837 pm edt Sat aug 24 2019

Muggy tonight with increasing coastal showers Sun morning...

Update
Strongest evening convection was focused west of the local area under
light NE steering flow with lingering stratiform fading across our
western zones. Spotty showers possible over the adjacent waters through
the night under weak convergent bands forming under onshore flow as
broad surface low across south fl begins to move east then track
ne through Sunday. Surface high pressure nosing southward down the mid-
atlantic region will edge a weak 'backdoor' cold front farther south
through the night, nearing the altamaha river basin early Sun morning
toward sunrise. Convergence between the low offshore and the ridge
axis nosing southward will bring an increase in rain chances
along the SE ga coast and adjacent waters early Sunday morning
with increasing low level clouds. Cloud cover and shower activity
will funnel southward Sunday, with precip chances increasing
inland through the day with diurnal heating.

Mild above normal temps tonight with low in the low mid 70s
inland to upper 70s near 80 along the coast.

Aviation
Dry conditions this evening at the terminals under ene winds
falling below 10 kts along the coast to light and variable inland
after sunset. Winds near the coast back more nne through the night
as low pressure over south fl tracks NE offshore of the fl
atlantic coast and high pressure ridge axis strengthens southward
over ga. Low stratus and a few coastal showers will approach ssi
and edge down the coast Sunday morning with elevated confidence of
MVFR to potentially ifr conditions impacting ssi crg jax by 15z
sun morning, then farther south toward sgj through midday. Showers
and low stratus will edge inland with daytime heating through sun
afternoon with increasing chances of showers or isolated tstorms
approaching vqq and gnv into the afternoon. Sref NAM guidance
trending toward low stratus shallow ground fog near vqq and gnv
tonight where less cloud cover is expected and advertised MVFR due
to ground fog after 07z.

Marine
Ene winds 10 kts this evening will increase after midnight from
north to south as a front approaches with winds increasing over
the ga waters to 10-15 kts around daybreak with an increase in
showers and isolated thunderstorm potential. Combined seas will
trend 2-3 ft this evening, then increase to 2-4 ft over the outer
waters after midnight. Separated out the ga waters in the forecast
where winds are expected to reach 15-20 kts Sunday (small craft
exercise caution).

Rip currents: moderate risk expected again Sunday.

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.
