**Recent forecasts for Denver on August 22 point to an overnight low in the upper 50s to mid-60s°F, driven by typical late-summer radiational cooling at the city’s mile-high elevation combined with a 30-50% chance of thunderstorms.** Official guidance from the National Weather Service and other models shows highs near 90-99°F under partly to mostly cloudy skies, with the minimum temperature most likely falling between roughly 58-66°F as clouds and any storm activity moderate overnight heat loss. Storms could introduce cooler air or localized downbursts that briefly drop readings, which helps explain why the market assigns the highest implied probability (44.5%) to 51°F or below while still spreading substantial weight across the 58-69°F bins. Historical August norms for Denver feature average lows near 60°F, and recent days have featured hot afternoons (mid-90s to low-100s) followed by milder nights in the low-to-mid 60s, with scattered moisture and variable winds. Updated model runs and the proximity of the resolution window keep trader focus on whether overnight cloud cover and precipitation will push the low toward the cooler end of the forecast range or allow clearer skies to support readings closer to 65°F.
