Update
An area of low pressure was over southern florida this morning,
with the trough axis extending northeast from south florida to
east of central florida under a mid upper level trough. This area
of low pressure is forecast to drift northward today, and move
off the east coast of south central florida overnight tonight. An
upper trough over the northeast and mid atlantic states was
driving a backdoor cold front southward over the carolinas, and
this boundary will push towards the altamaha river by Sunday
morning.

The 12z sounding this morning showed northeasterly winds above
the surface and northerly winds above 600mb. Dry air was noted in
the mid levels, and the overall flow is not conducive for
significant convection today across northeast florida. Isolated
to scattered showers over the coastal waters may impact the
beaches through the early afternoon with widely scattered
showers storms across interior northeast florida this afternoon.

The highest rain chances (40-70%) will exist over interior
southeast georgia where deeper moisture resides ahead of the
backdoor frontal boundary. Shallow convection will move to the
west to southwest, with deeper convection moving southwest to
south southwest. Highs today will be in the low to mid 90s across
the interior and the upper 80s to near 90 at the beaches.

Aviation
Vfr conditions are forecast to prevail today. An isolated shower
may impact the coastal TAF sites this morning, but chances too low
to mention in the taf. The highest rain chances will exist away
from the TAF sites today across interior southeast georgia. Light
winds this morning will become east to east northeast around 10
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.
