Winter Storm Recap: That brief burst of heavy snow was great, but the drought marches on

April 18, 2026 / BoulderCAST Team / 0 Comments

Friday delivered one of those classic Colorado curveballs. The storm showed up fashionably late, then hit harder than expected once it finally got going. It left behind a fast‑melting blanket of spring snow and cleared out almost as quickly as it arrived. In today’s update, we break down the wild midday burst of snow, take a look at how the forecast held up, and highlight why the real headline may have been what happened — or didn’t happen — after the flakes stopped.

March 2026 Graphical Weather Review: The warmest March on record by a massive margin (and warmer than all but a few Aprils)

April 3, 2026 / Ben Castellani / 2 Comments

March 2026 delivered one of Colorado’s most jarring spring months on record with temperatures skyrocketing to unprecedented levels as the region shattered long‑standing warmth records for weeks on end. Western snowpack rapidly declined during this multi-week heatwave, reaching historic lows in a majority of basins across the West, including every major basin in Colorado. Brief interjections of snow occurred during the month across the Front Range, but most the state ended with well below normal precipitation. Here’s a quick and colorful graphical recap of our weather during March and how it relates to climatology.

This Week in Colorado Weather: March 30, 2026

March 30, 2026 / Andy / 0 Comments

March is supposed to bring hints of spring, not the kind of heat that rewrites the record books and eats away snowpack like it’s June. Yet here we are again, recapping another weekend of astonishing warmth, more broken records, and a dire Westwide snowpack situation that has become genuinely alarming. We walk through just how extreme the heatwave has been, why Colorado’s water outlook is now in uncharted territory, and what the coming early April pattern shift might (or might not) do to slow the damage that’s already been done. Let’s dig in.

Winter Storm Recap: From Underwhelming Winds to Overnight Snow

March 15, 2026 / Ben Castellani

Saturday’s storm didn’t quite live up to its wind hype, but it still delivered a sharp overnight front and a quick burst of convective snow before sunrise on Sunday.

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.

Front Range Snowfall Totals: February 17-21, 2026

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.
