.SYNOPSIS...
Fair and mild weather will continue this coming week, with
coastal clouds nights and mornings.

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

Sunny skies dominated the weather picture this afternoon. And it`s
a little warmer than it was yesterday at this time. The marine
layer and onshore flow should stabilize better than it was this
morning for a more uniform coastal cloud deck tonight, and
coastal clouds/fog could reach into the westernmost inland
valleys. Copy and paste this idea for the coming seven days and
your forecast should be pretty accurate. The day to day
fluctuations in cloud coverage and temperature will be too subtle
to notice unless you`re really paying attention. We are paying
attention around here, so we`ll mention that a very weak trough
develops Sunday and Monday that will probably push nocturnal
coastal clouds a little farther inland and bump temps downward a
few degrees. For the entire coming week we see no credible hint
from models about any monsoon flow. That will mean mostly clear
skies (except for the nocturnal coastal clouds), along with dry
and mild weather with temps a little under August averages.
