Aviation...

based on model soundings, 850mb winds expected to become more sw
toward morning, and some of the MOS guidance trends, am going to
go a bit more optimistic (not as low or frequent) on the fog and
lower ceilings. Confidence is increasing in this because right now
the fog channel on satellite is not showing much on cloud fog and
the same is true on the area metars. Thus, am going withVFR
conditions with tempo MVFR conditions all terminals. We could have
borderline wind shear at kvct if winds totally decouple but will
hold off on that since the terminal forecast there does have some
near surface wind and the jet is forecast to be around 30 knots
(close but not high enough confidence to put shear in at this
time). Other than that, still have a similar scenario with the
timing of the frontal boundary moving down mainly during the
afternoon and some showers in the vicinity at kcrp. However, did
delay the gusty winds at kali and kcrp until early evening as
think the main gusts will be shortly after sunset when the
pressures really start to rise. Gusty north winds a good part of
the evening after FROPA with mainly skc.

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.
