Update
Thin line of showers extending along cold front from jax-gnv and
will continue to move SE through NE fl this morning while
decreasing clouds expected across SE ga the rest of the morning. A
few wind gusts to 25 mph with the front and across SE ga behind
the front with the pressure rises and these will continue into the
early afternoon hours. Temps a bit tricky as brief drop in temps
possible right behind the front, then enough clearing and sunshine
expected for the afternoon to allow for a brief warmup close to
pre-frontal temps or a few degrees higher. Overall expect mid-
upper 60s SE ga and near 70 across NE fl. Tonight... Still features
clear skies and much cooler temps falling into the 30s inland and
40s along the coast and st johns river basin. Still very low
chances for some patchy frost over inland SE ga and suwannee river
valley as temps bottom out in the middle 30s with winds falling to
less than 5 mph and any frost will likely be in wind-protected
areas.

Aviation
A blend of MVFR andVFR CIGS with the front impacting all of the
taf sites this morning. Wind gusts to around 20 knots expected
with the front and for a few hours following the frontal passage.

Skies become clear with weakening winds after 18z through tonight.

Marine
Forecast on track with SCA conds offshore and scec conds nearshore
with the cold frontal passage today and NW to N winds continuing
tonight.

Rip currents: low risk today with only small swell activity and
offshore flow. Winds turn more northeast-east on Monday with
increasing threat of rip currents. This trend of increased rip
current concerns will continue through the mid week.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
