AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
250 PM PST TUE JAN 24 2006

UPDATED AVIATION DISCUSSION

.SHORT TERM...TONIGHT THROUGH FRIDAY.  HIGH PRESSURE AT THE SURFACE
AND ALOFT WILL KEEP DRY CONDITIONS OVER THE FORECAST AREA TONIGHT
THROUGH WEDNESDAY MORNING.  THE RIDGE HAS SHIFTED EASTWARD WITH THE
FLOW BACKING TO THE SW.  THIS IS IN RESPONSE TO AN ELONGATED TROUGH
ALONG 140W. THE TROUGH WILL CONTINUE TO FORCE THE RIDGE EASTWARD
WITH PRECIPITATION SPREADING OVER WESTERN WA/OR WED MORNING THEN
EAST OF THE CASCADES LATE WEDNESDAY AND WEDNESDAY NIGHT.  THE FRONT
IS RATHER WEAK AND WILL BE STRETCHED OUT AS IT MOVES OVER THE
FORECAST AREA...THUS PRECIPITATION CHANCES ARE ONLY 20-40 PERCENT
WEDNESDAY NIGHT AND THURSDAY.  THIS FRONT WILL LEAD THE WAY TO MORE
PROGRESSIVE SYSTEMS.  A STRONGER AND SLIGHTLY MORE ORGANIZED FRONT
WILL QUICKLY FOLLOW ON THURSDAY NIGHT AND FRIDAY.  ALTHOUGH THE
FRONT ON THURSDAY NIGHT DOES NOT APPEAR TO BE A MAJOR HEAVY SNOW
PRODUCER...BELIEVE AN ADVISORY OR POSSIBLE WARNING MAY NEED TO BE
CONSIDERED FOR THE EASTERN MOUNTAINS.  IT IS TOO EARLY TO SAY AT
THIS POINT BUT WILL NEED TO BE DISCUSSED IN THE UPCOMING SHIFTS.

A FREEZING FOG ADVISORY WILL BE ISSUED FOR THE KITTITAS VALLEY
TONIGHT.  THE ELLENSBURG AIRPORT HAS BEEN 1/4 MILE OR LESS MOST OF
THE DAY.  HOWEVER...WEB CAMS ALONG THE HIGHER RIDGES INDICATE THE
FOG AS SHALLOW AND MAINLY OVER THE CITY.  THE INVERSION WILL DEEPEN
SOME TONIGHT...AND FOG WILL LIFT TO COVER MOST OF THE KITTITAS
VALLEY.  THE WALLA WALLA AIRPORT HAS DROPPED TO LESS THAN 1/4 MILE.
FROM WEBCAMS OVER THE CITY...BELIEVE THE DENSE FOG IS PATCHY SO DO
NOT FEEL AN ADVISORY IS NEEDED FOR THE WALLA WALLA VALLEY.

A HIGH WIND WARNING WAS ISSUED FOR THE GRANDE RONDE VALLEY EARLIER
TODAY AND IS IN EFFECT THROUGH 10 PM TONIGHT. WINDS AT THE BASE OF
LADD CANYON WERE SUSTAINED AT 40 KNOTS BUT HAVE DECREASED SOME OVER
THE PAST HOUR.  SURFACE GRADIENTS WILL REMAIN STRONG THROUGH THE
EVENING HOURS WITH THE POTENTIAL FOR DAMAGING WINDS.  SMITH

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY. A DEPARTING LOW PRESSURE
SYSTEM WILL KEEP SOME SHOWERS ACROSS THE AREA FRIDAY NIGHT BEFORE A
STRONGER STORM SYSTEM TAKES AIM ON THE PACNW SATURDAY. MOISTURE WILL
BE ON THE INCREASE AND PRECIPITATION IS EXPECTED TO DEVELOP ACROSS
THE TWO STATE AREA INTO SATURDAY NIGHT. SNOW LEVELS ARE EXPECTED TO
INCREASE ACROSS THE AREA AS WILL SURFACE WINDS PRIMARILY IN AND NEAR
LGD. A BRIEF BREAK IN BETWEEN SYSTEMS IS LIKELY EARLY SUNDAY UNTIL
ANOTHER STORM SYSTEM AFFECTS WA/OR SUNDAY NIGHT AND MONDAY. THIS
STORM LIFTS NORTH BUT SHOWERS SHOULD PERSIST OVER THE WASHINGTON
AREA INTO TUESDAY.

&&

.AVIATION...VFR CONDITIONS WILL CONTINUE FOR ALL TAF LOCATIONS AND
ALONG ALL TWEB ROUTES...EXCEPT FOR KALW WHICH WILL EXPERIENCE SOME
LIFR AND IFR CONDITIONS INTO THE EVENING.  FOG IS THEN EXPECTED TO
