Recent National Weather Service and NOAA forecast models indicate a highest temperature for Chicago on August 5 most likely in the 78–81°F range, consistent with market-implied odds favoring those bins. Cooler-than-normal conditions stem from northwesterly flow and moderating lake breezes off Lake Michigan, which suppress daytime maxima along the shoreline while historical August averages near 83–84°F. Limited cloud cover and weak southerly advection have kept temperatures from climbing further, though minor model spread around timing of any afternoon mixing introduces uncertainty between the 76–77°F and 80–81°F outcomes. Updated short-range guidance later today could refine these projections ahead of market resolution.
