AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
1055 AM PDT SAT SEP 20 2008

.SYNOPSIS...WEAK HIGH PRESSURE WILL BUILD OVER NORTHERN CALIFORNIA
TODAY AND HOLD THROUGH MIDDAY SUNDAY BEFORE WEAKENING. INCREASING
CLOUDS ARE EXPECTED LATE SUNDAY NIGHT AS A WEAK UPPER LEVEL TROUGH
MOVES ACROSS THE REGION.

&&

.UPDATE...MORNING VISIBLE SATELLITE IMAGERY SHOWS FAIRLY EXTENSIVE
LOW CLOUDS OVER THE WESTERN TWO THIRDS OF THE CWA.  SKIES WILL
GRADUALLY BECOME PARTLY CLOUDY OVER THE INTERIOR THROUGH THE DAY
WITH SOME PARTIAL CLEARING EXPECTED FOR THE REDWOOD COAST AS WELL.
HAVE ISSUED AN UPDATE TO ACCOUNT FOR HIGHER CLOUD COVER AND
ASSOCIATED COOLER DAYTIME HIGHS FOR TODAY. KL

&&

.SHORT TERM...TODAY THROUGH MONDAY...THE GFS AND ECMWF MODELS ARE
IN GOOD AGREEMENT DURING THIS TIME PERIOD. OVERNIGHT...WIDESPREAD
SC CEILINGS AND AREAS OF VALLEY FOG WAS INDICATED BY SATELLITE
IMAGERY. AS THE TROUGH LIFTS TO THE NORTHEAST AND WEAK RIDGING
BUILDS OVER NORTHERN CALIFORNIA...THE CLOUDS WILL GRADUALLY BECOME
SCATTERED AND FOR INLAND LOCATIONS...THE SKIES WILL BECOME CLEAR.
THIS WILL MEAN A WARMING AND DRYING TREND FOR THE INTERIOR. THE
COAST WILL REMAIN UNDER THE INFLUENCE OF THE MARINE LAYER...AND
THE LOW CLOUDS AND PATCHY FOG WILL RETURN SATURDAY NIGHT INTO
SUNDAY MORNING. SUNDAY NIGHT A WEAK TROUGH WILL MOVE ACROSS THE
REGION. OTHER THAN AN INCREASE IN CLOUDS...NO WEATHER IS EXPECTED.
MONDAY A SLIGHTLY STRONGER RIDGE WILL BUILD AND MOVE ACROSS THE
REGION. KENNEDY

.LONG TERM...TUESDAY THROUGH FRIDAY...THE UPPER LEVEL RIDGE WILL
MOVE TO THE EAST AS AN UPPER LEVEL TROUGH APPROACHES THE PACIFIC
NORTHWEST. THE INLAND WARMING TREND WILL CONTINUE THROUGH TUESDAY.
THE MODELS DIFFER ON THE STRENGTH OF THIS TROUGH. THE ECMWF HAD A
DEEPER TROUGH AND EXTENDED THE PRECIPITATION FURTHER SOUTH THAN THE
GFS MODEL. AS A COMPROMISE...DID INCREASE THE POPS TO SLIGHT CHANCE
OF PRECIPITATION FOR WEDNESDAY AFTERNOON THROUGH WEDNESDAY NIGHT
NORTH OF KLAMATH. THE WEAK COLD FRONT ASSOCIATED WITH THIS SYSTEM
WILL BRING COOLER TEMPERATURES TO THE NORTHERN HALF OF THE CWA. THEN
FOR THURSDAY AND FRIDAY A WEAK RIDGE BUILD OVER THE REGION...
BRINGING A DRY PATTERN AND SEASON TEMPERATURES. THE ABSENCE OF A
STRONG OFFSHORE FLOW WILL CONTINUE THE USUAL REGIMEN OF LATE NIGHT
AND EARLY MORNING LOW CLOUDS ALONG THE COAST WITH PARTIAL CLEARING
EACH AFTERNOON.  KENNEDY

&&

.AVIATION...CIGS EARLY THIS MORNING CONTINUE TO REMAIN
VFR...GENERALLY BETWEEN 030 AND 050 ACROSS THE REGION. THOUGH NO
SITES HAVE REPORTED ANY LOWERED VSBYS YET...WITH YESTERDAYS LIGHT
PRECIP ACROSS THE REGION...MOST AREAS CAN EXPECT SOME BRIEF PATCHY
MVFR FOG AROUND SUNRISE...ESPECIALLY IN VALLEY LOCATIONS AND ALONG
THE COAST.

LIGHT AND VARIABLE WINDS THIS MORNING WILL SHIFT TO THE N AND NW BY
THE AFTERNOON HOURS AS HIGH PRESSURE STRENGTHENS OVER THE EAST
PACIFIC. WITH FLOW REMAINING GENERALLY LIGHT THROUGH THIS
AFTERNOON...ITS LIKELY THAT SCT-BKN 030-050 CIGS WILL CONTINUE
THROUGH THE DAY ESPECIALLY OVER COASTAL HILLS. ALM

&&

.MARINE...W-NW SWELL TRAIN BEHIND THE UPPER LOW PASSAGE CONTINUES TO
AFFECT THE REGION WITH SEAS RUNNING BETWEEN 4 TO 6 FT THIS MORNING.
WAVE RIDER BUOYS CONTINUE TO SHOW A SOUTHERLY SWELL OF 2 TO 3 FT
MOVING THROUGH THE WATERS. SEAS WILL PEAK THIS MORNING AT THEIR
CURRENT HEIGHTS AND GRADUALLY SUBSIDE THROUGH THE REMAINDER OF THE
DAY BACK DOWN TO 2 TO 3 FT...WITH SEAS REMAINING MIXED AS SOUTHERLY
SWELL CONTINUES.

N-NW WINDS WILL INCREASE THROUGH THE DAY AS HIGH PRESSURE BUILDS
OVER THE EAST PACIFIC. WINDS ARE EXPECTED TO INCREASE TO SCA LEVELS
OVER THE OUTER WATERS LATER ON SUNDAY AS STRONGER HIGH PRESSURE
BUILDS INTO THE PAC NW BEHIND ANOTHER WEAK FRONT. MODELS HAVE BEEN
INCONSISTENT WITH STRENGTH OF WINDS IN THE MON-WED TIME FRAME...BUT
SFC PRESSURE PATTERN CONTINUES TO LOOKS GOOD FOR HIGH END SCA
CONDITIONS AND HAVE CONTINUED TO INDICATED GALE FORCE GUSTS FOR THE
OUTER WATERS. SCA CONDITIONS ARE EXPECTED TO CONTINUE OVER THE OUTER
COASTAL WATERS THROUGH THE MIDDLE OF NEXT WEEK. ALM
