update...

early evening water vapor satellite imagery is showing a
very dry airmass in place aloft of florida, which allowed
mostly clear skies to take over today. Surface ridging will
continue to build in from the gulf tonight and Friday,
keeping skies generally clear through the rest of the week,
supporting cool mornings and mild and sunny afternoons.

The forecast looks on track, with no significant changes
needed for the evening update.

Aviation...

vfr conditions are forecast to hold through the next 24
hours.

Marine...

high pressure over the western gulf of mexico is ridging
east across the florida peninsula and will gradually shift
northeast through the upcoming weekend. A tight pressure
gradient between this ridge and an area of low pressure
along the mid-atlantic coast will produce exercise caution
level northwest winds overnight, then wind speeds will
subside Friday morning through the weekend. Winds will shift
to northeasterly on Saturday and easterly on Sunday, with
afternoon sea breezes near the coast.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
