Will the minimum temperature be 34-35° on Apr 26, 2026?

The strongest evidence against the 34-35°F bin is the current temperature combined with the lack of remaining cooling time. Multiple independent analyses confirm Denver is sitting at 37°F as of 4:35 AM MDT. With sunrise scheduled for 6:05 AM, the atmosphere has less than 90 minutes to produce a 2-3 degree drop. Furthermore, mostly cloudy skies are currently acting as a thermal blanket over the Denver area. This cloud cover severely inhibits the radiational cooling necessary to drive the temperature down. Without clear skies to allow surface heat to escape, the cooling rate will remain sluggish, keeping the temperature safely above the target bin. Finally, the National Weather Service forecast consensus strongly points to a daily low of 36°F. Narrow 2-degree bins are inherently difficult to hit, and fading them is a high-conviction strategy when the forecast floor sits just outside the range. It's highly improbable that the temperature drops into the mid-30s given the 36°F forecast, 37°F current observations, and insulating clouds.

The primary risk to the NO position is the underlying dewpoint, which currently sits between 31°F and 33°F. This provides a physical floor that is well below the target bin. If the cloud deck clears unexpectedly before sunrise, radiational cooling could rapidly accelerate, dropping the temperature from 37°F straight into the 34-35°F range. Additionally, Denver's microclimates and cold air drainage from the Front Range often cause localized temperature drops at the KDEN airport sensor that defy broader metro area forecasts. A sudden shift in drainage winds could cause a sharp, short-lived dip at the official sensor just before dawn. There's also a speculative, uncorroborated report that the temperature may have briefly touched 35°F at 12:53 AM before warming back to 37°F due to incoming clouds. If this single observation is accurate and recorded in the final NWS daily climate report, the minimum temperature would already be locked into the target bin, resulting in an automatic YES.
