Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 750 PM EDT Mon Sep 28 2020

FOR THE EVENING UPDATE. A few showers persist over the interior . with an area of showers and isolated thunderstorms over southwest Florida associated with an outflow boundary pushing west toward the coast. Shower activity will end over the next couple of hours with skies becoming partly cloudy to high broken cloudiness overnight. Southwest boundary layer flow over the eastern Gulf of Mexico ahead of a cold front combined with a fairly saturated conditionally unstable atmosphere will allow scattered showers and possibly a few thunderstorms to develop over the coastal waters after midnight which will begin to advect locally onshore late tonight and into tomorrow morning. The cold front will push across the forecast area late Tuesday and Tuesday night with a potential band of showers/thunderstorms, with a few strong storms possible mainly across the northern nature coast . but could extend as far south as the Tampa Bay area.

TBW WATCHES/WARNINGS/ADVISORIES. FL . None. Gulf waters . None.

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.
