AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
226 PM PST THU FEB 23 2012

.SHORT TERM...TONIGHT THROUGH SUNDAY...SOUTHEAST WASHINGTON AND EAST
OREGON WILL BE DRY TONIGHT AS A RIDGE BUILDS OFFSHORE. SOME HIGH
CLOUDS WILL MOVE INTO THE AREA IN THE NORTHWEST FLOW ALOFT AS A WARM
FRONT MOVES THROUGH NORTHWEST WASHINGTON AND SOUTHERN CANADA LATE
TONIGHT AN FRIDAY...BUT THE MAIN LIFT IS TOO FAR NORTH FOR
PRECIPITATION TO AFFECT OUR CWA.

A COLD FRONT WILL MOVE ACROSS THE PACIFIC NORTHWEST FRIDAY NIGHT
BRINGING WIDESPREAD PRECIPITATION TO THE CWA. AN UPPER LEVEL TROUGH
WILL KEEP CONVECTIVE SHOWERS OVER EASTERN WASHINGTON AND OREGON
THROUGH AT LEAST SUNDAY. SNOW LEVELS WILL DROP TO 2000-3000 FT
SATURDAY AND TO 1000 FT SATURDAY NIGHT AND SUNDAY. SNOW WILL
ACCUMULATE IN THE CASCADES AND NORTHERN BLUE MOUNTAINS FRIDAY NIGHT
THROUGH SUNDAY...AND PROBABLY WILL REACH ADVISORY CRITERIA OF 5-9
INCHES OVER THE EAST SLOPES OF THE WASHINGTON CASCADES.

THE MAIN THREAT WITH THE COLD FRONT AND UPPER LEVEL TROUGH WILL BE
BREEZY TO WINDY CONDITIONS OVER MOST OF THE AREA LATE FRIDAY NIGHT
AND SATURDAY. THERE IS POTENTIAL FOR A MOUNTAIN WAVE TO DEVELOP OVER
NORTH CENTRAL OREGON AFTER MIDNIGHT FRIDAY. THIS MAY CREATE HIGH
WINDS WEST OF HIGHWAY 97 WITH BREEZY TO WINDY CONDITIONS IN THE REST
OF THE ZONE. SATURDAY WIDESPREAD WINDY CONDITIONS WILL DEVELOP OVER
THE LOWER COLUMBIA BASIN AND NORTHEAST OREGON AS PRESSURE GRADIENTS
TIGHTEN BEHIND THE FRONT AND HIGHER WINDS ALOFT MIX TO THE SURFACE.
WINDS WILL GRADUALLY DECREASE SATURDAY NIGHT AND SUNDAY WHEN
PRESSURE GRADIENTS WEAKEN.  COONFIELD

.LONG TERM...SUNDAY NIGHT THROUGH TUESDAY NIGHT...AN UPPER LEVEL
TROUGH WILL DIVE SOUTHWARD ACROSS THE INTERIOR PACIFIC NORTHWEST
SUNDAY NIGHT. SNOW LEVELS SUNDAY NIGHT WILL BE LOW ENOUGH FOR SNOW,
EXCEPT ALONG THE COLUMBIA RIVER WHERE RAIN OR A RAIN/SNOW MIX IS
EXPECTED. MONDAY THE TROUGH MOVES OUT OF THE FORECAST AREA INTO
IDAHO WHILE HIGH PRESSURE RIDGE ARRIVES ON THE COAST IN THE
AFTERNOON. NORTHERN FLOW ALOFT WILL PROVIDE OROGRAPHIC LIFT ALONG
NORTH FACING SLOPES IN THE MOUNTAINS FOR A CHANCE OF SNOW SHOWERS
IN THE BLUE MOUNTAINS, THE WALLOWA MOUNTAINS AND ALONG SUMMIT RIDGE
IN EASTERN WALLOWA COUNTY. THE RIDGE OF HIGH PRESSURE BUILDS OVER
THE REGION MONDAY NIGHT WITH SUBSIDENCE PRODUCING CLEARING SKIES IN
SOUTHEAST WASHINGTON AND NORTHEAST OREGON AND THUS DRY CONDITIONS
MONDAY NIGHT THROUGHOUT THE FORECAST AREA. TUESDAY THE RIDGE
FLATTENS OUT AND MOVES TO THE IDAHO BORDER IN THE AFTERNOON THUS
ALLOWING A STRONG UPPER LEVEL TROUGH MOVING SOUTHEASTWARD OUT OF THE
GULF OF ALASKA TO SPREAD INCREASING MOISTURE TO THE WASHINGTON
CASCADE CRESTS IN THE AFTERNOON RESULTING IN A CHANCE OF SNOW
TUESDAY AFTERNOON ALONG THE EAST SLOPES OF THE CENTRAL AND SOUTHERN
WASHINGTON CASCADES. TUESDAY NIGHT THE TROUGH PUSHES A COLD FRONT
INTO THE FORECAST AREA FOR SNOW LIKELY IN THE MOUNTAINS. SNOW LEVELS
WILL BE 1000-1500 IN SOUTHEAST AND SOUTH CENTRAL WASHINGTON AND
1500-3000 FEET IN CENTRAL, NORTH CENTRAL, AND NORTHEAST OREGON. AS
SUCH HIGHER TERRAIN WILL LIKELY RECEIVE MEASURABLE SNOW TUESDAY
NIGHT ON THE ORDER OF 2-3 INCHES WITH A GOOD CHANCE OF RAIN MIXED
WITH SNOW IN THE LOWER COLUMBIA BASIN BELOW 1500 FEET.  POLAN

WEDNESDAY THROUGH THURSDAY NIGHT...MODELS ARE IN GOOD AGREEMENT OF A
COLD FRONT TO PASS THROUGH THE AREA IN THE EXTENDED. SHOWER ACTIVITY
WILL LIKELY BE RAIN IN THE LOWER ELEVATIONS AND SNOW IN THE
MOUNTAINS.  THERE MAY BE A RAIN SNOW MIX OVERNIGHT WEDNESDAY ACROSS
THE LOWER ELEVATIONS. WINDS ARE ALSO EXPECTED TO PICK UP WITH THE
FRONTAL SYSTEM AND SOME AREAS COULD BE BREEZY TO WINDY.  CONFIDENCE
IS GOOD DUE TO REASONABLE AGREEMENT IN MODEL DATA.  WEBER

.AVIATION...00Z TAFS...VFR CONDITIONS AND DRY CONDITIONS WILL OCCUR
FOR THE NEXT 24 HOURS AS HIGH PRESSURE ALOFT BUILDS EASTWARD OVER
THE REGION. SCT-BKN MID/HIGH CLOUDS THROUGH THIS AFTERNOON WILL GIVE
WAY TO CLOUD BASES LOWERING TO 050-080 FT AGL THIS EVENING THROUGH

CLEARING BY AROUND 24/12Z. WINDS AT KDLS WILL INCREASE TO 15G25KT BY
EARLY THIS AFTERNOON AND THEN DECREASE AROUND SUNSET TO LESS THAN 10
KTS. OTHERWISE, WINDS WILL CONTINUE TO DIMINISH OVER THE NEXT 24
HOURS DUE TO WEAKENING SURFACE PRESSURE GRADIENTS. POLAN
