.UPDATE...SOME CONVECTION HAS FIRED UP SOUTH OF THE FORECAST AREA
LATE THIS AFTERNOON AND EARLY THIS EVENING. SO FAR ALL THE
CONVECTION HAS STAYED SOUTH OF THE CWA IN HARNEY AND MALHEUR
COUNTIES AND IS ABOUT TO MOVE INTO BAKER COUNTY. THERE WERE SOME
CUMULUS BUILDUPS OVER CENTRAL OREGON OVER DESCHUTES AND CROOK
COUNTIES BUT IT WAS NOT MOIST NOR UNSTABLE ENOUGH TO DEVELOP INTO
THUNDERSTORMS OVER ANYWHERE IN THE CWA. WILL PROBABLY TAKE OUT THE
MENTION OF THUNDERSTORMS FOR THE OVERNIGHT PERIOD AND TUESDAY
MORNING AS IT DOES NOT LOOK LIKE IT WILL MAKE IT THIS FAR NORTHWARD
INTO THE CWA. A WEAK TROUGH PASSAGE WILL TAKE PLACE TONIGHT ACROSS
THE CWA WHICH IS RESPONSIBLE FOR THE CONVECTION THAT HAS DEVELOPED
SOUTH OF THE CWA...AND IT WILL ONLY BRING MID AND HIGH CLOUDS TO THE
CWA. THE WAVE IS EXPECTED TO EXIT THE CWA TUESDAY MORNING. AFTER
THAT HIGH PRESSURE ALOFT WILL AMPLIFY OVER THE INTERMOUNTAIN WEST BY
TUESDAY NIGHT INTO WEDNESDAY WITH VERY WARM TEMPERATURES FOR TUESDAY
AND WEDNESDAY IN A SOUTHERLY FLOW ALOFT. THE FLOW WILL BECOME EVEN
MORE SOUTHERLY BY WEDNESDAY AFTERNOON AS AN UPPER LOW PRESSURE
SYSTEM CURRENTLY OFF THE COAST MOVES TOWARD THE COAST AND EVENTUALLY
MOVES INLAND BY WEDNESDAY NIGHT AND THURSDAY. THE MODELS WEAKEN THIS
SYSTEM AS IT MOVES INTO THE PACIFIC NORTHWEST AND SPLITS IT APART
RESULTING IN JUST A WESTERLY FLOW OVER THE CWA. THIS WILL BRING SOME
SHOWERS TO THE MOUNTAINS WEDNESDAY NIGHT AND THURSDAY...BUT MOISTURE
WILL REMAIN VERY LIMITED AND AM ONLY EXPECTING LIGHT SHOWERS. THERE
WILL BE ENOUGH INSTABILITY OVER THE EASTERN MOUNTAINS ON THURSDAY
FOR POSSIBLE THUNDERSTORMS THURSDAY AFTERNOON AND EVENING...BUT THEY
ARE EXPECTED TO BE WEAK. HIGH PRESSURE ALOFT WILL RETURN TO THE CWA

HIGH BASED PRECIPITATION AND OR THUNDERSTORMS OVER THE EASTERN
MOUNTAINS THROUGH EARLY TUESDAY. ONCE THIS SYSTEM EXITS WE WILL BE
UNDER MOSTLY SUNNY SKIES UNTIL THE NEXT SYSTEM BEGINS INCREASING

WEDNESDAY THEN COOL ON THURSDAY AS THE WESTERLY FLOW BRINGS IN SOME
COOLER AIR.

LONG TERM...THURSDAY NIGHT THROUGH MONDAY...THE PERIOD STARTS OFF
WITH SOME LEFT OVER CLOUDS AND A SLIGHT CHANCE FOR SHOWERS AS AN
UPPER LEVEL DISTURBANCE GRADUALLY MOVES OUT OF THE AREA. EVENTUALLY
THIS SYSTEM BECOMES A CUTOFF LOW NEAR SOUTHERN CALIFORNIA BY
SATURDAY MORNING. BEHIND THIS WE CAN EXPECT RISING HEIGHTS AS THE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
209 PM PDT MON SEP 15 2014

