**Forecast consensus from NWS and private models points to a mostly sunny to partly cloudy day with afternoon heating driving the daily maximum into the upper 80s, producing the current market tilt toward 88-89°F (45%) and 86-87°F (30.5%).** Denver’s mile-high elevation moderates absolute values, but clear skies and weak winds allow strong daytime insolation to push surface temperatures 5–10°F above the seasonal normal of ~86°F. Latest NWS guidance and ensemble runs show highs of 85–89°F, with 30–40% afternoon thunderstorm chances that could cap the peak if early convection develops. Recent model trends have held steady in this range, with limited spread across guidance, which explains why bins below 84°F or above 91°F carry single-digit implied probabilities. The resolution hinges on the official 24-hour maximum at the NWS Denver observation site, so any last-minute shift in cloud cover or storm timing remains the key variable traders are pricing.
