.DISCUSSION...A STRONG PACIFIC STORM SYSTEM CURRENTLY JUST OFF THE
SOUTHERN CALIFORNIA COAST WILL TRANSITION EAST TODAY AND
IMPACT THE AREA THIS AFTERNOON THROUGH SUNDAY MORNING. LOW/MID LEVEL
CLOUDS WILL DEVELOP AND STRONGER SOUTHWEST WINDS WILL MIX DOWN TO THE
SURFACE BY EARLY AFTERNOON. THERE IS ALSO A CHANCE THAT
WE COULD START TO SEE SOME SNOW AS EARLY AS THIS AFTERNOON...BUT
SNOW DOES NOT LOOK LIKELY UNTIL LATE THIS EVENING. TONIGHT THROUGH
SATURDAY...12 TO 18 INCHES WILL BE POSSIBLE.

20 FT WINDS LOOK TO STAY OUT OF THE SOUTH SOUTHWEST TODAY...WITH
LIMITED UPSLOPE POTENTIAL DUE TO LACK OF SOLAR HEATING. SO EXPECT
SOUTH/SOUTHWESTERLY WINDS TO CONTINUE...INCREASING THIS AFTERNOON.

SNOW AND GUSTY WINDS WILL CONTINUE THROUGH SATURDAY...WITH CONDITIONS
BEGINNING TO IMPROVE SATURDAY NIGHT...BUT THERE WILL STILL BE A CHANCE
SNOW THROUGH SUNDAY AFTERNOON. A  BREAK IN THE WEATHER IS EXPECTED