.SHORT TERM...TONIGHT THROUGH THURSDAY...HIGH PRESSURE WILL CONTINUE
OVER THE REGION OVERNIGHT AND TUESDAY WITH A LONG WAVE TROUGH OVER
THE EASTERN PACIFIC. A SMALL AND WEAK DISTURBANCE MOVING OUT OF THE
TROUGH AND UP THE WEST SIDE OF THE RIDGE WILL PRODUCE SOME CLOUDS
ACROSS THE FORECAST AREA OVERNIGHT AND A VERY SLIGHT CHANCE OF SOME
HIGH BASED PRECIPITATION AND OR THUNDERSTORMS OVER THE EASTERN
MOUNTAINS THROUGH EARLY TUESDAY. ONCE THIS SYSTEM EXITS WE WILL BE
UNDER MOSTLY SUNNY SKIES UNTIL THE NEXT SYSTEM BEGINS INCREASING
CLOUDS TUESDAY NIGHT. THIS WILL OCCUR AS THE LONG WAVE TROUGH
APPROACHES THE COAST AND SENDS ANOTHER SHORTWAVE ACROSS THE INLAND
NORTHWEST LATE WEDNESDAY FOLLOWED BY THE TROUGH PASSAGE ON THURSDAY.
HAVE INCREASED PRECIPITATION CHANCES FOR THE WEDNESDAY NIGHT PERIOD
AND THEN DECREASED THEM ON THURSDAY AS INCREASED WESTERLY FLOW WILL
ALLOW THE CASCADE DOWNSLOPE TO CUT OFF PRECIPITATION EXCEPT OVER THE
MOUNTAINS. TEMPERATURES WILL CONTINUE TO RUN ABOVE NORMAL THROUGH
WEDNESDAY THEN COOL ON THURSDAY AS THE WESTERLY FLOW BRINGS IN SOME
COOLER AIR.

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY...THE PERIOD STARTS OFF
WITH SOME LEFT OVER CLOUDS AND A SLIGHT CHANCE FOR SHOWERS AS AN
UPPER LEVEL DISTURBANCE GRADUALLY MOVES OUT OF THE AREA. EVENTUALLY
THIS SYSTEM BECOMES A CUTOFF LOW NEAR SOUTHERN CALIFORNIA BY
SATURDAY MORNING. BEHIND THIS WE CAN EXPECT RISING HEIGHTS AS THE
UPPER LEVEL RIDGE BUILDS OVER THE AREA...THIS WILL LEAD TO DRY AND
WARM WEATHER FOR MUCH OF THE UPCOMING WEEKEND WITH TEMPERATURES AT
LEAST 5-10 DEGREES ABOVE AVERAGE. PREVIOUSLY MENTIONED UPPER LEVEL
CUTOFF LOW MEANDERS OR POSSIBLY EVEN RETROGRADES OFF THE CALIFORNIA
COAST INTO MONDAY WITH THE LATEST ECMWF MODEL RUN COMING INTO BETTER
AGREEMENT WITH THE GFS ON THIS SOLUTION. NEXT SYSTEM LIKELY WON`T
APPROACH THE REGION UNTIL AFTER THE EXTENDED PERIOD...PERHAPS THE
MIDDLE OF NEXT WEEK.


&&

.AVIATION...18Z TAFS...VFR CONDITIONS FORECAST TO PERSIST ACROSS ALL
TAF SITES THROUGH THE PERIOD. A SHORTWAVE DISTURBANCE LOCATED OFF
THE SOUTHERN OREGON COAST WILL GRADUALLY MOVE NORTHWARD INTO THE
AREA BY LATER TODAY BRINGING INCREASING HIGH AND MID LEVEL CLOUDS TO
THE TAF SITES. OVERALL THIS SYSTEM WILL REMAIN WEAK AND MOISTURE
STARVED. PROBABILITY FOR SHOWERS OR THUNDERSTORMS WILL BE SLIGHT
CHANCE OR LESS...BUT CANNOT BE COMPLETELY RULED OUT BETWEEN 21Z
TODAY TO 06Z TUESDAY MAINLY AT  OR INVOF KBDN AND KRDM TAF SITES.
WINDS SHOULD FOLLOW THEIR TYPICAL DIURNAL CYCLE FOR THE MOST PART
THROUGH THE PERIOD...HOWEVER IF ANY SHOWERS OR TSMS WERE TO DEVELOP
A BRIEF AND LOCALIZED WIND GUST COULD OCCUR.

