AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
422 AM PST THU FEB 11 2016

.SYNOPSIS...SEVERAL WEAK FRONTAL SYSTEMS WILL BRING OCCASIONAL
LIGHT RAIN TO THE AREA THROUGH SUNDAY. MONDAY AND TUESDAY HIGH
PRESSURE RETURNS BEFORE ANOTHER SYSTEM LOOKS TO BRING RAIN AND
HIGH ELEVATION SNOW MID TO LATE WEEK.

&&

.DISCUSSION...THE RIDGE OF HIGH PRESSURE HAS SHIFTED SLIGHTLY OFF
TO THE EAST THIS MORNING. A SHORTWAVE MOVING UP THE RIDGE IS
BRINGING ISOLATED SHOWERS TO DEL NORTE COUNTY THIS MORNING. THESE
VERY LIGHT SHOWERS WILL CONTINUE TODAY NORTH OF CAPE
MENDOCINO...ALTHOUGH MOST LOCATIONS WILL NOT SEE ANY SIGNIFICANT
RAINFALL AMOUNTS. ANOTHER WAVE WILL BRING ADDITIONAL CLOUDS AND A
CHANCE FOR LIGHT RAIN IN THE NORTH ON FRIDAY. THIS RAIN LOOKS TO
BE LIMITED TO HUMBOLDT AND DEL NORTE COUNTIES AND LESS THAN A
TENTH OF AN INCH. TEMPERATURES WILL GENERALLY BE ABOVE SEASONAL
NORMALS.

SATURDAY WILL BE A MAINLY DRY DAY WITH SOME SUNSHINE AROUND.
CLOUDS WILL INCREASE IN THE AFTERNOON AS THE NEXT SYSTEM
APPROACHES. SATURDAY NIGHT INTO SUNDAY A SHORTWAVE MOVING OVER
THE TOP OF THE RIDGE LOOKS BRING SOME RAIN...HOWEVER AGAIN IT
LOOKS LIKE AMOUNTS WILL BE LESS THAN A TENTH OF AN INCH IN MOST
PLACES.

THE RIDGE OF HIGH PRESSURE BUILDS BACK INTO THE AREA FOR MONDAY
AND TUESDAY. OFFSHORE FLOW AND THE RIDGE WILL BRING PLENTY OF
SUNSHINE TO NORTHWEST CA. TEMPERATURES WILL CONTINUE TO BE ABOVE
SEASONAL NORMALS.

WEDNESDAY AND THURSDAY MODELS ARE IN DECENT AGREEMENT THAT A
STRONG FRONTAL BOUNDARY WILL BRING A DECENT CHANCE FOR RAIN. THE
TROUGH BEHIND THE FRONT LOOKS TO BRING LOWER SNOW LEVELS. ALTHOUGH
THE MODELS ARE IN RELATIVELY GOOD AGREEMENT ON WIDESPREAD
PRECIPITATION KEPT POPS IN THE CHANCE TO LIKELY CATEGORY. IN THE
PAST WEEK SYSTEMS HAVE WEAKENED DRAMATICALLY WHEN WE GET CLOSER TO
THEM SO WILL WAIT ANOTHER RUN OR TWO TO RAISE POPS MORE
SIGNIFICANTLY. MKK

&&

.AVIATION...A WEAK FRONTAL BOUNDARY WILL BRING SOME LIGHT RAIN
SHOWERS TO COASTAL AIRFIELDS NORTH OF CAPE MENDOCINO EARLY THIS
MORNING. SHOWERS WILL DIMINISH BEHIND THE FRONT LATER THIS MORNING
AND ANY CEILINGS ASSOCIATED WITH THE SHOWERS WILL LIFT. THEN VFR
SHOULD PREVAIL FOR THE REST OF THE DAY AND EVENING WITH MID TO
UPPER CLOUD COVER EXPECTED OVER NORTHERN CALIFORNIA. SOME LIGHT
RAIN AND POSSIBLE LOWER CEILINGS WILL BE POSSIBLE LATE IN THE TAF
PERIOD AS ANOTHER WEAK SYSTEM, SIMILAR TO THIS MORNING, SETS UP
OVER THE REGION. KML

