Discussion
Mean layer upper air analyses indicate ridging prevails from the
lower to upper troposphere. The surface high axis lies west across
the florida peninsula. Daytime heating across south florida
continues to perturb the afternoon and evening surface gradient,
much the same as yesterday. As opposed to winds which should be
generally northeast to east, winds are northeast at pulaski shoal,
and southeasterly along the reef southeast of the upper keys. This
localized effect should erode over the next couple hours. As the
high reconsolidates overnight, gentle east to southeast breezes
should develop across the florida keys. Winds will have a hard
time decoupling overnight, so think lows will bottom out near 70.

Rain chances are nearly nil. No changes needed for the current
forecast.

Marine
Broad high pressure will remain north of the coastal waters of
the florida keys overnight through Thursday. A weak frontal system
will approach the keys Thursday night, but wash out to the north
of the keys on Friday. A weak pressure pattern will remain in
place Friday night through Sunday.

Aviation
Vfr will prevail at the eyw and mth terminals. Gentle east to
southeast breezes will develop at both terminals overnight.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
