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 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. |
