Current National Weather Service and ensemble model guidance point to a daytime high near 79°F in Chicago on May 18, well above the 71°F climatological normal, driven by southerly flow ahead of an approaching warm front. This setup, with consistent short-range model consensus and a slight severe-weather risk noted by the Storm Prediction Center, underpins the 75% market-implied probability for 78°F or higher. Any shift below that threshold would require an unexpected cold-air intrusion or major forecast revision, both considered low-probability given the short time horizon and stable steering patterns. Updated model runs over the next 24 hours will further refine the expected maximum before resolution at Chicago O’Hare.
