AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
437 AM PST THU DEC 10 2015

.SYNOPSIS...SCATTERED RAIN SHOWERS AND MOUNTAIN SNOW SHOWERS WILL
PERSIST TODAY THROUGH FRIDAY. ISOLATED THUNDERSTORMS ARE EXPECTED
NEAR THE COAST WITH THE STRONGER SHOWERS AND STORMS CAPABLE OF
PRODUCING SMALL HAIL. ANOTHER POTENT STORM SYSTEM WILL BRING MORE
HEAVY RAIN TO THE REGION THIS WEEKEND.

&&

.SHORT TERM...(THROUGH FRIDAY NIGHT)...COLDER AIR IS FUNNELING OVER
NORTHWEST CALIFORNIA BEHIND A STRONG COLD FRONT BRINGING 500MB
TEMPERATURES OF BETWEEN -27 AND -30C. AS THIS OCCURS...INSTABILITY
GENERATED BY THE COLDER AIR MOVING OVER THE RELATIVELY WARM COASTAL
WATERS WILL RESULT IN A TRANSITION FROM THE STRATIFORM RAIN WE
SAW THIS MORNING TO NUMEROUS CONVECTIVE SHOWERS...LIKELY ARRIVING
IN MULTIPLE ROUNDS THROUGH LATE FRIDAY. GIVEN THE COLD
TEMPERATURES ALOFT AND INSTABILITY PROJECTIONS OF 500-800 J/KG
ACROSS THE WATERS AND ALONG THE IMMEDIATE COAST...SMALL HAIL IS
LIKELY WITH THIS ACTIVITY...ALONG WITH OCCASIONAL LIGHTNING
STRIKES. THERE MAY BE ENOUGH INSTABILITY AND WINDS ALOFT TO
SUPPORT SOME STRONGER STORMS AND THE STORM PREDICTION CENTER HAS
PLACED THE NORTHWEST CALIFORNIA COAST IN A MARGINAL RISK FOR
STRONG STORMS THROUGH TONIGHT.

MEANWHILE...SNOW LEVELS WILL QUICKLY DROP THROUGH THE DAY
TODAY...REACHING THEIR LOWEST LEVELS OVERNIGHT TONIGHT AND EARLY
FRIDAY MORNING. JUST HOW LOW THESE SNOW LEVELS WILL DROP IS A BIT OF
A QUESTION MARK...AS MODELS TYPICALLY PERFORM POORLY IN THESE
SITUATIONS IN MANY AREAS OF NW CA. IN PARTICULAR...PARTS OF EASTERN
TRINITY COUNTY ALONG 299 AND HIGHWAY 3 TEND TO SEE LOWER SNOW LEVELS
THAN THE SURROUNDING AREA. THIS HAS OCCURRED THE PAST TWO WINTER
WEATHER EVENTS WHERE LOCATIONS SUCH AS OREGON MOUNTAIN AND TRINITY
CENTER SAW ACCUMULATING SNOW WHEN MODEL FORECASTED SNOW LEVELS DID
NOT SUGGEST THAT THIS WOULD OCCUR. THUS WINTER WEATHER ADVISORIES
HAVE BEEN ISSUED FOR TRINITY COUNTY TO 2000 FEET...NORTH COAST
INTERIOR TO 2500 FEET...AND INTERIOR MENDOCINO COUNTY TO 3000
FEET...BEGINNING THIS MORNING AND LASTING THROUGH FRIDAY EVENING. AS
MENTIONED PREVIOUSLY...THE LOWEST SNOW LEVELS WILL LIKELY OCCUR
OVERNIGHT TONIGHT AND EARLY FRIDAY MORNING...AND DURING THIS TIME
FRAME A QUICK COUPLE OF INCHES OF SNOW WILL BE POSSIBLE AS LOW AS
THE VALLEY FLOOR IN THE AREAS MENTIONED ABOVE. SNOW LEVELS WILL
LIKELY LIFT A BIT DURING THE AFTERNOON FRIDAY AS TEMPERATURES
WARM...BUT HIGHER PASSES SUCH AS SOUTH FORK ALONG HIGHWAY 36 AND
SCOTT MOUNTAIN ON HIGHWAY 3 WILL STILL BE COLD ENOUGH TO SEE
CONTINUED SNOW ACCUMULATIONS THROUGH THE DAY FRIDAY. IN THE LOWER
LYING AREAS INCLUDED IN THE ADVISORIES...IE 2000 TO 3000 FEET...SNOW
ACCUMULATION WILL LIKELY ONLY BE ON THE ORDER OF 1 TO 3 INCHES AS
THE WINDOW OF SUFFICIENTLY COLD TEMPERATURES WILL BE RELATIVELY
BRIEF. HOWEVER...ABOVE 3500 FEET ACCUMULATIONS OF 3 TO 7 INCHES WILL
BE POSSIBLE AS SHOWERS ARE EXPECTED TO BE FAIRLY ROBUST AND
PERSISTENT THROUGH FRIDAY AFTERNOON...AND POSSIBLY EVEN INTO EARLY
SATURDAY MORNING. THE HIGHER PEAKS OVER 4500 MAY SEE EVEN MORE
SNOW.

