NWS Eureka, CA wrote its last area forecast discussion before this gale warning went out at Nov 21, 2:03 PM PST, 8 hours 33 minutes earlier.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
203 PM PST SAT NOV 21 2009

.SYNOPSIS...A STORM SYSTEM WILL BRING MORE RAIN AND HIGHER ELEVATION
SNOW TO NORTHWEST CALIFORNIA TONIGHT INTO SUNDAY. WARMER AND DRY
WEATHER IS EXPECTED FOR EARLY NEXT WEEK. ANOTHER CHANCE OF RAIN IS
EXPECTED FOR LATE NEXT WEEK.

&&

.DISCUSSION...SKIES CLEARED RAPIDLY EARLY TODAY ACROSS NORTHWEST
CALIFORNIA...AS A STABLE AIR MASS MOVED IN BEHIND THE DEPARTING
COLD FRONT. VISIBLE SAT IMAGES SHOW A CLOUD SHIELD MOVING TOWARD THE
COAST...CURRENTLY BEGINNING TO FILTER OVER THE REDWOOD COAST. THIS
WILL BRING ADDITION RAIN TO MOST OF THE CWA...WITH SNOW AT THE
HIGHER ELEVATIONS. CURRENTLY EXPECT SNOW LEVEL TO BE NEAR 5000
FT...ALTHOUGH SOME COLD AIR POCKETS IN THE TRINITY VALLEYS MAY ALLOW
A LITTLE SNOW TO MIX DOWN IN CERTAIN LOCATIONS. THE LIKELY SPOTS ARE
SHELTERED VALLEYS IN EASTERN HUMBOLDT AND WESTERN TRINITY COUNTIES.
RAIN WILL BEGIN LATER THIS AFTERNOON/EVENING...PERHAPS AS EARLY AS
AROUND 00Z...ACCOMPANIED BY THE AFOREMENTIONED SNOWFALL. THE EVENT
WILL CONTINUE THROUGH LATE MORNING SUNDAY. THINGS WILL TAPER OFF
FAIRLY QUICKLY SUNDAY AFTERNOON AS UPPER RIDGING BUILDS INTO THE
EASTERN PACIFIC.

THE UPPER RIDGE WILL MOVE EAST RAPIDLY SUNDAY NIGHT PER GFS
FORECAST. THE FIVE WAVE PATTERN SHOWS A VERY LOW AMPLITUDE RIDGE
OVER THE WEST COAST WITH PROGRESSIVE FLOW OVER THE PACIFIC. UNDER
THIS SCENARIO THE RIDGE WILL WEAKEN AS A SHORT WAVE TROUGH SWINGS
ACROSS VANCOUVER ISLAND ON MONDAY. THIS MAY BRING SOME INCREASED
CLOUDINESS TO THE FAR NORTHERN CWA BUT LITTLE CHANCE OF RAIN. UPPER
RIDGING WILL THEN RETURN FOR TUESDAY AND WEDNESDAY. THIS WILL
PROVIDE A COUPLE DAYS OF WARMER AND DRYER WEATHER WITH 500 MB
HEIGHTS RISING TO NEAR 580. ANOTHER TROUGH AND ASSOCIATED FRONTAL
BAND WILL APPROACH THE PAC NW COAST EARLY THURSDAY. THE ECMWF IS
SLIGHTLY FASTER THAN GFS AND CANADIAN...AND DEVELOPS A DEEPER TROUGH
AS IT MAKES LANDFALL EARLY FRIDAY. THIS TIME PERIOD IS WHEN MODEL
DIFFERENCES START TO BECOME SIGNIFICANT. FOR THE SAKE OF CONSISTENCY
HAVE MAINTAINED CHANCE POPS ACROSS THE AREA FOR THURSDAY AND
FRIDAY...AND INDICATED AN IMPROVING TREND FOR SATURDAY. THE AIR MASS
APPEARS WARM ENOUGH TO SUPPORT SNOW LEVELS NEAR 7000 FT...SO THAT
WINTER DRIVING CONDITIONS ARE NOT EXPECTED FOR HOLIDAY TRAVEL. CMC

&&

.MARINE...SOUTHERLY WINDS WILL INCREASE THIS EVENING AHEAD OF AN
APPROACHING COLD FRONT. THE FRONT WILL PUSH EAST THROUGH THE WATERS
LATE TONIGHT AND SUNDAY MORNING...WITH WINDS SWITCHING TO
NORTHWESTERLY. ALONG WITH A PERSISTENT WESTERLY SWELL...HAZARDOUS
CONDITIONS FOR SMALL CRAFT WILL CONTINUE THROUGH TOMORROW NIGHT. A
LONGER PERIOD NORTHWEST SWELL WILL AFFECT THE WATERS BY MID
WEEK...ALTHOUGH WINDS ARE EXPECTED TO BE RELATIVELY LIGHT NEXT WEEK.
HENRY
&&

.AVIATION...A COLD FRONT WILL PUSH EAST THROUGH THE NORTH COAST
REGION LATE TONIGHT AND SUNDAY MORNING. WHILE NOT QUITE AS WET AS
THE LAST SYSTEM...MVFR WITH AREAS OF IFR CONDITIONS ARE EXPECTED
WITH PREVAILING RAIN SHOWERS...MAINLY STARTING BTW 03 AND 06Z ALONG
THE COAST...AND 05 AND 08Z INLAND TOWARD KUKI. BEHIND THE
FRONT...MVFR CIGS ARE EXPECTED TO PREVAIL THROUGH THE DAY SUNDAY.

NORTHWEST CALIFORNIA COASTAL WATERS...
