December 2020 was marred by a series of weak storm systems that resulted in very little snowfall. This lack of moisture further exacerbated the ongoing drought in Colorado and dashed the hopes of many for a white Christmas in our area. Overall, it was yet another warm and fairly dry month. In fact, this was the sixth month in a row that ended warmer and drier than normal. Here’s a quick and colorful rundown of our weather during December and how it relates to climatology.

These posts contain some discussion of the white stuff, whether it be mountain snow pack or a Front Range snowstorm.

We hope that each and every one of you had a great holiday so far and that it continues into the New Year. This week’s weather will feature light snow accumulations Monday into Tuesday alongside chilly temperatures for much of the week ahead. We’re also watching another system later in the week which could ring in the New Year with more snow. Read on for all the details.
We take a broad look at White Christmas occurrences in Boulder’s historical record and discuss why Christmas Day, out of all days, has the highest probability of snow on the ground. We also give our White Christmas forecast for this year.
After a breezy last couple of days, the holiday week starts out calm and mild for the first official day of winter. A midweek cold snap will ensue, along with a slight chance of snow showers. The Christmas forecast is looking dry, although there are signs that a more active pattern could develop for late December.

In an almost identical setup to what transpired this past Monday, another weak storm system will progress across Colorado Thursday night into Friday afternoon. Once again the storm’s track and speed will greatly limit snowfall potential in the Denver Metro area. However, there will be a sprinkle of accumulation to close out the week in some locations. Let’s quickly take a look.
