...WIND CHILL ADVISORY REMAINS IN EFFECT UNTIL 9 AM PST MONDAY...

&&

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

IT WAS VERY COLD...CLEAR AND DRY OVER THE CWA OVERNIGHT WITH A
NUMBER OF RECORD MINIMUM TEMPERATURES SET ACROSS THE AREA. THESE
MINIMUM TEMPERATURES ALSO HELPED VERIFY THE FREEZE WARNING THAT WAS
IN EFFECT FOR THE COAST...INLAND VALLEYS AND SOUTHERN DESERT AREAS.
THE FREEZE WARNING WAS ALLOWED TO EXPIRE ON SCHEDULE BUT ANOTHER
WILL BE ISSUED FOR TONIGHT FOR THE COLDER WIND SHELTERED AREAS. WIND
WILL DEVELOP LATE TONIGHT BELOW MOUNTAIN PASSES AND CANYONS WHICH
SHOULD HELP MODERATE TEMPERATURES IN THOSE AREAS BUT AREAS THAT DO
NOT RECEIVE THE WIND SHOULD REMAIN QUITE COLD.

THE 12Z NAM IS SIMILAR TO PREVIOUS MODEL RUNS WITH THE SHORTWAVE
MOVING SOUTH THROUGH THE AREA TONIGHT. THIS SHORTWAVE CONTINUES TO
BE A DRY INSIDE SLIDER BUT WILL BE FOLLOWED BY STRONG GUSTY NORTH TO
NORTHEAST WINDS ACROSS THE NORTHERN MOUNTAINS AS WELL AS THROUGH AND
BELOW MOUNTAIN PASSES BY SUNRISE MONDAY MORNING. WILL UPGRADE THE
HIGH WIND WATCH TO A HIGH WIND WARNING WITH THE AFTERNOON PACKAGE
FOR THE INLAND EMPIRE AND THE SANTA ANA MOUNTAINS. WILL INCLUDE A
WIND ADVISORY FOR THE SAN BERNARDINO MOUNTAINS AS WELL. THE WATCH
CURRENTLY EXTENDS INTO MONDAY AFTERNOON BUT THE 12Z NAM SUPPORTS
EXTENDING THIS INTO TUESDAY.

THE 12Z NAM IS ALSO SIMILAR TO EARLIER RUNS WITH THE SHORTWAVE ON
WEDNESDAY BEING A LITTLE FURTHER WEST DROPPING SOUTH ALONG THE
COAST. THIS WILL HAVE A MORE OVER WATER TRAJECTORY RESULTING IN MORE
MOISTURE ACROSS THE AREA ON WEDNESDAY AND THURSDAY. AT THIS TIME IT
APPEARS TO BE MOSTLY CLOUDS BUT SOME SHOWERS ARE POSSIBLE BUT EXPECT
ANY QPF AMOUNTS TO BE LOW. THIS CAN CHANGE TO BEING WETTER SHOULD
THE SHORTWAVE TRACK SOUTH FURTHER OFF THE COAST OR IT COULD BE DRY
SHOULD IT TRACK SOUTH FURTHER INLAND. FOR NOW...WILL NOT MAKE ANY
CHANGES FOR THAT PERIOD.

WILL UPDATE THE FORECAST SHORTLY TO REMOVE THE FREEZE WARNING.
OTHERWISE NO OTHER UPDATES ARE PLANNED AT THIS TIME.
