Synopsis
Scattered showers will occur at times through Thursday, with mostly
light rain. Fair and warmer weather will return Friday followed by
cooling over the weekend and yet another trough of low pressure
which will likely bring showers Sunday and Monday. Fair warmer
weather will return again by the middle of next week.

Discussion For extreme southwestern california including
orange... San diego... Western riverside and southwestern san
bernardino counties...

precipitation has mostly ended at mid-evening with just a few
lingering showers. Models show continued showers overnight and
Thursday, mostly light, and the thunderstorm threat is now over. An
inch or two of snow fell in some mountain locations as the snow
level was as low as around 5500 feet late this afternoon and early
this evening, but only minor additional snow is expected. Due to
warming aloft, the snow level will increase to around 7000 feet
Thursday.

From previous discussion...

the trough axis passes through this evening with scattered showers
tonight into Thursday in the cold, moist, and unstable air behind
the trough. Thursday will be another cool day with below average
temps in the valley, mountain and desert zones. Friday and Saturday
will be a little warmer, but it will still be below average.

On Sunday and Monday another deep trough forms over the west.

Embedded shortwaves rotating around the closed low will bring
chances for more showers Sunday and Monday. The stagnant trough
pattern over the west means temperatures will remain below average
through early next week.

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.
