AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
302 AM PST FRI DEC 27 2013

.SYNOPSIS...DRY WEATHER WILL CONTINUE THROUGH NEXT WEEK
AS A STRONG RIDGE ALOFT DOMINATES.

&&

.DISCUSSION...SATELLITE IMAGERY SHOWED MAINLY CLEAR SKIES OVER
NORTHWESTERN CALIFORNIA THIS MORNING. HIGH CLOUDS HAVE BEEN
GRADUALLY MOVING TOWARD THE COAST AND WILL SPREAD OVER MOST
OF THE FORECAST AREA TODAY. THE CIRRUS WAS BEING GENERATED
IN SW FLOW AHEAD OF A WEAKENING UPPER LEVEL TROUGH. THIS
TROUGH WILL SERVE TO BUST DOWN THE OFFSHORE PRESSURE GRADIENTS
WHICH WILL RESULT IN SEVERAL DEGREES OF COOLING TODAY. PLACES
THAT SAW LOWER TO MID 70S THE LAST COUPLE DAYS SHOULD SEE ABOUT
10F OF COOLING. THE CIRRUS WILL DECREASE TONIGHT AS THE TROUGH
HEADS SOUTHEAST AND A RIDGE BUILDS BEHIND IT. WITH LIGHT NORTHERLY
FLOW RETURNING AND THE BOUNDARY LAYER MOISTENING UP TONIGHT, THERE
WILL BE BETTER CHANCES FOR LOW CLOUD AND FOG GROWTH ALONG THE
COAST. LIGHT NE FLOW LOOKS TO DEVELOP TONIGHT WHICH WILL MOST
LIKELY LIMIT GROWTH AND CONFINE LOW CLOUDS OR FOG TO THE GREATER
EUREKA AREA AND DELTA. EVEN ON SATURDAY AS NORTHERLY FLOW
INCREASES...THERE APPEARS TO BE A FAIR AMOUNT OF BOUNDARY LAYER
HUMIDITY. THE MECHANICAL MIXING DOES LOOK SUFFICIENT TO SCOUR MOST
OF IT OUT THROUGH THE DAY. OFFSHORE EASTERLY FLOW SHOULD FIRMLY
RE-ESTABLISH SAT NIGHT INTO SUNDAY AS A NEW THERMAL LOW PRESSURE
TROUGH DEVELOPS AND PUSHES OFFSHORE THE COAST. THIS LOW PRESSURE
TROUGH SHOULD REMAIN OFFSHORE THROUGH SUNDAY NIGHT. EXPECT SEVERAL
DEGREES OF WARMING OVER THE UPPER ELEVATIONS AGAIN...WITH PERHAPS
A FEW DEGREES OF WARMING IN THE VALLEYS ON SUNDAY.

&&

.PREVIOUS LONG TERM DISCUSSION (MONDAY THROUGH THURSDAY)...MONDAY
THE GFS SHOWS A WEAK SHORTWAVE SQUASHING THE RIDGE. THE ECMWF IS
ABOUT 24 HOURS SLOWER AND WEAKER WITH THIS SHORTWAVE. EITHER WAY
THERE IS LITTLE TO NO PRECIP ASSOCIATED WITH THESE SYSTEMS AND
THERE WILL ONLY BE SUBTLE CHANGES IN THE WIND...COASTAL CLOUD
COVER AND TEMPERATURES. WEDNESDAY AND THURSDAY THE ECMWF HOLDS
ONTO THE RIDGE AND THE GFS IN PRINCIPLE DOES THE SAME
THING...HOWEVER HEIGHTS ARE A BIT LOWER AS A WEAK SHORTWAVE MOVES
BY TO THE NORTH. IN GENERAL WE FAVOR THE ECMWF SOLUTION THAT IS
SLOWER AND KEEPS A MORE PERSISTENT RIDGE OVER THE WEST COAST AS WE
HAVE SEEN FOR THE LAST MONTH OR SO. OVERALL THE PATTERN LOOKS TO
CONTINUE TO BE DRY WITH A RIDGE OVER THE WEST COAST FOR MUCH OF
THE PERIOD. SOME WEAK SHORTWAVES TRY TO MOVE THROUGH BRINGING
COASTAL CLOUDS AND POSSIBLY A FEW HIGH CLOUDS TO THE AREA.
CONFIDENCE IS LOW ON THE TIMING OF THESE. THE INTERIOR VALLEYS
WILL LIKELY CONTINUE TO SEE LOW CLOUDS AND FOG...ALTHOUGH THE
COVERAGE WILL VARY SLIGHTLY. MKK

