Latest National Weather Service and private-model guidance for Denver points to an overnight low in the mid-60s on August 28 under partly cloudy skies and light southwesterly flow, with daytime highs near 95 °F limiting radiational cooling. Dew points near 50 °F and minimal cloud cover overnight support modest temperature drops after sunset, while the absence of a strong frontal passage keeps the air mass stable and above seasonal norms. Ensemble spreads remain tight, producing the tight clustering of market-implied probabilities around the 64–69 °F bins; any increase in low-level moisture or unexpected wind would favor the lower end of that range, whereas clearer conditions could push readings slightly higher before dawn.
