...WIND ADVISORY IS CANCELLED...

THE NATIONAL WEATHER SERVICE IN PENDLETON HAS CANCELLED THE WIND
ADVISORY. 

SURFACE PRESSURE GRADIENTS ARE WEAKENING NOW AND THIS IS ALLOWING
THE WIND TO DIMINISH ACROSS THE KITTITAS VALLEY AS WELL AS OTHER
AREAS OF THE LOWER COLUMBIA BASIN AND ADJACENT VALLEYS. AS SUCH
THE WIND ADVISORY FOR THE KITTITAS VALLEY HAS BEEN CANCELLED AND
WIND ADVISORIES IN OTHER AREAS ARE NOT NEEDED.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
1033 PM PDT MON JUN 6 2011

CHANGED THREAT INDEX TO YELLOW FOR TONIGHT AND TUESDAY

.UPDATE...THE UPPER LOW PRESSURE SYSTEM THAT IS BRINGING RAIN TO
SOME PORTIONS OF THE FORECAST AREA HAS NOW MOVED TO SOUTHERN IDAHO.
THE WRAP AROUND FLOW IS PULLING MOISTURE DOWN FROM THE NORTH INTO
NORTHERN AND EASTERN AREAS WHILE THE SOUTHERN AND WESTERN AREAS HAVE
JUST A FEW LIGHT SHOWERS. THERE ARE ALSO A FEW THUNDERSTORMS...BUT
THEY ARE WEAK AND ONLY PRODUCING SOME LIGHTNING AND POSSIBLY BRIEF
HEAVY RAIN. ONE FACTOR IN THE FORECAST IS THE WIND IN THE KITTITAS
VALLEY WHICH ROSE TO NEAR ADVISORY LEVELS THIS EVENING AND MAY
EXCEED ADVISORY SPEEDS FOR BRIEF PERIODS BEFORE THE EVENING IS OVER.
HOWEVER...AM NOT EXPECTING THAT TO HAPPEN...BUT WILL NEED TO WATCH
IT. THE MAIN CONCERNS ARE VARIOUS FLOOD WATCHES AND WARNINGS IN
EFFECT INCLUDING EXPECTED FLOODING ON THE NACHES RIVER NEAR NACHES
AND AND AREAL FLOOD WARNING FOR THE EASTERN BLUE MOUNTAINS AS WELL
AS THE GRANDE RONDE VALLEY AND WALLOWA COUNTY. THERE IS ALSO A FLOOD
WATCH FOR THE SOUTHERN BLUE MOUNTAINS AND ALSO THE JOHN DAY
HIGHLANDS AND THE JOHN DAY BASIN. SO FAR PRECIPITATION HAS BEEN
LIGHT THERE. WITH THE PRECIPITATION MOVING TO THE EAST WITH THE
UPPER LOW AM NOT EXPECTING MUCH THERE IN THE WAY OF RAINFALL. MAY BE
ABLE TO CANCEL THE FLOOD WATCH FOR THOSE AREAS. COOLER TEMPERATURES
WITH BREEZY TO WINDY CONDITIONS ARE EXPECTED ON TUESDAY AND
WEDNESDAY. ANY FORECAST UPDATES WILL BE MADE LATER THIS EVENING. 88

&&

.AVIATION...06Z TAFS...VFR CONDITIONS ARE EXPECTED AT ALL TAF SITES
OVERNIGHT AND ON TUESDAY. THERE MAY BE A FEW SHOWERS...ESPECIALLY AT
KPDT...KALW...KRDM AND KBDN. HOWEVER...CEILINGS AND VISIBILITY
SHOULD STAY IN THE VFR RANGE THROUGH TUESDAY EVENING. ELSEWHERE IT
SHOULD REMAIN MOSTLY DRY TONIGHT THROUGH TUESDAY EVENING. WINDS OF
20 TO 30 KTS WILL BE A CONCERN NEAR KDLS THIS EVENING AND ON
TUESDAY. WINDS WILL ALSO INCREASE TO 15 TO 25 MPH AT
KPDT...KALW...KRDM AND KBDN ON TUESDAY...IF NOT TONIGHT. 88

