area forecast discussion

628 am edt Tue oct 15 2019

Synopsis
High pressure will be across the middle atlantic today and then
move offshore tonight. Low pressure will move across the great
lakes region Wednesday while a second low forms near virginia.

Both of these low will consolidate into a significant storm east
of the area Wednesday night. The storm will move away Thursday
as high pressure begins to build over the area. The high will
settle over the region this weekend. Another storm will arrive
for the beginning of next week.

Near term until 6 pm this evening
High pressure located in central pennsylvania early this
morning will build eastward. The center of the air mass is
forecast to pass off the new jersey coast early this afternoon.

We are anticipating a mostly sunny sky for today with just a
few cumulus and cirrus overhead. A light northerly wind is
expected for this morning. The wind should become southerly
during the afternoon in the return flow on the back side of the
high.

Maximum temperatures are forecast to be mostly in the middle
and upper 60s in our region. Highs will likely favor the upper
50s and lower 60s in the elevated terrain of the poconos and far
northern new jersey.

Short term 6 pm this evening through 6 am Wednesday
The high should be centered off nantucket early this evening
before moving farther out to sea overnight.

We are expecting an increase in cloud cover in the southeast to
south flow. However, any rain should hold off until after
daybreak on Wednesday.

Low temperatures are forecast to be mostly in the upper 40s and
lower 50s in southeastern pennsylvania, central and southern
new jersey, delaware and northeastern maryland. Lows should
favor the lower and middle 40s from the poconos and the lehigh
valley into northwestern new jersey.

Long term Wednesday through Monday
Wed thu... The weather will quickly deteriorate Wednesday as
strong low pressure moves across the great lakes and its
associated front arrives from the west. A second low will form
on the front near virginia and then 'bomb' as it moves up along
our coastal waters and into new england. A soaking rain and
gusty winds will be over the area Wednesday afternoon an thru
much of the night. A one to two inch rain will occur over most
areas with locally higher totals if convection develops (low
probability). Rains will end from SW to NE overnight as gusty w
to NW develop. Gusts to 40 mph are possible. The gusty winds
will last into Thu before diminishing Thu night.

The models are mostly in agreement with the synoptic factors
with the system, but the exact details of how much rain and
where are yet to be resolved. The rains will be heavy at times
where they setup, but the overall length of precip will not be
much more than 12 hours. This will keep totals from getting too
excessive. Recent dry weather will allow for more absorption by
the soil, provided it doesn't rain at too great a rate. We put
the mention of heavy rains in the hwo for now.

Fri Sat sun... High pressure builds over the area and crests
over the middle atlantic sat. A dry weather regime will
accompany the high with mostly sunny days and mostly clear
nights. Temperatures will be a little below normal fri, near
normal Sat and above normal Sunday.

Mon... Another system will approach from the great lakes Monday.

Increasing clouds Sun night and Mon with chances for rain
increasing Mon and lasting into Mon night. Temperatures Mon will
be above normal with highs reaching the mid upper 60s (n w) and
low 70s over SRN nj, metro philadelphia and delmarva.

Aviation 12z Tuesday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today...VFR under a mostly clear sky. North wind 6 knots or
less, becoming south to southwest in the afternoon.

southeast wind 6 knots or less.

Marine
High pressure is forecast to build across the coastal waters of
new jersey and delaware for today and tonight. A north wind
around 10 to 15 knots this morning should become northeast to
east 5 to 10 knots this afternoon. A southeast wind 10 to 15
knots is expected for tonight.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
