AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
300 AM PST SUN JAN 1 2012

UPDATED AVIATION DISCUSSION

.SHORT TERM...TODAY THROUGH TUESDAY. THE WARM FRONT THAT WAS
EXPECTED TO SPREAD PRECIPITATION ACROSS WESTERN WASHINGTON IS
FALLING APART.  MOST OF THE MOISTURE HAS ALREADY MOVED INTO NORTHERN
WASHINGTON.  WSDOT WEB CAMS ARE SHOWING LIGHT SNOW AT EASTON AND
CLIFFDELL SO WILL KEEP SCATTERED SNOW SHOWERS ALONG THE CASCADE EAST
SLOPES NORTH OF RIMROCK. THE THREAT OF FREEZING RAIN IS MINIMAL BUT
WILL KEEP A SLIGHT CHANCE.  PRECIPITATION SHOULD END BY MID
MORNING.  THE REST OF THE FORECAST AREA WILL BE DRY TODAY WITH
PARTLY TO MOSTLY CLOUDY SKIES AND TEMPERATURES IN THE 30S TO MID
40S.  A DRY FORECAST IS IN STORE THROUGH MONDAY MORNING.  THE UPPER
LEVEL RIDGE WILL SHIFT EASTWARD AND ALLOW A PACIFIC FRONTAL SYSTEM
TO MOVE ONSHORE MONDAY MORNING THEN ACROSS WA/OR ON MONDAY.  ONLY A
20-40 PCT CHANCE OF RAIN AND HIGH ELEVATION SNOW IS EXPECTED (SNOW
LIKELY ALONG THE CASCADE CREST). THE SYSTEM WILL EXIT THE REGION
MONDAY NIGHT...ALTHOUGH THERE WILL BE SCATTERED SNOW SHOWERS ALONG
THE CASCADES AND ISOLATED SNOW SHOWERS OVER THE NORTHERN BLUE
MOUNTAINS AS THE REGION REMAINS UNDER A WESTERLY FLOW ALOFT.  THE
UPPER LEVEL RIDGE WILL REBUILD ON TUESDAY FOR A RETURN TO DRY
CONDITIONS WITH THE EXCEPTION OF THE EAST SLOPES OF THE CENTRAL
WASHINGTON CASCADES THAT MAY SEE LIGHT SNOW ASSOCIATED WITH A WARM
FRONT OVER WESTERN WASHINGTON.

WINDS IN THE GRANDE RONDE VALLEY AT THE BASE OF LADD CANYON HAVE
BEEN SUSTAINED AROUND 25 MPH WITH GUSTS AROUND 35-40 MPH THROUGH THE
NIGHT.  THE MSLP DIFFERENCE FROM ONTARIO TO MEACHAM IS CURRENTLY
5.2MB WHICH IS A LITTLE STRONGER THAN WHAT HIGH RESOLUTION MODELS
HAVE BEEN ADVERTISING.  GRADIENTS WILL TIGHTEN SOME TODAY AND WILL
BE EVEN STRONGER TONIGHT.  HAVE DECIDED TO ISSUE A WIND ADVISORY FOR
THE SOUTHERN PORTION OF THE GRANDE RONDE VALLEY BEGINNING 10 AM THIS
MORNING THROUGH 3 PM MONDAY.  AREAS ALONG THE BLUE MOUNTAIN
FOOTHILLS EAST AND SOUTHEAST PENDLETON WILL ALSO SEE OCCASIONAL WIND
GUSTS TO AROUND 35-45 MPH THROUGH MONDAY AFTERNOON.  WISTER

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...THE REGION WILL START
OUT WITH A SOUTHWESTERLY FLOW WITH A FEW DISTURBANCES BRINGING A
CHANCE OF PRECIPITATION JUST EAST OF THE CASCADES INTO WEDNESDAY.
THEN A COLD FRONT FOLLOWED BY A TROUGH OF LOW PRESSURE WILL MOVE
INLAND WEDNESDAY NIGHT INTO THURSDAY. THIS WILL BRING A CHANCE OF
PRECIPITATION ACROSS THE FORECAST AREA. SNOW LEVELS WILL LOWER
BEHIND THE COLD FRONT...THOUGH THE BRUNT OF THE MOISTURE WILL BE
AHEAD OF THE FRONT. THE TROUGH WILL MOVE EAST...LEAVING THE AREA
UNDER A NORTHWESTERLY FLOW. THIS WILL LEAD TO COOLER TEMPERATURES
AND SHOWERY CONDITIONS AS FURTHER DISTURBANCES WILL BRING A CHANCE
OF RAIN AND MOUNTAIN SNOW SHOWERS EACH DAY INTO THE WEEKEND. MODELS
ARE IN DISAGREEMENT WITH THE TIMING AND STRENGTHS OF THE INDIVIDUAL
DISTURBANCES AT THE END OF THE WEEK...THEREFORE HAVE KEPT A SLIGHT
CHANCE LOWER ELEVATIONS AND HIGHER CHANCE FOR THE MOUNTAINS AT THE
END OF THE EXTENDED TO ACCOUNT FOR THE DIFFERENCES. DMH

.AVIATION...12Z TAFS...VFR CONDITIONS WITH HIGH AND MID LEVEL CLOUDS
WILL PREVAIL AT ALL TAF SITES THROUGH THE NEXT 24 HOURS. SURFACE
WINDS WILL BE LESS THAN 12 KTS ACROSS THE REGION. DMH
