AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PENDLETON OR
354 AM PDT WED JUL 10 2013

UPDATED AVIATION DISCUSSION

.SHORT TERM...TODAY THROUGH FRIDAY...UPPER LEVEL RIDGE WILL BEGIN TO
PUSH OFF TO THE EAST THIS EVENING AND TONIGHT.  FAIR SKIES AND WARM
TEMPERATURES AGAIN TODAY WITH BREEZY TO WINDY CONDITIONS THIS
AFTERNOON ALONG THE KITTITAS VALLEY AND THE COLUMBIA RIVER GORGE DUE
TO AN APPROACHING TROUGH.  THERE HAVE BEEN SOME CHANGES IN THE SHORT
TERM FORECAST MAINLY FOR THE TONIGHT TO EARLY TOMORROW MORNING
PERIOD.  CURRENT VORT MAX CENTERED 36.88N 129.74W WILL SWING UP THE
CALIFORNIA COAST TODAY AND INTO THE CENTRAL OREGON AREA BY THIS
EVENING.  FORCING WITH THIS DISTURBANCE ALONG WITH ELEVATED
INSTABILITY WILL ALLOW FOR A SLIGHT CHANCE OF NOCTURNAL
THUNDERSTORMS ACROSS CENTRAL AND NORTHEAST OREGON AFTER 8PM TONIGHT
THROUGH DAYBREAK TOMORROW.  THERE IS THE POSSIBILITY FOR CONTINUED
THUNDERSTORMS TOMORROW AFTERNOON AS THE FRONTAL SYSTEM PUSHES ACROSS
THE AREA.  WESTERLY FLOW FROM THE UPPER LEVEL TROUGH WILL PROVIDE
COOLER TEMPERATURES AND BREEZY TO WINDY CONDITIONS ACROSS THE LOWER
ELEVATIONS.  THIS PATTERN WILL CONTINUE THROUGHOUT THE REST OF THE
SHORT TERM...WITH THE THREAT FOR THUNDER EXPECTED TO END BY THURSDAY
EVENING.  AS WE APPROACH THE WEEKEND THE FLOW WILL BEGIN TO SHIFT
BACK TO THE SOUTHWEST...BUT TEMPERATURES WILL STILL REMAIN
MILD.  HIGH TEMPERATURES TODAY WILL STILL BE IN THE LOWER TO MID 90S
ACROSS THE LOWER ELEVATIONS...BUT WILL BE IN THE LOWER TO MID 80S
THURSDAY AND FRIDAY DUE TO THE FRONTAL PASSAGE.  MOUNTAINS CAN
EXPECT 70S TO LOWER 80S TODAY WITH 60S THURSDAY AND FRIDAY.  WEBER

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY...UPPER LEVEL PATTERN
REMAINS QUASI-STATIONARY THROUGH THE PERIOD WITH UPPER HIGH
DOMINATING THE CENTRAL US AND A WEAK TROUGH OFF THE WEST COAST.
ALTHOUGH FLOW REMAINS GENERALLY SOUTHWEST...THE ATMOSPHERE REMAINS
TOO DRY FOR CONVECTION.  HOWEVER...THERE COULD BE SOME BUILDUPS OVER
THE MOUNTAINS...ESPECIALLY TUESDAY AFTERNOON/EVENING. THE ECMWF
MODEL SHOWS THE UPPER RIDGE BUILDING BACK OVER THE AREA QUICKER THAN
THE GFS SO WILL HAVE TO WATCH TO SEE IF GFS STARTS TO TREND IN THIS
DIRECTION. TEMPERATURES WILL START OUT NEAR NORMAL BUT QUICKLY WARM
TO ABOVE NORMAL BY MONDAY. EARLE

&&

.AVIATION...12Z TAFS...VFR CONDITIONS WILL CONTINUE FOR ALL TAF
SITES THROUGH THE NEXT 24 HOURS.  SKIES WILL BE CLEAR EXCEPT SOME
AFTERNOON CUMULUS OVER THE MOUNTAINS. WINDS WILL BE GENERALLY 12 KTS
OR LESS...EXCEPT KDLS AND KPDT WHERE WINDS WILL BE 15-20 KTS DURING
THE AFTERNOON AND EVENING.  EARLE

&&

.FIRE WEATHER...TODAY AND TOMORROW...AN UPPER LEVEL TROUGH WILL
BEGIN TO INVADE THE AREA THIS AFTERNOON AND EVENING.  WINDS WILL
BEGIN TO INCREASE ALONG THE COLUMBIA RIVER GORGE...THE YAKIMA VALLEY
AREA...AND THE LOWER COLUMBIA BASIN.  RIGHT NOW WIND RH THREAT
FORECAST IS NEAR RED FLAG IN SOME AREAS...AND SPOTTY RED FLAG IN
OTHER AREAS ACROSS OR/WA FIRE WEATHER ZONES 609...675...AND 631.
CONFIDENCE IS NOT HIGH IN A WARNING DUE TO THE LACK OF
COVERAGE...BUT WOULD NOT BE SURPRISED IF SOME AREAS MEET THE
CRITERIA FOR A COUPLE OF HOURS TODAY.  WINDS WILL STILL BE BREEZY
TOMORROW BUT DONT LOOK AS IMPRESSIVE...THEREFORE CONFIDENCE IS NOT
AS HIGH THAT CONDITIONS WILL BE MET TOMORROW.  AS FAR AS OVERNIGHT
TONIGHT THERE MAY BE SOME NOCTURNAL THUNDERSTORMS IN OR ZONE 610
AND 630 BUT CONFIDENCE IN WHERE THE THUNDER WILL DEVELOP AND IF
ABUNDANT LIGHTNING WILL RESULT IS NOT HIGH ENOUGH FOR A WATCH.
