Discussion
Lowered temperatures a few degrees for the update. Think they'll
eventually level off, but t TD spread is far enough apart to allow
for them to fall a bit. Otherwise, current forecast is in pretty
good shape. Other than some iso shra and possibly -dz in the
morning, capping should keep TSTM chances in check until later in
the day Saturday and Saturday night. 47

aviation...

deepening moisture from the gulf along with disturbances from the
west is helping to produce areas of patchy light rain drizzle and
perhaps slightly lower CIGS from the west. This current band will
be moving off to the east later this evening, with the next batch
timed for the overnight early morning hours (based on satellite).

Mostly MVFR CIGS are expected areawide overnight but given the
in- creased low-level winds at and just above the surface, not
expecting any fog lower vis or extended periods of lower cigs.

Isolated WAA shra possible along the coast but activity should
increase by the afternoon with daytime heating and the approach of
the front. Will likely keep the mention of precipitation in the
tafs through Saturday evening... With things tapering off behind
the front from W to E overnight Saturday into Sunday. 41

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.
