Synopsis
High pressure will build off shore today. The next cold front is
expected to arrive in our region Saturday. High pressure will then
build in from the west on Sunday and Monday. A second cold front is
forecast to arrive on Tuesday, followed again by high pressure on
Wednesday and Thursday.

Near term until 6 pm this evening
High pressure will move offshore today so a
continuation of fair weather is expected. Skies will be sunny and
after a cold start, temperatures will climb into the upper 50s low
60s in most areas. These readings will be a few degrees below normal
for mid-october. Winds will be light this morning and then SW around
10 mph this afternoon.

Short term 6 pm this evening through 6 am Saturday
Low pressure will be moving across southern canada and
therefore moisture will advect across the area tonight. Increasing
clouds and higher chc for showers will be the result. Pops are in
the high chc low likely range for this period. Total rainfall around
a tenth of an inch will be common for our area. It will milder
tonight with lows in the mid upper 40s N W and low mid 50s S e.

Winds will be mostly SW at 5 to 10 mph.

Long term Saturday through Thursday
Summary... Focus through the long term is on a pair of cold
fronts. The first one should sweep through the region on
Saturday, while the second one is set to arrive on Tuesday.

Details:
Saturday and Saturday night... Cold front should arrive through
during the day. Interestingly, we may not get much precip with
the front (save for southern delaware and far SE nj), but could
see a round of precipitation behind the front due to a
combination of the vorticity maximum ahead of the mid and upper
level trough and lake effect precipitation. If we do have any
precipitation behind the front, it should be mostly rain, though
the higher terrain of the poconos and NW nj could see some
flurries mixed in. Not surprisingly with this scenario, the one
possible limiting factor is how quickly we will see dry air
advection behind the front.

Sunday and Monday... Similar to the pattern we experienced
yesterday into today, we should see a surface high build east
through this time. Consequently, breezy northwesterly winds on
Sunday will slowly subside into Monday as the pressure gradient
decreases.

Tuesday... This period is interesting because the overall
pattern has some characteristics of a clipper system. A very
fast moving trough will dig southeast out of manitoba into the
great lakes region, before lifting northeast. The cold front
associated with this low is currently forecast to propagate all
the way through the region and well to our south before stalling
and dissipating. There is always a bit of uncertainty with how
far south fronts will get with such fast moving systems.

However, given the current pattern and relatively good model
agreement, it is likely this cold front will make it through our
region. Precipitation is possible, but so far unlikely with
this system as we could be in the prime location for the dry
slot ahead of the front.

Wednesday through Friday... Surface high once again builds east
leaving us in a benign, if not colder than normal, weather
pattern. Some of the models depict a warm front arriving late
next week, but that would take a significant pattern change, so
that scenario is very uncertain at this time.

Aviation 07z Friday through Tuesday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Today...VFR conditions expected with light winds this morning. Winds
will begin to increase later this morning reaching 10-12 knots this
afternoon. Wind direction will be W then sw. Few ci cs late.

Tonight...VFR continues with increasing clouds. Sct showers are
expected across the terminals beginning around midnight and lasting
(at least) through dawn. Winds will be mostly SW at 5 to 10
knots.

Outlook...

Saturday... MostlyVFR conditions. However, there is a chance
for rain showers which could result in temporary ceiling and
visibility restrictions. Westerly winds gusting to near 20 kt
through the day, becoming northwesterly late in the day with
gusts as high as 25 kt.

Sunday through Tuesday...VFR conditions expected. Northwesterly
winds gusting up to 25 kt on Sunday. Otherwise, mostly light
(less than 10 kt) winds Monday and Tuesday.

Marine
High pressure moves offshore today while low pressure
strengthens and moves across ontario and quebec. The pressure
gradient strengthens and winds will freshen across the waters later
today and tonight. Scattered showers will arrive late tonight. We
will convert the gale watch to a warning and leave the times
unchanged from before. The SCA for the upper delaware bay will be
left as is. Seas on the ocean will increase to 4 to 6 ft by dawn
Saturday.

Outlook...

Saturday... SCA conditions may linger on the coastal waters for
much of the day.

Saturday night and Sunday... Winds will increase once again.

There is a chance for gale force gusts primarily on the atlantic
coastal waters late Saturday night through Sunday morning.

Monday and Tuesday... Winds are likely to stay below sca
criteria. There is a chance for elevated seas on the coastal
waters on Tuesday, but confidence is low on this.

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.
