AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
451 AM PST MON DEC 8 2014

.SYNOPSIS...A SERIES OF DISTURBANCES ALONG WITH A MOIST SOUTHWESTERLY
FLOW WILL MAINTAIN A CHANCE SHOWERS THROUGH TUESDAY. A STRONG STORM
SYSTEM WILL APPROACH ON WEDNESDAY...BRINGING HIGH WINDS AND BOUTS
OF HEAVY RAIN WEDNESDAY THROUGH THURSDAY.

&&

.DISCUSSION...RADAR SHOWED SCATTERED SHOWERS MOVING ONSHORE SOUTH
OF CAPE MENDOCINO EARLY THIS MORNING. SOME OF THIS SHOWER ACTIVITY
HAS BEEN SPREADING NORTHWARD. THE MOIST SOUTHWESTERLY FLOW AND
PERIODIC SHORTWAVES WILL CONTINUE TO MOVE OVER THE AREA THROUGH
TUE. THE GFS...NAM12 AND ECMWF CONTINUE TO BE ALL OVER THE PLACE
ON WHERE AND WHEN IT WILL RAIN. CONFIDENCE IS NOT HIGH ENOUGH AT
THIS POINT TO GO WITH VERY HIGH PRECIP CHANCES. RAIN AMOUNTS DO
NOT APPEAR TO BE VERY MUCH...MOSTLY A FEW HUNDREDTHS TO PERHAPS
ISOLATED AMOUNTS AROUND ONE TENTH. IT WILL CONTINUE TO BE MILD FOR
THE NEXT COUPLE OF DAYS AS SOUTHERLY FLOW PERSISTS AND HUMIDITIES
REMAIN HIGH. WE SHOULD SEE DRYING AS WELL AS REDUCED PRECIP
CHANCES TUE NIGHT AS ROBUST SOUTHEASTERLY FLOW DEVELOPS IN
ADVANCE OF WET AND POTENT FRONTAL SYSTEM.

THE PRECIP FORECAST WILL BECOME FAIRLY STRAIGHT FORWARD LATTER IN
THE WEEK AS WIDESPREAD MODERATE TO HEAVY RAIN DEVELOPS AND
EVERYONE GETS RAIN FOR A PROLONGED PERIOD. A STRONG FRONTAL SYSTEM
WILL APPROACH ON WED...BRINGING STRONG SOUTHERLY WINDS TO THE
COASTAL RANGES AND WATERS. LOW LYING AREAS NEAR MEAN SEA LEVEL
WILL SEE BLUSTERY WINDS AS WELL. THE HIGHER ELEVATIONS WILL NO
DOUBT SEE GUSTS UP TO 60-70 MPH...PERHAPS HIGHER IN FAVORED WIND
PRONE AREAS OF THE MOUNTAINS. UNTIL HIGHER RESOLUTION AND RELIABLE
DATA BECOMES AVAILABLE...STRONG WINDS UP TO 60 MPH NEAR MEAN SEA
LEVEL REMAINS VERY SKETCHY.

ALSO...THE GFS AND ECMWF WERE NOT IN REAL GOOD SYNC ON THE TIMING
OF THE RAIN. GFS WAS MUCH SLOWER AND HAS MOST OF THE FORECAST AREA
DRY ON WED...WHILE THE ECMWF HAS RAIN OVERSPREADING THE ENTIRE
AREA BY WED AFTERNOON. THE TIMING SHOULD NOT MATTER THAT MUCH AS
IT WILL RAIN...JUST A MATTER OF WHETHER IT'S BEFORE 4PM WED OR
AFTER. WE ARE EXPECTING HEAVY RAIN BY WEDNESDAY NIGHT. THE
HEAVY RAIN MAY CONTINUE THU INTO THU NIGHT ACROSS MENDOCINO
COUNTY AS THE MOISTURE PLUME SLOWLY MOVES SOUTHWARD. THERE WILL BE
FLOODING CONCERNS BOTH ON MAIN STEM RIVERS AS WELL AS LOCALIZED
FLOODING OF ROADWAYS...CREEKS AND OTHER FLOOD PRONE LOW LYING
AREAS WITH POOR DRAINAGE. THERE ARE UNKNOWN VARIABLES HERE LIKE
HOW FAST THE HEAVY RAIN WILL LAST AND IF THE FRONT STALLS OR SLOWS
DOWN. THE ECMWF HAS THE FRONT STALLING OVER MENOCINO COUNTY. THE
GFS TAKES THE HEAVY RAIN SOUTHWARD FASTER. THE SITUATION WILL
NEED TO BE CLOSELY MONITORED AS THIS EVENT UNFOLDS. STAY TUNED.

