AIDED BY A STRONG MID/UPPER LEVEL JET TO OUR SOUTH AND AN UNSTABLE ATMOSPHERE THUNDERSTORMS HAVE BEEN DEVELOPING IN THE MOUNTAINS OF CENTRAL AND EASTERN OREGON AND WILL CONTINUE TO DO SO THROUGH THE EVENING. THE TROUGH IS ALSO CREATING SOME TIGHT PRESSURE GRADIENTS ALONG THE EAST SLOPES OF THE CASCADES THIS AFTERNOON AND BREEZY TO WINDY CONDITIONS CAN BE EXPECTED IN THE COLUMBIA GORGE AND KITTITAS VALLEY THIS EVENING AND OVERNIGHT. OVERNIGHT THE THUNDERSTORMS WILL SLOWLY WIND DOWN AND TURN TO SCATTERED RAIN SHOWERS BY TOMORROW MORNING ALTHOUGH AN ISOLATED THUNDERSTORM OR TWO IS POSSIBLE IN THE NORTHERN BLUES AND WALLOWA COUNTY SO HAVE INCLUDED ISOLATED THUNDERSTORMS IN THE FORECAST FOR THOSE AREAS. TOMORROW AFTERNOON A SLIGHT CHANCE OF THUNDERSTORMS WILL FIRE UP ONCE AGAIN IN THE NORTHERN BLUES WITH A CHANCE OF THUNDERSTORMS IN WALLOWA COUNTY CLOSEST TO THE DEPARTING TROUGH. TEMPERATURES WILL WARM OVER THE WESTERN PORTION OF THE AREA TOMORROW AS AS THE COOLER AIR ASSOCIATED WITH THE TROUGH MOVES EAST WHILE THE EASTERN HALF OF THE AREA STILL UNDER THE COOL AIR WILL HAVE A REPEAT OF TODAYS TEMPERATURES. WALLOWA COUNTY WILL FINALLY SEE AN END TO THUNDERSTORMS TOMORROW EVENING. AFTER THAT...RIDGING WILL BEGIN BUILDING INTO THE AREA FOR DRY WEATHER AND A WARMING TREND FOR THE REMAINDER OF THE SHORT TERM PERIOD. PERRY .LONG TERM...SATURDAY THROUGH WEDNESDAY...AN UPPER LEVEL RIDGE WILL BUILD OVER THE REGION ON SATURDAY. SUBSIDENCE FROM THE RIDGE WILL KEEP THE AREA DRY WITH INCREASING TEMPERATURES THROUGH SUNDAY. THE RIDGE WILL WEAKEN SUNDAY AFTERNOON EVENING AND MONDAY NIGHT/TUESDAY AS WEAK WAVES MOVE THROUGH...BUT TIMING HAS BEEN INCONSISTENT. CONFIDENCE IS LOW IN TIMING...STRENGTH...AND MOISTURE WITH BOTH SYSTEMS. INSTABILITY AND MOISTURE WILL BE LIMITED. THUNDERSTORM PARAMETERS ARE MARGINAL OVER CENTRAL TO NORTHEAST OREGON SUNDAY. SINCE THERE IS UNCERTAINTY IN TIMING AND LIMITED MOISTURE/INSTABILITY LEFT CURRENT FORECAST DRY SUNDAY. MONDAY NIGHT AND TUESDAY ANOTHER WAVE WILL MOVE THROUGH THE RIDGE AND PUMP MORE MOISTURE AND UNSTABLE AIR OVER THE AREA. MOISTURE WILL REMAIN LIMITED AND OVERNIGHT TIMING WILL NOT ENHANCE CONVECTION...SO I DO NOT EXPECT ANY THUNDERSTORMS WITH IT. THIS SYSTEM WILL KEEP TEMPERATURES A FEW DEGREES COOLER TUESDAY. THE RIDGE WILL REBUILD OVER EASTERN WASHINGTON AND OREGON TUESDAY NIGHT AND WEDNESDAY. COONFIELD && .AVIATION...VFR CONDITIONS WILL PERSIST THROUGH THE NEXT 24 HOURS.

MVFR CONDITIONS MAY OCCUR BRIEFLY NEAR THE THUNDERSTORMS DUE TO LOCALLY MODERATE TO HEAVY RAIN AND LOWER CEILINGS.
