Synopsis
Fair and mild weather will continue this coming week, with coastal
clouds extending into valleys during nights and mornings. Monsoon
moisture will bring a slight chance of showers and thunderstorms
to the mountains and desert late Sunday and Monday.

Discussion For extreme southwestern california including orange...

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

sunny skies abound this afternoon, but there are a few cumulus
clouds over the san bernardino mountains. A weak low pressure
trough spinning off the california coast will deepen slightly
this weekend. This will deepen the marine layer, allowing coastal
clouds to extend just a little farther inland for Sunday and
Monday. At the same time, the southerly flow on the east side of
the trough will draw monsoon moisture into southeast california.

So you'll see some afternoon cumulus over the mountains and
deserts. The latest model runs, which now include higher
resolution models, are pointing to at least a slight chance of
showers and thunderstorms late Sunday. A plume of moisture is
shown by models to move from sonora into southern california
mainly north of san diego county Sunday night and Monday. That
will increase the chance of showers and thunderstorms Monday,
even possibly Sunday night through Monday morning in the desert.

It looks like the marine layer will extend the coastal clouds
farthest inland on Monday, but all but the coast should clear out
for best eclipse viewing (provided the higher monsoon cloudiness
doesn't block the view). For those who like mild summer weather,
enjoy this coming week as it appears temperatures will come in a
little below average each day next week.

Aviation
182030z... Coast valleys... Light westerly sea breezes this afternoon
and evening through and 03z. Low clouds with bases near 1500 ft msl
will slowly return to areas within 25 miles of the coast after 03z
Saturday. Look for the low clouds to clear to the coast between 15z
and 17z Saturday, with patchy low clouds lingering over the coastal
waters thereafter through about 03z Saturday evening.

Mountains deserts... Mostly clear skies and unrestricted visibility
will continue through this weekend.

Marine
No hazardous marine weather is expected through Tuesday night.

Beaches
A moderate period south swell (2-3 ft at 200 degrees) will continue
through this weekend. This swell will increase surf, with sets to 5
ft possible north of carlsbad. Moderate strength rip currents will
accompany the surf. Abnormally high tides are also expected this
weekend, each evening, peaking around 7 feet with each high tide,
with minor overflows possible. A beach hazards statement has been
issued.

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

Sgx watches warnings advisories
Ca... Beach hazards statement from Saturday afternoon through Sunday
evening for orange county coastal areas-san diego county
coastal areas.

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.
