The Front Range got a welcome surprise overnight as a steady rain event delivered more moisture than many locations were expecting. While today’s clouds, fog, and cool temperatures will keep autumn firmly in charge, they’re also the beginning of a much quieter stretch of weather ahead. Mother Nature will flip the script again with sunshine and temperatures climbing well above normal the rest of the week but don’t get too comfortable. Forecast models are already hinting at our next potential storm opportunity just beyond Halloween.

These weekly forecast posts are published EVERY Monday morning and provide a general overview of the atmosphere and the weather conditions for the week ahead in Front Range Colorado. We give you a heads-up on the major short-term weather features and anything looming down the road.
Last week’s storm finally delivered the kind of soaking rain we’ve been waiting months to see, but don’t get used to it. The atmosphere is shifting back into a familiar pattern this week, with summer-like warmth, abundant sunshine, and another surge of tropical moisture headed toward the Southwest. The catch? Most of that moisture will never make it to the Front Range. In this week’s update, we look at the drought-improving impacts of last week’s storm, why the San Juans are poised to cash in yet again, and whether a late-week cold front can squeeze out a little bit of rain for us before temperatures finally start feeling a bit more like October.

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.
A broad, slow‑moving heat dome has settled over the West, delivering a run of persistent October warmth to the Front Range — but this quiet, summerlike stretch won’t hold forever. This week will be defined by record‑challenging heat aided by downslope flow, and only the faintest chances for a few stray rain showers before a major pattern shake‑up arrives early next week. Ensemble guidance hints at everything from long‑awaited rainfall to the season’s first frost, with even a few early‑season snow scenarios lurking in the spread. Read on for all the details.
A complicated weather pattern is taking shape across Colorado this week, with a deep low pressure system, a surge of tropical moisture, and the remnants of Hurricane Polo all getting tangled up together. For Boulder, Denver and the Front Range, that combination creates some unusually large forecast uncertainties — particularly when it comes to how much rain falls and just how chilly things get by midweek. Meanwhile, southern Colorado is in store for a much bigger soaking, with some impressive rainfall totals showing up in the guidance alongside high peak snowfall. We break down what we know now, what remains uncertain, and when we can finally expect this week’s definitively gloomy weather to break and sunshine to return.
Despite an active monsoon that refuses to quit, Boulder has remained stubbornly dry with just 18% of normal precipitation during September which has been anything but typical. This week will keep the theme alive: plenty of monsoon flow, impressive moisture surges, and even a pair of dancing hurricanes in the Eastern Pacific, yet northern Colorado will still struggle to squeeze out meaningful rainfall again. We break down why the pattern looks so active on paper, why the Front Range keeps missing out, and what late‑week changes might finally nudge storm chances upward.
September is finally starting to feel like September again — but not before one last burst of late‑summer heat today. A sharp pattern shift arrives tonight, opening the door to cooler temperatures, daily storm chances, and a midweek surge of moisture that could make things interesting across parts of Colorado. We’ll also check in on a small wildfire in the San Luis Valley, track where the heaviest rainfall is most likely to fall, and look ahead to a weekend that may line up perfectly with rapidly peaking fall colors. Read on for all the details.
