AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PENDLETON OR
345 PM PST MON NOV 16 2009

UPDATED AVIATION DISCUSSION

.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT...AN UPPER LEVEL LOW
CONTINUES TO BUILD OFFSHORE AND DIG SOUTHWARD. A FRONT DRAPED ALONG
THE COAST IS ACTING TO CONVEY MOISTURE INTO THE AREA ON A SOUTHWEST
FLOW. THIS WILL CONTINUE THE GENERALLY CLOUDY CONDITIONS THROUGH
TOMORROW NIGHT. SHOWERS CONTINUE ALONG THE WASHINGTON CASCADES AND
WILL GRADUALLY PROGRESS INTO THE AREA DURING THE NEXT 24 HOURS.
SHOWERS WILL BE CONFINED TO THE CASCADES TONIGHT AND WITH SNOW
LEVELS HIGH FROM THE WARM AIR MOVING IN ON THE SOUTHWEST FLOW...MOST
PRECIPITATION WILL BE RAIN WITH A RAIN/SNOW MIX ABOVE 3000 FEET. THE
FRONT WILL PROGRESS INTO THE AREA TOMORROW AND SHOWERS WILL SPREAD
TO ALL LOCATIONS BY THE AFTERNOON AND BECOME HEAVIER OVERNIGHT.
WINDS WILL BE THE BIG STORY AS PRESSURE GRADIENTS WILL BE VERY
TIGHT. ALREADY HAVE A WIND ADVISORY OUT THROUGH TOMORROW AFTERNOON
FOR THE GRANDE RONDE VALLEY AND HAVE ISSUED ONE FOR THE BLUE
MOUNTAIN FOOTHILL ZONES FROM TONIGHT THROUGH TOMORROW AFTERNOON. AM
EXPECTING WINDS OF 25 TO 35 MPH WITH GUSTS TO 50 MPH LATE TONIGHT
THROUGH TOMORROW MORNING FOR THE FOOTHILLS WITH THE STRONGEST WINDS
CLOSEST TO THE BLUE MOUNTAINS IN PLACES LIKE PILOT ROCK AND MISSION.
THE REST OF THE AREA WILL BE BREEZY TO WINDY WITH 15 TO 25 MPH WINDS
COMMON. RIDGE TOPS IN THE MOUNTAINS WILL BE ANOTHER AREA WITH WINDS
OF 20 TO 30 MPH WITH HIGHER GUSTS. WITH THE STRONG SOUTHERLY WINDS
EXPECT ANOTHER RELATIVELY WARM NIGHT IN MUCH OF THE REGION SIMILAR
TO LAST NIGHT. TOMORROW WILL ALSO BE RELATIVELY WARM FOR THE SAME
REASONS. COOLER TEMPERATURES WILL RETURN TOMORROW NIGHT WHEN WINDS
DIE DOWN AND SHIFT TO THE WEST. PERRY

.LONG TERM...WEDNESDAY THROUGH SATURDAY NIGHT.  WET AND OCCASIONALLY
BREEZY/WINDY CONDITIONS WILL CONTINUE THROUGH THE END OF THE WEEK.
THE FORECAST AREA WILL REMAIN UNDER A W-SW FLOW ALOFT THROUGH
FRIDAY.  THERE WILL BE ABOUT A 6-12 HOUR BREAK IN PRECIPITATION ON
WEDNESDAY AS ONE SHORTWAVE TROUGH EXITS THE REGION BUT ANOTHER WILL
CLOSELY FOLLOW LATE WEDNESDAY AND WEDNESDAY NIGHT.  A MOIST SW FLOW
ALOFT WILL BRING RAIN AND MOUNTAIN SNOW WEDNESDAY NIGHT THROUGH
THURSDAY NIGHT. FORECASTING SNOW LEVELS HAS BEEN A CHALLENGE AS
THERE ARE NO STRONG ORGANIZED WARM FRONTS TO BRING SIGNIFICANT WARM
AIR ADVECTION. HOWEVER...AS THE PARENT TROUGH MOVES ACROSS WA/OR
FRIDAY THROUGH SATURDAY NIGHT...SNOW LEVELS WILL LOWER AND MAY BE
DOWN TO THE BASIN FLOOR SATURDAY NIGHT. ITS A LITTLE TOO EARLY TO
SAY...BUT THE TROUGH ON FRIDAY NIGHT AND SATURDAY COULD BRING
SIGNIFICANT SNOW TO THE MOUNTAINS.   WINDS WILL ALSO BE A CONCERN IN
THE EXTENDED PERIOD...PARTICULARLY IN THE GRANDE RONDE VALLEY... THE
BLUE MOUNTAIN FOOTHILLS...AND THE JOHN DAY BASIN THURSDAY AND
THURSDAY NIGHT.  JOHNSON

SUNDAY THROUGH MONDAY NIGHT...AN UPPER LEVEL DISTURBANCE WILL
CONTINUE TO PUSH ACROSS THE PACIFIC NORTHWEST PROVIDING A CHANCE FOR
RAIN AND SNOW SHOWERS SUNDAY. DRY NORTHWEST FLOW WILL SET IN BEHIND
THE DISTURBANCE SUNDAY NIGHT. WILL KEEP CHANCE SHOWERS IN THE
MOUNTAINS DUE TO UPSLOPE AND SLIGHT CHANCE SHOWERS ACROSS THE LOWER
ELEVATIONS.  THIS IS DUE TO MODELS STILL INDICATING LIGHT AMOUNTS OF
LINGERING QPF DURING THE TRANSITION. TEMPERATURES SHOULD WARM UP ON
MONDAY AS 500MB HEIGHTS INCREASE DUE TO THE UPPER LEVEL PATTERN
TRANSITIONS TO A LONGWAVE RIDGE. AS THIS TRANSITION OCCURS...FLOW
ALOFT WILL BE ZONAL...AND AT LEAST SLIGHT CHANCE OF SHOWER ACTIVITY
IS POSSIBLE MONDAY NIGHT. WEBER

&&

.AVIATION...00Z TAFS. THE BIGGEST AVIATION CONCERN FOR THE NEXT 24
HOURS WILL BE SURFACE WINDS.  WINDS WILL INCREASE TO AROUND
18-30G40KT OVERNIGHT AT KALW, KPDT, AND KRDM.  I DO NOT EXPECT AS
STRONG OF WINDS AT THE OTHER TAF SITES ALTHOUGH THERE COULD BE GUSTS
TO AROUND 30KT THROUGH EARLY TUESDAY MORNING.  WINDS WILL DIMINISH
TUESDAY AFTERNOON.  CIGS WILL LOWER THROUGH THE NIGHT  AND TUESDAY
MORNING BUT WILL KEEP VFR CONDITIONS UNTIL 18Z.  AFTER 18Z...THERE
IS A POTENTIAL FOR MVFR CONDITIONS OR LESS WITH -RA.  JOHNSON

&&

.HYDROLOGY...WITH THE REDUCED FLOOD STAGE AT CLIFFDELL, COMBINATION
OF SNOWMELT AND RAIN MAY ALLOW ALLOW THE RIVER TO EXCEED 750 CFS BY
TUESDAY MORNING. THERE ARE SEVERAL UNKNOWNS WITH THE FORECAST AS THE
STRENGTH OF THE WARM AIR AND THE ABILITY OF THE SNOWPACK TO ABSORB
THE RAIN AND THE TIMING OF THE COOLER AIR ON TUESDAY.  A WARNING FOR
THIS LOCATION WILL BE ISSUED.  ML
