AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
307 PM PST THU JAN 21 2016

.SYNOPSIS...AN APPROACHING COLD FRONT WILL MOVE ONSHORE TONIGHT
INTO FRIDAY MORNING BRINGING A PERIOD OF HEAVY RAIN. DEEPENING
LOW PRESSURE OVER THE EASTERN PACIFIC WILL BRING MORE RAIN AND
GUSTY WINDS FRIDAY NIGHT FOLLOWED BY LOWERING SNOW LEVELS AND
SHOWERS ON SATURDAY.

&&

.DISCUSSION...

.SHORT TERM...SATELLITE DATA INDICATED A LONG MOISTURE PLUME
OFFSHORE THIS AFTERNOON. WINDS HAVE BEEN GUSTING OVER MAINLY
OVER THE HIGHER ELEVATIONS IN THE WARM/DRY SECTOR PROCEEDING THE
FRONT. SOUTHERLY WINDS SHOULD INCREASE A TAD THIS EVENING AS THE
FRONT APPROACHES AND A COASTAL JET DEVELOPS. IT WILL BE MARGINAL FOR
AN ADVISORY ALONG THE COAST WITH GUSTS REACHING 40 TO 45 MPH THIS
EVENING FOR AN HOUR OR TWO. WITH 925-850MB WINDS EXPECTED TO PEAK
NEAR 50KT THIS EVENING WILL HOIST A WIND ADVISORY FOR THE COAST.
THE STRONG WINDS ALOFT MAY NOT MIX DOWN TO MEAN SEA LEVEL AS
DAYTIME HEATING WANES. THE SOUTHERLY DOWNSLOPE FLOW WILL PROBABLY
DELAY THE HEAVY RAIN ALONG THE COAST AROUND EUREKA THIS EVENING.
ALL INDICATIONS ARE FOR HEAVIER RAIN TO DEVELOP OVERNIGHT AS THE
MOIST BAND MOVES ONSHORE. WE ARE EXPECTING 0.75 TO 1.5 INCHES OF
RAIN TONIGHT INTO FRI MORNING. SATELLITE IMAGERY AND MODEL DATA
ALSO INDICATES SOME INSTABILITY WITH THIS FRONT AS IT MOVES
THROUGH LATE TONIGHT...SO MAINTAINED A SLIGHT CHANCE OF
THUNDERSTORMS IN THE COASTAL WATERS AND COASTAL AREAS NORTH OF
CAPE MENDOCINO. THE RAIN WILL EASE UP AND TRANSITION TO SCATTERED
FRIDAY MORNING AS A ANOTHER STORM SYSTEM BEGINS TO RAMP UP
OFFSHORE. THIS NEXT LOW PRESSURE SYSTEM WILL QUICKLY APPROACH
FRIDAY AFTERNOON AND EVENING BRINGING MORE RAIN AND WINDY
CONDITIONS FRIDAY NIGHT. THIS VERTICALLY STACKED LOW WILL MOST
LIKELY FILL AS IT APPROACHES THE COAST. IT WILL STILL GENERATE
GUSTY SOUTH WINDS...AND ANOTHER WIND ADVISORY WILL NEED TO BE
CONSIDERED. THE HIGHER RESOLUTION MODELS MAY HAVE A BETTER HANDLE
ON THE STRENGTH OF THE WINDS AS THE STORM GETS CLOSER. COLD AIR
ALOFT WILL ARRIVE FRIDAY NIGHT AND SAT. THERE ARE INDICATIONS OF
INSTABILITY AND THE POTENTIAL FOR ISOLATED TSTMS AS 500MB TEMPS
FALL TO AROUND -25C. SNOW LEVELS SHOULD DROP TO 3500 TO 4500 FEET
ON SATURDAY WITH PERHAPS 2 TO 6 INCHES OF SNOW ON SATURDAY OVER
THE MOUNTAIN TOPS. THE ONLY PASSES THAT MAY BE IMPACTED BY SNOW
ARE SOUTH FORK MOUNTAIN PASS ON ROUTE 36 AND SCOTT MOUNTAIN PASS
ON ROUTE 3. CONFIDENCE IS NOT HIGH THE SNOW WILL CREATE AN IMPACT
FOR NW CALIFORNIA...SO WILL NOT ISSUE A WINTER STORM WATCH.
PRECIP WILL START TO WIND DOWN SATURDAY NIGHT AS THE TROUGH ALOFT
HEADS EASTWARD AND A RIDGE BUILDS OVER THE AREA. SUNDAY AND SUNDAY
NIGHT LOOK DRY FOR THE MOST PART...HOWEVER MODELS DO SHOW A WEAK
SYSTEM MOVING OVER THE RIDGE. SOME LIGHT RAIN OR SPRINKLES MAY
DEVELOP IN THE FAR NORTHERN MOST ZONES...MAINLY IN DEL NORTE
COUNTY AND FAR NORTHERN HUMBOLDT COUNTY. THE ECMWF HAS THE PRECP
FARTHER SOUTH WHILE THE GFS KEEPS THE PRECIP OFFSHORE AND IN SW
OREGON.

