Trader consensus on Polymarket heavily favors a high temperature of 42-43°F (42%) or 40-41°F (32.5%) at Chicago O'Hare International Airport today, reflecting the National Weather Service's latest forecast of a high near 41°F amid persistent mostly cloudy skies and lingering effects from recent storms. This positioning stems from a sharp cooldown after O'Hare tied its March 30 record high of 87°F, as a cool mid-level air mass overspreads the region under weak high pressure, suppressing diurnal heating. GFS and ECMWF model ensembles show tight clustering in the low-to-mid 40s, with outcomes hinging on cloud cover persistence—partial breaks could boost solar insolation and favor 42-43°F, while overcast conditions lock in the lower bin. Well below the April 1 climatological normal of 53°F, watch NWS hourly updates through afternoon for shifts in boundary layer temperatures.
