Recent National Weather Service and private forecast models indicate a high near 62–64°F for Chicago on October 2, driven by post-frontal northerly flow and clearing skies following widespread rain on October 1. A cold front has shifted winds from the southwest to the north at 10–15 mph, suppressing afternoon warming and aligning with the market’s strong consensus on the 64–65°F bin. These conditions reflect typical early-autumn cooling after a warm September, with model agreement reducing the chance of exceeding 67°F. Updated NWS guidance and any late adjustments to boundary-layer mixing will be the key near-term catalysts for final resolution.
