NATIONAL WEATHER SERVICE PENDLETON OR
1019 PM PDT WED OCT 22 2014

UPDATED AVIATION DISCUSSION

.SHORT TERM...TONIGHT AND THURSDAY...LARGE UPPER LEVEL TROUGH OF LOW
PRESSURE CONTINUES OVER THE GULF OF ALASKA WITH A FRONTAL BOUNDARY
OVER THE PACIFIC NORTHWEST. PRECIPITATION ALONG THIS FRONT HAS BEEN
MOVING THROUGH THE FORECAST AREA BEING PUSHED EASTWARD BY A
SHORTWAVE COMING AROUND THE BOTTOM OF THE TROUGH. CURRENTLY THE
FRONT STRETCHES FROM SPOKANE THROUGH PENDLETON AND DOWN TO MEDFORD.
THIS WILL MOVE THROUGH THE EASTERN PORTION OF THE FORECAST AREA
OVERNIGHT PRODUCING A STEADY LIGHT RAIN. BEHIND IT A MOIST SOUTHWEST
FLOW WITH CONTINUED BANDS OF PRECIPITATION WILL PRODUCE SHOWERS FOR
THE REST OF THE FORECAST AREA OVERNIGHT AND CONTINUE ON THURSDAY FOR
THE ENTIRE FORECAST AREA. WILL ALSO CONTINUE TO SEE SOME BREEZY
SOUTH WINDS OVERNIGHT BUT FOCUSED MORE OVER OREGON AND THE HIGHER
TERRAIN.

.AVIATION...06Z TAFS...OVERCAST SKIES OVERNIGHT WITH OCCASIONAL RAIN
SHOWERS WILL BECOME BROKEN ON THURSDAY BUT REMAIN VFR. WINDS WILL
BE MOSTLY OUT OF A SOUTHERLY DIRECTION AND GUSTY AT TIMES. WINDS
WILL LESSEN SOME OVERNIGHT...THEN BECOME 15 TO 25 MPH AND SHIFT
SOUTHWESTERLY AROUND MIDDAY THURSDAY.

.PREV DISC... /ISSUED 358 PM PDT WED OCT 22 2014/

SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT...AN UPPER TROUGH OVER
THE GULF OF ALASKA AND THE EASTERN PACIFIC WILL KEEP THE FLOW OVER
THE PACIFIC NORTHWEST WEST-SOUTHWESTERLY THROUGH THURSDAY. AN UPPER
LEVEL DISTURBANCE WILL PUSH AN ASSOCIATED COLD FRONT THROUGH THE
REGION TONIGHT. AS SUCH, EXPECT GOOD CHANCES OF PRECIP AREAWIDE
DURING THE TONIGHT PERIOD. WINDS WILL CONTINUE LOCALLY BREEZY OVER
THE MOUNTAINS, THE GRANDE RONDE VALLEY, THE WALLOWA VALLEY AND THE
BLUE MOUNTAIN FOOTHILLS PRIOR TO THE FRONTAL PASSAGE. A BRIEF PERIOD
OF BREEZY WINDS MAY ALSO ACCOMPANY THE FRONTAL PASSAGE. ON THURSDAY,
EXPECT SHOWERS TO PERSIST, ESPECIALLY NEAR THE CASCADE CREST AND
OVER THE NORTHEAST OREGON MOUNTAINS. THERE IS JUST ENOUGH
INSTABILITY INDICATED OVER EXTREME NORTHEAST OREGON THURSDAY
AFTERNOON TO WARRANT INCLUDING A MENTION OF THUNDER. THE SHOWERS
WILL WIND DOWN THURSDAY EVENING AS HIGH PRESSURE ALOFT BUILDS OVER
THE REGION IN RESPONSE TO A SOUTHWARD DIGGING OF THE OFFSHORE UPPER
TROUGH. THE AMOUNT OF EXPECTED DIGGING BY THE TROUGH HAS RESULTED IN
AN EXPECTED SLOW DOWN OF THE ARRIVAL OF THE NEXT PACIFIC SYSTEM. AT
THIS TIME STILL EXPECT THIS NEXT SYSTEM`S WARM FRONT TO MOVE NORTH
ACROSS THE REGION, BUT WITH A SLOWER TIMING. THUS WILL SHOW THE WARM
FRONTAL PRECIP MAINLY AFFECTING OUR OREGON ZONES FRIDAY AND OUR
WASHINGTON ZONES FRIDAY NIGHT. SNOW LEVELS WILL REMAIN ABOVE 5000
FEET THROUGH THIS ENTIRE PERIOD. 90

LONG TERM...SATURDAY THROUGH WEDNESDAY...SATURDAY WILL BEGIN MOSTLY
DRY...EXCEPT ALONG THE CASCADES. HOWEVER...BREEZY SOUTHERLY WINDS
CAN BE EXPECTED OF 15 TO 25 MPH. THEN AS THE UPPER TROF AND COLD
FRONT MOVE ACROSS THE AREA LATE SATURDAY AND SUNDAY...WINDS WILL
SHIFT WESTERLY AND SURGES OF MOISTURE WILL AFFECT MAINLY THE
MOUNTAINS. SNOW LEVELS WILL FALL...BUT WILL REMAIN ABOVE 4500 IN
WASHINGTON AND ABOVE 5000 IN OREGON SO IMPACTS WILL BE MINIMAL.
SLIGHTLY DRIER CONDITIONS RETURN MONDAY...BUT ANOTHER UPPER LEVEL
TROUGH IS EXPECTED TO MOVE ACROSS THE AREA TUESDAY AND WEDNESDAY. IT
IS POSSIBLE THIS TROUGH MAY CONTAIN SOME LEFTOVER MOISTURE AND
ENERGY FROM TROPICAL SYSTEM ANA AS IT GETS ENTRAINED INTO THE
WESTERLY FLOW AND MERGES WITH A MID-LATITUDE SYSTEM. HOWEVER...THE
MODELS DO NOT AGREE WELL ON THE TIMING AND INTENSITY OF THE
DISTURBANCE AS IT CROSSES THE PACIFIC NORTHWEST. AT THIS TIME THERE
IS CONFIDENCE THAT UNSETTLED WEATHER WILL CONTINUE INTO THE MIDDLE
OF NEXT WEEK...BUT IT IS UNCERTAIN HOW MUCH PRECIPITATION WILL FALL
WHEN AND WHERE. COBB

