I'm sure some on here may believe the National Weather Service in Denver last week was wrong. The NWS published report by the National Weather Service stated that 2013 was the coldest year in Colorado since records have been kept and so far the first six months of 2014 are even colder. Colorado records by the National Weather Service only go back to 1906.
I believe it from our ranch records on both on our ranches. Our ranch records record the actual single coldest winter days happened in the 1960's, but on average the yearly temperature averages, combining summer and winter, are now cooler than the 60's. In 1962 we recorded two nights when the temperture dropped to below minus 50 degrees. We still get a number of nights of minus 40-45 degrees every year, even more often than 40-50 years ago, and more summer nights now with frost on the grass before sunup than we did years ago.
