Recent National Weather Service guidance highlights a sharp cooldown for Denver on August 4 driven by a frontal passage that follows peak heat on preceding days. Model consensus points to north-northeasterly flow advecting cooler, drier air behind the boundary, with afternoon highs most likely settling in the upper 70s to low 80s under partly to mostly sunny skies and light winds. Afternoon convection remains possible but limited, reducing the chance of strong downslope warming. This setup aligns with the market’s tight clustering around 78–81 °F, reflecting traders’ assessment of ensemble spreads and typical post-frontal temperature drops of 15–25 °F observed in similar late-summer transitions. Updated model runs and the next NWS forecast discussion will refine the precise maximum before resolution.
