&&
.AVIATION...06Z TAFS...VFR CONDITIONS WILL PERSIST DURING THE NEXT
24 HOURS. THE THUNDERSTORM THREAT HAS DIMINSHED...BUT WILL REDEVELOP
OVER CENTRAL TO NORTHEAST OREGON SATURDAY AFTERNOON. THE BEST CHANCE
FOR THUNDER WILL BE AT KRDM...WITH MOST STORMS REMAINING EAST OF
KPDT AND KALW. 76
&&
.HYDROLOGY...THE YAKIMA AND NACHES RIVER CONTINUE TO RUN HIGH DUE TO
SNOW MELT. A FLOOD WARNING FOR MINOR FLOODING ON THE NACHES AT
NACHES HAS BEEN ISSUED. THE RIVER IS AT 16.9 FEET AND EXPECTED TO
INCREASE ABOVE FLOOD STAGE OF 17.0 FEET BY MORNING. A FLOOD ADVISORY

CENTRAL KITTITAS COUNTY. DETAILS ON THIS CAN BE FOUND IN THE PRODUCT
PDXFLSPDT. A RIVER STATEMENT (PDXRVSPDT) CONTINUES FOR THE NACHES
RIVER NEAR CLIFFDELL AND THE YAKIMA RIVER AT UMTANUM. THESE RIVER

BELOW FLOOD STAGE AT THIS TIME.
&&
.PREV DISCUSSION... /ISSUED 425 PM PDT FRI MAY 29 2009/
SHORT TERM...HIGH PRESSURE WAS OVER N NEVADA AND PROVIDING OUR WARM
TEMPERATURES FOR TODAY. LATEST RADAR WAS SHOWING CONVECTION FIRING
ALONG THE SOUTHERN PORTIONS OF THE AREA AND EXTENDS NE INTO THE BLUE
AND WALLOWA MTNS. THIS IS IN RESPONSE TO ABOVE NORMAL TEMPS AND MID
LEVEL MOISTURE THAT WAS RAPPING AROUND THE HIGH AND INTO OUR AREA.
SOME OF THE STORMS MAY BECOME STRONG TODAY WITH THE THREAT OF HAIL A
POSSIBILITY MAINLY SOUTH OF THE OREGON/WA STATE LINE. THE GFS AND
NAM WERE IN AGREEMENT WITH KEEPING THE INSTABILITY OVER MOST OF THE
AREA OVERNIGHT. HOWEVER SOME DRIER AIR WORKS ITS WAY INTO PORTIONS
OF THE REGION FROM THE WEST AND INDICATED THIS IN THE FORECAST
OVERNIGHT.
BY SATURDAY MID LEVEL MOISTURE REMAINS OVER CENTRAL OREGON AND INTO
THE BLUES/WALLOWAS AND WILL LEAVE POPS IN THE FORECAST ACROSS THIS
AREA. ONCE AGAIN COMBINING THE MID LEVEL MOISTURE PLUME WITH ABOVE
NORMAL TEMPERATURES WILL PRODUCE AFTERNOON AND EVENING
THUNDERSTORMS. A SUBTLE COOL FRONT PASSING THROUGH THE AREA SATURDAY
NIGHT MAY LOWER AFTN TEMPERATURES SOME ON SUNDAY BUT THEY WILL STILL
REMAIN ABOVE NORMAL. MID LEVEL MOISTURE REMAINS OVER THE SOUTHERN
PORTIONS OF THE AREA THAT INCLUDES CENTRAL OREGON EASTWARD TO SENECA
AND THE BLUE/WALLOWA MTNS SUNDAY. THUS SHOWERS AND THUNDERSTORMS ARE
POSSIBLE ACROSS THIS AREA AGAIN.
LONG TERM...MONDAY THROUGH FRIDAY...MID RANGE DATA ARE NOW TRYING
TO CONVERGE ON A REX BLOCK TYPE SOLUTION AS THE PATTERN FOR THIS
PERIOD. AS SUCH WE WOULD SEE NORTHERLY FLOW ALOFT OVER THE NORTHERN
HALF OF THE PACNW WITH A CONVERGENT EASTERLY FLOW OVER CENTRAL AND
SOUTHERN OREGON. THUS CONDITIONS WOULD BE FAIR AND DRY ACROSS
WASHINGTON AND EXTREME NORTHERN OREGON WITH SHOWERS AND
THUNDERSTORMS POSSIBLE OVER CENTRAL OREGON. AT THIS TIME CONFIDENCE
REMAINS LOW AS TO WHETHER THIS PATTERN WILL INDEED FORM...ESPECIALLY
BEYOND MONDAY. AT THIS TIME WILL GO ALONG WITH THE REX BLOCK PATTERN
FOR MONDAY...AND HAVE INDICATED SLIGHT CHANCE SHOWERS AND/OR
THUNDERSTORMS OVER OUR CENTRAL OREGON ZONES AND DRIED OUT ALL OTHER
AREAS. FOR THE REMAINDER OF THE PERIOD ONLY SLIGHT CHANGES WERE
MADE TO THE CURRENT FORECASTS DUE TO THE CONTINUED UNCERTAINTY. 90
