short term (today-Tuesday)...

mid upper level ridging will remain over the region with surface
high pressure continuing to ridge southwest from the atlantic
ocean across the florida peninsula keeping an easterly flow in
place. Some drier air will move into the region this morning and
hold on into the early afternoon hours delaying the onset of
convection, but deeper moisture will return later in the afternoon
into the evening so more scattered to numerous showers and
thunderstorms are expected. Tonight the convection will move out
into the gulf with partly cloudy to mostly clear skies overnight.

On Tuesday we'll see plenty of moisture across the area leading to
more scattered diurnal showers and thunderstorms. Temperatures
will continue to be near to a few degrees above normal.

Mid term long term (Tuesday night-Sunday)...

ridging will be in place across the area at the surface and aloft
through the weekend with east to southeast flow in place and
afternoon sea breezes turning winds onshore along the coast late
in the afternoons. This will also allow for scattered afternoon
and evening showers and thunderstorms across the area. Lows will
generally be in the lower to mid 70s inland and in the mid 70s to
near 80 along the coast. Highs will generally be in the lower 90s
each day.

Marine...

atlantic high pressure will extend across the florida peninsula
and gulf of mexico through the period. Rather benign conditions
are expected each day with the main hazard being scattered mainly
late afternoon and evening showers and thunderstorms which will be
capable of producing locally gusty winds and rough seas.

Fire weather...

no fire weather hazards are expected for the next several days as
relative humidity values will remain well above critical levels.

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.
