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

THE WIND ADVISORY HAS BEEN DISCONTINUED...

A WINTER STORM WARNING CONTINUES OVER THE MOUNTAINS THROUGH 3 AM PST...

SHOWERS CONTINUE ACROSS MAINLY SOUTHERN PORTIONS OF THE CWA...WITH A
DECREASING TREND EXPECTED AFTER MIDNIGHT...

SCATTERED SHOWERS CONTINUED ACROSS PORTIONS OF ORANGE...RIVERSIDE...
AND SAN DIEGO COUNTIES AT 830 PM PST. SHOWERS WERE MOST NUMEROUS IN
SAN DIEGO COUNTY. PRECIP WAS MOSTLY LIGHT WITH A FEW HEAVIER EMBEDDED
CELLS. THE 00Z MIRAMAR SOUNDING HAD A STEEP LAPSE RATE BELOW 5000 FT
AND A FCST PARCEL CAPE VALUE OF 453 J/K. PW WAS ONLY 0.49 INCH AND
WINDS WERE WNW 25-30 KT IN THE 3-14K FT LAYER. SURFACE PRESSURE
GRADIENTS HAVE TURNED OFFSHORE FROM SW NV BUT REMAIN VERY WEAK
ONSHORE TO THE LOWER DESERTS WITH A STRONG OFFSHORE TREND. THE WINDS
HAVE DECREASED BELOW ADVISORY CRITERIA MOST AREAS WITH MAXIMUM
GUSTS...EVEN IN WIND-PRONE AREAS BELOW 35 MPH.

BASED ON SATELLITE IMAGERY AND RADAR ECHOES AT 03Z...IT APPEARS THERE
IS A 500 MB LOW CENTER JUST OFF THE ORANGE COUNTY COAST. THIS IS
SLOWER THAN THE 12Z GLOBAL MODELS WHICH HAD PLACED THE CENTER NEAR
THIS LOCATION AT 00Z. THIS MAY RESULT IN PRECIP LINGERING IN SAN
DIEGO COUNTY WELL INTO THE NIGHT BEFORE ENDING. SEE THE LATEST
LAXRRMSGX FOR RAINFALL TOTALS HEADLINED IN OUR WEBSITE.

UPPER-LEVEL WINDS WILL SHIFT TO NORTHERLY ONCE THE UPPER LOW DIVES
FAR ENOUGH SE INTO MEXICO. GUSTY NORTHERLY WINDS WILL DEVELOP ALONG
THE COASTAL MOUNTAIN SLOPES AND IN THE FOOTHILLS OF SAN BERNARDINO
AND RIVERSIDE COUNTIES TUESDAY MORNING...WITH GUSTS OF 40 MPH OR MORE
POSSIBLE. HIGH PRESSURE WILL BUILD OVER THE REGION TUE THROUGH THU...
BRINGING FAIR AND WARMER DAYS. TEMPERATURE SHOULD BE BACK ABOVE
AVERAGE BY WEDNESDAY.

COOLER FRI INTO THE WEEKEND AS ANOTHER SHORTWAVE TROUGH APPROACHES
THE CA COAST AND MOVES ONSHORE WITH ANOTHER CHANCE FOR RAIN. THERE IS
CONSIDERABLE DIFFERENCE IN MODEL SOLUTIONS REGARDING THE STRENGTH OF
THIS SYSTEM...SO CONFIDENCE IS LOW REGARDING HOW MUCH RAIN/SNOW WE
MAY GET. HEIGHTS/THICKNESS REMAIN DEPRESSED THROUGH EARLY NEXT WEEK
AS ANOTHER TROUGH ARRIVES...BUT ONCE AGAIN MODELS DIFFERENCES
PRECLUDE ANY CONFIDENCE IN TIMING AND STRENGTH OF THE SYSTEM.
