Update
Freeze frost products have expired this morning as temps will
climb quickly through the 30s 40s, while low level patchy fog
along inland lakes waterways river basins will dissipate by
the 10am time frame. Mostly sunny with high clouds today and max
temps close to climo values in the lower 60s. For tonight... High
clouds will continue to stream in from the west aloft and temps
not as cool and closer to climo values, but still expect some
possible mid to upper 30s across inland SE ga and the suwannee
river valley of north fl, but with more cloud cover not expecting
much in the way of patchy frost. Lows in the 40s are expected
elsewhere.

Fyi... With lows still close to 30 degrees across SE ga this
morning and upcoming stretch of generally above normal temps the
next couple of weeks, will continue the frost freeze program this
winter for SE ga, until a more widespread "significant" freeze
occurs.

Aviation
Vfr through the period with mainly high clouds increasing tonight.

Marine
Light offshore flow will become onshore E SE late tonight into
Thursday. Lingering seas of 4-6 ft offshore today and will keep
the small craft exercise caution (scec) headlines for one more
update cycle this morning.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
