Trader consensus on Polymarket clusters around 60-65°F for Chicago O'Hare's highest temperature on March 29, reflecting the latest 00z GFS and ECMWF ensemble guidance showing tight spreads in the low-to-mid 60s amid building high-pressure ridging over the Midwest. This follows a sharp cool-down today with overnight lows near 28°F, but southwesterly winds and abundant sunshine are expected to drive daytime heating above the late-March climatological average of 48°F under a neutral-to-weak La Niña pattern. Differentiating factors include model disagreements on cloud timing Saturday night—increased overcast could cap peaks at 60-61°F, while persistent clears favor 64-65°F—against National Weather Service point forecasts nearer 49-57°F. Watch 12z model updates and NWS discussion for refinements before resolution based on official O'Hare observations.
