Update
The forecast is right on track. Much colder and drier air has
advected into the region as high pressure builds in from the
northwest. It will be a chilly night for inland locations with
min temperatures around 10 degrees below normal. Not really
expecting frost to be much of an issue considering that winds
will not totally decouple, and dewpoint depressions look to be a
good 3 to 5 degrees at the coldest point near the time of sunrise
tomorrow morning. Nevertheless, there could still be some very
patchy frost at our normally colder and lower lying locations
that are wind protected across far inland southeast georgia and
in the suwannee valley region of northeast florida.

Aviation
Vfr conditions will continue into Monday morning. Return of
onshore flow on Monday will bring some scattered marine clouds
around 3000 feet, especially to the coastal TAF sites.VFR
conditions are expected to prevail.

Marine
Small craft advisory still looks good across the offshore zones.

An expiration time during the early morning hours tonight still
looks to be a good call. Northwest winds this evening will
steadily veer to the northeast by sunrise tomorrow morning. Small
craft will need to exercise caution in all of our adjacent coastal
waters on Monday for northeast winds of 15 to 20 knots.

Rip currents: moderate risk expected on Monday as onshore flow
develops.

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.
