Current forecast guidance and climatological normals around 83–84°F are anchoring trader consensus on the 84–85°F outcome at 48% implied probability, with 86–87°F next at 25%. August norms for Chicago place the expected daily maximum near 83.7°F, and broader monthly outlooks show highs typically spanning 77–87°F under moderate atmospheric patterns without an active heat dome or strong southerly flow. Recent model runs have shown limited day-to-day variability in the upper Midwest, keeping probabilities for extremes below 3% while the 82–83°F band retains modest support at 19.5%. Updated National Weather Service guidance and ensemble consensus expected later today could further refine these ranges ahead of market resolution.
