Trader consensus on Polymarket assigns a 51% implied probability to a high of 48°F or higher in Chicago on April 2, reflecting the latest National Weather Service forecasts and ensemble model runs from GFS and ECMWF, which converge on daytime highs near 48–50°F at O'Hare International Airport amid partly cloudy skies and light southerly winds. This positioning stems from a recent shift in the upper-level pattern, with a weakening trough over the Midwest allowing mild air advection after cooler late-March conditions, though lingering cloud cover from a passing weak front caps temperatures below the 54°F seasonal normal. Model uncertainty persists around boundary layer mixing and precipitation chances, distributing probabilities across mid-40s bins; watch for NWS Chicago's afternoon forecast update and tomorrow's 00Z model refresh for potential adjustments as resolution approaches.
