Discussion
Broad troughing remains over the eastern half of the country, with a
west-southwest flow aloft keeping a steady stream of high clouds
over the local area. At the surface, a messy pattern is still over
the region, with a weak trough extending from the northeast toward
the florida east coast and weak high pressure in place ahead of a
frontal boundary to our west. For today, some shortwave energy will
move over north florida as a weak frontal boundary moves through the
state. We should see some shower activity through the day,
especially north and then over the interior. Conditions otherwise
will be fairly seasonable.

Some relatively drier air behind this boundary will move into the
region for tonight through Wednesday and Thursday, resulting in
cooler morning low temperatures and highs each afternoon several
degrees lower as well.

Global models continue to show more shortwave energy moving into the
southeast for the end of the week, with a surface reflection forming
along the northern gulf coast region. This low is forecast to track
northeast through Saturday, with increasing rain chances across the
forecast area. Still seeing some strength differences with this
system, as the ECMWF shows a stronger low than the gfs, but still
plenty of time to try and work out these forecast details. This
boundary is currently forecast to stall south of the area, keeping
rain chances in the forecast for Sunday. A stronger front will then
move through the area on Monday, with a cooler and drier air mass
filtering in behind it.

Aviation
Some patchy fog can be expected this morning, with MVFR vsbys
possible through around daybreak. Also could have some MVFR CIGS for
a few hours before sunrise.VFR is then expected through the rest of
the day. A few showers will be possible today, but these are not
expected to cause significant restrictions. Light northeast winds
this morning will become more northwest this afternoon.

Marine
A weak frontal boundary will move through the area today, but both
winds and seas will remain below headlines with just a slight chance
for rain. An area of low pressure will approach the area for the end
of the week and move by to the north for the first half of the
weekend, with increasing rain chances across the area. Winds will
likely be around 15 knots periodically, but no headlines are expected
until possibly Saturday, with exercise caution-level winds possible
ahead of a front.

Fire weather
No fire weather concerns as relative humidity values will remain
above critical levels. Some patchy fog will be possible for the next
few mornings, but no significant or widespread visibility reduction
is expected.

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.
