Wednesday marked the first day of fall and while the forecast may not call for freezing temperatures or snow, it won’t be long before the Mile High City is faced with those conditions.  We have in fact already passed the earliest dates Denver has seen freezes and snow so they can arrive at any time. 

Denver has in fact seen snow as early as September 3rd and its first seasonal freeze as early as September 8th.  Those are the extremes however.  On average the first snowfall occurs on October 19th and the first freeze on October 7th.

How will we fare this year?  La Niña conditions are strengthening and the outlook is for warmer than normal temperatures for the next few months.  Colorado weather however doesn’t always follow an established pattern. 

Below is a look at Colorado’s cold season statistics as provided by the National Weather Service.  They provide a bit of historical perspective as to what we might expect this year.
