DISCUSSION:

A LOW PRESSURE SYSTEM SOUTHWEST OF LOS ANGELES COUNTY WILL MOVE
ACROSS THE AREA TODAY BRINGING A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS TO THE VENTURA AND LOS ANGELES COUNTY MOUNTAINS. THERE
IS A POSSIBILITY THAT SOME OF THIS ACTIVITY WILL DRIFT SOUTHWARD
ACROSS WESTERN VENTURA AND FAR EASTERN SANTA BARBARA COUNTIES LATER
THIS AFTERNOON AND EVENING. RAINFALL AMOUNTS WILL BE VERY
SPOTTY...HOWEVER A FEW LOCATIONS COULD SEE BRIEF HEAVY RAIN IN THE
MOUNTAINS DURING THUNDERSTORM ACTIVITY.

THERE IS A SLIGHT CHANCE OF RAIN SHOWERS JUST ABOUT ANYWHERE ACROSS
SOUTHWESTERN CALIFORNIA WEDNESDAY AFTERNOON THROUGH FRIDAY.

HIGH PRESSURE WILL BUILD OVER THE REGION THIS UPCOMING WEEKEND FOR
DRY AND WARMER WEATHER CONDITIONS.

RAINFALL TOTALS THIS WEEK WILL RANGE FROM A FEW HUNDREDTHS UP TO 0.50
INCH OR MORE NEAR SLOW-MOVING THUNDERSTORMS.
