AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
935 AM PDT FRI SEP 21 2012

.UPDATE...HIGH PRESSURE CONTINUES TO DOMINATE THE AREAS WEATHER WITH
DRY CONDITIONS AND ABOVE NORMAL TEMPERATURES. SMOKE FROM SURROUNDING
FIRES HAVE SETTLED ACROSS THE NORTHERN AND EASTERN HALF OF OUR AREA
THAT HAS PROMPTED A AIR QUALITY ALERT THAT WILL BE EXPANDED INTO
THIS WEEKEND. THIS INCLUDES THE YKM/KITTITAS VALLEYS OF WASHINGTON
ALONG WITH THE COLUMBIA BASIN AND FOOTHILLS OF THE BLUE MOUNTAINS
INTO OREGON. UNION AND WALLOWA COUNTIES ARE INCLUDED AS WELL.

OTHERWISE THE REMAINDER OF THE FORECAST APPEARS ON TRACK FOR NOW.

&&

.AVIATION...18Z TAFS...SMOKE FROM AREA WILDFIRES WILL CONTINUE TO
IMPACT THE TAF SITES TODAY THROUGH TOMORROW. MVFR CONDITIONS IN
LOWER VISIBILITIES DUE TO SMOKE AND HAZE WILL BE POSSIBLE...THOUGH
VFR CONDITIONS WILL BE PREVAILING. SURFACE WINDS WILL INCREASE AT
KDLS THIS AFTERNOON WITH GUSTS 20 TO 25 KTS. EXPECT THE WINDS TO
DECREASE LATER TONIGHT. DMH

&&

.PREV DISCUSSION... /ISSUED 600 AM PDT FRI SEP 21 2012/

SHORT TERM...TODAY THROUGH SUNDAY...A HIGH AMPLITUDE HIGH PRESSURE
RIDGE ALOFT WILL PERSIST OVER THE FORECAST AREA FOR ANOTHER DAY WITH
VERY WARM TEMPERATURES...LIGHT WINDS AND MOSTLY CLEAR SKIES. THE
BIGGEST CONCERNS TODAY WILL BE THE THICK SMOKE IN THE ATMOSPHERE DUE
TO THE MANY WILDFIRES IN THE REGION...AND ALSO THE THREAT OF
THUNDERSTORMS THIS WEEKEND. CURRENTLY A FIRE WEATHER WATCH IS IN
EFFECT BEGINNING THIS EVENING TO EARLY SATURDAY MORNING FOR
SOUTHWEST PORTIONS OF THE AREA. THEN THE AREAL COVERAGE OF THE RFW
IS EXPANDED TO COVER MOST OF THE FORECAST AREA DURING THE DAY ON
SATURDAY DUE TO THE EXPECTATION OF MORE WIDESPREAD THUNDERSTORMS ON
SATURDAY. THIS WILL CONTINUE UNTIL LATE SATURDAY NIGHT. THE WATCH
WILL NEED TO BE UPGRADED TO A WARNING ON TODAY'S DAY SHIFT OR
DROPPED...BUT MY FEELING IS THAT IT SHOULD BE UPGRADED TO A RED FLAG
WARNING AS CONFIDENCE IS INCREASING FOR THUNDERSTORMS THIS EVENING
THROUGH LATE SATURDAY EVENING. THE FIRE WEATEHR WATCH IS FOR
THUNDERSTORMS WITH ABUNDANT LIGHTNING AS A PACIFIC LOW PRESSURE
SYSTEM MOVES INTO THE REGION THIS WEEKEND. THE GFS IS MUCH FURTHER
NORTH WITH THE TRACK OF THIS LOW THAN THE ECMWF...AND THIS HAS BEEN
THE CASE FOR THE PAST COUPLE OF DAYS AT LEAST. AS A RESULT
CONFIDENCE OF THE TRACK OF THIS WEATHER SYSTEM IS STILL LOW...AS IS
WHERE THE BULK OF THE PRECIPITATION WILL FALL. IF THE GFS IS CORRECT
THIS COULD MEAN SOME WELL NEEDED RAINFALL FOR THE FORECAST AREA. IF
THE ECMWF TURNS OUT TO BE THE CORRECT MODEL THEN MOST OF THE PRECIP
WILL GO SOUTH OF THE FORECAST AREA INTO SOUTHERN OREGON AND NORTHERN
CALIFORNIA. TEMPERATURES ARE EXPECTED TO COOL OFF AFTER TODAY...
POSSIBLY COOLING OFF TO NORMAL HIGHS. THE SMOKE IN THE FORECAST AREA
HAS THICKENED TO THE POINT OF POOR AIR QUALITY AND UNHEALTHY LEVELS.
AS SUCH AN AIR QUALITY ALERT IS ALSO IN EFFECT FOR THE FORECAST AREA
THROUGH TODAY. EVEN THOUGH THERE IS GOOD VERTICAL MIXING IN THE
AFTERNOON THERE IS A LACK OF HORIZONTAL WINDS TO CARRY THE SMOKE OUT
OF THE REGION AND THEREFORE IT KEEPS BUILDING UP...ESPECIALLY AT
NIGHT WHEN TEMPERATURE INVERSIONS ARE THE STRONGEST. THERE SHOULD BE
IMPROVEMENT WHEN THE PACIFIC NOW PRESSURE SYSTEM MOVES INTO THE
REGION THIS WEEKEND. 88

