AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
322 AM PST MON NOV 30 2009

.SYNOPSIS...HIGH PRESSURE AND OFFSHORE WINDS WILL CONTINUE TO
DOMINATE THE WEATHER PATTERN FOR THE NEXT COUPLE OF
DAYS...RESULTING IN UNSEASONABLY WARM INLAND TEMPERATURES AND DRY
CONDITIONS.

&&

.DISCUSSION...THE RUNNING FORECAST REMAINS ON TRACK. TEMPERATURES
THIS MORNING ARE A FEW DEGREES WARMER THAN AT THIS TIME YESTERDAY,
SO ANY FROST THAT FORMS WILL ONLY BE PATCHY IN NATURE.
TEMPERATURES WILL AGAIN RISE QUICKLY AFTER SUNRISE DUE TO HIGH
PRESSURE SITTING OVER THE REGION. SATELLITE IMAGERY SHOWS STRATUS
OFF THE OREGON COAST AND MOVING SOUTH ALONG WITH HIGH CLOUDS
ASSOCIATED WITH A DISTANT FRONT APPROACHING THE WEST COAST. EXPECT
THE STRATUS TO STAY OFFSHORE TODAY AND MOST OF THE HIGH CLOUDS TO
DISSIPATE/MOVE TO THE NORTH OF THE AREA ALONG WITH THE FRONT. SO
ANOTHER DRY DAY FOR NORTHWEST CALIFORNIA WITH HIGH CLOUDS AND
ABOVE NORMAL INLAND TEMPERATURES. SOME OF THE MODELS STILL SHOW A
WEAK DISTURBANCE MOVING OVER THE AREA LATE TUESDAY. HOWEVER, NO
RAIN IS EXPECTED, ESPECIALLY BECAUSE THIS DISTURBANCE WILL BE
MOVING THROUGH WHEN ANOTHER RIDGE IS BUILDING OVER THE REGION. THE
RIDGE IS FORECAST TO REMAIN OVER THE WEST COAST UNTIL THE WEEKEND,
CONTINUING THE DRY WEATHER AND ABOVE NORMAL INLAND TEMPERATURES.
MODELS ARE STARTING TO INDICATE A PATTERN CHANGE OVER THE WEEKEND.
BUMPED UP POPS ABOVE CLIMO FOR SUNDAY, BUT EXPECT THEM TO NEED TO
BE RAISED FURTHER IF THE MODELS COME INTO BETTER AGREEMENT WITH
THE TIMING AND STRENGTH OF THE PATTERN CHANGE. STROZ

&&

.AVIATION...MAINLY VFR FLYING TO PREVAIL TODAY AND TONIGHT...WITH
PERIODS OF MVFR IN LIGHT FOG AND HAZE...MAINLY ALONG THE COAST AND
ALSO ACROSS THE INTERIOR VALLEYS. FOG MAY BECOME WIDESPREAD AND A
BIT MORE DENSE LATE TONIGHT...BUT GUIDANCE SEEMS TO SUGGEST ANY
ORGANIZED AREAS OF FOG ARE MORE LIKELY TO STAY OFFSHORE. BETTWY

&&

.MARINE...BUOY OBSERVATIONS INDICATE LIGHT TO MODERATE WINDS
ACROSS THE WATERS EARLY THIS MORNING...ALTHOUGH A MODERATE LONG
PERIOD NORTHWEST SWELL CONTINUES TO TRAVERSE THROUGH THE WATERS. A
THERMAL TROUGH WILL ONCE AGAIN FORM ALONG THE COAST THIS
AFTERNOON...BUT WITH A WEAKER PRESSURE GRADIENT IN PLACE...ANY
INCREASE IN WINDS WILL BE SLIGHT AND SHORT-LIVED. OTHERWISE...A
HIGH PRESSURE RIDGE WILL MOVE SOUTHEAST THROUGH THE WATERS LATE
TONIGHT INTO WEDNESDAY WITH A SUBSIDING SWELL. A WEAKENING COLD
FRONT MAY BRUSH THE WATERS LATE THURSDAY INTO FRIDAY...WITH
ANOTHER LARGE SWELL TRAIN POSSIBLE. BETTWY
