A Complete Failure of Winter Across the West — And What It Means for the Rest of 2026

February 20, 2026 / BoulderCAST Team

Winter may be on the calendar, but it certainly hasn’t been in the air this year. As the West stumbles through one of its warmest, most lopsided cold seasons on record, the signs of a deeper shift are becoming impossible to ignore. From record‑breaking heat along the Front Range to a snowpack crisis unfolding across the entire West, this “winter” has rewritten the rules — and the ripple effects are only beginning to surface. We break down what happened this year, why it matters, and what this complete failure of a winter means for the months 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.

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

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.

Sunday’s record-breaking November heat will give way to a dramatic cooldown on Monday, with temperatures plunging 20 to 30 degrees and wave clouds rolling in over the Front Range. The week ahead stays dry and mostly mild, but a few weak cold fronts will stir up some wind and day-to-day temperature swings. And while the forecast looks quiet for now, ensemble models are starting to hint at a colder, potentially snowier shift next week.

November begins warm and dry; Boulder may challenge its latest first snowfall record

After a stretch of crisp, dry days to end the week, our weather is gearing up for a big warm-up this weekend, with near-record highs favored by Sunday. This developing warm and unfortunately dry pattern looks likely to stick around well into November. With each passing day, the odds grow that Boulder might challenge its record for the latest first snowfall.

Thursday marks the final chapter of our late-summer heatwave, with record-challenging highs expected across the Front Range — but big changes are on the horizon. A cold front arrives tonight, ushering in cooler temps, a return of thunderstorms, and a wetter, more active pattern that could stick around well into next week. From sizzling heat to damaging hail, monsoonal moisture, and a long stretch of below-normal highs, today’s forecast update has a little bit of everything.
