Update
Only isolated shower or storm left over this evening over land
areas as activity pushed inland with the east coast sea breeze
and outflow boundaries. With loss of heating, convection should
end very soon so will be adjusting pops downward for rest of the
evening hours. A stray shower is possible over the coastal waters
but would likely push northward, staying offshore, due to the mean
low level ridge axis centered near to the ga fl state line. Mid
to upper level debris clouds from aftn convection should thin out
slowly overnight and min temps tonight fairly close to average in
the lower to mid 70s and winds light and variable.

Wednesday, isolated to scattered convection expected, mainly during
the aftn hours. Weak, subtle shortwave trough over southeast ga
may focus the best chance of convection there from late morning
through the late afternoon. Slightly less convection should enable
temps to warm slightly above today's values into the lower 90s.

Aviation
PrevailingVFR expected and light east winds rest of tonight.

Brief MVFR vsby possible for vqq around 06z-10z. East to southeast
winds up to near 10 kt on wed. Fairly low chances of t-storms
wed aftn with best chance for gnv with vcts in place for now
after 19z.

Marine
Current forecast looks on track with southerly winds near 5-10 kt
and seas of 1-3 ft. Will add some isolated showers to the
forecast rest of tonight.

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.
