Hotter today with a low chance of aftn rainfall mainly across
ne fl...

Update
Surface high pressure extended across the local area from a ridge
centered offshore of the local atlantic coast. This ridge axis
will linger through the day as a weak trough axis edges southward
across northern ga. Aloft, a weak short wave trough was sliding
ese across western ga, with some mid high clouds clusters passing
over the local area. The morning 12z jax sounding showed stronger
mid low level subsidence inversions compared to yesterday,
especially below 700 mb. Very weak low level flow was in place,
with mid upper level flow primarily from the wnw. There is
moisture present below 700 mb, around 1.3 inches pwat, which is
right near daily climo value.

Mostly dry weather today as temps warm into the low 90s inland,
trending a couple degs warmer than yesterday due to subsidence
increasing in the mid levels. Continued with low rain chances
focused across inland NE fl through the afternoon, quickly fading into
the early evening across our suwannee river valley zones. Low
level moisture remained, and expect weak upper level forcing per
the passing short wave trough across NE fl this afternoon and low
level convergence per the sea breezes. Anticipate spotty showers
initiating near the st. Johns river basin by early afternoon,
inland of the east coast sea breeze, then rainfall chances
shifting westward with some increase in intensity and coverage as
moisture is squeezed between the inland progressing sea breezes.

Overall, convective growth will be limited due to dry air above
700 mb (about 10 kft agl), and thus do not expected more than
isolated thunderstorms during peak heating across inland NE fl.

Due to such dry air aloft, showers and thunderstorms will produce
localized gusty winds in downdrafts.

Aviation
PrevailingVFR conditions through tonight, then low chance of
restrictions due to shallow ground fog at mainly crg, jax, vqq and
gnv. Trended toward MVFR at vqq and gnv based on persistence after
06-08z tue. May need to include tempo restrictions due to spotty
showers this afternoon near jax, vqq and gnv, but overall, dry
conditions expected. Breezy ese winds increase at coastal
terminals early afternoon, then progress inland through early
evening as east coast sea breeze edge inland. Gusts near 15-18
kts expected, more persistent along the coast trailing sea breeze.

Marine
Ssw winds with land breeze early this morning will transition to
sse by midday as east coast sea breeze sets up. Winds will near
10-15 kts along the coast and over inland waterways this afternoon
and evening with the sea breeze. Morning rainfall over the outer
waters will fade into the afternoon. Combined seas generally 3 ft
or less. Potential for building swells as tropical system meanders
south of bermuda through midweek, but local headlines not
expected.

Rip currents: moderate risk NE fl coast today. Long period ese
swells near 0.7 ft with periods of 11-13 seconds continue an
elevated rip current risk along the NE fl coast especially around
afternoon low tide as onshore flow increases with sea breeze.

Fire weather
An extended period of hot and dry weather through the weekend. Although
red flag conditions are not expected, there will be an elevated fire
danger with only spotty rainfall expected through mid-week. Temperatures
will warm well into the 90s each day with afternoon humidity ranging
between 30-40%. Winds will be mainly local terrain influenced, with
daily sea breezes, river breezes and lake breezes. Any showers or
isolated thunderstorms will produce erratic winds and wind shifts
that could impact fire sites. Isolated storms will have the potential
to trigger lightning initiated fires, as is the case in the okefenokee
nwr from a storm Sat night.

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.
