AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1025 AM PST SAT DEC 29 2012

.DISCUSSION...AS OF 9:00 AM PST SATURDAY...AN UPPER LOW OFF THE
CENTRAL CALIFORNIA COAST CONTINUES TO MOVE SLOWLY SOUTHWARD TOWARD
SOUTHERN CALIFORNIA. THIS LOW BROUGHT SHOWERS TO MAINLY THE SAN
FRANSISCO BAY SOUTHWARD...WITH THE HIGHEST ACCUMULATIONS IN
MONTEREY AND SANTA CRUZ COUNTIES. OVER THE PAST SIX HOURS...BIG
SUR RECEIVED A HALF AN INCH OF RAIN.

THE FORECAST WAS UPDATED THIS MORNING TO DROP SNOW LEVELS ACROSS
THE REGION. TEMPERATURES THIS MORNING HOVERED AROUND THE FREEZING
MARK AT AN ELEVATION OF 2200 FEET. LIGHT SNOW ACCUMULATION WILL BE
POSSIBLE DOWN TO 2500 FEET...WITH A RAIN/SNOW MIX POSSIBLE ALL THE
WAY DOWN TO 2000 FEET. A FEW OF THE HIGHEST
ELEVATIONS...ESPECIALLY IN MONTEREY AND SAN BENITO COUNTIES COULD
EASILY SEE BETWEEN 2 AND 5 INCHES OF SNOW THROUGH THIS EVENING.

SHORT TERM MODELS INDICATE THAT RAIN/SNOW SHOWERS WILL CONTINUE
OVER THE SOUTHERN THIRD OF THE REGION THROUGH THE AFTERNOON INTO
THE EVENING HOURS. TONIGHT THESE SHOWERS WILL END WITH DRY WEATHER
PRESENT THROUGH AT LEAST MONDAY MORNING. IN
ADDITION...TEMPERATURES OVERNIGHT ARE FORECAST TO FALL AT OR BELOW
THE FREEZING MARK THROUGH MANY OF THE INLAND LOCATIONS...WITH
LIGHT WINDS AND MOSTLY CLEAR SKIES. IN FACT...A FEW LOCATIONS IN
THE NORTH BAY...AS WELL AS SOUTHERN SAN BENITO COUNTIES WILL FALL
INTO THE MID 20S.

.PREVIOUS DISCUSSION...AS OF 3:30 AM PST SATURDAY...A RAINY START TO THE
WEEKEND THIS MORNING. A COLD UPPER LOW IS CENTERED DUE WEST OF
PIGEON POINT AT THIS HOUR. THE ASSOCIATED FRONTAL RAIN BAND IS
PUSHING NORTHEAST WHILE THE LOW PINWHEELS SSE PARALLELING THE
COAST. RAIN HAS ALREADY TAPERED OFF IN THE NORTH BAY WHILE
PRECIPITATION CONTINUES FROM THE GOLDEN GATE SOUTH. HIGHEST RAIN
RATES HAVE BEEN OBSERVED IN THE SOUTHERN HALF OF THE AREA WITH
ALMOST HALF AN INCH AT BEN LOMAND IN THE SANTA CRUZ MOUNTAINS AS
WELL AS AT SEA LEVEL IN MONTEREY. URBAN LOCATIONS IN THE SF BAY
AREA HAVE RECEIVED UP TO A QUARTER OF AN INCH.

SNOW LEVELS ARE AROUND 3500 FEET THOUGH RAIN SNOW MIX COULD OCCUR
AS LOW AS 2500 FEET. UP TO 2 TO 3 INCHES TOTAL SNOWFALL LIKELY ABOVE
3000 FEET...AND AS MUCH AS 4 INCHES AT HIGHER ELEVATIONS IN THE
SANTA LUCIA MOUNTAINS. SLIPPERY ROADS SHOULD BE EXPECTED ABOVE
2500 FEET.

AREAS OF PRECIP WILL CONTINUE TO MOVE SOUTH TODAY...ENDING ACROSS
THE SF BAY AREA BY MID MORNING AND MRY BAY BY NOON. SOME SHOWERS
WILL STILL BE POSSIBLE IN SOUTHERN MONTEREY COUNTY INTO AFTERNOON.

THE REST OF THE WEEKEND WILL STAY COOL WITH HIGHS ONLY REACHING
INTO THE LOW TO MID 50S. AS CLOUDS CLEAR TONIGHT TEMPERATURES
COULD PLUMMET TONIGHT WITH PATCHY FROST IN NORTH AND EAST BAY
VALLEYS OVERNIGHT. SUNDAY NIGHT WILL BE A DEGREE OR TWO COOLER AS
WINDS REMAIN LIGHT.

THE UPCOMING WEEK AND NEW YEAR LOOK TO START OUT QUIETLY. A CUT
OFF LOW BRUSHES BY THE AREA MONDAY NIGHT INTO TUESDAY...HOWEVER 00Z
MODEL RUNS KEEP NEARLY ALL PRECIP OFFSHORE. ANOTHER SYSTEM LATE
WEDNESDAY MAY PRODUCE LIGHT RAIN ACROSS THE CWA. MODELS REMAIN
UNCERTAIN WITH THE ECMWF OFFERING AN INTERESTING SOLUTION THAT
