AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
827 AM PST SUN DEC 16 2012

.SYNOPSIS...A WARM FRONT MOVING INTO NW CALIFORNIA WILL CAUSE
RISING SNOW LEVELS TODAY AND BRING WIDESPREAD RAIN. WINDS WILL
ALSO INCREASE ALONG THE NORTH COAST THIS AFTERNOON AS LOW
PRESSURE MOVES INTO THE PACIFIC NORTHWEST. A TRAILING COLD FRONT
WILL CROSS THE REGION ON MONDAY...USHERING IN VERY COLD AIR BY
TUESDAY.

.UPDATE...DID AN UPDATE THIS MORNING TO ISSUE A WINTER WEATHER
ADVISORY FOR THE WEAVERVILLE AREA THIS MORNING. PRECIPITATION
APPEARS TO BE LINGERING LONGER THAN PREVIOUSLY EXPECTED. WEBCAMS
AND SHOW SNOW FALLING ON THE HWY 299 SUMMITS IN TRINITY COUNTY AND
SURFACE OBSERVATIONS SHOW TEMPERATURES RIGHT AT FREEZING IN
WEAVERVILLE. EXPECT 2 TO 4 INCHES OF SNOW WILL FALL TODAY AS A
WARM FRONT CROSSES THE AREA. FOR NOW HAVE SNOW LEVELS RISING
TONIGHT AS THE COLD FRONT APPROACHES THE AREA AND WINDS INCREASE
MIXING THE WARMER AIR INTO THERE. THERE IS A CHANCE THE PRECIP
WILL STAY ALL SNOW TONIGHT IN WEAVERVILLE AND THEY COULD RECEIVE
SIGNIFICANT ACCUMULATIONS TONIGHT AND MONDAY. THIS WILL NEED TO BE
MONITORED CLOSELY. MKK

.PREV DISCUSSION... /ISSUED 454 AM PST SUN DEC 16 2012/

SHORT TERM...A LARGE UPPER HIGH SITUATED NEAR 32N143W IS ROTATING
A RIDGE AXIS TOWARD NW CALIFORNIA THIS MORNING AS SEEN IN WV
SATELLITE. THIS IN CONJUNCTION WITH A DEPARTING SHORTWAVE HAS MADE
FOR A CHALLENGING FORECAST THIS MORNING. DESPITE MORNING RADAR
INDICATING BROAD AREA OF PRECIPITATION, THE RIDGE SHOULD PUT AN
END TO PRECIPITATION FOR MOST AREAS EARLY THIS MORNING. DEL NORTE
AND NORTHERN HUMBOLDT AND TRINITY COUNTIES COULD SEE SOME
PRECIPITATION EARLY THIS MORNING, BUT SHOULD CLEAR OUT BY MID
MORNING. THIS WILL ALLOW FOR A FEW HOURS OF DRY WEATHER THIS
MORNING. IF THE RIDGE REMAINS TOO DIRTY, WILL NEED TO UPDATE THE
FORECAST TO BRING RAIN BACK IN.

THIS AREA OF PRECIPITATION IS ASSOCIATED WITH A WARM FRONT SLIDING
INTO THE REGION. THIS WARM FRONT IS BRINGING WARM AIR BACK AND
CAUSING THE SNOW LEVELS TO RISE THIS MORNING. SNOW LEVELS ARE
ALREADY PUSHING 3000 FEET THIS MORNING AND WILL CONTINUE TO RISE
THROUGH THE DAY. THE LONE HOLD OUT IS EASTERN TRINITY COUNTY WHERE
SNOW LEVELS ARE STILL AROUND 2000 FEET. SNOW LEVELS ARE EXPECTED
TO BE AROUND 5000 TO 7000 FT BY THIS AFTERNOON. AS SUCH, SNOW WILL
BE LIMITED THIS MORNING DUE TO RISING SNOW LEVELS AND LIMITED
PRECIPITATION. EVEN SO, ANOTHER 1 TO 3 INCHES ARE POSSIBLE ACROSS
THE HIGHER MOUNTAINS IN DEL NORTE AND EASTERN HUMBOLDT COUNTIES
AND ACROSS THE HIGHER PASSES IN TRINITY COUNTY. WITH LIMITED
AMOUNTS EXPECTED, OPTED NOT TO ISSUE ANY WINTER WEATHER PRODUCTS.

THE WARM FRONT'S ASSOCIATED LOW WILL SLIDE INTO THE PACIFIC
NORTHWEST TODAY WITH THE TRIPLE POINT CROSSING SOUTHERN OREGON.
THIS WILL CAUSE A TIGHTENING OF THE PRESSURE GRADIENT ACROSS FAR
NORTHERN CALIFORNIA, AS WELL AS CAUSE A SQUEEZE PLAY BETWEEN THE
SISKIYOUS AND THE FRONTAL BOUNDARY. COMBINED, THIS WILL YIELD
STRONG GUSTY WINDS ALONG THE DEL NORTE AND NORTHERN HUMBOLDT COAST
THIS AFTERNOON AND EVENING. DID NOT ALTER ANYTHING WITH THE
ONGOING WIND ADVISORY AS IT STILL LOOKS TO BE ON TRACK.

