I was running on a treadmill at the gym a few minutes ago, and the AMS president was on CNN talking about the early winter. He said :
Denver was -10 last week and almost 70 this week, at a time when the weather should be hovering around 40
The weather never “hovers” here. If the wind blows from the west, we get downslope heating. If it blows from the east, we get upslope cooling. When I first moved to Boulder twenty years ago, I remember reading a promotional magazine which said Boulder winter weather alternates between frigid and balmy. One of the more popular sayings here is If you don’t like the weather in Colorado, wait a few minutes
Mean Denver high temp is about 45 this time of year, with a range of -10 to 70. Just like it has always been.