LONG TERM...SUNDAY NIGHT THROUGH THURSDAY...UPPER LOW WILL STILL BE
OVER THE FORECAST AREA SUNDAY NIGHT. MID LEVEL MOISTURE, DYNAMIC
LIFT, AND WEAK ELEVATED INSTABILITY WILL KEEP A SLIGHT OF SHOWERS
AND THUNDERSTORMS THROUGH SUNDAY EVENING WITH THE CHANCES FOR
CONVECTIVE SHOWERS DECREASING TO NIL BY MIDNIGHT. BY DAYBREAK MONDAY
THE LOW MOVES EAST INTO IDAHO WITH MEAGER WRAP AROUND MOISTURE
KEEPING A SLIGHT CHANCE OF SHOWERS IN THE SOUTHERN BLUE MOUNTAINS
UNTIL NOON AND THEN A SLIGHT CHANCE OF THUNDERSTORMS IN THE SOUTHERN
BLUE MOUNTAINS AND THE WALLOWA MOUNTAINS MONDAY AFTERNOON AND EARLY
EVENING. OTHERWISE, AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL BUILD
INTO CENTRAL AND NORTH CENTRAL OREGON MONDAY AFTERNOON/EVENING AND
THEN MOVE INTO NORTHEAST OREGON AND SOUTHEAST WASHINGTON OVERNIGHT
AND DURING THE DAY ON TUESDAY. THE RIDGE WILL PRODUCE SINKING MOTION
AND THUS DRY CONDITIONS ON TUESDAY. IN THE FORECAST AREA FOR DRY
CONDITIONS IN SOUTHEAST WASHINGTON AND ALSO IN NORTH CENTRAL AND
NORTHEAST OREGON. HOWEVER, THERE WILL BE A SLIGHT CHANCE OF
AFTERNOON AND EARLY EVENING SHOWERS AND THUNDERSTORMS IN CENTRAL AND
EAST CENTRAL OREGON. A VERY WEAK COLD FRONT WILL MOVE THROUGH THE
FORECAST AREA AND USHER IN A MARINE PUSH TUESDAY NIGHT, BUT THIS
WILL BRING JUST SOME MID LEVEL CLOUDS AND NO PRECIPITATION ASIDE
FROM A MOUNTAIN SPRINKLE. OTHERWISE, HIGH PRESSURE WILL DOMINATE THE
REGION WEDNESDAY AND THURSDAY. TEMPERATURES NEXT WEEK WILL BE COOLER
THAN RECENT DAYS, BUT STILL ABOVE NORMAL FOR LATE SEPTEMBER.  POLAN
