AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
845 AM PDT WED AUG 6 2014

.SHORT TERM...MINOR UPDATES WILL BE MADE TO THE FORECAST FOR TODAY
AND TONIGHT TO INCREASE TEMPERATURES SEVERAL DEGREES IN A FEW
ZONES. ALTHOUGH COOLER AIR IS SPREADING EAST OF THE CASCADES AND IT
WILL BE SLIGHTLY COOLER TODAY COMPARED TO YESTERDAY...BELIEVE THE
CURRENT FORECAST WAS A BIT TOO LOW TODAY AND TONIGHT.  TODAY'S HIGHS
WILL BE IN THE MID 80S TO MID 90S...AND OVERNIGHT LOWS WILL BE IN
THE 40S MOUNTAINS AND 50S TO LOWER 60S ELSEWHERE.  NO PRECIPITATION
IS FORECAST BUT WINDS WILL BE OUR MAIN CONCERN TODAY.  SEE THE FIRE
WEATHER DISCUSSION ON RED FLAG WARNINGS ISSUED FOR WINDS AND RH'S.
THE MARINE AIR WEST OF THE CASCADES HAS DEEPENED AND IS BANKED ALONG
THE CASCADE WEST SLOPES.  THE 12Z SOUNDING AT QUILLAYUTE INDICATES A
MARINE LAYER AS DEEP AS 5000 FEET.  CONFIDENCE IS HIGH THAT COOLER
AIR WILL BE DEEP ENOUGH TO SPREAD THROUGH THE WASHINGTON CASCADE
GAPS AND SPREAD ACROSS THE COLUMBIA BASIN. WINDS WILL INCREASE AS
THE DAY PROGRESSES AND WILL BECOME BREEZY TO WINDY IN SOME AREAS.

.AVIATION...18Z TAFS...VFR CONDITIONS WITH JUST A FEW HIGH CLOUDS
ARE EXPECTED THROUGH THE FORECAST PERIOD. WINDS WILL PICK UP FROM
THE WEST THIS AFTERNOON AT 10-25 KT AND SUBSIDE OVERNIGHT. THE
STRONGEST WINDS WILL BE AT KDLS AND KPDT. 78

&&

.FIRE WX...RED FLAG WARNINGS ARE CURRENTLY IN EFFECT FOR THE LOWER
COLUMBIA BASIN, WASHINGTON FIRE ZONES 641 AND 675 AND OREGON FIRE
ZONE 641. A WESTERLY FLOW ALOFT WILL CAUSE A MARINE PUSH TODAY.
WINDS WILL REMAIN BREEZY TO WINDY THROUGH THE CASCADE GAPS WITH
WINDS IN THE 10-20 MPH RANGE REACHING INTO THE LOWER COLUMBIA BASIN
THIS AFTERNOON AND EVENING. AFTERNOON RH'S WILL GENERALLY RUN 14 TO
20 PERCENT IN THE BASIN, WHILE IN THE GORGE THEY WILL MAINLY BE IN
THE 20-30 PERCENT RANGE.

&&

.PREV DISC... /ISSUED 426 AM PDT WED AUG 6 2014/

SHORT TERM...TODAY THROUGH THURSDAY NIGHT...WEST TO NORTHWEST FLOW
ALOFT WILL INCREASE ACROSS THE REGION TODAY. THIS FLOW WILL SUPPRESS
ANY LINGERING SUBTROPICAL MOISTURE FURTHER TO OUR SOUTH AND
SOUTHEAST. THUS WILL SEE A DRY DAY WITH MAINLY SUNNY CONDITIONS AND
ONLY A FEW STRAY AFTERNOON CUMULUS CLOUDS OVER THE MOUNTAINS. MARINE
AIR, AS INDICATED BY STRATUS CLOUDS, HAS BEEN INCREASING WEST OF THE
CASCADES EARLY THIS MORNING. THUS THE ANTICIPATED MARINE PUSH TODAY
WILL NOT ONLY LEAD TO INCREASED WINDS INTO THE BASIN (WINDS CONTINUE
BREEZY THROUGH THE CASCADE GAPS), BUT SHOULD BRING SOME LOWERING OF
AFTERNOON HIGH TEMPS. THE WESTERLY FLOW PATTERN WILL CONTINUE
THROUGH THURSDAY NIGHT. AS SUCH CONDITIONS WILL REMAIN FAIR AND DRY
THURSDAY AND THURSDAY NIGHT. WINDS WILL BE LOCALLY BREEZY THURSDAY
AFTERNOON AND EVENING, BUT A BIT LIGHTER THAN TODAY. LOW TEMPS
TONIGHT AND THURSDAY NIGHT, AND HIGHS THURSDAY, WILL RUN NEAR
SEASONAL. 90

