Update Updated air quality issues section.

Synopsis
A warming trend will continue through this weekend, and highs
will top out around 4-8 degrees above normal by early next week.

Dry weather continues, except for a slight chance of showers or
thunderstorms near the sierra crest by the middle of next week.

Discussion
Well this has been a very quiet pattern. I call it an spd pattern.

As in see previous discussion. The forecast is locked in right now
and not many run to run or shift to shift changes. We still will
see warming temperatures this weekend and will have a return to
hot triple digit temperatures for parts of the forecast area next
week. We also are still expecting a northward trajectory on
tropical storm ivo that is currently centered just southwest of
the california baja. The remnants of this system are expected to
be pushed into northern california but could create increased
clouds by late next week that may keep temperatures slightly
cooler across the area. There is still a very slight chance of
rain showers and even a thunderstorm for the highest elevations of
the sierra with this influx of remains from the tropical system.

So as you can see not too much has changed. Ok now you can
officially call me a broken record.

Aviation Vfr conditions can be expected over the central
california interior during the next 24 hours.

Air quality issues
On Saturday august 24 2019... Unhealthy for sensitive groups in
fresno and kern counties and sequoia national park and forest.

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.
