.SYNOPSIS...
Above average temperatures will continue for inland areas through
Wednesday with a gradual cooling expected Thursday through Saturday.
A warming trend will return for early next week. Breezy westerly
winds expected on the desert mountain slopes into the deserts each
afternoon/early evening. Low clouds will be persistent for the coast
and western valleys each night and morning, becoming more widespread
Friday into the weekend.

&&

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

At 1 PM, temperatures were running up to 5 degrees cooler than this
time yesterday for the inland valleys, with some places along the
coast a degree or two warmer. The low deserts are 2 to 5 degrees
cooler than this time yesterday. Highs tomorrow are expected to be a
few degrees cooler than normal for most places west of the
mountains, but still up to 5 degrees above average for the deserts.
Low clouds this afternoon are locally lingering at area beaches. Low
clouds and fog are expected to spread back inland overnight,
reaching into the western valleys.

An upper level trough will settles over the West Coast on Thursday.
The trough is expected to remain in place into early next week. This
will result in below average temperatures for the end of the week
along with breezy westerly winds on the desert mountain slopes into
the deserts and a deeper marine layer.

Early next week the ridge of high pressure to our east may begin to
strengthen and move back towards Southern California. That will
bring another round of gradual warming Sunday through Tuesday. There
remains some uncertainty in the position of the ridge as it settles
over the desert southwest. The overall position of the ridge will
determine how hot it will get and if any monsoonal moisture will be
allowed into our area. Latest ensemble guidance does not have any
precipitable water increases or notable precipitation chances until
at least the end of next week.