LONG TERM...FRIDAY THROUGH TUESDAY...MODELS BRING A TROUGH TO THE
PACIFIC NORTHWEST COAST FRIDAY MORNING. THE ECMWF IS FASTER AND
WEAKER WITH THE TROUGH AND MOVES IT OUT OF THE AREA TO THE EAST BY
SATURDAY MORNING WITH A WEAK RIDGE DEVELOPING SATURDAY NIGHT AND
SUNDAY. THE GFS DEVELOPS A CLOSED LOW IN THE BASE OF THE TROUGH
FRIDAY NIGHT AND THEN PARKS THE TROUGH ALONG THE SOUTHERN OREGON
COAST THROUGH SUNDAY. WITH A SOUTHWEST FLOW ON FRIDAY AND SOME
MOISTURE BEING DRAWN INTO THE AREA FROM THE SOUTH, HAVE A SLIGHT
CHANCE OF THUNDERSTORMS FROM CENTRAL OREGON THROUGH THE HIGHER
TERRAIN OF THE EASTERN MOUNTAINS INTO WALLOWA COUNTY. ON BOTH
SATURDAY AND SUNDAY THE ECMWF WOULD GIVE US FAIR WEATHER WHILE THE
GFS WOULD HAVE A SLIGHT CHANCE OF THUNDERSTORMS OVER MOST OF CENTRAL
OREGON AND THE EASTERN OREGON MOUNTAINS. BELIEVE THE ECMWF IS THE
MORE LIKELY SOLUTION AND THE CURRENT FORECAST RESTRICTS A SLIGHT
CHANCE OF THUNDERSTORMS TO THE HIGHER TERRAIN OF THE EASTERN OREGON
MOUNTAINS SO HAVE LEFT IT AS IS UNTIL BETTER AGREEMENT IS REACHED IN
THE MODELS. BY SUNDAY NIGHT THE GFS MOVES THE CLOSED LOW SOUTH TO
THE NORTHERN CALIFORNIA COAST WHILE THE ECMWF KEEPS A RIDGE OVER US
BUT ALSO DEVELOPS A UNDERCUTTING CLOSED LOW SOUTH OF SAN FRANCISCO.
THIS ALLOWS BOTH MODELS TO BRING MOISTURE INTO THE SOUTHERN PART OF
THE AREA AND GIVES CENTRAL OREGON AND THE EASTERN OREGON MOUNTAINS A
SLIGHT CHANCE OF THUNDERSTORMS MONDAY AFTERNOON AND EVENING. ON
TUESDAY BOTH MODELS BRING A TROUGH INTO THE AREA THAT ABSORBS MUCH
OF THE ENERGY FROM THE CLOSED LOWS. ONCE AGAIN, THERE WILL BE A
SLIGHT CHANCE OF THUNDERSTORMS IN CENTRAL OREGON AND THE EASTERN
OREGON MOUNTAINS. TEMPERATURES WILL START OUT IN THE 80S AND LOWER
90S ON FRIDAY AND WARM A DEGREE OR TWO EACH DAY, ENDING UP IN THE
90S WITH MID TO UPPER 80S IN THE MOUNTAINS BY TUESDAY. PERRY
