Update
For those who have been enjoying the cooler weather
recently, enjoy today as it will be the last seasonal day
for awhile as the pattern looks become increasingly warmer
and muggier over the coming days. A decaying front across
north central fl early this morning continues to weaken as
it slips down the state... Settling south of the florida

stable, gradually warming airmass through the weekend. Highs
today will range from mid 60s across the nature coast,
where more clouds are present, to upper 70s across sw
florida. No changes needed for the morning update.

Vfr expected to prevail through the period although a thin
area of low stratus remains near srq keeping ifr conditions
in place but this should be short lived. Light northeast east
winds expected area wide.

Marine
A weak front slowly exits the waters today as high pressure
tracks by north of the state through the weekend with
winds veering from northeast to southeast. The high slips

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.
