...CHANCE OF SNOW, FREEZING RAIN, OR SLEET OVER PORTIONS OF  
EASTERN WASHINGTON AND EASTERN OREGON TONIGHT THROUGH MONDAY  
MORNING...  
 
A WEAK WARM FRONT WILL TRAVEL EAST OF THE CASCADES LATE THIS  
AFTERNOON AND TONIGHT. SNOW LEVELS ARE NOT EXPECTED TO RISE  
SIGNIFICANTLY WITH THE APPROACHING SYSTEM. THEREFORE, MOST OF THE  
MOUNTAINS AND HIGHER VALLEYS WILL OBSERVE SNOW OVERNIGHT. HOWEVER,  
WARMER AIR WILL OVERRIDE COLD AIR AT THE SURFACE WITH A POTENTIAL  
FOR LIGHT FREEZING RAIN OR SLEET. WINTER WEATHER ADVISORIES ARE IN  
EFFECT FOR SOME AREAS IN EASTERN WASHINGTON AND EASTERN OREGON  
THAT HAVE THE BEST POTENTIAL FOR ICE ACCUMULATIONS. THOSE AREAS  
NOT UNDER A WINTER WEATHER ADVISORY WILL HAVE A CHANCE OF A WINTRY  
MIX OF SNOW, SLEET, OR FREEZING RAIN...ALTHOUGH ACCUMULATIONS  
WILL BE MINIMAL. IF TRAVELING TONIGHT AND MONDAY MORNING ACROSS  
EASTERN WASHINGTON AND EASTERN OREGON, BE PREPARED FOR WINTER  
DRIVING CONDITIONS. ANTICIPATE SLICK ROADS IN MOST AREAS.
