AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
245 PM PST SUN NOV 11 2012

.SHORT TERM...TONIGHT THROUGH MONDAY...THE NEXT PACIFIC SYSTEM HAS
MOVED EAST OF 130W, AND HAS PUSHED PRECIP INTO WESTERN WASHINGTON
AND OREGON. THIS PRECIP HAS REACHED THE CASCADE CREST FROM MOUNT
HOOD NORTH INTO WASHINGTON. THIS PRECIP WILL GRADUALLY SPREAD EAST
TONIGHT, FIRST ATTACHED TO A WARM FRONT THAT WILL BE QUICKLY
FOLLOWED BY A PACIFIC COOL FRONT MONDAY. EXPECT ALMOST ALL LOCATIONS
TO PICK UP SOME MEASURABLE PRECIP. HEAVIEST PRECIP LOOKS TO OCCUR
ACROSS CENTRAL AND SOUTH-CENTRAL WASHINGTON, PRIMARILY FROM MID
EVENING INTO VERY EARLY MONDAY MORNING. SNOW LEVELS WILL GENERALLY
RUN FROM 2000 FEET NEAR THE COLUMBIA RIVER GORGE TO 1000 FEET IN
YAKIMA AND KITTITAS COUNTIES. DEW POINT TEMPS ARE IN THE MID 20S IN
KITTITAS COUNTY, THUS AS PRECIP STARTS THE AIR TEMP SHOULD FALL TO
FREEZING WITH ALMOST ALL PRECIP TO BE SNOW IN THIS AREA TONIGHT.
YAKIMA VALLEY SHOULD SEE SNOW ABOVE 1000 FT WITH MOSTLY RAIN BELOW,
AS DEW POINTS ARE NEAR 30. THUS HAVE ADDED A SNOW ADVISORY TONIGHT
FOR PORTIONS OF THE YAKIMA VALLEY, WHILE CONTINUING THE WARNING AND
ADVISORIES ALREADY OUT IN SOUTH-CENTRAL WASHINGTON. SNOW LEVELS
ACROSS THE BASIN AND FOOTHILLS WILL RUN BETWEEN 1200 AND 2000 FT
TONIGHT THUS SNOW WILL BE LIMITED IN THESE ZONES. CENTRAL AND
NORTH-CENTRAL OREGON WILL START WITH SNOW LEVELS IN THE 2000 TO 3000
FOOT RANGE, AND THESE ARE EXPECTED TO RISE LATER TONIGHT. PRECIP
AMOUNTS LOOK TO BE LIGHT, AND WILL NOT GO WITH HIGHLIGHTS FOR THIS
AREA AT THIS TIME. THESE ZONES SHOULD BE MONITORED THOUGH. THE SNOW
LEVELS LOOK TO REMAIN LOWER ACROSS GRANT AND EASTERN CROOK COUNTIES.
THERE LOOKS TO BE ENOUGH PRECIP FOR 2-4 INCHES OF SNOW LATE TONIGHT
INTO MONDAY MORNING. THUS WILL RUN ADVISORIES FOR THESE AREAS. THE
NORTHERN BLUES LOOK TO SEE LESS THAN 5 INCHES, WHILE WALLOW COUNTY
AND THE GRANDE RONDE VALLEY SHOULD SEE 2 INCHES OR LESS. THE
PRESSURE GRADIENT ACROSS THE SOUTHERN GRANDE RONDE VALLEY WILL
TIGHTEN FOR SOME STRONGER WINDS LATER TONIGHT INTO MONDAY. THUS WILL
GO WITH A WIND ADVISORY IN THIS AREA. 90

.LONG TERM...MONDAY NIGHT THROUGH THURSDAY...MONDAY NIGHT A COLD
FRONT WILL MOVE THROUGH EASTERN OREGON. PRECIPITATION WILL DECREASE
OVERNIGHT AND BECOME SHOWERY. THERE WILL BE ENOUGH INSTABILITY TO
KEEP A CHANCE OF PRECIPITATION OVER THE CWA. WESTERLY MID LEVEL
WINDS WILL DEVELOP BEHIND THE FRONT. UPSLOPE EFFECTS WILL KEEP
PRECIPITATION LIKELY IN THE MOUNTAINS. TUESDAY AN UPPER LEVEL TROUGH
WILL DIG OFF THE COAST. A CUTOFF LOW WILL DEVELOP IN THE BASE OF THE
TROUGH TUESDAY NIGHT...RESULTING IN WEAK RIDGING OVER WASHINGTON AND
OREGON. A DISTURBANCE WILL MOVE THROUGH THE RIDGE IN EASTERN OREGON
TUESDAY NIGHT KEEPING A CHANCE OF SHOWERS OVER OREGON. TEMPERATURES
WILL INCREASE PARTICULARLY IN THE HIGHER ELEVATIONS WITH THE
RIDGING. THURSDAY THE RIDGING WILL MOVE INTO EASTERN WASHINGTON AND
OREGON WITH DRIER CONDITIONS. A FEW SHOWERS MAY LINGER OVER THE
MOUNTAINS. COONFIELD

