvl cloud cover (although this cloud cover could
remain just south of the area).

Long term Saturday night through Thursday
Saturday through Monday...

the main story for this period continues to be strong area of
low pressure that will affect the area late Saturday through
Sunday.

To start the period early Saturday, aformentioned low will be
developing near the texas panhandle while strong high pressure
remains centered over the northeast conus. This high will move
offshore through the day while the low moves northeast toward
missouri. Expect clouds to increase with rain beginning to move
in from SW to ne... Most likely beginning in the mid to late
afternoon and reaching the philadelphia area by evening. The
airmass ahead of this system won't be very cold with highs
Saturday mostly in the 40s so expect precip to be all rain just
about everywhere. However the one area of concern will be across
the far north from the southern poconos into sussex co. Nj. As
precip moves into this area early Saturday evening temperatures
may fall to near freezing for a time so there could be a period
of freezing rain in spots... Especially the higher elevations.

However as the deepening low takes a track well to our north and
west into the upper great lakes it will push a warm front
through changing precip to all rain by the overnight so don't
expect this to be a major or widespread icing event. Otherwise,
the rain may fall moderate to even heavy at times as the system
will be drawing on lots of moisture from the south. In fact
pwats look to reach upwards of 1.5 inches by later Saturday
night. A couple limiting factors though for excessive rainfall
will be that the main upper level forcing will be well to our
north west with this system and the elevated instability looks
to stay just to our south. That said, hydro will have to be
monitored as there will be rises on rivers and streams with a
few of the more sensitive points along the rancocas creek and in
the raritan and passaic basins potentially getting into action
stage or minor flood stage by late in the weekend into early
next week.

The heaviest steadiest rain should be tapering off by around
midday Sunday as the deep low moves into northern ontario and
the system's triple point moves through. Total rain amounts by
this time look to generally be .75 up to 1.5 inches with the
delmarva into southern nj most favored to get the highest
amounts. Beyond this time concern will be strong winds Sunday
afternoon and beyond as a deep mixed layer develops with with
winds in the boundary layer progged to reach 40-50 knots. We
increased the wind gusts with this update as I expect by late
afternoon gusts of 40 to 50 mph will be quite possible.

Temperatures will be quite mild though with highs generally in
the 50s to low 60s.

The winds may abate somewhat for a time Sunday night however by
late night expect another cold front to move through with the
pressure gradient tightening up even more as the low moves into
the canadian maritimes while the next high moves south into the
central conus. It is at this time I expect the best potential
for very strong, potentially damaging W NW winds to occur with
gusts possibly in the 50 to 60 mph range. This would be
beginning near dawn Monday lasting at least through midday. Will
continue to highlight this potential in the hwo. Temperatures
return to near average for Monday with dry conditions and highs
ranging from the 30s across the southern poconos to the 40s
elsewhere.

Monday night through Thursday...

winds abate Monday night with broad high pressure moving in for
Tuesday bringing fair, seasonable weather. Forecast uncertainty
increases beyond this time as the GFS and the gem bring the
next system (a weaker one) in by next Wednesday while the ecmwf
maintains high pressure over the area. For this reason we just
keep low pops in the forecast for the Wednesday Thursday time
frame of next week.

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.
