AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
213 PM PDT THU MAR 15 2012

.SHORT TERM...TONIGHT THROUGH SUNDAY. A MOIST SW FLOW ALOFT IS
BRINGING RAIN AND HIGH ELEVATION SNOW ACROSS WASHINGTON AND OREGON.
SNOW LEVELS ARE AROUND 6000-7000 FEET.  RAIN WILL BECOME WIDESPREAD
TONIGHT AS A WAVE CURRENTLY OFF THE OREGON COAST TRACKS EASTWARD.
PRECIPITATION AMOUNTS OF 0.25-0.75 OF AN INCH ARE EXPECTED TONIGHT.
DUE TO THE MODERATE RAINFALL AND SNOWMELT RUNOFF...A HYDROLOGIC
STATEMENT WAS ISSUED FOR AREAS IN SOUTHEAST WASHINGTON AND NORTHEAST
OREGON.  ANOTHER WEATHER CONCERN IS THE WINDS AND BLOWING DUST THAT
HAVE BEEN REPORTED ACROSS THE LOWER COLUMBIA BASIN AND THE YAKIMA
VALLEY. THE HANFORD AREA...ESPECIALLY THE WIND-PRONE AREAS...ARE
GETTING GUSTS IN THE 45-50 MPH RANGE.  BLOWING DUST IS CAUSING
TRAFFIC PROBLEMS ALONG HIGHWAY 97 SOUTH OF TOPPENISH.  A WIND
ADVISORY WILL SOON BE ISSUED THAT WILL HIGHLIGHT BOTH WIND AND
BLOWING DUST CONCERNS.

A COLD FRONT WILL MOVE ACROSS THE FORECAST AREA LATE TONIGHT AND
FRIDAY.  A COMPLEX PATTERN SETS UP FRIDAY AND OVER THE WEEKEND AS
THE PARENT TROUGH OFF THE EASTERN PACIFIC MOVES INLAND. THERE ARE
SEVERAL EMBEDDED SURFACE LOWS ASSOCIATED WITH IT.  ONE DEEP LOW WILL
MOVE NORTH ALONG THE COASTLINE FRIDAY NIGHT WHILE A SECONDARY LOW
MOVES ALONG THE BOTTOM OF THE TROUGH AND ACROSS SOUTHERN OREGON.
EASTERN WA/OR REMAIN UNDER A MOIST CYCLONIC FLOW AND SHOULD SEE
PERIODS OF SNOW AND RAIN.  SNOW LEVELS LOWER EACH DAY...AND BY
SUNDAY THE LOWEST ELEVATIONS COULD SEE LIGHT SNOW SHOWERS.  WHILE
PRECIPITATION AMOUNTS SHOULD BE LIGHT THROUGH THE WEEKEND...THE SNOW
ACCUMULATIONS ALONG THE EAST SLOPES OF THE WASHINGTON CASCADES MAY
BE ENOUGH TO WARRANT WINTER HIGHLIGHTS...MORE THAN LIKELY ADVISORIES.

.LONG TERM...SUNDAY NIGHT THROUGH TUESDAY NIGHT...SUNDAY NIGHT AND
MONDAY AN UPPER LEVEL TROUGH WILL BE OVER THE AREA WITH SHOWERY
CONDITIONS EXPECTED MAINLY IN THE MOUNTAINS. WITH COLD AIR OVER THE
AREA, SNOW LEVELS WILL BE AROUND 2000 FEET SO MOST OF THE
PRECIPITATION WILL FALL AS SNOW. LOWS WILL BE IN THE 20S AND LOWER
30S AND HIGHS WILL BE IN THE MID 40S TO MID 50S WITH MID 30S TO
LOWER 40S IN THE MOUNTAINS. MONDAY NIGHT A RIDGE IN THE EASTERN
PACIFIC WILL EXPAND OVER THE PACIFIC NORTHWEST. AFTER A SHORT BREAK
LATE MONDAY NIGHT AND TUESDAY MORNING ANOTHER SYSTEM WILL RIDE OVER
THE RIDGE AND INTO THE AREA WITH A CHANCE OF RAIN AND SNOW ABOVE
3500 TO 4500 FEET. TUESDAY LOOKS LIKE IT WILL HAVE BREEZY SOUTHERLY
WINDS IN THE AFTERNOON AND EVENING. HIGHS WILL BE IN THE UPPER 40S
TO MID 50S WITH 40S IN THE MOUNTAINS. LOWS MONDAY NIGHT AND TUESDAY
NIGHT WILL BE IN THE MID 20S TO MID 30S. PERRY

