AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
257 PM PDT FRI SEP 30 2011

.SYNOPSIS...A WEAK STORM SYSTEM WILL BRING SCATTERED SHOWERS TO NORTHWEST
CALIFORNIA ON SATURDAY. A BREAK IN THE WEATHER IS EXPECTED MOST OF
SUNDAY BEFORE A MORE POTENT FRONT ARRIVES BY MONDAY MORNING. WET
AND COOL WEATHER WILL THEN CONTINUE THROUGH AT LEAST WEDNESDAY.

&&

.DISCUSSION...ANY OUTDOOR PLANS? THIS WEEKEND WILL BE YOUR
BEST...AND LAST CHANCE FOR DRY WEATHER BEFORE THE FIRST MAJOR RAIN
MAKER OF THE SEASON ARRIVES. A LARGE LOW SPINNING JUST SOUTH OF
THE ALASKA PENINSULA WILL BE THE MAJOR PLAYER IN DETERMINING OUR
WEATHER FOR NEXT WEEK. BEFORE THAT TIME...A WEAK LOW SPINNING A
COUPLE HUNDRED MILES OFF THE MENDOCINO COAST WILL SLOWLY LIFT NE
OVERNIGHT AS A WEAK SHORTWAVE PASSES TO OUR NORTH. WITH A FAIRLY
DEEP MARINE LAYER ALREADY IN PLACE...AND INCREASED LIFT FROM THE
SHORTWAVE PASSAGE...PATCHY DRIZZLE OR A LITTLE LIGHT RAIN IS
POSSIBLE OVERNIGHT ALONG THE COAST. DURING THE DAY ON SAT AS THE
SHORTWAVE AND ASSOCIATED FRONT PASSES BY...A FEW SHOWERS ARE
POSSIBLE...MAINLY NORTH OF CAPE MENDOCINO. HIGH PRESSURE BRIEFLY
TAKES HOLD SAT NIGHT AND SUN AHEAD OF A MORE POTENT COLD FRONT.

THE COLD FRONTAL PASSAGE IS EXPECTED EARLY MON MORNING WITH
WIDESPREAD RAIN AND GUSTY WINDS ACROSS NW CA. RAINFALL TOTALS ARE
EXPECTED TO RANGE FROM 0.25 TO 0.75 INCHES. AN EVEN STRONGER FRONT
ARRIVES TUE AFTN WITH ANOTHER SUBSTANTIAL SLUG OF MOISTURE AND
STRONG WINDS. PWATS ASSOCIATED WITH THIS SECOND FRONT ARE FORECASTED
TO BE 3 STANDARD DEVIATIONS ABOVE NORMAL (AROUND 1.25
INCHES)...WITH THE POSSIBLE ENTRAINMENT OF SOME TROPICAL MOISTURE.
AFTER THE INITIAL FRONT PASSES BY...THE UPPER LEVEL TROUGH STILL
LINGERS TO THE WEST. THIS MEANS THAT SHOWERS WILL CONTINUE BEFORE
THE TROUGH AXIS AND ASSOCIATED COLD CORE MOVES OVERHEAD LATE WED.
THE COLDEST AIR OF THE SEASON WILL ARRIVE BEHIND THIS FRONT...WITH
SNOW LEVELS POSSIBLY FALLING AS LOW AS 5500 FT ON WED. RAINFALL
TOTALS WITH THIS SECOND SYSTEM ARE STILL HIGHLY QUESTIONABLE...BUT
EARLY FORECASTS FROM HPC INDICATE THE POSSIBILITY OF 2-4 INCHES.
STAY TUNED FOR UPDATES ON THIS DEVELOPING SITUATION AS FORECASTS
WILL BE FINE TUNED OVER THE WEEKEND. JCA

&&

.AVIATION...SATELLITE IMAGERY SHOWED STRATOCUMULUS TYPE CLOUDS
OVER THE WATERS AND ALONG THE COAST THIS AFTERNOON. MVFR CLOUD
LAYER FROM 1500 TO 2500 FEET SHOULD SPREAD INLAND AGAIN TONIGHT AS A
WEAK LOW APPROACHES FROM THE SW. EXPECT CLOUDS TO PUSH INTO KUKI
AGAIN...PERHAPS AS EARLY AS 11 PM THIS EVENING. NOT TOO CONFIDENT
CEILINGS OR VSBYS WILL DROP TO IFR AT KACV OR KCEC AGAIN TONIGHT AS
THE SOUTHERLY FLOW ALOFT INCREASES AND THE AIR MASS COOLS SLIGHTLY.
THEREFORE...TIMING OF IFR CONDS HAS BEEN ADJUSTED TO EARLY SAT.

&&

.MARINE...A WK FRONT WILL APPCH THE WTRS SAT RESULTING IN A SLGT
INCREASE IN S WINDS. A STRONGER FRONT WILL MOVE TOWARDS THE REGION
SUN WITH S WINDS INCREASING TO 20-25 KT OVER THE OFFSHORE ZONES SUN
AFTN AND EVE. WINDS WILL RELAX SLIGHTLY MON BEFORE ANOTHER FRONT
