Update
Little change to the pattern from yesterday. The atlantic surface
ridge axis continues to extend across the northern part of the
peninsula, keeping an east to southeast wind flow in place. Some
scattered showers and a few storms linger mainly across southwest
florida, but these should quiet down in a couple of hours with a
quiet overnight period expected. Wednesday looks to be more of the
same with showers and thunderstorms making their way toward the west
coast through the afternoon and evening hours. The only changes made
to the forecast were for near-term pops to account for radar trends.

Aviation
MainlyVFR conditions are expected. Widely scattered showers and a
few storms continue over southwest florida, so will keep vcts
mentioned for another hour or two. A quiet overnight period is
expected with light and variable winds. Winds then become more
southeasterly in the morning, with another round of showers and
thunderstorms expected in the afternoon and evening hours.

Marine
High pressure will keep southeast winds in place for the next several
days, although the sea breeze will turn winds onshore near the coast
each afternoon. Winds and seas will be briefly higher near
thunderstorms, but no headlines are expected.

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.
