A quick round of overnight snow is already over and done with in the area as of Monday morning, but it’s just the opening act in a busy week of weather across the Front Range. Several cold fronts are lined up to keep temperatures bouncing around, including a late‑week Arctic surge that could deliver the coldest air of the season and a chance for additional snow. Read on as we break down the timing of at least three different cold fronts, the associated wind and fire‑weather concerns, and what to expect as that Arctic air barrels in later this week.

2025 was one of those years where Boulder’s weather never seemed content with a single storyline. We opened with a bitter Arctic punch that delivered our coldest January in nearly two decades, only to swing into a summer packed with 90°+ heat, smoky afternoons, and the hottest day since 2012. The monsoon showed up often but rarely with much enthusiasm, fall dried out in a hurry, and our first snow didn’t arrive until November 29th — the latest on record by a country mile. Now that the dust (and smoke, and snow) has settled, we’ve pulled together a full graphical recap of the temperature swings, precipitation quirks, record‑setting moments, and long‑term trends that defined Boulder’s and Colorado’s atmosphere in 2025. If you want the full story behind the chaos — and a clearer picture of where 2025 truly landed — this is a fun one to dive into. Be warned, there really are 100 charts and visuals to explore. Enjoy!
Warm, gusty weather is kicking off the first full week of 2026, but the atmosphere has a few twists lined up as we move toward the weekend. A stubborn ridge will keep us mild early on as downslope winds ramp up fire concerns. However, a developing trough later in the week will turn us much colder — with even the possibility of snow for Boulder and Denver if the storm track cooperates. The details are still evolving, but there’s plenty to watch in the days ahead.
After a quick burst of weekend snow and our coldest temperatures since early December, the week ahead turns much quieter across Colorado. Temperatures will climb steadily as Boulder and Denver stay dry into the New Year, while the Mountains prepare for a well‑timed round of snow for the holiday weekend. We’ll walk you through the day‑to‑day weather this week, where the snow will fall, and check in on long‑range guidance which still isn’t advertising much in the way of winter for eastern Colorado.
December has been anything but typical along the Front Range, with Boulder shattering warmth records and enduring weeks of bone‑dry weather that have fueled fire danger and stressed our local trees. As we head into Christmas, the holiday will feel more like patio season than sledding weather, with record highs likely and no snow available outside of the Mountains. But don’t pack away the winter gear just yet—a sharp cooldown and even a chance for light snow are on the horizon this weekend. We take a closer look this historically warm and dry December, the scorching Christmas forecast, and peek ahead to what’s next.
As we head into what’s normally the coldest stretch of the year along the Front Range, the atmosphere has other plans. Instead of Arctic air and snow globe conditions, we’re staring down a week of springlike warmth, fire weather concerns, and multiple shots at breaking long‑standing temperature records—including on Christmas Day. We’ll walk you through why this pattern is so unusual, what it means for Boulder and the Foothills, and where you can still find real winter this week if you’re craving it.
Winds are howling across the Foothills this morning, with gusts topping 70+ MPH and fire danger at historic levels. For the first time ever, Colorado is under a Particularly Dangerous Situation Red Flag Warning—an extraordinary designation from the National Weather Service. While Boulder itself could dodge the absolute most extreme winds, conditions remain somewhat uncertain overall, and things will definitely be highly volatile in the Foothills. We breakdown the latest model updates and step through how this dangerous Friday will unfold across the area.
