STRONG THUNDERSTORMS SKIRTED COLUMBIA AND WALLOWA COUNTIES EARLIER TONIGHT. THE THREAT OF SEVERE THUNDERSTORMS HAS ENDED BUT ISOLATED THUNDERSTORMS MAY OCCUR IN WALLOWA COUNTY AND CENTRAL OREGON. FLOOD WATCH REMAINS IN EFFECT FOR MOST OF NORTHEAST OREGON. THERE WERE 4 REPORTS OF .5 TO .6 INCH IN THE GRANDE RONDE VALLEY. OVER .5 INCH HAS FALLEN AT MEACHAM AND MEACHAM LAKE.

WINDS WILL INCREASE FURTHER AT KDLS EASTWARD THROUGH KPDT AND KALW ON TUESDAY WITH 15 TO 25 KT AND GUSTS TO 30KTS. 76 && .PREV DISCUSSION... /ISSUED 244 PM PDT MON JUN 4 2012/ SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT...THE UPPER TROUGH OFF THE WEST COAST CONTINUES TO DIG SOUTHEAST, BECOMING NEGATIVELY TILTED. THIS SYSTEM HAS BEEN PUSHING CONSIDERABLE AMOUNTS OF MOISTURE INTO THE REGION. A BAND OF STEADY RAIN NOW EXTENDS FROM CROOK AND WESTERN GRANT COUNTIES NORTH INTO THE COLUMBIA BASIN. NUMEROUS SHOWERS ARE OCCURRING WEST AND EAST OF THIS BAND. THUNDERSTORMS HAVE ALSO DEVELOPED OVER EXTREME EASTERN GRANT COUNTY INTO UNION COUNTY. THE POTENTIAL FOR STRONG, OR EVEN SEVERE STORMS, CONTINUES TO EXIST. THE BEST CHANCES OF STRONG OR SEVERE STORMS WILL BE OVER UNION AND WALLOWA COUNTIES IN OREGON AND COLUMBIA COUNTY IN WASHINGTON WHERE DAYTIME HEATING WAS THE STRONGEST. A SEVERE THUNDERSTORM WATCH IS IN EFFECT FOR THESE COUNTIES. EXPECT THIS THUNDERSTORM THREAT TO WIND DOWN THROUGH EARLY EVENING AS THE PERSISTENT RAIN BAND SHIFTS EAST INTO THESE AREAS. WILL DROP GRANT COUNTY FROM THE WATCH BY 3 PM. STRAY THUNDERSTORMS MAY BE POSSIBLE FROM CENTRAL GRANT COUNTY NORTH INTO THE BLUE MOUNTAIN FOOTHILLS, THOUGH THESE AREAS ARE LOOKING TO BECOME TOO STABILIZED FOR THUNDER. A FEW COLD CORE STORMS HAVE DEVELOPED OVER SOUTHWEST OREGON NEAR AN UPPER LEVEL WAVE. THESE STORMS SHOULD DRIFT INTO DESCHUTES AND CROOK COUNTIES LATE THIS AFTERNOON AND THIS EVENING. THESE STORMS MAY DRIFT TO SOUTHERN GRANT COUNTY OVERNIGHT. OVERNIGHT THE PERSISTENT RAIN BAND WILL SLOWLY MOVE THROUGH OUR NORTHEASTERN MOST ZONES. PRECIP TOTALS, ESPECIALLY IN BLUE AND WALLOWA MOUNTAINS, MAY APPROACH AN INCH. THIS COULD RESULT IN A SIGNIFICANT INCREASE IN RUNOFF RAISE STREAM LEVELS. THUS A FLOOD WATCH IS IN EFFECT THROUGH TUESDAY. THE UPPER TROUGH WILL SWING ACROSS THE REGION TUESDAY. THUS SHOWERS WILL CONTINUE OVER OUR EASTERN ZONES, BUT THE SHOWERS SHOULD BECOME MORE SCATTERED ELSEWHERE ON TUESDAY. WINDS WILL BECOME BREEZY TONIGHT INTO TUESDAY. SNOW LEVELS WILL LOWER TO 4500 TO 5000 FEET ON TUESDAY. THUS SOME LIGHT ACCUMULATIONS WILL BE POSSIBLE ABOVE THESE LEVELS. DRIER WESTERLY FLOW WILL SPILL INTO THE REGION TUESDAY NIGHT THROUGH WEDNESDAY. THIS WILL CAUSE A GRADUAL, BUT CONTINUOUS DECREASE IN SHOWERS AREA WIDE. ANOTHER PACIFIC SYSTEM MAY PUSH SOME LIGHT RAIN INTO CENTRAL OREGON AND WASHINGTON BY EARLY THURSDAY MORNING. 90 LONG TERM...THURSDAY THROUGH MONDAY. ON THURSDAY..THE NEXT IN THE SERIES OF LOWS MOVES TO 130W WITH SOUTHWEST FLOW ACROSS THE REGION. THIS LOW MOVES ONTO THE WASHINGTON COAST ON FRIDAY MORNING AND THEN SLOWLY TRACKS ACROSS OREGON AND WASHINGTON THROUGH SATURDAY. THIS SYSTEM WILL BRING IN ANOTHER ROUND OF RAIN WITH SOME THUNDERSTORMS FOR POSSIBLE SATURDAY AFTERNOON AND EVENING WITH THE COLD UPPER LOW ON TOP OF THE REGION. TEMPERATURES WILL BE QUITE COOL THROUGH THE REST OF THE WEEK AS WELL WITH HIGHS ON THURSDAY AND FRIDAY ABOUT 10 DEGREES BELOW NORMAL. ON SUNDAY...THE COOL NORTHWEST FLOW CONTINUES OVER THE AREA...BUT MAY SEE SOME SHOWERS OVER THE FAR NORTHEAST MOUNTAINS AS THE MOISTURE WRAPS BACK AROUND THE LOW.
