This Week in Colorado Weather: September 14, 2026

September 14, 2026 / Andy / 0 Comments

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 Rolls Back Fire Restrictions as Extreme Drought Persists

September 11, 2026 / BoulderCAST Team / 0 Comments

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.
