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
A 980-mb surface low over the gulf of maine this afternoon will
move to nova scotia by Saturday morning. Another upper low and
its associated surface cold front over the eastern great lakes
will move across the region this evening. The two systems will
combine over the canadian maritimes by Saturday morning.

As the cold front passes through, additional showers are
possible. With forecast MAX temps around 50f this afternoon,
resulting afternoon instability per 12z soundings should be
enough to produce a few showers containing small hail, wind
gusts up to 45 mph, and lightning. Exception will be across the
southern poconos, where temperatures are cold enough to support
a mix of snow and rain showers this afternoon.

Scattered rain and snow showers will persist overnight in the
far northern zones with dry conditions elsewhere. Northwest
winds will continue at 20 to 30 mph with gusts up to 40 mph.

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.&&

Aviation 20z Friday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Rest of today...VFR will be prevailing this afternoon, but
scattered showers and isolated thunderstorms are possible late
this afternoon and this evening which could yield occasional
periods of MVFR. Due to very cold air aloft, any heavier
showers, even without thunder, may contain small hail or
graupel. Best chance for this looks to be ilg, miv, and acy, but
have mentioned shower potential at all sites. Wnw winds 15 to
20 kt with gusts up to 35 kt.

Tonight... Any lingering shower activity should dissipate soon
after 0z. GenerallyVFR, although occasional MVFR ceilings
possible at rdg and abe and cannot rule out a passing snow
shower at those sites through midnight. Wnw winds remain
elevated at 15 to 20 kt with gusts up to 35 kt.

Saturday...VFR. NW winds still around 15 to 20 kt with gusts to 35
kt. By mid to late afternoon, winds should start to diminish with
gusts falling below 30 kt.

Outlook...

Saturday night-Sunday night...VFR, except MVFR possible late
Sunday night. Wnw winds Saturday night will become westerly then
southwesterly on Sunday and through Sunday night. Lingering
gusts of 20 to 25 kt possible early Saturday night, otherwise
speeds 5 to 10 kt.

Monday-Monday night... MVFR and possibly ifr Monday with rain
showers. Winds shifting from southwesterly to westerly to
northerly on Monday with speeds 5 to 10 kt.VFR by Monday night
with winds northerly or northeasterly at around 10 kt with gusts
to 20 kt.

Tuesday-Wednesday...VFR. Northeast winds 5 to 10 kt becoming
easterly at 5 to 10 kt on Wednesday. Gusts to 20 kt possible
Tuesday morning.

Marine
A gale warning remains in effect for all waters. Northwest
winds 20-30 kt with gusts up to 45 kt gusts through tonight.

Saturday... Northwesterly gales continue for much of this
period, but wind speeds should gradually drop off late Saturday
into Saturday night.

Outlook...

Sunday through Monday... Sub SCA conditions with northwesterly winds
of 10 to 15 knots. Some higher gusts possible Sunday and Monday
afternoon of 15 to 20 knots. Wave heights of 1 to 3 feet.

Tuesday... SCA conditions possible with northerly winds 20 to 25 knots,
with gusts of 25 to 30 knots possible. Waves of 4-7 feet
possible.

Wednesday through Friday... Sub SCA conditions with northerly
winds of 10 to 15 knots Wednesday turning more southeasterly by
Friday with speeds dropping to 5 to 10 knots. Waves generally 2
to 4 feet.

Hydrology
The heavy rain is coming to an end. In excess of two inches fell
across SE pa and northern nj. As a result, we are looking at a
handful of gages that are expected to approach flood stage.

The rain that fell across chester county is moving down the
brandywine. The gage at wilmington is currently above action stage
and is forecast to crest shortly. No flooding is expected.

The rain that fell across berks and montgomery counties is moving
down the schuylkill. The gage at norristown has climbed above
action stage and is expected to crest just below flood stage this
afternoon.

The gage at pemberton on the north branch rancocas is expected to
move into action stage later today, but remain below flood stage.

The gage at blackwells mills on the millstone river will climb above
action stage tonight, but is forecast to remain below flood stage.

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.
