.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

.SHORT TERM (Today through Thursday)...
Weak upper level low pressure moving inland across southern
California will bring high clouds today. Patchy low clouds and fog
have developed along the San Diego County coast beneath a strong
and shallow marine inversion with the low clouds and fog extending
locally inland. Low clouds and fog have briefly extended locally
inland into Oceanside and Carlsbad with the fog briefly dense at
Carlsbad.

For tonight into Wednesday morning, greater coverage and
inland spread of the coastal low clouds and fog is expected as the
marine layer slowly deepens with the low clouds spreading into
the western valleys for early Wednesday. The marine layer is
expected to begin decreasing in depth for Wednesday night into
Thursday morning with the low clouds not extending quite as far
inland as the lower level flow trends weakly offshore.

High temperatures today for the lower deserts will be a few
degrees warmer than Monday, to around 80, with other areas mostly
a few degrees cooler. Cooling will continue for the coast into the
valleys on Wednesday with high temperatures for valleys mostly in
the mid 60s to mid 70s. High temperatures for the coast and
valleys will warm a few to around 5 degrees on Thursday, mostly
into the upper 60s to upper 70s for the valleys.

&&

.LONG TERM (Friday through Monday)...
For Friday and Saturday, high pressure aloft and weak offshore
flow will bring warming and inland drying with high temperatures
for inland areas 10 to locally 15 degrees above average, into the
mid 70s to mid 80s for the valleys, and around 80 for the lower
deserts. High pressure will begin to weaken on Sunday with a low
pressure system from the northwest bringing cooler and breezy
conditions for early next week.
