Recent National Weather Service and model guidance indicate a Tuesday high in Denver near 85–89 °F, aligning with climatological norms for late August and explaining the market’s concentration on the 86–89 °F bins. Persistent monsoon moisture supports scattered afternoon thunderstorms that can limit peak heating through cloud cover and evaporative cooling, while light easterly flow and surface dew points in the 50s °F moderate temperatures. Ensemble spreads remain modest, with only modest upside risk if storms develop after peak heating or if downslope warming strengthens. Updated model runs and NWS forecast discussions over the next 24 hours will refine the exact maximum and any adjustments to implied probabilities.
