Synopsis
Fair weather will prevail through next week with areas of night
and morning coastal low clouds and fog. It will be warmer through
Saturday as a high pressure ridge expands over the region, but
then slightly cooler Sunday and Monday as a low pressure trough
moves by to the north and northeast. Warmer weather will return by
the middle of next week as a ridge builds off the west coast.

Discussion For extreme southwestern california including orange...

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

stratus is playing tricks on us this morning. It appears that the
position of the coastal eddy is such that clouds are actually
moving away from the san diego county coast, but still holding
strong over orange county and even inching into the far west part
of the inland empire. A few clouds or patchy radiation fog may
develop along parts of the san diego coast later this morning, but
overall expect the clearing trend to hold. All areas will clear by
mid-morning.

Low level moisture still exists across the low desert where dew
points are still in the upper 50s and low 60s, though the 00z
sounding shows quite a bit of drying at the 850 mb level compared
to yesterday morning. There may be enough residual moisture for
some shallow cumulus over the mountains this afternoon, but
nothing more than that.

Minor warming and drying will take place through Saturday as very
weak ridging builds over so cal. The marine layer will shrink
ever so slightly, with nocturnal low clouds and fog confined to
the coastal areas and far western valleys in san diego county.

A trough passes by well to the north Sunday into early Monday
bringing unnoticeable cooling for the first full day of
astronomical fall (the equinox occurs on Saturday at 654 pm).

Onshore flow will strengthen for gusty afternoon and evening winds
in the mountains and deserts. Tuesday through Thursday we're more
or less wedged between the very expansive trough across the
central u.S. And a cut-off low a few hundred miles off the
northern ca coast, resulting in weak ridging overhead. Both the ec
and GFS shows high pressure building over the northern great
basin by midweek, but it doesn't expand far enough south to give
us any offshore flow. So remains our uneventful weather with high
temps remaining several degrees above normal inland and near
normal along the coast.

Aviation
210900z... Low clouds will cover most coastal areas and far western
valleys by sunrise, except struggle to do so around kcrq and ksan.

Bases will be around 1500 feet msl with tops to 2000 feet. Scatter
out expected by 15-18z. Low clouds will gradually form and cover
coastal areas after 04z this evening with very similar bases and
extent. Otherwise, skies will be mostly clear with unrestricted
visibility today and tonight.

Marine
No hazardous marine weather is forecast through Tuesday.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

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.
