AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
830 AM PDT MON AUG 1 2005

.SHORT TERM...UPPER TROUGH IS CURRENTLY MOVING INTO THE PACIFIC
NORTHWEST COAST AT THIS TIME. COOLER MARINE AIR HAS ALREADY BEGUN TO
MOVE INTO THE CASCADES AND OVER THE PASSES AND THROUGH THE COLUMBIA
RIVER GORGE. KDLS AND KELN HAVE INCREASED WINDS ALREADY FROM 15 TO
25 KTS FROM THE NORTHWEST. THIS COOLER MARINE AIR IS PUSHING INTO
THE WARM AND UNSTABLE AIR CURRENTLY OVER THE EASTERN PORTIONS OF THE
FORECAST AREA AND IS CURRENTLY GENERATING THUNDERSTORMS FROM THE
LOWER COLUMBIA BASIN EASTWARD ACROSS THE CWA. THESE STORMS SO FAR
ARE ONLY PRODUCING BRIEF HEAVY RAIN AND FREQUENT LIGHTNING. THIS
AFTERNOON AS SURFACE HEATING REACHES ITS MAXIMUM THESE STORM COULD
PRODUCE MORE SIGNIFICANT RAINFALL AND STRONG GUSTY WINDS...MAINLY
FROM THE BLUE MOUNTAINS EASTWARD AND SOUTHWARD. AT THIS TIME AM NOT
EXPECTING ANY LARGE HAIL OR OTHERWISE SEVERE CRITERIA TO BE
MET...BUT WILL NEED TO MONITOR IT CLOSELY. TEMPERATURES TODAY WILL
BE COOLER BY ABOUT 5 TO 8 DEGREES WITH THE MOST NOTICEABLE COOLING
IN THE WESTERN PORTIONS WHERE THE MARINE AIR IS CURRENTLY MOVING IN.
THE UPPER TROUGH WILL MOVE INLAND TONIGHT AND ACROSS EASTERN OREGON
WASHINGTON LATER ON TUESDAY. THIS WILL KEEP SOME LINGERING
INSTABILITY OVER FAR EASTERN PORTIONS OF THE FORECAST AREA FOR SOME
ISOLATED SHOWERS AND/OR THUNDERSTORMS TUESDAY AFTERNOON AGAIN FROM
THE BLUE MOUNTAINS EASTWARD.  HIGH PRESSURE ALOFT ALOFT WILL THEN
REBUILD FOR THE REMAINDER OF THE WEEK WITH A RETURN TO HOT AND DRY
CONDITIONS.

&&

.PREV LONG TERM DISCUSSION... (ISSUED 250 AM PDT MON AUG 1 2005)

.LONG TERM...THURSDAY THROUGH SUNDAY NIGHT...HIGH PRESSURE WILL
AGAIN DOMINATE THE EXTENDED FORECAST PERIOD.  THE CENTER OF THE HIGH
PRESSURE RIDGE WILL BUILD OVER CENTRAL AND WESTERN NEVADA. MONSOONAL
MOISTURE LOOKS QUITE LIMITED THROUGH THE PERIOD...WITH ONLY
AFTERNOON CUMULUS BUILDING OVER THE EASTERN BLUE/WALLOWA MOUNTAINS.
LATE IN THE EXTENDED...SATURDAY NIGHT THROUGH SUNDAY NIGHT...LONG
TERM MODELS ARE INDICATING SOME MOISTURE MOVING OVER THE AREA FROM
THE SOUTH.  INDICATED AN INCREASE IN AFTERNOON CLOUD COVER OVER THE
EASTERN MOUNTAINS IN RESPONSE TO THIS TREND...BUT HELD OFF ON
MENTIONING SHOWERS DUE TO HIGH LEVELS OF UNCERTAINTY.  CANTIN

.AVIATION...VFR CONDITIONS WILL PREVAIL THE REMAINDER OF TONIGHT
THROUGH THE AFTERNOON.  ISOLATED SHOWERS AND THUNDERSTORMS HAVE BEEN
POPPING UP NEAR TAF SITE KRDM AND ALONG PORTIONS OF TWEB ROUTES 366
AND 368.  THIS ACTIVITY WILL CONTINUE TO MOVE TO THE EAST AND
NORTHEAST.  A LACK OF INSTABILITY TO THE EAST WILL LIMIT THE
POTENTIAL FOR THUNDERSTORMS WITH SHOWERS A POSSIBILITY AT SITES
PSC...ALW...AND PDT.  WINDS IN VICINITY OF THE SHOWERS COULD BE
GUSTY WITH SPEEDS IN EXCESS OF 20KTS POSSIBLE.  96

.FIRE WEATHER...THUNDERSTORMS OVERNIGHT HAVE PRODUCED UP TO A THIRD
OF AN INCH OF PRECIPITATION AT A FEW RAWS SITES AND WITH INCREASED
MOISTURE TODAY...DO NOT EXPECT DRY THUNDERSTORM ACTIVITY. INDEED
SOME THUNDERSTORMS HAVE HAVE HEAVY RAIN OVER LOCALIZED AREAS TODAY.
NONE THE LESS...LIGHTNING CREATED FIRES AND GUSTY OUTFLOW WINDS WILL
BE A STRONG FIRE WEATHER CONCERN TODAY DUE TO THE DRY CONDITIONS OF
MUCH OF THE PAST WEEK. LOCALLY BREEZY WINDS ARE ALSO
POSSIBLE TODAY...ESPECIALLY IN THE EASTERN COLUMBIA GORGE AND THE
COLUMBIA BASIN.  HOWEVER...RHS WILL BE CONSIDERABLY HIGHER THAN THE
PAST FEW DAYS...AND RED FLAG CONDITIONS ARE NOT EXPECTED.
