Synopsis
High pressure will slide southward tonight and then offshore through
the weekend. A cold front will approach from the west on Monday,
crossing the area Monday night. High pressure will return for the
midweek period.

Near term until 6 am Saturday morning
Temperatures dropping off fairly quickly due to radiational
cooling from clear skies and light winds. Some patchy fog is
possible in the predawn hours, mainly away from the urban
corridor.

Short term 6 am Saturday morning through Sunday
Dry weather will continue through Saturday and Saturday night
as high pressure remains to our south and a surface trough
remains across the area. Temperatures will warm well above
normal starting Saturday as ridging aloft builds across the east
coast and return flow brings in warmer, more moist air.

Vertical moisture remains limited, so precipitation is not
expected through Saturday night, regardless of any short
wave vorticity impulses.

By Sunday, the ridge aloft breaks down while the high pushes
offshore of the mid-atlantic coast and the weak surface trough
remains near the area. This will allow for the return flow to
continue through Sunday. Very warm temperatures and increasing
moisture are expected through Sunday. Later Sunday, there is a
chance some showers may develop to our west, but they are
expected to stay out of our area and remain near the surface
trough as it drifts westward through the day.

Long term Sunday night through Friday
Not much change in the extended period as we are largely dominated
by high pressure. Main opportunity for precipitation will be with
the frontal passage on Monday night.

A cold front will approach the region from the west on Monday,
crossing through the area Monday night. Low level moisture will be
on the rise in the return flow around the departing high pressure.

Flow looks to be pretty progressive with the front working through
the area Monday night and then offshore by Tuesday morning. Some
instability may develop head of the front with the best forcing
right in front of and along the boundary. Only will mention a slight
chance of thunder, mainly during the afternoon, with it waning once
we head into the evening and lose the diurnal component.

Once the front moves through, high pressure starts to build back
into the region. There may be a weak front that moves through on
Thursday but most guidance shows little moisture around and it may
not be much more than a wind shift across our area.

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.
