Latest National Weather Service and ensemble model guidance points to a daily maximum temperature in Chicago on August 21 centered near 80°F, just below the 1991–2020 normal of 82.1°F, which underpins the strong market weighting toward the 80–81°F bin. A northwesterly flow is expected to limit peak heating, with afternoon cloud cover and a modest chance of isolated thunderstorms further capping temperatures in the upper 70s to low 80s. Recent model runs show minimal spread around this range, with only low-probability scenarios supporting 82°F or higher if skies clear earlier than anticipated. These conditions align with broader late-August cooling trends observed in recent days across the Midwest.