AFTER LOW PRESSURE SLIDES INTO THE PAC NW AND THE WARM FRONT WORKS
ITS WAY INTO CENTRAL CALIFORNIA, THE TRAILING COLD FRONT WILL DROP
ACROSS THE REGION. MODELS HAVE BEEN CONSISTENT OVER THE LAST
SEVERAL NIGHTS WITH 1000-500 MB THICKNESSES FALLING TO AROUND
522DAM BY EARLY TUESDAY MORNING. TEMPERATURE GUIDANCE CONTINUES TO
SHOW A WARM BIAS UNDER THIS PATTERN, SO HAVE DROPPED THE MIN TEMP
FOR TUE MORNING BY ABOUT 5 TO 10 DEGREES BELOW MODEL GUIDANCE.
WITH THIS DROP, MOST AREAS WILL EXPERIENCE FREEZING TEMPS TUE
MORNING, WITH THE EXCEPTION OF THE MENDOCINO COAST. WILL NEED TO
LOOK AT FREEZE WARNING FOR THE REDWOOD COAST DURING THIS TIME.

TUESDAY WILL BEGIN A SHORT DRY SPELL AS A RIDGE CROSSES THE AREA.
THIS WILL ALSO ALLOW FOR MODEST WARMING AFTER THE COOL DOWN. MODELS
AGREE THIS DRYING WILL BE SHORT LIVED AS THE RIDGE SHIFTS OFF TO
THE EAST ON WEDNESDAY. RAIN AND SNOW WILL RETURN ON WEDNESDAY. BFG

LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY. MODELS SHOW A LONG
WAVE TROUGH DEVELOPING OVER THE WEST COAST MIDWEEK AND REMAINING
IN PLACE THROUGH THE END OF THE WEEK. KEPT POPS WELL ABOVE CLIMO
DURING THIS TIME PERIOD. COLD AIR WITH THIS TROUGH WILL ALLOW SNOW
LEVELS AND TEMPERATURES TO DROP SIGNIFICANTLY. THE QUESTION IS
MOISTURE. IF ANY STORMS SET UP WITH GOOD MOISTURE THERE IS THE
POTENTIAL FOR DECENT SNOWFALL AT LOWER ELEVATIONS ALONG WITH
EMBEDDED CONVECTION. THIS CONTINUES TO BE WATCHED CLOSELY. MS

AVIATION...NORTH COAST AIRPORTS HAVE RISEN TO VFR CIGS/VIS THIS
MORNING WITH MOSTLY -RA CONTINUING. HOWEVER...LOTS OF LOW RAGGED
CLOUDS PRESENT SO MAY SEE THE OCCASIONAL MVFR CLOUDS. AFTERNOON
WILL RETURN PREDOMINANT CIGS/VIS TO MVFR AS RAIN CONTINUES. GUSTY
WINDS WILL ALSO CAUSE ISSUES AT CEC THIS AFTERNOON AND EVENING.
UKI REMAIN UNDER A LOW OVERCAST THIS MORNING WITH IFR-MVFR VIS.
TA

MARINE...NEARSHORE BUOYS THIS MORNING SHOW SOUTHERLY WINDS
GRADUALLY INCREASING. THE SOUTHERLY WINDS WILL INCREASE INTO
THIS AFTERNOON AS A FRONT APPROACHES OUR WATERS. GALE CONDITIONS
ARE EXPECTED NORTH OF CAPE MENDOCINO THIS AFTERNOON AND EVENING AS
THE FRONT CROSSES THE WATERS. LEFT THE GALE WARNINGS UNCHANGED,
BUT EXTENDED THE SCA FOR ZONE 455 BECAUSE WINDS HAVE BEEN GUSTY
NEAR BUOY 14 AND DON'T EXPECT THEM TO DROP MUCH MORE THIS MORNING.
THE OTHER SCA'S REMAIN UNCHANGED. THE GUSTY SOUTH WINDS WILL
GENERATE SHORT PERIOD SOUTHERLY WAVES INTO TONIGHT MIXED WITH
LONGER PERIOD WESTERLY WAVES. WINDS WILL EASE AND TURN TO THE WEST
LATE TONIGHT AS THE FRONT MOVES INLAND AND SOUTHERLY SEAS WILL
LOWER. HOWEVER, LONG PERIOD WESTERLY WAVES ASSOCIATED WITH THIS
FRONT WILL BUILD TONIGHT AND PEAK EARLY MONDAY MORNING. MODELS
SHOW THESE WAVES PEAKING NEAR 20 FT, SO ISSUED A HAZ SEAS WATCH
FOR ALL OF THE WATERS FOR LATE TONIGHT INTO MONDAY MORNING. THE
HIGHEST WAVES LOOK TO BE NORTH OF CAPE MENDOCINO AND ACROSS THE
OUTER WATERS. THESE WAVES WILL ALSO PRODUCE BREAKERS AROUND 20 FT.
BUT THESE AREN'T BIG ENOUGH FOR A HIGH SURF ADVISORY AND DOUBT
MANY PEOPLE WILL BE AT THE BEACHES LATE TONIGHT INTO MONDAY
MORNING IN THE RAIN, WHEN THE BIGGEST BREAKERS WILL BE HITTING.
BUT WE STILL ARE WAITING FOR THESE WAVES TO PASS SOME BUOYS LATER
TODAY TO KNOW JUST HOW BIG THEY REALLY WILL BE. THE STORMY PATTERN
LOOKS TO CONTINUE THIS WEEK WITH WESTERLY WAVES DOMINATING THE
WATERS. MS
