.SYNOPSIS...

PRODUCE AREAS OF LIGHT RAIN AND DRIZZLE TONIGHT AND MONDAY MORNING
WEST OF THE MOUNTAINS. IT WILL BE WINDY IN THE MOUNTAINS AND
DESERTS. ON WEDNESDAY AND THURSDAY...HIGH PRESSURE ALOFT WILL BRING
DRY...WARMER WEATHER AND WEAK OFFSHORE FLOW. ANOTHER LOW PRESSURE

FULLERTON...RIVERSIDE...SANTA ANA...AND NORTH ISLAND. FARTHER
UPSTREAM LIGHT RAIN HAS BEEN FALLING ACROSS SANTA BARBARA AND L.A
COUNTIES SINCE 00Z. RAIN TOTALS IN THESE AREAS HAVE BEEN LIGHT SO
FAR THIS EVENING WITH ONLY A 0.01-0.10".

A SURFACE TROUGH OVER CENTRAL CA WILL MOVE SOUTH
OVERNIGHT...DEEPENING THE LOW LEVEL MOIST LAYER TO 8-9KFT WITH LIGHT
RAIN AND DRIZZLE ACROSS OF ORANGE...SAN BERNARDINO...RIVERSIDE AND
SAN DIEGO COUNTIES BY DAYBREAK. THE RAIN WILL TAPER OFF BY 18Z
MONDAY AS THE FRONT WASHES OUT. PRECIP AMOUNTS WILL RANGE FROM ONLY
A FEW HUNDREDTHS TO A TENTH OF AN INCH IN THE COASTAL AREAS...TO
0.10-0.25 IN THE VALLEYS. THE GREATEST TOTALS WILL BE OVER THE
MOUNTAINS FROM OROGRAPHIC LIFT WHERE INCREASING WEST WINDS FROM
30-40 KT 850 MB WIND NORMAL TO THE MOUNTAINS WILL SQUEEZE OUT FROM
0.25-0.50" OF PRECIP. AFTER 18Z THE WINDS BEGIN TO DIMINISH AND
SHIFT TO THE NORTHWEST BRINGING AN END TO THE PRECIP IN MOST AREAS.
THE SHOWERS WILL LINGER LONGEST OVER THE MOUNTAINS INTO THE

WHILE THE JET CORE WILL REMAIN WELL NORTH WITH THE EVENT...THE
SOUTHERLY EDGE OF THE JET WILL BE STRONG ENOUGH TO SUPPORT STRONG
WINDS OVER OUR MOUNTAINS AND HIGH DESERTS TONIGHT AND MONDAY. HAVE

FOR THESE AREAS. THE WINDS WILL DECREASE MONDAY NIGHT.

ON TUESDAY WE BEGIN TO TRANSITION TO A WEAK OFFSHORE FLOW PATTERN.

BUILDS ALOFT. WEDNESDAY AND THURSDAY WILL BE DRY...WARMER DAYS WITH
TEMPERATURES CLIMBING ABOVE AVERAGE FOR A CHANGE. OFFSHORE PRESSURE
GRADIENTS WILL NOT BE OVERLY IMPRESSIVE...BUT STRONG ENOUGH TO
GENERATE MODEST EASTERLY WINDS OF 15-25 MPH THROUGH THE MOUNTAIN
PASSES.

ANOTHER PACIFIC TROUGH WILL DEEPEN OFF THE COAST THURSDAY THEN MOVE
INLAND LATE FRIDAY AND SATURDAY. MODELS DIVERGE ON WHERE THE MAIN
ENERGY FROM THIS SYSTEM WILL MAKE LANDFALL...WHETHER IT BE IN
CENTRAL OR SOUTHERN CALIFORNIA...BUT IS STRONG ENOUGH TO WARRANT A
MENTION A CHANCE FOR SHOWERS.
