AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
240 AM PDT SUN SEP 16 2007

.SHORT TERM...TODAY THROUGH MONDAY NIGHT.  A POSITIVE TILT TROUGH
PRESENTLY EXTENDS FROM THE IDAHO PANHANDLE TO NORTHERN
CALIFORNIA...AND DOPPLER RADAR AND SATELLITE SHOWS A FEW SHOWERS
FROM THE BLUE MOUNTAINS EASTWARD.  THERE IS ALSO A THUNDERSTORM OVER
THE HELLS CANYON AREA.  THE REST OF THE AREA IS UNDER MOSTLY CLEAR
SKIES.  ANY CONVECTIVE ACTIVITY SHOULD DIMINISH AROUND SUNRISE THIS
MORNING AS A SHORTWAVE TROUGH MOVING TOWARDS THE COAST FORCES THE
TROUGH OVER OUR FORECAST AREA EASTWARD.  THE STRATUS LAYER WEST OF
THE CASCADES HAS STEEPENED...ALLOWING THE MARINE AIR TO SPREAD
THROUGH THE CASCADE GAPS AND THE COLUMBIA RIVER GORGE.  WINDS ARE
BREEZY IN THE KITTITAS VALLEY AND THE EASTERN COLUMBIA RIVER GORGE
AND WILL CONTINUE TO INCREASE AS THE DAY PROGRESSES.  BY THE
AFTERNOON...VERY WINDY CONDITIONS WILL BE MET AND WILL BE STRONG
ENOUGH IN THE KITTITAS VALLEY TO MEET WIND ADVISORY CRITERIA.  A
WIND ADVISORY WILL BE ISSUED FOR THE KITTITAS VALLEY EFFECTIVE FROM
12 PM TO 8 PM THIS AFTERNOON AND EVENING.  BREEZY WINDS IN THE LOWER
COLUMBIA BASIN WILL RESULT IN PATCHY BLOWING DUST.

THE SHORTWAVE TROUGH APPROACHING THE COAST WILL SPREAD LIGHT SHOWERS
ALONG THE CASCADE CREST DURING THE MID TO LATE AFTERNOON.  THERE
WILL BE ENOUGH LINGERING MOISTURE AND INSTABILITY COMBINED WITH
OROGRAPHIC LIFT IN A WESTERLY FLOW ALOFT TO BRING ISOLATED SHOWERS
AND THUNDERSTORMS OVER THE EASTERN MOUNTAINS THIS AFTERNOON.
PRECIPITATION WILL INCREASE ACROSS EASTERN WA/OR TONIGHT AND EARLY
MONDAY MORNING WITH A 20-40 PERCENT CHANCE OVER THE FORECAST AREA.
THE MARINE PUSH WILL HELP STABILIZE THE AIR MASS...SO WILL NOT
MENTION ANY THUNDERSTORMS TONIGHT OR MONDAY.  THE TROUGH WILL MOVE
INTO IDAHO MONDAY WITH SHOWERS DIMINISHING AND WINDS INCREASING.  IT
WILL BE BREEZY/WINDY AGAIN MONDAY IN THE COLUMBIA BASIN AND
SURROUNDING VALLEYS.  MONDAY NIGHT SHOULD BE DRY OVER MOST OF THE
REGION EXCEPT ALONG THE EAST SLOPES OF THE WA CASCADES AS ANOTHER
UPPER LEVEL TROUGH MOVES ACROSS WESTERN WASHINGTON.  SMITH

.LONG TERM...WEDNESDAY THROUGH SUNDAY...A PACIFIC WEATHER SYSTEM IN
A NORTHWEST FLOW ALOFT WILL MOVE ACROSS THE REGION ON TUESDAY
BRINGING MORE SHOWERS AND COOLER TEMPERATURES. THERE IS FAIRLY
DECENT MODEL TO MODEL CONSISTENCY THROUGH ABOUT 96 HOURS (00Z WED)
SO DO NOT HAVE ANY REAL REASON TO DISAGREE WITH IT. BEYOND 96 HOURS
THE LONGER RANGE MODELS BEGIN TO DIVERGE FROM EACH OTHER MORE WHICH
MAKES THE FORECAST LESS CONFIDENT. IT IS ADVERTISING A RETURN TO A
MORE ZONAL TYPE OF PATTERN WITH SEASONAL TEMPERATURES BY FRIDAY AND
SATURDAY. AFTER THAT THERE ARE SOME VERY SIGNIFICANT CHANGES
DEPICTED BY THE MODELS...ESPECIALLY BY THE GFS...WITH THE ECMWF AND
PREVIOUS GFS RUN NOT AS STRONG WITH THE PRECIP AND/OR COLDER AIR FOR
LATE NEXT WEEKEND. WILL TREND UPWARD WITH THE MOISTURE FOR DAY 7 AND
8 JUST A BIT...BUT NOT MAKE ANY LARGE CHANGES DUE TO THE UNCERTAINTY
THAT FAR OUT IN TIME. 88

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED MOST OF THE TIME DURING THE
NEXT 24 HOURS. MAIN CONCERNS WILL BE INCREASING WINDS TO AT LEAST 10
TO 20 KTS IN THE EASTERN COLUMBIA RIVER GORGE...THE LOWER COLUMBIA
BASIN AND THE BLUE MOUNTAIN FOOTHILLS. TAF SITE KDLS MAY SEE WINDS
AS HIGH AS 20 TO 30 KTS THIS AFTERNOON THROUGH THIS EVENING. THE
INCREASED WINDS MAY CAUSE SOME BLOWING DUST AT KDLS...KPSC...KPDT
AND/OR KALW. AT THIS TIME THE DUST IS NOT EXPECTED TO LOWER THE
VISIBILITY TO BELOW VFR LIMITS. ANY MVFR OR IFR CONDITIONS WILL BE
BRIEF...DUE TO SHOWERS AND LOWERED CEILINGS WITH SHOWERS AND/OR
AFTERNOON THUNDERSTORMS. 88