&&

.MARINE...SMALL FORERUNNERS TO A LONG PERIOD WESTERLY SWELL
IMPACTED THE COASTAL WATERS EARLY THIS MORNING AS INDICATED BY
BUOY OBSERVATIONS. THE SWELL WILL CONTINUE TO BUILD ACROSS THE
WATERS THIS MORNING BRINGING 10 TO 13 FT SEAS BY THIS EVENING. THE
RAPIDLY BUILDING SWELL WILL BRING A HIGH RISK FOR SNEAKER WAVES
THIS MORNING AND AFTERNOON. ANYONE PLANNING TO GO TO THE BEACH
NEEDS TO REMAIN ALERT AND KEEP A WATCHFUL EYE ON THE SURF WHICH
MAY APPEAR TO BE TRANQUIL AND SAFE AT TIMES. HOWEVER, LARGE AND
SURPRISING SETS OF WAVES WILL WASH OVER ROCKS, JETTIES, AND PUSH
MUCH FARTHER UP BEACHES. STAY MUCH FARTHER FROM THE WATER TODAY
AND NEVER TURN YOUR BACK ON THE OCEAN. THE SWELL WILL PEAK IN
MAGNITUDE ON FRIDAY MORNING WITH THE SEA STATE AROUND 12 TO 14 FT.
THE SWELL WILL THEN DIMINISH THROUGH THE WEEKEND INTO EARLY NEXT
WEEK. EXPECT SOUTHERLY WINDS FOR TODAY AND TONIGHT BUT THEN
MODERATE TO FRESH NORTH WINDS WILL PREVAIL THIS WEEKEND THROUGH
EARLY NEXT WEEK. KML

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
     SMALL CRAFT ADVISORY FROM 4 PM THIS AFTERNOON TO 3 AM PST SUNDAY
     FOR PZZ450-455-470-475.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
350 PM PST WED FEB 10 2016

.SYNOPSIS...MOSTLY DRY AND WARMER THAN NORMAL CONDITIONS ARE
EXPECTED THROUGH TOMORROW...ASIDE FROM PERIODIC SHOWERS THAT MAY
PRODUCE BRIEF LIGHT RAIN IN SPOTS. A COLD FRONT WILL BRING LIGHT
ACCUMULATING RAIN OVERNIGHT THURSDAY THROUGH MID DAY FRIDAY TO
PARTS OF HUMBOLDT...DEL NORTE...AND TRINITY COUNTIES. ADDITIONAL
LIGHT RAIN WILL BE POSSIBLE SUNDAY ACROSS THESE AREAS...WITH DRY
AND WARM CONDITIONS EXPECTED AGAIN MONDAY AND TUESDAY. MORE
SUBSTANTIAL RAIN IS POSSIBLE BY THE MIDDLE OF NEXT WEEK.

