Current forecast models from the National Weather Service and private ensembles point to a high in the mid-70s for Chicago on August 2, driven by a frontal passage that will advect cooler, drier air southward behind a surface low. This setup favors increased cloud cover and possible scattered showers, limiting diurnal heating below the long-term normal of 84°F for early August. Recent model runs show consistent agreement on this pattern with limited spread, supporting the market's heavy weighting toward the 74–77°F bins while keeping higher temperatures at low implied probability. Updated guidance ahead of the 12Z cycle could refine the exact peak if timing of the front shifts.