RAIN WILL DECREASE FRIDAY INTO SATURDAY AS A COLD AIR MASS
SETTLES OVER THE AREA. SNOW LEVELS WILL FALL TO 4000 TO 5000 FEET
AS THE PRECIP DIMINISHES TO ISOLATED OR SCATTERED LIGHT SHOWERS.
NO SIGNIFICANT ACCUMULATIONS ARE ANTICIPATED. EVEN THOUGH THE AIR
MASS WILL BE COOLER...THERE WILL STILL BE LOTS OF LOW CLOUDS OR
FOG TO BLANKET THE VALLEYS OVERNIGHT.

BOTH THE GFS AND ECMWF INDICATE THAT A RIDGE WILL BUILD IN BEHIND
THE DEPARTING TROUGH THIS WEEKEND ALLOWING FOR A FEW DAYS OF DRY
WEATHER. THE GFS AND ECMWF DO INDICATE ANOTHER SYSTEM APPROACHING
SUNDAY NIGHT INTO MONDAY FOR POSSIBLY MORE RAIN. THIS REMAINS
VERY IFFY AS THE ECMWF HAS BEEN HINTING AT A "CUT-OFF LOW"
DEVELOPING WHICH WILL SLOW DOWN THE EASTWARD PROGRESSION.

&&

.AVIATION...VFR IS EXPECTED FOR COASTAL AREAS TODAY AS A WEAK
BOUNDARY LIFTS THROUGH. BRIEF PERIODS OF MVFR ARE POSSIBLE DURING
TIMES OF LIGHT RAIN. UKI AND OTHER INTERIOR LOCATIONS WILL CONTINUE
TO BE IFR/MVFR MUCH OF THE DAY AS BANDS OF RAIN PASS BY. BFG

&&

.MARINE...SOUTHERLY WINDS WILL REMAIN DOMINANT OVER THE COASTAL
WATERS THROUGH MIDWEEK AS A SERIES OF FRONTS CROSSES THE REGION.
TODAY WILL BE AN IN BETWEEN DAY, WITH WINDS IN THE MODERATE TO FRESH
RANGE AND STEEP SOUTHERLY WAVES COMING DOWN A TOUCH. HOWEVER, WITH
AN ACTIVE PATTERN ACROSS THE NORTH PACIFIC A LARGE SWELL WILL BUILD
INTO THE COASTAL WATERS BY THIS AFTERNOON. HEIGHTS WILL REACH TO
AROUND 13 FT AT 15 SECONDS. AS THIS SWELL SUBSIDES TUESDAY INTO
WEDNESDAY, IT WILL BE OVERRUN WITH ANOTHER BUILDING SWELL ON TUESDAY
AFTERNOON. THIS SWELL IS FORECAST TO PEAK AROUND 17 FT AT 16
SECONDS. MODELS HAVE BEEN CONSISTENT WITH THIS SWELL DEVELOPING AND
LINGERING THROUGH THE WEEK, SO CONFIDENCE IS INCREASING AS TO IT
ACTUALLY ARRIVING.

DESPITE SWELL BUILDING FOR THE WEEK, THE MAIN EVENT WILL BE MIDWEEK
AS A STRONG COLD FRONT APPROACHES THE WATERS. THIS WILL CAUSE
SOUTHERLY WINDS TO INCREASE RAPIDLY. THE PARENT LOW OF THIS FRONT IS
FORECAST TO DEEPEN AS IT APPROACHES THE OREGON COAST, WHICH WILL
CAUSE AN INTENSIFICATION OF THE SURFACE PRESSURE GRADIENT AND THUS
INCREASING WINDS. MODELS ARE IN DECENT AGREEMENT WITH THE LOW
HEADING TOWARD COASTAL OREGON AND DEPICTING THE SURFACE WINDS WELL
INTO THE GALE RANGE. THE QUESTION AT THIS POINT IS WHETHER STORM
CONDITIONS WILL BE ATTAINED? THIS IS AN OUTSIDE SHOT AT THIS TIME,
BUT ALL IT TAKES IS A SLIGHT SHIFT SOUTHWARD IN THE LOW TO BRING THE
STRONG PART TOWARD NW CAL. ON THE OTHER HAND, A SHIFT NORTHWARD
WOULD CAUSE US TO BECOME MORE MARGINAL GALE. WITH A TOUCH OF
UNCERTAINTY LEFT IN THE SPECIFICS, BUT HIGH CONFIDENCE IN THE
PATTERN, HAVE HOISTED A GALE WATCH FOR ALL THE COASTAL WATERS DURING
THE MIDDLE PART OF THE WEEK. WE WILL REFINE TIMING AND STRENGTH AS
WE GET CLOSER TO THE EVENT. REGARDLESS, IT WILL BE A STRONG STORM.
IF YOU HAVE WEATHER SENSITIVE INTERESTS IN THE COASTAL WATERS THIS
WEEK, TAKE ACTION NOW IN PREPARATION OF THE COMING STORM. BFG
