Latest National Weather Service and ensemble model guidance point to a daytime high near 79°F in Chicago on May 18, driven by southerly flow ahead of an approaching warm front that is advecting warmer air and pushing readings several degrees above the May climatological normal of 71°F. Consistent short-range model runs reinforce this setup, with only modest uncertainty from potential convective development or minor steering shifts. The resulting market-implied probability near 75% for 78°F or higher reflects traders' assessment of these stable atmospheric conditions and the low likelihood of a significant cold-air intrusion over the remaining forecast window. Updated model guidance and official briefings in the next 24 hours will further refine the expected maximum before resolution.
