what is the history of a white Christmas % in your area?
Central New Mexico: 20-30% on average.
Southern New Mexico: 10-20% on average.
Eastern New Mexico: 30% on average.
Northern and NW-ern New Mexico: 10-40% on average (difference in climate).
I say average because there are dead-dry years, and there are shovel-the-driveway-clear-of-6-12"-of-snow-every-week/weekend years (which are far and few, usually every five-ten years, sometimes longer). I have been told by Mom, Dad and Grandmother that southern New Mexico saw 12-36" of snow back in '87/'88. Albuquerque saw less than 5" in one of those years. Lemme bring up some records...
