Update Updated air quality issues section.
Warming trend over the next few days as a ridge of high pressure
anchors itself over the forecast area. Temperatures will remain
above average through next week. Expect afternoon highs on Monday
through Wednesday to be around 5-10 degrees above average. Slight
chance of a few afternoon evening showers and thunderstorms over
the sierra crest midweek.
Visible satellite imagery shows mainly sunny skies across the
central california interior with just a few cumulus popping over
the sierra nevada. 24 hour trends show temperatures are generally
at to a couple degrees lower than yesterday. High temperatures in
the san joaquin valley will top out mostly in the upper 90s today
with a few locations reaching the century mark. A ridge of high
pressure will strengthen over the region for a warming trend the
next few days. Triple digit highs will become more widespread in
the sjv, lower foothills, and desert. Maximum temperatures are
forecast to be around 5-10 degrees above climatological normals
Monday through Wednesday. An upper trough is expected to weaken
the ridge a little later in the week as it approaches the pacific|
northwest coast. This will nudge temperatures back downward but
are still expected to be a little above normal.
Water vapor imagery show tropical storm ivo spinning west of the
southern tip of baja california. Ivo is forecast to weaken to a
tropical depression by Sunday as it slowly moves to the north-
northwest. The remnants are forecast to track northward to just
west of the central california coast by Tuesday and then inland
over northern california on Wednesday. There may be just enough
moisture and instability to produce some isolated showers and
thunderstorms over the sierra nevada tues-wed. Otherwise, dry
conditions will continue over the forecast area.
Aviation Vfr conditions can be expected over the central
california interior during the next 24 hours.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
