WITH A VERY WARM GROUND AND WARM CHINOOK WINDS WHAT LITTLE SNOW FELL QUICKLY MELTED ALLOWING ZERO SNOW DEPTH ON THE GROUND THROUGH THE 30TH OF OCTOBER. SNOW DEPTH AT THE AIRPORT REMAINED ZERO UP UNTIL THE EVENING OF THE 31ST WHEN 0.6 INCHES OF SNOWFALL IN THE AFTERNOON AND EVENING. SNOW DEPTH ON THE GROUND IS ROUNDED TO THE NEAREST INCH SO THE 0.6 INCHES OF SNOW ON THE GROUND ON THE EVENING OF THE 31ST WAS RECORDED AS A SNOW DEPTH OF 1 INCH FOR THE 31ST.

NOVEMBER AVERAGES 0.67 INCHES OF PRECIP WITH ALL OF THAT FALLING AS SNOW IN MOST YEARS...HOWEVER RAIN EVENTS DO HAPPEN AS MANY WILL REMEMBER THE CRIPPLING ICE STORM IN NOVEMBER OF 2010.
