Last week’s highly-anomalous Arctic blast delivered the goods in terms of record cold and a decent snowfall across the Front Range. We discuss a few different aspects of this particular Arctic outbreak which make it stand out against Boulder’s 122 year historical record.

Wednesday sure will be an appropriate first day of winter across the Front Range — the coldest airmass in more than a decade will flood our area! After a warm and windy afternoon of elevated fire danger, the well-advertised Arctic front will blow through by early evening accompanied by tumbling temperatures and pockets of heavy snow. We discuss a few small changes to the forecast including why we are bumping up the expected snowfall totals a tad across the area. Let’s talk bitter cold and white stuff!
A doozy of a forecast will unfold this week as extremely cold Arctic air overtakes the Front Range late on Wednesday accompanied by a quick shot of fluffy snowfall. However, the main story will be the bitter cold with wind chills dropping to dangerous levels for an extended period. This may be the coldest air to reach our area in decades. We discuss the timing of the powerful front, just how cold it will get and give our early thoughts on potential snowfall accumulations.
November 2022 finally broke the streak of four consecutive months of above normal temperatures in Boulder — and by a considerable margin. The bitter cold air led to several fluffy snow events across the area which aided in etching this November as a top ten snowiest and coldest November for the city. Here’s a quick and colorful graphical recap of our weather during November and how it relates to climatology.
We concluded the already very snowy and cold month of November with even more snow and cold on Tuesday. A brief period of moderate to heavy snow led to a slick morning commute in many areas, with some of the coldest air of the season filtering in as the snow cleared out. Let’s take a look at the snowfall totals across the area, review November’s weather so far, and discuss the largely pleasant weather that lies ahead.
October 2022 Graphical Weather Review: Not as bone-dry as last October, but still dry & warm overall
October 2022 was yet another warm and dry month for the Front Range as drought expanded across the state and our precipitation deficit for 2022 grew further. Denver and Boulder both saw later than normal first snowfalls and first freezes. There were no major heatwaves or cold snaps to speak of during the month either. Here’s a quick and colorful graphical recap of our weather during October and how it relates to climatology.
Much-needed rain and snow fell across the Front Range on Thursday as a quick-moving storm raced across the state. Though temperatures remained entirely above freezing in Boulder and Denver, some embedded heavier pockets of snow allowed for minor accumulations to occur on the grass in spots, including at the official climate station in Boulder. This made for an interesting but somewhat underwhelming first snowfall of the season for many. We recap the storm, take a look at the snowfall totals across the region, announce the plethora of winners to our 2022 First Snowfall Contest, and look ahead to our next chance of snow.
September 2022 followed the trend of the rest of the summer as another hot and somewhat dry month across the Front Range. The month entertained one of the longest and most intense heatwaves for so late in the season. Rainfall was below normal and there was no snow during the month. Smoke from out of state wildfires was also a theme at times. Here’s a quick and colorful graphical recap of our weather during September and how it relates to climatology.
