AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
312 AM PST SUN NOV 29 2009
.SYNOPSIS...HIGH PRESSURE WILL DOMINATE THE WEATHER PATTERN FOR
THE NEXT FEW DAYS...RESULTING IN CONTINUED SEASONABLY WARM
TEMPERATURES AND DRY CONDITIONS.
&&
.DISCUSSION...A RIDGE OF HIGH PRESSURE MOVING OVER THE WEST COAST
WILL BRING NORTHWEST CALIFORNIA ANOTHER SUNNY DAY WITH ABOVE
NORMAL TEMPERATURES, ESPECIALLY INLAND. HIGH TEMPERATURES WILL
MOSTLY BE IN THE 60S AND POSSIBLY A FEW 70S IN PARTS OF MENDOCINO
COUNTY. HOWEVER, AS THE RIDGE AXIS STARTS TO SHIFT TO OUR EAST
TONIGHT, WILL HAVE TO KEEP AN EYE JUST OFF THE COAST FOR STRATUS
AND FOG THAT MAY START TO DEVELOP. SOME OF THE MODELS ARE STILL
HINTING AT A WEAK DISTURBANCE MOVING OVER OUR AREA ON TUESDAY.
HOWEVER, THOSE MODELS DON'T HAVE MUCH MOISTURE WITH THIS
DISTURBANCE AND THIS COMBINED WITH ANOTHER RIDGE STARTING TO FORM
OVER THE WEST COAST AT THAT TIME WILL PROBABLY MEAN NORTHWEST
CALIFORNIA WILL JUST SEE SOME CLOUDS AND NO RAIN. THE NEW RIDGE IS
FORECAST TO REMAIN OVER THE WEST COAST FOR A FEW DAYS, CONTINUING
THE DRY WEATHER. SO LEFT THE LONG TERM FORECAST UNCHANGED. STROZ
&&
.AVIATION...MAINLY VFR FLYING TO PREVAIL TODAY AND TONIGHT...WITH
LOCAL MVFR/IFR CEILINGS AND VISIBILITIES POSSIBLE IN AREAS OF
VALLEY FOG AFTER 06Z MONDAY. THE FOG WILL LIKELY BE A BIT MORE
WIDESPREAD THAN THE PREVIOUS TWO NIGHTS...WITH SOME DEVELOPMENT
ALSO ALONG THE COAST. ATTM...EXPECTED COVERAGE NOT EXPECTED TO
SIGNIFICANTLY IMPACT OUR LOCAL TAF SITES. BETTWY
&&
.MARINE...EARLY MORNING BUOY OBSERVATIONS AND LAPS DATA INDICATE
WINDS ARE CONTINUING TO SUBSIDE ACROSS THE WATERS. A SOMEWHAT
CHAOTIC SEA STATE REMAINS ACROSS THE OUTER WATERS AND THIS WILL
PERSIST TODAY WITH SIGNIFICANT WINDS WAVES COMBINING WITH A
MODERATE NW SWELL. WINDS WILL HOLD STEADY STATE THROUGH THE DAY AS
HIGH PRESSURE SLOWLY MOVES INLAND INTO THE GREAT BASIN AND A WEAK
THERMAL TROUGH DEVELOPS ALONG THE COAST. AS THIS LOW INTENSIFIES
BRIEFLY THIS AFTERNOON...THE PRESSURE GRADIENT WILL ONCE AGAIN
TIGHTEN FOR A TIME...AND WILL RESULT IN LOCAL GALE FORCE GUSTS.
WINDS WILL DIMINISH MORE UNIFORMLY TONIGHT INTO MONDAY ALTHOUGH A
MODERATE NORTHWEST SWELL WILL CONTINUE TO IMPACT THE WATERS AND
CREATE A HAZARD TO MAINLY SMALL CRAFT. A HIGH PRESSURE RIDGE WILL
MOVE SOUTHEAST THROUGH THE WATERS MONDAY NIGHT INTO WEDNESDAY WITH
A SUBSIDING SWELL. A WEAKENING COLD FRONT MAY BRUSH THE WATERS
THURSDAY WITH ANOTHER LARGE SWELL TRAIN POSSIBLE LATE THURSDAY
INTO FRIDAY. BETTWY
