watering trees now in the winter (?)
I have two mature silver maples, two apple trees, and two mature blue spruce. Should I be watering these trees now since it has been unusually warm this December? Is so, how much?

Yes, it's always smart to water your trees and conifers approximately once a month through the winter when we don't have precipitation. We have had a very dry autumn and early winter in Denver so supplemental watering is especially needed this year.
Here are some tips from Plant Talk Colorado about winter watering: http://planttalk.colostate.edu/topics/trees-shrubs-vines/1706-fall-winter-watering/
