at the beaches this morning. Should be good eclipse viewing all
areas. Still a slight chance of showers & thunderstorms late this
afternoon over the highest peaks of riverside and san bernardino
counties and in the high desert late this afternoon on the very
western fringe of a mid level monsoonal flow from northern sonora.
Please see remainder of the previous discussion below for more
details on the forecast.
A weak low pressure system off the southern california coast will
keep high temperatures a few degrees below average today with
areas of low clouds with patchy fog and drizzle extending into
portions of the inland valleys this morning. Mid level monsoonal
moisture to the east and north will bring some afternoon clouds to
the mountains with a slight chance for thunderstorms for the san
bernardino county mountains and adjacent deserts this afternoon.
There will be warming to near average high temperatures for
Tuesday through Friday... With high pressure over the great basin
bringing warming to 5 to locally 10 degrees above average for next

Satellite imagery shows widespread stratus over the coastal waters

spreading into western and southern portions of the inland
empire. The stratus is expected to cover much of the valleys by

this morning. The coastal stratus is expected to clear back
towards the beaches by late morning.
There are also mid clouds spreading northwestward across the
eastern deserts of southern california with scattered showers over

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.
