Update
Smoke in baker county will impact the i-10 area overnight as smoke
from the fire settles closer to the surface due to reduced winds
and an elevated inversion. We will be monitoring areas for
potential dense smoke settlement overnight. Dry conditions and
clear skies will persist overnight with low temperatures ranging
between the mid 50s to low 60s. A weak cold front is still
expected to move across the forecast region Thursday evening
bringing scattered showers and isolated storms across SE georgia,
mainly NW of waycross.

Aviation
Vfr conditions will continue throughout the night with reduced
winds out of the southwest. Slight chance of patchy fog near
gainesville is possible prior to sunrise. Windspeeds will increase
to 10-15 knots in the early afternoon.

Marine
West to southwest offshore flow will continue the next few days
with wind speeds and sea heights expected to be mostly below
headline criteria. The exception will be Thursday night when scec
conditions will be possible offshore due approaching front.

Frontal passage may be slow on Friday but likely moving south of
the area late Friday night per NAM and gfs. Fairly weak pressure
gradient on Saturday but another surge of cooler air may arrive
on Sunday with potential slightly higher northerly winds.

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.
