Synopsis
The coastal storm which has been impacting the region will continue
to pull away tonight. A cold front will also move through tonight,
with gusty northwest winds continuing through Saturday. High
pressure will bring dry and mild weather on Sunday. A cold front
will move through Monday with showers possible. A large high
pressure center will bring dry but cool weather for the middle part
of next week.

Near term until 6 am Saturday morning
The areal coverage of the showers is decreasing now and the
rain graupel showers are mostly passing offshore. Lingering
activity through 11pm or so will be covered by small chc pops or
slgt chc pops in the fcst. Snow showers will be possible in the
late overnight across the SRN poconos. Gusty W to NW winds will
continue as the deep low well offshore continues to move away.

Only minor adjustments were made to temps winds for the evening
updates.

Short term 6 am Saturday morning through 6 pm Saturday
The low over the canadian maritimes finally lifts away late
Saturday, and high pressure will build in from the west. Dry
conditions on tap, but gusty northwest winds continue, until
finally subsiding late.

Sunny with highs in the 40s to low 50s, except in the 30s in the
southern poconos.

Long term Saturday night through Friday
Summary... A fairly quiet extended forecast across the area, with
the exception of a strong cold frontal passage Monday night. A
shortwave trough will move toward the region, driving a weak
surface low to move across the central u.S. Toward the mid-
atlantic along a cold front. This shortwave will reinforce the
longwave trough to our northeast as it does so, thus ushering in
colder air. High pressure will build across the great lakes
into the region Tuesday. By Thursday, the high will move off the
coast, leading to milder return flow as we close out the
workweek. More rain is possible as we head into Friday as a cold
front approaches from the northwest. There is some indication
that an area of low pressure may develop off the southeast coast
by Friday, however this remains uncertain and will need to
continue to be monitored.

Dailies...

Saturday night and Sunday... Quiet with temperatures
near normal. Lows Saturday in the mid 20s north to the low 30s
across southern delware. Highs recover to seasonable values as
southwesterly flow develops ahead of the next cold front. Most
locations will top out in the mid to upper 50s.

Sunday night and Monday... Precipitation overspreads the region by
early Monday morning. Mild temperatures continue with lows
staying in the 40s for the most part. Highs will range from the
mid 40s across the southern poconos to the low 60s across
southern delaware. Precip looks to stay all rain during the day
Monday, though a changeover to snow may begin by evening across
the southern poconos.

Monday night and Tuesday... Precip continues across the region as
the cold front continues to advance southward. As the freezing
line makes its way southward, rain will transition to a mix of
rain and snow, eventually transitioning to all snow. It is still
a little unclear how far south this will occur, but at this
point, it looks as if temperatures will cool enough before
precip moves out the area for some snow showers to make their
way into the greater philadelphia metro. Any accumulation would
be very light, though it is still too far out to discuss totals
at this point. Precip should move out the area by Tuesday
afternoon as skies begin to clear. However, it will be much
cooler Tuesday with highs only making it into low 40s for much
of the area.

Tuesday night through Friday night... A relatively quiet period
overall. Cold Tuesday night with lows dropping below freezing
across the area, even into the teens across the southern
poconos. Highs gradually moderating Wednesday through Friday, as
high pressure works its way from the great lakes to the western
atlantic; many locations look to make it into the upper 50s to
near 60 by Friday. Uncertainty in the exact timing of rain
Friday and Friday night, as a cold front makes its way toward
the mid-atlantic, while a wave of low pressure rides along the
stalled cold front to our south from earlier in the workweek.

Went with a blended approach for now, including only a slight
chance for showers early Saturday morning.&&

Hydrology
Much of the precipitation is winding down across the area. It
has been more showery this evening with some graupel mixed in.

Many of the gages that were rising earlier today have crested
and are now falling. The exceptions are:
the gage at pemberton on the north branch rancocas is expected
to remain below flood stage, but slowly rise towards actions
stage tomorrow.

The gage at blackwells mills on the millstone river will climb above
action stage late tonight, but is forecast to remain below
flood stage. It will begin falling by Saturday morning.

The gage at pine brook on the passaic river will climb above action
stage shortly and then continue to slowly climb to near flood stage
Saturday night or Sunday morning.

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.
