AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
455 AM PST SAT FEB 7 2009

.SYNOPSIS...SHORT LIVED HIGH PRESSURE WILL BRING CLEAR SKIES TO
NORTHWEST CALIFORNIA TODAY. A COLD WINTER STORM WILL BRING
RAIN...SNOW AND SOME ISOLATED THUNDERSTORMS TO THE REGION SUNDAY
THROUGH MONDAY.

&&

.SHORT TERM...TODAY THROUGH TUESDAY...WEAK HIGH PRESSURE AND
ASSOCIATED CLEAR SKIES ARE IN PLACE OVER NW CALIFORNIA ALLOWING SOME
PATCHY FOG TO DEVELOP ALONG THE COAST AND IN INLAND VALLEYS THIS
MORNING. THIS SHOULD BURN OFF SHORTLY AFTER SUNRISE GIVING WAY TO A
CLEAR DAY TODAY WITH TEMPS NEAR NORMAL FOR EARLY FEBRUARY. CLEAR
SKIES WONT LAST LONG...AS A RATHER STRONG COLD FRONT IS APPROACHING
THE COAST WITH EXPECTED ARRIVAL IN THE AFTERNOON SUNDAY. MODELS HAVE
BEEN IN PRETTY GOOD AGREEMENT WITH SNOW LEVELS DROPPING TO NEAR 1000
FEET SUNDAY NIGHT. THE CHALLENGE WITH THIS SYSTEM WILL BE THE SNOW
ACCUMULATION. LATEST GUIDANCE SUGGESTS WIDESPREAD ACCUMULATION OF AT
LEAST 2 INCHES ABOVE 2000 FEET WITH ELEVATIONS ABOVE 3000 FEET
ACCUMULATING NEAR 5 INCHES BY 12Z MONDAY. THIS WILL PROMPT A WINTER
STORM ADVISORY FOR INLAND LOCATIONS HOWEVER SEEING AS THE EVENT WILL
NOT START FOR OVER 30 HOURS...HAVE NOT ISSUED THE ADVISORY YET AND
WILL ALLOW 1 MORE CHECK OF FORECAST SNOWFALL ACCUMULATIONS BEFORE
ISSUANCE. THUNDERSTORMS OVER THE COASTAL WATERS AND NEAR THE COAST
ARE POSSIBLE...AS WELL AS SOME SMALL HAIL IN STRONGER SHOWERS THAT
DEVELOP. RAIN/SNOW CHANCES WILL BEGIN TO TAPER OFF LATE IN THE DAY
MONDAY AS THIS SYSTEM MOVES OFF TO THE EAST. ANOTHER COLD FRONT WILL
BE RIGHT ON ITS HEELS BRINGING BACK RAIN/SNOW CHANCES TUESDAY
AFTERNOON. BK

.LONG TERM...TUESDAY NIGHT THROUGH FRIDAY NIGHT...MODELS REMAIN IN
DECENT AGREEMENT WITH A SERIES OF DISTURBANCES MOVING ACROSS NW
CALIFORNIA THROUGH THE END OF THE WEEK. SNOW LEVELS WILL DROP TO
NEAR 2000 FEET IN THE NORTHERN PORTION OF THE AREA WEDNESDAY WITH
THE FIRST IN THIS SERIES. THE SYSTEM PROGGED FOR THURSDAY NIGHT INTO
FRIDAY LOOKS MUCH MORE IMPRESSIVE WITH SNOW LEVELS DROPPING TO NEAR
1000 FEET FRIDAY MORNING. ITS IS OBVIOUSLY TOO FAR OUT TO GET TOO
EXCITED...BUT AS OF NOW IT DOES LOOK LIKE SOME VERY LOW ELEVATION
SNOW MIGHT BE POSSIBLE FRIDAY AFTERNOON. THUNDERSTORMS OVER THE
COASTAL WATERS AND ALONG THE COAST WILL BE POSSIBLE AS THESE SYSTEMS
MOVE OVER THE AREA. SOME SMALL HAIL WILL BE POSSIBLE AS WELL. BK

&&

.AVIATION...ABUNDANT LOW LEVEL MOISTURE ACROSS THE REGION HAS
RESULTED IN WIDESPREAD INLAND VALLEY FOG THIS MORNING...ALONG WITH A
PATCH AROUND HUMBOLDT BAY. KUKI AND KSTS HAVE BOTH BEEN REPORTING
LIFR VSBYS AND CIGS...AND SUSPECT THAT THIS IS REPRESENTATIVE OF THE
INTERIOR VALLEYS THIS MORNING. COASTAL CONDITIONS HAVE BEEN A LITTLE
MORE VARIED AS WEAK OFFSHORE FLOW APPEARS TO BE KEEPING MOST AREAS
TO PATCHY MVFR VSBYS...WITH THE EXCEPTION OF HUMBOLDT BAY WHICH HAS
BEEN IFR. EXPECT SKIES AREA-WIDE TO CLEAR OUT BY LATE MORNING AS
DRIER AIR FILTERS ACROSS THE REGION. BREEZY CONDITIONS ALONG THE
COAST AND OVER RIDGETOPS MAY RESULT IN SOME TURBULENCE THIS
AFTERNOON. ALM

&&

.MARINE...STRENGTHENING HIGH PRESSURE OVER THE EAST PACIFIC
INTERACTING WITH THE AREA OF LOW PRESSURE OVER THE SIERRAS CONTINUES
TO RESULT IN STRONG NORTHERLY WINDS OVER THE WATERS EARLY THIS
MORNING. NEARSHORE WATERS HAVE BEEN REPORTING SOLID ADVISORY LEVEL
WINDS OVERNIGHT...WITH SHIP OBS OVER THE OFFSHORE WATERS NOTING GALE
FORCE WINDS. THE WIND DRIVEN WAVES INTERACTING WITH AN INCREASING
LONGER PERIOD NW SWELL HAVE RESULTED IN FAIRLY LARGE AND STEEP SEAS.

WINDS WILL BEGIN TO DECREASE LATER THIS AFTERNOON AS THE LOW MOVES
FURTHER TO THE EAST AND THE PRESSURE GRADIENT RELAXES OVER THE
REGION. SEAS WILL TRANSITION LATER TODAY FROM A MIX OF STRONG WINDS
WAVES AND SWELL TO MORE UNDER THE INFLUENCE OF THE LONGER PERIOD
SWELL. WINDS ARE EXPECTED TO BRIEFLY VEER TO THE S-SW ON SUNDAY AS
ANOTHER FRONTAL SYSTEM PUSHES THROUGH THE REGION...WITH ANOTHER
ROUND OF STRONG NORTHERLY WINDS EXPECTED BEHIND THIS SYSTEM SUNDAY
NIGHT. CURRENT WARNINGS AND ADVISORIES LOOK GOOD TO COVER TODAYS
WINDS AND SEAS.

MODELS SHOW A LARGE SWELL TRAIN PUSHING INTO THE REGION MID WEEK AS
ANOTHER SURFACE LOW MOVES INTO THE PAC NW. BOTH THE SWAN AND THE ENP
ARE CONSISTENT WITH BRINGING SEAS ABOVE 20 FT WEDNESDAY INTO
THURSDAY...AND HAVE ADJUSTED THE FORECAST UPWARDS TO JUST BELOW 20
FT TO ACCOUNT FOR THIS LARGE TRAIN. ALM
