Trader consensus favors 58°F or higher (52.5% implied probability) for Chicago's highest temperature on April 3, driven by recent National Weather Service guidance and ensemble forecasts from GFS and ECMWF models projecting mid-to-upper 50s amid NOAA Climate Prediction Center's outlook for a warmer-than-average spring across the Midwest. The climatological normal high at Chicago O'Hare is 54°F, but persistent mild upper-air patterns have boosted these odds, though an approaching weather system raises risks of clouds and heavy rain April 3-5 per NWS advisories, supporting 31.5% odds for 39°F or below if cooler air advances. Model spread populates mid-40s to low-50s bins (e.g., 42-43°F at 18%), with daily forecast updates from NOAA offices critical as uncertainty narrows toward resolution.
