update...

surface high pressure moving offshore the mid atlantic coast
combined with a shortwave trough cold front approaching from
the west will support a breezy southerly wind flow across
the forecast area the remainder of today with warm and
increasingly muggy conditions as dew points climb into the
60s. 12z RAOB data shows a strong subsidence inversion around
850mb with very dry air noted above the inversion which
will keep rain out forecast today with moisture pooling
below the inversion supporting intervals of clouds sun.

Warm air advection will support warmer temperatures across
the region with highs climbing into the upper 70s to even
some lower 80s during the afternoon. With winds in the 30 to
35 knot range off the deck via RAOB data will bump up winds
into the breezy range (15 to 20 mph) in a mid morning
update as mixing should allow some of these stronger winds
to mix down to the surface during the afternoon, otherwise
the rest of the forecast is on track with no other changes
planned at this time.

Marine...

surface high pressure moving offshore the mid atlantic
coast combined with an approaching cold front to the west
will support southeast to south winds around 20 knot with
higher gusts over the offshore waters the remainder of
the day where small craft headlines are posted. Closer
to shore winds will increase into the 15 to 20 knot range
during the late morning and into the afternoon as stronger
winds aloft mix down to the surface. Given this will post
exercise caution headlines for the near shore waters as
well as the tampa bay and charlotte harbor waters in the
late morning update. Other than this the rest of the
forecast is on track with no other changes expected at
this time.

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.