&&

.DISCUSSION...WHILE THE RIDGE CONTINUES TO HANG ON ACROSS THE WEST
COAST...IT IS BEGINNING TO SHOW SIGNS OF WEAKENING AS A LONGWAVE
TROUGH ACROSS THE NORTH PACIFIC SLOWLY MOVES EAST. A STEADY
STREAM OF MID AND HIGH LEVEL MOISTURE AHEAD OF AN APPROACHING
FRONTAL BOUNDARY AS RESULTED IN SCATTERED TO BROKEN CLOUD COVER
THROUGH THE REGION TODAY...WITH A FEW HIGH BASED SHOWERS
DEVELOPING ACROSS THE WATERS AND IN THE MOUNTAINS OF SISKIYOU AND
NORTHERN TRINITY COUNTY THIS AFTERNOON. TEMPERATURES TODAY WERE A
BIT COOLER ACROSS THE INTERIOR TODAY...LIKELY DUE TO THE WEAKENING
RIDGE AND INCREASED CLOUD COVER...BUT READINGS REMAIN WELL ABOVE
NORMAL AND VIRTUALLY UNCHANGED ALONG THE IMMEDIATE COAST. OVER THE
NEXT 24 HOURS...A PLUME OF INCREASED MID LEVEL MOISTURE WILL
CONTINUE MOVE INLAND...WHICH MAY RESULT IN PERIODIC BOUTS OF
SPRINKLES AND LIGHT RAIN SHOWERS...PARTICULARLY TOMORROW MORNING
AS A DIFFUSE WARM FRONT TRAVERSES THE REGION. HIGH ELEVATIONS
STAND THE BEST SHOT AT SEEING ANY ACCUMULATING RAINS AS LOW
ELEVATIONS WILL BE A BIT DRY...AND EVAPORATION WILL LIKELY PREVENT
THE VALLEYS FROM SEEING MUCH IF ANY ACCUMULATIONS. MEANWHILE...A
LAYER OF MARINE STRATUS HAS DEVELOPED APPROXIMATELY 15 TO 30
MILES OFFSHORE...AND IT IS PLAUSIBLE THAT SOME OF THIS STRATUS
COULD MOVE ONTO THE IMMEDIATE COAST OVERNIGHT TONIGHT. THE BEST
CHANCES FOR THIS OCCURRING WILL EXIST ALONG THE MENDOCINO
COAST...AND AS SUCH SOME PATCHY FOG HAS BEEN ADDED TO THE FORECAST
FOR OVERNIGHT TONIGHT AND TOMORROW NIGHT. BY OVERNIGHT TOMORROW...A
RAPIDLY WEAKENING COLD FRONT REMAINS ON TRACK TO BRING SOME LIGHT
ACCUMULATING RAINS TO THE REGION...PARTICULARLY TO TO AREAS NORTH
OF CAPE MENDOCINO. EXPECT ACCUMULATIONS RANGING FROM BETWEEN A
QUARTER TO A HALF AN INCH ACROSS THE HILLS OF DEL NORTE
COUNTY...TO ONLY A FEW HUNDREDTHS OF AN INCH IN SOUTHERN HUMBOLDT.
THIS RAIN WILL LIKELY LAST THROUGH MID DAY FRIDAY...AND TAPER OFF
THROUGH THE LATER AFTERNOON. TEMPERATURES ARE ALSO EXPECTED TO
COOL OFF SLIGHTLY FRIDAY AND SATURDAY...BUT WILL REMAIN AT LEAST
SLIGHTLY ABOVE NORMAL.

AFTER ANOTHER DRY DAY SATURDAY...A PASSING SHORTWAVE TO OUR NORTH
MAY RESULT IN SOME LIGHT RAIN SUNDAY ACROSS PRIMARILY DEL NORTE
AND NORTHERN HUMBOLDT COUNTIES...WITH ONLY LIGHT ACCUMULATIONS
EXPECTED. AFTER THIS WAVE PASSES THROUGH THE REGION...THE RIDGE
WILL RE-ASSERT ITSELF...RESULTING IN DRY AND WARM CONDITIONS
MONDAY AND TUESDAY. MODELS CONTINUE TO INDICATE THAT THIS RIDGE
WILL FINALLY BREAK DOWN WEDNESDAY...ALLOWING A COLD SYSTEM TO SAG
INTO THE REGION FROM THE NORTHWEST AND BRING MORE SUBSTANTIAL RAIN
AND LOWERING SNOW LEVELS. MANY UNCERTAINTIES REMAIN REGARDING
THIS SYSTEM A FULL WEEK AWAY...HOWEVER CONFIDENCE HAS INCREASED
ENOUGH TO INCREASE PRECIPITATION CHANCES TO LIKELY AT THIS STAGE
GIVEN THE RELATIVELY GOOD MODEL AGREEMENT. /BRC

&&

.AVIATION...VFR CONDITIONS WILL GENERALLY PREVAIL THROUGH THE
EVENING HOURS AS A FRONTAL BOUNDARY APPROACHES THE REGION. -SHRA
OR -DZ WILL BE POSSIBLE DURING THIS TIME FRAME BUT SHOULD BE
LIMITED TO THE COASTAL REGIONS AND TERMINALS. COME THURSDAY
MORNING...CHANCES FOR PRECIP SHOULD BE LIMITED TO DEL NORTE
COUNTY. OVERALL CURRENT THINKING IS THAT MVFR CONDITIONS WILL BE
POSSIBLE WITH ANY PRECIP ACTIVITY THAT TRACKS OVER THE COASTAL
AREAS. FOR THE INTERIOR REGION...PATCHY VALLEY FOG MAY DEVELOP
TONIGHT...HOWEVER...CONFIDENCE IS NOT HIGH IN IT OCCURRING AT
KUKI SINCE THE PREVIOUS FEW NIGHTS HAVE REPORTED VFR CONDITIONS.
KAR

