Trader consensus on Polymarket prices a 48% implied probability for Chicago's highest temperature at O'Hare International Airport falling in the 42-43°F range today, driven by the latest National Weather Service forecasts indicating a high near 41°F amid persistent overcast skies and northwesterly winds at 10-15 mph. This positioning reflects a sharp cooldown following a record 81°F high on March 30, as a cold front ushered cooler air masses and increased cloud cover, suppressing diurnal heating below the April 1 climatological normal of 53°F. Current midday observations show temperatures hovering in the low-to-mid 40s with 90%+ humidity, aligning with short-range model consensus from GFS and HRRR runs. Remaining uncertainty stems from potential afternoon cloud breaks, with hourly airport data through sunset at 7:17 PM CDT determining the peak.