THURSDAY NIGHT THROUGH SUNDAY...MODELS SHOW WEAK RIDGING BEING
DISPLACED BY A WEAK TROUGH THURSDAY NIGHT AND FRIDAY. MODELS
DISAGREE IN THEIR HANDLING OF THIS SYSTEM AS THE GFS PUTS MOST OF
THE PRECIPITATION INTO THE WASHINGTON CASCADES WHILE THE ECMWF SENDS
MOST OF IT INTO CENTRAL OREGON AND THE EASTERN MOUNTAINS.
COMPROMISED WITH A CHANCE OF MAINLY RAIN IN THE MOUNTAINS AND A
SLIGHT CHANCE IN THE LOWER ELEVATIONS. THE RAIN WILL TAPER OFF TO
SHOWERS IN THE MOUNTAINS AND CENTRAL OREGON FRIDAY NIGHT. SNOW
LEVELS WILL REMAIN ABOVE 5000 FEET WITH THIS SYSTEM. SATURDAY
THROUGH SUNDAY, A STRENGTHENING RIDGE WILL BE OVER THE ROCKIES WHILE
A DEEP TROUGH OUT IN THE EASTERN PACIFIC WILL SEND A SOUTHWEST FLOW
OVER THE AREA. THE TROUGH WILL HAVE A FAIRLY STRONG FRONT BUT IT
WILL HAVE A TOUGH TIME MOVING ASHORE WITH THE RIDGE OVER THE
ROCKIES. MODELS ARE IN AGREEMENT IN KEEPING THE FRONT OUT OF THE
AREA SATURDAY AND SATURDAY NIGHT. THE ECMWF BRINGS THE SYSTEM TO THE
CASCADE CREST SUNDAY AFTERNOON WITH SHOWERS MAINLY ALONG THE CREST
BUT INTO CENTRAL OREGON AS WELL. THE GFS KEEPS IT OFFSHORE ON
SUNDAY. KEPT THE AREA MAINLY DRY ASIDE FROM RAIN SHOWERS IN THE
CASCADES SATURDAY AND SATURDAY NIGHT THEN BROUGHT IN A SLIGHT CHANCE
OF RAIN SHOWERS SUNDAY IN CENTRAL OREGON AND THE MOUNTAINS. HIGH
TEMPERATURES WILL BE IN THE MID 40S TO LOWER 50S WITH LOWER TO MID
40S IN THE MOUNTAINS. NIGHT TIME LOWS WILL BE IN THE LOWER TO MID
30S WITH MAINLY 20S IN THE MOUNTAINS THURSDAY AND FRIDAY NIGHTS THEN
WARM TO THE MID TO UPPER 30S WITH MID 20S TO MID 30S IN THE
MOUNTAINS SATURDAY NIGHT. PERRY

.AVIATION...PREVIOUS DISCUSSION...18Z TAFS...LOW LEVEL MOISTURE IS
CONTINUING TO CREATE LOW MVFR STRATUS AT KYKM AND KDLS AND LIFR
CEILINGS AND VISIBILITY AT KPSC. BELIEVE THIS WILL GRADUALLY IMPROVE
OVER THE NEXT FEW HOURS TO VFR LEVELS THOUGH KDLS IS EXPECTED TO
KEEP MVFR CEILINGS. A WARM FRONT WILL MOVE INTO THE AREA LATE THIS
AFTERNOON AND TONIGHT. CEILINGS WILL LOWER TO MVFR LEVELS THIS
EVENING AND PRECIPITATION WILL BEGIN IN THE WEST SHORTLY AFTER 00Z
AND IN THE EAST AFTER 05Z. INITIALLY PRECIPITATION WILL BE SNOW AT
KYKM, KRDM AND KBDN BUT WILL SWITCH TO A RAIN/SNOW MIX AFTER
MIDNIGHT AND BECOME ALL RAIN AFTER 12Z-15Z. OTHER TAF SITES WILL
HAVE RAIN. PRECIPITATION WILL BE HEAVY FROM 04-12Z AND MVFR/IFR
CONDITIONS ARE EXPECTED WITH THE HEAVIER BANDS OF PRECIPITATION.
USED PROB30 AT ALL TAF SITES TO INDICATE THE EXPECTED HIGH
PRECIP/LOW CLOUD AND VISIBILITY PERIODS. SURFACE WINDS WILL REMAIN
BELOW 15 KTS FOR THE NEXT 24 HOURS. PERRY
