Evening update
An area of drier air from 850mb to 400mb has greatly
suppressed convection today. A few stray thunderstorms
developed across portions of southern and southwestern
florida earlier, but these have since diminished as the
airmass becomes more stable with loss of daytime heating.

For the remainder of the night, mild conditions are forecast
with light winds.

The forecast looks to be in good shape. Decreased pops over
the area the remainder of the evening as showers and storms
continue to dissipate.

Aviation (00z tafs)
Vfr conditions to prevail through much of the TAF period.

Winds to become light and variable overnight, then shift to
the west to southwest from 16z to 20z Wednesday. Spotty
thunderstorms to develop 18z to 21z, mainly affecting inland
terminals and those along the southwest florida coast.

Marine
Light winds and seas will continue as high pressure remains
parked over the waters. A weak front will approach the
northern waters by the weekend, with slightly stronger winds
developing over the weekend. This system may also result in
more widespread marine thunderstorms, which will locally
enhance winds and seas.

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.
