AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PENDLETON OR
1059 AM PDT WED JUL 8 2015

UPDATED AVIATION DISCUSSION

.SHORT TERM...MORNING UPDATE...AN UPPER LEVEL WAVE WILL CONTINUE TO
MOVE SOUTH THROUGH THE PACIFIC NORTHWEST TODAY. THIS WAVE WILL
LARGELY WASH OUT THIS EVENING WITH PART OF IT'S ENERGY BEING PULLED
INTO THE UPPER LOW CURRENTLY OFF THE CALIFORNIA COAST. AS SUCH THE
REGION WILL BE UNDER A RELATIVELY DRIER NORTH TO NORTHEAST FLOW WITH
THE DEEP MOISTURE SUPPRESSED ACROSS SOUTHERN OREGON. FOR THE MOST
PART WILL SEE DRY CONDITIONS WITH ABOVE SEASONAL HIGH TEMPS TODAY. A
FEW SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER THE
RIDGES AND HIGHER TERRAIN OF CENTRAL AND EAST-CENTRAL OREGON, THE
WALLOWA MOUNTAINS AND THE WASHINGTON CASCADE EAST SLOPES. MUCH OF
THIS ACTIVITY SHOULD END AFTER SUNSET THIS EVENING. A FEW SHOWERS OR
STORMS MAY PERSIST OVERNIGHT ALONG SOUTHERN PORTIONS OF DESCHUTES,
CROOK, AND GRANT COUNTIES DUE TO THE APPROACH OF THE DEEP MOISTURE
BAND. UPDATES THIS MORNING COVERED ADJUSTMENTS TO LOCATIONS AND
COVERAGE OF SHOWERS AND THUNDERSTORMS. ALSO MADE SOME MINOR
ADJUSTMENTS TO SKY COVER AND WINDS. 90

.LONG TERM...PREVIOUS DISCUSSION...A SERIES OF UPPER LEVEL
DISTURBANCES WILL MOVE THROUGH WASHINGTON AND OREGON THIS WEEKEND.
EXPECT PERIODS OF SHOWERS AND THUNDERSTORMS WITH THE HIGHEST CHANCE
TO SEE THUNDER DURING THE AFTERNOON AND EVENING WHEN DIURNAL HEATING
ENHANCES THE INSTABILITY ASSOCIATED WITH THE DISTURBANCES. WINDS
WILL BE BREEZY/WINDY FOR PARTS OF THE AREA ON FRIDAY AND SATURDAY
EVENING WITH WINDS OF 15-25KTS AND HIGH GUSTS POSSIBLE. TEMPERATURES
WILL BE MUCH COOLER DUE TO COOLER TEMPERATURES ALOFT ASSOCIATED WITH
THE UPPER LEVEL TROUGHING. THE TROUGH WILL SHIFT EAST MONDAY OR
TUESDAY...WITH THE GFS ENSEMBLES SHOWING SIGNIFICANT SPREAD. WHEN
THE TROUGH FINALLY MOVES EAST OF THE REGION A MUCH DRIER WESTERLY
FLOW WILL START.

&&

.AVIATION...18Z TAFS...VFR FOR THE NEXT 24 HOURS. CUMULUS DEVELOPING
IN CENTRAL OREGON AND OVER THE MOUNTAINS OF NORTHEAST OREGON THIS
AFTERNOON. ISOLATED SHOWERS AND THUNDERSTORMS MAINLY IN THE
AFTERNOON AND EVENING OVER THE MOUNTAINS OF CENTRAL AND EASTERN
OREGON. ANY THUNDERSTORMS THAT DO DEVELOP 21Z-04Z WILL REMAIN SOUTH
AND EAST OF KRDM AND KBDN. WINDS LESS THAN 12 KT, EXCEPT AT KDLS
WHERE GUSTS TO 20 KT AT TIMES. SUSTAINED WINDS 23Z-02Z AT KRDM AND
KBDN WILL BE AROUND 15 KTS FROM 330-360 DEGREES WITH GUSTS TO 23
KTS.  POLAN
