Synopsis..High pressure will continue to build into the florida peninsula through the afternoon and evening. High pressure will remain over the region through early next week, with light south to southeast winds shifting onshore near the coast each afternoon due to the seabreeze. During this timeframe, the only marine concern will be locally gusty winds and rough seas due to scattered marine Thunderstorms during the late afternoon and evening hours.

Scattered storms and heat indices near 105 degrees this
afternoon...

Update
Transition day as high pressure ridge from the WRN atlc extends
across the forecast area aloft and this will tend to suppress
convection somewhat but morning soundings and satellite derived
products still supporting widespread precipitable water amounts
close to 2 inches that will still allow for at least scattered to
possibly numerous showers storms to develop on the sea breeze
fronts as they move slowly inland. Steering flow from the south
will push stronger storms generally from the south to north at
10-15 mph while still warm mid-level temps at -4 to -6c around
500mb will not support much in the way of severe storms still
expect strong storms with gusty winds frequent lightning and
storm movement and high moisture content supports locally heavy
rainfall. Best storm coverage will be just inland from the i-95
corridor westward to the i-75 corridor as sea breezes meet.

Diurnal heating expected to push inland MAX temps into the lower
90s inland and upper 80s at the coast and this combined with
lingering tropical moisture at the surface will create peak heat
indices around 105 degrees this afternoon. Tonight will feature
storms fading after sunset with all activity ending by midnight
and skies becoming mostly clear partly cloudy with muggy
conditions still continuing with lows generally in the lower to
mid 70s inland and upper 70s at the coast. On Friday as drier
airmass aloft over south fl pushes northward into north fl expect
only isolated storm activity possible across NE fl and widely
scattered across inland SE ga with hot temps into the 90s and high
heat indices close to 105 degrees once again.

Aviation
Ifr MVFR CIGS have popped up at kgnv and for now expect rest of
taf sites to maintain sct decks in the 2000-3000 ft range this
morning but a brief MVFR cig will be possible. Otherwise scattered
convection expected this afternoon argues to keep vcts or vcsh at
all TAF sites as the sea breezes develop and push inland. Activity
still expected to fade during the 00z-02z time frame withVFR
conditions tonight.

Marine
Southerly flow around 15 knots with seas 3-5 ft through tonight.

A slight increase is possible Friday into Saturday to 15-20 knots
and scec headlines may be required briefly at times.

Rip currents: moderate risk in the sideshore southerly flow and
afternoon SE sea breezes. Breakers in the 2-3 ft range.

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.
