Trader consensus on Polymarket reflects National Weather Service guidance and ensemble model outputs from GFS and ECMWF, implying a highest temperature near 60°F in Denver on April 4 amid a transition from March's record-shattering heat—highs topping 87°F—to cooler conditions driven by an approaching upper-level trough. This system introduces mid-level cool air advection, increased cloud cover, and light precipitation risks, tempering highs from current 80s to the upper 50s-low 60s range, aligning with the April 4 climatological normal of 60°F at Denver International Airport. Recent 48-hour model runs show spread in trough depth and timing, boosting 62°F or higher to 41.5% while distributing probabilities across 56-61°F bins; watch for afternoon NWS updates and evening 00Z model refreshes that could refine land surface forecasts.
