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...

the sky was clear over most of the area into early this evening,
but marine layer stratus was beginning to develop along parts of
the coast. 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
190230z... Coast valleys... Stratus, with bases around 1300 ft msl and
tops near 1700 ft msl, will continue to develop along the coast this
evening and push 10-20 miles inland by early Saturday morning. Vis
of 2-4 sm br is expected where low clouds near higher terrain. Low
clouds will clear towards the coast by late Saturday morning, with
vfr conditions expected Saturday afternoon.

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 the weekend. This swell will create surf to 5 ft north of
carlsbad. Moderate to high 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 remains in effect
through Sunday evening.

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.
