Discussion For extreme southwestern california including orange...

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

Short term (today through Friday)
Satellite imagery shows only a few patches of low clouds over the
coastal waters with any low clouds near the coast early this
morning being patchy at most. With high pressure aloft and
weakening offshore flow, high temperatures today are expected to
be a few degrees warmer than Tuesday.

Lower level flow will turn onshore tonight and strengthen on
Thursday. This will bring stronger and gusty southwest to west
winds in the mountains and deserts for Thursday afternoon and
evening with strongest gusts to around 45 mph.

The lower level flow will turn briefly northerly for Friday
morning with gusty north winds to 30 mph along the coastal slopes
of the san bernardino county mountains and below the cajon pass.

A greater return of night and morning low clouds is expected with
the low clouds spreading inland into the western valleys for late
tonight into Thursday morning and into portions of the inland
valleys for Thursday night into Friday morning.

High temperatures on Thursday will be 10 to 15 degrees cooler than
Wednesday with slight warming on Friday.

Long term (Saturday through Tuesday)
Onshore flow on Saturday will become northerly offshore an Sunday
and northeasterly for Sunday afternoon into Tuesday morning. The
winds are expected to be strongest from late Sunday night through
much of the day Monday with stronger gusts to around 45 mph. The
winds will weaken and decrease in coverage for Monday night and
Tuesday.

Slow warming will continue on Saturday with greater warming for
Sunday through Tuesday.

small craft. Some wind gusts in the outer waters could exceed 20 kts
late Thursday.

inland valleys and coastal slopes of the mountains with lowest
daytime humidity around 15 percent and with locally gusty east

southwest to west winds in the mountains and deserts during
Thursday afternoon and evening with strongest gusts to around 45
mph.

There will be a brief period of northerly offshore flow on Friday
morning with gusty north winds on the coastal slopes of the san
bernardino county mountains and below the cajon pass with
strongest gusts to around 35 mph. The lowest daytime humidity for
those areas will fall to 15 to 20 percent, but be after the period
of the gusty north winds.

Northerly offshore flow will develop on Sunday and strengthen,
becoming northeasterly for late Sunday into Tuesday. The strongest
and most widespread northeast winds are expected from late Sunday
night into Monday afternoon with the winds weakening and
decreasing in coverage for Monday night into Tuesday morning.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