IN ADDITION TO THE WINTER WEATHER CONCERNS...A NON TRIVIAL AMOUNT OF
RAIN WILL CONTINUE TO FALL AT LOWER ELEVATIONS DUE TO THE PERSISTENT
SHOWERS. WHILE RIVERS WILL LIKELY REACH THEIR PEAK FLOWS BY THIS
AFTERNOON FOLLOWING THE PRIMARY FRONTAL BAND...PERSISTENT SHOWER
ACTIVITY THROUGH FRIDAY WILL LIKELY RESULT IN A DELAYED RECESSION OF
WATER LEVELS. IN ANY CASE THOUGH...CURRENT PROJECTIONS CONTINUE TO
INDICATE THAT MAIN STEM RIVERS WILL NOT RISE TO MONITOR LEVELS.
BRC/RPA

.LONG TERM...(SATURDAY THROUGH FRIDAY)...THE MAIN STORY THIS COMING
WEEKEND WILL BE ANOTHER STRONG STORM SYSTEM AND POTENTIAL
ATMOSPHERIC RIVER THAT IS FAVORED BY THE MODELS TO IMPACT OUR
REGION WITH HEAVY RAINFALL AND POSSIBLE GUSTY WINDS. MODELS HAVE
ONLY TRENDED TOWARD MORE RAINFALL IN THE LAST 24 HOURS...SO
CONFIDENCE IS INCREASING THAT SIGNIFICANT RAIN MAY DEVELOP WITH
AREAL FLOODING AND POTENTIALLY RISES ON SOME MAIN STEM RIVERS INTO
MONITOR STAGE. THERE REMAINS SEVERAL DAYS UNTIL THIS STORM
ARRIVES...SO THE DETAILS WILL LIKELY CHANGE INCLUDING THE FORECAST
RAIN AMOUNTS...BUT MODELS NOW PREDICT A WARM FRONT TO FIRST BEGIN
TO IMPACT THE SOUTHERN OREGON AND NORTHWEST CALIFORNIA COAST
DURING THE DAY SATURDAY. A COLD FRONT WILL THEN SLIDE THIS FRONT
SOUTH TARGETING THE BEST VAPOR TRANSPORT OVER NORTHWEST CALIFORNIA
AT THE SAME TIME AS A SECONDARY...POTENTIALLY STRONG LOW PRESSURE
SYSTEM ADVANCES TOWARD THE COAST. IF THIS LOW DEVELOPS AS FORECAST
IN THE MODELS...THE FRONT WILL THEN STALL OVER NORTHWEST
CALIFORNIA SATURDAY NIGHT BRINGING CONTINUOUS HEAVY RAINFALL FOR
SOME PORTIONS OF THE REGION. FOR NOW THE TARGET IS FROM CAPE
MENDOCINO TO THE OREGON BORDER...BUT ONLY A SLIGHT DEVIATION IN
STORM TRACK FROM CURRENT MODEL GUIDANCE WOULD CHANGE THE BULLSEYE
OF PRECIPITATION SIGNIFICANTLY. THIS LOW WILL THEN MOVE INLAND
AND PUSH ANOTHER COLD FRONT SOUTH AND FINALLY BRING AN END TO THE
HEAVY RAIN ON SUNDAY. THE WEATHER PREDICTION CENTER CURRENTLY
FORECASTS OVER 6 INCHES OF RAIN FOR THE HARDEST HIT LOCATIONS. IN
ADDITION...IF THE LOW PRESSURE SYSTEM STRENGTHENS OFF THE
IMMEDIATE COAST SATURDAY NIGHT THERE COULD BE ANOTHER STRONG WIND
EVENT. THIS IS DEFINITELY AN EVENT THAT PEOPLE SHOULD PAY CLOSE
ATTENTION TO AND FOLLOW UPDATED FORECASTS AS THE FORECAST DETAILS
BECOME CLEARER.

