Synopsis
High pressure over the great lakes builds east today, and
eventually moves offshore on Monday. Low pressure over the gulf
coast states tracks to the east, and slowly impacts the mid-
atlantic during the mid-week period. Another area of low
pressure may affect the area at the end of next week.

Near term until 6 pm this evening
Issued a quick update to remove the expired frost freeze
headlines from the text products, and also made some tweaks to
the near term temperatures, dew points and winds.

After this morning's chill, today will be a nice day as
northwesterly midlevel flow and building surface high pressure
allow for dry conditions with temperatures just a little below
seasonal averages. Winds will be less today as the surface
pressure gradient slackens with the approaching high. A 250-mb
jet streak and accompanying vort MAX should provide some lift in
the upper levels to allow for some high clouds. These may limit
temperatures from climbing a degree or two, and generally
reduced highs by this amount today.

Short term 6 pm this evening through 6 am Sunday
Northwest midlevel flow will continue tonight as a surface
ridge remains over the region. Some perturbations in the
midlevel flow will approach the region by morning, but there is
little lift with these perturbations. Other than some increased
mid and upper-level clouds, not expecting much in terms of
sensible weather impacts.

This means that temperatures will once again be the primary
forecast concern. Could see temperatures flirting with freezing
again in portions of the area with the growing season underway,
but tonight's environment will be a little less favorable. For
one thing, if increased cloud cover is present, some radiation
may be re-emitted to the surface (though the height of the
clouds will not hamper nocturnal cooling as much as one may
anticipate). This will be especially true in the southern cwa,
but how far north these clouds persist may prove critical in how
far temperatures fall in more susceptible locations such as the
pine barrens. At this point, way too uncertain marginal to
issue additional frost freeze products. My suspicion is that no
additional products will be necessary.

Long term Sunday through Friday
High pressure over the area Sunday slowly drifts offshore Sunday
night, and remains over the western atlantic ocean waters
through Monday night before drifting offshore on Tuesday. Plenty
of sunshine and mild, though temperatures will generally be a
few degrees below normal during the day. At night, with clear
skies and light winds, radiational cooling conditions will allow
for colder conditions in the mountains and in the pine barrens
of nj.

During this time, low pressure over the gulf coast states will
slowly track to the east, and will be over the southeast u.S by
Tuesday evening. A warm front just southwest of the region lifts
north through the region Tuesday night as the low tracks north
along the coast.

Though there are rain chances during the day Tuesday lifting
from south to north, the best chances will be Tuesday night as
the low lifts to the north. The low then slowly works its way
north through Wednesday, will be south of long island Wednesday
night, and departs on Thursday. Although there may be a period
on Wednesday where locally heavy rain is possible at times, not
expecting a prolonged period of widespread heavy rain with this
system.

Weak high pressure builds through the region late Friday and
Friday night. Another cold front approaches on Saturday.

Temperatures during this time will generally be at or below
normal levels for most of the week, but temperatures trend
warmer towards the end of next week.

Aviation 13z Saturday through Wednesday

Seas should remain near or below 3 feet.

Outlook...

Sunday through Tuesday... Tranquil conditions on the waters with
sub-sca conditions.

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.