&&

.MARINE...A WESTERLY SWELL WILL BUILD INTO NW CALIFORNIA WATERS
THURSDAY AND FRIDAY. THE FORERUNNERS WILL ARRIVE TONIGHT WITH
PERIODS AROUND 22-24 SECONDS...BUT WITH FAIRLY SMALL HEIGHTS.
SHORTER PERIOD WSW SWELL TONIGHT WILL MOST LIKELY MASK THE LONGER
PERIOD SWELL. THE SWELL WILL BUILD ON THU AND GRADUALLY BECOME THE
MOST ENERGETIC WAVE GROUP BY THU NIGHT. INITIALLY THE PRIMARY
THREAT WILL BE THE POTENTIAL FOR "SNEAKER WAVES" AND ENHANCED WAVE
RUN UP AT THE BEACHES ON THU. NWW3 INDICATES AT LEAST TWO SHORTER
PERIOD WAVE GROUPS COMMINGLING THROUGH THE DAY ON THU...HOWEVER.
THIS WAVE COMMINGLING MAY MITIGATE THE THREAT OF SUDDEN AND RAPID
SURGES IN SURF. THE INCOMING WESTERLY SWELL SHOULD BUILD TO 10 FT
OR MORE THU NIGHT AND A SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS
HAS BEEN HOISTED. EVEN THEN PERIODS WILL LIKELY BE FAIRLY LONG
WITH ONLY AVERAGE WAVE STEEPNESS. WAVE HEIGHTS WILL INCREASE AS
PERIODS DECREASE FRIDAY THROUGH SATURDAY. SEAS WILL MOST LIKELY
BECOME INCREASING STEEP AND HAZARDOUS ON FRIDAY AND PERHAPS INTO
SAT. THE SWELL SHOULD GRADUALLY DIMINISH OVER THE
WEEKEND...DROPPING BELOW 10 FT ON SUNDAY. HOWEVER THE MODELS
CONTINUE TO INDICATE A SLIGHT RAMP UP IN NORTHERLY WINDS SOUTH OF
THE CAPE WHICH MAY LAST LONG ENOUGH TO GENERATE SHORTER PERIOD
WAVES AND SEAS ABOVE 10 FT THROUGH SUN.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
317 AM PST WED FEB 10 2016

.SYNOPSIS...ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH THE
WEEK...WITH A MODEST COOLING TREND BY FRIDAY. SOME PATCHY DRIZZLE
IS POSSIBLE THIS MORNING ALONG THE DEL NORTE AND HUMBOLDT COASTS.
LIGHT RAIN IS LIKELY ACROSS THE NORTH FRIDAY AND FRIDAY
NIGHT...OTHERWISE NO SIGNIFICANT ADDITIONAL PRECIPITATION IS
EXPECTED THROUGH THE WEEKEND.

&&

.DISCUSSION...A WEAK FRONTAL BOUNDARY APPROACHING THE COAST THIS
MORNING WILL BRING CLOUDS TO THE AREA AND POSSIBLY SOME DRIZZLE
TO THE COAST. THE BEST CHANCE FOR DRIZZLE IS ON THE HUMBOLDT AND
DEL NORTE COUNTY COASTS. ONCE THIS BOUNDARY MOVES THROUGH CLOUDS
ARE EXPECTED TO DIMINISH...HOWEVER ANOTHER VERY WEAK BOUNDARY IS
EXPECTED LATER IN THE AFTERNOON AND OVERNIGHT. AGAIN RAINFALL IS
EXPECTED TO BE MINIMAL WITH ONLY A TRACE TO A FEW HUNDREDTHS.
PERIODS OF LIGHT RAIN OR DRIZZLE ARE EXPECTED TO CONTINUE INTO
THURSDAY. MOST LIKELY THE ONLY AREAS THAT WILL SEE ANY RAIN WILL
BE ALONG THE HUMBOLDT AND DEL NORTE COASTS.

