These posts contain some discussion of the white stuff, whether it be mountain snow pack or a Front Range snowstorm.
Clouds roll in Thursday as a compact storm system approaches from the southwest—but don’t expect much more than a few sprinkles and high mountain snow. Boulder and Denver stay mostly dry, with mild temps in the 60s and a sunnier stretch ahead for Friday and Saturday. A stronger trough will arrive Sunday into early next week, bringing gusty winds and a taste of cooler fall air, but once again little in the way of meaningful rain or snow east of the Mountains. Read on for all the details.
This week’s forecast is anything but boring in the Front Range. A fast-moving autumn storm is stirring up the atmosphere on Monday with jet-driven Mountain snow, powerful downslope winds, and a fire-weather setup that demands caution. And once the winds die down? A hard freeze will slam the door on the growing season for the entire area Monday night. Read on for a full breakdown of the very active weather unfolding in Colorado on Monday, plus a peek towards the quieter days ahead.
This week will feature a dynamic stretch of autumn weather in the Front Range including dramatic temperature swings, another influx of tropical moisture, and a midweek warm surge that could push us near 80°F. Following all of that, a late-week trough will bring a chilly front and our best shot at rain, plus there’s a weekend wildcard that might even produce some snow. Curious what’s driving all this weather? We break down the atmospheric setup, moisture sources, and ensemble model data in our latest weekly outlook.
11th 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 2025 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!
