WESTERN SLOPES OF THE MOUNTAINS THIS MORNING. FAIR AND MILD WEATHER
WILL CONTINUE FOR SEVERAL DAYS AS HIGH PRESSURE REMAINS OVER THE
WEST COAST. COOLER WEATHER AND STRONG OFFSHORE WINDS WILL DEVELOP

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

SOME OFFSHORE WINDS CONTINUE BUT GUSTS ONLY INTO THE 20-30 MPH
RANGE. THE GRADIENT TURNS MORE EASTERLY FOR TONIGHT WHICH WOULD
DISFAVOR CAJON PASS A LITTLE AND FAVOR WINDS THROUGH EAST-WEST
PASSES IN RIVERSIDE AND SAN DIEGO COUNTIES AND MAY NEED A WIND
ADVISORY FOR THOSE AREAS. OTHERWISE...FAIR FOR A FEW DAYS BUT COOLER
STARTING SUN AS THE UPPER HIGH OVER THE WEST COAST BREAKS DOWN A
LITTLE AND RETREATS TO THE OCEAN. THIS PUTS SOCAL IN NORTH OR
NORTHWEST FLOW. SHORTWAVES MOVING THROUGH THE HIGH TUE AND LATER WED
WILL ENHANCE OFFSHORE FLOW BY DRAWING COLD AIR INTO THE GREAT BASIN.
THIS WILL MEAN OFFSHORE WINDS WILL PICK UP AGAIN TUE THROUGH THU AT
LEAST. AND NO RAIN IN SIGHT THROUGH CHRISTMAS WEEKEND.