WEDNESDAY THROUGH THURSDAY NIGHT...MODELS ARE IN FAIR AGREEMENT OF
ANOTHER UPPER LEVEL DISTURBANCE SLOWLY PUSHING ACROSS THE AREA IN
THE EXTENDED. THERE IS INDICATION THAT THE FRONT MAY STALL OUT AS
THE FLOW SHIFT FROM SOUTHWEST TO ALMOST SOUTHERLY.  WEDNESDAY LOOKS
TO BE THE WARMER OF THE TWO DAYS WITH 850 MB TEMPERATURES RUNNING
ABOUT 6 TO 8 DEGREES CELSIUS.  THURSDAY HAS SEVERAL DIFFERENT
POTENTIALS RIGHT NOW.  AS THE FLOW SHIFTS TO THE SOUTH...WARMER AIR
MAY BE TRANSPORTED OVER THE AREA.  BUT IF THE UPPER LEVEL TROUGH OFF
THE COAST PUSHES FURTHER TO THE EAST...THE COLDER AIR WILL LIKELY BE
IN PLACE OVER THE ENTIRE CWA.  ALSO...WHILE THIS SYSTEM IS MOVING
INTO PLACE THERE IS A VERY STRONG UPPER LEVEL RIDGE IN PLACE OVER
THE ENTIRE CONUS...WITH EXCEPTION OF THE PACIFIC NORTHWEST AND THE
NORTHERN CALIFORNIA COASTLINE THAT WILL BE UNDER THE INFLUENCE OF
THE DISTURBANCE.  DUE TO THE STRENGTH AND SIZE OF THE RIDGE IN PLACE
AND THE OVERALL PATTERN IS FOR IT TO POSSIBLY RETROGRADE BACK OVER
THE AREA...AND THE FACT THAT THE FRONTAL SYSTEM MAY STALL OUT OVER
THE AREA AS THE FLOW SHIFT TO THE SOUTH...THURSDAY COULD BE ANYWHERE
FROM COOL AND DAMP TO WARM AND POTENTIALLY DRY. RIGHT NOW POPS ARE
NEAR CLIMO AND A LITTLE HIGHER THAN CLIMO ALONG THE EAST SLOPES OF
THE CASCADES. WEBER

.AVIATION...PREVIOUS DISCUSSION...18Z TAFS...A WEATHER SYSTEM MOVING
ACROSS THE REGION WILL BRING PERIODS OF RAIN TODAY AND THIS EVENING
BEFORE TAPERING OFF OVERNIGHT. CEILINGS WILL GENERALLY BE AT
4000-7000 FT AGL THROUGH THIS EVENING THOUGH MVFR CEILINGS AND
VISIBILITIES WILL BE POSSIBLE WITH THE HEAVIER RAIN BANDS. AFTER 06Z
TONIGHT CEILINGS WILL BEGIN TO LIFT TO 6000-10000 FT AGL. SUSTAINED
WINDS OF 15 TO 25 KTS WITH GUSTS TO 35 KTS WILL BE POSSIBLE AT KRDM
AND KBDN UNTIL 05Z TONIGHT WHEN WINDS WILL DROP BELOW 15 KTS. KDLS
AND KYKM WILL REACH 10 TO 20 KTS THIS AFTERNOON THEN DROP BELOW 15
KTS AFTER 06Z. ALL OTHER TAF SITES WILL REACH 10 TO 20 KTS WITH
GUSTS TO 30 KTS THROUGH 12Z TONIGHT THEN DROP TO 10 TO 15 KTS AFTER
THAT. PERRY
