Very hot and humid with heat indices of 104-108f this afternoon...

Scattered to numerous storms expected this afternoon evening...

Update
High pressure ridge has weakened slightly and shifted westward
over the fl panhandle with axis still across SE ga NE fl. Overall
subsidence has lead to mostly sunny skies this morning with full
insolation still expected to push highs into the mid upper 90s
inland and lower 90s at the coast. This combined with humidity and
dew points in the lower middle 70s will have peak heat indices in
the 104-108f range by early this afternoon area-wide. Morning jax
sounding still showing deep moisture with precipitable water
amounts (pwats) of 2.1 inches, and hi-res models are fairly
aggressive with storm chances this afternoon along the east coast
sea breeze as it develop along the coast then northeast flow aloft
around the high pressure will slowly push storms inland where
multiple storm mergers outflows come together for scattered to
numerous coverage area-wide, starting with 30-50% along the coast
increasing to 50-70% coverage over inland areas. Isolated strong
to severe storms expected with local wet microburst potential of
40-60mph winds along with storm motion towards the southwest at 10
mph or less still providing for locally heavy rainfall threat as
well. Convection will come together in large complex over inland
northeast florida this evening with numerous coverage and
widespread convective cloudiness, then slowly fade weaken after
sunset and still expected to be ending by midnight. Fair skies and
continued muggy humid overnight with lows in the 70s, some patchy
fog low clouds possible in areas that receive heavy rainfall
today.

With scattered to numerous storms expected inland today tempo ifr
vsbys and MVFR CIGS have been included at gnv vqq jax crg while
vcts will be needed at ssi sgj. Gusty winds to at least 25 knots
will be possible as well. Convection should end at TAF sites by
21z along the coast and 00z-02z over inland TAF sites withVFR
conds expected through the overnight hours.

Southerly flow will continue with ridge axis across the waters.

Speeds generally in the 10-15 knot range with seas 1-3 ft. Local
sea breeze along the coast and a few storms will develop right at
the coast briefly this afternoon before pushing inland. Sea
surface temps still have cooled into the upper 70s at local
beaches due to some upwelling, with st augustine pier (sauf1) down
to 76 degree water temp this morning.

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.
