That's really quite interesting. Up here in the Larimer foothills, there seems to be a real lack of climatological data however my experience over the past 8 years is that mid to late January is typically the coldest. This is very similar to what I experienced in my years of living in Ohio and Indiana. I wonder if there is something inherently different (altitude, LOL) in the short distance between Loveland and 7k+ feet up...or if the past 8 years have generally been anomalous up here. Not the first or last time that I wish there was good climate data up here.
