Near record warmth expected this weekend...

Dense fog possible again over inland areas late tonight...

Update
Last of atlc gulf coast sea breeze fronts actually meeting up over
inland north fl just west of i-75 and triggering a few light
showers across gilchrist, suwannee and hamilton counties.

Otherwise mostly clear skies this evening with sfc winds becoming
near calm overnight and in the moist low level airmass underneath
the high pressure ridge aloft, this will support another night
with areas of dense fog potential over inland areas with some
patchy areas of fog closer to the coast. Dense fog advisories may
be required towards morning. Lows near 60 degrees inland and lower
60s near the coast. High pressure ridge remains over WRN atlc with
warm southerly flow over the area. Near record warmth expected
with highs well into the lower middle 80s inland and will
challenge daily record highs again. Cooler SE flow at the coast
will have the beaches top out in the upper 70s there. Enough
moisture to continue isolated showers over the coastal waters and
possibly trigger some widely scattered showers over inland NE fl
as gulf atlc coast sea breeze fronts meet again during the mid-
late afternoon hours.

Aviation
Vfr this evening with mainly clear skies. Dense fog and lifr conds
best chances at gnv vqq, with ifr potential at jax crg and lesser
chances of ifr at ssi sgj. All of these conds will develop in the
06-09z time frame and peak btwn 09-13z, with improving back toVFR
after 14z on Saturday in diurnal heating. Any rain chances still
too low (less than 20%) to include in the TAF forecast for sat
afternoon at this time.

Marine
E-se winds 10-15 knots with seas 3-6 ft will continue tonight with
scec headlines for the offshore waters due to seas. High pressure
will build further offshore with winds becoming SE on Sat and S by
sat night and Sunday.

Rip currents: moderate risk in the onshore flow.

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.
