AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
544 PM PST SUN NOV 7 2010

.UPDATE...

...AS OF 530 PM PST...SHOWERS AND THUNDERSTORMS ARE PRESENT OVER
THE COASTAL WATERS. SEVERAL OF THESE CELLS HAVE BECOME INTENSE...
AND HAVE PROMPTED THE ISSUANCE OF A MARINE WEATHER STATEMENT.
SHOWERS ARE EXPECTED TO CONTINUE THROUGH THE REST OF THE
EVENING...AND MAY BRING GUSTY WINDS AND LOCALLY HIGHER WAVES TO
AREAS OF THE COASTAL WATERS.

&&

.PREV DISCUSSION... /ISSUED 248 PM PST SUN NOV 7 2010/

SYNOPSIS...SCATTERED SHOWERS WILL CONTINUE ACROSS NORTHWEST
CALIFORNIA TONIGHT. MONDAY WILL BE DRY...BUT ANOTHER FRONT WILL
BRING MORE RAIN TO THE AREA ON TUESDAY.

DISCUSSION...THE COLD FRONT MOVED ACROSS THE AREA THIS MORNING
AND IS CURRENTLY MOVING FURTHER INLAND. BEHIND THE FRONT COLD AIR
BUILDING IN IS ALLOWING SCATTERED SHOWERS TO DEVELOP OVER THE
AREA. RADAR SHOWS MOST OF THESE SHOWERS ARE LIGHT TO MODERATE IN
INTENSITY AND FAIRLY SHORT IN DURATION. THEY WILL CONTINUE THROUGH
THIS EVENING AND GRADUALLY DIMINISH TONIGHT AS THE ATMOSPHERE
STABILIZES. THE COLD AIR WILL ALSO ALLOW SNOW LEVELS TO DROP TO
AROUND 4000 FT TONIGHT, BUT NO ACCUMULATIONS ARE EXPECTED. MONDAY
WEAK RIDGING WILL PASS OVERHEAD, WHICH WILL PROVIDE A DAY OF DRY
WEATHER. THOUGH, A FEW ISOLATED SHOWERS ARE POSSIBLE ALONG THE
REDWOOD COAST. ANOTHER FRONT WILL MOVE THROUGH THE AREA ON
TUESDAY, BRINGING MORE RAIN. MODELS SEEM TO BE IN GOOD AGREEMENT
WITH QPF SHOWING 1 INCH NEAR THE CA/OR BORDER DECREASING TO 1/2
INCH AROUND CAPE MENDOCINO AND 1/4 INCH SOUTH OF THAT. WARM AIR
AHEAD OF THE FRONT WILL KEEP THE SNOW LEVELS HIGH, BUT AFTER THE
FRONT PASSES THE SNOW LEVELS WILL DROP. IF THERE IS ENOUGH
MOISTURE BEHIND THE FRONT, THEN SNOW SHOWERS WITH ACCUMULATIONS
ARE POSSIBLE TUESDAY NIGHT A FEW THOUSAND FEET UP. HOWEVER,
AMOUNTS LOOK TO BE MINIMAL AND UNCERTAINTY IS HIGH. STROZ

AVIATION...COOL AND MARGINALLY UNSTABLE AIR HAS MOVED INTO THE
REGION IN THE WAKE OF A COLD FRONT. EXCEPT FOR BRIEF MVFR CIGS AND
VSBYS IN SHOWERS...VFR WILL BE THE RULE. FOG MAY FORM ACROSS THE
INTERIOR VALLEYS AS WINDS GO LIGHT OR CALM LATE TONIGHT INTO EARLY
MONDAY MORNING. DJB

MARINE...GRADIENTS WILL REMAIN WEAK TONIGHT THROUGH MONDAY AS A
WEAK TROUGH CLIPS THE NORTHERN WATERS AND HIGH PRESSURE SLOWLY
BUILDS FROM THE WEST. ATMOSPHERE REMAINS WEAKLY UNSTABLE...SO
WINDS MAY BE ERRATIC NEAR STRONG SHOWERS. RIDGE AXIS AND WARMING
ALOFT WILL MOVE OVER THE REGION MON NIGHT WITH THE APPROACH OF A
NEW COLD FRONT. GFS AND NAM12 TIMING WERE IN SYNC WITH A RIBBON OF
STRONG WINDS IN ADVANCE OF THE FRONT ON TUE. LEANED TOWARDS THE
SLIGHTLY MORE AGGRESSIVE NAM12...WITH WIND GUSTS TO 40 KT IN THE
NORTHERN OUTER WATERS. FOR SEAS...SO FAR NOT MUCH SIGN OF THE
INCOMING SWELL...BUT ENP WIND FIELDS APPEARED TO MATCH UP WITH THE
LAST COUPLE OF ASCAT PASSES. SWAN HAS THE SWELL INCREASING TO
10-12 FEET AT 12 SECONDS TONIGHT AND LASTING THROUGH TUESDAY
MORNING. NOT TOO CONFIDENT ON THE DURATION OF THE SWELL EVENT.
NEXT ISSUE IS A LARGER SWELL EXPECTED TO SPREAD INTO THE WATERS
TUE NIGHT AND PERHAPS PEAK NEAR 18 FT BY MIDDAY WED. GFS AND ECMWF
WERE SIMILAR WITH THE DEPTH OF THE LOW AND THE FETCH AREA THAT
GENERATES THIS SWELL...SO FOR NOW WILL GO AHEAD WITH THE ENP/SWAN
WAVE HEIGHTS AND TIMING. DJB
