12th Annual BoulderCAST First Snowfall Contest

Ready to toss that first snowball of the season? Maybe you’ve already waxed your skis, shelled out for that pricey Epic Pass, or jumped the gun on snow tires (again). Well, hold onto your mittens—Boulder’s first big snow could be just around the corner, or not! Mother Nature has been playing tricks on us lately. In the past five years alone, we’ve seen both the earliest and latest first snows on record. But, what will 2026 bring? That’s where you come in.

We’re kicking off our annual First Snow Contest! Please take a look at Boulder’s snowfall history within, then submit your best guess for when the first measurable snow (≥0.1″) will fall in Boulder—and how much will accumulate. The closest guesses will win a selection of prizes!

NOTE: Please only click “Submit” once. It just takes a few seconds to trigger. Thanks!

October 14, 2026 / Ben Castellani / 0 Comments

After months of drought, the Front Range is finally cashing in on a meaningful storm, with Boulder already topping an inch of rain and more moisture still to come. But are the best rains already behind us? A closer look at the storm’s evolving track suggests the answer may be yes, while a hard freeze waits on the other side of this long-overdue autumn gloom.

Colorado Forecast Update: All Systems Go for Beneficial Rain and Snow Throughout the Front Range

October 13, 2026 / Ben Castellani / 1 Comment

After months of watching drought deepen across the Front Range, Colorado is finally getting a storm that could turn the tide. A slow-moving upper low will tap into an unusually rich plume of subtropical moisture and bring widespread rain to much of northern Colorado, along with the season’s first meaningful Mountain snowfall. How much rain can Boulder and Denver expect, who stands the best chance of topping an inch, how low will snow levels drop during the event and which night will bring the season’s first freeze? We break down the latest forecast, timing, rainfall totals, and snow prospects.

This Week in Colorado Weather: October 12, 2026

October 12, 2026 / Andy / 1 Comment

After one final taste of summer warmth on Monday, the weather pattern across Colorado is about to undergo a dramatic shift. A much colder and wetter setup is taking aim at the Front Range this week, with rain returning to the forecast, accumulating snow in the Mountains, and perhaps our first real frost threat of the season by week’s end. While we’ve seen promising storm systems fizzle already this fall, the data continues to suggest this one has a better chance of delivering. We break down the timing of the cooldown, what the latest ensemble guidance says about rainfall totals, and why Friday and Saturday mornings will bear watching for frost.
