.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
RAIN WAS WIDESPREAD FROM THE COAST TO THE DESERTS TODAY. MOST AREAS 
RECEIVED LESS THAN ONE-QUARTER INCH...WITH THE LEAST ALONG THE 
COAST...AND THE MOST IN THE VALLEYS AND MOUNTAINS. THE SAN DIEGO 
COUNTY DESERTS DID QUITE WELL THOUGH WITH SOME AMOUNTS OVER ONE- 
QUARTER INCH. GREATEST AMOUNTS AROUND ONE-HALF INCH FELL ON THE FAR 
INLAND VALLEYS AND MOUNTAINS. THE SNOW LEVEL REMAINED ABOVE 8500 
FEET SO THE WINTER WEATHER ADVISORY FOR THE SAN BERNARDINO MTS HAS 
BEEN CANCELLED.
AFTER A SOMEWHAT SOGGY DAY...THE SHOWERS WERE WINDING DOWN THIS 
EVENING. RADAR SHOWED JUST A FEW LEFT AND THEY WERE MOVING RAPIDLY 
FROM THE SOUTH AT 30-35 MPH...HELPING TO KEEP FURTHER ACCUMULATIONS 
LIGHT. SURFACE PRESSURE GRADIENTS SHOWED STRONG ONSHORE TRENDS BUT 
REMAINED WEAK OFFSHORE FROM THE DESERTS. SOUTHEAST WINDS WERE STILL 
GUSTY AT 25-30 MPH IN SOME MOUNTAIN LOCATIONS. THE 00Z MIRAMAR 
SOUNDING SHOWED NEAR SATURATION IN THE 9K-12K FT LAYER..BUT HAD 
MOISTENED CONSIDERABLY ALL THE WAY DOWN THROUGH 4K FT...HELPING TO 
BOOST THE PW TO NEARLY ONE INCH. SOME IR ENHANCEMENT WAS STILL 
OCCURRING IN SATELLITE IMAGERY...BUT IT WAS WELL NE OF THE CWA.  
BASED ON WATER VAPOR IMAGERY...THE LOW PRESSURE CENTER RESPONSIBLE 
FOR OUR RAINFALL WAS MOVING RAPIDLY NORTHWARD AND WAS CENTERED WELL 
WEST OF SAN CLEMENTE ISLAND AT 04Z. THE LOW SHOULD LEFT NE ACROSS 
CENTRAL CA ON TUE...TURNING OUR WINDS ALOFT BACK FROM THE WEST...
CLEARING OUT MOST OF THE HIGH-LEVEL MOISTURE AND CLOUDS. EVEN WITH 
MORE SUNSHINE...A COOLER AIRMASS WILL BE IN PLACE...AND SOME LOWER 
CLOUDS WILL LINGER...SO TUE WILL BE A BIT COOLER.
A WEAK RIDGE WILL TRAVERSE THE REGION ON WED...FOLLOWED BY A 
DEVELOPING TROUGH FOR THE LATTER HALF OF THE WEEK. THE TROUGH WILL 
ADVECT IN ADDITIONAL MOISTURE BUT IS QUITE WEAK INITIALLY. THE 
MODELS SHOW IT DEEPENING AND DEVELOPING INTO A CUTOFF LOW BY FRI. 
MODELS ALSO SHOW MOISTURE WRAPPING INTO THE CENTER FROM THE SOUTH 
WITH THE BROAD CIRCULATION AROUND IT COVERING SOCAL. SO THERE WILL 
BE A CHANCE OF MOSTLY LIGHT SHOWERS AT TIMES INTO THE WEEKEND AND 
WITH MORE CLOUDS...THE DAYS WILL BE SLIGHTLY COOLER.
WARMER AGAIN LATE IN THE WEEKEND AS THE UPPER LOW SINKS SOUTH AND 
OFFSHORE FLOW DEVELOPS. THE OFFSHORE WINDS MAY BECOME STRONG AND 
GUSTY AGAIN BY SUNDAY...BUT THEN WEAKEN AS THE UPPER LOW DEPARTS AND 
A RIDGE BUILDS ALOFT. THE RIDGE WILL BRING FAIR...DRY...AND WARMER 
DAYS ONCE AGAIN AS WEAK OFFSHORE FLOW PREVAILS AT THE SURFACE EARLY 
NEXT WEEK.
