AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE PENDLETON OR
357 AM PST WED JAN 8 2014

UPDATED AVIATION DISCUSSION AND WATCHES/WARNINGS/ADVISORIES SECTION

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT.  A VERY ACTIVE AND
COMPLEX PATTERN HAS SET UP OVER THE PACIFIC NW THAT WILL CONTINUE
THROUGH THE WEEKEND.  CURRENTLY...A SHORTWAVE HAS MOVED ACROSS THE
FORECAST AREA AND IS LOCATED JUST SOUTH OF JOHN DAY AT THIS TIME.
MOISTURE AND WEAK WARM AIR ADVECTION AHEAD OF THE SYSTEM BROUGHT
AREAS OF SNOW, FREEZING RAIN AND SLEET TO THE REGION.  THE WINTER
WEATHER ADVISORY FOR MIXED PRECIPITATION OVER THE COLUMBIA BASIN,
BLUE MTN FOOTHILLS, THE KITTITAS AND YAKIMA VALLEYS, AND THE EAST
SLOPES OF THE WASHINGTON CASCADES EXPIRES AT 4 AM THIS MORNING.  THE
ODDS OF EXTENDING THIS LATER THIS MORNING ARE NOT LIKELY AS
PRECIPITATION IS VERY PATCHY AND MOST OF OBSERVATIONS ARE HOVERING
AROUND 32F. ROAD TEMPERATURES ARE ALSO IN THE LOWER TO MID 30S EAST
OF RICHLAND, WA.  WILL HANDLE WITH NOWCASTS.

THE NEXT UPPER LEVEL SYSTEM WILL MOVE ONSHORE LATE THIS AFTERNOON
THEN TRAVERSE ACROSS WA/OR TONIGHT.  MOISTURE AHEAD OF THE SYSTEM
AND A NW FLOW ALOFT WILL CONTINUE TO BRING RAIN AND MOUNTAIN SNOW AS
THE DAY PROGRESSES.  COLD AIR TRAPPED ALONG THE EAST SLOPES OF THE
WASHINGTON CASCADES AND THE KITTITAS VALLEY MAY RESULT IN LOCAL
FREEZING RAIN.  SNOW LEVELS WILL SLOPE UPWARDS FROM 1500 FEET OVER
THE CENTRAL WASHINGTON CASCADES TO 4000 FEET OVER NORTHERN OREGON TO
5000 FEET OVER CENTRAL OREGON.  WINDS WILL ALSO INCREASE BEHIND THE
SHORTWAVE TROUGH TONIGHT.  UPCOMING SHIFTS WILL NEED TO MONITOR
WINDS IN CENTRAL OREGON.  MODELS ARE HINTING AT A LEE SIDE TROUGH
OVER CENTRAL OREGON THAT MAY FORCE STRONG WINDS ALOFT TO THE
SURFACE.  FOR NOW...WILL KEEP WINDS JUST BELOW ADVISORY FOR THIS
AREA.  THE TROUGH WILL EXIT THE REGION BY LATE THURSDAY MORNING.
24-HOUR SNOW ACCUMULATIONS OF 5-9 INCHES ARE FORECAST FOR THE EAST
SLOPES OF THE WASHINGTON AND OREGON CASCADES...AND 6-10 INCHES ARE
FORECAST FOR THE NORTHERN BLUE MOUNTAINS ABOVE 4000 FEET.  THESE
AMOUNTS MEET ADVISORY CRITERIA...AND ONE WILL BE ISSUED THIS MORNING.

A STRONG AND VERY MOIST WESTERLY FLOW WILL DEVELOP THURSDAY
AFTERNOON AND THURSDAY NIGHT.  THE CASCADES AND THE BLUE MOUNTAINS
WILL LIKELY GET A 6-12 HOUR PERIOD OF SNOW THURSDAY NIGHT. ANOTHER
WINTER HIGHLIGHT MAY BE NEEDED.  ONE VERY INTERESTING FEATURE ON THE
MODELS IS A PRONOUNCED LEE SIDE TROUGH OFF THE WASHINGTON CASCADES
LATE THURSDAY NIGHT. NAM12 HAS CONSISTENTLY ADVERTISED VERY STRONG
WINDS IN THE BOUNDARY LAYER.  THE 06Z NAM12 HAS 65 KNOTS AT 850 MB.
CROSS SECTIONS INDICATE THE POTENTIAL FOR VERTICALLY PROPAGATING
MOUNTAIN WAVE THAT COULD BRING DAMAGING WINDS TO THE SIMCOE
HIGHLANDS AND THE YAKIMA VALLEY.  DUE TO THE EXTREMELY HIGH IMPACT
SITUATION THAT MAY OCCUR DURING THE NIGHT...I WILL ISSUE A HIGH WIND
WATCH FOR THIS AREA THURSDAY NIGHT.  WISTER

