DECEMBER 2014 STARTED OFF ON A COOL AND DRY NOTE OVER NORTHEAST
WASHINGTON AND THE NORTH IDAHO PANHANDLE.  A MUCH MILDER PATTERN
DEVELOPED ON THE 4TH THROUGH CHRISTMAS EVE WITH OCCASIONAL RAIN.
DURING THIS TRANSITION FROM COOL TO WARM...A PERIOD OF LIGHT SNOW
OCCURRED ON THE 4TH IN SPOKANE WHICH CHANGED TO FREEZING RAIN.
TEMPERATURES WERE EXCEPTIONALLY WARM ON THE 10TH WHERE SPOKANE
AIRPORT REACHED 57 DEGREES...WITH A BALMY 63 AT FELTS FIELD.  THE
WETTEST SYSTEM DURING THIS PERIOD PASSED THROUGH ON THE 20TH WITH
0.50 INCHES OF RAIN IN SPOKANE...AND 1.20 INCHES IN CLAYTON.

ON CHRISTMAS EVE A COLD FRONT BROUGHT LOWERING SNOW LEVELS TO NEAR
2500 FEET WITH RAIN CHANGING TO SNOW AT THE SPOKANE AIRPORT WITH
ABOUT A HALF INCH OF ACCUMULATION.  THIS SYSTEM BROUGHT MUCH HEAVIER
SNOW AMOUNTS TO THE CENTRAL PANHANDLE MOUNTAINS WITH LOOKOUT PASS
PICKING UP 11 INCHES.

THE MONTH ENDED WITH MUCH MORE WINTER LIKE CONDITIONS.  ON THE 27TH
A COOLER SYSTEM CAME DOWN FROM THE GULF OF ALASKA BRINGING 2 INCHES
OF SNOW TO SPOKANE...WITH MUCH HIGHER AMOUNTS TO THE EAST. COEUR
D`ALENE RECEIVED 6 INCHES WITH 9 INCHES IN KELLOGG.  LOOKOUT PASS
RECEIVED 17 INCHES.  THE NORTH IDAHO PANHANDLE AND NORTHEAST
WASHINGTON MOUNTAINS PICKED UP BETWEEN 3 TO 7 INCHES FOR MOST AREAS.

A VERY COLD ARCTIC AIR MASS MOVED INTO THE AREA TO FINISH OUT THE
MONTH.  DEER PARK DROPPED TO -7 DEGREES FAHRENHEIT ON THE 30TH.

A COUPLE RECORDS WERE BROKEN DURING THE MONTH AT THE SPOKANE
AIRPORT.  ON THE 11TH A HIGH TEMPERATURE OF 56 DEGREES BROKE A
RECORD FOR THE DATE.  ON THE 10TH...A LOW TEMPERATURE OF 45 DEGREES
