Denver - If November's weather felt more like September's to you, you were on to something.
November finished with no measurable snowfall for just the ninth time since reliable records began in 1882. It's also the first time Denver will finish snow-free in the month since 2005, and just the second time since 1949.
Temperatures were also seven degrees above average for the month, making it the tenth-warmest November on record. This included a stunning 81-degree temperature on November 27, the warmest November temperature on record in our dear city.
Winter's not dead, but this winter may end up with less snowfall than average, which could be caused by the current weak La Niña pattern in the Pacific.

The primary jet stream pattern over Colorado that led to the warm November. |
A dominating "ridge" of high pressure kept us dry and warm. The jet stream — the narrow ribbon of extremely strong winds about six miles up that dictates a lot of our weather — stayed to our north through most of November. This allowed warm air to consistently flow in from the south and west, and those winds tend to be drier as they roll down the Rockies and into Denver, drying and warming as they do so.
