Trader consensus on Polymarket heavily favors a high temperature of 57°F or below in Chicago on April 4 (57% implied probability), driven by the National Weather Service's latest point forecast projecting a daytime maximum near 57°F under mostly cloudy skies with scattered showers and west winds 10-15 mph. This aligns with climatological normals of 54.4°F at O'Hare and recent GFS/ECMWF ensemble guidance showing means in the mid-50s amid a 10-15°F spread due to variable cloud cover and precipitation timing from a lingering low-pressure trough. Persistent light rain over the past 24 hours has cooled surface conditions, while equal-chance spring outlooks from NOAA's Climate Prediction Center add uncertainty; watch 12z model runs Friday for potential shifts before resolution based on official O'Hare observations.
