Trader consensus on Polymarket closely splits between 42-43°F (42.5%) and 40-41°F (38%) for Chicago's highest temperature today at O'Hare International Airport, driven by the National Weather Service's latest forecast of a high near 41°F under persistent overcast skies and a 30% chance of showers. Following yesterday's record-tying 81°F warmth, a cold frontal passage has ushered in north-northeast winds at 10-15 mph, capping daytime heating by limiting solar insolation despite near-normal April 1 averages around 53°F. Differentiating factors include potential afternoon cloud breaks in guidance from GFS and ECMWF models, which could allow brief spikes to 43°F, versus sustained stratus and precipitation keeping peaks in the low 40s; hourly observations and the 3 PM CDT forecast update will clarify as the day progresses.
