AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
300 AM PST SUN DEC 18 2005

.SHORT TERM...TODAY THROUGH MONDAY NIGHT. THE TWO WEEKS OF LOW
CLOUDS...FOG...AND VERY STABLE CONDITIONS ARE COMING TO AN END.  THE
STRATUS CLOUDS ARE ERODING ACROSS THE COLUMBIA BASIN.  FOG SATELLITE
SHOW THE COLD AND DRY AIR FROM A BACKDOOR FRONT CLEARING OUT THE
COLUMBIA BASIN FROM THE NORTH.  EARLY MORNING TEMPERATURES IN THE
LOWER COLUMBIA BASIN OF WASHINGTON AND THE BLUE MOUNTAIN FOOTHILLS
ARE PLUMMETING INTO THE SINGLE DIGITS AT THIS HOUR.

A WARM FRONT IS CURRENTLY APPROACHING THE SW OR COAST.  THIS FRONT
WILL TRACK TO THE NE AND WILL SPREAD SNOW ACROSS THE EAST SLOPES OF
THE OREGON CASCADES THIS AFTERNOON WITH SNOW SPREADING AS FAR EAST
AS PRINEVILLE AND CONDON BY LATE AFTERNOON.  SNOW WILL THEN SPREAD
ACROSS THE EASTERN COLUMBIA RIVER GORGE AND THE EAST SLOPES OF THE
SOUTHERN WA CASCADES THIS EVENING.  BY EARLY MONDAY MORNING...THESE
AREAS WILL SEE A MIXTURE OF SNOW...SLEET...AND FREEZING RAIN AS
TEMPERATURES ALOFT WARM TO ABOVE FREEZING.  WITH THIS IN MIND...WILL
ISSUE A WINTER STORM WARNING FOR CENTRAL AND NORTH CENTRAL OREGON
FOR THIS AFTERNOON THROUGH MONDAY AFTERNOON AND A WINTER STORM WATCH
FOR THE JOHN DAY-OCHOCO HIGHLANDS...THE EASTERN COLUMBIA RIVER
GORGE...AND THE EAST SLOPES OF THE SOUTHERN WASHINGTON CASCADES FOR
TONIGHT THROUGH MONDAY AFTERNOON. FOR THE REMAINDER OF THE FORECAST
AREA...THE FRONT WILL BEGIN TO SHEAR APART AS IT MOVES EASTWARD
WITH LIGHT SNOW OVER THE REGION BY MONDAY MORNING.   TEMPERATURES
ALOFT WILL WARM AND SNOW WILL CHANGE TO A MIXTURE OF SNOW AND SLEET
BY MONDAY AFTERNOON.  AT THIS TIME...BELIEVE SNOW ACCUMULATIONS WILL
NOT MEET HEAVY SNOW WARNING CRITERIA AND ANY ICE ACCUMULATIONS WILL
BE LIGHT.  HOWEVER...DAY SHIFT MAY NEED TO ISSUE STATEMENTS IF THE
SYSTEM MAINTAINS ITS STRENGTH AS IT MOVES CLOSER TO THE AREA.

BY MONDAY NIGHT...INCREASING WARM AIR ADVECTION AND MOISTURE WILL
CONTINUE TO SPREAD ACROSS THE REGION.  CENTRAL OREGON AND AREAS IN
THE JOHN DAY-OCHOCO HIGHLANDS WILL WARM ABOVE FREEZING AND WILL SEE
THE WINTERY MIX GRADUALLY CHANGE TO RAIN.  ELSEWHERE...THE WINTERY
MIX WILL CONTINUE.  SMITH

.LONG TERM...TUESDAY THROUGH SATURDAY...AN UPPER RIDGE AXIS WILL BE
LOCATED EAST OF THE FORECAST AREA WITH A DEEP MOIST AND WARMER
SOUTHWEST FLOW ALOFT OVER THE CWA. THIS PATTERN WILL PERSIST THROUGH
FRIDAY WITH EMBEDDED WEATHER DISTURBANCES IN THE FLOW MOVING THROUGH
THE PACIFIC NORTHWEST. EACH OF THESE SYSTEMS WILL BRING A SURGE OF
ADDITIONAL MOISTURE WITH INCREASING TEMPERATURES ALOFT DUE TO WARM
AIR ADVECTION. THIS WILL CAUSE MOST OF THE PRECIP TO CHANGE OVER TO
ALL RAIN BY THE END OF THE WEEK. AT FIRST HOWEVER MOST PLACES WILL
HAVE A WINTRY MIX OF RAIN...FREEZING RAIN AND SNOW ON TUESDAY AND
TUESDAY NIGHT. DUE TO THE VERY COLD AIR AND STRONG SURFACE BASED
INVERSIONS THAT ARE CURRENTLY IN PLACE OVER THE FORECAST AREA AND
NOT MUCH WIND WITH THESE WEATHER SYSTEMS THE COLD AIR IN THE
COLUMBIA BASIN AND ADJACENT VALLEYS WILL BE HARD TO MIX OUT. AS SUCH
THERE COULD BE A LENGTHY PERIOD OF ICING ON TUESDAY AND TUESDAY
NIGHT. EVEN IF TEMPERATURES RISE A LITTLE ABOVE FREEZING RAIN COULD
STILL FREEZE ON THE GROUND SINCE HAS BEEN SO COLD FOR SO LONG AND
THE GROUND IS FROZEN TO A SIGNIFICANT DEPTH. THIS WILL BE ESPECIALLY
TRUE AT NIGHT. AS PREVIOUSLY MENTIONED HOWEVER MOST OF THE
PRECIPITATION WILL BECOME ALL RAIN BY THE END OF THE WEEK INTO THE
WEEKEND WITH MUCH WARMER AIR MOVING IN. THE ONLY PLACES IN QUESTION
ARE THE YAKIMA AND KITTITAS VALLEYS WHICH ARE TYPICALLY THE LAST TO
MIX OUT. 88

&&

.AVIATION...ALL TAF SITES WILL HAVE GOOD VISIBILITY GREATER THAN 6
MILES AND VFR TO MVFR CONDITIONS THROUGH THE NEXT 24 HOURS. MUCH OF
THE LOW CLOUDS AND PATCHY FREEZING FOG HAS DISSIPATED DURING THE
PAST 24 HOURS DUE TO A SURGE OF DRIER AND COLDER AIR FROM THE
NORTHEAST YESTERDAY (SATURDAY). CEILINGS ARE ABOVE 1000 FEET AGL AT
ALL TAF LOCATIONS AND IN SOME AREAS SUCH AS IN THE COLUMBIA BASIN
CEILINGS ARE BROKEN AND/OR ABOVE 2000 FEET AGL. THE AREA OF LOW
CLOUDS AND FOG IS GRADUALLY INCREASING IN COVERAGE AGAIN THIS
MORNING...BUT THAT WILL BE SHORT LIVED TODAY AS A NEW WEATHER SYSTEM
MOVES INTO THE REGION FROM THE SOUTHWEST. 88
