Synopsis
High pressure located in the ohio river valley this evening
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 until 6 am this morning
Surface high pressure builds in from the west. With clear skies
and light winds, excellent radiational cooling conditions
setting up. Lows tonight generally in the teens and 20s, and
around 30 in around philly.

Short term 6 am this morning through 6 pm Wednesday
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 Wednesday 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.

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.
