National Weather Service forecasts for Chicago O'Hare International Airport, the market's official observation station, project a high of 55-57°F on April 29 under mostly sunny skies with light northwesterly winds, driving trader consensus to 100% implied probability for 56°F or higher. This aligns with NOAA Global Forecast System and ECMWF ensemble model agreement on persistent upper-level ridging over the Midwest, following a recent warm spell with prior highs in the 60s—still below the April 29 climatological normal of 64°F—and bolsters confidence amid morning observations already near 57°F. Realistic challenges include low-level moisture from Lake Michigan fostering unexpected cloud cover or a subtle frontal shift capping peaks at 54-55°F, with hourly NWS updates and afternoon model runs providing final clarity before evening resolution.
