**Trader consensus on Polymarket overwhelmingly favors a high temperature of 50°F or higher in Denver on April 28 (100% implied probability), driven by the National Weather Service (NWS) Boulder forecast consensus projecting a daytime peak near 55–58°F under mostly cloudy skies with isolated showers.** Current observations at Denver International Airport show midday temperatures already reaching 48°F, consistent with model guidance from GFS and ECMWF ensembles indicating weak upper-level troughing yielding mild advection and limited cooling potential. April climatology supports this, with historical highs averaging 60°F and rare dips below 50°F on clear-tracking days. Realistic challenges include unexpected reinforcement of northerly winds or persistent thunderstorm activity capping peaks below 50°F, though low-level moisture profiles and steering currents make this unlikely; watch afternoon NWS updates for final model runs.**
