The pattern is gradually shifting across Colorado, with lingering moisture keeping Thursday cool and cloudy before drier, warmer weather settles in for the weekend. Beyond that, the forecast becomes much less certain as the first significant autumn trough approaches from the west and potentially interacts with the remnants of Hurricane Polo across the southern Rockies. There are several possible outcomes for early next week in the Front Range, ranging from a quick cooldown with some showers to a much wetter setup. We break down what the models are showing, what we’re confident in, and what remains uncertain.

Premium BoulderCAST Daily – Tue 09/22/26 | Subtropical Plume Arrives, Rainfall Still Hard to Come By
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.
Boulder County just rolled back its fire restrictions—right as we close the book on one of the hottest, driest, most fuel‑parching summers in recent history. The county says “improved conditions” justify easing the bans, yet rainfall has been almost impossible to come by within county limits, Extreme Drought now blankets 84% of the county, and fuel moisture is objectively worse today than when restrictions were last ramped up back in late June. It begs a very reasonable question: what exactly has improved? We break down the data behind the decision and examine why Boulder County’s fire environment remains primed as we step closer to autumn—historically one of our area’s most volatile fire seasons in recent years.
