National Weather Service forecasts for Chicago on August 21 point to an overnight low near 64°F, moderated by Lake Michigan's influence and light winds that limit radiational cooling. Recent model consensus shows limited spread around this value, with historical August normals near 65°F providing context, though variable cloud cover and subtle shifts in lake-breeze patterns could nudge the minimum a degree or two lower or higher. Trader odds cluster tightly across the 56–67°F range, reflecting this narrow uncertainty band rather than strong directional signals, as official observations at O'Hare and Midway will resolve the market based on the precise 24-hour minimum.
