National Weather Service forecasts point to a high near 97°F in Denver on August 7 under sunny skies, establishing the primary driver behind the market’s tight clustering around 96–99°F. Recent hot conditions, including upper-90s to low-100s readings earlier in the week amid persistent heat and occasional wildfire smoke, have kept temperatures elevated relative to August climatology. Subtle differences between the leading bins reflect model sensitivity to afternoon wind shifts, smoke-induced radiative effects, and exact timing of peak heating. With resolution imminent, traders are weighting official guidance and short-range ensemble consensus while acknowledging that minor forecast adjustments could shift the outcome within the narrow 96–99°F range.
