AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PENDLETON OR
314 AM PST MON NOV 19 2012
UPDATED AVIATION DISCUSSION
.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...VERY ACTIVE WEATHER
PATTERN THROUGH THE SHORT TERM. PRIMARY CONCERN IS FOR THE HIGH WIND
EVENT THROUGH THIS EVENING. A VERY TIGHT SURFACE PRESSURE GRADIENT
IS SETTING UP ACROSS OREGON AND EXTREME SOUTHEAST WASHINGTON ALONG
WITH VERY STRONG LOW TO MID LEVEL JETS. ALTHOUGH THE PATTERN IS WARM
ADVECTION RATHER THAN COLD...STILL SHOULD SEE SOME DAMAGING WIND
GUSTS THROUGH THIS EVENING. HAVE UPGRADED THE REMAINING FOOTHILL
ZONES TO WARNINGS. DONT NECESSARILY THINK PENDLETON WILL SEE
DAMAGING WINDS BUT PLACES TO THE SOUTH AND EAST MAY...SUCH AS PILOT
ROCK...MISSION...WESTON...AND ATHENA. THE WALLA WALLA AREA WILL
LIKELY SEE STRONGER WINDS THAN PENDLETON. THE WINDS WILL PEAK IN THE
21Z-00Z TIME FRAME THEN SLOWLY DIMINISH AFTER 03Z. IT WILL STILL BE
ON THE BREEZY SIDE OVER THE HIGHER ELEVATIONS RIGHT THROUGH TUESDAY
EVENING. HAVE TRENDED POPS DOWN A BIT IN THE LOWER ELEVATIONS
THROUGH TONIGHT IN LINE WITH LATEST MODEL GUIDANCE AND MOVED
TEMPERATURES UP A BIT. SNOW SHOULD NOT BE MUCH OF AN ISSUE WITH
INCREASING SNOW LEVELS BUT RAIN COULD BECOME A PROBLEM ESPECIALLY
ALONG THE WASHINGTON CASCADE CREST. RAINFALL AMOUNTS OF 2-3 INCHES
WILL BE POSSIBLE BY TUESDAY EVENING. 78
.LONG TERM...WEDNESDAY THROUGH SUNDAY...WEDNESDAY AN UPPER LEVEL
TROUGH AND COLD FRONT WILL MOVE ACROSS EASTERN WASHINGTON AND OREGON
BRINGING ANOTHER ROUND OF RAIN AND BREEZY TO WINDY CONDITIONS. SNOW
LEVELS WILL BE 4000-5000 FEET AHEAD OF THE FRONT DROPPING TO
2000-3500 THURSDAY MORNING. SHOWERS MAY LINGER IN THE MOUNTAINS
WEDNESDAY NIGHT.
A TRANSITORY RIDGE WILL BUILD OFFSHORE WEDNESDAY NIGHT AND MOVE OVER
THE CWA THURSDAY MORNING. THIS WILL BRING MAINLY DRY CONDITIONS TO
EASTERN WASHINGTON AND OREGON EXCEPT NEAR THE CASCADES. A WARM FRONT
WILL MOVE INTO WESTERN WASHINGTON THURSDAY AFTERNOON WITH SNOW
CHANGING TO RAIN ALONG THE CASCADES AND SPILLING INTO THE UPPER
YAKIMA AND KITTITAS VALLEYS THURSDAY EVENING. SNOW LEVELS WILL RISE
OVER 6000 FEET BY FRIDAY EVENING WITH THE RIDGE AND WARM FRONT.
FRIDAY NIGHT A COLD FRONT WILL SAG ACROSS EASTERN WASHINGTON AND
NORTHEASTERN OREGON. THE FRONT WILL HANG UP ALONG THE BLUE MOUNTAINS
SATURDAY AND SATURDAY NIGHT. SATURDAY NIGHT AND SUNDAY THE COLDER
AIR BEHIND THIS SYSTEM WILL FILTER INTO WASHINGTON AND NORTHEASTERN
OREGON. SNOW LEVELS MAY VARY FROM 2000 FEET IN CENTRAL WASHINGTON TO
5500-6000 FEET IN THE OCHOCO MOUNTAINS. SNOW MAY AFFECT THE HOLIDAY
TRAVEL IN THE CASCADES...PARTICULARLY IN WASHINGTON.
SUNDAY MODELS DEVELOP AN OFFSHORE RIDGE BUT DIFFER WITH SOLUTIONS IN
EASTERN WASHINGTON AND OREGON. THE ECMWF DEVELOPS A TROUGH OVER
EASTERN WASHINGTON AND OREGON WHILE THE GFS MOVES THE TROUGH FARTHER
EAST WITH DRY NORTHERLY FLOW OVER THE CWA. DUE TO UNCERTAINTY I DID
KEPT CHANCE PRECIPITATION IN THE MOUNTAINS AND SLIGHT CHANCE IN THE
LOWER COLUMBIA BASIN. COONFIELD
&&
.AVIATION...12Z TAFS...A WEATHER SYSTEM WILL BRING RAIN AND STRONG
SOUTHERLY WINDS TO THE AREA TODAY. THE SOUTHERLY WINDS MAY INHIBIT
SHOWERS AT KRDM, KBDN, KPDT AND KALW DUE TO DOWNSLOPING. WINDS WILL
BE THE MAIN AVIATION CONCERN OVER THE NEXT 24 HOURS. WINDS WILL
INCREASE OVER EASTERN OREGON AND WASHINGTON THIS MORNING. EXPECT
PEAK SUSTAINED WINDS ON MONDAY TO BE BETWEEN 25 TO 40 KNOTS AT
KPDT...KALW...KRDM AND KBDN WITH GUST POTENTIALS TO AROUND 55 KNOTS.
KYKM AND KPSC WILL SEE LESSER WINDS BUT STILL BE VERY WINDY. KDLS
WILL BE PARTIALLY SHELTERED DUE TO THE SOUTHERLY NATURE OF THE
WINDS. 76
