Latest National Weather Service and model guidance point to a warm southerly flow advecting above-normal air into the Chicago area ahead of a weak frontal boundary, supporting a daytime high in the upper 70s on May 18. This setup follows a recent stretch of temperatures several degrees above the 71 °F climatological normal, with yesterday’s observed high already reaching 82 °F. Ensemble forecasts show limited spread around 77–79 °F, keeping the market-implied probability of 78 °F or higher near 78 %. Resolution will depend on official observations at Chicago Midway or O’Hare, with any northward shift in the front or increased cloud cover the main factors that could trim the peak by a degree or two.