THURSDAY NIGHT AND FRIDAY MORNING DEL NORTE COUNTY COULD SEE SOME
RAIN...BUT AMOUNTS LOOK TO BE LESS THAN A HALF OF AN INCH.
HUMBOLDT COUNTY COULD SEE SOME LIGHT RAIN...BUT AMOUNTS LOOK TO BE
LESS THAN A TENTH OF AN INCH. MODELS CONTINUE TO BE IN DECENT
AGREEMENT ON THIS...ALTHOUGH RAINFALL AMOUNTS VARY AND THE GFS IS
DRIER THAN THE CURRENT FORECAST.

SATURDAY LOOKS MAINLY DRY AS THE RIDGE REASSERTS ITSELF ACROSS THE
AREA. SATURDAY NIGHT INTO SUNDAY A WARM FRONT IS EXPECTED TO BUILD
IN ACROSS THE NORTHERN PORTION OF THE AREA. THIS WILL BRING FAIRLY
EXTENSIVE CLOUDS...BUT THE RAIN IS EXPECTED TO BE LESS THAN A
QUARTER OF INCH ONCE AGAIN. CONFIDENCE IS BELOW AVERAGE ON THIS
AS MODELS TEND TO STRUGGLE WITH WARM FRONTAL PRECIP A BIT MORE
THAN OTHER WEATHER PATTERNS.

MONDAY AND TUESDAY LOOK GENERALLY DRY...ALTHOUGH THE ECMWF HAS A
WEAK SHORTWAVE MOVING OVER THE TOP OF THE RIDGE AND BRINGING SOME
RAIN TO COASTAL OREGON...BUT NORTHERN CA REMAINS DRY AT THIS TIME.
MID TO LATE WEEK MODELS ARE INDICATING THE RIDGE WILL BREAK DOWN
AND FLOW WILL BECOME MORE ZONAL HINTING AT A RETURN TO A WETTER
PATTERN. MKK

&&

.AVIATION...VFR CONDITIONS PREVAILED EARLY THIS MORNING, HOWEVER,
VISIBLE SATELLITE IMAGERY SHOWED A LOW CLOUD DECK LOOMING OFF THE
NORTHWEST CALIFORNIA COAST. THIS COULD IMPACT KCEC AND KACV
THROUGH THE MORNING HOURS DROPPING AIRFIELD CONDITIONS TO MVFR
POSSIBLY IFR. 925 MB OMEGA MODEL DATA SUPPORTS THIS SHOWING AREAS
OF LIFT ESPECIALLY OVER DEL NORTE COUNTY THROUGH THE MID MORNING.
CONFIDENCE IS NOT HIGH WITH THESE LOW CEILINGS BUT ANYTHING THAT
DOES IMPACT THE NORTH COAST SHOULD LIFT WITH AFTERNOON MIXING WITH
MOSTLY VFR CONDITIONS EXPECTED THIS AFTERNOON. MID AND UPPER LEVEL
CLOUDS WILL INCREASE TONIGHT WITH THE APPROACH OF A WEAK FRONTAL
BOUNDARY WHICH WILL BRING SOME POSSIBLE DRIZZLE THIS EVENING. KML

&&

.MARINE...WINDS WILL REMAIN LIGHT TO MODERATE THROUGH THE WEEK AS
A BROAD RIDGE DOMINATES OVER THE WEST COAST. A WESTERLY SWELL WILL
BUILD ACROSS THE WATERS THURSDAY AND FRIDAY RESULTING IN LARGE
SEAS AROUND 12 TO 14 FT. SMALL CRAFT ADVISORIES FOR HAZARDOUS SEAS
WILL LIKELY BE ISSUED WITH SEAS EXPECTED TO RISE ABOVE 10 FT BY
THU AFTERNOON AND EVENING. THIS SWELL WILL ALSO BRING AN ELEVATED
THREAT FOR SNEAKER WAVES AS EARLY AS WEDNESDAY NIGHT WHEN THE
FORERUNNERS ARRIVE. THE SWELL WILL BUILD IN MAGNITUDE ON THU AND
THEN PEAK BY EARLY FRIDAY. ANYONE PLANNING TO GO TO THE BEACH
NEEDS TO REMAIN ALERT AND KEEP A WATCHFUL EYE ON THE SURF WHICH
MAY APPEAR TO BE TRANQUIL AND SAFE AT TIMES. THE SWELL WILL
SUBSIDE OVER THE WEEKEND...HOWEVER INCREASING NORTHERLY WINDS WILL
LIKELY PRODUCE A SLIGHT RAMP UP IN SHORT PERIOD WAVES BY SUNDAY.

