AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
354 AM PST FRI NOV 28 2008

.SYNOPSIS...STRONG HIGH PRESSURE BUILDING OVER THE WEST COAST
WILL BRING UNSEASONABLY WARM TEMPERATURES...MOSTLY CLEAR
SKIES...AND DRY WEATHER TO THE REGION THROUGH THE WEEKEND. NIGHT
AND MORNING FOG CAN BE EXPECTED IN VALLEY LOCATIONS THROUGH THE
PERIOD.

&&

.SHORT TERM...TODAY THROUGH SUNDAY...WATER VAPOR IMAGERY SHOWS
THAT THE STRONG UPPER LEVEL RIDGE HAS ALREADY BEGUN TO BUILD INTO
THE WEST COAST AS THE UPPER LEVEL LOW THAT HAS BEEN PLAGUING
SOUTHERN CALIFORNIA AND THE DESERT SOUTHWEST LIFTS OUT INTO THE
GREAT PLAINS. THE AREA WILL SEE NORTHERLY FLOW PICKING UP TODAY
AS SURFACE HIGH PRESSURE BEGINS TO BUILD INTO THE PAC NW AND GREAT
BASIN. INCREASING HEIGHTS AND WIND SHOULD HELP SCOUR OUT LOW
CLOUDS AND FOG FOR MOST AREAS BY LATE MORNING...THOUGH FOG MAY
LINGER LONGER IN WELL SHELTERED INTERIOR VALLEYS. AFTER THE FOG
BURN OFF...MOSTLY CLEAR SKIES ARE EXPECTED THOUGH WE WILL CONTINUE
TO SEE PASSING HIGH CLOUDINESS AS MOISTURE STREAMS OVER THE TOP OF
THE UPPER RIDGE.

RADIATIONAL FOG AND LOW CLOUDS WILL CONTINUE TO FORM ACROSS THE
INTERIOR RIVER VALLEYS LATE NIGHTS/EARLY MORNINGS...BUT THE
COVERAGE AND PERSISTENCE WILL BE LESS. WITH THE WARMING ALOFT AND
OFFSHORE FLOW...MAX TEMPS WILL INCREASE EACH DAY. UNDER A STRONG
INVERSION...VALLEYS WITH POOR SOLAR INSOLATION AND MIXING WILL
STRUGGLE TO REACH THE LOWER 60S...WHILE THE RIDGES AND SOUTH
FACING SLOPES BASK IN SUNSHINE...WITH HIGHS TOPPING OUT IN THE MID
70S. SOLUTIONS INDICATE THE WARMEST DAY TO BE ON SATURDAY. WARM
AIR ALOFT WILL HOLD THROUGH SUNDAY...AND THE DRY/CLEAR WEATHER
WILL CONTINUE AFTER A CRISP AND FOGGY MORNING ON SUNDAY.

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY...UPPER RIDGE AXIS
SHIFTING TO THE EAST BY SUNDAY NIGHT WILL MEAN COOLER TEMPERATURES
AND THE RETURN OF COASTAL FOG/STRATUS FOR MONDAY AS OFFSHORE FLOW
WEAKENS. GUIDANCE SEEMS TO BE IN AGREEMENT ON A POTENT UPPER LOW
OR SHORTWAVE WILL SCOOTING ACROSS BC AND WASHINGTON MONDAY
AFTERNOON. MODELS WANT TO BRING SOME PRECIP ACROSS THE AREA WITH
THIS FEATURE...AND HAVE PUT SOME SLIGHT CHANCE POPS ACROSS FAR
NORTHERN DEL NORTE TO INDICATE THIS...BUT THINK THAT MODELS MIGHT
BE OVERDONE WITH ITS EFFECT ON OUR REGION AS WE WILL CONTINUE TO
BE UNDER THE INFLUENCE TO THE DEPARTING RIDGE. BY WEDNESDAY...ALL
MEDIUM RANGE MODELS WERE INDICATING A RIDGE DEVELOPING OFFSHORE
WITH A SHORTWAVE MOVING DOWN THE COAST...CUTTING OFF WEST OF
SOUTHERN CA BY THURSDAY. WITH THIS SOLUTION SOME SLIGHT CHANCE OF
SHOWERS WOULD OCCUR BUT THERE IS NOT VERY MUCH CONFIDENCE IN THIS
SOLUTION AS THE RUN TO RUN CONSISTENCY OF THE MODELS WERE NOT VERY
GOOD. ALM

&&

.AVIATION...SURFACE OBSERVATIONS SHOW COASTAL SITES MAINLY VFR WHILE
INLAND SITES ARE MVFR/IFR FOR CEILINGS. SATELLITE IMAGERY SHOWS SOME
MID TO UPPER LEVEL CLOUDS MOVING IN OVER THE AREA...WHICH HAS HELPED
TO CLEAR OUT COASTAL LOCATIONS. BELIEVE THESE HIGH CLOUDS WILL HELP
TO KEEP COASTAL LOCATIONS VFR TIL SUNRISE AND THEN THEY SHOULD STAY
VFR THROUGHOUT THE DAY. INLAND LOCATIONS WILL BECOME VFR AFTER
SUNRISE. MS

&&

.MARINE...SWELL FROM A STORM MOVING ACROSS THE NORTH PACIFIC WILL
ARRIVE IN THE NORTHERN CA WATERS THIS MORNING. THE SWELL IS EXPECTED
TO PEAK AT 10 TO 12 FT AT 16 SECONDS THIS AFTERNOON AND THEN
SUBSIDE THROUGH SATURDAY. WINDS WILL INCREASE THIS EVENING AS HIGH
PRESSURE BUILDS INTO THE REGION. WINDS WILL BE STRONG ENOUGH OVER
THE SOUTHERN OUTER WATERS THAT A SCA HAS BEEN POSTED FOR THAT ZONE
FROM TONIGHT THROUGH SATURDAY MORNING. A STRONG STORM CURRENTLY
MOVING ACROSS THE GULF OF ALASKA WILL GENERATE A LARGE WEST
NORTHWEST SWELL THAT WILL SPREAD INTO THE NORTHERN CA WATERS ON
SATURDAY. SWAN AND ENP CONTINUE TO SHOW A SWELL APPROACHING 15
FT...BUT HAVE ONCE AGAIN CUT THAT DOWN BY A FOOT DUE TO THE MODELS
OVER-FORECASTING SWELL HEIGHTS SO FAR THIS FALL.
REGARDLESS...BREAKING WAVES OF 18 TO 20 FT WILL BE POSSIBLE ALONG
WEST AND NORTHWEST FACING BEACHES SATURDAY AFTERNOON INTO SUNDAY.
SEAS WILL REACH THEIR MAXIMUM HEIGHTS SUNDAY MORNING BEFORE
SUBSIDING INTO EARLY NEXT WEEK. MS
