Recent National Weather Service and private model guidance shows Denver highs stabilizing in the low-to-mid 80s for October 7 under persistent high pressure, light southerly flow, and mostly sunny skies that favor strong daytime heating. This consensus directly supports the market’s leading 84–85 °F bin at 44.5 % implied probability, with the adjacent 82–83 °F and 86–87 °F outcomes capturing residual model spread. October climatology places normal highs near 68 °F, so the current warmth reflects an anomalous ridge rather than seasonal norms. With resolution only 48 hours away and no incoming fronts or cloud cover indicated, traders are weighting the latest deterministic runs and ensemble means that have shown little day-to-day drift.
