Colorado mountain regions have transitioned from record-breaking heat waves toward weather patterns influenced by monsoonal moisture. Initially, the state faced temperatures up to 10 degrees above normal, creating concerns regarding dry thunderstorms and flash flooding in areas with hydrophobic burned ground.

By September, the Western Slope continued to experience warmer-than-normal temperatures, with highs sitting 5-7 degrees above seasonal norms. Monsoonal moisture remains a factor, contributing to scattered showers and windy conditions. Long-term forecasts suggest a persistent trend of warmth, with a 33-50% chance of above-normal temperatures continuing through the next 30 days.
