It's not that the Front Range of Colorado continues to experience above average temperatures, it's that it gets hotter sooner in the day and stays hotter later.
This summer is much more pronounced. I've never felt anything like it. The weather in Colorado has a lot of variability in it, but not this summer. It's hotter for longer periods of the day. It's much windier during longer stretches, and it's much drier.
If I recall my brief stay at NCAR and various IPCC reports, this is what was predicted. Unfortunately this is only the beginning.
