AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
250 AM PDT SUN JUN 17 2012
.SHORT TERM...TODAY THROUGH TUESDAY...A WEATHER SYSTEM WILL MOVE
ACROSS THE FORECAST AREA TODAY. CURRENTLY THERE ARE SOME RAIN
SHOWERS OVER THE BLUE MOUNTAIN FOOTHILLS AND THE EXTREME EASTERN
COLUMBIA BASIN AS WELL AS THE CWA'S NORTHEAST MOUNTAINS. THESE
SHOWERS ARE VERY LIGHT AND LITTLE ACCUMULATION IS EXPECTED IF ANY.
MAIN CONCERN TODAY WILL BE INCREASING WINDS BEHIND THE COLD FRONT
THAT IS CURRENTLY MOVING ACROSS THE EASTERN FORECAST AREA. THESE
WINDS WILL BE STRONGEST IN BOTH THE OREGON NORTHERN AND SOUTHERN
BLUE MOUNTAIN FOOTHILLS AND IN THE KITTITAS VALLEY. HAVE DECIDED TO
ISSUE A WIND ADVISORY FOR THESE LOCATIONS FROM 18Z-06Z THIS
AFTERNOON AND THIS EVENING. IN ADDITION TO THE WIND THERE WILL BE
PATCHY BLOWING DUST ACROSS MOST OF THE LOWER COLUMBIA BASIN AND THE
ADJACENT VALLEYS. SINCE RAINFALL IS EXPECTED TO BE VERY LIGHT THERE
WILL BE BLOWING DUST IN THOSE AREAS TOO...ESPECIALLY NEAR FRESHLY
PLOWED FIELDS. THIS SYSTEM WILL EXIT THE REGION TONIGHT AND BE
REPLACED BY A DRY AND STABLE NORTHWEST FLOW TONIGHT AND EARLY
MONDAY...WITH MUCH COOLER TEMPERATURES. MEANWHILE ANOTHER UPPER
TROUGH WILL BE DROPPING SOUTHEAST ALONG THE BC COAST AND WILL MOVE
INLAND AND ACROSS THE FORECAST AREA AND PACIFIC NORTHWEST BEGINNING
MONDAY AFTERNOON. THIS SYSTEM LOOKS TO BE A LITTLE STRONGER AND WILL
PROBABLY BRING A BETTER CHANCE OF SHOWERS ACROSS THE NORTHERN AREAS
OF THE CWA AND ALSO THE MOUNTAINS INCLUDING THE CASCADE EAST SLOPES.
THERE WILL BE SOME INSTABILITY WITH THIS NEXT SYSTEM AND CANNOT RULE
OUT A THUNDERSTORM OR TWO FOR EXTREME EASTERN AREAS SUCH AS THE
ELKHORN MOUNTAINS AND THE WALLOWA COUNTY AREA FOR MONDAY AND
TUESDAY. HOWEVER...ANY THUNDERSTORMS WILL NOT BE TOO WIDESPREAD.
THIS NEXT SYSTEM WILL EXIT THE REGION BY TUESDAY NIGHT AND DURING
THE EARLY PART OF THE EXTENDED FORECAST PERIOD. 88
.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...A RIDGE OF HIGH PRESSURE
WILL BUILD OVER THE AREA FOR THE MID TO LATE WEEK WITH WARMING
TEMPERATURES AND DRYING CONDITIONS. THE WARMEST DAY OF THE WEEK WILL
BE ON THURSDAY WITH HIGH TEMPERATURES WELL INTO THE 80S LOWER
ELEVATIONS. BY THE END OF THE WEEK AN UPPER LEVEL LOW PRESSURE OFF
THE COAST WILL BEGIN TO IMPINGE ON THE RIDGE AND BREAK IT DOWN. THIS
WILL RESULT IN STRENGTHENING S-SWLY FLOW WHICH WILL HELP TO MOISTEN
THE LOWER ATMOSPHERE. THUS...THERE WILL BE AT LEAST A SLIGHT CHANCE
FOR SHOWERS FRIDAY THROUGH SUNDAY AND COOLER TEMPERATURES. BEST
CHANCE FOR THUNDERSTORMS APPEARS TO BE ON FRIDAY BUT DIFFERENCES IN
TIMING IN THE MEDIUM RANGE MODELS PRECLUDES INCLUSION IN THE
FORECAST AT THIS TIME. 78
&&
.AVIATION...12Z TAFS...VFR CONDITIONS WILL PREVAIL THROUGH 12Z
MONDAY. A LITTLE LIGHT RAIN WILL BE IN THE VCNTY KPDT AND KALW THIS
MORNING OTHERWISE EXPECT DRY CONDITIONS AND DECREASING CLOUD COVER
TODAY. THE WINDS WILL BE THE PRIMARY CONCERN WITH WEST WINDS OF
20-30KT WITH HIGHER GUSTS EXPECTED THROUGH EARLY THIS EVENING BEFORE
DIMINISHING SOMEWHAT OVERNIGHT. WINDS WILL PEAK BETWEEN 23-02Z LATE
THIS AFTERNOON/EARLY EVENING. 78
