Update
Little overall change in the forecast for today. Sfc high pressure
was located from ms to nc at 1026 mb and is forecast to slide
eastward through late evening. Cold front that pushed through in the
last 24 hrs is over central fl and will continue pushing swd. Models
also indicate mid level ridging will build across the ERN gulf of
mexico as a mid level disturbance lifts northeast through mexico, tx,
and ok.

Our current cloudiness over NE fl with CIGS around 4-6kft will
slowly drift east-southeast per latest vis imagery and NAM forecasts
of 295 and 300 k isentropic surfaces. Other high clouds will
continue but become more thin today... Only to increase again tonight.

High temps today are tricky over the SRN most zones where the clouds
may linger and keep mostly cloudy skies going through most of the
aftn. Current thinking is to trim highs back slightly in some of
these areas. Otherwise... Still looking at below normal temps today
and remaining dry.

Aviation Vfr CIGS around 4-6 kft over the NE fl terminals but
should slowly dissipate through the day while shifting east-
southeast. Northerly winds near 5-10 kt will veer around to the
northeast today... Becoming light by later this evening. Can't rule
out some lower clouds near sgj later today as winds become onshore.

Marine
Northerly winds near 15 kt will slowly veer through late afternoon
and into tonight... While decreasing to about 10 kt. Seas are a bit
higher than forecast and will increase slightly for rest of today
and evening.

Rip currents: low risk expected today and Sunday with low surf
heights.

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.
