AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE PENDLETON OR
259 AM PDT SUN JUL 12 2009

CORRECTED SHORT TERM DISCUSSION

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...THE UPPER LOW NEAR
43N/128W IS STARTING TO DRIFT TOWARDS THE SOUTHWEST OREGON COAST.
THIS UPPER SYSTEM WILL MOVE ONSHORE TODAY AND MOVE SLOWLY ACROSS THE
REGION TONIGHT. CURRENTLY THERE IS LITTLE MID AND UPPER LEVEL
MOISTURE WITH THIS SYSTEM...JUST ENOUGH FOR A FEW ELEVATED SHOWERS
AND THUNDERSTORMS NEAR THE OREGON COAST THIS MORNING. MEANWHILE
THERE IS A PLUME OF SUBTROPICAL MOISTURE THAT HAS NOW MADE ITS WAY
INTO EASTERN OREGON AND SOUTHEAST WASHINGTON. AS THE UPPER LOW MOVES
ONSHORE TODAY IT WILL BEGIN TO PULL THIS SUBTROPICAL MOISTURE INTO
ITSELF...PROVIDING THE FUEL FOR THE SHOWERS AND THUNDERSTORMS
EXPECTED THIS AFTERNOON AND TONIGHT. A FEW LIGHT SHOWERS...MOSTLY
ALOFT WILL CONTINUE THROUGH THE MORNING UNDER THE SUBTROPICAL
MOISTURE PLUME. MAY ALSO SEE A STRAY THUNDERSTORM DEVELOP LATE THIS
MORNING AS WELL. MEANWHILE...A FEW SHOWERS OR THUNDERSTORMS MAY
DEVELOP THIS MORNING NEAR THE CASCADE CREST AS THE UPPER LOW GETS
CLOSER TO THE COAST. THIS AFTERNOON EXPECT A BROAD BAND OF SHOWERS
AND THUNDERSTORMS TO DEVELOP NEAR THE CASCADES...ALONG AND AHEAD OF
A COLD FRONT THAT IS EXPECTED TO FORM. THE UPPER LOW WILL PUSH THIS
BOUNDARY AND ASSOCIATED SHOWERS AND STORMS ACROSS THE REGION LATE
THIS AFTERNOON AND TONIGHT. SHEAR AND LIFT ALONG THIS BOUNDARY
SHOULD BE SUFFICIENT ENOUGH TO CAUSE STRONG...POSSIBLY SEVERE...
STORMS WITH GUSTY WINDS AND HAIL LATE THIS AFTERNOON AND THIS
EVENING. THE UPPER LOW WILL WEAKEN AND CONTINUE TO MOVE NORTHEAST
INTO WESTERN MONTANA MONDAY. THUS WILL RESULT IN CHANCES OF SHOWERS
AND THUNDERSTORMS TO DIMINISH FROM THE WEST THROUGH THE DAY. DRY AIR
WILL MOVE INTO THE REGION MONDAY NIGHT AND BRING AN END TO ANY
LINGERING SHOWERS.

DUE TO THE EXPECTED LIGHTNING ACTIVITY TODAY AND TONIGHT OVER LOW
ELEVATION AREAS WHERE FINE FUELS HAVE DRIED OUT...A FIRE WEATHER
WATCH HAS BEEN ISSUED. ALSO WINDS WITH THE THUNDERSTORMS AND BEHIND
THE COLD FRONT COULD FAN ANY NEW STARTS. 90

.LONG TERM...TUESDAY THROUGH SUNDAY...THE COMPUTER MODELS REMAIN IN
GOOD AGREEMENT THROUGHOUT THE EXTENDED PERIOD. A RIDGE OF HIGH
PRESSURE WILL BUILD IN FROM THE WEST ON TUESDAY AND THEN STRENGTHEN
AS IS PROGRESSES EASTWARD ON WEDNESDAY AND THURSDAY. THIS PATTERN
WILL FACILITATE A WARMING TREND THAT WILL KEEP DAYTIME HIGHS SEVERAL
DEGREES ABOVE NORMAL THROUGH NEXT WEEKEND. MOSTLY CLEAR SKIES CAN
ALSO BE EXPECTED DURING THIS PERIOD...ALTHOUGH SCATTERED MID AND
HIGH CLOUDS COULD BEGIN MOVING INTO THE AREA ON FRIDAY AS TROUGHING
DEVELOPS IN THE EASTERN PACIFIC. WINDS WILL REMAIN LIGHT. 82

&&

.AVIATION...12Z TAFS...SCATTERED-BROKEN MID AND HIGH LEVEL CLOUDS
WILL REMAIN OVER THE AREA THIS MORNING WITH BASES GENERALLY ABOVE
10000 FT AGL. THIS AFTERNOON WILL BE ACTIVE WITH THUNDERSTORMS IN
THE VICINITY OF TAF SITES AT TIMES. THERE IS A CHANCE THAT SOME
STORMS WILL PRODUCE STRONG WIND GUSTS...LARGE HAIL...AND LOW
VISIBILITIES. WESTERLY SURFACE WINDS WILL INCREASE IN THE LATE
AFTERNOON/EVENING AFTER A COLD FRONT PASSAGE...WITH GUSTS TO 30-35
KTS POSSIBLE. 82
