.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
...UPDATED AVIATION DISCUSSION...
.SHORT TERM (Today through Wednesday)...
High temperatures for the deserts into the mountains will warm a
few degrees today with not much change for the coast and valleys.
High temperatures for today for the coast and valleys will be
mostly in the mid 70s to lower 80s and for the mountains in the
50s and 60s.
A gradual cooling trend will begin on Tuesday and continue through
next weekend. High temperatures on Wednesday will be a few
degrees below average near the coast and in the lower deserts to 4
to 8 degrees below average for the mountains and inland valleys.
High temperatures on Wednesday for the coast and valleys will be
mostly in the 70s and for the mountains in the mid 40s to mid 60s.
Coastal low clouds may return for tonight into Tuesday morning
with greater spread into the valleys for Tuesday night into
Wednesday morning. There will be increasing high clouds beginning
around Wednesday.
&&
.LONG TERM (Thursday through Sunday)...
The cooling trend will continue through Sunday with high
temperatures for inland areas next Sunday mostly 10 to 15 degrees
below average. High temperatures for next Sunday will be mostly
in the 60s to around 70 for the coast and valleys and for the
mountains in the mid 30s to mid 50s.
The center of a closed low pressure center will be near the
Pacific Northwest coast for Thursday through Sunday. A nearly
zonal subtropical jet stream from the central and eastern Pacific
into northern Baja will strengthen for Friday and Saturday,
possibly transporting a low pressure into northern Baja into far
southern California some time around late Saturday into Sunday.
ECMWF ensemble output increases precipitable water values in far
southern California to 1.2 to 1.4 inches on Saturday afternoon and
evening, around 200 to 250 percent of normal.
For Thursday through Sunday, the chance for measurable rainfall
will increase each day with chances for greater amounts increasing
during next weekend. For Saturday morning through Sunday night,
The chance of 1 inch or more of rainfall for the coast to the
mountains is greater than 40 percent, and for San Diego County
and the Riverside County mountains 50 to 60 percent. Chances for
