NORTHEAST OREGON/SOUTHEAST WASHINGTON FORECAST DISCUSSION NATIONAL WEATHER SERVICE PENDLETON OR 215 PM PDT TUE AUG 5 2003 STRONG CONVECTION DEVELOPING AHEAD OF A DISTURBANCE LOCATED OVER SOUTHWEST OREGON WILL CONTINUE TO MOVE NORTH THROUGH OUR WESTERN CWA OVERNIGHT. LIFT AND INSTABILITY AHEAD OF THIS SYSTEM WILL CONTINUE TO AID IN THE PRODUCTION OF STRONG THUNDERSTORMS THROUGH THIS EVENING...SOME WILL LINGER THROUGHOUT THE NIGHT OVER PORTIONS OF THE MOUNTAINS. INSTABILITY WILL CONTINUE OVER THE MOUNTAINS AS THE MAIN TROUGH ANCHORS ITSELF OVER THE EASTERN PACIFIC. AS A RESULT...ISOLATED MOUNTAIN THUNDERSTORMS ARE EXPECTED TO REDEVELOP EACH AFTERNOON THROUGH FRIDAY AS WEAK DISTURBANCES ROTATE AROUND THE MAIN LOW. TEMPERATURES ARE EXPECTED TO STAY NEAR NORMAL. EXTENDED...UPPER TROUGH TO REMAIN OVER THE EASTERN PACIFIC WITH A SOUTHWEST FLOW CONTINUING OVER THE PACIFIC NORTHWEST INTERIOR THROUGH THE WEEKEND. THERE SHOULD BE ENOUGH LINGERING MOISTURE FOR THE DEVELOPMENT OF A FEW SHOWERS OR THUNDERSTORMS FRIDAY. STILL APPEARS THAT LOW LEVEL ONSHORE FLOW WILL STRENGTHEN OVER THE WEEKEND. THIS WOULD RESULT IN THE AIR MASS OVER OUR CWA TO STABILIZE WITH NO SHOWERS AND THUNDERSTORMS EXPECTED. MID RANGE MODELS ARE PROVIDING SOME VARIANCE IN SOLUTIONS...BUT SUPPORT CONTINUES FOR THE UPPER TROUGH TO SLOWLY DRIFT EAST-SOUTHEAST EARLY NEXT. IF THE TROUGH DOES DRIFT INLAND...THIS COULD LEAD TO A RETURN TO A LOW CHANCE OF SHOWERS OR THUNDERSTORMS MONDAY AND TUESDAY OVER THE MOUNTAINS. GKH PDT 4--- ALW 4--- PSC 3--- YKM 3--- .KPDT...NONE.