SHORT TERM...TODAY THROUGH WEDNESDAY. UPPER RIDGE OVER THE FORECAST

NORTHERN CALIFORNIA COAST NEAR 40/130 WILL MOVE NORTHEAST ALONG THE
OREGON COAST LATER TODAY. SHOULD SEE INCREASING MID AND HIGH LEVEL
CLOUDS THIS AFTERNOON WITH PARTLY TO MOSTLY CLOUDY SKIES TONIGHT.
WEAK INSTABILITY MAY GENERATE ISOLATED THUNDERSTORMS OVER CENTRAL

AIRMASS IS PRETTY DRY AT THE MOMENT AND MAIN CONCERN FOR CONVECTION
WILL BE LACK OF MOISTURE. WILL CONTINUE WITH SLIGHT CHANCE POPS FOR

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
300 AM PDT MON SEP 15 2014

.SHORT TERM...TODAY THROUGH WEDNESDAY. UPPER RIDGE OVER THE FORECAST
AREA THIS MORNING WITH CLEAR SKIES. AN UPPER LOW CURRENTLY OFF THE
NORTHERN CALIFORNIA COAST NEAR 40/130 WILL MOVE NORTHEAST ALONG THE
OREGON COAST LATER TODAY. SHOULD SEE INCREASING MID AND HIGH LEVEL
CLOUDS THIS AFTERNOON WITH PARTLY TO MOSTLY CLOUDY SKIES TONIGHT.
WEAK INSTABILITY MAY GENERATE ISOLATED THUNDERSTORMS OVER CENTRAL
AND NORTHEAST OREGON LATE THIS AFTERNOON INTO THE OVERNIGHT PERIOD.
AIRMASS IS PRETTY DRY AT THE MOMENT AND MAIN CONCERN FOR CONVECTION
WILL BE LACK OF MOISTURE. WILL CONTINUE WITH SLIGHT CHANCE POPS FOR
NOW. AIRMASS CONTINUES TO WARM ALOFT AND SHOULD HAVE HIGHS TODAY A
FEW DEGREES WARMER THAN SUNDAY. MOST LOCATIONS WILL BE IN THE 80S.
BY TUESDAY THE WEAKENING LOW WILL MOVE OFF TO THE NORTH. A WARM
SOUTHWESTERLY FLOW ALOFT WILL BE OVER THE REGION WITH PARTLY CLOUDY
SKIES AND TEMPS IN THE 80S AGAIN. ON WEDNESDAY A LARGER UPPER LOW
WILL BE APPROACHING THE PACIFIC NORTHWEST. EXPECT INCREASING MID AND
HIGH LEVEL CLOUDS HOWEVER APPEARS THAT MOST OF THE PRECIPITATION
WILL STAY WEST OF THE CASCADES THROUGH WEDNESDAY AFTERNOON.  94

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...THE NEW 00Z GFS, ECMWF
AND CANADIAN MODEL RUNS ALL IN AGREEMENT SHOWING THE ANTICIPATED
PACIFIC TROUGH INCREASING AMPLITUDE SOUTHWARD WEDNESDAY AND
WEDNESDAY NIGHT JUST OFFSHORE OF THE CALIFORNIA COAST RESULTING IN
THE SOUTHERN PORTION OF THE TROUGH PINCHING OFF FROM THE NORTHERN
PORTION OF THE TROUGH DUE TO THE SOUTHERN PART OF THE TROUGH DIGGING
SOUTHEASTWARD INTO NORTHERN CALIFORNIA THURSDAY AFTERNOON/EVENING.
AS SUCH THE ELONGATION OF THE TROUGH ON THURSDAY WILL MEAN THAT THE
MAIN DYNAMIC LIFT WILL BE CARRIED INTO NORTHERN CALIFORNIA AND MISS
THE FORECAST AREA ON THURSDAY SO I HAVE SCALED DOWNWARD THE POPS FOR
THURSDAY, BUT HAVE KEPT A SLIGHT CHANCE OF AFTERNOON AND EVENING
THUNDERSTORMS ALONG THE SOUTHERN BORDER OF THE CWA. THE TROUGH THEN
DEVELOPS INTO A CLOSED MID/UPPER LEVEL LOW PRESSURE SYSTEM PRIOR TO
DAYBREAK ON FRIDAY AND MOVES INTO SOUTHERN CALIFORNIA BY FRIDAY
AFTERNOON. FOR SATURDAY AND SUNDAY HIGH PRESSURE BUILDS OVER THE
REGION FOR DRY CONDITIONS.  POLAN

