Synopsis
High pressure aloft near the west coast and very weak offshore
flow will continue record setting heat today inland from the
beaches. The cooling will spread slowly inland for Friday into the
weekend with greater cooling for Sunday and Monday with stronger
and gusty west winds in the mountains and deserts. There is the
potential for a moderate strength santa ana wind event next
Tuesday into Wednesday with the strongest and most widespread
winds on Tuesday.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

high pressure aloft across southern california will weaken
slightly through Saturday with greater weakening for Sunday and
Monday as a trough of low pressure moves inland along the west
coast and into the great basin.

Record setting heat will continue today away from the beaches
where a return of weak onshore flow will bring some cooling. The
slow cooling developing near the beaches today will spread slowly
inland through Saturday with greater cooling for Sunday and Monday
as the low pressure system moving inland along the west coast
brings stronger onshore flow for southern california with gusty
west to southwest winds for the mountains and deserts.

As that low pressure system moves inland... High pressure aloft
will develop along the west coast with surface high pressure over
the great basin. A period of moderate strength santa ana winds is
possible for Tuesday... Weakening some on Wednesday. There remain
some timing and intensity differences among the global models.

Those winds combined with a very dry air mass could bring critical
fire weather conditions for Tuesday and Wednesday with the
strongest winds on Tuesday.

Aviation
231010z... Mostly clear with unrestricted vis through Friday morning.

Marine
No hazardous marine weather is expected through Monday.

Fire weather
Elevated fire weather conditions will continue today for inland
areas with lowest humidities around 15 percent. Northeast winds
near the coastal foothills will be weaker than on Wednesday with
gusts mostly 30 mph or less this morning. Humidities will slowly
recover for Friday through the weekend.

For next Tuesday and Wednesday... A moderate strength santa ana
wind event is possible with lowest daytime humidities of 5 to 10
percent... And with the strongest and most widespread northeast
winds on Tuesday.

Climate
Forecast high temperatures that could be near or exceed existing
record high temperatures through thanksgiving...

for today...

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.
