Update
A cold front moving southeast through the florida panhandle
and eastern gulf of mexico is on track to push south into
the florida peninsula overnight, with a robust squall line
positioned ahead of the front, just now entering the
coastal waters early this evening. Scattered to numerous
thunderstorms are developing over the florida peninsula
ahead of this storm, and are continuing to lift north
through the forecast area this evening. Storms were a bit
slower in developing this afternoon than were previously
forecast, and hrrr and other short range models are showing
a the squall line breaking apart as it approaches the coast
overnight. As a result, the rain forecast for the overnight
hours was dialed back slightly from what was previously
advertised.

Otherwise, the forecast looks on track, and no significant
changes were needed for the evening update.

Aviation
Scattered showers and thunderstorms will continue to move
north through the area overnight, causing periods of
MVFR-ifr conditions. Widespread MVFR ceilings will spread
across the area overnight as a cold front passes south into
the area. On Thursday, periods of MVFR ceilings will
continue throughout much of the day under breezy northwest
winds.

Marine
Showers and thunderstorms will continue and winds will
increase overnight as a strong cold front pushes southeast
into the coastal waters. Winds are expected to reach
advisory levels offshore overnight, and cautionary levels
nearshore. Winds will turn to the northwest and then north
behind the front tonight and Thursday, and will hold around
cautionary levels. Winds will gradually subside Friday
through the upcoming weekend as high pressure builds in from
the northwest.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
