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

Winter Storm Recap: Overnight snow bands coated the Front Range in fluffy flakes, reminding us it can indeed snow in the winter here

December 28, 2025 / Ben Castellani

A few wobbly overnight snow bands dropped a light, fluffy coating of powder across the Front Range—right on target with our forecast. We break down where the bands hit, why the snow ratios were so sky‑high, and what this tiny event means for our growing seasonal deficit. We also look ahead to the warm, dry pattern set to carry us into the New Year.

Winter Weather Update: Snow chances have fizzled, but a sharp cold front will still pack a wintry punch Saturday night

December 27, 2025 / Ben Castellani

After a stretch of December warmth so extreme it rewrote some record books across the Front Range, we’re finally staring down a pattern shift—though not quite the snowy one we initially hoped for. A pair of cold fronts will bring a sharp temperature drop, a few chances for rain and snow, and at least the feeling of winter back to Boulder and Denver. The details have changed quite a bit in the last 24 to 48 hours, but we’ll walk you through what’s still on the table, what’s no longer likely, and where a few surprises could still sneak in Saturday night.

Why is Christmas Day one of the whitest days of the year in Boulder?

This Christmas will be a scorcher across the Front Range with temperatures soaring towards record highs near 70 degrees, but snow is often part of the equation here on Christmas, whether falling or on the ground. We take a broader look at White Christmas occurrences in Boulder’s historical record and discuss why Christmas Day, out of all days, has one of the highest probabilities of snow on the ground here.

The Front Range heads into a record‑warm, snow‑starved Christmas after an unusually dry fall

December 24, 2025 / BoulderCAST Team

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.

This Week in Colorado Weather: December 22, 2025

December 22, 2025 / Andy

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.

Wednesday Windstorm Update: Significant downslope winds and high fire danger expected from late morning into early evening

December 17, 2025 / Ben Castellani

Hold onto your hats, Colorado—today’s forecast isn’t just another breezy afternoon. A fast‑developing mountain wave event is lining up to deliver some of the strongest winds we’ve seen in quite some time, with Boulder squarely in the bullseye for this event. We’re talking winds that can go from calm to extreme in minutes, near-critical fire danger with every gust, and even the likelihood of planned and unplanned power outages. Add in mountain snow squalls and a sharp cold front tonight, and it’s definitely a busy day in Colorado weather. Read on for the full breakdown of timing, impacts, and what you need to know to stay safe as the event unfolds.

Colorado Forecast Update: Damaging winds and near-critical fire danger for the Front Range on Wednesday, planned Xcel power shutdowns are highly likely

December 16, 2025 / BoulderCAST Team

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).

This Week in Colorado Weather: December 15, 2025

December 15, 2025 / Ben Castellani

The Front Range has been defined by relentless warmth, gusty winds, and bone‑dry conditions of late—and that theme isn’t breaking anytime soon. Even with a strong cold front charging through midweek, the cooldown will be pitiful, dropping us only back to “normal” while lasting only a single day, and it comes at the price of near‑critical fire danger beforehand. With highs hovering near or above 60° almost every day leading into Christmas and precipitation chances close to zero, a brown holiday is essentially guaranteed for the Boulder–Denver area. Read on for our full outlook of our weather heading into the holiday period.
