Northwest winds and a post-frontal air mass are keeping Chicago’s August 23 high in the mid-70s, with National Weather Service guidance centering on 74°F under mostly sunny skies. Northwest flow advects cooler Canadian air while limiting moisture and cloud cover, producing modest diurnal heating compared with the 82°F seasonal normal. Model consensus clusters afternoon maxima near 74–76°F, with slight differences in boundary-layer mixing and wind speed creating the tight 74–75°F versus 76–77°F split in trader sentiment. Final NWS updates and any last adjustments to the 10–15 mph breeze will determine which bin resolves.