AFTER THE FRONT MOVES INLAND ON SUNDAY...NORTHWESTERLY FLOW ALOFT
WILL MOVE OVER NORTHWEST CALIFORNIA AS A TROUGH SETTLES INTO THE
INTERMOUNTAIN WEST. THIS WILL BRING MUCH COOLER TEMPERATURES TO THE
REGION WITH LOWS BACK INTO THE 20S ACROSS THE INTERIOR AND 30S NEAR
THE COAST. SHORTWAVES IN THE UPPER LEVEL FLOW MAY BRING PERIODS OF
SHOWERS OR LIGHT RAIN/SNOW ACTIVITY THROUGH THE END OF THE WORK
WEEK. RPA

&&

.AVIATION...A COOLER AIR MASS WILL GENERATE OCCASIONAL SHOWERS WITH
PERIODIC MVFR CONDITIONS TODAY AND TONIGHT. ISOLATED TSTMS HAVE BEEN
OCCURRING OVERNIGHT WELL OFFSHORE. SOME OF THESE T-STORMS MAY MOVE
INTO OR AROUND THE COASTAL TERMINALS TODAY AND TONIGHT. A LOW
PRESSURE SYSTEM TO OUR NORTH WILL GENERATE GUSTY W TO SW WINDS
THROUGH THE DAY. THE WINDS SHOULD LAY DOWN TONIGHT.

&&

.MARINE...AN IMPRESSIVE LOOKING STORM WELL TO OUR NW HAS BEEN
GENERATING VERY LARGE SEAS. AS OF 3AM PST...BUOY #2 250 WEST
OF CAPE BLANCO OREGON HAS BEEN REPORTING SEAS NEAR 40 FEET WITH
WESTERLY WINDS HOWLING AT 40-50KT. THE REPORTS FROM BUOY #2 HAS BEEN
REALLY CLOSE TO THE MODEL FORECAST. THUS WILL CONTINUE TO CLOSELY
FOLLOW THE NWW3 GUIDANCE WHICH HAS THE SWELL BUILDING TO 25 TO 29
FEET AT 15 TO 17 SECONDS THIS AFTERNOON AND EVENING. WE HAVE NOT
SEEN SWELL OF THIS MAGNITUDE FOR QUITE SOME TIME AND A HIGH SURF
WARNING REMAINS IN EFFECT OF BREAKERS OF 30+ FEET. A WARNING FOR
HAZARDOUS SEAS IS IN EFFECT AS WELL THROUGH FRI NIGHT. THE SWELL
SHOULD START TO SUBSIDE BELOW 20 FT OVER THE WEEKEND. HOWEVER
ANOTHER POTENT STORM FRONT WILL IMPACT THE WATERS WITH HIGH WINDS
AND HEAVY SEAS THIS WEEKEND. THE SWELL WITH THIS STORM DOES NOT LOOK
AS IMPRESSIVE...HOWEVER WITH THE ADDED CONTRIBUTION FROM STRONG SW
AND NW WINDS...SEAS MAY INDEED SPIKE UP TO 20 FEET OR MORE AGAIN
THIS WEEKEND.

&&

.HYDROLOGY...A FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING
FOR HUMBOLDT AND DEL NORTE COUNTIES WITH HEAVY RAIN SHOWERS AND
THUNDERSTORMS EXPECTED THROUGH THE DAY. HOWEVER SHOWERS CURRENTLY
REMAIN ISOLATED ENOUGH OFF THE COAST THAT FLOODING RAINS WOULD
LIKELY NOT DEVELOP. IF SHOWER ACTIVITY DOES NOT INCREASE IN
COVERAGE SIGNIFICANTLY OVER THE NEXT FEW HOURS THE FLOOD WATCH
WILL BE EXPIRED EARLY.

MODELS ARE INDICATING THE POTENTIAL FOR MORE HEAVY RAINFALL THIS
WEEKEND...WITH THE PRIMARY TARGET OVER DEL NORTE AND HUMBOLDT
COUNTIES AT THIS TIME. IF THE MODEL GUIDANCE IS CORRECT THERE WILL
BE ANOTHER CHANCE FOR FLOODING RAINS THIS WEEKEND WITH AREAL
FLOODING AND RAPID RISES ON MAIN STEM RIVERS.
