Update
An inverted coastal trough just offshore volusia county is
maintaining north winds and considerable low clouds across the
northern half of the forecast area. Short term guidance indicates
the trough will push inland later tonight as it becomes overwhelmed
by the strengthening synoptic onshore flow. Adjusted temperature,
sky cover, and wind grids in the near term from ktix-kism
northward to account for the persistence of the trough and its
associated cooler and cloudy maritime flow.

With the surface ridge to our north building closer to the area,
expect onshore flow to increase overnight, drawing slightly higher
moisture off the atlantic. Thus far, mesoscale guidance has
overplayed precip coverage, so opted to reduce pops across the
board. Still, isolated showers over the atlantic will push onshore
overnight, with better inland progression expected north of the
cape where the onshore flow is expected to be stronger with time.

Warmest overnight temps will be along the space and treasure
coasts with low to mid 70s expected, mid to upper 60s expected
elsewhere.

Aviation
An inverted coastal trough near the volusia county coast will
maintain low MVFR (fl010-fl015) ceilings north of a line
connecting ktix-kism through the night. Increasing onshore (east)
flow will cause the trough to push inland and lead to a decrease
in cloud cover Saturday morning; however, moisture off of the
atlantic will still support scattered to occasionally broken
ceilings between fl025-fl035 Saturday afternoon. Gusty onshore
winds expected along the coast overnight from kmlb north and all
aerodromes beginning late Saturday morning.

Marine
Current... An inverted trough north of CAPE canaveral is
maintaining gusty north winds near the volusia county coast, while
lighter southeast winds prevail south of the cape.

Tonight... Steadily deteriorating conditions are expected to spread
from north to south over the coastal waters overnight as high
pressure builds closer to the area and leads to gradually
strengthening onshore flow. Winds up to 20 knots nearshore and
20-25 knots offshore will allow seas to build up to 5-7 feet nearshore
and 8-9 feet offshore. Small craft advisory now in effect north of
sebastian inlet. Will hoist an advisory for the treasure coast
waters beginning Saturday morning at 8:00 am.

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.
