NATIONAL WEATHER SERVICE PENDLETON OR
930 AM PST SAT NOV 16 2002

PRECIPITATION ASSOCIATED WITH THE FRONT IS NOW APPROACHING THE WEST
SIDE OF THE CASCADE CREST. EXPECT THIS PRECIP BAND TO HOLD TOGETHER
AS IT CROSSES THE CREST...PARTICULARLY IN WASHINGTON AND WILL UP
POPS IN THE WASHINGTON CASCADE EAST SLOPE ZONE AND THE KITTITAS
VALLEY ZONE. AIR MASS IN THIS AREA LOOKS TO BE COOL ENOUGH FOR LIGHT
SNOW FROM THE PRECIP BAND...THOUGH THERE IS A CHANCE THAT SOME LIGHT
FREEZING PRECIP COULD MIX IN WITH THE SNOW. FOR NOW SNOW AMOUNTS AND
UNCERTAINTY OF FREEZING PRECIP LOOK LIMITED ENOUGH TO AVOID A WINTER
WEATHER ADVISORY. RAIN IS MORE LIKELY OVER MOST PORTIONS OF
KLICKITAT COUNTY. FOG WILL PERSIST IN THE COLUMBIA BASIN THIS
MORNING...THEN GRADUALLY IMPROVE. BREEZY CONDITIONS SHOULD PERSIST
OVER THE EXTREME EAST AND CENTRAL PORTIONS OF OREGON WHERE TEMPS
WILL BE RELATIVELY MILD. GKH
