AFTER A RECORD WET OCTOBER AND NEAR RECORD WARM NOVEMBER...THE
PATTERN CHANGED ONCE AGAIN IN DECEMBER.  A COLDER PATTERN DEVELOPED
ACROSS THE REGION WITH BELOW NORMAL TEMPERATURES AND ABOUT NORMAL
PRECIPITATION ACROSS NORTHEAST WASHINGTON INTO THE NORTH IDAHO
PANHANDLE.  MOST OF THE STORMS THROUGH THE 5TH THROUGH THE 18TH WERE

ARCTIC FREEZE HIT THE REGION ON THE 16TH AND 17TH WITH LOW
TEMPERATURES BELOW ZERO.  ON THE 17TH COEUR D`ALENE DROPPED TO -12F
WITH -7F IN SPOKANE. A STRONGER STORM ON THE 20TH BROUGHT
WIDESPREAD MODERATE TO HEAVY SNOW FOLLOWED BY WINDY CONDITIONS AS A
LOW PRESSURE SYSTEM TRACKED ACROSS SOUTHERN BRITISH COLUMBIA.  ON
THE 23RD A STALLED FRONT BROUGHT A BAND OF HEAVY SNOW FROM THE
PALOUSE UP THROUGH THE SPOKANE AND COEUR D`ALENE AREA AND NORTHEAST
WASHINGTON MOUNTAINS.  CLAYTON PICKED UP 8 INCHES...7 INCHES IN
WORLEY...AND 4-6 INCHES IN THE SPOKANE AREA.  YET ANOTHER STORM
