AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
230 PM PST THU FEB 12 2009

.SYNOPSIS...VERY LIGHT SCATTERED SHOWERS WILL CONTINUE THROUGH THE
EVENING HOURS OVER NORTHERN CALIFORNIA.  A COLD FRONT WILL MOVE
ACROSS NORTHERN CALIFORNIA TONIGHT BRINGING MORE WIDESPREAD RAIN AND
SNOW TO THE REGION.

&&

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...SATELLITE IMAGERY
THIS AFTERNOON CLEARLY SHOWS A COLD FRONT MAKING ITS WAY TOWARD NW
CALIFORNIA. THIS STORM IS EXPECTED TO BE A LITTLE STRONGER THAN THE
LAST STORM...WITH FORECAST SNOW TOTALS PROMPTING A WINTER STORM
WARNING FOR ZONES 3 AND 4...AND A WINTER WEATHER ADVISORY POSTED FOR
ZONE 76. RAIN CAN BE EXPECTED BELOW THE SNOW LEVEL ACROSS THE
AREA...WITH SOME SHOWERS THAT PASS OVERHEAD AFTER THE FRONT PASSES
CONTAINING SMALL HAIL.

THE BULK OF THE SNOW WILL FALL TONIGHT...MAKING FOR SNOW COVERED
PASSES ALONG HIGHWAYS 299 AND 36 IN THE MORNING HOURS. SNOW TOTALS
ABOVE 3000 FT...MAY VERY SEE 20 INCHES IN SNOW PRONE AREAS WITH
WIDESPREAD SNOW TOTALS ABOVE 3000 FEET VARYING BETWEEN 12 AND 16
INCHES. AREAS ABOVE 1000 FEET BUT LESS THAN 3000 FEET WILL LIKELY
SEE SNOW TOTALS APPROACH 5 TO 8 INCHES COME FRIDAY MORNING. REFER TO
SFOWSWEKA FOR ADDITIONAL INFORMATION.

EXPECT THIS SYSTEM TO PASS OFF TO THE EAST BY FRIDAY NIGHT WITH
ANOTHER PACIFIC STORM RIGHT ON ITS HEELS. THIS STORM WILL BE A BIT
WARMER WITH SNOW LEVELS RISING ABOVE 2500 FEET COME SUNDAY
AFTERNOON. BK

.LONG TERM...SUNDAY THROUGH WEDNESDAY...EXTENDED FORECAST MODELS
IN GOOD AGREEMENT ON A FAIRLY STRONG FRONT MOVING THROUGH THE
CWA EARLY SUNDAY. AT THIS TIME CURRENT PRODUCTS REFLECTING THE SHORT
TERM IMPACTS HAVE PRECLUDED ANY WATCHES FOR SUNDAY.  GIVEN THE HIGH
QPF WITH SUNDAYS SYSTEM AND CONTINUED LOW SNOW LEVELS IT IS QUITE
LIKELY THAT THIS FEATURE WILL REQUIRE ANOTHER WINTER STORM WARNING
FOR SNOW ACROSS THE INTERIOR ZONES THROUGH MONDAY.  A BRIEF BREAK IN
PRECIPITATION OCCURS TUESDAY FOLLOWED BY ANOTHER SIGNIFICANT FRONT
ON WEDNESDAY.  THIS SYSTEM LOOKS TO BE A LITTLE WARMER WITH A SUBTLE
SUBTROPICAL TAP INTO MOISTURE DOWN AROUND 20-30N.  QPF AT THIS TIME
IS IN THE 2 TO 4 INCH RANGE FOR RAIN AND ALTHOUGH GFS AND ECMWF ARE
IN PHASE AS FAR AS STRENGTH AND PRECIP OUTPUT...THEY ARE OUT OF
PHASE ON TIMING. NONETHELESS IF THE QPF AMOUNTS HOLD WE COULD BE
LOOKING A MORE TRADITIONAL WARM RAIN EVENT...AS SNOW LEVELS APPEAR
TO BE IN EXCESS OF 5000 FT.

&&

.AVIATION...THE COLD FRONT THAT WILL SWEEP THROUGH THE REGION THIS
AFTERNOON WILL BE ACCOMPANIED BY LIGHT RAIN SHOWER ACTIVITY THAT MAY
AT TIMES REDUCE VISIBILITIES TO MVFR CONDITIONS AND TO IFR IN AREAS
OF THE MOST INTENSE PRECIPITATION. CIGS SHOULD REMAIN IN THE MVFR
CATEGORY THROUGHOUT THE AFTERNOON.  RAIN WILL BE HEAVIEST FOR THE
NORTHERN PORTION OF THE CWA BETWEEN THE HOURS OF 00Z AND 6Z, AND
HEAVIEST FOR THE SOUTHERN PORTION BETWEEN 6Z AND 12Z. SURFACE WINDS
ACROSS THE REGION WILL BE OUT OF THE SOUTH FOR THE REMAINDER OF
FRIDAY EVENING AT 5 KNOTS INLAND AND AROUND 15 KNOTS AT THE COAST.
AS THE FRONT PASSES BETWEEN 06Z AND 09Z, WINDS WILL SHIFT TO THE
WEST. OVERNIGHT...THE PRECIPITATION SHOULD COME TO AND END AFTER
MIDNIGHT AND SKIES WILL CLEAR. AMPLE MOISTURE AT THE SURFACE MAY
ALLOW LIGHT FOG TO FORM JUST BEFORE SUNRISE, ESPECIALLY IN VALLEYS
AND COASTAL REGIONS, BUT VISIBILITIES SHOULD NOT DROP BELOW MVFR
CONDITIONS. INTO THE DAY TOMORROW, SKIES WILL REMAIN PARTLY CLOUDY
AS OUR NEXT STORM SYSTEM WILL NOT APPROACH UNTIL EARLY IN THE DAY ON
SATURDAY.

&&

.MARINE...A MODERATE STORM WILL MOVE ACROSS THE WATERS TONIGHT NIGHT
INTO FRIDAY...BRINGING INCREASED SOUTHERLY WINDS AND HIGH SEAS. WINDS
SHOULD REMAIN BELOW GALE FORCE DURING THIS WEATHER FEATURE HOWEVER
ANOTHER LARGE NORTHWESTERLY SWELL IS EXPECTED TO PEAK NEAR 23 FT AT
13 SECONDS ON FRIDAY AFTERNOON BEFORE IT QUICKLY SUBSIDES LATE
FRIDAY NIGHT. THUS...A HAZARDOUS SEAS WARNING FOR ALL WATERS IS NOW
IN EFFECT FROM FRIDAY MORNING THROUGH EARLY SATURDAY MORNING. A
HIGH SURF ADVISORY IS ALSO IN EFFECT FOR THE ENTIRE COAST TO REFLECT
THE HIGH BREAKERS ASSOCIATED WITH THE SWELL. BREAKER HEIGHTS OF 23
TO 27 FT ARE EXPECTED...ESPECIALLY ALONG NORTHWEST FACING BEACHES.
THE SWELL WILL SUBSIDE LATE FRIDAY NIGHT. YET ANOTHER STORM WILL
MOVE ACROSS THE WATERS OVER THE WEEKEND. THIS STORM WILL BRING MORE
HAZARDOUS SEAS ALONG WITH A HIGHER POTENTIAL OF GALE FORCE WINDS.