PRECIPITATION HAS DEVELOPED IN THE EASTERN VALLEYS OF THE CASCADES
AND WILL GRADUALLY SPREAD ACROSS THE FORECAST AREA OVERNIGHT.  DUE

TAP FROM THE REMAINS OF TYPHOON VONGFONG. RAIN WILL ALSO BE SLOW TO
SPREAD EASTWARD...AS THE UPPER LEVEL FLOW IS PARALLEL TO THE
FRONT...AND WILL EVENTUALLY DEVELOP OVER ALL AREAS BY WEDNESDAY
NIGHT.  A COLD FRONT WITH THE SYSTEM WILL LOWER SNOW LEVELS DOWN TO
6000-6500 FEET ALONG THE CASCADES THURSDAY.  48-HOUR PRECIPITATION

ALONG WITH A STRONG UPPER LEVEL JET WILL BE POINTED AT THE PAC NW
DURING THIS PERIOD. THIS WILL LEAD TO PLENTY OF CLOUDS AND A GOOD
CHANCE FOR RAIN...OR SNOW ABOVE 5000 TO 7000 FEET THURSDAY NIGHT
INTO EARLY FRIDAY. BY LATE FRIDAY INTO SATURDAY A DEVELOPING UPPER
LEVEL LOW SHOULD TURN THE FLOW MORE SOUTHERLY...PERHAPS LEADING TO A
SHORT BREAK IN THE ACTIVE WEATHER. BY SATURDAY NIGHT INTO SUNDAY THE
UPPER LEVEL DISTURBANCE MOVES OVER THE REGION BRINGING INCREASES
CHANCES FOR SHOWERS AND COOLER TEMPERATURES. SNOW LEVELS SHOULD ALSO
LOWER TO BETWEEN 5000 TO 6000 FEET DURING THIS TIME. FOLLOWING THIS
SYSTEM...WHAT APPEARS TO BE A RATHER WEAK AND TRANSIENT UPPER LEVEL
RIDGE WILL TRY TO BUILD BACK INTO THE AREA ON MONDAY. HIGH
TEMPERATURES ARE FORECAST TO BE RIGHT AROUND AVERAGE FOR THIS TIME

PRECIPITATION HAS DEVELOPED IN THE EASTERN VALLEYS OF THE CASCADES
AND WILL GRADUALLY SPREAD ACROSS THE FORECAST AREA OVERNIGHT.  DUE
TO THE STRONGEST ENERGY TO THE SOUTH...THE SOUTHERN BLUES AND JOHN
DAY-OCHOCO HIGHLANDS WILL LIKELY RECEIVE 0.1"-0.25" OF RAIN
OVERNIGHT.  THE TROUGH WILL SWING TO THE NORTHEAST AS IT MOVES INTO
IDAHO EARLY TUESDAY MORNING...AND SIMILAR PRECIPITATION AMOUNTS ARE
FORECAST OVER THE NORTHERN BLUES AND WALLOWAS.  THERE WILL BE A
BREAK BETWEEN SYSTEMS TUESDAY AND TUESDAY EVENING BEFORE THE NEXT
UPPER LEVEL SYSTEM MOVES ONSHORE TUESDAY NIGHT.  THIS SYSTEM IS
CURRENTLY STRENGTHENING BETWEEN 140-150W OVER THE GULF OF
ALASKA...AND WATER VAPOR LOOPS CLEARLY SHOW A SIGNIFICANT MOISTURE
TAP FROM THE REMAINS OF TYPHOON VONGFONG. RAIN WILL ALSO BE SLOW TO
SPREAD EASTWARD...AS THE UPPER LEVEL FLOW IS PARALLEL TO THE

AND 20/12Z GFS AGREE THAT A PLUME OF DEEP...SUBTROPICAL MOISTURE
ALONG WITH A STRONG UPPER LEVEL JET WILL BE POINTED AT THE PAC NW
DURING THIS PERIOD. THIS WILL LEAD TO PLENTY OF CLOUDS AND A GOOD
CHANCE FOR RAIN...OR SNOW ABOVE 5000 TO 7000 FEET THURSDAY NIGHT
INTO EARLY FRIDAY. BY LATE FRIDAY INTO SATURDAY A DEVELOPING UPPER
LEVEL LOW SHOULD TURN THE FLOW MORE SOUTHERLY...PERHAPS LEADING TO A
SHORT BREAK IN THE ACTIVE WEATHER. BY SATURDAY NIGHT INTO SUNDAY THE
UPPER LEVEL DISTURBANCE MOVES OVER THE REGION BRINGING INCREASES
CHANCES FOR SHOWERS AND COOLER TEMPERATURES. SNOW LEVELS SHOULD ALSO
LOWER TO BETWEEN 5000 TO 6000 FEET DURING THIS TIME. FOLLOWING THIS
