AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
218 PM PST MON DEC 6 2010

.SYNOPSIS...A FRONT WILL APPROACH DURING THE DAY TUESDAY. RESULTING
IN INCREASING WINDS DURING THE DAY AND HEAVY RAIN DEVELOPING AFTER
MIDNIGHT. RAINFALL AMOUNTS WILL BE LESS IN RAIN SHADOWED AREAS LIKE
HUMBOLDT BAY AND WEAVERVILLE.

&&

.DISCUSSION...
RELATIVELY FEW CHANGES NEEDED TODAY OTHER THAN TO BUMP UP POPS
TONIGHT FOR A PASSING S/W THAT COULD BRING A FEW HUNDREDTHS OF AN
INCH TO THE COAST NORTH OF THE CAPE...MAINLY NEAR CEC. FOR THE
REST OF THE WEEK...A COUPLE OF UPPER LEVEL WAVES WILL INTERACT
WITH A STALLED FRONT THAT WILL BE DRAPED OVER THE CWA RESULTING IN
AT LEAST TWO EPISODES OF WIDESPREAD RAINFALL. THE FIRST ROUND WILL
ARRIVE WED EVENING WITH THE INITIAL FRONTAL PASSAGE AND...WITH
TIMING MORE CERTAIN AT THIS POINT...WENT AHEAD AND REMOVED MENTION
OF PRECIP FOR MOST AREAS PRIOR TO 21Z/1PM TUES. THIS STILL SEEMS
PRETTY GENEROUS CONSIDERING MOST GUIDANCE HOLD THE FRONT OFF UNTIL
AFTER 00Z/4PM. AGREE WITH PREV SHIFT THAT PRECIP WILL BECOME MORE
SHOWERY LATE WED INTO THURS AHEAD OF THE NEXT UPPER WAVE WHICH
CURRENTLY LOOKS TO ARRIVE ON THURS AND WILL BRING ANOTHER ROUND OF
WIDESPREAD PRECIP. RIGHT NOW IT LOOKS LIKE AREAS SOUTH OF CAPE
MENDOCINO WILL SEE THE BRUNT OF THE SECOND EVENT. WHEN ALL IS SAID
AND DONE...48-HR RAINFALL TOTALS STILL LOOK LIKE A WIDESPREAD 1-2
INCHES WITH FAVORED AREAS SEEING 3+ INCHES OF RAIN AND SHADOWED
AREAS LIKE HUMBOLDT BAY AND WEV SEEING LESS THAN AN INCH. HAVE A
HUNCH THAT QPF WILL NEED TO BE INCREASED FOR THURS THOUGH. THE
OTHER BIG CONCERN HAS BEEN WIND WHICH LOOKS LESS IMPRESSIVE ALONG
THE COAST SO CONFIDENCE IN ACTUALLY MEETING WIND ADVISORY
CRITERIA...EXCEPT PERHAPS LOCALLY ALONG THE DEL NORTE COAST...IS LOW.

BEYOND THURS...TAPERED POPS OFF INTO THE WEEKEND...ESPECIALLY IN THE
SOUTH...AND TIGHTENED THE POP GRADIENT ACROSS OUR CWA WITH SOUTHERN
AREAS MORE LIKELY TO DRY OUT UNDER A BUILDING RIDGE. SOME
UNCERTAINTY STILL EXISTS IN OUR FAR NORTHERN AREAS...MAINLY JUST
DEL NORTE...SO HELD ONTO CHANCE POPS LONGER THERE. FINALLY...AM
HESITANT TO DECREASE POPS ON FRI AS THERE IS SOME HINT IN THE
GUIDANCE OF A THIRD WAVE COMING OUT OF THE PACIFIC AHEAD OF THE
BUILDING RIDGE WHICH COULD POTENTIALLY RESULT IN A THIRD ROUND OF
PRECIP...THOUGH PROBABLY MUCH MORE MINOR. MODELS USUALLY STRUGGLE
TO CAPTURE AND ACCURATELY REPRESENT INDIVIDUAL WAVES WHEN THE FLOW
OPENS UP OVER THE PAC LIKE THIS SO LEFT FRI UNCHANGED FOR NOW. CLARK

&&

.AVIATION...A FEW LIGHT SHOWERS ASSOCIATED WITH A WEAK DISTURBANCE
WILL BRING OCCASIONAL MFVR CONDITIONS TO THE NORTH COAST THIS
EVENING. OTHERWISE VFR CONDITIONS ARE EXPECTED TONIGHT WITH
SOUTHEAST OFFSHORE FLOW. TOMORROW WINDS WILL INCREASE THROUGH THE
DAY AS A FRONTAL BOUNDARY APPROACHES...HOWEVER CONDITIONS ARE
EXPECTED TO REMAIN VFR. MKK

&&

.MARINE...A FRONTAL BOUNDARY WILL APPROACH THE OUTER WATERS THIS
AFTERNOON AND SLOWLY MOVE ONSHORE TUESDAY OFFSHORE. THIS WILL BRING
GALE CONDITIONS TO THE OUTER WATERS TONIGHT. THESE WILL SPREAD SOUTH
LATE TONIGHT. MODELS AND MOS HAVE BACKED OFF A LITTLE FOR THE INNER
WATERS...BUT GALE WARNING STILL SEEMS REASONABLE IN THE NORTH.
SOUTHERN INNER WATERS APPEAR TO BE CLOSE TO GALE CONDITIONS TUESDAY
AFTERNOON THROUGH TUESDAY NIGHT...BUT AT THIS POINT ONLY EXPECT
OCCASIONAL GUSTS TO 35KTS. THIS WILL NEED TO BE MONITORED AS IT GETS
CLOSER. GALE CONDITIONS WILL CONTINUE THROUGH MID WEEK IN THE OUTER
WATERS. TUESDAY NIGHT INTO WEDNESDAY SEAS WILL BE IN A VERY CONFUSED
STATE WITH STRONG SOUTHERLY WIND WAVE COMBINED WITH LONGER PERIOD
NORTHWESTERLY SWELL. WINDS WILL DIMINISH BY THU BUT HIGH AMPLITUDE
SWELL WILL REMAIN INTO LATE WEEK. MKK.
