AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
850 AM PDT TUE AUG 29 2006
.DISCUSSION...BREEZY TO WINDY CONDITIONS WILL CREATE BLOWING DUST
TODAY AND THIS EVENING NEAR PLOWED FIELDS. THERE HAVE ALREADY BEEN
A COUPLE OF REPORTS THIS MORNING OF VISIBILITIES BRIEFLY DOWN TO ONE
QUARTER MILE. AS SUCH A BLOWING DUST ADVISORY HAS BEEN ISSUED FOR
NORTH CENTRAL OREGON...THE LOWER COLUMBIA BASIN OF OREGON...AND THE
FOOTHILLS OF THE BLUE MOUNTAINS OF OREGON AND WASHINGTON THROUGH 8
PM THIS EVENING. A WIND ADVISORY REMAINS IN EFFECT FOR THE KITTITAS
VALLEY. TEMPERATURES STARTED OUT WARM THIS MORNING FOR MANY
LOCATIONS BECAUSE OF WIND AND CLOUD COVER LAST NIGHT. HOWEVER...A
MUCH COOLER AIR MASS IS MOVING INTO THE AREA...THIS MAKES THE
TEMPERATURE FORECAST FOR TODAY TRICKY. AN UPDATE MAY BE NEEDED
LATER THIS MORNING TO LOWER AFTERNOON TEMPERATURES AT SOME
LOCATIONS. ISOLATED THUNDERSTORMS ARE EXPECTED THIS AFTERNOON EAST
OF A COLD FRONTAL BOUNDARY THAT WILL STALL OVER OR JUST EAST OF THE
BLUES. 80
&&
.AVIATION...VIGOROUS UPPER LEVEL TROUGH MOVING OVER PACIFIC
NORTHWEST TODAY. VFR CONDITIONS WILL GENERALLY PREVAIL FOR THE NEXT
24 HOURS. THE EXCEPTION BEING PATCHES OF MVFR/IFR VISIBILITIES
CAUSED BY BLOWING DUST ACROSS THE COLUMBIA BASIN THIS AFTN/EVENING.
IFR VISIBILITIES WERE BRIEFLY REPORTED AT KRDM. HAVE CHOSEN TO LEAVE
OUT LOWER VISIBILITIES OUT OF TAFS...BUT HAVE INSERTED LOCAL 2 MILE
VISIBILITIES INTO TWEB ROUTES 366 AND 368. BREEZY TO WINDY
CONDITIONS WILL PREVAIL ACROSS THE BASIN/GORGE AS WELL...WITH
SUSTAINED WINDS OVER 20 KT AT TIMES...WITH LOCAL GUSTS TO 30-35 KT.

.PREV DISCUSSION... (ISSUED 615 AM PDT TUE AUG 29 2006)
SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...LIGHT SHOWERS
ASSOCIATED WITH THE UPPER WAVE MOVING THROUGH THE PACIFIC NORTHWEST
THIS MORNING SHOULD EXIT NORTHEAST OREGON/SOUTHEAST WASHINGTON BY
AROUND 5 AM. MEANWHILE THE MARINE PUSH CONTINUES TO STRENGTHEN WEST
OF THE CASCADES...WITH SOME OF THE MOISTURE ALREADY SEEPING EAST OF
THE CREST. WINDS SHOULD GRADUALLY INCREASE THROUGH THE DAY WITH THE
STRONGEST WINDS ACROSS THE COLUMBIA BASIN AND THROUGH THE GAPS IN
THE CASCADES. COULD SEE PATCHY BLOWING DUST OVER PORTIONS OF THE
COLUMBIA BASIN BY THIS AFTERNOON. THE MARINE PUSH FRONT WILL MOVE
SLOWLY ACROSS THE BLUE...WALLOWA...OCHOCO AND STRAWBERRY MOUNTAINS
THIS AFTERNOON AND EVENING. THE INTERACTION BETWEEN THIS FRONT AND
ANOTHER UPPER WAVE MAY RESULT IN A FEW SHOWERS OR THUNDERSTORMS
OVER THESE AREAS. INCREASING WEST FLOW ACROSS THE CASCADES WILL CAP
AND ELIMINATE ANY THREAT OF SHOWER/THUNDERSTORMS OVER DESCHUTES AND
JEFFERSON COUNTIES IN CENTRAL OREGON. THE UPPER TROUGH THEN MOVES
ACROSS THE REGION LATER TONIGHT THROUGH WEDNESDAY EVENING. THIS
SYSTEM WILL KEEP A SLIGHT CHANCE OF SHOWERS GOING OVER THE MOUNTAIN
ZONES THROUGH WEDNESDAY EVENING. SHOWERS OVER THE CENTRAL OREGON
MOUNTAINS SHOULD END BY MID DAY WEDNESDAY DUE TO INCREASING
STABILITY AND A DRYING OF THE AIR MASS. THE AIR MASS LOOKS TO BE TOO
STABLE WEDNESDAY TO SUPPORT THUNDERSTORMS...THOUGH ADDED LIFT DUE TO
UPSLOPING OF THE WEST WINDS MAY RESULT IN A STRAY THUNDERSTORM OVER
THE BLUE MOUNTAINS IN WASHINGTON. 90
LONG TERM...THURSDAY THROUGH MONDAY...MEDIUM RANGE MODELS IN
AGREEMENT WITH DRIER NORTHWEST FLOW ALOFT FOR LATE IN THE
WEEK...RIDGING ACROSS THE REGION FOR THE WEEKEND...THEN INCREASING
SOUTHERLY FLOW EARLY NEXT WEEK. DRY WEATHER WILL PREVAIL...WITH
BELOW NORMAL TEMPERATURES THURSDAY...NEAR NORMAL FOR FRIDAY...WITH
SEASONABLY WARM TEMPERATURES FOR SAT THRU MON. WILL HOLD OFF ON ANY
PRECIP MENTION FOR MONDAY...USING HIGHER CLOUD COVER.
FIRE WEATHER...WINDS WILL INCREASE ACROSS THE COLUMBIA BASIN
TODAY...BUT THE MARINE PUSH SHOULD ALLOW THE RHS TO INCREASE AS
WELL. THERE MAY BE A BRIEF PERIOD WHERE WINDS AND RHS APPROACH
HAZARDOUS FIRE CONDITION CRITERIA ALONG THE BLUE MOUNTAIN
FOOTHILLS...BUT AT THIS TIME THE THREAT LOOKS TO BE VERY MARGINAL.
