AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
1013 AM PDT FRI OCT 19 2012

.UPDATE...
QUICK UPDATE FOR LATEST SATELLITE AND SHORT-TERM MODEL TRENDS.
GIVEN THE SHIELD OF THICK STRATUS ALONG THE MENDO COAST WENT
CLOUDY FOR THE REST OF THE DAY THERE ALTHOUGH SOME LOCALIZED SPOTS
WILL SEE OCCASIONAL SUNSHINE. NORTH OF THE CAPE EXPECT THE STRATUS
TO MAKE PROGRESS THROUGH THE DAY TODAY ALONG WITH THE HIGH/MID
LEVEL DECK COMING IN OVERHEAD. BROOKINGS SHOWING OVERCAST AT 4400
FEET SO CRESCENT CITY SHOULD CLOUD UP PRETTY SOON. BETWEEN THERE
AND CAPE MENDOCINO EXPECT A DECENT AMOUNT OF SUNSHINE THROUGH
EARLY TO MID AFTERNOON BEFORE THE OVERCAST SETTLES IN. QUICK SHOT
OF LIGHT TO OCNL MODERATE RAIN PROBABLY ONLY LASTING A FEW HOURS
WITH THE COLD FRONT THIS EVENING...AMOUNTS STILL LOOK TO BE OF THE
TRACE TO A TENTH OF AN INCH VARIETY WITH LITTLE TO NOTHING SOUTH
OF CAPE MENDOCINO AND INLAND FROM THE NORTH COAST. THE EXCEPTION
WILL BE SOME OF THE INTERIOR MOUNTAINS OF HUMBOLDT DEL NORTE AND
NRN TRINITY WHERE SOME WETTING RAINS MAY OCCUR. BULK OF THE
RAINFALL WILL BE DONE BY MORNING WITH PRETTY DECENT DAY SATURDAY
OUTSIDE OF SOME LINGERING SHOWERS/MIST AND CLOUDS IN THE NORTHERN
INTERIOR. AAD

&&

.AVIATION...LOW CIGS ARE PRESENTLY BEGINNING TO ERODE AROUND KUKI
PER VIS SAT PIX. TAF APPEARS TO BE ON TRACK. 3SM VSBY AT KACV IS
EXPECTED TO BE BRIEF...BUT MORE FOG AND LOW CLOUDS ARE EXPECTED TO
RETURN LATER IN THE DAY AS FOG BANK HAS ROUNDED CAPE MENDO FROM THE
S AND IS EXPECTED TO ADVECT INLAND AS GRADIENT WIND FLOW VEERS TO
MORE W ALONG WITH DIURNAL SEABREEZE. APPEARS LOWEST CIGS MAY NOT
MAKE IT UP THE COAST TO KCEC...BUT CIGS THERE WILL BE LOWERING THIS
AFTERNOON AHEAD OF THE APPROACHING FRONT AND PRECIP. /SEC

.PREV DISCUSSION... /ISSUED 330 AM PDT FRI OCT 19 2012/

SYNOPSIS...TEMPERATURES WILL COOL TODAY AS CLOUDS INCREASE ACROSS
THE REGION AHEAD OF AN APPROACHING STORM. LIGHT RAIN IS EXPECTED NORTH
OF CAPE MENDOCINO OVERNIGHT WITH SOME SUNSHINE RETURNING FOR THE
WEEKEND WHILE TEMPERATURES REMAIN COOL. ANOTHER STORM WILL BRING
MORE RAIN ALONG WITH THE POTENTIAL FOR HIGH ELEVATION SNOW HEADING
INTO NEXT WEEK.

