SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
130 PM PST MON NOV 12 2001

COLD FRONT MOVING QUICKLY INTO THE CENTRAL COAST THIS AFTERNOON. HEAVY
RAIN HAS BEEN FALLING THERE SINCE LATE MORNING WITH ISOLATED FLOODING
REPORTED. I EXPECT THESE GENERAL CONDITIONS TO DEVELOP OVER THE
REMAINDER OF THE FORECAST AREA THIS AFTERNOON AND TONIGHT, WITH RAIN
TAPERING OFF FROM THE WEST THIS EVENING. SHOULD BE A FAIRLY QUICK SHOT
(6 HOURS OR SO) OF MODERATE TO HEAVY RAIN WHICH WILL LIMIT THE TOTALS,
BUT AMOUNTS WILL STILL BE QUITE IMPRESSIVE EVEN BY MID-WINTER
STANDARDS (SEE LAXQPSLAX FOR DETAILS ON AMOUNTS). ISSUED A FLOOD
ADVISORY (LAXFLSLAX) FOR CENTRAL COAST ZONES EARLIER TODAY AND WILL
LIKELY HAVE TO EXTEND THESE SOUTH AS THE DAY AND EVENING GOES ON.

WITH FRONT MOVING RAPIDLY AND DECENT NORTHWEST FLOW BEHIND IT, SKIES
SHOULD CLEAR OUT PRETTY QUICK OVERNIGHT WITH JUST PARTLY CLOUDY SKIES
MOST OF TOMORROW. NORTH MOUNTAIN SLOPES AND NORTHERN VALLEYS WILL HAVE
CLOUDS AND A FEW SHOWERS LONGER DUE TO UPSLOPE CONDITIONS, BUT OVERALL
OUR FORECAST AREA WILL BE MUCH DRIER TUESDAY. TEMPS WILL REMAIN ON THE
COOL SIDE, THOUGH WILL HAVE TO KEEP AN EYE ON DEVELOPING OFFSHORE
BREEZES WHICH COULD WARM THINGS UP ALONG THE CENTRAL COAST. FOR NOW
WILL MENTION SOME OFFSHORE WINDS TUESDAY NIGHT AND WEDNESDAY ALONG
WITH WARMER TEMPS AT LOWER ELEVATIONS.

REMAINDER OF THE WEEK SHOULD BE DRY. THE MRF WAS HINTING AT A WEAK
SYSTEM MOVING INTO THE AREA FRIDAY AND SATURDAY, BUT I DONT THINK
WELL SEE ANYTHING MORE THAN SOME CLOUDS FROM IT AND PERHAPS SLIGHTLY
COOLER TEMPS.
