AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
240 AM PST SUN JAN 16 2011

.SHORT TERM...TODAY THROUGH MONDAY NIGHT.  THE PRIMARY WEATHER
CONCERN IN THE SHORT TERM WILL BE HIGH WATER LEVELS ALONG THE RIVERS
AND STREAMS IN THE FORECAST AREA.  THE HYDROLOGY SECTION WILL
PROVIDE MORE DETAILS.  A VERY MOIST WARM FRONT WITH A SIGNIFICANT
MOISTURE PLUME OFF THE PACIFIC HAS BROUGHT WIDESPREAD RAIN WITH 24
RAINFALL AMOUNTS OF 0.5-1.0 INCH ALONG THE EAST SLOPES OF THE
CASCADES AND BLUE MOUNTAINS AND 0.25-0.5 OF AN INCH ELSEWHERE.  A
STEADY STREAM OF PACIFIC MOISTURE WILL CONTINUE TO BRING MODERATE TO
HEAVY RAIN OVER THE MOUNTAINS AIDED BY OROGRAPHIC LIFT. THE COLUMBIA
BASIN WILL SEE LIGHT TO MODERATE RAIN THE MORNING DECREASING THIS
AFTERNOON AND EVENING. A STRONG WESTERLY FLOW WILL PROVIDE RAIN
SHADOWING OFF THE CASCADES. THE DOWNSLOPE DRYING WILL TAKE PLACE
OVERNIGHT...AND RAIN WILL END THROUGHOUT THE COLUMBIA BASIN DOWN TO
CENTRAL OREGON.  RAIN WILL GRADUALLY TAPER OFF OVER THE MOUNTAINS
OVERNIGHT AFTER THE PASSAGE OF A SURFACE COLD FRONT.

WINDS ALOFT WILL INCREASE FROM THE NW OVERNIGHT AND MONDAY
MORNING...AND HIGH PRESSURE BUILDING BEHIND THE FRONT WILL RESULT IN
A TIGHT PRESSURE GRADIENT.  IT WILL BE BREEZY/WINDY THROUGHOUT THE
FORECAST AREA TONIGHT AND MONDAY MORNING (STRONG WINDS ALONG
RIDGETOPS).  A WIND ADVISORY WILL BE ISSUED FOR THE LOWER COLUMBIA
BASIN OF WASHINGTON TONIGHT UNTIL NOON ON MONDAY.  MAIN CONCERN WILL
BE THE HORSE HEAVEN HILLS AND NEAR HANFORD...AREAS THAT ARE WIND
PRONE TO STRONG SW WINDS AND SHOULD HAVE GUSTS IN THE 45-55 MPH
RANGE.  SHOWERS WILL CONTINUE OVER THE MOUNTAINS MONDAY...MAINLY
ALONG THE NW FACING SLOPES.  THE REST OF THE AREA WILL SEE LITTLE TO
NO PRECIPITATION.  ONLY A FEW LINGERING SHOWERS ARE EXPECTED MONDAY
NIGHT.  COOLER AIR WILL SPREAD EAST OF THE CASCADES MONDAY AND
MONDAY NIGHT...AND IT WILL BE QUITE A BIT COOLER MONDAY NIGHT
COMPARED TO THE UNSEASONABLY WARM TEMPERATURES WE HAVE EXPERIENCED
THE PAST SEVERAL DAYS.  JOHNSON

