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

Visible satellite at 9 AM was showing areas of low clouds clearing
from the valleys. Low confidence in complete clearing at the beaches
this afternoon, with partial and intermittent clearing most likely.
Low clouds and fog are expected to remain persistent each night and
morning for the coast and into portions of the valleys into next
week.

High pressure will build from the south this weekend bringing an
increase in high temperatures, peaking on Sunday. Highs today will
be a few degrees warmer for the coast and valleys with not much
change for the deserts. By Sunday, high temperatures will be around
5 degrees above average near the coast and 10 degrees above average
further inland. NBM chances for the low desert to exceed 115 degrees
on Sunday is less than 10 percent, with an over 90 percent chance of
high exceeding 110 degrees. West of the mountains, there is a 50 to
80 percent chance of portions of the Inland Empire exceeding 100
degrees and a 30 to 50 percent chance of the eastern San Diego
County valleys exceeding 100 degrees Sunday.

A low pressure system moving inland through California on Monday
will strengthen onshore flow for Monday and Tuesday. This will
result in a slight increase in westerly winds over the mountains and
into the deserts. In addition, slight cooling will spread inland on
Monday and Tuesday. By Tuesday high temperatures will be around 5
degrees above average. Wednesday will see a few degrees of warming
as the ridge rebounds in the wake of the passing trough with cooler
conditions expected Thursday and Friday as a stronger, deeper trough
digs into the Pacific Northwest.
