Traders have concentrated nearly two-thirds of implied probability on highs of 74–77°F for Chicago on June 15 because the latest forecast guidance from NWS and private models shows a daytime maximum in the low-to-mid 70s. Cooler-than-normal air behind a departing cold front, combined with increasing cloud cover and possible scattered showers, is suppressing temperatures several degrees below the long-term June 15 average high of 80.5°F. Ensemble spreads remain modest, supporting the narrow 76–77°F bin as the mode while limiting upside risk to the 78–79°F tier. Updated model runs and the official NWS point forecast expected overnight will determine whether probabilities shift further toward the current leading outcome.
