Mostly cloudy with isolated light showers from the coast to the
mountains, but most likely in san diego county. This small chance
of light showers will continue through early Friday morning.

Brisk winds are also likely Thursday, especially in the mountains
and deserts. A fair and warmer weekend is expected before low
pressure returns next week for more cold weather and another
chance of showers.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino

isolated light showers continue to move east this afternoon.

Current temperatures are mostly in the 50s west of the mtns, and
winds continue onshore with few locations reporting gusts of 20
mph or greater.

The long wave pattern over the globe has the western u.S.

Dominated by a longwave trough. Shortwaves will rotate through
southern california within this longwave trough for at least the
coming week. The first wave bringing us the clouds and light
showers today will continue moving eastward into arizona. Expect
light showers anywhere in the coastal basin and into the coastal
slopes of the mountains through this evening, tapering off
overnight. The second wave moves in from the north on Thursday,
bringing a similar precip scenario, but this wave has more dynamic
energy, so precip chances continue into early Friday along with
stronger west winds in the mtns and deserts. Both these waves
favor san diego county for the best chances of measurable precip.

The snow level will be low, around 3500 to 4000 feet, but
accumulations will be very light. The winds will be quite strong
in the mountains and deserts Thursday and Thursday night. The
winds weaken and turn offshore Friday morning to flush out the
clouds and precip. Weak offshore flow will continue through the
weekend for fair weather, although with cool days and cold nights
(not as cold as our last two nights, however). Next week, a third
wave reaches the west coast with more moisture than the previous
two. This has some promise for significant precipitation, but the
timing and strength discrepancies between models keep confidence
low. Either Monday or Tuesday we can expect gusty west winds and

212055z... Sct-bkn clouds with bases 3500-5500 ft msl and layers to
10000 ft msl with iso showers over west of the mountains through
about 00z. Some clearing is expected this afternoon, then clouds
will become bkn-ovc with bases lowering to around 2500-4000 ft msl
with tops to 7000 ft msl overnight. Light showers redeveloping early
Thursday morning. Coastal mountain slopes remaining partially
obscured in clouds precip through Thursday.

No hazardous marine conditions are expected through Thursday
morning. West to northwest winds with gusts 20-30 kt and combined
seas of 8-9 ft with steep waves will develop Thursday afternoon
through Friday evening. This will create hazardous boating
conditions. A small craft advisory will be in effect from 2 pm
Thursday through 8 pm Friday.

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

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
