Winter Storm Recap: A welcomed overachiever for portions of Denver and a healthy dump of moisture for all

March 7, 2026 / BoulderCAST Team

Our late‑week spring storm delivered a far more impressive performance than early models suggested. What looked like a modest, fast‑moving system slowed down, reorganized, and ultimately dumped a surprisingly healthy swath of heavy, wet snow across the Front Range. From booming Foothills totals to a rare over‑performance at DIA, this one had plenty of action worth unpacking. Let’s take a look at how the storm evolved, where our forecast missed the mark, and just how quickly we’ll be warming back into the 70s.

This Week in Colorado Weather: February 23, 2026

February 23, 2026 / Ben Castellani

As February limps toward the finish line, Colorado’s “winter” continues to behave like anything but. Last week the Mountains cashed in on a burst of Pacific moisture while the Denver Metro area stayed stubbornly snow‑starved. The week ahead brings more of that same split personality—warmth, wind, fire danger, and another round of Mountain snow. We break down the lopsided snow totals from last week, the updated but still troubling snowpack numbers, and discuss why this week will be so darn warm and windy again in the Front Range.

Much-needed snow piled up across all of the Mountains of Colorado this week, but once again Boulder and Denver missed out on almost all of the action.

January 2026 Graphical Weather Review: Another mild month on the Front Range with winter still nowhere to be found

February 5, 2026 / BoulderCAST Team

January 2026 wrapped up feeling more like an early taste of spring than the heart of winter along the Front Range, with warm spells, frequent downslope winds, and only fleeting brushes with snow. Boulder spent much of the month running well above normal, dodging storm after storm as the real winter weather stayed locked in the Mountains and across the eastern half of the country. Here’s a quick and colorful graphical recap of our weather during January and how it relates to climatology.

A fleeting brush with winter may have swept across the Front Range this past weekend, but the atmosphere isn’t planning to stick with the theme for long. That sharp Arctic plunge—while refreshing for snow lovers—was more of a brief interruption than a true turning point. A closer look at the pattern ahead shows Colorado snapping right back into its now‑familiar routine of warm afternoons, bone‑dry air, and a statewide snowpack sitting at record‑low levels. Winter may have knocked on the door, but it certainly isn’t moving in.

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.

Winter Storm Recap: 2026’s first snowfall is over and it won’t stick around long

January 9, 2026 / Ben Castellani

A tandem of low pressure systems — one warm and moisture‑rich, the other colder and more dynamic — teamed up just enough to deliver a surprisingly efficient burst of snowfall across the Front Range to end the week. We break down how this two‑part event unfolded, why the timing mattered so much, and where our forecast over‑ and under‑performed. Continue reading

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.