NATIONAL WEATHER SERVICE EUREKA CA
758 PM PST TUE FEB 9 2016

.SYNOPSIS...ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH THE
WEEK...WITH A MODEST COOLING TREND BY FRIDAY. SOME PATCHY DRIZZLE
IS POSSIBLE WEDNESDAY MORNING ALONG THE DEL NORTE AND HUMBOLDT
COASTS. RAIN IS LIKELY ACROSS THE NORTH FRIDAY AND FRIDAY
NIGHT...OTHERWISE NO SIGNIFICANT ADDITIONAL PRECIPITATION IS
EXPECTED THROUGH THE WEEKEND.


&&

.UPDATE...HIGH RESOLUTION MODELS ARE INDICATING SOME DRIZZLE OR
LIGHT RAIN MAY DEVELOP ALONG THE HUMBOLDT AND DEL NORTE COASTS
EARLY WEDNESDAY MORNING. THUS CHANCES FOR PRECIPITATION HAVE BEEN
INCREASED IN THESE AREAS AND DRIZZLE HAS BEEN INTRODUCED TO THE
FORECAST. OTHERWISE THE FORECAST REMAIN ON TRACK AND THE PREVIOUS
DISCUSSION IS BELOW.



&&

.PREV DISCUSSION......ISSUED AT 325 PM PST...

DISCUSSION...WARM AND DRY CONDITIONS CONTINUE TO PREVAIL ALONG
THE WEST COAST AS A PERSISTENT AMPLIFIED RIDGE HOLDS STRONG.
TEMPERATURES TODAY HAVE BEEN SLIGHTLY COOLER THAN YESTERDAYS
RECORD VALUES AS EXPECTED...BUT REMAIN WELL ABOVE NORMAL WITH
COASTAL READINGS IN THE LOW 60S TO NEAR 70...AND INTERIOR VALLEY
TEMPERATURES IN THE UPPER 60S TO MID 70S. RELATIVELY DENSE HIGH
LEVEL CLOUD COVER HAS ALSO KEPT SKIES A BIT MORE OBSCURED THIS
AFTERNOON...ALTHOUGH IT APPEARS THAT THESE SHOULD CLEAR PRIOR TO
SUNSET FOR A FEW HOURS ALONG THE COAST.

OVER THE NEXT SEVERAL DAYS...A LONGWAVE TROUGH CURRENTLY LOCATED
ACROSS THE NORTHERN PACIFIC WILL GRADUALLY BREAK DOWN THE WEST
COAST RIDGE...SENDING SEVERAL SHORTWAVES/COLD FRONTS TOWARDS THE
COAST AS IT DOES. THESE FRONTS ARE ALL EXPECTED TO WEAKEN
SIGNIFICANTLY AS THEY BARREL INTO THE RIDGE...AND AS A
RESULT...MEANINGFUL ACCUMULATING RAINS ARE NOT EXPECTED UNTIL
FRIDAY AFTER THE RIDGE HAS WEAKENED SUBSTANTIALLY. EVEN
THEN...RAINFALL WILL BE MOSTLY LIMITED TO HUMBOLDT AND DEL NORTE
COUNTIES...WITH TOTAL ACCUMULATIONS NOT EXPECTED TO REACH ONE INCH
BY EARLY SATURDAY MORNING. UNTIL THEN...EXPECT ONLY VERY SLIM
CHANCES OF SPRINKLES NEAR THE COAST TONIGHT AS THE FIRST FRONT
DRAWS NEAR...AND PERHAPS A FEW LIGHT SHOWERS ACROSS THE INTERIOR
HILLS EARLY THURSDAY AS MOISTURE INCREASES AHEAD OF THE NEXT
FRONT. A BRIEF AND MODEST COOL DOWN IS ALSO EXPECTED FRIDAY AND
SATURDAY...HOWEVER THIS WILL LIKELY NOT EVEN BE ENOUGH TO BRING
TEMPERATURES BELOW SEASONAL AVERAGES.

