DISCUSSION...
HIGH PRESSURE OVER CALIFORNIA WILL BRING DRY WEATHER THROUGH
WEDNESDAY.

FOR LATE WEDNESDAY NIGHT THROUGH EARLY NEXT WEEK...A SERIES OF
PACIFIC STORMS ARE EXPECTED TO BRING SIGNIFICANT PRECIPITATION TO
SOUTHERN CALIFORNIA. THERE REMAIN SOME DIFFERENCES IN THE TIMING
AND INTENSITY OF EACH STORM. THE FIRST STORM IS EXPECTED FOR LATE
WEDNESDAY NIGHT AND THURSDAY...A SECOND FOR FRIDAY...A THIRD FOR
SATURDAY...AND A FOURTH FOR LATE SUNDAY NIGHT AND MONDAY WITH
SHOWERS CONTINUING INTO TUESDAY. THE CURRENT GUIDANCE HAS THE
FRIDAY SYSTEM STRONGER THAN THOSE FOR THURSDAY AND SATURDAY WITH
THE STORM FOR LATE SUNDAY NIGHT AND MONDAY THE STRONGEST OF THE
FOUR. THAT COULD CHANGE WITH LATER GUIDANCE.

SOME VERY PRELIMINARY FORECAST RAINFALL TOTALS FOR THURSDAY
THROUGH TUESDAY OF NEXT WEEK...

COAST...........2 TO 3 INCHES.
VALLEYS.........3 TO 5 INCHES.
MOUNTAINS.......4 TO 8 INCHES.
UPPER DESERTS...1 TO 2 INCHES.
LOWER DESERTS...0.5 TO 1 INCH.

LOCAL AMOUNTS OF 12+ INCHES ARE POSSIBLE IN THE MOUNTAINS...
ESPECIALLY ON THE LOWER COASTAL SLOPES OF THE SAN BERNARDINO
COUNTY MOUNTAINS. FLOODING POTENTIAL COULD INCREASE MARKEDLY BY
MONDAY IF THESE STORMS DEVELOP AS CURRENTLY FORECAST.

SNOW LEVELS WILL LOWER TO AROUND 4000 FEET AT TIMES. SNOWFALL OF 4
FEET OR MORE IS POSSIBLE ON THE HIGHER PEAKS WITH 2 FEET OR MORE
ABOVE 6500 FEET.
