AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
423 AM PST WED DEC 18 2013

.SYNOPSIS...A COLD FRONT WILL BRING COOLER TEMPERATURES TODAY
ALONG WITH SOME SPRINKLES OR LIGHT SHOWERS NORTH OF MENDOCINO
COUNTY. TONIGHT AND THURSDAY WILL BE WINDY AND COOLER AS HIGH
PRESSURE RETURNS. ANOTHER WEAK STORM SYSTEM WILL BRING A CHANCE OF
LIGHT RAIN NORTH OF CAPE MENDOCINO FOR SATURDAY.

&&

.DISCUSSION...COASTAL LOW CLOUDS AND FOG DEVELOPED DURING TUE
EVENING...AND THIS IS STILL EVIDENT ON 11-3.9 MICRON SATELLITE
IMAGERY. THICK MID AND HIGH CLOUDINESS CONTINUES SPREAD SE AHEAD
OF AN APPROACHING UPPER TROF AND ASSOCIATED SURFACE FRONT. LIGHT
PRECIP WILL REACH DEL NORTE COUNTY DURING THE AFTERNOON...WITH
PRECIP GRADUALLY SPREADING S INTO N HUMBOLDT. RAINFALL AMOUNTS
WILL BE LIGHT WITH THIS SYSTEM WITH TOTALS OF AROUND A TENTH OF
AN INCH N OF CAPE MENDO THRU TONIGHT. A FEW SPOTS IN THE HIGHER
TERRAIN OF DEL NORTE COUNTY MAY BE ABLE TO SQUEEZE OUT CLOSER TO
1/4. TEMPERATURES WILL BE ON THE DECLINE THIS AFTERNOON AND
ESPECIALLY TONIGHT. SNOW LEVELS WILL DROP BELOW 2500 FT BY LATE
TONIGHT...BUT MOST OF THE PRECIP WILL BE ABOUT OVER BY THIS TIME.

WINDS WILL RAMP UP LATE THIS AFTERNOON AND TONIGHT...WITH GUSTS TO
40 MPH ALONG THE COAST AND OVER 30 MPH INLAND OVERNIGHT AND THU
MORNING. WINDS AT HIGHER ELEVATIONS WILL BE STRONGER...
PARTICULARLY OVER COASTAL HIGHLANDS AND INLAND RIDGETOPS. FORECAST
WIND SPEEDS LOOK TO BE AT LEAST 5 MPH LOWER THAN ADVISORY
CRITERIA...BUT LATER SHIFTS WILL NEED TO CLOSELY MONITOR LATEST
MODEL TRENDS. FOR NOW...HAVE HIGHLIGHTED WINDS IN ZONE FORECAST
PRODUCTS AND THE HAZARDOUS WX OUTLOOK. WILL ALSO ADDRESS IN SOCIAL
MEDIA.

A WEAK DISTURBANCE WILL MOVE S ALONG THE PAC NW COAST FRI NIGHT
INTO SAT WITH ANOTHER SHOT AT VERY LIGHT PRECIP N OF CAPE MENDO.
THE REMAINDER OF THE FORECAST PERIOD IS EXPECTED TO BE GENERALLY
DRY. MODELS DIVERGE QUITE A BIT BY EARLY NEXT WEEK. HAVE LEANED
BELOW CLIMO DUE TO MOSTLY DRY GFS ENSEMBLE MEMBERS DURING THIS
TIME PERIOD. SEASONABLE NIGHTTIME LOWS AND MILD TO WARM DAYTIME
HIGHS ARE EXPECTED OVER INLAND LOCALES FROM THE WEEKEND INTO THE
MIDDLE OF NEXT WEEK. TEMPERATURES ALONG THE COAST WILL REMAIN NEAR
NORMAL DURING THIS PERIOD.

&&

.AVIATION...SHALLOW MARINE DECK HAS BEEN REDUCING VSBY AT CEC AND
ACV EARLY THIS MORNING. VSBY HAS BEEN DOWN TO 1/4SM AT ACV WHILE
OFFSHORE FLOW AT CEC HAS BEEN KEEPING THE FOG AT BAY. A LOW PRESSURE
TROUGH WILL DROP DOWN FROM THE NORTH TODAY INCREASING THE ONSHORE
FLOW. LAYER SHOULD DEEPEN AND CIGS WILL LIKELY RISE UP THROUGH THE
DAY AS MIXING INCREASING. STRONGER COOLING ALOFT AND BRISK NORTHERLY
FLOW WILL LIFT UP THE LOW CLOUD DECK EVEN MORE TONIGHT AND
EVENTUALLY SCOUR IT OUT BY EARLY THU MORNING AS THE LOW PRESSURE
TROUGH PASSES SOUTHEAST OF THE COAST.

&&

.MARINE...NORTHERLY WINDS AND SHORT PERIOD SEAS WILL INCREASE LATE
TODAY AND THEN RAMP UP SIGNIFICANTLY TONIGHT AND THU AS A LOW PRES
TROUGH DROPS DOWN FROM THE NORTH. I CONTINUED THE GALE WARNINGS IN
THE OUTER WATERS AND HOISTED FLAGS FOR STORM FORCE WINDS IN THE
SOUTHERN OUTER WATERS. BOTH THE GFS AND NAM12 MODELS INDICATE
BOUNDARY LAYER WINDS HITTING 50KT DURING AND RIGHT AFTER TROUGH
PASSAGE LATE TONIGHT INTO EARLY THU. EXPANDED THE GALE WATCH INTO
THE NORTHERN INNER WATERS AS WELL. GRADIENTS DO NOT LOOK QUITE
AS STRONG IN THE NORTHERN WATERS. HOWEVER THE STRONG NORTHERLY
WINDS ALOFT SHOULD TRANSPORT DOWN TO MEAN SEA LEVEL AND PRODUCE
GALE GUSTS. PLUS SEAS WILL BE FLIRTING WITH HAZARDOUS SEAS WARNING
LEVELS...14 FT AT 10 SECONDS TONIGHT. MODELS REMAIN CONSISTENT
WITH GALES CONTINUING IN THE OUTER WATERS ON THU...BUT DIMINISHING
JUST A TAD IN THE AFTERNOON AS LOW PRESSURE TROUGH MOVES SE OF THE
AREA. THE GFS...ECMWF AND NAM12 HAVE WINDS FALLING OFF THU NIGHT AND
THEN MORE SUBSTANTIALLY ON FRI AS ANOTHER TROUGH POUNCES DOWN ON THE
RIDGE. MAIN STORY COME FRIDAY WILL BE THE ARRIVAL OF 1 TO 2 FOOT 20+
SECOND WESTERLY SWELL. THE SWELL WILL BUILD OVER THE WEEKEND. THUS
EXPECT SHOALING HAZARDS AND BEACH HAZARDS FROM THIS LONG PERIOD
SWELL FRI AND OVER THE WEEKEND.
