Recent National Weather Service and private model guidance points to a high near 78–81°F in Chicago on July 24, below the 1991–2020 normal of 84.5°F, as a cooler, more stable air mass lingers with lighter winds and possible morning cloud cover limiting daytime heating. Traders have concentrated probability in the 78–81°F brackets because ensemble runs show modest spread driven by small differences in boundary-layer mixing and any weak frontal passage timing. With resolution hinging on the official O’Hare maximum, the tight clustering of odds around these values captures both the current forecast consensus and the realistic range of verification outcomes once final observations are recorded.
