Trader consensus on Polymarket favors a high temperature of 52°F or higher at 41% implied probability for Chicago on April 1, driven by National Weather Service climatological normals of 53.3°F and NOAA's spring 2026 outlook predicting warmer-than-average conditions amid a late-March warming trend with highs reaching the 70s. Current short-range guidance from operational models like GFS and ECMWF shows ensemble means in the low to mid-50s°F under ridging aloft and light southerly flow, though variability from potential weak frontal passages introduces uncertainty reflected in spread across 48-51°F outcomes. New 12Z model runs and NWS updates expected March 31 could shift odds as resolution nears.
