AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
438 AM PST SAT DEC 18 2010

.SYNOPSIS...A FRONT MOVING THROUGH THE AREA TODAY WILL CONTINUE TO
BRING RAIN AND SNOW SHOWERS ACROSS THE REGION. THUNDERSTORMS ARE
POSSIBLE THROUGH THE DAY...MAINLY NORTH IN HUMBOLDT AND DEL NORTE
COUNTIES.

&&

.DISCUSSION...AN UNSTABLE AIRMASS IS MOVING INTO NW CALIFORNIA THIS
MORNING AS A FRONT SLIDES OFF THE SE. SHOWERS AND THUNDERSTORMS ARE
ACCOMPANYING THIS AIRMASS NORTH OF CAPE MENDOCINO, BUT WILL SLIDE TO
THE SOUTH FOLLOWING THE FRONT. THUNDERSTORMS HAVE BEEN EXPANDED IN
THE FORECAST TO ACCOUNT FOR ACTIVITY OCCURRING FURTHER INLAND.
OTHERWISE, NO SIGNIFICANT CHANGES HAVE BEEN MADE TO THE ONGOING
FORECAST. A WINTER WEATHER ADVISORY HAS BEEN ISSUED FOR MOUNTAIN SNOW
ABOVE 3000 FEET THROUGH SUNDAY NIGHT. SNOW LEVELS HAVE BEEN ON A
STEADY RISE THIS MORNING AND ARE CURRENTLY PUSHING 4500 TO 5000
FEET. SNOW LEVELS WILL REMAIN HIGH TODAY, BUT WILL STEADILY FALL AS
A COLD FRONT SWEEPS QUICKLY ACROSS THE AREA ON SUNDAY. TODAY'S
SHOWERS WILL PRODUCE SEVERAL INCHES OF SNOW IN THE HIGHER
ELEVATIONS. HOWEVER, WITH SHOWERS CONTINUING THROUGH THE WEEKEND AND
SNOW LEVELS BEGINNING TO FALL TONIGHT, SNOW ACCUMULATIONS WILL BEGIN
TO AFFECT THE LOWER ELEVATIONS.
MODELS INDICATE THE COLD FRONT MOVING THROUGH THE AREA ON SUNDAY TO
BE NEGATIVELY TILTED. IF ENDS UP BEING A STRONG NEGATIVE TILT, THERE
COULD BE A SIGNIFICANT THREAT OF THUNDERSTORMS. THE CURRENT FORECAST
ONLY INDICATES A SLIGHT CHANCE OF THUNDERSTORMS, BUT THIS MAY NEED
TO BE CHANGED TO SHOW SCATTERED THUNDERSTORMS.
AFTER SUNDAY, RAIN WILL TAPER TO SHOWERS AND REMAIN AS SUCH THROUGH
THE FIRST HALF OF THE WEEK. THE LARGE UPPER LOW DROPPING SOUTH OUT
OF THE GULF OF ALASKA WILL PUSH THE JET FAR ENOUGH SOUTH TO LEAVE NW
CALIFORNIA OUT OF THE BULK OF PRECIPITATION FOR THE EARLY HALF OF
THE WEEK, SHOVING DOWN INTO CENTRAL AND SOUTHERN CALIFORNIA ONCE
AGAIN. WHILE MODEL AGREEMENT IS NOT GOOD BEYOND WED, IF YOU BLUR
YOUR EYES, EARLY INDICATIONS ARE A RELATIVELY DRY LATE HALF OF THE
WEEK WITH ANOTHER FRONT FOR NEXT WEEKEND.

OVERALL...THE MAIN THREAT FOR THE NEXT 2 DAYS WILL BE THUNDERSTORMS
AND MOUNTAIN SNOW. BFG

&&

.AVIATION...SHOWERS AND ISOLATED THUNDERSTORMS WILL BRING PERIODS OF
MVFR CONDITIONS THIS MORNING. THESE STORMS WILL PRODUCE
LIGHTNING...GUSTY WINDS...HEAVY RAIN...AND POSSIBLY HAIL...AND
MAINLY IMPACT COASTAL AREAS. RAIN AND HIGH ELEVATION SNOW SHOWERS
WILL CONTINUE TODAY AND BECOME MORE STRATIFORM IN THE LATE
AFTERNOON. TH

&&

.MARINE...SOUTH WINDS HAVE EASED IN THE WAKE OF A FRONT...BUT WILL
REMAIN MODERATE TO STRONG THROUGH MOST OF NEXT WEEK. WINDS WILL
INCREASE AGAIN SUNDAY AFTERNOON WITH GALES POSSIBLE ACROSS THE OUTER
WATERS THROUGH SUNDAY NIGHT. HAVE THEREFORE HOISTED A GALE WATCH.
MODELS CAME WAY DOWN ON FORECAST SWELL HEIGHTS FOR THE WEST SWELL
EXPECTED SUNDAY. THINK CURRENT MODEL SWELL FORECAST IS MORE
REASONABLE GIVEN FORECAST WINDS AND FETCH...WITH THE WEST SWELL
PEAKING AROUND 15 FEET SUNDAY NIGHT. TH

&&

FOR THE CAZ003-004.
