Synopsis
High pressure over the midwest late this afternoon will move to
the east coast on Tuesday and then offshore on Wednesday. A
series of two cold fronts will approach and cross the region
from the north, the first on Thursday and the second on Friday.

High pressure will build into the northeast from the west
Saturday through Monday.

Near term through Tuesday
125 pm... Shortwave trough currently moving east through
virginia and ahead of this considerable cloud cover persists
over the southern half of the forecast area. We also continue to
see returns on radar but due to significant low level dry air
most of this is not reaching the ground. That said, as the
trough moves through this afternoon this combined with the
diurnal heating may still spark some scattered showers over the
delmarva. This continues to be indicated by the high res models.

Elsewhere it should remain dry though.

The aformentioned trough moves off to the east tonight with
skies becoming mainly clear as high pressure moves back in.

Expect lows by morning generally in the mid 20s to low 30s
except low 20s over the southern poconos.

Short term Tuesday night through 6 pm Tuesday
Surface high pressure will build in right overhead for Tuesday
leading to mainly sunny skies with light winds. Expect highs
generally in the middle to upper 40s except upper 30s to low 40s
over the southern poconos and NW nj.

Long term Tuesday night through Monday
A west to east mid level flow will be in place Tuesday night
through Wednesday with high pressure dominating at the surface.

During this time, near normal temperatures and mostly clear
skies are expected, although Tuesday will be a few degrees below
normal.

Another medium wave trough will dig southward across the region
Thursday through Friday. During this time, two main shortwave
troughs appear to cross the area, with each sending a cold front
across the northeast us and mid-atlantic. The Thursday cold
front shortwave combo will likely yield some showery activity across
the forecast area late Wednesday night and Thursday. There are
signals in some model guidance of a coastal system developing
off the mid-atlantic and new england coasts late Thursday into
Friday. Will keep an eye on future guidance but greatest impact
to the area likely to be just higher winds. A secondary cold
front will cross the area again late Friday which will bring
drier and somewhat colder air, but temps will still be generally
near or perhaps a few degrees below normal.

High pressure will return Saturday and persist through Monday.

As the high slides offshore, mean flow will shift southerly and
bring above average temperatures to the region Sunday and Monday.

This combined with mostly clear skies should yield another very
nice weekend for much of the east coast.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