.LONG TERM (MON THROUGH THU)...RIDGING WILL DEVELOP OVER THE WEST
COAST MON AND HOLD THROUGH MID NEXT WEEK. THERE IS A CHANCE FOR
LIGHT SPOTTY RAIN FROM TIME TO TIME AS A COUPLE OF WEAKENING
FRONTS RUN UP OVER THE TOP OF THE RIDGE. WITH THE MEAN RIDGE IN
PLACE...THESE SHORTWAVES WILL PROBABLY DAMPEN OUT SUBSTANTIALLY.
OVERALL IT IS LOOKING LIKE A STRETCH OF MOSTLY DRY WEATHER...BUT
STILL TOO EARLY TO COMPLETELY RULE OUT THE POSSIBILITY OF SOME
RAIN. THE RIDGE SHOULD FLATTEN OUT AND SHIFT SOUTHWARD LATE IN THE
WEEK ALLOWING A MOIST WEST-SOUTHWEST FLOW TO DEVELOP AROUND THU OR
FRI FOR BETTER CHANCES FOR MORE SIGNIFICANT RAIN.

&&

.AVIATION...VFR CONDITIONS AND MODERATE TO MODERATE AND GUSTY WINDS WILL
CONTINUE AT KCEC, KACV AND KUKI THROUGH THIS AFTERNOON. SHOWERS WILL MOVE
ACROSS THE AREA THIS EVENING AND OVERNIGHT AS A COLD FRONT APPROACHES AND
MOVES THROUGH THE REGION. THE SHOWERS WILL REDUCE CEILINGS AND VISIBILITIES
TO MVFR  AND TEMPORARY IFR CONDITIONS AT KCEC, KACV AND KUKI THIS EVENING
AND OVERNIGHT. THE WINDS WILL BECOME MODERATE AND GUSTY THIS AFTERNOON
AND EVENING AS THE COLD FRONT MOVES THROUGH THE AREA.

&&

.MARINE...A COLD FRONT WILL MOVE ACROSS THE REGION TONIGHT. ANOTHER
COLD FRONT WILL MOVE ACROSS THE REGION FRIDAY NIGHT. THE WINDS AND
SEAS HAVE INCREASED TODAY AND WILL INCREASE TONIGHT. THE WINDS AND
SEAS WILL DECREASE SATURDAY. THEREFORE ELEVATED WINDS AND SEAS WILL
PERSIST ACROSS THE WATERS THROUGH SATURDAY. THE HIGHEST WINDS AND
SEAS WILL BE ACROSS THE OUTER WATERS. SMALL CRAFT ADVISORIES WILL
CONTINUE IN EFFECT ACROSS THE NEAR SHORE WATERS THROUGH SATURDAY
DUE TO ELEVATED WINDS AND/OR SEAS. GALE WARNINGS WILL CONTINUE IN
EFFECT ACROSS THE OUTER WATERS THROUGH FRIDAY MORNING DUE TO ELEVATED
WINDS. SMALL CRAFT ADVISORIES ARE LIKELY ACROSS THE OUTER WATERS
FRIDAY AND SATURDAY. THE WINDS AND SEAS WILL DIMINISH SATURDAY AND
SUNDAY AS A HIGH PRESSURE RIDGE BUILDS ACROSS THE REGION. HOWEVER
THE WINDS AND SEAS WILL INCREASE EARLY NEXT WEEK AS A COLD FRONT
APPROACHES THE WATERS.

&&

.HYDROLOGY...
LATEST RFC GUIDANCE HAS THE EEL RIVER AT FERNBRIDGE
REACHING MONITOR STAGE ON SATURDAY. ALL THE OTHER MAIN-STEM RIVERS
ARE FORECAST TO REMAIN BELOW MONITOR STAGE. THIS WILL NEED TO BE
CLOSELY MONITORED IF WE RECEIVE MORE RAIN THAN ANTICIPATED. ALL
THE MAIN-STEM RIVERS AND SMALLER STREAMS WILL SEE MINOR TO
MODERATE RISES OVER THE NEXT COUPLE OF DAYS AND RESIDENTS IN FLOOD
PRONE AREAS SHOULD CONTINUE TO MONITOR PUBLIC AND RIVER FORECASTS.

.COASTAL/SURF ZONE...
WITH THE APPROACHING FULL MOON...ASTRONOMICAL HIGH TIDES HAVE
BEEN INCREASING AND WILL PEAK ON FRIDAY. TIDAL ANOMALIES SHOULD
INCREASE AS WELL DUE TO BUILDING WEST SWELL AND SUSTAINED
SOUTHERLY WINDS. ANOTHER COASTAL FLOOD ADVISORY AROUND HUMBOLDT
BAY WILL PROBABLY BE NECESSARY FRIDAY MORNING IF THE ANOMALIES
REMAIN AT OR ABOVE 8/10'S OF A FOOT. MINOR FLOODING IN KING
SALMON...THE ARCATA BOTTOMS AND OTHER LOW LYING AREAS AROUND
HUMBOLDT BAY WILL BE POSSIBLE. ASTRONOMICAL HIGH TIDES WILL TREND
DOWNWARD OVER THE WEEKEND...HOWEVER IF THE ANOMALIES DO NOT TREND
DOWNWARD...ANOTHER ADVISORY MAY BE REQUIRED ON SATURDAY.
