Synopsis
A weak trough will bring cooling through Friday. The marine layer
will deepen into Friday with low clouds and fog on the coast and
in the far western valleys. High pressure builds back in this
weekend, warming temperatures slightly. Marine layer clouds will
become shallower this weekend with less inland extent. Monsoonal
moisture makes its way back into socal this weekend, bringing an
increase in humidity, high clouds, and some afternoon cumulus
clouds over the mountains.

Discussion For extreme southwestern california including orange...

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

the coastal eddy is keeping low clouds along the coast this
afternoon as well as gusty winds. San diego airport had a gust to
24 mph around 1pm. Low clouds will move back in a little earlier
tonight than last night.

A weak trough of low pressure will bring cooling through Friday
and a deeper marine layer. The coastal eddy that developed last
night will continue into Friday. Locally dense fog will develop
tonight into tomorrow morning in the valleys. Low clouds could
reach portions of the inland empire by Friday morning.

For this weekend, high pressure builds into california, warming
inland areas to slightly above average. The marine layer will be
a little shallower this weekend and spread less far inland. Only
minor variations in temperatures expected through the middle part
of next week. Monday and Tuesday look like the warmest days in the
coming week.

Monsoonal moisture will make a return this weekend and into next
week bringing an increase in humidity for the inland areas. There
will be high clouds and some afternoon cumulus clouds near the
mountains. It doesn't appear the the moisture increase will be
sufficient enough for afternoon thunderstorms, so chances of
thunderstorms have been kept out of the forecast.

Aviation
222100z... Coast valleys... Sct-bkn CIGS will continue at times along
the immediate coast this afternoon. Mod hi confidence in low clouds
moving back inland 01-03z Friday with bases 600-1100 ft msl, moving
20 mi inland overnight with vis 3-5 sm. Low moderate confidence in
cigs reaching kont later tonight. Scatter out expected around 17z
Friday with patchy CIGS possible again along the coast.

Mountains deserts... Mostly clear with unrestricted visibility
through Friday morning.

Marine
Southerly winds gusting to around 15 knots through this evening.

Otherwise, no other hazardous marine conditions are expected through
Monday.

Beaches
South-southeast swells from 160-170 degrees with a 12-13 sec period
generated by tropical storm ivo will reach the beaches of southern
california late Sunday through Tuesday. There is a chance that these
swells could produce elevated surf of up to 5 ft and strong rip
currents on south-facing beaches of orange county. A beach hazards
statement is in effect for orange and san diego county beaches
Saturday night through Tuesday morning with biggest impacts being
elevated surf and coastal flooding.

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.
