AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
330 AM PST MON JAN 4 2010

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...A FRONTAL SYSTEM MOVING
INTO THE PACIFIC NORTHWEST WILL BRING PRECIPITATION TO MUCH OF THE
AREA TODAY. THIS SHOULD ALSO HELP TO SCOUR OUT THE PATCHY FOG THAT
HAS DEVELOPED OVER THE LOWER COLUMBIA BASIN. YET OF PRIMARY CONCERN
IS PRECIPITATION TYPE. AS THE MID-LEVEL RIDGE TRIES TO BUILD IN
UNDER THE FRONTAL SYSTEM...WARMER AIR WILL OVERRIDE THE COLD AIR AT
THE SURFACE AND LIGHT FREEZING RAIN MAY BE POSSIBLE IN PORTIONS OF
CENTRAL AND NORTH CENTRAL OREGON AND ALONG THE FOOTHILLS OF THE
OREGON BLUES WHERE TEMPERATURES REMAIN BELOW FREEZING THIS MORNING.
BUT IN AND AROUND THE YAKIMA AND KITTITAS VALLEYS...WHERE FREEZING
RAIN IS USUALLY A CONCERN...THE AIR ALOFT SHOULD STAY COLD ENOUGH
FOR ALL SNOW. SNOW LEVELS WILL THEN RISE HIGH ENOUGH BY THIS
AFTERNOON TO ALLOW SNOW TO CHANGE OVER TO RAIN AT ALL BUT THE
HIGHEST ELEVATIONS. HOWEVER...AS TEMPERATURES DROP OVERNIGHT...LIGHT
FREEZING RAIN COULD BECOME POSSIBLE ALONG THE EAST SLOPES OF THE
CENTRAL WASHINGTON CASCADES AS WELL AS IN THE YAKIMA AND KITTITAS
VALLEYS AND WESTERN PORTIONS OF THE LOWER COLUMBIA BASIN OF
WASHINGTON. NORTHWESTERLY ONSHORE FLOW WILL DEVELOP IN THE WAKE OF
THE FRONTAL SYSTEM AND WILL CONTINUE TO BRING MOISTURE INTO THE
REGION ON TUESDAY AND TUESDAY NIGHT FOR PERIODS OF RAIN AND SNOW
THROUGH WEDNESDAY MORNING.  82

.LONG TERM...WEDNESDAY THROUGH SUNDAY. MODELS AGREE ON THE LARGER
SCALE FEATURES FOR THE EXTENDED WITH AN UPPER RIDGE OVER THE REGION
MID TO END OF THE WEEK THEN AN UPPER TROUGH MOVING THROUGH OVER THE
WEEKEND. A DEPARTING WEATHER SYSTEM WILL KEEP SOME CLOUDS AND
SHOWERS GOING THROUGH WEDNESDAY AFTERNOON. THE UPPER RIDGE WILL
BUILD IN WEDNESDAY NIGHT AND REMAIN OVER THE REGION INTO EARLY
FRIDAY. THIS WILL BRING A PERIOD OF DRY WEATHER WITH PARTLY CLOUDY
SKIES. THERE COULD BE SOME LOW CLOUDS AND FOG IN THE COLUMBIA BASIN
AND VALLEYS IF THE LOW LEVEL INVERSIONS GET STRONG ENOUGH. AN UPPER
TROUGH MOVES THROUGH LATER FRIDAY INTO SATURDAY WITH A CHANCE OF
RAIN AND SNOW. HIGH TEMPERATURES THROUGH THE PERIOD WILL BE IN THE
30S TO LOWER 40S.

&&

.AVIATION...12Z TAFS. IFR/LIFR CONDITIONS WILL CONTINUE AT PDT ALW
DLS THIS MORNING DUE TO FOG AND LOW CLOUDS. A WEATHER SYSTEM WILL
MOVE ACROSS THE REGION TODAY AND TONIGHT BRINGING RAIN TO ALL TAF
SITES. YKM DLS COULD SEE SOME SNOW AS WELL. MVFR CONDITIONS ARE
LIKELY DURING THIS PERIOD OF RAIN. SURFACE WINDS WILL BE LESS THAN
10 KT.
