AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PENDLETON OR 1110 AM PDT MON JUN 12 2006 UPDATED FOR AVIATION DISCUSSION .SHORT TERM...PERSISTENT SOUTH FLOW ASSOCIATED WITH AN UPPER TROUGH ALONG THE WEST COAST CONTINUES TO KEEP A MOIST AND UNSTABLE AIR MASS OVER THE PACNW. A WAVE IMBEDDED WITHIN THE FLOW OVER NORTHERN CALIFORNIA AND NEVADA WILL MOVE NORTH ACROSS EASTERN OREGON AND WASHINGTON TODAY AND THIS EVENING. THUS EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP OVER MOST OF THE AREA LATE THIS MORNING THROUGH THIS EVENING. SHEAR AND UPPER DIFFLUENCE DOES SUPPORT THE DEVELOPMENT OF SOME ORGANIZED CONVECTIVE CELLS THIS AFTERNOON. THUS A FEW STORMS COULD BE SEVERE...WITH WIND GUSTS BEING THE MAIN CONCERN. ALSO BRIEF PERIODS OF HEAVY RAIN CAN BE EXPECTED AT LOCATIONS WHERE THE CENTERS OF SHOWERS AND THUNDERSTORMS MOVE OVERHEAD. UPDATES THIS MORNING HAVE BEEN TO SLIGHTLY ALTER COVERAGE WORDING OF CONVECTION THIS AFTERNOON...AND TO ADD MENTION OF THUNDERSTORMS FOR A FEW ZONES THIS MORNING. ALSO HAVE NUDGED POPS UP TO THE MID TO UPPER SCATTERED RANGE. 90 .LONG TERM...PREVIOUS DISCUSSION...AN UPPER LOW PRESSURE SYSTEM ALONG THE COAST WILL BEGIN TO MOVE INLAND TUESDAY NIGHT AND ON WEDNESDAY. WITH THIS UPPER LOW PRESSURE SYSTEM IS AN ABUNDANT AMOUNT OF MOISTURE AND INSTABILITY. 24 HOUR GFS FORECASTED QPF VALUES ENDING AT 12Z WEDNESDAY ARE OVER AN INCH OF RAIN OVER THE BLUE MOUNTAINS WITH LESS ELSEWHERE. PRECIP WATER VALUES ARE ALSO VERY JUICY AND OVER AN INCH OVER MOST OF THE FORECAST AREA. AS THE COLD POOL ALOFT WITH THE UPPER LOW PRESSURE MOVES INLAND WITH THE LOW ITSELF IT WILL KEEP THE ATMOSPHERE UNSTABLE THROUGH THE NIGHT TUESDAY NIGHT RESULTING IN A CONTINUED CHANCE OF SHOWERS AND EVENING THUNDERSTORMS...WITH MORE NUMEROUS SHOWERS OVER THE NORTHERN BLUE MOUNTAINS. THEN AS THE UPPER LOW CONTINUES TO SLOWLY MOVE EASTWARD ON WEDNESDAY SURFACE WESTERLY PRESSURE GRADIENTS WILL INCREASE ALONG THE CASCADE EAST SLOPES AND ADJACENT VALLEYS RESULTING IN THE FLOW BECOMING MORE DOWN SLOPE AND DRYER OFF THE CASCADES. THEREFORE THE COVERAGE OF SHOWERS WILL DECREASE ON WEDNESDAY FROM THE WEST WITH THE ATMOSPHERE BECOMING MORE STABLE THERE. FOR THE EXTENDED RANGE FORECAST PERIOD...A WEAK UPPER RIDGE WILL BUILD OVER THE REGION ON THURSDAY. HOWEVER THIS WILL BE SHORT LIVED AS ANOTHER WEAK WEATHER SYSTEM MOVES ACROSS THE REGION THURSDAY NIGHT AND FRIDAY. THE AMOUNT OF MOISTURE WITH THAT SYSTEM IS NOT TOO IMPRESSIVE AT THIS TIME... BUT WILL MENTION A SLIGHT CHANCE OF SHOWERS...MAINLY OVER THE MOUNTAINS. AFTER THAT A DRY WESTERLY FLOW WILL DEVELOP AND PERSIST FOR THE REMAINDER OF THE WEEK INTO NEXT WEEKEND. TEMPERATURES WILL REMAIN NEAR NORMAL THROUGH THE PERIOD. .AVIATION...VFR CONDITIONS WILL GENERALLY PREVAIL FOR THE NEXT 24 HOURS. MVFR OR EVEN IFR CONDITIONS MAY BE ENCOUNTERED AT TIMES THIS AFTERNOON AND EVENING AT ALL TAF SITES AND ON ALL TWEB ROUTES AS SCATTERED RAIN SHOWERS AND THUNDERSTORMS PRODUCE LOW CEILINGS AND VISIBILITY IS RESTRICTED BY HEAVY PRECIPITATION. GUSTY SURFACE WINDS MAY OCCUR AT ALL TAF LOCATIONS DUE TO THE SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING. MORE RAIN SHOWERS AND THUNDERSTORMS MAY CREATE SIMILAR CONDITIONS AGAIN LATE TOMORROW MORNING. 83 && .HYDROLOGY...PREVIOUS DISCUSSION...THE NACHES RIVER IN YAKIMA COUNTY CONTINUES TO RUN HIGH. OVER THE NEXT COUPLE OF DAYS THE RIVER... OVERALL...IS EXPECTED TO CONTINUE FALLING WITH MINOR RISES IN RIVER LEVELS POSSIBLE DUE TO RUNOFF FROM DAYTIME SNOWMELT AND/OR RAINFALL RUNOFF. HOWEVER...DESPITE ANY RISES THE RIVER WILL REMAIN BELOW FLOOD STAGE. PEOPLE ALONG THE NACHES RIVER ARE STILL URGED TO BE CAUTIOUS OF FAST MOVING WATER AS THE CURRENT COULD BE UNDERESTIMATED AND IS STILL DANGEROUS. && .PRELIMINARY POINT TEMPS/POPS...
