Trader consensus on Polymarket has locked in a 100% implied probability for Chicago's highest temperature on March 28, 2026, falling in the 48-49°F range, driven by official observations from Chicago Midway International Airport (KMDW)—the standard reference station for such markets—which recorded a maximum of 48°F around 4-5 PM under mostly cloudy skies. National Weather Service daily climate summaries and automated surface observing system (ASOS) data confirm this peak, with O'Hare (KORD) matching at 48°F amid cooler-than-normal March conditions (historical average high ~52°F). While finalized reports rarely change, a challenge could arise from post-processing quality control revisions for sensor anomalies, though dual-station consistency makes this improbable. No further updates expected as the market nears resolution.
