Recent National Weather Service and model guidance for Denver on August 24 shows daytime highs near 90–93 °F but overnight lows with a wide spread from the mid-50s to low-70s, driving the near-even market split between 74 °F or higher and 55 °F or below. Primary uncertainty stems from variable cloud cover and thunderstorm timing, which modulate radiational cooling under Denver’s high-elevation, low-humidity conditions that normally produce large diurnal ranges of 30 °F or more. Clear skies would favor rapid heat loss and lower minima near the 56.7 °F climatological average, while persistent clouds or lingering moisture from afternoon convection could trap heat and push lows well above 70 °F. Recent warm anomalies and shifting steering winds add to model divergence ahead of the next forecast update.
