DISCUSSION:

A DRY WEATHER PATTERN IS EXPECTED THROUGH SUNDAY NIGHT...THEN A COLD
UPPER-LEVEL TROUGH OF LOW PRESSURE WILL DIG INTO THE REGION BETWEEN
MONDAY AND TUESDAY. SHOWERS WILL BECOME LIKELY FOR AREAS NORTH OF
POINT CONCEPTION BY LATE MONDAY...WITH A GOOD CHANCE OF SHOWERS
ACROSS THE ENTIRE REGION MONDAY NIGHT. SCATTERED SHOWERS WILL LIKELY
LINGER ACROSS LOS ANGELES AND VENTURA COUNTIES ON TUESDAY AND ALONG
THE NORTHERN MOUNTAIN SLOPES INTO TUESDAY EVENING.

PRECIPITATION WILL THIS SYSTEM WILL BE SHOWERY IN NATURE AND WILL
WIDELY VARY FROM LOCATION TO LOCATION. AT THIS TIME, RAINFALL TOTALS
OF 0.20 INCH OR LESS WILL LIKELY OCCUR ON AVERAGE IN MOST AREAS.
LOCAL HIGHER TOTALS UP TO 0.33 INCH ARE POSSIBLE, ESPECIALLY ALONG
THE NORTHERN SLOPES OF THE MOUNTAINS AND WHERE HEAVIER SHOWERS
OCCUR. SNOW LEVELS WILL BE LOW...GENERALLY 3500 TO 4500 FEET...AND
POSSIBLY DOWN TO AS LOW AS 2500 FEET.

A MORE SIGNIFICANT STORM IS STILL FORECAST TO BRING RAIN TO THE
REGION LATE NEXT WEEK. THE EXACT TIMING IS VARYING A LITTLE BIT, BUT
MODELS DO AGREE WITH A SIGNIFICANT STORM SOMEWHERE BETWEEN THURSDAY
AND SATURDAY. RAIN COULD DEVELOP AS SOON AS THURSDAY OR THURSDAY
NIGHT AND CONTINUE THROUGH FRIDAY OR SATURDAY. THERE REMAINS LOW
CONFIDENCE IN THE DETAILS OF THE SYSTEM SINCE THE MODELS HAVE BEEN
INCONSISTENT. IT HAS THE POTENTIAL TO BRING WIDESPREAD RAINFALL OF
ONE HALF INCH TO ONE INCH TO COASTAL AND VALLEY AREAS...AND 1 TO 2
INCHES TO FOOTHILL AND MOUNTAIN LOCATIONS.
