more details on potential stormy weather

This update gives more specific info regarding rainfall amounts for the valley and foothills. From the National Weather Service in Sacramento:

STORMY WEATHER HEADED FOR NORTHERN CALIFORNIA THIS WEEKEND AND
INTO NEXT WEEK...

A LARGE WEATHER SYSTEM DROPPING OUT OF THE GULF OF ALASKA WILL
BRING RAIN...WIND AND LARGE AMOUNTS OF MOUNTAIN SNOW TO NORTHERN
CALIFORNIA BEGINNING FRIDAY...AND LASTING THROUGH THE WEEKEND AND
INTO NEXT WEEK.

PERIODS OF HEAVY RAIN AND MOUNTAIN SNOW SHOULD BEGIN FRIDAY NIGHT
AND SATURDAY. NEARLY CONTINUOUS RAIN AND SNOW IS EXPECTED THROUGH
THE WEEKEND...WITH MORE PERIODS OF HEAVY PRECIPITATION EXPECTED
EARLY NEXT WEEK.

THE CENTRAL VALLEY COULD SEE 2 TO 5 INCHES OF RAINFALL FROM FRIDAY
INTO EARLY NEXT WEEK...WITH RAINFALL AMOUNTS EXCEEDING 6 INCHES IN
THE FOOTHILLS. AT THE HIGHER ELEVATIONS...NEW SNOWFALL ACCUMULATIONS
OF SEVERAL FEET ARE POSSIBLE. SNOW LEVELS ARE EXPECTED TO BE
FAIRLY TYPICAL FOR THIS TIME OF YEAR VARYING BETWEEN 4000 AND 6000
FEET. THIS PUTS SNOW LEVELS BELOW THE MAJOR PASS LEVELS AND TRAVEL
DIFFICULTIES THROUGH THE MOUNTAINS WILL ALMOST CERTAINLY BECOME A
FACTOR AS HEAVY SNOW ACCUMULATIONS OCCUR. GUSTY WINDS WILL BRING
BLOWING SNOW AND REDUCED VISIBILITIES AS WELL.

AT THE LOWER ELEVATIONS...LEAF FALL AND CLOGGED STORM DRAINS STILL
REMAIN A PROBLEM THIS SEASON AND WILL LIKELY CAUSE LOCALIZED
STREET FLOODING DURING PERIODS OF HEAVY RAIN.

THE WET PATTERN MAY CONTINUE THROUGH MUCH OF NEXT WEEK.

NORTHERN CALIFORNIANS SHOULD BE PREPARED FOR AN EXTENDED PERIOD OF
VERY WET WEATHER BEGINNING THIS FRIDAY. IF TRAVELING...ESPECIALLY
THROUGH THE MOUNTAINS...BE SURE AND CHECK THE LATEST WEATHER
AND ROAD CONDITIONS BEFORE DEPARTURE AND CONTINUE TO MONITOR THIS
DEVELOPING STORM SYSTEM.
