.PREV DISCUSSION... /ISSUED 420 PM PST WED DEC 28 2011/

SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT...THE NEXT PACIFIC
SYSTEM WILL SWING ACROSS THE REGION TONIGHT. THIS SYSTEM SHOULD
BRING SOME PRECIP TO MOST LOCATIONS, THOUGH THE HEAVIEST PRECIP WILL
BE OVER AND NEAR THE MOUNTAINS. WINDS WILL REMAIN BREEZY TO WINDY
THROUGH THE NIGHT. THE POTENTIAL FOR SURFACING OF WINDS ALOFT FOR
LOCALLY STRONG WIND GUSTS WILL CONTINUE INTO EARLY EVENING ALONG THE
OREGON CASCADE EAST SLOPES. THUS WILL CONTINUE TO CURRENT WIND
ADVISORIES IN CENTRAL AND NORTH CENTRAL OREGON. SNOW LEVELS WILL
RANGE FROM NEAR 5000 FEET OVER CENTRAL WASHINGTON TO NEAR 7000 FEET
OVER MUCH OF NORTHEAST AND CENTRAL OREGON. SNOW LEVELS SHOULD FALL
BY THURSDAY MORNING BEHIND THE NEXT SYSTEM, WITH LEVELS RANGING
BETWEEN 4500 FEET (WASHINGTON ZONES) TO NEAR 6000 FEET (CENTRAL
OREGON). MAY SEE A BIT OF A BREAK IN PRECIP ON THURSDAY. FOR NOW
HAVE KEPT POPS IN THE LIKELY RANGE OVER THE MOUNTAINS WITH SLIGHT
CHANCE TO CHANCE POPS AT THE LOWER ELEVATIONS. DID DRY OUT THE
YAKIMA VALLEY AND PORTIONS OF THE WASHINGTON LOWER COLUMBIA BASIN
THURSDAY AFTERNOON. ANOTHER SYSTEM IS EXPECTED TO MOVE ONSHORE AND
THROUGH THE REGION THURSDAY NIGHT. SNOW LEVELS WILL AGAIN RISE AHEAD
OF THIS NEXT SYSTEM. SOUTH WINDS COULD AGAIN BECOME AN ISSUE
THURSDAY NIGHT. 90

LONG TERM...FRIDAY THROUGH SUNDAY NIGHT...A STRONG COLD FRONT AND
ATTENDANT PRECIPITATION WILL SWEEP ACROSS THE FORECAST AREA ON
FRIDAY FOR AREA WIDE MEASURABLE RAIN AND SNOW. SNOW LEVELS START
AROUND 4000-6000 FT FRIDAY MORNING AND THEN LOWER TO AROUND
3000-4000 FT BY FRIDAY AFTERNOON. THE EAST SLOPES OF THE CENTRAL
WASHINGTON CASCADES MAY RECEIVE  SNOW ACCUMULATIONS OF 5-10 INCHES
AND THE NORTHERN BLUE MOUNTAINS ARE LIKELY TO GET ACCUMULATIONS OF
3-5 INCHES ON FRIDAY. THE COLD FRONT EXITS INTO IDAHO FRIDAY
AFTERNOON. THE ATTENDANT MID/UPPER LEVEL TROUGH MOVES ACROSS THE
FORECAST AREA FRIDAY NIGHT THUS TRIGGERING ADDITIONAL SNOW SHOWERS
IN THE NE MOUNTAINS OF OREGON AND THE BLUE MOUNTAINS IN WASHINGTON
RESULTING IN ADDITIONAL SNOW ACCUMULATIONS OF 4-8 INCHES FRIDAY
NIGHT. SATURDAY A WEAK WARM FRONT WILL BRING A CHANCE OF SOME LIGHT
SNOW TO THE MOUNTAINS. OTHERWISE..SATURDAY LOOKS TO BE DRY WITH
MOSTLY CLOUDY SKIES. SATURDAY NIGHT THROUGH SUNDAY NIGHT A MID/UPPER
LEVEL RIDGE OF HIGH PRESSURE MOVES THROUGH THE INTERIOR PACIFIC
NORTHWEST FOR MAINLY DRY CONDITIONS.  POLAN

MONDAY THROUGH WEDNESDAY NIGHT...AN UPPER LEVEL RIDGE WILL TRY TO
REBUILD OVER THE AREA FOR THE EXTENDED. AS THE RIDGE STRENGTHENS
THERE MAY BE A WEAK DISTURBANCE THAT COULD PROVIDED SHOWERS TO THE
MOUNTAINS OF NORTHEAST OREGON...WHILE THE EAST SLOPES OF THE
CASCADES WILL CONTINUE TO GET SPILL OVER SHOWERS.  SOUTH TO
SOUTHWEST FLOW LOOKS TO BE DOMINATE FOR THE TIME PERIOD AND AREAS
ALONG THE FOOTHILLS OF THE BLUE MOUNTAINS CAN EXPECT TO SEE UPPER
40S TO UPPER 50S FOR HIGHS.  THE LOWER COLUMBIA BASIN AREAS STILL
SHOW A LIGHT NORTH WIND AND MAY BE COOLER. IF THE SOUTH WINDS ARE
STRONG ENOUGH TO REACH THE BASIN THEN EXPECT HIGH TEMPERATURES TO BE
5 TO 10 DEGREES WARMER THAN THE CURRENT FORECAST. ALSO NIGHT TIME
LOWS LOOK TO BE WARMER AS CLOUD COVER INCREASES AND SOUTH FLOW
REMAINS OVER THE AREA.  HAVE BUMPED THE TEMPERATURES UP A FEW
DEGREES...ESPECIALLY ALONG THE FOOTHILLS OF THE BLUE MOUNTAINS AND
CENTRAL OREGON. THE NEXT WEATHER SYSTEM LOOKS TO ARRIVE WEDNESDAY
AFTERNOON AND MAY HAVE ABUNDANT PRECIPITATION ASSOCIATED. WEBER
