Stronger and gusty santa ana winds will become more widespread
this morning... Then become less widespread... More easterly... And
not quite as strong for tonight into Wednesday. Near record
setting heat will continue today from the coast into the western
valleys with slight cooling for Wednesday and greater cooling near
the coast on Thursday. Onshore flow for Friday through Monday will
bring slow cooling with a gradual return of night and morning
coastal low clouds and fog.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
Short term (today through Thursday)
Gusty santa ana winds continue early this morning near the coastal
foothills and below passes and canyons with strongest gusts
between 50 and 60 mph. The strongest gust overnight so far has
been 59 mph at fremont canyon in the coastal foothills of the
santa ana mountains... And sill hill in the san diego county
mountains. Where mixing from the winds continues... Temperatures
have remained quite warm... With temperatures still in the 90s in
portions of the western inland empire and inland portions of
northern orange county.
There was record setting heat Monday... Mostly in coastal and
western valley areas. The mostly likely areas to be hotter than
Monday are areas toward the coast as stronger offshore flow pushes
the hotter temperatures for inland coastal areas closer to the
coast with high temperatures in some coastal areas around 25
degrees above average.
Stronger and gusty santa ana winds will continue today... Becoming
more widespread in the morning with east to northeast winds with
gusts to 55 mph and isolated gusts to 65 mph. Winds will become
less widespread... More easterly... And not quite as strong for
tonight into Wednesday.
Not quite as hot for Wednesday as slow cooling begins to spread
slowly inland. Even with the slight cooling... The heat may still
be sufficient to extend the excessive heat warning into Wednesday
for some coastal and valley areas. Weak onshore flow will return
on Thursday with greater cooling for coastal areas into the
Long term (Friday through Monday)
High pressure aloft will remain centered along the west coast for
Friday... Then begin to weaken on Saturday through Monday as a
trough of low pressure moves southeastward through the pacific
northwest into the great basin. This will bring a return of
onshore flow with slow cooling spreading inland. Even with the
cooling... High temperatures on Monday will still be around 5
degrees above average for inland areas. Patchy coastal stratus
will return near the coast and increase in coverage going into
early next week.
240900z... Clear skies today and tonight. Areas of northeast to east
winds 15-25 kt and gusts 35-45 kt will continue into this afternoon.
Strongest winds will be through and below the passes and canyons,|
and on coastal mountain slopes and foothills. This will produce mdt-
stg uddfs and llws over and W SW of the mountains, impacting vcnty
kont, ksbd, kral and ksna at times. Winds will begin to weaken late
No hazardous marine weather is expected through Saturday.
Critical fire weather conditions will continue into Wednesday for
the mountains... Valleys... And orange county. Gusty santa ana
winds will continue through Wednesday... With the strongest and
most widespread winds today. Lowest daytime humidity around 5
percent today and 5 to 10 percent Wednesday. Weaker winds are
expected for Thursday and Friday with slow cooling spreading
inland and with a gradual recovery of humidity.

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.