.LONG TERM...FRIDAY THROUGH TUESDAY...A WAVE IMBEDDED WITHIN
NORTHWEST FLOW EAST OF AN UPPER RIDGE JUST OFFSHORE WILL SWING
ACROSS THE REGION FRIDAY. THIS WAVE WILL INTERACT WITH WARM AIR
ADVECTION ALOFT TO PRODUCE VARYING AMOUNTS OF PRECIP OVER THE AREA
FRIDAY INTO FRIDAY NIGHT. SNOW LEVELS WILL RISE FRIDAY AND FRIDAY
NIGHT, THUS DO NOT EXPECT SIGNIFICANT SNOW BELOW 6000 FT DURING THIS
PERIOD. A STRONGER SYSTEM WILL PUSH TO THE COAST SATURDAY MORNING
THEN MOVE ACROSS THE REGION SATURDAY AFTERNOON AND EVENING. WINDS
LOOK TO BE BREEZY TO LOCALLY WINDY AHEAD OF AND BEHIND THE SYSTEM'S
COLD FRONT. THERE IS THE POTENTIAL FOR SOME AREAS BECOMING VERY
WINDY SATURDAY. SNOW LEVELS WILL FALL BEHIND THE COLD FRONT. PRECIP
WILL ALSO WIND DOWN AFTER FRONTAL PASSAGE, THUS DO LOOK FOR
SIGNIFICANT SNOW, THOUGH AREAS NEAR THE WASHINGTON CASCADE CREST MAY
NEED TO BE WATCHED FOR PERSISTENT SLOP OVER SNOW. A RIDGE WILL
GRADUALLY BUILD OVER THE AREA SUNDAY THROUGH TUESDAY. SLOP OVER
PRECIP ALONG THE CASCADES AND UPSLOPE INDUCED PRECIP INTO THE BLUES
SHOULD PERSIST THROUGH SUNDAY. THIS PRECIP WILL GRADUALLY END FROM
SOUTH TO NORTH SUNDAY NIGHT INTO MONDAY. TEMPS SHOULD RUN ABOVE
SEASONAL FRIDAY THROUGH SUNDAY, THEN DROP TO NEAR SEASONAL BY EARLY
NEXT WEEK. 90

&&

.AVIATION...12Z TAFS...WESTERLY FLOW WILL KEEP CONDITIONS MOSTLY
CLOUDY WITH A FEW LINGERING MOUNTAIN SHOWERS THIS MORNING. ANOTHER
PACIFIC SYSTEM WILL MOVE INTO THE REGION BRINGING SHOWERS TO MOST
AREAS THIS AFTERNOON AND/OR EVENING. EXPECT MAINLY VFR CONDITIONS AT
KRDM AND KBDN THROUGH THE PERIOD THOUGH SOME MVFR CONDITIONS WILL BE
POSSIBLE DUE TO SHOWERS THIS EVENING. MVFR CONDITIONS SHOULD PERSIST
AT KPSC AND KYKM THROUGH TODAY. THOUGH THERE MAY SOME BREAKS AT
THESE SITES IN THE AFTERNOON, WILL FOR NOW KEEP THEM MVFR. YKM MAY
SEE BRIEF IFR CONDITIONS AROUND SUNRISE. EXPECT MOSTLY VFR CIGS WITH
MVFR OR IFR VIS AT KDLS THROUGH TODAY. UPSLOPE FLOW OF MOIST AIR
INTO KALW AND KPDT HAVE BEEN CAUSING LIFR AND VLIFR CONDITIONS.
THESE CONDITIONS MAY FLUCTUATE SOME, BUT WILL GENERALLY PERSIST INTO
MID MORNING. SHOULD SEE IMPROVEMENT TO MVFR CONDITIONS BY LATE
MORNING OR EARLY AFTERNOON. EXPECT WINDS TO INCREASE THIS EVENING
AND OVERNIGHT WITH THE PASSAGE OF THE NEXT SYSTEM. THESE WINDS
SHOULD CAUSE A RETURN TO MAINLY VFR CONDITIONS AT ALL SITES. 90
