Update
12z sounding this morning showed precipitable water values
remaining near 2 inches. A stalled frontal boundary was located
east west across north central florida, and isolated showers were
near the boundary. A waterspout is possible near this boundary
this morning. Isolated to scattered showers are possible for the
east coast mainly this morning, with scattered showers and storms
possible for the interior and west this afternoon (mainly south of
i-10 and west of highway 301). East to northeast onshore flow
will increase today, with breezy winds 15-20 mph along the coast
this afternoon. Onshore flow and mostly cloudy skies will lead to
temperatures in the low to mid 80s for coastal areas, and mid to
upper 80s inland. The gulf coast sea breeze may not develop, and
models have been trending lower with rain chances this afternoon
due to lower instability from cloud cover. So, cut back pops
across the interior and western portions of northeast florida to
30-50%, with 10-30% across southeast georgia.

Aviation
Ifr lifr CIGS at kgnv will lift this morning.VFR conditions are
then forecast through the period. East northeast winds will
increase to 10-15 knots with gusts of 20-25 knots this afternoon

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.
