This market tracks the lowest temperature recorded in Chicago on July 12, 2026, using official National Weather Service data from Chicago-Midway. The outcome will be determined by the minimum temperature reading on that specific date.
Resolution is based on the minimum temperature recorded at Chicago-Midway on July 12, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 61°F or below, 62-63°F, 64-65°F, 66-67°F, 68-69°F, and 70°F or above. Each range corresponds to a distinct outcome. Official data must be obtained from the NWS Climatological Report accessed through the specified URL, selecting Chicago-Midway with Daily Climate Report. While preliminary NWS data and third-party weather services may provide guidance, the final determination uses only the official NWS Climatological Report (Daily) values. Traders should note that preliminary NWS reporting may involve rounding and conversion nuances that could affect interpretation.
