Recent National Weather Service and local forecasts for Denver on September 26 indicate sunny to mostly sunny skies with a high near 83°F and minimal precipitation risk, driving the strong market consensus around 82-83°F. Clear conditions and light southerly winds support efficient daytime solar heating at the mile-high elevation, where reduced air density allows temperatures to climb more readily than at sea level. Model agreement on stable high pressure and dry air masses reinforces this range, consistent with typical late-September climatology absent any anomalous warmth or cloud cover. Traders appear to weigh these official projections heavily, with adjacent bins capturing residual forecast uncertainty in exact peak readings.
