AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
256 PM PST TUE DEC 18 2012

.SHORT TERM...TONIGHT THROUGH THURSDAY...ANOTHER PACIFIC WEATHER
SYSTEM WILL MAKES ITS WAY ACROSS THE AREA AND PROVIDE VARIOUS
WEATHER ELEMENTS TO THE FORECAST AREA.  SOUTHEAST PRESSURE GRADIENTS
WILL BUILD ACROSS THE AREA TOMORROW MORNING.  THIS WILL PROMOTE
BREEZY TO WINDY CONDITIONS BY LATE AFTERNOON ALONG THE FOOTHILLS OF
THE BLUE MOUNTAINS...THE GRANDE RONDE VALLEY...WALLOWA COUNTY...AND
POTENTIALLY VERY WINDY CONDITIONS ACROSS THE SOUTHERN BLUE MOUNTAINS
AND THE SOUTHERN OREGON FOOTHILLS.  WIND HIGHLIGHTS HAVE BEEN ISSUED
FOR SEVERAL OF THE LISTED AREAS.  PLEASE REFER TO PRODUCT PDXNPWPDT
FOR DETAILS ON WATCHES...WARNINGS...OR ADVISORIES.

EASTERLY GRADIENTS WILL ALSO AID IN THE TRAPPING OF COLD AIR ALONG
THE EAST SLOPES OF THE WASHINGTON CASCADES...EASTERN COLUMBIA RIVER
GORGE...THE SIMCOE HIGHLANDS...THE YAKIMA AND KITTITAS VALLEYS.
THERE IS ALSO CONCERN STARTING LATE TOMORROW AFTERNOON FOR
SIGNIFICANT UPSLOPE SNOW SHOWERS ABOVE 4000FT ALONG THE EAST SLOPES
OF THE OREGON CASCADES.  THIS COMBINED WITH A MODERATE TO STRONG
SURFACE GRADIENT COULD PRODUCE HEAVY SNOW AND AREAS OF BLOWING SNOW.
THEREFORE WINTER HIGHLIGHTS HAVE BEEN ISSUED FOR THESE AREAS. PLEASE
REFER TO PRODUCT PDXWSWPDT FOR FURTHER DETAILS ON
WATCHES...WARNINGS...OR ADVISORIES.

.LONG TERM...THURSDAY NIGHT THROUGH SUNDAY...PACIFIC NORTHWEST WILL
BE UNDER THE INFLUENCE OF A MOST SOUTHWEST FLOW THROUGH SATURDAY AS
A DEEP UPPER LEVEL TROUGH REMAINS OFFSHORE. THERE WILL BE CONTINUOUS
SHOWERS ACROSS THE FORECAST AREA AS SURGES OF MOISTURE MOVE THROUGH
THIS PATTERN. SNOW LEVELS WILL RANGE FROM 1000 FEET TO AROUND 3500
FEET. LOWEST SNOW LEVELS WILL BE ALONG THE EAST SLOPES OF THE
WASHINGTON CASCADES AS MODELS CONTINUE TO HOLD ON TO A COLD POOL OF
AIR IN THIS REGION. HIGHEST SNOW LEVELS WILL BE IN SOUTHERN AND
EASTERN PORTION OF THE FORECAST AREA. EVENTUALLY THE UPPER LEVEL
TROUGH WILL MOVE INTO THE PACIFIC NORTHWEST BRINGING COLDER AIR AND
LOWERING SNOW LEVELS. THIS WILL OCCUR LATE SATURDAY AND INTO SUNDAY.
91

SUNDAY NIGHT THROUGH TUESDAY NIGHT...THE GFS AND ECMWF MODELS BEGIN
TO EXHIBIT TIMING DIFFERENCES IN THEIR 12Z RUN SOLUTIONS IN TERMS OF
THE MOVEMENT/SPEED OF A MID/UPPER LEVEL TROUGH MOVING THROUGH THE
INTERIOR PACIFIC NORTHWEST SUNDAY NIGHT. HOWEVER, BOTH THE GFS AND
ECMWF ENSEMBLE RUNS INDICATE A GENERAL INCREASE IN 500MB HEIGHTS
FROM SUNDAY NIGHT THROUGH MONDAY NIGHT BY VIRTUE OF A MID/UPPER
LEVEL RIDGE OF HIGH PRESSURE BUILDING OVER THE REGION, WHICH POINTS
TO MAINLY DRY CONDITIONS THROUGH MONDAY NIGHT. THE FORECAST FOR THE
NEW DAY SEVEN 24-HOUR PERIOD (FROM DAYBREAK TUESDAY THROUGH TUESDAY
NIGHT) HINGES ON THE MODEL THAT HAS BETTER RUN-TO-RUN CONSISTENCY. I
CHOSE TO FOLLOW THE ECMWF MODEL FOR THE POPS FOR TUESDAY AND TUESDAY
NIGHT AS THE 00Z AND 12Z ECMWF MODEL RUNS SHOW VERY GOOD RUN-TO-RUN
CONSISTENCY, WHEREAS THE 00Z AND 12Z GFS RUNS SHOW EXTREMELY POOR
RUN-TO-RUN CONSISTENCY. AS SUCH I GAVE A LOT OF WEIGHT TO THE LATEST
12Z ECMWF RUN, WHICH INDICATES A WARM FRONT PUSHING THROUGH A RIDGE
OF HIGH PRESSURE ALONG THE COAST CAUSING WARM AIR ADVECTION INTO THE
FORECAST AREA RESULTING IN OVERRUNING PRECIPITATION ASSOCIATED WITH
THE WARM FRONT  FOR TUESDAY AND TUESDAY NIGHT. I THEREFORE INCREASED
POPS FOR TUESDAY/TUESDAY NIGHT. SNOW LEVELS WILL BE VERY LOW TUESDAY
AND TUESDAY NIGHT RESULTING IN SNOW IN THE MOUNTAINS AND A MIX OF
RAIN/SNOW AT LOWER ELEVATIONS IN THE LOWER COLUMBIA BASIN.  POLAN

.AVIATION...PREVIOUS DISCUSSION...18Z TAFS...VFR CONDITIONS ARE
EXPECTED THROUGH THE NEXT 24 HOURS, WITH SOME EXCEPTIONS. CLOUD
BASES WILL RANGE BETWEEN 4000 AND 10000 FEET AGL WITH A BROKEN DECK
OF HIGH CIRRUS THIS MORNING  WITH ONLY FEW-SCT LOWER CLOUDS AND CIGS
AT MID/UPPER LEVELS. SCATTERED RAIN OR SNOW SHOWERS WILL BE POSSIBLE
TODAY MAINLY OVER HIGHER TERRAIN AND OVER MOUNTAINS. THERE IS THE
POSSIBILITY OF MVFR CONDITIONS WITH SNOW SHOWERS AT KRDM AND KBDN
THIS AFTERNOON. CONDITIONS AT KDLS WILL BECOME MVFR TO IFR TONIGHT
INTO WEDNESDAY MORNING FROM 12Z/19TH UNTIL 18Z/19TH DUE TO SNOW
DECREASING CIGS AND VIS. WINDS WILL BE 5-15 KTS AT ALL SITES, WHILE
KPSC, KPDT AND KALW MAY SEE SOME HIGHER GUSTS THIS AFTERNOON.  POLAN
