Forecast models from the National Weather Service and private sources show Denver's overnight low on October 11 likely falling between the mid-50s and low-60s Fahrenheit, with southerly winds and increasing cloud cover limiting radiative cooling under a mild air mass. Recent observations indicate above-average temperatures driven by persistent southwesterly flow, reducing the chance of sharp overnight drops typical for mid-October. Traders appear to weigh slight model spreads in cloud timing and boundary-layer mixing, which can shift the minimum by several degrees, against historical climatology where lows near 45°F are more common. Updated guidance from the NHC-equivalent regional offices and next model runs will clarify whether conditions trend toward the warmer or cooler end of current bins.
