This post had major contributions from at least two members of our team. The more meteorologists the better, right?
If you thought Monday’s sunshine was the start of a quiet week, think again. The next 48 hours will bring a dramatic shift in our weather —starting with breezy but pleasant conditions Tuesday, then escalating into a powerful downslope windstorm with heightened fire danger on Wednesday. And just when you think it’s wrapping up, a sharp cold front will crash the party with blustery conditions and even a chance for rain and snow Wednesday evening.
We’ll break down what to expect, where the strongest winds will hit, and how this event stacks up against the day of the Marshall Fire. Plus, we’ll look at the potential for Xcel power shutoffs (spoiler: it’s going to be happen).
Apologies for the delay, but with Boulder’s record-shattering latest first snow of the season officially in the bag back on November 29th, it’s time to announce the winners of our 11th Annual First Snowfall Contest. Were you one of them?
Winter finally showed up in style this week along the Front Range. After a sluggish start to the season, our first true snowstorm delivered nearly 18 hours of steady flakes, painting Boulder, Denver, and much of Colorado in white. But this wasn’t just a simple upslope event—there were some fascinating atmospheric twists that kept the snow machine running longer than expected. We review the storm setup and snowfall totals which greatly favored the western side of the Metro area including Boulder.
A few snowflakes fell across the area Sunday evening with some jet-forced snow bands around. These were largely south of Denver leaving just a trace of snow for most of us. The Mountains made out better with several inches of orographic snow piling up under moist northwesterly flow. We briefly review both the snow totals from this single storm and the seasonal ones.
Boulder’s long snow drought has finally ended—just shy of a record streak. An Arctic front swept through early Saturday, dropping temps fast and delivering the season’s first flakes. Boulder picked up 0.3″, the latest first snowfall ever recorded in the city and it wasn’t even close. Curious how our forecast stacked up and what’s next? Spoiler: Another round of snow is already knocking on the door for Sunday.
It’s been a tricky week for the weather models — and for us forecasters trying to make sense of it all. Our latest storm system has kept everyone on their toes, thanks to a complicated dance between two low-pressure systems across the Southwest. Each new model run seemed to rewrite the story, with big swings in outcomes and plenty of disagreement between guidance. But now that the storm is closing in, confidence is finally improving: we’re looking at a light precipitation event for the Front Range, with rain the only worry across the lower elevations.
October 2025 was definitively warm and dry throughout the Front Range with the primary storm track remaining well north across Wyoming and Montana. The only real precipitation event during the month occurred on October 6th with some locations picking up more than one half inch of rain. Our first frost of the season occurred about two weeks later than normal, and to this day we’re still waiting for those magical first snowflakes across the lower elevations. Here’s a quick and colorful graphical recap of our weather during October and how it relates to climatology.
