AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
240 AM PDT WED JUN 29 2011

.SHORT TERM...TODAY THROUGH FRIDAY...SHOWERS ARE MAINLY IMPACTING
WALLOWA COUNTY THIS MORNING...BUT COVERAGE WILL INCREASE TODAY AS
ADDITIONAL MOISTURE IS PUSHED NORTHWARD BY THE LOW IN NORTHERN
CALIFORNIA. THE BEST CHANCES FOR PRECIPITATION WILL BE FROM GRANT
COUNTY NORTHEASTWARD THROUGH THE BLUE MOUNTAINS AND INTO UNION AND
WALLOWA COUNTIES. ALTHOUGH WIND SHEAR VALUES HAVE DECREASED THE
ATMOSPHERE WILL REMAIN UNSTABLE ENOUGH TO ALSO SUPPORT ISOLATED
THUNDERSTORMS. WHILE SEVERE STORMS ARE NOT EXPECTED ANY STORMS THAT
DO DEVELOP COULD PRODUCE SMALL HAIL AND/OR GUSTY WINDS. SHOWERS WILL
TAPER OFF OVERNIGHT BUT WESTERLY UPSLOPE FLOW COULD ALLOW A FEW TO
CONTINUE OVER THE BLUE AND WALLOWA MOUNTAINS THROUGH THURSDAY.

WIND IS ALSO A CONCERN TODAY AND THURSDAY. A MARINE PUSH ASSOCIATED
WITH THE TROUGH THAT IS COMING IN FROM THE NORTHWEST WILL TIGHTEN
SURFACE PRESSURE GRADIENTS. MODEL GUIDANCE HAS BEEN QUESTIONABLE BUT
THERE IS A GOOD CHANCE THAT THE KITTITAS VALLEY WILL SEE VERY WINDY
CONDITIONS TODAY. HAVE THEREFORE ISSUED A WIND ADVISORY FOR THIS
AFTERNOON AND EVENING. WINDS MAY AGAIN REACH ADVISORY LEVELS ON
THURSDAY AFTERNOON BUT HAVE DECIDED TO HOLD OFF ON ISSUING THE
ADVISORY FOR NOW. IF WINDS DO NOT BLOW ABOVE 30 MPH TODAY...THEN
THEY ARE NOT LIKELY TO DO SO ON THURSDAY. WINDY TO VERY WINDY
CONDITIONS CAN ALSO BE EXPECTED IN THE EASTERN COLUMBIA RIVER GORGE
BUT CONFIDENCE IS NOT HIGH ENOUGH TO ISSUE AN ADVISORY. BREEZY TO
LOCALLY WINDY CONDITIONS WILL OCCUR ACROSS THE REMAINDER OF THE
AREA...THUS PATCHY BLOWING DUST COULD BECOME A PROBLEM IN THE LOWER
COLUMBIA BASIN.

ZONAL FLOW WILL SET IN ON THURSDAY AFTERNOON BEHIND THE DEPARTING
LOW...THEREFORE MUCH DRIER CONDITIONS CAN BE EXPECTED INTO FRIDAY.
THE MARINE PUSH WILL BRING COOLER AIR INTO THE REGION TODAY AND
ESPECIALLY ON THURSDAY. AFTERNOON TEMPERATURES WILL THEN WARM BACK
INTO THE UPPER 70S AND LOWER 80S ON FRIDAY.  TRIMARCO

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY. ALTHOUGH A WEAK
DISTURBANCE MAY BRUSH THE WASHINGTON CASCADE CREST AND MOVE INTO THE
BLUE MOUNTAINS SUNDAY...MOSTLY DRY CONDITIONS SHOULD PERSIST THROUGH
THE WEEKEND. AFTERWARDS MID LEVEL HEIGHTS INCREASE WHICH SHOULD
CONTINUE THE DRY CONDITIONS FOR MONDAY AND TUESDAY WITH ABOVE NORMAL
TEMPERATURES EXPECTED.

&&

.AVIATION...12Z TAFS...LOW PRESSURE TO OUR SOUTH WILL CONTINUE TO
PUMP MOISTURE INTO OUR AREA TODAY POSSIBLY PRODUCING LCL MVFR
CEILINGS THIS AFTERNOON AND EVENING MAINLY ACROSS TAF SITES
KRDM...KPDT...KALW AFT 20Z. OTHERWISE OCCASIONAL BREEZY WINDS MAY
CREATE SOME BLOWING DUST AROUND TAF SITE KPSC THIS AFTERNOON AND TAF