BEYOND FRIDAY...THE UPPER RIDGE WILL BEGIN TO REASSERT ITSELF
ACROSS THE WEST COAST...WITH LIMITED OPPORTUNITIES FOR MEANINGFUL
RAIN. ON SUNDAY...A PROGRESSIVE SHORTWAVE WILL CLIMB THE TOP OF
THIS RIDGE AND IMPACT THE WASHINGTON/OREGON COAST...HOWEVER
IMPACTS FOR OUR REGION WILL BE LIMITED TO PERHAPS A BRIEF PERIOD
OF LIGHT RAIN ALONG THE REDWOOD COAST AND CLOUDY SKIES. MODEL
GUIDANCE CONTINUES TO SUGGEST THAT THE RIDGE WILL FINALLY BREAK
DOWN SOMETIME DURING THE MIDDLE OF NEXT WEEK...HOWEVER

325 PM PST TUE FEB 9 2016

.SYNOPSIS...ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH THE
WEEK...WITH A MODEST COOLING TREND BY FRIDAY. RAIN IS LIKELY
ACROSS THE NORTH FRIDAY AND FRIDAY NIGHT...NO SIGNIFICANT
ADDITIONAL PRECIPITATION IS EXPECTED THROUGH THE WEEKEND.

&&

.DISCUSSION...WARM AND DRY CONDITIONS CONTINUE TO PREVAIL ALONG
THE WEST COAST AS A PERSISTENT AMPLIFIED RIDGE HOLDS STRONG.
TEMPERATURES TODAY HAVE BEEN SLIGHTLY COOLER THAN YESTERDAYS
RECORD VALUES AS EXPECTED...BUT REMAIN WELL ABOVE NORMAL WITH
COASTAL READINGS IN THE LOW 60S TO NEAR 70...AND INTERIOR VALLEY
TEMPERATURES IN THE UPPER 60S TO MID 70S. RELATIVELY DENSE HIGH
LEVEL CLOUD COVER HAS ALSO KEPT SKIES A BIT MORE OBSCURED THIS
AFTERNOON...ALTHOUGH IT APPEARS THAT THESE SHOULD CLEAR PRIOR TO
SUNSET FOR A FEW HOURS ALONG THE COAST.

OVER THE NEXT SEVERAL DAYS...A LONGWAVE TROUGH CURRENTLY LOCATED
ACROSS THE NORTHERN PACIFIC WILL GRADUALLY BREAK DOWN THE WEST
COAST RIDGE...SENDING SEVERAL SHORTWAVES/COLD FRONTS TOWARDS THE
COAST AS IT DOES. THESE FRONTS ARE ALL EXPECTED TO WEAKEN
SIGNIFICANTLY AS THEY BARREL INTO THE RIDGE...AND AS A
RESULT...MEANINGFUL ACCUMULATING RAINS ARE NOT EXPECTED UNTIL
FRIDAY AFTER THE RIDGE HAS WEAKENED SUBSTANTIALLY. EVEN
THEN...RAINFALL WILL BE MOSTLY LIMITED TO HUMBOLDT AND DEL NORTE
COUNTIES...WITH TOTAL ACCUMULATIONS NOT EXPECTED TO REACH ONE INCH
BY EARLY SATURDAY MORNING. UNTIL THEN...EXPECT ONLY VERY SLIM
CHANCES OF SPRINKLES NEAR THE COAST TONIGHT AS THE FIRST FRONT
DRAWS NEAR...AND PERHAPS A FEW LIGHT SHOWERS ACROSS THE INTERIOR
HILLS EARLY THURSDAY AS MOISTURE INCREASES AHEAD OF THE NEXT
FRONT. A BRIEF AND MODEST COOLDOWN IS ALSO EXPECTED FRIDAY AND
SATURDAY...HOWEVER THIS WILL LIKELY NOT EVEN BE ENOUGH TO BRING
TEMPERATURES BELOW SEASONAL AVERAGES.

