Synopsis
A trough of low pressure will continue the cooling trend for
inland areas today. High pressure will expand across california
for the weekend into next week with high temperatures warming to
around average. Coastal low clouds will extend into portions of
the inland valleys this morning, but will not extend as far inland
for the weekend into next week as the marine layer becomes
shallower. A minor influx of monsoonal moisture from the south
will increase the humidity for inland areas for the weekend into
next week. This will bring some high clouds a times and some
afternoon clouds near the mountains, but with minimal chances for
thunder.

Discussion For extreme southwestern california including orange...

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

Short term (today through Sunday)
A trough of low pressure will continue to move inland today across
the western states as it moves toward the central plains. High
pressure over the eastern pacific will expand across california
during the weekend. Cooling will continue today, except near the
coast. Warming will return high temperatures to around average
during the weekend.

The marine layer has deepened to around 2000 to 2500 feet.

Satellite imagery shows widespread coastal low clouds extending
inland across the western two thirds of the san diego county
valleys and just beginning to spread into southern portions of the
inland empire. The marine layer will become shallower during the
weekend with coastal low clouds spreading into the western valleys
for tonight into Saturday morning, and the far western valleys for
Saturday night into Sunday morning.

Some mid level monsoonal moisture will spread into the area during
the weekend as well as some shallow intrusions of low level
moisture in the lower deserts. This will bring some high clouds at
times and some afternoon clouds near the mountains during the
weekend. High pressure aloft will limit instability with chances
for any thunder still minimal.

Long term (Monday through Thursday)
High pressure will remain across the area with high temperatures
remaining around average. Night and morning coastal low clouds
will extend no farther inland than the far western valleys.

Monsoonal moisture and instability will remain marginal for any
thunder.

Aviation

tops to 2100 ft msl will continue to spread up to 25 mi inland this

Marine

Beaches
South-southeast swells from 160-170 degrees with a 12-14 sec period
generated by tropical storm ivo will reach the beaches of southern
california late Saturday, peaking Sunday before lowering Monday and
Tuesday. These swells could produce isolated surf up to 6 ft and
strong rip currents on the more southerly-facing beaches of orange
county, though west facing beaches, mainly in san diego county, will
have little or no effects. A beach hazards statement is in effect
for orange and san diego county beaches Saturday night through
Tuesday morning with biggest impacts being strong rip currents and
longshore currents.

encouraged to report significant weather conditions.

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.
