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

.Morning Update...

Low clouds have filled in much of the coastal basin this morning
with thinning high clouds over the region. We`ll be taking
yesterday and pasting it into today as clouds retreat back toward
the coast with filtered sun closer to the beaches. HREF cloud
cover forecasts continue to indicate a similar cloud pattern to
yesterday, with best chances for San Diego beaches to stay under
the clouds much of the day. The forecast remains on track for
Sunday to be the hottest day overall with locally high heat risk
across the lower deserts with moderate to high chances of daytime
temperatures rising over 110 degrees.

.Previous Discussion (309 AM Thursday)...

.SHORT TERM (Today through Saturday)...
The marine layer remains around 2000 feet deep. However cloud
bases are lower with the depth of the saturated cloud layer a
little deeper than 24 hours ago.

Not much change in high temperatures is expected through Friday
with high temperatures around average for the coast and valleys
and around 5 degrees above average for the deserts. High
temperatures through Friday will range from around 70 near the
coast to the 80s and lower 90s for the Inland Empire with 104 to
108 for the lower deserts. High pressure to the south will bring
warming of a few to around 5 degrees for Saturday.

&&

.LONG TERM (Sunday through Wednesday)...
High pressure to the south will continue the warming through
Sunday with Sunday high temperatures 5 to 10 degrees above
average. High temperatures on Sunday will range from the lower
70s near the coast to the upper 80s to upper 90s for the Inland
Empire with 110 to 114 for the lower deserts.

Stronger onshore flow and slight weakening of high pressure aloft
will spread cooling inland on Monday and Tuesday with Tuesday
high temperatures around average to a few degrees below average.
High temperatures on Tuesday will range from around 70 near the
coast to the 80s to around 90 for the Inland Empire with 104 to
108 for the lower deserts. Then warming on Wednesday to around 5
degrees above average for the mountains, deserts, and inland
valleys.

A marine layer near 1500 to 2000 feet deep on Sunday may deepen to
around 2000 to 2500 feet on Tuesday with night and morning coastal
low clouds spreading farther into the valleys.
