DISCUSSION:
FAST MOVING COLD FRONT CONTINUES TO BRING SCATTERED SHOWERS TO
PORTIONS OF VENTURA AND LOS ANGELES COUNTIES THIS
AFTERNOON...ESPECIALLY IN THE MOUNTAINS. AS THE FRONT MOVES EASTWARD
INTO LOS ANGELES COUNTY THIS AFTERNOON...THERE WILL BE SOME CYCLONIC
FLOW ALOFT THAT WILL HELP TO MAINTAIN SCATTERED SHOWER
ACTIVITY...ESPECIALLY IN THE SAN GABRIEL MOUNTAINS AND ADJACENT
FOOTHILLS. BY THIS EVENING...MOST OF THE SHOWER ACTIVITY WILL BE
CONFINED TO NORTH FACING SLOPES OF THE MOUNTAINS. SNOW LEVELS WILL
CONTINUE TO RANGE BETWEEN 6000 AND 7000 FEET.

ANY ADDITIONAL RAINFALL THAT SHOULD FALL WITH THIS SYSTEM SHOULD
GENERALLY BE FAIRLY LIGHT...WITH RATES MOSTLY LESS THAN .10 INCHES
PER HOUR. HOWEVER...ISOLATED RATES UP TO .25 INCHES PER HOUR WILL
STILL BE POSSIBLE FOR THE MOUNTAINS OF LOS ANGELES COUNTY. FOLLOWING
THE PASSAGE OF THIS SYSTEM...AN EXTENDED PERIOD OF WARM AND DRY
WEATHER IS EXPECTED THROUGH AT LEAST THE MIDDLE OF NEXT WEEK.
