Daytime heating combined with conditionally unstable atmosphere will cause scattered showers and thunderstorms to develop over the coastal counties during the morning and early afternoon hours... Which will push inland and increase in areal coverage through the remainder of the day. Scattered evening thunderstorms mainly over the interior will dissipate by midnight with skies becoming partly cloudy after midnight. Long term (Tuesday night-Sunday) Boundary layer flow will veer northwest on Wednesday. Slightly drier air over the region will decrease pops a bit with best chance of showers and thunderstorms over the interior during the mid late afternoon. Weak boundary layer flow on Thursday will allow west and east coast sea breezes to collide over the interior peninsula where highest pops will occur. Surface ridge will build north of the region Friday and over the weekend with boundary layer flow shifting to the east. This will hold the west coast sea breeze boundary over the coastal counties... With the east coast sea breeze colliding with the west coast sea breeze along the west coast of florida late in the day with showers and thunderstorms likely. |

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. |
