Synopsis
A weak trough of low pressure near the california coast will
continue the slow cooling trend and slow deepening trend of the
marine layer into Friday with not much change for Saturday. Areas
of night and morning low clouds will spread into portions of the
inland values and may be slow to clear in the afternoon for some
coastal areas. For Sunday through Wednesday, strengthening high
pressure to the east will bring an influx of monsoonal moisture
with increasing humidity for inland areas. Chances for
thunderstorms, mainly near the mountains during the afternoons and
early evenings, will begin around Monday. The marine layer will
become shallower for Sunday through the middle of next week with
night and morning coastal low clouds patchier and not spreading as
far inland.

Discussion For extreme southwestern california including orange...

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

Short term (today through Saturday)
The weak trough of low pressure near portions of the california
coast will continue the slow cooling trend and slow deepening of
the marine layer into Friday with not much change for Saturday.

Areas of night and morning coastal low clouds will spread into
portions of the inland valleys. Afternoon clearing may continue to
be slow near some portions of the coast.

Long term (Sunday through Wednesday)
High pressure centered over colorado and utah will strengthen and
expand into the southwest states. This will bring an influx of
monsoonal moisture beginning Sunday and continuing through the
middle of next week. Chances for thunderstorms, with greater
chances near the mountains during the afternoons, will begin
around Monday. There remain differences among the global models
and their ensemble members with the placement and orientation of
the high pressure, which will impact the details of the moisture
influx and resulting thunderstorms chances.

The marine layer will become shallower with night and morning
coastal low clouds becoming patchier and not extending as far
inland. High temperatures in the valleys will warm as the marine
layer becomes shallower. Nights will generally be warmer. High
temperatures elsewhere for inland areas will be modulated by the
monsoonal moisture and cloud cover, but will generally be not
quite as hot.

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.
