It seems that we get extraordinarily cold mornings on New Years Day. It was -17°F for a low temperature in Bellemont, Arizona today. Two years ago, on New Years Day 2011, it was -30°F. Both times we had fun tossing boiling water into the air and watching it freeze before it hits the ground.
Yeah, sure, folks up north do this all the time in the winter. But, remember, this is Arizona!
