Update
A few showers and isolated thunderstorms did develop along the sea
breeze and over the interior this afternoon and some of this will
continue over our interior counties for a few more hours. Skies
will be mostly clear overnight with winds becoming light. For
Tuesday more dry air, precipitable water less than 1.5 inches,
will spread southward during the day virtually eliminating and
not allowing convection to develop and only expecting some
scattered cumulus clouds during the day. It will remain hot thanks
to the abundant sunshine with daytime highs climbing into the mid
90s away from the coast. Near the coast the sea breeze will keep
temperatures in the mid to upper 80s. Overall the current
forecast looks good with no evening update needed.

Aviation
Vfr conditions are expected through the forecast period. Winds
will become light and variable overnight and then northwest and
increase to between 8 and 12 knots with some higher gusts during
the late morning and afternoon hours on Tuesday.

Marine
North to northwest winds will be in place for the next couple of
days with no headlines expected. A backdoor cold front will move
through the region on Wednesday, with increasing northeast winds
for Wednesday night into the weekend. Wind speeds are expected to
reach exercise caution criteria, possibly advisory levels, during
the second half of the week.

discussion...

broad high pressure remains anchored aloft over the plains region,
extending over the southeast. At the surface, hurricane humberto
continues to spin off the georgia carolinas coast, with high
pressure over the southeast. Low-level flow is out of the north to
northwest as humberto moves away from the region. Very little shower
activity out there today with some drier air being pulled southward
and similar conditions are expected through Tuesday.

On Wednesday, a backdoor cold front will move through the area, with
a few showers possible ahead of it. For Thursday through the end of
the week and into the weekend, a relatively cooler and drier air
mass will move over the region, with dew points "falling" into the
60s and temperatures dropping a few degrees as well. Although it
isn't much, it will definitely feel more comfortable outside. Rain
chances remain low but then increase for Friday and the weekend as
moisture starts to return over south florida.

Fire weather...

some relatively drier air will work its way into the region over the
next several days, although relative humidity values are expected to
remain above critical levels. Rain chances remain fairly low through
the week except for Wednesday, when a backdoor cold front will bring
a few showers to the region. No significant fog 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.