BEYOND FRIDAY...THE UPPER RIDGE WILL BEGIN TO REASSERT ITSELF
ACROSS THE WEST COAST...WITH LIMITED OPPORTUNITIES FOR MEANINGFUL
RAIN. ON SUNDAY...A PROGRESSIVE SHORTWAVE WILL CLIMB THE TOP OF
THIS RIDGE AND IMPACT THE WASHINGTON/OREGON COAST...HOWEVER
IMPACTS FOR OUR REGION WILL BE LIMITED TO PERHAPS A BRIEF PERIOD
OF LIGHT RAIN ALONG THE REDWOOD COAST AND CLOUDY SKIES. MODEL
GUIDANCE CONTINUES TO SUGGEST THAT THE RIDGE WILL FINALLY BREAK
DOWN SOMETIME DURING THE MIDDLE OF NEXT WEEK...HOWEVER

NATIONAL WEATHER SERVICE EUREKA CA
355 PM PST MON FEB 8 2016

.SYNOPSIS...ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH THE
WEEK...WITH A MODEST COOLING TREND EXPECTED OVER THE WEEKEND.
ASIDE FROM A CHANCE OF LIGHT RAIN FRIDAY AND FRIDAY NIGHT...NO
SIGNIFICANT PRECIPITATION IS EXPECTED THROUGH NEXT MONDAY.

&&

.DISCUSSION...A LARGE...PERSISTENT RIDGE CONTINUES TO RESULT IN
UNSEASONABLY WARM AND DRY CONDITIONS THROUGHOUT THE WEST COAST
TODAY...WITH TEMPERATURES NEAR AND ABOVE ALL TIME RECORDS IN SOME
PLACES IN NORTHWEST CALIFORNIA. PERSISTENT OFFSHORE WINDS ARE ALSO
CONTRIBUTING TO THE WELL ABOVE NORMAL TEMPERATURES...PARTICULARLY
NEAR THE COAST WHERE MANY LOCATIONS HAVE CLIMBED INTO THE MID TO
UPPER 70S...AND EVEN THE LOW 80S IN A FEW FAVORABLY LOCATED SPOTS.
WFO EUREKA...CRESCENT CITY...AND UKIAH HAVE ALL SET FEBRUARY 8
RECORDS FOR HIGH TEMPERATURES AS OF 3 PM WITH MAXIMUMS OF
72...75...AND 82 DEGREES RESPECTIVELY. THESE ARE LIKELY TO BE THE
FINAL NUMBERS AT THE END OF THE DAY...HOWEVER THERE IS AN OUTSIDE
CHANCE THAT PERSISTENT OFFSHORE WINDS ALONG THE COAST COULD CAUSE
TEMPERATURES TO SPIKE AGAIN IN A FEW PLACES BEFORE THE END OF THE
DAY. CONDITIONS WILL BE SIMILAR TOMORROW AS SOUTHEAST WINDS WILL
LIKELY CONTINUE...ALTHOUGH SLIGHTLY LOWERING 1000-500 MB THICKNESSES
WILL LIKELY KEEP TEMPERATURES A FEW DEGREES COOLER THAN THEY WERE
TODAY.

BY LATE TOMORROW...THE UPPER RIDGE WILL BEGIN A GRADUAL PROCESS OF
WEAKENING AS A LONGWAVE TROUGH ACROSS THE NORTHERN PACIFIC
ATTEMPTS TO MOVE WESTWARD. AS THIS OCCURS...A SERIES OF WEAKENING
FRONTAL BOUNDARIES WILL ATTEMPT TO MOVE ONSHORE...FINALLY
SUCCEEDING IN DOING SO OVERNIGHT FRIDAY/EARLY SATURDAY AS THE
GREATLY DIMINISHED TROUGH FINALLY CLIMBS UP AND OVER THE RIDGE
INTO THE PACIFIC NORTHWEST. WHILE SOME LIGHT DRIZZLE WILL BE
POSSIBLE NEAR THE COAST AT TIMES PRIOR TO THIS...LATE FRIDAY IS
LIKELY THE REGIONS BEST SHOT AT MEASURABLE PRECIPITATION UNTIL
SOMETIME IN THE MIDDLE OF NEXT WEEK...WITH ONLY LIGHT AMOUNTS
EXPECTED FROM CAPE MENDOCINO NORTHWARD. BEYOND SATURDAY...THE
