SHOWER OR SOME DRIZZLE TO VENTURA AND LOS ANGELES COUNTIES. DURING
THE AFTERNOON A COLD AND UNSTABLE AIR MASS WILL MOVE INTO THE AREA
AND WILL LIKELY BRING SHOWERS TO THE AREA ALONG WITH A SLIGHT CHANCE
OF THUNDERSTORMS.

FOR TONIGHT AND FRIDAY...A SECOND IMPULSE WILL MOVE ACROSS THE AREA.
AT THIS TIME...THIS SECONDARY IMPULSE WILL LIKELY MISS SAN LUIS

INCH OF RAIN. HOWEVER...ACROSS THE SAN GABRIEL MOUNTAINS AND
FOOTHILLS...AS WELL AS NEAR THUNDERSTORMS...LOCAL AMOUNTS UP TO
AROUND 1.50 INCHES ARE POSSIBLE. DUE TO THE POTENTIAL FOR HEAVY