&&

.PREV DISCUSSION... /ISSUED 328 PM PDT MON JUN 6 2011/

SHORT TERM...TONIGHT THROUGH THURSDAY...MOISTURE IS STREAMING INTO
EASTERN OREGON FROM AN UPPER LEVEL LOW OVER NEVADA. A DEFORMATION
BAND HAS FORMED OVER UNION AND WALLOWA COUNTIES WITH INCREASING
PRECIPITATION. A FEW LIGHTNING STRIKES HAVE OCCURRED NORTH OF GOLDEN
DALE AND BICKLETON IN KLICKITAT COUNTY...BAKER COUNTY...AND WALLOWA
COUNTY. EXPECT CLOUD COVER AND LIMITED INSTABILITY TO KEEP
THUNDERSTORM COVERAGE ISOLATED. AS THE UPPER LOW MOVES NORTHEAST
OVERNIGHT EXPECT MODERATE TO HEAVY RAIN TO DEVELOP IN WALLOWA
COUNTY...GRANDE RONDE VALLEY...EASTERN GRANT COUNTY...AND THE
NORTHERN BLUES...WITH LIGHTER AMOUNTS FARTHER WEST IN WESTERN GRANT
COUNTY...AND THE SOUTHERN BLUES. PRECIPITATION WILL DIMINISH
TUESDAY AS WEAK RIDGING DEVELOPS IN CENTRAL OREGON AND WASHINGTON
BEHIND THE LOW. A FEW SHOWERS WILL PERSIST OVER THE NORTHEAST OREGON
MOUNTAINS AND EXTREME SOUTHEAST WASHINGTON. AT THE SAME TIME A
MARINE PUSH WITH GRADIENT DRIVEN WINDS WILL BRING BREEZY TO WINDY
CONDITIONS IN THE LOWER COLUMBIA BASIN...COLUMBIA RIVER GORGE...AND
KITTITAS VALLEY. WINDS MAY APPROACH WIND ADVISORY CRITERIA IN THE
GORGE AND KITTITAS VALLEY...BUT NOT ENOUGH CONFIDENCE TO ISSUE ONE
YET. ANOTHER UPPER LEVEL LOW WILL MOVE FROM NORTHWEST WASHINGTON
TUESDAY NIGHT INTO WALLOWA COUNTY WEDNESDAY AFTERNOON. THIS WILL
BRING ANOTHER ROUND OF SHOWERS. A FEW THUNDERSTORMS ARE POSSIBLE
WEDNESDAY AFTERNOON NEAR THE LOW IN WALLOWA AND UNION COUNTIES. A
FEW SHOWERS WILL LINGER OVER GRANT COUNTY AND NORTHEAST OREGON
THURSDAY.   COONFIELD

LONG TERM...THURSDAY EVENING THROUGH TUESDAY...MODELS HAVE BEEN
BACK AND FORTH WITH THE EXTENDED PERIOD. A WEAK DISTURBANCE LOOKS TO
PUSH ACROSS NORTHERN WASHINGTON THURSDAY INTO FRIDAY. THERE IS A
SLIGHT CHANCE FOR THUNDER FRIDAY AFTERNOON ACROSS THE NORTHEASTERN
ZONES. MOST OF THE MOISTURE ASSOCIATED WITH THIS SYSTEM SHOULD STAY
TO THE NORTH...KEEPING THE LOWER COLUMBIA BASIN AND THE FOOTHILLS OF
THE BLUE MOUNTAINS DRY. SPILL OVER SHOWERS ARE POSSIBLE ALONG THE
EAST SLOPE OF THE CASCADES FRIDAY. NORTHWEST FLOW CONTINUES TO
PREVAIL FOR THE EXTENDED AS WEAK DISTURBANCES CONTINUE TO STAY NORTH
OF THE AREA. TEMPERATURES STILL STAY FAIRLY MILD FOR THIS TIME OF
YEAR. THE EUROPEAN MODEL HAS HINTED AT THE POSSIBILITY OF AN UPPER
LEVEL RIDGE TO BUILD IN LATE TUESDAY. WEBER