.UPDATE...HIGH PRESSURE CONTINUES TO DOMINATE THE AREA WITH DRY
CONDITIONS FOR TODAY. AFTERNOON TEMPERATURES SHOULD BE A FEW DEGREES
WARMER THAN YESTERDAY AND OTHER THAN MAKING SOME MINOR ADJUSTMENTS
TO TEMPS AND CLOUD COVER THE PRESENT SHORT TERM FORECAST APPEARS ON
TRACK FOR NOW.

.PREV DISC... /ISSUED 300 AM PDT SUN SEP 14 2014/

SHORT TERM...TODAY THROUGH TUESDAY. UPPER LEVEL RIDGE WITH A DRY
WESTERLY FLOW ALOFT WILL REMAIN OVER THE REGION TODAY. SKIES WILL BE
SUNNY AGAIN WITH HIGHS IN THE UPPER 70S TO MID 80S. WATER VAPOR
IMAGERY CURRENTLY SHOWS AN UPPER LEVEL LOW OFF THE CALIFORNIA COAST
NEAR 140W. THIS LOW WILL MOVE TO NEAR THE OREGON COAST LATE MONDAY.
EXPECT INCREASING HIGH LEVEL CLOUDS DURING THE DAY AS THE UPPER FLOW
TURNS SOUTHWEST. INSTABILITY OVER CENTRAL OREGON IN THE AFTERNOON
AND EARLY EVENING ASSOCIATED WITH THE LOW WILL RESULT IN SCATTERED
SHOWERS AND THUNDERSTORMS. THE WEAKENING LOW WILL MOVE NORTHWARD TO
THE WASHINGTON COAST MONDAY NIGHT. EXPECT MOSTLY CLOUDY SKIES OVER
THE FORECAST AREA WITH ISOLATED SHOWERS. AS THIS SYSTEM MOVES INTO
BRITISH COLUMBIA TUESDAY A SOUTHERLY FLOW ALOFT WILL CONTINUE WITH
PARTLY CLOUDY SKIES. THE AIRMASS WILL BE WARMING MON/TUE WITH HIGHS
IN THE 80S.  94

LONG TERM...TUESDAY NIGHT THROUGH SATURDAY...THE AXIS OF THE
MID/UPPER LEVEL RIDGE OF HIGH PRESSURE WILL BE ALONG THE ROCKIES
TUESDAY NIGHT WHILE A LARGE AMPLITUDE, NEGATIVELY TILTED LONGWAVE
TROUGH WILL BE MOVING EAST NEAR 135W. THIS PATTERN WILL PUT THE
FORECAST AREA IN A SOUTHWEST FLOW ALOFT TUESDAY NIGHT, WHICH WILL
BEGIN TRANSPORTING SOME CLOUDS INTO CENTRAL OREGON OVERNIGHT ON
WEDNESDAY. THE TROUGH WILL BE NEAR 130W BY WEDNESDAY AFTERNOON AND
INTRODUCE DYNAMIC LIFT OVER NORTHEAST OREGON. THIS COMBINED WITH
DAYTIME SURFACE HEATING AND INCREASING MID LEVEL MOISTURE ON THE
EASTERN FLANK OF THE TROUGH WILL MAKE FOR A CHANCE OF SHOWER IN THE
BLUE MOUNTAINS AND A SLIGHT CHANCE OF AFTERNOON/EVENING
THUNDERSTORMS IN NORTHEAST AND EAST CENTRAL OREGON. THE TROUGH
SWINGS INLAND AND ACROSS THE FORECAST AREA ON THURSDAY, WHICH WILL
BRING INCREASING CHANCES OF SHOWERS AS WELL AS A SLIGHT CHANCE OF
AFTERNOON/EVENING THUNDERSTORMS TO SOUTHEAST WASHINGTON AND
NORTHEAST OREGON ON THURSDAY. FOR FRIDAY THE TROUGH EXITS THE REGION
WITH A MID/UPPER LEVEL RIDGE OF HIGH PRESSURE BUILDING OVER THE
REGION FOR DRY AND STABLE CONDITIONS CONTINUING THROUGH SATURDAY.
