Synopsis
High pressure centered over the mid-atlantic region will dominate
the weather pattern through the upcoming weekend. The only
interruption will be a weak frontal boundary approaching from the
north Wednesday night into early Thursday. As the high moves off the
coast this weekend, a strong southerly flow will bring much warmer-
than-normal temperatures to the region through Monday. A series of
cold fronts will usher in rain... And colder temperatures... During
the first half of next week.

Near term until 6 am Wednesday morning
High pressure with clear skies will continue over the area tonight.

Another cold night is expected, but the coldest temperatures will be
over the pine barrens of nj with slightly warmer readings over the
wrn areas. Consequently, the frost advisory for tonight will be
across the pine barrens. We have also added ocean county, with the
wrn more rural areas expecting frost and none near the shore. Lows
tonight in the low mid 30s over rural nj and upper 30s to low 40s
elsewhere.

Short term 6 am Wednesday morning through 6 pm Wednesday
High pressure continues across the region. Another sunny day is
expected area-wide. Temperatures will moderate back to a couple
degrees above normal levels with highs in the upper 60s to low 70s.

Winds will be light mostly from the sw.

Long term Wednesday night through Tuesday
The mid-level pattern associated with the long term period begins
with a low-amplitude ridge across the eastern section of the country
Wednesday night. A weak trough moves through early Thursday before
another mid-level ridge sets up shop over the east coast by Friday,
with the amplitude of this ridge increasing through the weekend. A
deep mid-level trough then approaches from the west late Tuesday,
signifying major changes next week.

At the surface, high pressure centered over the central applachians
Wednesday morning will drift south Wednesday night and Thursday as a
weak boundary slides in from the north. No precipitation is expected
with this boundary, so its only noticeable effect may be a
slight shift in wind direction and a slight drop in relative
humidity. Then as the surface high begins to push back north,
the nice weather will continue. With the amplitude of mid-level
ridging increasing into early next week, and a southerly flow at
the surface, temperatures will continue to rise too, maxing out
10 to 15 degrees above normal on Saturday, Sunday, and Monday.

A cold front will begin to cool temperatures down Monday night,
with a stronger cold front on Tuesday bringing with it the
coldest temperatures of the autumn season so far by the middle
of next week.

Aviation 19z Tuesday through Sunday
Vfr conditions are expected at the terminals through Wednesday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