DISCUSSION...SAT IMAGERY SHOWS MID AND HIGH CLOUDS MOVG INTO NRN
PORTIONS OF CWA THIS MORNING WITH STRATUS PUSHING N ALONG THE
MENDO COAST AND INTO SRN MENDO INTERIOR VALLEYS. MODELS HANDLING
THIS INCREASED SLY GRADIENT POORLY WITH EARLIEST HINT OF STRATUS
DEPICTED OVER THE WATERS BY THIS AFTERNOON. EXPECT LOW CLOUDS TO
SCT OVER UKI VALLEY BY LATE THIS MORNING WITH STRATUS IMPACTING
THE MENDO COAST THROUGH THE DAY AS SLY WINDS SHIFT TO ONSHORE THIS
AFTERNOON. A WEAKENING FRONT WILL MOVE INTO CWA THIS EVENING AND
PUSH INLAND OVERNIGHT. A FEW SPRINKLES ARE POSSIBLE NEAR THE ORCA
BORDER LATE THIS AFTERNOON...BUT BULK OF -RA EXPECTED IN THE
EVENING AND OVERNIGHT. QPF TOTALS REMAIN LOW...FROM A TRACE TO
AROUND 0.25 INCHES IN FAVORED AREAS OF DEL NORTE COUNTY. A FEW
SHOWERS AND STRATO CU WILL LINGER INTO SAT MORNING BEFORE DRIER
AIR MOVES IN SAT AFTERNOON RESULTING IN CLEARING SKIES. MUCH OF
MENDOCINO COUNTY MAY STAY JUST PARTLY CLOUDY UNTIL SUNDAY WHEN THE
NEXT FRONT APPROACHES. MODELS REMAIN IN GOOD AGREEMENT IN A DEEP
COLD TROUGH DEEPENING OVER THE PAC NW BEGINNING SUN. SNOW LEVELS
WILL FALL TO 4500-5500 FT SAT NIGHT/SUN MORNING WITH PRECIP CHCS
INCREASING SUN AFTERNOON/EVENING. LGT SNOW ACCUMULATIONS EXPECTED
OVER HIGHER TERRAIN OF THE SISKIYOU AND TRINITY ALPS RANGES...BUT
NO ACCUMULATIONS EXPECTED AS PASS LEVELS. AS THE UPPER LOW
APPROACHES...HEIGHTS WILL FALL SHARPLY WITH CONVECTIVE SHOWERS AND
AN ISOLD TSTM...ALONG WITH THE POTENTIAL FOR SMALL HAIL. TIMING
AND INTENSITY OF THE STORM REMAIN DIFFICULT TO PINPOINT UNTIL WE
GET CLOSER BUT WILL KEEP THE SAME GENERAL MESSAGE IN THE HWO AND
WEATHER STORY. SHORTWAVES ROTATING AROUND THE UPPER LOW WILL
MAINTAIN PERIODS OF PRECIP ACROSS THE REGION THROUGH THE MIDDLE OF
NEXT WEEK AS THE LOW REMAINS OFF THE COAST. KEPT HIGH LIKELY TO
CAT POPS ACROSS THE NORTHERN HALF OF THE CWA DESPITE THE RANGE
GIVEN THE PATTERN...BUT IT IS LIKELY THERE WILL BE SOME PERIODS OF
DRY WEATHER...PERHAPS NOT LASTING 12 HOURS...IN BETWEEN
SHORTWAVES. WHILE RAINFALL OVER THE COURSE OF SEVERAL DAYS COULD
VERY WELL BE ON THE ORDER OF A FEW INCHES DO NOT EXPECT A
PARTICULARLY HEAVY RAIN EVENT IN ANY ONE PERIOD. BETTER MOISTURE
FEED APPEARS TO SET UP FURTHER NORTH OF OUR AREA WITH FCST PWATS
OF 1.5-1.75 INCHES. MODELS DIVERGE BEYOND THE MIDDLE OF NEXT WEEK
BUT A FAIRLY PROGRESSIVE PATTERN IS EXPECTED...SO KEPT POPS ABOVE
CLIMO THROUGH THE EXTENDED.

MARINE...APPROACHING FRONT HAS BEEN BUSTING UP THE NORTHERLY
PRESSURE GRADIENT. WINDS WILL SHIFT AROUND TO THE NORTHWEST
AND THEN TO THE NORTH AND INCREASE LATE TONIGHT. WINDS WILL BE
IN THE SMALL CRAFT ADVISORY RANGE OF 20-25 KT SOUTH OF THE CAPE ON
SAT...WITH SEAS RAMPING UP TO 10 FT BY AFTERNOON. NORTH OF THE
CAPE...IT WILL BE TRICKY AS WINDS FLIRT WITH GUSTS TO 25 KT. NORTH
WINDS SHOULD TREND DOWNWARD ON SUN...EXCEPT IN THE FAR SW PORTION OF
THE PZZ455 AND AROUND PT ARENA WHERE LOCAL ACCELERATIONS MAY KEEP IT
BREEZY. BY MONDAY...SOUTH AND SOUTHWEST WINDS WILL PREVAIL
THROUGHOUT AS LOW PRESSURE SAGS SOUTHWARD FROM OFFSHORE OREGON
WATERS. RIGHT NOW WINDS DO NOT LOOK TO BE VERY STRONG WITH THIS LOW
AND WILL STAY WITH THE CURRENT FORECAST AND MODEL GUIDANCE. HESITANT
TO HOIST SMALL CRAFT ADVISORIES FOR SAT AS IT IS JUST OUTSIDE THE
WINDOW. THUS THE DAY SHIFT WILL HAVE TO ISSUE THE ADVISORIES FOR
WINDS AND SEAS SOUTH OF THE CAPE.
