.SYNOPSIS...
Today will be slightly cooler than Wednesday, then warmer for
Friday and Saturday, little or no warming for Sunday and Monday,
then additional warming for Tuesday and Wednesday with high
temperatures on Wednesday of next week 5 to 10 degrees above
average for inland areas. The marine layer will become shallower
for the weekend into next week with night and morning coastal low
clouds spreading into portions of the western valleys late each
night.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
.SHORT TERM (Today through Saturday)...
A low pressure system over southern California early this morning
will weaken as it moves into Arizona today with a faster-moving
low pressure system to the north moving inland through northern
and central California tonight with weakening low pressure across
California on Saturday.
High temperatures today will be slightly cooler followed by
warming on Friday and Saturday with Saturday high temperatures
around average at lower elevations and around 5 degrees below
average for mountain elevations above 6000 feet.
A marine layer near 2000 to 2500 feet this morning with coastal
low clouds spreading into portions of the Inland Empire will
become gradually shallower for Friday and Saturday with night and
morning coastal low clouds not spreading as far into the valleys.
&&
.LONG TERM (Sunday through Wednesday)...
Not much change in high temperatures or slight warming for inland
areas on Sunday and Monday with high pressure over the interior
southwest states, low pressure off the northern California coast,
with generally dry south to southwest flow aloft over southern
California. Some shallow lower level monsoonal moisture could
begin to spread into the lower deserts next week with warmer
nights for the lower deserts and with some afternoon clouds along
the desert slopes of the mountains for the middle of next week.
High pressure aloft to the east will strengthen and expand for the
middle of next week, though with some model differences with the
placement. This will bring additional warming on Tuesday and
Wednesday with high temperatures on Wednesday 5 to 10 degrees
above average for inland areas. High temperatures on Wednesday
will range from the lower to mid 70s near the coast to the mid 90s
to 105 for the Inland Empire with 112 to 116 for the lower
deserts.