.LONG TERM...TUESDAY THROUGH SATURDAY...MODELS CONTINUE TO INDICATE
A RIDGE OF HIGH PRESSURE IN THE EAST PACIFIC AND A WEATHER
DISTURBANCE MOVING THROUGH THE NORTHWEST FLOW OVER THE FORECAST AREA
ON TUESDAY. MODELS DIFFER HOWEVER IN THE DETAILS OF HOW MUCH
PRECIPITATION WILL BE WITH THE SYSTEM. THE CASCADES AND MOUNTAINS OF
NORTHEAST OREGON HAVE THE BEST CHANCE FOR PRECIPITATION DUE TO THE
UPSLOPE FLOW...WHILE THE LOWER ELEVATIONS HAVE A LESSER CHANCE WITH
RAINSHADOWING. SNOW LEVELS WILL LOWER ACROSS THE REGION AS COLDER
AIR MOVES IN WITH THIS SYSTEM TUESDAY NIGHT INTO WEDNESDAY. THIS
WILL LEAD TO A CHANCE OF RAIN AND SNOW FOR THE ENTIRE AREA...THOUGH
THE BRUNT OF THE PRECIPITATION WILL BE EAST OF THE AREA BY TUESDAY
NIGHT EXCEPT IN FAVORABLE NORTHWEST UPSLOPE FLOW REGIONS. THE RIDGE
OF HIGH PRESSURE WILL SHIFT EAST AND BRING A DRY NORTHWEST FLOW TO
MOST OF THE AREA FOR WEDNESDAY AND THURSDAY. THE NEXT SYSTEM WILL
IMPACT THE AREA BY FRIDAY. THE EUROPEAN MODEL IS FASTER WITH THE
SYSTEM...BRINGING IT THROUGH THURSDAY NIGHT WHILE THE GFS BRINGS IT
THROUGH ON FRIDAY/FRIDAY NIGHT. HAVE A CHANCE OF PRECIPITATION FOR
THE HIGHER TERRAIN STARTING THURSDAY NIGHT DUE TO THE UNCERTAINTY OF
THE TIMING OF THE SYSTEM AND INCREASE THE CHANCES INTO FRIDAY AND
FRIDAY NIGHT WHEN BOTH MODELS INDICATE UNSETTLED FLOW OVER THE
REGION. THIS UNSETTLED PATTERN WILL CONTINUE INTO NEXT WEEKEND. DMH

&&

.AVIATION...12Z TAFS...FOG AND MIST WILL CONTINUE TO IMPACT KDLS AND
KYKM THROUGH THE MORNING HOURS AS ABUNDANT MOISTURE STREAMS INTO THE
REGION. THESE IFR TO LIFR CONDITIONS IN LOW CEILINGS AND
VISIBILITIES ARE EXPECTED TO IMPROVE LATER THIS MORNING. MVFR
CONDITIONS WITH THE RAIN WILL REMAIN POSSIBLE THROUGH THE
DAY...THOUGH VICINITY RAIN WILL END AT KYKM BY THE AFTERNOON. THE
REST OF THE FORECAST AREA WILL SEE A DECREASE IN RAIN COVERAGE THIS
EVENING AND OVERNIGHT AS THE WEATHER SYSTEM MOVES OFF TO THE EAST.
SURFACE WINDS WILL INCREASE THIS AFTERNOON ACROSS THE AREA WITH
KPSC...KYKM...KALW AND KPDT SEEING GUSTS 25 TO 35 KTS BY THE EVENING
HOURS AND 20 TO 25 KTS CAN BE EXPECTED ELSEWHERE. DMH

&&

.HYDROLOGY...THERE HAVE BEEN SHARP RISES ALONG MANY OF THE RIVERS
THE PAST 12 HOURS ASSOCIATED WITH RAIN AND SNOW MELT RUNOFF.  THE
KLICKITAT RIVER NEAR PITT IS JUST UNDER BANKFULL AND IS FORECAST TO
RISE ABOVE FLOOD STAGE BY NOON TODAY.  A FLOOD WARNING WAS ISSUED
FOR THE KLICKITAT RIVER...AND MINOR FLOODING IS EXPECTED.  FLOOD
WATCHES WERE ISSUED FOR THE WALLA WALLA RIVER NEAR TOUCHET AND THE
UMATILLA RIVER AT PENDLETON...AS LATEST FORECAST BRINGS LEVELS TO
FLOOD STAGE MONDAY AFTERNOON.  ADDITIONAL FLOOD WATCHES AND WARNINGS
MAY BE ISSUED FOR OTHER RIVERS IF LEVELS SHOULD SPIKE SUDDENLY.
SMALL STREAM FLOOD ADVISORIES REMAIN IN EFFECT FOR AREAS NEAR THE
EAST SLOPES OF THE WASHINGTON CASCADES.  JOHNSON