&&

.AVIATION...VFR CONDITIONS WILL PERSIST THROUGH TODAY EXCEPT FOR
SOME PATCHY FOG AROUND SUNRISE. ONLY EXCEPTION IS DEEPER RIVER
VALLEYS OF INTERIOR NORTHWEST CALIFORNIA. AT LOCATIONS SUCH AS
WEAVERVILLE AND TRINITY CENTER, EXPECT LOCALIZED LIFR VSBYS AND CIGS
TILL ABOUT 0900. SOME MID-CLOUDS SHOULD MOVE THROUGH TODAY WITH A
MID-LEVEL SHORTWAVE TROUGH, BUT THOSE CLOUD BASES SHOULD STAY ABOVE
10000 FT ASL. A FRONT WILL WEAKEN OFF THE COAST TODAY AND MOST LOW
LEVEL MOISTURE STAYS OFFSHORE. ONLY EXCEPTION IS THIS EVENING AROUND
LOWER END OF EEL RIVER VALLEY IN UPSLOPE FLOW WHERE IFR CIGS COULD
DEVELOP. THESE CIGS COULD THEN EXPAND NORTH TO KACV AFTER MIDNIGHT.
AAD/DEAN

&&

.MARINE...SCATTEROMETER OBSERVATION FROM 10PM THU SHOWED VIRTUALLY
CALM WINDS OVER THE OCEAN WITHIN 60 MILES OF THE COAST. AN
APPROACHING WEAKENING FRONT WILL PRODUCE LIGHT SOUTHERLY WINDS TODAY
BUT WINDS VEER TO NORTHERLY THIS EVENING AS THE SURFACE HIGH BUILDS
AND WINDS INCREASE TO SMALL CRAFT IN OUTER WATERS ON SATURDAY. COULD
EVEN SEEM SOME GALE GUSTS IN THE NORTHERN OUTER WATERS BRIEFLY
SATURDAY EVENING. THIS NORTH WIND EVENT WILL BE VERY SHORT-LIVED AS
THERMAL TROUGH PUSHES OFF THE COAST AND WINDS BECOMING SOUTHERLY BY
MONDAY. HIGH PRESSURE IS EXPECTED TO RETURN BEHIND THIS BRINGING
NORTHERLY WINDS WEDNESDAY AND THURSDAY. THERE ARE SOME TIMING
DIFFERENCES IN THE MODELS BY LATE WEEK...HOWEVER WINDS LOOK TO
REMAIN BELOW 15 KT.

LONG PERIOD SWELL IS CURRENTLY AROUND 5 FEET 17 SECONDS AND IT IS
EXPECTED TO BUILD TO 8 TO 9 FT LATE TONIGHT AND EARLY SATURDAY
MORNING BEFORE GRADUALLY SUBSIDING. ANOTHER LONG PERIOD SWELL LOOKS
TO START BUILDING INTO THE WATERS ON SUNDAY. PERIODS WILL START OUT
AROUND 23 SECONDS...BUT WILL QUICKLY FALL BELOW 20 SECONDS SUNDAY
NIGHT. SHOALING WILL AGAIN BE AN ISSUE WITH THIS WAVE TRAIN. SNEAKER
WAVE THREAT LOOKS NEGLIGIBLE ON SUNDAY DUE TO WAVE INTERACTION WITH
SUBSIDING WIND WAVES AND RESIDUAL CURRENT WESTERLY SWELL BUT
INCREASES TO MODERATE MONDAY AS OTHER WAVE TRAINS CONTINUE TO
SUBSIDE. MKK/DEAN

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
